Organization, Consolidation and Presentation of Financial Statements [Abstract]
Significant Accounting Policies [Text Block]	NOTE 1 - Summary of Significant Accounting Policies Principles of Consolidation Use of Estimates Concentrations of Credit Risk Cash Flow Reporting Certificates of deposits in other financial institutions Securities The Bancorp considers the following factors when determining an other-than-temporary impairment for a security: the length of time and the extent to which the market value has been less than amortized cost; the financial condition and near-term prospects of the issuer; the underlying fundamentals of the relevant market and the outlook for such market for the near future; and an assessment of whether the Bancorp has (1) the intent to sell the debt security or (2) it is more likely than not that the Bancorp will be required to sell the debt security before its anticipated market recovery. If either of these conditions are met, management will recognize other-than-temporary impairment. If, in management’s judgment, an other-than-temporary impairment exists, the cost basis of the security will be written down for the credit loss, and the unrealized credit loss will be transferred from accumulated other comprehensive loss as an immediate reduction of current earnings. Loans Held-for-Sale Mortgage loans held-for-sale can be sold with servicing rights retained or released. The carrying value of mortgage loans sold is reduced by the amount allocated to the servicing rights. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold. Loans and Loan Income The accrual of interest income on mortgage and commercial loans is discontinued at the time the loan is 90 days delinquent unless the loan is well-secured and in process of collection. Consumer loans are typically charged-off no later than when they reach 120 days past due. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on non-accrual or charged-off status at an earlier date if collection of principal or interest is considered doubtful. Generally, interest accrued but not received for loans placed on non-accrual status is reversed against interest income. Interest received on such 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. Allowance for Loan Losses A loan is considered impaired when, based on current information and events, it is probable that the Bancorp 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 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. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Bancorp does not separately identify individual consumer and residential loans for impairment disclosures. Troubled Debt Restructures Some of the factors considered by management when determining whether a borrower is experiencing financial difficulties are: (1) is the borrower currently in default on any of its debts, (2) has the borrower declared or is the borrower in the process of declaring bankruptcy, and (3) absent the current modification, the borrower would likely default. Federal Home Loan Bank Stock – Transfers of Financial Assets Premises and Equipment Foreclosed Real Estate Long-term Assets Bank Owned Life Insurance Goodwill and Intangibles Repurchase Agreements Income Taxes At December 31, 2017 and 2016, the Bancorp evaluated tax positions taken for filing with the Internal Revenue Service and all state jurisdictions in which it operates. The Bancorp believes that income tax filing positions will be sustained under examination and does not anticipate any adjustments that would result in a material adverse effect on the Bancorp's financial condition, results of operations, or cash flows. Accordingly, the Bancorp has not recorded any reserves or related accruals for interest and penalties for uncertain tax positions at December 31, 2017 and 2016.

Management has the intent and ability to hold the securities for the foreseeable future, and the decline in fair value is largely due to changes in interest rates and volatility in the securities markets. The fair values are expected to recover as the securities approach maturity.

The use and application of theses grades by the Bancorp is uniform and conforms to regulatory definitions. The loan grading system is as follows: 1 – Minimal Risk Borrower demonstrates exceptional credit fundamentals, including stable and predictable profit margins, strong liquidity and a conservative balance sheet with superior asset quality. Excellent cash flow coverage of existing and projected debt service. Historic and projected performance indicates borrower is able to meet obligations under almost any economic circumstances. 2 – Moderate risk Borrower consistently internally generates sufficient cash flow to fund debt service, working assets, and some capital expenditures. Risk of default considered low. 3 – Above average acceptable risk Borrower generates sufficient cash flow to fund debt service and some working assets and/or capital expansion needs. Profitability and key balance sheet ratios are at or slightly above peers. Current trends are positive or stable. Earnings may be level or trending down slightly or be erratic; however, positive strengths are offsetting. Risk of default is reasonable but may warrant collateral protection. 4 – Acceptable risk Borrower generates sufficient cash flow to fund debt service, but most working asset and all capital expansion needs are provided from external sources. Profitability ratios and key balance sheet ratios are usually close to peers but one or more ratios (e.g. leverage) may be higher than peer. Earnings may be trending down over the last three years. Borrower may be able to obtain similar financing from other banks with comparable or less favorable terms. Risk of default is acceptable but requires collateral protection. 5 – Marginally acceptable risk Borrower may exhibit excessive growth, declining earnings, strained cash flow, increasing leverage and/or weakening market position that indicate above average risk. Limited additional debt capacity, modest coverage, and average or below average asset quality, margins and market share. Interim losses and/or adverse trends may occur, but not to the level that would affect the Bank’s position. The potential for default is higher than normal but considered marginally acceptable based on prospects for improving financial performance and the strength of the collateral. 6 – Pass/monitor The borrower has significant weaknesses resulting from performance trends or management concerns. The financial condition of the company has taken a negative turn and may be temporarily strained. Cash flow may be weak but cash reserves remain adequate to meet debt service. Management weaknesses are evident. Borrowers in this category will warrant more than the normal level of supervision and more frequent reporting. 