As shown in the table that follows, diluted earnings per share is computed using weighted average common shares outstanding, plus weighted-average common shares available from the exercise of all dilutive stock options, less the number of shares that could be repurchased with the proceeds of stock option exercises based on the average share price of the Corporation's common stock during the period.

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	5. FAIR VALUE MEASUREMENTS AND FAIR VALUES OF FINANCIAL INSTRUMENTS
	The Corporation measures certain assets at fair value. Fair value is defined as the price that would be received to sell an asset in an orderly transaction between market participants at the measurement date. Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) topic 820, “Fair Value Measurements and Disclosures” establishes a framework for measuring fair value that includes a hierarchy used to classify the inputs used in measuring fair value. The hierarchy prioritizes the inputs used in determining valuations into three levels. The level in the fair value hierarchy within which the fair value measurement falls is determined based on the lowest level input that is significant to the fair value measurement. The levels of the fair value hierarchy are as follows:
	Level 1 – Fair value is based on unadjusted quoted prices in active markets that are accessible to the Corporation for identical assets. These generally provide the most reliable evidence and are used to measure fair value whenever available.
	Level 2 – Fair value is based on significant inputs, other than Level 1 inputs, that are observable either directly or indirectly for substantially the full term of the asset through corroboration with observable market data. Level 2 inputs include quoted market prices in active markets for similar assets, quoted market prices in markets that are not active for identical or similar assets and other observable inputs.
	Level 3 – Fair value is based on significant unobservable inputs. Examples of valuation methodologies that would result in Level 3 classification include option pricing models, discounted cash flows and other similar techniques.
	The Corporation monitors and evaluates available data relating to fair value measurements on an ongoing basis and recognizes transfers among the levels of the fair value hierarchy as of the date of an event or change in circumstances that affects the valuation method chosen. Examples of such changes may include the market for a particular asset becoming active or inactive, changes in the availability of quoted prices, or changes in the availability of other market data.
	At March 31, 2015 and December 31, 2014, assets measured at fair value and the valuation methods used are as follows:

	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. Foreclosed assets held for sale consist of real estate acquired by foreclosure. For impaired commercial loans secured by real estate and foreclosed assets held for sale, estimated fair values are determined primarily using values from third-party appraisals less estimated selling costs.
	Management’s evaluation and selection of valuation techniques and the unobservable inputs used in determining the fair values of assets valued using Level 3 methodologies include sensitive assumptions. Other market participants might use substantially different assumptions, which could result in calculations of fair values that would be substantially different than the amount calculated by management. At March 31, 2015 and December 31, 2014, quantitative information regarding significant techniques and inputs used for assets measured on a recurring basis using unobservable inputs (Level 3 methodologies) are as follows:
			Fair Value at
			3/31/15			Valuation	Unobservable		Method or Value As of
	Asset		(In Thousands)			Technique	Input(s)		3/31/15
Servicing rights			$1,195		Discounted cash flow	Discount rate			10	%		Rate used through modeling period

						Loan prepayment speeds			156	%		Weighted-average PSA
						Servicing fees			0.25	%		of loan balances

									5	%		late fees assessed

									$24.00			Additional monthly servicing cost per loan on loans more than 30 days delinquent
									1.5	%		of loans more than 30 days delinquent
									3	%		annual increase in servicing costs
The fair value of servicing rights is affected by expected future interest rates. Increases (decreases) in future expected interest rates tend to increase (decrease) the fair value of the Corporation’s servicing rights because of changes in expected prepayment behavior by the borrowers on the underlying loans.
Following is a reconciliation of activity for Level 3 assets measured at fair value on a recurring basis:

