| Investment, Policy [Policy Text Block] | INVESTMENT SECURITIES Investment securities that are classified as “held to maturity” are stated at cost, and adjusted for accumulated amortization of premium and accretion of discount. The Bank has the intention and, in Management’s opinion, the ability to hold these investment securities until maturity. Investment securities that are classified as “available for sale” are stated at estimated market value, with the related unrealized gains and losses reported as an amount, net of taxes, as a component of stockholders’ equity. The market value of securities is based on quoted market prices. For securities that do not have readily available market values, estimated market values are calculated based on the market values of comparable securities. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Declines in the fair value of held-to-maturity and available-for-sale securities below their cost that are deemed to be other than temporary are reflected in earnings as realized losses. In estimating other-than-temporary impairment losses, management considers the length of time and the extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer, and the intent and ability of the Corporation to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. Management evaluates securities for other-than-temporary impairment (“OTTI”) on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. When evaluating investment securities consideration is given to the length of time and the extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer, whether the market decline was affected by macroeconomic conditions and whether the Company 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. In analyzing an issuer’s financial condition, the Company may consider whether the securities are issued by the federal government or its agencies, or U.S. Government sponsored enterprises, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuer’s financial condition. 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 OTTI occurs, the amount of the OTTI recognized in earnings depends on whether an entity intends to sell the security or it is more likely than not it will be required to sell the security before recovery of its amortized cost basis. If an entity intends to sell or it is more likely than not it will be required to sell the security before recovery of its amortized cost basis, the OTTI 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. The previous amortized cost basis less the OTTI recognized in earnings becomes the new amortized cost basis of the investment. If a security is determined to be other-than-temporarily impaired, but the entity does not intend to sell the security, only the credit portion of the estimated loss is recognized in earnings, with the other portion of the loss recognized in other comprehensive income. |

| Finance, Loan and Lease Receivables, Held-for-investment, Policy [Policy Text Block] | LOANS The Bank grants mortgage, commercial, and consumer loans to customers. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are reported at their outstanding unpaid principal balances adjusted for charge-offs, the allowance for loan losses, and any deferred fees or costs on originated loans. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method. The accrual of interest on loans is discontinued at the time the loan is 90 days delinquent unless the credit is well secured and in the process of collection. In all cases, loans are placed on nonaccrual or charged off at an earlier date if principal or interest is considered doubtful.All interest accrued but not collected for loans that are placed on nonaccrual or charged off is reversed against interest income. The interest on these loans is accounted for on the cash basis or cost recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. |

| Federal Home Loan Bank Advances [Policy Text Block] | FEDERAL HOME LOAN BANK STOCK The Bank is a member of the Federal Home Loan Bank of Indianapolis (FHLBI). Members are required to own a certain amount of stock based on the level of borrowings and other factors. Stock in the FHLBI is recorded at redemption value which approximates fair value. The Company periodically evaluates the FHLBI stock for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Finance, Loan and Lease Receivables, Held-for-sale, Policy [Policy Text Block] | LOANS HELD FOR SALE Loans held for sale consist of fixed rate residential mortgage loans with maturities of 10 to 30 years. Such loans are recorded at the lower of aggregate cost or estimated fair value. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block] | ALLOWANCE FOR LOAN LOSSES The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based upon management's periodic review of the collectibility of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower's ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.The allowance consists of specific, general, and unallocated components. The specific component relates to loans that are classified as non-accrual or renegotiated. For such loans that are also classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers non-classified loans and is based on historical loss experience, adjusted for qualitative factors. An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probably 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 loan is considered impaired when, based on current information and events, it is probable that the Corporation will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered 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 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. Impairment is measured on a loan by loan basis for commercial and construction loans by either the present value of expected future cash flows discounted at the loan's effective