7 – Special mention (watch) Special mention credits are considered bankable assets with no apparent loss of principal or interest envisioned but requiring a high level of management attention. Assets in this category are currently protected but are potentially weak. These borrowers are subject to economic, industry, or management factors having an adverse impact upon their prospects for orderly service of debt. The perceived risk in continued lending is considered to have increased beyond the level where such loans would normally be granted. These assets constitute an undue and unwarranted credit risk, but not to the point of justifying a classification of Substandard. 8 – Substandard This classification consists of loans which are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged. Financial statements normally reveal some or all of the following: poor trends, lack of earnings and cash flow, excessive debt, lack of liquidity, and the absence of creditor protection. Loans are still considered collectible, but due to increased risks and defined weaknesses of the credit, some loss could be incurred in collection if the deficiencies are not corrected. 9 – Doubtful This classification consists of loans where the possibility of loss is high after collateral liquidation based upon existing facts, market conditions, and value. Loss is deferred until certain important and reasonably specific pending factors which may strengthen the credit can be exactly determined. These factors may include proposed acquisitions, liquidation procedures, capital injection and receipt of additional collateral, mergers or refinancing plans. Performing loans are loans that are paying as agreed and are approximately less than ninety days past due on payments of interest and principal.

No troubled debt restructurings defaulted during 2017. All of the loans classified as troubled debt restructurings are also considered impaired. The valuation basis for the Bancorp’s troubled debt restructurings is based on the present value of cash flows, unless consistent cash flows are not present, then the fair value of the collateral securing the loan is the basis for valuation.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets Disclosure [Text Block]	Note 6 – Goodwill and Other Intangible Assets The Bancorp established a goodwill balance totaling $2.8 million with the acquisitions of First Federal Savings & Loan (First Federal) and Liberty Savings Bank (Liberty Savings). Goodwill of $2.0 million was established with the acquisition of First Federal and goodwill of $804 thousand was established with the acquisition of Liberty Savings. Goodwill is tested annually for impairment. Goodwill arising from business combinations represents the value attributable to unidentifiable intangible assets in the business acquired. The Bancorp’s goodwill relates to the value inherent in the banking industry and that value is dependent upon the ability of the Bancorp to provide quality, cost effective banking services in a competitive marketplace. If the implied fair value of goodwill is lower than its carrying amount, goodwill impairment is indicated and goodwill is written down to its implied fair value. There has not been any impairment of goodwill identified or recorded. During the second quarter of 2016, original estimates related to Liberty Savings goodwill components were adjusted. Estimates of fair values related to a pool of purchased loans were determined to be lower than originally estimated, which led to the addition of $178 thousand to goodwill. Fixed asset valuations were also determined to be higher than originally estimated, which led to a reduction of $109 thousand to goodwill. Also, the valuation of the accrued withdrawal liability for the defined benefit plan was determined to be higher than originally estimated leading to the addition of $162 thousand to goodwill. Goodwill totaled $2.8 million at December 31, 2017 and December 31, 2016. In addition to goodwill, a core deposit intangible of $93 thousand for the acquisition of First Federal was established and is being amortized over 7.9 years on a straight line basis. Approximately $12 thousand of amortization was taken during the years ended December 31, 2017 and December 31, 2016. It is estimated that $12 thousand of additional amortization will occur annually from 2018 through 2021, and the remaining amount will be amortized through to the first quarter of 2022. A core deposit intangible of $471 thousand for the acquisition of Liberty Savings was established and is being amortized over 8.2 years on a straight line basis. Approximately $58 thousand of amortization was taken during the years ended December 31, 2017 and December 31, 2016. It is estimated that $58 thousand of additional amortization will occur annually from 2018 to 2022, and the remaining amount will be amortized through to the third quarter of 2023. For the First Federal acquisition, as part of the fair value of loans receivable, a net fair value discount was established for residential real estate, including home equity lines of credit, of $1.1 million that is being accreted over 55 months on a straight line basis. Approximately $149 thousand of accretion was taken into income for the year ended December 31, 2017, compared to $217 thousand for the year ended December 31, 2016. It is estimated that $160 thousand of accretion will occur in 2018. Similarly, for the Liberty Savings acquisition, as part of the fair value of loans receivable, a net fair value discount was established for residential real estate, including home equity lines of credit, of $1.2 million that is being accreted over 44 months on a straight line basis. Approximately $307 thousand of accretion was taken into income for the year ended December 31, 2017, compared to $389 thousand of accretion was taken into income for the year ended December 31, 2016. It is estimated that $264 thousand of accretion will occur during 2018, and accretion of $44 thousand will occur during 2019. For the Liberty Savings acquisition, as part of the fair value of certificates of deposit, a fair value premium was established of $124 thousand that was amortized over 17 months on a straight line basis. No amortization was taken as expense during the year ended December 31, 2017, compared to $80 thousand of amortization taken as expense during the year ended December 31, 2016.