Certain of the Corporation’s financial instruments are not measured at fair value in the consolidated financial statements. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. Certain financial instruments and all nonfinancial instruments are excluded from disclosure requirements. Therefore, the aggregate fair value amounts presented may not represent the underlying fair value of the Corporation.
The Corporation used the following methods and assumptions in estimating fair value disclosures for financial instruments:
CASH AND CASH EQUIVALENTS - The carrying amounts of cash and short-term instruments approximate fair values.
CERTIFICATES OF DEPOSIT - Fair values for certificates of deposit, included in cash and due from banks in the consolidated balance sheet, are based on quoted market prices for certificates of similar remaining maturities.
SECURITIES - Fair values for securities, excluding restricted equity securities, are based on quoted market prices or other methods as described above. The carrying value of restricted equity securities approximates fair value based on applicable redemption provisions.
LOANS HELD FOR SALE - Fair values of loans held for sale are determined based on applicable sale prices available under the Federal Home Loan Banks’ MPF Original or Xtra program.
LOANS - Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial, commercial real estate, residential mortgage and other consumer. Each loan category is further segmented into fixed and adjustable rate interest terms and by performing and nonperforming categories. The fair value of performing loans is calculated by discounting contractual cash flows, adjusted for estimated prepayments based on historical experience, using estimated market discount rates that reflect the credit and interest rate risk inherent in the loans. Fair value of nonperforming loans is based on recent appraisals or estimates prepared by the Corporation’s lending officers.
SERVICING RIGHTS - The fair value of servicing rights, included in other assets in the consolidated balance sheet, is determined through a discounted cash flow valuation. Significant inputs include expected net servicing income, the discount rate and the expected prepayment speeds of the underlying loans.
DEPOSITS - The fair value of deposits with no stated maturity, such as noninterest-bearing demand deposits, savings, money market and interest checking accounts, is (by definition) equal to the amount payable on demand at March 31, 2015 and December 31, 2014. The fair value of time deposits, such as certificates of deposit and Individual Retirement Accounts, is based on the discounted value of contractual cash flows. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities. The fair value estimates of deposits do not include the benefit that results from the low-cost funding provided by the deposit liabilities compared to the cost of borrowing funds in the market, commonly referred to as the core deposit intangible.
BORROWED FUNDS - The fair value of borrowings is estimated using discounted cash flow analyses based on rates currently available to the Corporation for similar types of borrowing arrangements.
ACCRUED INTEREST - The carrying amounts of accrued interest receivable and payable approximate fair values.
OFF-BALANCE SHEET COMMITMENTS - The Corporation has commitments to extend credit and has issued standby letters of credit. Standby letters of credit are conditional guarantees of performance by a customer to a third party. Estimates of the fair value of these off-balance sheet items were not made because of the short-term nature of these arrangements and the credit standing of the counterparties.
The estimated fair values, and related carrying amounts, of the Corporation’s financial instruments are as follows:
(In Thousands)	Valuation		31-Mar-15								31-Dec-14

