Nature of Operations and Summary of Significant Accounting Policies [Abstract]
Nature of Operations and Summary of Significant Accounting Policies	Note 1: Nature of Operations and Summary of Significant Accounting Policies The accounting and reporting policies of MutualFirst Financial, Inc. (Company) and its wholly owned subsidiar ies , MFBC Statutory Trust I , MutualFirst Risk Management, Inc., Mutual Risk Advisors, Inc., and MutualBank (Bank) and the Bank’s wholly owned subsidiaries, Mishawaka Financial Services , Inc. , Mutual Federal Investment Company and the wholly owned subsidiary of Mutual Federal Investment Company, Mutual Federal REIT, Inc. and Summit Service Corp. and their wholly owned subsidiary, Summit Mortgage, Inc., conform to accounting principles generally accepted in the United States of America and reporting practices followed by the banking industry. The more significant of the policies are described below. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, goodwill, valuation of real estate acquired in connection with foreclosures or in satisfaction of loans, loan servicing rights, valuation of deferred tax assets, other-than-temporary impairments (OTTI) and fair value of financial instruments. The Bank generates mortgage, consumer and commercial loans and receives deposits from customers located primarily in North and Central Indiana. The Bank’s loans are generally secured by specific items of collateral including real property, consumer assets and business assets. Mutual Federal Investment Company invests in various investment securities and loans through Mutual Federal REIT, Inc. Consolidation - The consolidated financial statements include the accounts of the Company, the Bank, and the Bank’s subsidiaries, after elimination of all material intercompany transactions. Cash Equivalents - The Company considers all liquid investments with original maturities of three months or less to be cash equivalents. At December 31, 201 7 and 201 6 , cash equivalents consisted primarily of money market accounts with brokers and checking accounts with government sponsored entities. At December 31, 201 7 , the Company’s cash accounts exceeded federally insured limits by approximately $ 6.1 million . Included in this amount are uninsured accounts of approximately $ 2.6 million at the Federal Reserve Bank of Chicago and Federal Home Loan Bank of Indianapolis . Interest-bearing time deposits – The fair value of interest-bearing time deposits approximates carrying value. Derivative Instruments – The Company occasionally enters into derivative financial instruments as part of its interest rate risk strategies. These derivative financial instruments consist primarily of interest rate swaps. These instruments are carried at the fair value of the derivatives and reflects the estimated amounts that would have been received to terminate these contracts at the reporting date based upon pricing or valuation models applied to current market information.  The Company offers interest rate derivative products (e.g. interest rate swaps) to certain of its high-quality commercial borrowers. This product allows customers to enter into an agreement with the Company to swap their variable rate loan to a fixed rate. These derivative products are designed to reduce, eliminate or modify the risk of changes in the borrower’s interest rate. The extension of credit incurred through the execution of these derivative products is subject to the same approvals and rigorous underwriting standards as the related traditional credit product. The Company limits its risk exposure to these products by entering into a mirror-image, offsetting swap agreement with a separate, well-capitalized and rated counterparty. These transactions are ratified by the Asset Liability Committee. By using these interest rate swap arrangements, the Company is also better insulated from the interest rate risk associated with underwriting fixed-rate loans. These derivative products do not qualify for hedge accounting. The derivatives are recorded on the balance sheet at fair value and changes in fair value of both the customer and the offsetting swap agreements are recorded (and essentially offset) in non-interest income.  Investment Securities - Certain debt securities that management has the positive intent and ability to hold to maturity are classified as “held to maturity” and recorded at amortized cost . At December 31, 2017 and 2016, no securities were classified as held to maturity . Securities not classified as held to maturity, including equity securities with readily determinable fair values, are classified as “available for sale” and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income , net of tax . Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. When the Company does not intend to sell a debt security, and it is more likely than not the Company will not have to sell the security before recovery of its cost basis, it recognizes the credit component of an other-than-temporary impairment of a debt security in earnings and the remaining portion in other comprehensive income. For held to maturity debt securities, the amount of an other-than-temporary impairment recorded in other comprehensive income for the noncredit portion of a previous other-than-temporary impairment is amortized prospectively over the remaining life of the security on the basis of the timing of future estimated cash flows of the security. T he Company’s consolidated statement of income reflects the full impairment (that is, the difference s between the security’s amortized cost basis and fair value) on debt securities that the Company intends to sell or would more likely than not be required to sell before the expected recovery of the amortized cost basis. For available for sale and held to maturity debt securities that management has no intent to sell and believes that it more likely than not will not be required to sell prior to recovery, only the credit loss component of the impairment is recognized in earnings, while the noncredit loss is recognized in accumulated other comprehensive income. The credit loss component recognized in earnings is identified as the amount of principal cash flows not expected to be received over the remaining term of the security as projected based on cash flow projections. For equity securities, when the Company has decided to sell an impaired available for sale security and does not expect the fair value of the security to fully recover before the expected time of sale, the security is deemed other-than-temporarily impaired in the period in which the decision to sell is made. The Company recognizes an impairment loss when the impairment is deemed other than temporary even if a decision to sell has not been made. Declines in the fair value of securities below their cost that are other-than-temporary are reflected as realized losses. In estimating other-than-temporary losses, management considers the length of time and extent that fair value has been less than cost, the financial condition and near - term prospects of the issuer, and the Company’s ability and intent to hold the security for a period sufficient to allow for any anticipated recovery in fair value. Loans held for sale are carried at the lower of aggregate cost or market. Market is determined using the aggregate method. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income based on the difference between estimated sales proceeds and aggregate cost. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoffs are reported at their outstanding principal balances adjusted for unearned income, charge-offs, the allowance for loan losses, any unamortized deferred fees or costs on originated loans and unamortized premiums or discounts on purchased loans. For loans amortized at cost, interest income is accrued based on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, as well as premiums and discounts, are deferred and amortized as a level yield adjustment over the respective term of the loan. The accrual of interest on mortgage , consumer and commercial loans is discontinued at the time the loan is 90 days past due unless the credit is well-secured and in process of collection. Past due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date if collection of 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. Discounts and premiums on purchased residential real estate and commercial loans is amortized to income using the interest method over the remaining period to contractual maturity, adjusted for anticipated prepayments. Discounts and premiums on purchased consumer loans are recognized over the expected lives of the loans using methods that approximate the interest method. 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 income. Loan losses are charged against the allowance when management believes the inability to collect a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. We maintain an allowance for loan losses to absorb losses inherent in the loan portfolio. The allowance is based on ongoing, quarterly assessments of the estimated losses inherent in the loan portfolio. Our methodology for assessing the appropriateness of the allowance consists of several key elements, including the general allowance and specific allowances for identified problem loans and portfolio segments. In addition, the allowance incorporates the results of measuring impaired loans as provided in ASC 310, Receivables . These accounting standards prescribe the measurement methods, income recognition and disclosures related to impaired loans. The general allowance is calculated by applying loss factors to outstanding loans based on the internal risk evaluation of such loans or pools of loans. Changes in risk evaluations of both performing and nonperforming loans affect the amount of the general allowance. Loss factors are based on our historical loss experience as well as on significant factors that, in management’s judgment, affect the collectability of the portfolio as of the evaluation date. The historical loss experience is determined by portfolio segment and is based on the actual loss history experienced by the Company over the prior three years. Management believes the three year historical loss experience methodology is appropriate in the current economic environment, as it captures loss rates that are comparable to the current period being analyzed. The appropriateness of the allowance is reviewed by management based upon its evaluation of then-existing economic and business conditions affecting our key lending areas and other conditions, such as credit quality trends (including trends in non-performing loans expected to result from existing conditions), collateral values, loan volumes and concentrations, specific industry conditions within portfolio segments and recent loss experience in particular segments of the portfolio that existed as of the balance sheet date and the impact that such conditions were believed to have had on the collectability of the loan. Senior management reviews these conditions quarterly in discussions with our senior credit officers. To the extent that any of these conditions is evidenced by a specifically identifiable problem credit or portfolio segment as of the evaluation date, management’s estimate of the effect of such condition may be reflected as a specific allowance applicable to such credit or portfolio segment. Where any of these conditions is not evidenced by a specifically identifiable problem credit or portfolio segment as of the evaluation date, management’s evaluation of the loss related to this condition is reflected in the general allowance for loan losses. The evaluation of the inherent loss with respect to these conditions is subject to a higher degree of uncertainty because they are not identified with specific problem credits or portfolio segments. The allowance for loan losses is based on estimates of losses inherent in the loan portfolio. Actual losses can vary significantly from the estimated amounts. Our methodology as described permits adjustments to any loss factor used in the computation of the general allowance in the event that, in management’s judgment, significant factors which affect the collectability of the portfolio as of the evaluation date are not reflected in the loss factors. By assessing the probable incurred losses inherent in the loan portfolio on a quarterly basis, we are able to adjust specific and inherent loss estimates based upon any more recent information that has become available. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the ability to collect 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 allocated and general components. The allocated component relates to loans that are classified as impaired. For those loans that are 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 charge-off experience and expected loss given default derived from the Company’s internal risk rating process. Other adjustments may be made to the allowance for pools of loans after an assessment of internal or external influences on credit quality that are not fully reflected in the historical loss or risk rating data. A loan is considered impaired when, based on current information and events, it is probable that the Company 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. Groups of loans with similar risk characteristics are collectively evaluated for impairment based on the group’s historical loss experience adjusted for changes in trends, conditions and other relevant factors that affect repayment of the loans. Accordingly, the Company does not separately identify individual consumer and residential loans for impairment measurements, unless such loans are the subject of a restructuring agreement due to financial difficulties of the borrower. Premises and equipment are carried at cost net of accumulated depreciation. Depreciation is computed using the straight-line method based principally on the estimated useful lives of the assets which range from 3 to 4 0 years. Maintenance and repairs are expensed as incurred while major additions and improvements are capitalized. Gains and losses on dispositions are included in current operations. Federal Home Loan Bank stock is a required investment for institutions that are members of the Federal Home Loan Bank (FHLB) system. The required investment in the common stock is based on a predetermined formula , carried at cost and is evaluated for impairment . Mortgage-servicing assets are recognized separately when rights are acquired through purchase or through sale of financial assets. Under the servicing assets and liabilities accounting guidance , servicing rights resulting from the sale or securitization of loans originated by the Company are initially measured at fair value at the date of transfer. The Company subsequently measures each class of servicing asset using the amortization method. Under the amortization method, servicing rights are amortized in proportion to and over the period of estimated net servicing income. The amortized assets are assessed for impairment based on fair value at each reporting date. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. These variables change from quarter to quarter as market conditions and projected interest rates change, and may have an adverse impact on the value of the mortgage servicing right and may result in a reduction to noninterest income. Each class of separately recognized servicing assets subsequently measured using the amortization method are evaluated and measured for impairment. Impairment is determined by stratifying rights into tranches based on predominant characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual tranche, to the extent that fair value is less than the carrying amount of the servicing assets for that tranche. The valuation allowance is adjusted to reflect changes in the measurement of impairment after the initial measurement of impairment. Changes in valuation allowances are reported with net servicing fees on the income statement. Fair value in excess of the carrying amount of servicing assets for that stratum is not recognized. Servicing fee income is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. The amortization of mortgage servicing rights is netted against loan servicing fee income. Intangible assets are being amortized on an accelerated basis over periods ranging from three to 11 years. Such assets are periodically evaluated as to the recoverability of their carrying value. Income tax es are account ed for in accordance with income tax accounting guidance. The income tax accounting guidance results in two components of income tax expense: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Company determines deferred income taxes using the balance shee t method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred tax assets are evaluated on a quarterly basis for recoverability based on all available evidence. This process involves significant management judgment about assumptions that are subject to change from period to period based on changes in tax laws or variances between our future projected operating performance and our actual results. We are required to establish a valuation allowance for deferred tax assets if we determine, based on available evidence at the time the determination is made, that it is more likely than not that some portion or all of the deferred tax assets will not be realized. In determining the more-likely-than-not criterion, we evaluate all positive and negative available evidence as of the end of each reporting period. Future adjustments to the deferred tax asset valuation allowance, if any, will be determined based upon changes in the expected realization of the net deferred tax assets. The realization of the deferred tax assets ultimately depends on the existence of sufficient taxable income in either the carry back or carry forward periods under applicable tax laws. Due to significant estimates utilized in establishing the valuation allowance and the potential for changes in facts and circumstances, it is reasonably possible that we will be required to record adjustments to the valuation allowance in the near term if estimates of future taxable income during the carry forward period are reduced. Such a charge could have a material adverse effect on our results of operations, financial condition, and capital position. Uncertain tax positions are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more likely than not means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances and information available at the reporting date and is subject to management’s judgment. The Company recognizes interest and penalties on income taxes as a component of income tax expense. T he Company files consolidated income tax returns with its subsidiaries. Earnings per share is computed based upon the weighted-average common and common equivalent shares outstanding during each year. Comprehensive income consists of net income and other comprehensive income, net of applicable income taxes. Other comprehensive income includes unrealized gains (losses) on available for sale securities, unrealized gains (losses) on available for sale securities for which a portion of an other-than-temporary impairment has been recognized in income, unrealized and realized gains and losses in derivative financial instruments and changes in the funded status of defined benefit pension plans.