Among other changes, the Act reduces the corporate federal income tax rate from 34% to 21% effective January 1, 2018. As a result of these changes made by the Act, the Bancorp made the determination to revalue its net deferred tax asset, as deferred tax assets and liabilities are to be measured using enacted rates expected to apply in years in which the deferred tax assets and liabilities are expected to be recovered or settled. The revaluation of the deferred tax assets and liabilities are adjusted through income tax expense in the year the changes in tax laws are enacted. The revaluation of the net deferred tax asset resulted in additional income tax expense of $517 thousand for 2017. The $517 thousand tax expense was $628 thousand net of a tax benefit of $111 thousand relating to the other comprehensive income revaluation adjustment. At December 31, 2017, the Bancorp has a state net operating loss carry forward of approximately $6.9 million which will begin to expire in 2024 if not used. The Bancorp also has a state tax credit carry forward of approximately $126 thousand which has begun to expire in 2017 and will continue to expire if not used. Management has concluded that the state net operating loss will be fully utilized and therefore no valuation allowance is necessary on the state net operating loss. A valuation allowance remains in place on the state tax credit carryforward. A valuation allowance of $80 thousand and $98 thousand was provided at December 31, 2017 and December 31, 2016, respectively, for the state tax credits. The Bancorp qualified under provisions of the Internal Revenue Code, to deduct from taxable income a provision for bad debts in excess of the provision for such losses charged to income in the financial statements, if any. Accordingly, retained earnings at December 31, 2017 and 2016 includes, approximately $6.0 million for which no provision for federal income taxes has been made. If, in the future this portion of retained earnings is used for any purpose other than to absorb bad debt losses, federal income taxes would be imposed at the then applicable rate. The unrecorded deferred income tax liability on the above amounts was approximately $1.3 million and $2.0 million at December 31, 2017 and 2016. The Bancorp had no unrecognized tax benefits at any time during 2017 or 2016 and does not anticipate any significant increase or decrease in unrecognized tax benefits during 2018. Should the accrual of any interest or penalties relative to unrecognized tax benefits be necessary, it is the Bancorp's policy to record such accruals through income tax accounts; no such accruals existed at any time during 2017 or 2016. The Bancorp and its subsidiaries are subject to US Federal income tax as well as income tax of the states of Indiana and Illinois. The Bancorp is no longer subject to examination by taxing authorities for the years before 2014 for federal and 2013 for state.

Compensation and Retirement Disclosure [Abstract]
Compensation and Employee Benefit Plans [Text Block]	Note 10 – Employees’ Benefit Plans The Bancorp maintains an Employees’ Savings and Profit Sharing Plan and Trust for all employees who meet the plan qualifications. Employees are eligible to participate in the Employees’ Savings and Profit Sharing Plan and Trust on the next January 1 or July 1 following the completion of one year of employment, attaining age 18, and completion of 1,000 hours of service. The Employees’ Savings Plan feature allows employees to make pre-tax contributions to the Employees’ Savings Plan of 1% to 50% of Plan Salary, subject to limitations imposed by Internal Revenue Code section 401(k). Employees are able to begin deferring effective the first of the month following 90 days of employment. The Profit Sharing Plan and Trust feature is non-contributory on the part of the employee. Contributions to the Employees’ Profit Sharing Plan and Trust are made at the discretion of the Bancorp’s Board of Directors. Contributions for the years ended December 31, 2017 were based on 8% of the participants’ total compensation, excluding incentives, as compared to 9% for 2016. Profit sharing contributions made by the Bank and earnings credited to the employee’s account vest on the following schedule: two years of service, 40% of contributions and earnings; three years of service, 60% of contributions and earnings; four years of service, 80% of contributions and earnings; and five years of service, 100% of contributions and earnings. Participants also become 100% vested in the employer contributions and accrued earnings in their account upon their death, approved disability, or attainment of age 65 while employed at the Bank. The benefit plan expense amounted to approximately $796 thousand for 2017 and $843 thousand for 2016. The Bancorp maintains an Unqualified Deferred Compensation Plan (the “UDC Plan”). The purpose of the UDC Plan is to provide deferred compensation to key senior management employees of the Bancorp in order to recognize their substantial contributions to the Bank and provide them with additional financial security as inducement to remain with the Bank. The Compensation Committee selects which persons shall be participants in the UDC Plan. Participants’ accounts are credited each year with an amount based on a formula involving the participant’s employer funded contributions under all qualified plans and the limitations imposed by Internal Revenue Code subsection 401(a)(17) and Code section 415. The unqualified deferred compensation plan liability at December 31, 2017 and 2016 was approximately $211 thousand and $200 thousand, respectively. The UDC Plan expense amounted to approximately $6 thousand for 2017 and $13 thousand for 2016. Directors have deferred some of their fees in consideration of future payments. Fee deferrals, including interest, totaled approximately $68 thousand and $72 thousand for 2017 and 2016, respectively. The deferred fee liability at December 31, 2017 and 2016 was approximately $1.3 million and $1.4 million, respectively.