The Corporation’s mortgage-backed securities and collateralized mortgage obligations have stated maturities that may differ from actual maturities due to borrowers’ ability to prepay obligations. Cash flows from such investments are dependent upon the performance of the underlying mortgage loans and are generally influenced by the level of interest rates. In the table above, mortgage-backed securities and collateralized mortgage obligations are shown in one period.
Investment securities carried at $386,936,000 at March 31, 2015 and $369,945,000 at December 31, 2014 were pledged as collateral for public deposits, trusts and certain other deposits as provided by law. See Note 8 for information concerning securities pledged to secure borrowing arrangements.
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 evaluation. Consideration is given to (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, and (3) whether the Corporation intends to sell the security or more likely than not will be required to sell the security before its anticipated recovery.
A summary of information management considered in evaluating debt and equity securities for OTTI at March 31, 2015 is provided below.
Debt Securities
At March 31, 2015, management performed an assessment for possible OTTI of the Corporation’s debt securities on an issue-by-issue basis, relying on information obtained from various sources, including publicly available financial data, ratings by external agencies, brokers and other sources. The extent of individual analysis applied to each security depended on the size of the Corporation’s investment, as well as management’s perception of the credit risk associated with each security. Based on the results of the assessment, management believes impairment of debt securities, including municipal bonds with no external ratings, at March 31, 2015 to be temporary.
The credit rating agencies have withdrawn their ratings on numerous municipal bonds held by the Corporation. At March 31, 2015, the total amortized cost basis of municipal bonds with no external credit ratings was $15,704,000, with an aggregate unrealized gain of $185,000. At the time of purchase, each of these bonds was considered investment grade and had been rated by at least one credit rating agency. Most of the bonds for which credit rating agencies have withdrawn their ratings were insured by an entity that has reported significant financial problems and declines in its regulatory capital ratios, and most of the ratings were removed in the fourth quarter 2009. However, the insurance remains in effect on the bonds. In the third quarter 2013, a credit rating agency withdrew its ratings on several bonds due to changes in its rating methodology related to credit enhancement programs provided by issuers’ state governments. However, the credit enhancement remains in effect on the bonds. None of the unrated municipal bonds has failed to make a scheduled payment.
Equity Securities
The Corporation’s marketable equity securities at March 31, 2015 and December 31, 2014 consisted exclusively of stocks of banking companies. The Corporation had no realized gains or losses from the sale of equity securities in the first quarter of 2015 or the first quarter of 2014. At March 31, 2015, the Corporation held three stocks with an unrealized loss of $6,000 for which management determined an OTTI charge was not required.
C&N Bank is a member of the Federal Home Loan Bank of Pittsburgh (FHLB-Pittsburgh). As a member, C&N Bank is required to purchase and maintain stock in FHLB-Pittsburgh. There is no active market for FHLB-Pittsburgh stock, and it must ordinarily be redeemed by FHLB-Pittsburgh in order to be liquidated. C&N Bank’s investment in FHLB-Pittsburgh stock, included in Other Assets in the consolidated balance sheet, was $1,515,000 at March 31, 2015 and $1,454,000 at December 31, 2014. The Corporation evaluated its holding of FHLB-Pittsburgh stock for impairment and deemed the stock to not be impaired at March 31, 2015 and December 31, 2014. In making this determination, management concluded that recovery of total outstanding par value, which equals the carrying value, is expected. The decision was based on review of financial information that FHLB-Pittsburgh has made publicly available.

The most significant classes of commercial loans are commercial loans secured by real estate, non-real estate secured commercial and industrial loans, loans to political subdivisions, commercial construction and land loans, and loans secured by farmland.
	Loans outstanding at March 31, 2015 and December 31, 2014 are summarized as follows:

	The Corporation grants loans to individuals as well as commercial and tax-exempt entities. Commercial, residential and personal loans are made to customers geographically concentrated in the Pennsylvania and New York counties that comprise the market serviced by Citizens & Northern Bank. Although the Corporation has a diversified loan portfolio, a significant portion of its debtors’ ability to honor their contracts is dependent on the local economic conditions within the region. There is no concentration of loans to borrowers engaged in similar businesses or activities that exceed 10% of total loans at either March 31, 2015 or December 31, 2014.
	The Corporation maintains an allowance for loan losses that represents management’s estimate of the losses inherent in the loan portfolio as of the balance sheet date and recorded as a reduction of the investment in loans. 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 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. In the process of evaluating the loan portfolio, management also considers the Corporation’s exposure to losses from unfunded loan commitments. As of March 31, 2015 and December 31, 2014, management determined that no allowance for credit losses related to unfunded loan commitments was required.
	Transactions within the allowance for loan losses, summarized by segment and class, for the three-month periods ended March 31, 2015 and 2014 was as follows:

In the evaluation of the loan portfolio, management determines two major components for the allowance for loan losses – (1) a specific component based on an assessment of certain larger relationships, mainly commercial purpose loans, on a loan-by-loan basis; and (2) a general component for the remainder of the portfolio based on a collective evaluation of pools of loans with similar risk characteristics. The general component is assigned to each pool of loans based on both historical net charge-off experience, and an evaluation of certain qualitative factors. An unallocated component 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 above methodologies for estimating specific and general losses in the portfolio.
In determining the larger loan relationships for detailed assessment under the specific allowance component, the Corporation uses an internal risk rating system. Under the risk rating system, the Corporation classifies problem or potential problem loans as “Special Mention,” “Substandard,” or “Doubtful” on the basis of currently existing facts, conditions and values. Substandard loans include those characterized by the distinct possibility that the Corporation will sustain some loss if the deficiencies are not corrected. Loans classified as Doubtful have all the weaknesses inherent in those classified as Substandard with the added characteristic that the weaknesses present make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. Loans that do not currently expose the Corporation to sufficient risk to warrant classification as Substandard or Doubtful, but possess weaknesses that deserve management’s close attention, are deemed to be Special Mention. Risk ratings are updated any time that conditions or the situation warrants. Loans not classified are included in the “Pass” column in the table below.
The following tables summarize the aggregate credit quality classification of outstanding loans by risk rating as of March 31, 2015 and December 31, 2014:

The general component of the allowance for loan losses covers pools of loans including commercial loans not considered individually impaired, as well as smaller balance homogeneous classes of loans, such as residential real estate, home equity lines of credit and other consumer loans. Accordingly, the Corporation generally does not separately identify individual consumer and residential loans for impairment disclosures, unless such loans are subject to a restructuring agreement. The pools of loans are evaluated for loss exposure based upon three-year average historical net charge-off rates for each loan class, adjusted for qualitative factors. Qualitative risk factors (described in the following paragraph) are evaluated for the impact on each of the three segments (residential mortgage, commercial and consumer) within the loan portfolio. Each qualitative factor is assigned a value to reflect improving, stable or declining conditions based on management’s judgment using relevant information available at the time of the evaluation. The adjustment for qualitative factors is applied as an increase or decrease to the three-year average net charge-off rate to each loan class within each segment.
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 65% at March 31, 2015) is secured by real estate, and accordingly, the Corporation’s risk for the commercial segment is significantly affected by commercial real estate values. The consumer segment includes a wide mix of loans for different purposes, primarily secured loans, including loans secured by motor vehicles, manufactured housing and other types of collateral.
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 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 shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for commercial loans, by the fair value of the collateral (if the loan is collateral dependent), by future cash flows discounted at the loan’s effective rate or by the loan’s observable market price.
The scope of loans evaluated individually for impairment include all loan relationships greater than $200,000 for which there is at least one extension of credit graded Special Mention, Substandard or Doubtful. Also, all loans classified as troubled debt restructurings (discussed in more detail below) and all loan relationships less than $200,000 in the aggregate, but with an estimated loss of $100,000 or more, are individually evaluated for impairment. Loans that are individually evaluated for impairment, but which are not determined to be impaired, are combined with all remaining loans that are not reviewed on a specific basis, and such loans are included within larger pools of loans based on similar risk and loss characteristics for purposes of determining the general component of the allowance. The loans that have been individually evaluated, but which have not been determined to be impaired, are included in the “Collectively Evaluated” column in the tables summarizing the allowance and associated loan balances as of March 31, 2015 and December 31, 2014.

Interest income recognized on impaired loans		185			163
Interest income recognized on a cash basis on impaired loans		185			163
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 recognized on specific impaired loans unless the likelihood of further loss is remote. Interest payments received on loans for which the risk of further loss is greater than remote are applied as a reduction of the loan principal balance. Interest income on other nonaccrual loans is recognized only to the extent of interest payments received. 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. Also, the amortization of deferred loan fees is discontinued when a loan is placed on nonaccrual status.
The breakdown by portfolio segment and class of nonaccrual loans and loans past due ninety days or more and still accruing is as follows:

The events of default in the table listed above resulted from the borrowers’ failure to make timely payments under the following circumstances: (1) for one customer relationship included in the Residential first lien mortgage class, payment was missed after the interest rate and monthly payment amount had been reduced; (2) for the other customer relationship included in the Residential first lien mortgage class, monthly payments were missed after reducing the monthly payments to interest only payments; (3) for the Commercial loan secured by real estate, monthly payments were missed after reducing the monthly payments to interest only; and (4) for the Commercial construction and land loan, monthly payments were missed after extending the term of maturity. There were no allowances for loan losses recorded on these loans at March 31, 2015.
The events of default in 2014 in the table above resulted from one borrower’s failure to make interest only monthly payments. There were no allowances for loan losses recorded on these loans at March 31, 2014.
At March 31, 2015, the carrying amount of foreclosed residential real estate properties held as a result of obtaining physical possession (included in Foreclosed assets held for sale in the unaudited consolidated balance sheet) was $761,000.
At March 31, 2015, the recorded investment of consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings are in process was $1,366,000.

Compensation and Retirement Disclosure [Abstract]
Pension and Other Postretirement Benefits Disclosure [Text Block]	9. DEFINED BENEFIT PLANS
	The Corporation sponsors a defined benefit health care plan that provides postretirement medical benefits and life insurance to employees who meet certain age and length of service requirements. Full-time employees no longer accrue service time toward the Corporation-subsidized portion of the medical benefits. This plan contains a cost-sharing feature, which causes participants to pay for all future increases in costs related to benefit coverage. Accordingly, actuarial assumptions related to health care cost trend rates do not significantly affect the liability balance at March 31, 2015 and December 31, 2014, and are not expected to significantly affect the Corporation's future expenses. The Corporation uses a December 31 measurement date for the postretirement plan.
	In an acquisition in 2007, the Corporation assumed the Citizens Trust Company Retirement Plan, a defined benefit pension plan. This plan covers certain employees who were employed by Citizens Trust Company on December 31, 2002, when the plan was amended to discontinue admittance of any future participant and to freeze benefit accruals. Information related to the Citizens Trust Company Retirement Plan has been included in the tables that follow. The Corporation uses a December 31 measurement date for this plan.
	The components of net periodic benefit costs from these defined benefit plans are as follows:
	Defined Benefit Plans

	In the first three months of 2015, the Corporation funded postretirement contributions totaling $18,000, with estimated annual postretirement contributions of $65,000 expected in 2015 for the full year. Based upon the related actuarial reports, no defined benefit pension contributions are required in 2015, though the Corporation may make discretionary contributions.

	The Corporation has a Stock Incentive Plan for a selected group of officers. Also, the Corporation has an Independent Directors Stock Incentive Plan. In the first quarter 2015, the Corporation issued restricted stock under each of the Plans. In the first quarter 2014, the Corporation issued stock options and restricted stock under each of the Plans.
	In the first quarter 2015, the Corporation awarded a total of 34,800 shares of restricted stock under the Stock Incentive and Independent Directors Stock Incentive Plans. In the first quarter 2014, a total of 16,711 shares of restricted stock were awarded under the Plans. Restricted stock awards in the first quarter 2015 included the following: (1) a total of 20,298 shares to employees, vesting over a four-year term, with vesting contingent upon the Corporation meeting an annual return on average equity (“ROAE”) performance ratio, as defined; (2) a total of 2,198 shares to employees, vesting over a four-year term, with vesting dependent on satisfactory performance; (3) an award to the Chief Executive Officer of 5,174 shares, vesting over a three-year term, with vesting dependent on satisfactory performance; and (4) a total of 7,130 shares under the Independent Directors Incentive Plan, vesting over a term of one year.
	Compensation cost related to restricted stock is recognized based on the market price of the stock at the grant date over the vesting period. Management has estimated restricted stock expense in the first quarter 2015 based on an assumption that the ROAE target for 2015 will be met.
	In January 2014, the Corporation granted options to purchase a total of 39,027 shares of common stock. The exercise price for the 2014 awards is $20.45 per share, based on the market price as of the date of grant. Stock option expense is recognized over the vesting period of each option.
	The Corporation records stock option expense based on estimated fair value calculated using an option valuation model. In calculating the 2014 fair value, the Corporation utilized the Black-Scholes-Merton option-pricing model. The calculated fair value of each option granted, and significant assumptions used in the calculations, were as follows:
		2014
	Fair value of each option granted		$5.50
	Volatility		39%
	Expected option lives (in years)		8
	Risk-free interest rate		2.85%
	Dividend yield		4.33%
	In calculating the estimated fair value of stock option awards, management based its estimates of volatility and dividend yield on the Corporation’s experience over the immediately prior period of time consistent with the estimated lives of the options. The risk-free interest rate was based on the published yield of zero-coupon U.S. Treasury strips with an applicable maturity as of the grant dates. The expected option lives were based on management’s estimates of the average term for all options issued under both plans. In 2014, management assumed a 34% forfeiture rate for options granted under the Stock Incentive Plan, and a 3% forfeiture rate for the Directors Stock Incentive Plan. These estimated forfeiture rates were determined based on the Corporation’s historical experience.
	Total stock-based compensation expense is as follows:

	The provision for income tax for the three-month periods ended March 31, 2015 and 2014 is based on the Corporation’s estimate of the effective tax rate expected to be applicable for the full year. The effective tax rates for the Corporation are as follows:
		Three Months Ended
	(In thousands)	March 31,

	Income before income tax provision	$	5,044		$	5,687
	Income tax provision		1,229			1,399
	Effective tax rate		24.37	%		24.6	%
	The effective tax rate for each period presented differs from the statutory rate of 35% principally because of the effects of tax-exempt interest income.
	The Corporation has investments in three limited partnerships that manage affordable housing projects that have qualified for the federal low-income housing tax credit. The Corporation’s expected return from these investments is based on the receipt of tax credits and tax benefits from deductions of operating losses. The Corporation uses the effective yield method to account for these investments, with the benefits recognized as a reduction of the provision for income taxes. For two of the three limited partnership investments, the tax credits have been received in full in prior years, and the Corporation has fully realized the benefits of the credits and amortized its initial investments in the partnerships. The most recent affordable housing project was completed in 2013, and the Corporation received tax credits in 2013 and 2014 and expects to continue to receive tax credits annually through 2022. The carrying amount of the Corporation’s investment is $884,000 at March 31, 2015 and $906,000 at December 31, 2014 (included in Other Assets in the consolidated balance sheets). For the year ending December 31, 2015, the estimated amount of tax credits and other tax benefits to be received is $158,000 and the estimated amount to be recognized as a reduction of the provision for income taxes is $80,000. For the year ended December 31, 2014, tax credits and other tax benefits totaled $159,000 and the amount recognized as a reduction of the provision for income taxes for 2014 was $83,000. In the first quarters 2015 and 2014, the total reduction in the provision for income taxes resulting from this investment is $20,000 and $21,000, respectively.
	The Corporation has no unrecognized tax benefits, nor pending examination issues related to tax positions taken in preparation of its income tax returns. With limited exceptions, the Corporation is no longer subject to examination by the Internal Revenue Service for years prior to 2010.