Impact of Accounting Pronouncements [Abstract]
Impact of Accounting Pronouncements	Note 2: Impact of Accounting Pronouncements  In February 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 201 8 -0 2, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, provides f inancial statement preparers with an option to reclassify stranded tax effects within AOCI to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act (or portion thereof) is recorded. The amendments are effective for all organizations for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The Company has assessed ASU 2018-02 and does not expect it to have a material impact on the Company’s accounting and disclosures.  In March 2017, the FASB issued Accounting Standards Update (“ASU”) 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The ASU shortens the amortization period for certain callable debt securities held at a premium and requires the premium to be amortized to the earliest call date. However, the amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The amendments are effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods. Early adoption is permitted. The Company early adopted this ASU in the first quarter of 2017 and it did not have a material impact on the Company’s consolidated financial statements.  In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350)-Simplifying the Test for Goodwill Impairment. These amendments eliminate Step 2 from the goodwill impairment test. The amendments also eliminate the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The guidance is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim goodwill impairment tests performed on testing dates after January 1, 2017. ASU 2017-04 should be adopted on a prospective basis. The Company has assessed ASU 2017-04 and does not expect it to have a material impact on its accounting and disclosures.  In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805)-Clarifying the Definition of a Business. ASU 2017-01 provides amendments to clarify the definition of a business and affect all companies and other reporting organizations that must determine whether they have acquired or sold a business. The amendments are intended to help companies and other organizations evaluate whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The guidance is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years and should be applied prospectively as of the beginning of the period of adoption. Early adoption is permitted under certain circumstances. The Company adopted ASU 2017-01 on January 1, 2018 and it did not have an impact on its accounting and disclosures.  In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The ASU is intended to address diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows by specifically addressing eight specific areas. The amendments are effective for the Company for annual and interim periods beginning in the first quarter of 2018. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating the effects that this ASU will have on its financial statements, specifically the Statement of Cash Flows, and does not expect these effects to be material.  In June 2016, the Financial Accounting Standards Board (FASB) issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Statements. Topic 326 amends guidance on reporting credit losses for assets held at amortized cost basis and available for sale debt securities. The ASU is intended to provide financial statement users with useful information about the expected credit losses on financial instruments and other commitments to extend credit.  · The ASU requires financial assets measured at amortized cost (primarily loans) be presented at the amount net of a valuation allowance for credit losses, and that the income statement include the measurement of credit losses for newly recognized financial assets as well as changes in expected losses on previously recognized financial assets. The provisions of this ASU does not specify the method for measuring expected credit losses, and an entity is allowed to apply methods that reasonably reflect its expectations of the credit loss estimate. The new model will be based on relevant information including past events, historical experience, current conditions, and reasonable and supportive forecasts that affect the collectability of the asset. The provisions of this ASU differ from current U.S. generally accepted accounting principles (“GAAP”) in that current U.S. GAAP generally delays recognition of the full amount of credit losses until the loss is probable of occurring. · This ASU requires that credit losses on available for sale debt securities be presented as an allowance rather than as a write-down.  This ASU will be effective for the Company for interim and annual periods beginning in the first quarter of 2020. Earlier adoption is permitted beginning in the first quarter of 2019. The Company is in the evaluation stage for this ASU in order to determine the most appropriate method of implementation and all resources and data (both current and historical) needed. In March 2016, the FASB issued ASU 2016-09, Compensation–Stock Compensation: Improvements to Employee Share-Based Payment Accounting. The amendments are intended to improve the accounting for employee share-based payments and affect all organizations that issue share-based payment awards to their employees. This Update includes amendments that currently apply, or may apply in the future, to the Company related to the following: (1) accounting for the difference between the deduction for tax purposes and the amount of compensation cost recognized for financial reporting purposes; (2) classification of excess tax benefits on the statement of cash flows; (3) accounting for forfeitures; (4) accounting for awards partially settled in cash in excess of the employer’s minimum statutory tax withholding requirements; and (5) classification of employee taxes paid on the statement of cash flows when an employer withholds shares for tax-withholding purposes. The amendments in this Update were effective for the Company for annual and interim periods beginning in the first quarter 2017. The ASU provides separate transition provisions for each of the amendments. Initial adoption of this ASU in 2017 did not have a material impact on the Company.  In February 2016, the FASB issued ASU 2016-02, Leases. The objective of the amendment is to establish the principles that lessees and lessors shall apply to report useful information to users of financial statements about the amount, timing, and uncertainty of cash flows arising from a lease. These changes will increase transparency among companies by recognizing lease assets and liabilities on the balance sheet and disclosing additional information about lease arrangements. The amendments in this update are effective for annual and interim periods beginning in the first quarter of 2019. The Company has operating leases in place for some locations as well as equipment and is in the early stages of evaluating the potential impact of adopting this amendment. In January 2016, the FASB issued ASU 2016-01, Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this Update require: (1) all equity investments to be measured at fair value with changes in the fair value recognized through net income (other than those accounted for under equity method of accounting or those that result in consolidation of the investee); (2) an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments; and (3) eliminates the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet for public business entities. The new guidance is effective for the Company for annual and interim periods beginning in the first quarter of 2018. The adoption of ASU 2016-01 is not anticipated to have a material effect on the Company’s consolidated financial statements.  In March 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers . This ASU states 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. This ASU affects entities that enter into contracts with customers to transfer goods or services or enter into contracts for the transfer of nonfinancial assets, unless those contracts are within the scope of other standards. In August 2015, the FASB issued ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date," which deferred the effective date of ASU 2014-09 for public entities to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. The Company’s revenue is comprised of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASU 2014-09, and non-interest income. We have completed our evaluation of the impact of ASU 2014-09 on components of our non-interest income including trust and investment management fees, insurance commissions and fees and have not found any significant changes to our methodology of recognizing revenue. As required by the ASU, we will adopt the standard in the first quarter of 2018 and, at the time of this filing, we do not anticipate recording a cumulative effect adjustment to opening retained earnings because the adjustment was determined to be insignificant. We will include newly applicable revenue disclosures on the Company’s Form 10-Q for the quarter ended March 31, 2018.