Banking and Thrift [Abstract]
Regulatory Capital Requirements under Banking Regulations [Text Block]	Note 11 – Regulatory Capital The Bancorp and Bank are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and prompt corrective action regulations involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet various capital requirements can initiate regulatory action. Prompt corrective action regulations provide five classifications, including well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. At December 31, 2017 and 2016, the most recent regulatory notifications categorized the Bancorp and Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the Bancorp’s or the Bank’s category. The following table shows that, at December 31, 2017, and December 31, 2016, the Bancorp’s capital exceeded all applicable regulatory capital requirements. The dollar amounts are in millions.

Under Indiana law, the Bank may pay dividends from its undivided profits (generally, earnings less losses, bad debts, taxes and other operating expenses) as is considered expedient by the Bank’s Board of Directors. However, the Bank must obtain the approval of the Indiana Department of Financial Institutions (DFI) if the total of all dividends declared by the Bank during the current year, including the proposed dividend, would exceed the sum of retained net income for the year to date plus its retained net income for the previous two years. For this purpose, “retained net income,” means net income as calculated for call report purposes, less all dividends declared for the applicable period. An exemption from DFI approval would require that the Bank have been assigned a composite uniform financial institutions rating of 1 or 2 as a result of the most recent federal or state examination; the proposed dividend would not result in a Tier 1 leverage ratio below 7.5%; and that the Bank not be subject to any corrective action, supervisory order, supervisory agreement, or board approved operating agreement. The aggregate amount of dividends that may be declared by the Bank in 2018, without the need for qualifying for an exemption or prior DFI approval, is $10.2 million plus 2018 net profits. Moreover, the FDIC and the Federal Reserve Board may prohibit the payment of dividends if it determines that the payment of dividends would constitute an unsafe or unsound practice in light of the financial condition of the Bank. On November 17, 2017 the Board of Directors of the Bancorp declared a fourth quarter dividend of $0.29 per share. The Bancorp’s fourth quarter dividend was paid to shareholders on January 9, 2018.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	Note 12 – Stock Based Compensation The Bancorp’s 2015 Stock Option and Incentive Plan (the “Incentive Plan”), which was adopted by the Bancorp’s Board of Directors on February 17, 2015 and approved by the Bancorp’s shareholders on April 24, 2015, permits the grant of equity awards for up to 250,000 shares of common stock. Awards granted under the Incentive Plan may be in the form of incentive stock options, non-qualified stock options, restricted stock, unrestricted stock, performance shares, or performance units. The purposes of the Plan are (i) to align the personal interests of plan participants with those of the shareholders of the Bancorp, (ii) to encourage key individuals to accept or continue employment or service with the Bancorp and its subsidiaries, and (iii) to furnish incentives to such key individuals to improve operations and increase profits by providing such key individuals the opportunity to acquire common stock of the Bancorp or to receive monetary payments based on the value of such common stock. Option awards are generally granted with an exercise price equal to the market price of the Bancorp’s common stock at the date of grant. No expense was charged against income for incentive stock options during 2017 or 2016. The fair value of each incentive stock option award is estimated on the date of grant using a closed form option valuation (Black-Scholes) model. Expected volatilities are based on historical volatilities of the Company’s common stock. No incentive stock options were granted during 2017 or 2016. The Bancorp uses historical data to estimate option exercise and post-vesting termination behavior. The expected term of options granted is based on historical data and represents the period of time that options granted are expected to be outstanding, which takes into account that the options are not transferable. The risk-free interest rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. A summary of the Bancorp’s stock option activity for 2017 and 2016 follows: Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term (Years) Aggregate Intrinsic Value Outstanding at January 1, 