Accounting Changes and Error Corrections [Abstract]
Accounting Changes and Error Corrections [Text Block]	13. RECENT ACCOUNTING PRONOUNCEMENTS
	The FASB issues Accounting Standards Updates (ASUs) to the FASB ASC. This section provides a summary description of recent ASUs that have significant implications (elected or required) within the consolidated financial statements, or that management expects may have a significant impact on financial statements issued in the near future.
	In January 2014, the FASB issued ASU 2014-01, Accounting for Investments in Qualified Affordable Housing Projects. This Update provides guidance on accounting for investments in flow-through limited liability entities that qualify for the federal low-income housing tax credit. Currently, under U.S. GAAP, a reporting entity that invests in a qualified affordable housing project may elect to account for that investment using the effective yield method if certain conditions are met, or alternatively, the investment would be accounted for under either the equity method or the cost method. Generally, investors in qualified affordable housing project investments expect to receive all of their return through the receipt of tax credits and tax deductions from operating losses, and use of the effective yield method results in recognition of the return as a reduction of income tax expense over the period of the investment. The amendments in this Update modify the conditions that a reporting entity must meet to be eligible to use a method other than the equity or cost methods to account for investments in qualified affordable housing projects. Additionally, the amendments introduce new recurring disclosure requirements about investments in qualified affordable housing projects. The amendments in this Update became effective for the Corporation for annual and interim periods beginning in the first quarter 2015, and are to be applied retrospectively. Information concerning the Corporation’s investments in qualified affordable housing projects is provided in Note 11 to these unaudited consolidated financial statements.
	In January 2014, the FASB issued ASU 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The objective of the amendments in this Update is to reduce diversity among reporting entities by clarifying when an in substance foreclosure occurs. The amendments in this Update clarify that an in substance foreclosure occurs, and a creditor is considered to have received physical possession of residential real property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the amendments require interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to the requirements of the applicable jurisdiction. An entity can elect to adopt the amendments in this Update using either a modified retrospective transition method or a prospective transition method. Under the modified retrospective transition method, an entity would record a cumulative-effect adjustment to residential consumer mortgage loans and foreclosed residential real estate properties existing as of the beginning of the annual period for which the amendments are effective. For prospective transition, an entity would apply the amendments to all instances of an entity receiving physical possession of residential real estate property collateralizing consumer mortgage loans that occur after the date of adoption. Early adoption is permitted. The amendments in this Update became effective for the Corporation for annual and interim periods beginning in the first quarter 2015. The Corporation has applied the amendments to its accounting and reporting practices prospectively in the first quarter 2015. Disclosures required by the Update are provided in Note 7 to these unaudited consolidated financial statements.
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which provides a principles-based framework for revenue recognition that supersedes virtually all previously issued revenue recognition guidance under U.S. GAAP. Additionally, the ASU requires improved disclosures to help users of financial statements better understand the nature, amount, timing, and uncertainty of revenue that is recognized. The core principle of the five-step revenue recognition framework is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 would be effective for all annual and interim periods beginning in the first quarter 2017; however, in April 2015 the FASB issued an Exposure Draft that (if issued after the FASB’s deliberation) would defer the effective date for the Corporation until the first quarter 2018. The amendments in the ASU should be applied either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying this ASU recognized at the date of initial application. The Corporation is in the process of evaluating the potential impact of adopting this ASU, including determining which transition method to apply.
	In June 2014, the FASB issued ASU 2014-11, Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures. In addition to various other amendments that will affect accounting and disclosures for transactions in which the Corporation has not engaged to date, this Update requires expanded disclosures for repurchase agreements that are accounted for as secured borrowings, including: (1) a disaggregation of the gross obligation by the class of collateral pledged, (2) the remaining contractual tenor of the agreements and (3) a discussion of the potential risks associated with the agreements and the related collateral pledged, including obligations arising from a decline in the fair value of the collateral pledged and how those risks are managed. The expanded disclosure requirements associated with repurchase agreements are effective for the Corporation for annual and interim periods beginning in the second quarter 2015. Information concerning the Corporation’s repurchase agreements is provided in Note 8 to these consolidated financial statements.
	In August 2014, the FASB issued ASU 2014-14, Receivables – Troubled Debt Restructuring by Creditors, which requires that a mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if the following conditions are met: (1) the loan has a government guarantee that is not separable from the loan before foreclosure, (2) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under the claim and (3) at the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. The amendments in this Update became effective for the Corporation for annual and interim periods beginning in the first quarter 2015, and the impact of the amendment was not significant to the Corporation.