Investment Securities	 Note 4: I nvestment Securities The amortized costs and approximate fair values, together with gross unrealized gains and losses on securities, are as follows:    December 31, 2017  Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value  Available for Sale Securities  Mortgage-backed securities $ 68,335 $ 225 $ (762) $ 67,798  Collateralized mortgage obligations 88,488 58 (1,296) 87,250  Municipal obligations 107,060 3,709 (274) 110,495  Corporate obligations 12,966 69 (1,200) 11,835  Total investment securities $ 276,849 $ 4,061 $ (3,532) $ 277,378      December 31, 2016  Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value  Available for Sale Securities  Mortgage-backed securities $ 92,871 $ 802 $ (1,156) $ 92,517  Collateralized mortgage obligations 68,621 269 (843) 68,047  Municipal obligations 77,474 1,716 (1,508) 77,682  Corporate obligations 12,822 78 (1,233) 11,667  Total investment securities $ 251,788 $ 2,865 $ (4,740) $ 249,913  All mortgage-backed securities and collateralized-mortgage obligations held by the Company as of December 31, 201 7 were in government - sponsored and federal agency securities. Certain investments in debt securities are reported in the financial statements at an amount less than their historical cost. Total fair value of these investments at December 31, 201 7 and 201 6 was $ 142.9 million and $ 143.8 million, which is approximately 5 1.5 % and 57.6 % of the Company’s investment portfolio at those dates. While the federal funds rate increased fifty basis points in 2017, the longer end of the yield curve has remained relatively flat allowing for minimal change in the fair value of securities. Based on our evaluation of available evidence, including recent changes in market interest rates, management believes the fair value for the securities at less than historical cost for the periods presented are temporary. Should the impairment of any of these securities become other - than - temporary, the cost basis of the investment will be reduced and the resulting loss recognized in net income in the period the other-than-temporary impairment is identified. During 2017 and 2016, the Bank determined that its security holdings had no other-than-temporary impairment. The following tables show the gross unrealized losses and fair value of the Company’s investments , aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position at December 31, 201 7 and 201 6 :     December 31, 2017  Less than 12 Months 12 Months or More Total  Fair Value Unrealized Losses Fair Value Unrealized Losses Fair Value Unrealized Losses  Available for Sale Securities  Mortgage-backed securities $ 21,975 $ (127) $ 27,675 $ (635) $ 49,650 $ (762)  Collateralized mortgage obligations 47,153 (400) 28,887 (896) 76,040 (1,296)  Municipal obligations 4,479 (64) 10,041 (210) 14,520 (274)  Corporate obligations - - 2,722 (1,200) 2,722 (1,200)  Total temporarily impaired securities $ 73,607 $ (591) $ 69,325 $ (2,941) $ 142,932 $ (3,532)      December 31, 2016  Less than 12 Months 12 Months or More Total  Fair Value Unrealized Losses Fair Value Unrealized Losses Fair Value Unrealized Losses  Available for Sale Securities  Mortgage-backed securities $ 58,056 $ (1,156) $ - $ - $ 58,056 $ (1,156)  Collateralized mortgage obligations 41,769 (683) 4,688 (160) $ 46,457 $ (843)  Municipal obligations 31,907 (1,507) 337 (1) 32,244 (1,508)  Corporate obligations - - 7,076 (1,233) 7,076 (1,233)  Total temporarily impaired securities $ 131,732 $ (3,346) $ 12,101 $ (1,394) $ 143,833 $ (4,740)   Mortgage-Backed Securities (MBS) and Collateralized Mortgage Obligations (CMO) The unrealized losses on the Company’s investment in CMOs and MBSs were caused by interest rate changes and illiquidity . The Company expects to recover the amortized cost basis over the term of the securities. Because (1) the decline in market value is attributable to changes in interest rates and illiquidity and not credit quality, (2) the Company does not intend to sell the investments and (3) it is more likely than not the Company will not be required to sell the investments before recovery of their amortized cost bases, which may be at maturity, the Company does not consider these investments to be other-than-temporarily impaired at December 31, 201 7 . Municipal Obligations The unrealized losses on the Company’s investments in securities of state and political subdivisions were caused by changes in interest rates and illiquidity . The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the par value of the investments. The Company does not intend to sell the investment and it is not more likely than not that the Company will not be required to sell the se investment s. The Co mpany does not consider any of the se investment securities to be other-than-temporarily impaired at December 31, 2017 . Corporate Obligations The Company’s unrealized loss on investments in corporate obligations primarily relates to investments in pooled trust preferred securities. The unrealized losses were primarily caused by ( 1 ) a decrease in performance and regulatory capital resulting from exposure to subprime mortgages