2016 750 $ 28.50 Granted - - Exercised - - Forfeited or expired (250 ) 28.50 Outstanding at end of year 500 $ 28.50 1.2 $ 5,175 Vested or expected to vest 500 $ 28.50 1.2 $ 5,175 Exercisable at December 31, 2016 500 $ 28.50 1.2 $ 5,175 Outstanding at January 1, 2017 500 $ 28.50 Granted - - Exercised (500 ) $ 28.50 Forfeited or expired - - Outstanding at end of year - $ - - $ - Vested or expected to vest - $ - - $ - Exercisable at December 31, 2017 - $ - - $ - As of December 31, 2017, there were no unrecognized compensation costs related to non-vested incentive stock options granted under the Incentive Plan. Restricted stock awards are generally granted with an award price equal to the market price of the Bancorp’s common stock on the award date. Restricted stock awards have been issued with a five year vesting period. Forfeiture provisions exist for personnel that separate employment before the vesting period expires. Compensation expense related to restricted stock awards is recognized over the vesting period. Total compensation cost that has been charged against income for those plans was approximately $192 thousand and $142 thousand for 2017 and 2016, respectively. A summary of changes in the Bancorp’s non-vested restricted stock for 2017 and 2016 follows: Non-vested Shares Shares Weighted Average Grant Date Fair Value Non-vested at January 1, 2016 19,725 $ 25.15 Granted 8,740 30.10 Vested - - Forefited - - Non-vested at December 31, 2016 28,465 $ 26.67 Non-vested at January 1, 2017 28,465 $ 26.67 Granted 4,575 39.00 Vested (1,625 ) 25.81 Forefited (725 ) 28.62 Non-vested at December 31, 2017 30,690 $ 28.51 As of December 31, 2017, there was approximately $400 thousand of total unrecognized compensation cost related to non-vested restricted shares granted under the Incentive Plan. The cost is expected to be recognized over a weighted-average period of 2.1 years.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	Note 15 – Commitments and Contingencies The Bancorp is a party to financial instruments in the normal course of business to meet the financing needs of its customers. These financial instruments, which include commitments to make loans and standby letters of credit, are not reflected in the accompanying consolidated financial statements. Such financial instruments are recorded when they are funded. The Bancorp’s exposure to credit loss in the event of non-performance by the other party to the financial instrument for commitments to originate loans and standby letters of credit is represented by the contractual amount of those instruments. Commitments generally have fixed expiration dates or other termination clauses and may require the payment of a fee. The Bancorp uses the same credit policy to make such commitments as it uses for on-balance sheet items. Since commitments to make loans may expire without being used, the amount does not necessarily represent future cash commitments. The Bancorp had outstanding commitments to originate loans as follows: (Dollars in thousands) Fixed Variable Rate Rate Total December 31, 2017: Residential real estate $ 70 $ 7,678 $ 7,748 Home equity 31,008 1,838 32,846 Commercial real estate 1,351 6,866 8,217 Construction and land development 8,074 21,105 29,179 Multifamily 174 322 496 Consumer 16,469 - 16,469 Commercial business 1,103 41,381 42,484 Government - - - Total $ 58,249 $ 79,190 $ 137,439 December 31, 2016: Residential real estate $ 82 $ 7,683 $ 7,765 Home equity 25,896 2,839 28,735 Commercial real estate 1,426 5,973 7,399 Construction and land development 5,838 8,029 13,867 Multifamily 6,168 192 6,360 Consumer 15,332 - 15,332 Commercial business 1,088 41,474 42,562 Government - - - Total $ 55,830 $ 66,190 $ 122,020 The approximately $58.2 million in fixed rate commitments outstanding at December 31, 2017 had interest rates ranging from 2.99% to 10.00%, for a period not to exceed forty-five days. At December 31, 2016, fixed rate commitments outstanding of approximately $55.8 million had interest rates ranging from 2.99% to 10.00%, for a period not to exceed forty-five days. Mortgage interest rate locks with borrowers which are included with real estate commitments, were treated as derivative transactions. Standby letters of credit are conditional commitments issued by the Bancorp to guarantee the performance of a customer to a third party. At December 31, 2017 and 2016, the Bancorp had standby letters of credit totaling approximately $9.9 million and $7.8 million, respectively which are not included in the tables above. The Bancorp evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Bancorp upon extension of credit, is based on management’s credit evaluation of the borrower. Collateral obtained may include accounts receivable, inventory, property, land or other assets.