interest rate, the loan's obtainable market price, or the fair value of the collateral if the loan is collateral dependent. Troubled debt restructuring of loans is undertaken to improve the likelihood that the loan will be repaid in full under the modified terms in accordance with a reasonable repayment schedule. All modified loans are evaluated to determine whether the loans should be reported as Troubled Debt Restructurings (TDR). A loan is a TDR when the Bank, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession to the borrower by modifying a loan. To make this determination, the Bank must determine whether (a) the borrower is experiencing financial difficulties and (b) the Bank granted the borrower a concession. This determination requires consideration of all of the facts and circumstances surrounding the modification. An overall general decline in the economy or some deterioration in a borrower’s financial condition does not automatically mean the borrower is experiencing financial difficulties. Large groups of homogeneous loans are collectively evaluated for impairment. Accordingly, the Corporation does not separately identify individual consumer and residential loans for impairment disclosures. |

| Finance, Loan and Lease Receivables, Held for Investments, Foreclosed Assets Policy [Policy Text Block] | FORECLOSED ASSETS (INCLUDES OTHER REAL ESTATE OWNED) Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at the lower of fair value less costs to sell or the loan carrying amount at the date of the foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by Management and the assets are carried at the lower of carrying amount or fair value less cost to sell. Expenses from operations and changes in the valuation allowance are included in net expenses from foreclosed assets. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Property, Plant and Equipment, Policy [Policy Text Block] | BANK PREMISES AND EQUIPMENT Bank premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed generally on the straight-line method over the estimated useful lives of the assets. Upon the sale or other disposition of assets, the cost and related accumulated depreciation are retired and the resulting gain or loss is recognized. Maintenance and repairs are charged to expense as incurred, while renewals and improvements are capitalized. Software costs related to externally developed systems are capitalized at cost less accumulated amortization. Amortization is computed on the straight-line method over the estimated useful life. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Bank Owned Life Insurance [Policy Text Block] | BANK OWNED LIFE INSURANCE Bank owned life insurance policies are stated at the current cash surrender value of the policy, or the policy death proceeds less any obligation to provide a death benefit to an insured’s beneficiaries if that value is less than the cash surrender value. Increases in the asset value are recorded as earnings in other income. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Comprehensive Income, Policy [Policy Text Block] | COMPREHENSIVE INCOME Accounting principles generally require that revenue, expenses, gains, and losses be included in net income. Certain changes in assets and liabilities, however, such as unrealized gains and losses on securities available for sale, and amounts recognized related to postretirement benefit plans (gains and losses, prior service costs, and transition assets or obligations), are reported as a direct adjustment to the equity section of the balance sheet. Such items, along with net income, are components of comprehensive income. The components of accumulated other comprehensive loss and related tax effects are as follows:
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Cash and Cash Equivalents, Policy [Policy Text Block] | CASH AND CASH EQUIVALENTS For the purpose of the consolidated statement of cash flows, cash and cash equivalents include cash and balances due from banks and federal funds sold which mature within 90 days. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Income Tax, Policy [Policy Text Block] | INCOME TAXES Deferred income tax assets and liabilities are determined using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is determined based on the tax effects of the various temporary differences between the book and tax bases of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block] | STOCK-BASED COMPENSATION The Corporation has several stock based compensation plans (Note 15). The total amount of compensation is measured at the fair value of the awards when granted, and this cost is expensed over the required service period, which is normally the vesting period of the options. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Off-Balance-Sheet Credit Exposure, Policy [Policy Text Block] | OFF BALANCE SHEET INSTRUMENTS In the ordinary course of business, the Corporation has entered into commitments to extend credit, including commitments under credit card arrangements, commercial letters of credit and standby letters of credit. Such financial instruments are recorded when they are funded. Additional information regarding Off Balance Sheet Instruments is included in Note 17 in these Notes to Consolidated Financial Statements. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Fair Value Measurement, Policy [Policy Text Block] | FAIR VALUE The Corporation measures or monitors many of its assets and liabilities on a fair value basis. Fair value is used on a recurring basis for assets and liabilities that are elected to be accounted for under the Fair Value Option as well as for certain assets and liabilities in which fair value is the primary basis of accounting. Examples of these include derivative instruments and available for sale securities. Additionally, fair value is used on a non-recurring basis to evaluate assets or liabilities for impairment or for disclosure purposes. Examples of these non-recurring uses of fair value include certain loans held for sale accounted for on a lower of cost or market basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Depending on the nature of the asset or liability, the Corporation uses various valuation techniques and assumptions when estimating fair value. The Corporation applied the following fair value hierarchy: Level 1 – inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. The Corporation’s mutual fund investments where quoted prices are available in an active market generally are classified within Level 1 of the fair value hierarchy.Level 2 – Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. The Corporation’s borrowed funds and investments in U.S. government agency securities, government sponsored mortgage backed securities, and obligations of states and political subdivisions are generally classified in Level 2 of the fair value hierarchy. Fair values for these instruments are estimated using pricing models, quoted prices of securities with similar characteristics, or discounted cash flows.Level 3 – Inputs to the valuation methodology are unobservable and significant to the fair value measurement. Private equity investments and certain municipal debt obligations are classified within Level 3 of the fair value hierarchy. Fair values are initially valued based on transaction price and are adjusted to reflect exit values.When determining the fair value measurements for assets and liabilities required or permitted to be recorded at and/or marked to fair value, the Corporation considers the principal or most advantageous market in which it would transact and considers assumptions that market participants would use when pricing the asset or liability. When possible, the Corporation looks to active and observable markets to price identical assets or liabilities. When identical assets and liabilities are not traded in active markets, the Corporation looks to market observable data for similar assets or liabilities. Nevertheless, certain assets and liabilities are not actively traded in observable markets and the Corporation must use alternative valuation techniques to derive a fair value measurement. |

| New Accounting Pronouncements, Policy [Policy Text Block] | RECENT ACCOUNTING PRONOUNCEMENTS The Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2015 -14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date. The ASU adopts a standardized approach for revenue recognition and was a joint effort with the International Accounting Standards Board (IASB). The new revenue recognition standard is based on a core principle of recognizing 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. The ASU does not apply to financial instruments. The ASU is effective for public entities for annual reporting periods beginning after December 15, 2017, including interim periods within that period (therefore, for the year ending December 31, 2018 for the Corporation). Early adoption is permitted only as of annual periods beginning after December 15, 2016, including interim periods within that period. Management does not expect the standard will have a significant effect on the Corporation’s consolidated financial statements, however the exact effect is still being determined.In January 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016 -01, Recognition and Measurement of Financial Assets and Financial Liabilities. The ASU covers various changes to the accounting, measurement, and disclosures related to certain financial instruments, including requiring equity investments to be accounted for at fair value with changes recorded through earnings, the use of the exit price when measuring fair value, and disaggregation of financial assets and liabilities by category for disclosure purposes. The new guidance will be effective for the Company's year ending December 31, 2018. Early adoption is permitted as early as periods ending after December 31, 2017 with some additional options for early application. The Company does not believe adopting the provisions of ASU No. 2016 -01 in the future will have a material impact on the consolidated financial statements. The Company has not yet quantified the impact of the change.In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016 -13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments. The ASU includes increased disclosures and various changes to the accounting and measurement of financial assets including the Company’s loans and available-for-sale and held-to-maturity debt securities. Each financial asset presented on the balance sheet would have a unique allowance for credit losses valuation account that is deducted from the amortized cost basis to present the net carrying value at the amount expected to be collected on the financial asset. The amendments in this ASU also eliminate the probable initial recognition threshold in current GAAP and instead, reflect an entity’s current estimate of all expected credit losses using reasonable and supportable forecasts. The new credit loss guidance will be effective for the Company's year ending December 31, 2020. Upon adoption, the ASU will be applied using a modified retrospective transition method to the beginning of the first reporting period in which the guidance is effective. A prospective transition approach is required for debt securities for which an other-than-temporary impairment had been recognized before the effective date. Early adoption for all institutions is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The standard will have a significant effect on the Company's consolidated financial statements as credit losses will be accelerated with the elimination of the probable threshold for initial recognition. |