and ( 2 ) a sector downgrade by several industry analysts. Other-Than-Temporary Impairment Upon acquisition of a security, the Company decides whether it is within the scope of the accounting guidance for beneficial interests in securitized financial assets or whether it will be evaluated for impairment under the accounting guidance for investments in debt and equity securities. The accounting guidance for beneficial interests in securitized financial assets provides incremental impairment guidance for a subset of the debt securities within the scope of the guidance for investments in debt and equity securities. For securities that are a beneficial interest in securitized financial assets, the Company uses the beneficial interests in securitized financial asset impairment model. For securities that are not a beneficial interest in securitized financial assets, the Company uses debt and equity securities impairment model. The Company conducts periodic reviews to identify and evaluate each investment security to determine whether an other-than-temporary impairment has occurred. Economic models are used to determine whether an other-than-temporary impairment has occurred on these securities. While all securities are considered, the securities primarily impacted by other-than-temporary impairment testing are private-label mortgage-backed securities and trust preferred securities . The Bank’s trust preferred securities valuation was prepared by an independent third party. Their approach to determining fair value involved several steps including: · Detailed credit and structural evaluation of each piece of collateral in the trust preferred securities; · Collateral performance projections for each piece of collateral in the trust preferred security; · Terms of the trust preferred structure, as laid out in the indenture; and · Discounted cash flow modeling.  The Company uses market-based yield indicators as a baseline for determining appropriate discount rates, and then adjusts the resulting discount rates on the basis of its credit and structural analysis of specific trust preferred securities. The primary focus is on the returns a fixed income investor would require in order to allocate capital on a risk adjusted basis. There is currently no active market for pooled trust preferred securities; however, the Company looks principally to market yields for stand-alone trust preferred securities issued by banks, thrifts and insurance companies for which there is an active and liquid market. The next step is to make a series of adjustments to reflect the differences that exist between these products (both credit and structural) and, most importantly, to reflect idiosyncratic credit performance differences (both actual and projected) between these products and the underlying collateral in the specific trust preferred security. Importantly, as part of the analysis described above, MutualFirst considers the fact that structured instruments frequently exhibit leverage not present in stand-alone instruments, and make s adjustments as necessary to reflect this additional risk. The default and recovery probabilities for each piece of collateral were formed based on the evaluation of the collateral credit and a review of historical industry default data and current/near-term operating conditions. For collateral that has already defaulted, the Company assumed no recovery. For collateral that was in deferral, the Company assumed a recovery of 10% of par for banks, thrifts or other depository institutions and 15% of par for insurance companies. Although the Company conservatively assumed that the majority of the deferring collateral continues to defer and eventually defaults, we also recognize there is a possibility that some deferring collateral may become current at some point in the future. Credit Losses Recognized on Investments Certain debt securities have experienced fair value deterioration due to credit losses, as well as due to other market factors, but are not otherwise other-than-temporarily impaired. The amortized cost and fair value of securities available for sale at December 31, 201 7 , by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties.    Available for Sale  Description of Securities Amortized Cost Fair Value  Security obligations due  Within one year $ 160 $ 158  One to five years 5,001 5,034  Five to ten years 24,044 25,175  After ten years 90,821 91,963  120,026 122,330  Mortgage-backed securities 68,335 67,798  Collateralized mortgage obligations 88,488 87,250  Totals $ 276,849 $ 277,378  The Company did no t have securities pledged as collateral, to secure public deposits or for other purposes as of December 31, 201 7 or 201 6 .  Proceeds from sales of securities available for sale during 201 7 , 201 6 and 201 5 were $ 3 4.6 million, $57.0 million and $23.1 million, respectively . Gross gains of $776,000 , $ 1.1 million and $ 436,000 in 201 7 , 201 6 and 201 5 were recognized o n those sales. Gross losses of $68,000 and $ 71,000 in were recognized on those sales 201 7 and 201 6, respectively. There were no gross losses recognized on the sales of securities in 2015 .