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	Note 16 – Fair Values of Financial Instruments The Fair Value Measurements Topic (the “Topic”) establishes a hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The Topic describes three levels of inputs that may be used to measure fair value: Level 1: Level 2: Level 3: The fair values of securities available for sale are determined on a recurring basis by obtaining quoted prices on nationally recognized securities exchanges or pricing models utilizing significant observable inputs such as matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities, but rather by relying on the securities’ relationship to other benchmark quoted securities. Different judgments and assumptions used in pricing could result in different estimates of value. In certain cases where market data is not readily available because of lack of market activity or little public disclosure, values may be based on unobservable inputs and classified in Level 3 of the fair value hierarchy. At the end of each reporting period, securities held in the investment portfolio are evaluated on an individual security level for other-than-temporary impairment in accordance with the Investments – Debt and Equity Securities Topic. Impairment is other-than-temporary if the decline in the fair value of the security is below its amortized cost and it is probable that all amounts due according to the contractual terms of a debt security will not be received. Significant judgments are required in determining impairment, which include making assumptions regarding the estimated prepayments, loss assumptions and the change in interest rates. The Bancorp considers the following factors when determining other-than-temporary impairment for a security: the length of time and the extent to which the market value has been less than amortized cost; the financial condition and near-term prospects of the issuer; the underlying fundamentals of the relevant market and the outlook for such market for the near future; an assessment of whether the Bancorp (1) has the intent to sell the debt securities or (2) more likely than not will be required to sell the debt securities before their anticipated market recovery. If either of these conditions are met, management will recognize other-than-temporary impairment. If, in management’s judgment, an other-than-temporary impairment exists, the cost basis of the security will be written down for the credit loss, and the unrealized loss will be transferred from accumulated other comprehensive loss as an immediate reduction of current earnings. The Bancorp’s management utilizes a specialist to perform an other-than-temporary impairment analysis for each of its four pooled trust preferred securities. The analysis is performed semiannually on June 30 and December 31 and utilizes analytical models used to project future cash flows for the pooled trust preferred securities based on current assumptions for prepayments, default and deferral rates, and recoveries. The projected cash flows are then tested for impairment consistent with the Investments – Other Topic and the Investments – Debt and Equity Securities Topic. The other-than-temporary impairment testing compares the present value of the cash flows from quarter to quarter to determine if there is a “favorable” or “adverse” change. Other-than-temporary impairment is recorded if the projected present value of cash flows is lower than the book value of the security. To perform the semi-annual other-than-temporary impairment analysis, management utilizes current reports issued by the trustee, which contain principal and interest tests, waterfall distributions, note valuations, collection detail and credit ratings for each pooled trust preferred security. In addition, a detailed review of the performing collateral was performed. The review of the collateral began with a review of financial information provided by SNL Financial, a comprehensive database, widely used in the industry, which gathers financial data on banks and thrifts from U.S. GAAP financial statements for public companies (annual and quarterly reports on Forms 10-K and 10-Q), as well as regulatory reports for private companies, including consolidated financial statements for bank holding companies (FR Y-9C reports) and parent company-only financial statements for bank holding companies (FR Y-9LP reports) filed with the Federal Reserve and bank call reports filed with the FDIC and OCC. Using the information sources described above, for each bank and thrift examined, the following items were examined: nature of the issuer’s business, years of operating history, corporate structure, loan composition and loan concentrations, deposit mix, asset growth rates, geographic footprint and local economic environment. The issuers’ historical financial performance was reviewed and their financial ratios were compared to appropriate peer groups of regional banks or thrifts with similar asset sizes. The analysis focused on six broad categories: profitability (revenue streams and earnings quality, return on assets and shareholder’s equity, net interest margin and interest rate sensitivity), credit quality (charge-offs and recoveries, non-current loans and total non-performing assets as a percentage of total loans, loan loss reserve coverage and the adequacy of the loan loss provision), operating efficiency (noninterest expense compared to total revenue), capital adequacy (Tier-1, total capital and leverage ratios and equity capital growth), leverage (tangible equity as a percentage of tangible assets, short-term and long-term borrowings and double leverage at the holding company) and liquidity (the nature and availability of funding sources, net non-core funding dependence and quality of deposits). In addition, for publicly traded companies, stock price movements were reviewed and the market price of publicly traded debt instruments was examined. The current other-than-temporary impairment analysis indicated that the Bancorp’s four pooled trust preferred securities had no additional other-than-temporary impairment for the years ending December 31, 2017 and 2016. The table below shows the credit loss roll forward for the Bancorp’s pooled trust preferred securities that have been classified with other-than-temporary impairment: (Dollars in thousands) Collateralized debt obligations other-than-temporary impairment Ending balance, December 31, 2016 $ 271 Additions not previously recognized - Ending balance, December 31, 2017 $ 271 The following table contains information regarding the Bancorp’s pooled trust preferred securities as of December 31, 2017: Cusip 74043CAC1 74042TAJ0 01449TAB9 01450NAC6 Deal name PreTSL XXIV PreTSL XXVII Alesco IX Alesco XVII Class B-1 C-1 A-2A B Lowest credit rating assigned CCC CC BB CCC Number of performing banks 62 33 63 51 Number of performing insurance companies 13 7 10 n/a Number of issuers in default 16 7 2 4 Number of issuers in deferral 2 2 1 1 Defaults & deferrals as a % of performing collateral 26.56 % 20.06 % 2.93 % 8.11 % Subordination: As a % of performing collateral 23.55 % 8.35 % 53.11 % 35.58 % As a % of performing collateral - adjusted for projected future defaults 18.67 % 1.24 % 49.64 % 31.69 % Other-than-temporary impairment model assumptions: Defaults: Year 1 - issuer average 2.00 % 2.40 % 2.30 % 1.90 % Year 2 - issuer average 2.00 % 2.40 % 2.30 % 1.90 % Year 3 - issuer average 2.00 % 2.40 % 2.30 % 1.90 % > 3 Years - issuer average (1 ) (1 ) (1 ) (1 ) Discount rate - 3 month Libor, plus implicit yield spread at purchase 1.48 % 1.23 % 1.27 % 1.44 % Recovery assumptions (2 ) (2 ) (2 ) (2 ) Prepayments 0.00 % 0.00 % 0.00 % 0.00 % Other-than-temporary impairment $ 41 $ 132 $ 36 $ 62 (1) - Default rates > 3 years are evaluated on a issuer by issuer basis and range from 0.25% to 5.00%. (2) - Recovery assumptions are evaluated on a issuer by issuer basis and range from 0% to 15% with a five year lag. In the table above, the Bancorp’s subordination for each trust preferred security is calculated by taking the total performing collateral and subtracting the sum of the total collateral within the Bancorp’s class and the total collateral within all senior classes, and then stating this result as a percentage of the total performing collateral. This measure is an indicator of the level of collateral that can default before potential cash flow disruptions may occur. In addition, management calculates subordination assuming future collateral defaults by utilizing the default/deferral assumptions in the Bancorp’s other-than-temporary impairment analysis. Subordination assuming future default/deferral assumptions is calculated by deducting future defaults from the current performing collateral. At December 31, 2017 and 2016, management reviewed the subordination levels for each security in context of the level of current collateral defaults and deferrals within each security; the potential for additional defaults and deferrals within each security; the length of time that the security has been in “payment in kind” status; and the Bancorp’s class position within each security. Management calculated the other-than-temporary impairment model assumptions based on the specific collateral underlying each individual security. The following assumption methodology was applied consistently to each of the four pooled trust preferred securities: For collateral that has already defaulted, no recovery was assumed; no cash flows were assumed from collateral currently in deferral, with the exception of the recovery assumptions. The default and recovery assumptions were calculated based on the detailed collateral review. The discount rate assumption used in the calculation of the present value of cash flows is based on the discount margin (i.e., credit spread) at the time each security was purchased using the original purchase price. The discount margin is then added to the appropriate 3-month LIBOR forward rate obtained from the forward LIBOR curve. At December 31, 2017 and 2016, three of the trust preferred securities with a cost basis of $3.5 million have been placed in “payment in kind” status. The Bancorp’s securities that are classified as “payment in kind” are a result of not receiving the scheduled quarterly interest payments. For the securities in “payment in kind” status, management anticipates to receive the unpaid contractual interest payments from the issuer, because of the self-correcting cash flow waterfall provisions within the structure of the securities. When a tranche senior to the Bancorp’s position fails the coverage test, the Bancorp’s interest cash flows are paid to the senior tranche and recorded as a reduction of principal. The coverage test represents an over collateralization target by stating the balance of the performing collateral as a percentage of the balance of the Bancorp’s tranche, plus the balance of all senior tranches. The principal reduction in the senior tranche continues until the appropriate coverage test is passed. As a result of the principal reduction in the senior tranche, more cash is available for future payments to the Bancorp’s tranche. Consistent with the Investments – Debt and Equity Securities Topic, management considered the failure of the issuer of the security to make scheduled interest payments in determining whether a credit loss existed. Management will not capitalize the “payment in kind” interest payments to the book value of the securities and will keep these securities in non-accrual status until the quarterly interest payments resume. Assets and Liabilities Measured at Fair Values on a Recurring Basis There were no transfers to or from Levels 1 and 2 during the years ended December 31, 2017 and 2016. Changes in Level 3 assets are solely the result of changes in estimated fair values of securities that have been classified as level 3 during all of 2017 and 2016.