Loans are placed on non-accrual status when the loan is greater than 90 days past due , the borrower, in management’s opinion, may be unable to meet payment obligations as they become due or when required by regulatory provisions . 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 status . Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured and generally only after six months of satisfactory performance.

Impaired loans include nonperforming commercial loans but also include loans modified in troubled debt restructurings where concessions have been granted to borrowers experiencing financial difficulties. These concessions could include a reduction in the interest rate on the loan, payment extensions, forgiveness of principal, forbearance or other actions intended to maximize collection. Interest on impaired loans is recorded based on the performance of the loan. All interest received on impaired loans that are on nonaccrual status is accounted for on the cash-basis method until qualifying for return to accrual status . Interest is accrued per the contract for impaired loans that are performing.

Commercial Loan Grades Definition of Loan Grades . Loan grades are numbered 1 through 8. Grades 1-4 are "pass" credits, grade 5 [ Special Mention ] loans are "criticized" assets, and grades 6 [Substandard], 7 [Doubtful] and 8 [Loss] are "classified" assets. The use and application of these grades by the Bank conform to the B ank's policy and regulatory definitions. Pass . Pass credits are loans in grades prime through fair. These are at least considered to be credits with acceptable risks and would be granted in the normal course of lending operations. Special Mention. Special mention credits have potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the credits or in the Bank ’s credit position at some future date. If weaknesses cannot be identified, classifying as special mention is not appropriate. Special mention credits are not adversely classified and do not expose the Bank to sufficient risk to warrant an adverse classification. No apparent loss of principal or interest is expected. Substandard. Substandard credits are inadequately protected by the current sound worth and paying capacity of the obligor or by 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. Credits so classified must have a well-defined weakness, or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Bank will sustain some loss i f the deficiencies are not corrected. Doubtful. A doubtful extension of credit has all the weaknesses inherent in a substandard asset with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. The possibility of loss is extremely high, but because of certain important and reasonably specific pending factors that may work to the advantage and strengthening of the asset, its classification as an estimated loss is deferred until its more exact status may be determined. Pending factors include proposed merger, acquisition, or liquidation procedures, capital injection, perfecting liens on additional collateral, and refinancing plans. Doubtful classification for an entire credit should be avoided when collection of a specific portion appears highly probable with the adequately secured portion graded Substandard.  Retail Loan Grades Pass. Pass credits are loans that are currently performing as agreed and are not troubled debt restructurings. Special Mention . Special mention credits have potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the credits or in the Bank’s credit position at some future date. If weaknesses cannot be identified, classifying as special mention is not appropriate. Special mention credits are not adversely classified and do not expose the Bank to sufficient risk to warrant an adverse classification. No apparent loss of principal or interest is expected. Substandard. Substandard credits are loans that have reason to be considered to have a weakness and placed on non-accrual. This would include all retail loans over 90 days and troubled debt restructurings. During 2017, special mention commercial business loans increased as management determined that a few credits had potential weaknesses deserving management’s close attention. These credits were performing as agreed as of December 31, 2017.

Commercial real estate lending typically involves higher loan principal amounts and the repayment of these loans is generally dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. Commercial real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. The properties securing the Company’s commercial real estate portfolio are diverse in terms of type and geographic location. Management monitors and evaluates commercial real estate loans based on collateral, geography and risk grade criteria. As a general rule, the Company avoids financing single purpose projects unless other underwriting factors are present to help mitigate risk. In addition, management tracks the level of owner-occupied commercial real estate loans versus non-owner occupied loans. Commercial construction loans are underwritten utilizing feasibility studies, independent appraisal reviews, sensitivity analyses of absorption and lease rates and financial analyses of the developers and property owners. Construction loans are generally based on estimates of costs and value associated with the complete project. These estimates may be inaccurate. Construction loans often involve the disbursement of substantial funds with repayment substantially dependent on the success of the ultimate project. Sources of repayment for these types of loans may be pre-committed permanent loans from approved long-term lenders, sales of developed property or an interim loan commitment from the Company until permanent financing is obtained. These loans are closely monitored by on-site inspections and are considered to have higher risks than other real estate loans due to their ultimate repayment being sensitive to interest rate changes, governmental regulation of real property, general economic conditions and the availability of long-term financing. Commercial business loans are primarily based on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not be as expected and the collateral securing these loans may fluctuate in value. Most commercial loans are secured by the assets being financed or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee; however, some loans may be made on an unsecured basis. In the case of loans secured by accounts receivable, the availability of funds for the repayment of these loans may be substantially dependent on the ability of the borrower to collect amounts due from its customers. Residential and Consumer With respect to residential loans that are secured by one-to-four family residences and are primarily owner occupied, the Company generally establishes a maximum loan-to-value ratio and requires private mortgage insurance ( PMI ) if that ratio is exceeded. Consumer open end and junior lien loans are typically secured by a subordinate interest in one-to-four family residences, and other consumer loans are secured by consumer assets such as automobiles or recreational vehicles. Some consumer loans are unsecured such as small installment loans and certain lines of credit. Repayment of these loans is primarily dependent on the personal income of the borrowers, which can be impacted by economic conditions in their market areas such as unemployment levels. Repayment can also be impacted by changes in property values on residential properties. Risk is mitigated by the fact that the loans are of smaller individual amounts and spread over a large number of borrowers.  The following tables detail activity in the allowance for loan losses by portfolio segment for the year s ended December 31, 201 7 , 201 6 and 201 5 . Allocation of a portion of the allowance to one category of loans does not preclude its availability to absorb losses on other segments.