Appraisals may utilize a single valuation approach or a combination of approaches, including comparable sales and the income approach. The recorded investment of impaired loans was approximately $2.5 million and the related specific reserves totaled approximately $704 thousand, resulting in a fair value of impaired loans totaling approximately $1.8 million, at December 31, 2017. The recorded investment of impaired loans was approximately $3.5 million and the related specific reserves totaled approximately $1.2 million, resulting in a fair value of impaired loans totaling approximately $2.3 million, at December 31, 2016. Fair value is determined, where possible, using market prices derived from an appraisal or evaluation, which are considered to be Level 2 inputs. However, certain assumptions and unobservable inputs are often used by the appraiser, therefore, qualifying the assets as Level 3 in the fair value hierarchy. The fair value of foreclosed real estate is similarly determined by using the results of recent real estate appraisals. The numerical range of unobservable inputs for these valuation assumptions is not meaningful to this presentation. The following table shows carrying values and related estimated fair values of financial instruments as of the dates indicated. Estimated fair values are further categorized by the inputs used to measure fair value. Items that are not financial instruments are not included.

Certificates of deposits in other financial institutions carrying amounts approximate fair value (Level 2). The fair values of securities available-for-sale are obtained from broker pricing (Level 2), with the exception of collateralized debt obligations, which are valued by a third-party specialist (Level 3). Loans held-for-sale comprise residential mortgages and are priced based on values established by the secondary mortgage markets (Level 1). The estimated fair value for net loans receivable is based on estimates of the rate the Bancorp would charge for similar such loans, applied for the time period until estimated repayment, in addition to appraisals which may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach (Level 3). Federal Home Loan Bank stock is estimated at book value due to restrictions that limit the sale or transfer of the security. Fair values of accrued interest receivable and payable approximate book value, as the carrying values are determined using the observable interest rate, balance, and last payment date. Non-interest and interest bearing deposits, which include checking, savings, and money market deposits, are estimated to have fair values based on the amount payable as of the reporting date (Level 1). The fair value of fixed-maturity certificates of deposit (included in interest bearing deposits) are based on estimates of the rate the Bancorp would pay on similar deposits, applied for the time period until maturity (Level 2). Estimated fair values for short-term repurchase agreements, which represent sweeps from demand deposits to accounts secured by pledged securities, are estimated based on the amount payable as of the reporting date (Level 1). Longer-term repurchase agreements, with contractual maturity dates of three months or more, are based on estimates of the rate the Bancorp would pay on similar deposits, applied for the time period until maturity (Level 2). Short-term borrowings are generally only held overnight, therefore, their carrying amount is a reasonable estimate of fair value (Level 1). The fair value of FHLB Advances are estimated by discounting the future cash flows using quoted rates from the FHLB for similar advances with similar maturities (Level 2). The estimated fair value of other financial instruments, and off-balance sheet loan commitments, approximate cost and are not considered significant to this presentation.

Marketable Securities, Policy [Policy Text Block]	Securities The Bancorp considers the following factors when determining an other-than-temporary impairment for a security: the length of time and the extent to which the market value has been less than amortized cost; the financial condition and near-term prospects of the issuer; the underlying fundamentals of the relevant market and the outlook for such market for the near future; and an assessment of whether the Bancorp has (1) the intent to sell the debt security or (2) it is more likely than not that the Bancorp will be required to sell the debt security before its anticipated market recovery. If either of these conditions are met, management will recognize other-than-temporary impairment. If, in management’s judgment, an other-than-temporary impairment exists, the cost basis of the security will be written down for the credit loss, and the unrealized credit loss will be transferred from accumulated other comprehensive loss as an immediate reduction of current earnings.
Finance, Loan and Lease Receivables, Held-for-sale, Policy [Policy Text Block]	Loans Held-for-Sale Mortgage loans held-for-sale can be sold with servicing rights retained or released. The carrying value of mortgage loans sold is reduced by the amount allocated to the servicing rights. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold.
Loans And Loan Income [Policy Text Block]	Loans and Loan Income The accrual of interest income on mortgage and commercial loans is discontinued at the time the loan is 90 days delinquent unless the loan is well-secured and in process of collection. Consumer loans are typically charged-off no later than when they reach 120 days past due. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on non-accrual or charged-off status at an earlier date if collection of principal or interest is considered doubtful. Generally, interest accrued but not received for loans placed on non-accrual status is reversed against interest income. Interest received on such 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.
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	Allowance for Loan Losses A loan is considered impaired when, based on current information and events, it is probable that the Bancorp 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 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. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Bancorp does not separately identify individual consumer and residential loans for impairment disclosures.
Loans and Leases Receivable, Troubled Debt Restructuring Policy [Policy Text Block]	Troubled Debt Restructures Some of the factors considered by management when determining whether a borrower is experiencing financial difficulties are: (1) is the borrower currently in default on any of its debts, (2) has the borrower declared or is the borrower in the process of declaring bankruptcy, and (3) absent the current modification, the borrower would likely default.