These concessions typically result from our loss mitigation activities and could include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance or other actions. Modifications of terms for our loans and their inclusion as troubled debt restructurings are based on individual facts and circumstances. When we modify loans in a troubled debt restructuring, we evaluate any possible impairment similar to other impaired loans based on the present value of expected future cash flows, discounted at the contractual interest rate of the original loan agreement, or we use the current fair value of the collateral, less selling costs for collateral dependent loans. If we determine that the value of the modified loan is less than the recorded investment in the loan (net of previous charge-offs, deferred loan fees or costs and unamortized premium or discount), impairment is recognized through a specific reserve or a charge-off to the allowance. Loans retain their accrual status at the time of their modification. As a result, if a loan is on nonaccrual at the time it is modified, it stays as nonaccrual until a period of satisfactory performance, generally six months, is obtained. If a loan is on accrual at the time of the modification, the loan is evaluated to determine the collection of principal and interest is reasonably assured and generally stays on accrual. At December 31, 201 7 and 201 6 , the Company had a number of loans that were modified in troubled debt restructurings and impaired. The modification of terms of such loans included one or a combination of the following: an extension of maturity, a reduction of the stated interest rate or a permanent reduction of the recorded investment in the loan. The following tables describe troubled debts restructured during the years ended December 31, 2017, 2016 and 2015.    2017  No. of Loans Pre-Modification Recorded Balance Post-Modification Recorded Balance  Real estate  Consumer closed end first mortgage 7 $ 320 $ 324  Consumer open end and junior liens 2 16 16  Commercial and industrial 1 72 72      2016  No. of Loans Pre-Modification Recorded Balance Post-Modification Recorded Balance  Real estate  Commercial 1 $ 406 $ 406  Construction and development 1 83 83  Consumer closed end first mortgage 14 881 911  Consumer open end and junior liens 1 39 39   Other loans  Consumer loans  Auto 1 4 4  Boat/RVs 3 56 56  Other 2 7 7      2015  No. of Loans Pre-Modification Recorded Balance Post-Modification Recorded Balance  Real estate  Commercial 4 $ 2,399 $ 2,406  Construction and development 1 155 155  Consumer closed end first mortgage 8 287 287  Consumer open end and junior liens 3 51 51   Other loans  Consumer loans  Auto 2 25 25  Commercial and industrial 1 88 83  The impact on the allowance for loan losses was insignificant as a result of these modifications.

Derivative Financial Instruments [Abstract]
Derivative Financial Instruments	Note 10: Derivative Financial Instruments The Company has certain interest rate derivative positions that are not designated as hedging instruments. Derivative assets and liabilities are recorded at fair value on the Consolidated Balance Sheet and do not take into account the effects of master netting agreements. Master netting agreements allow the Company to settle all derivative contracts held with a single counterparty on a net basis, and to offset net derivative positions with related collateral, where applicable. These derivative positions relate to transactions in which the Company enters into an interest rate swap with a client while at the same time entering into an offsetting interest rate swap with another financial institution. In connection with each transaction, the Company agrees to pay interest to the client on a notional amount at a variable interest rate and receive interest from the client on the same notional amount at a fixed interest rate. At the same time, the Company agrees to pay another financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. The transaction allows the client to effectively convert a variable rate loan to a fixed rate. Because the terms of the swaps with the customers and the other financial institution offset each other, with the only difference being counterparty credit risk, changes in the fair value of the underlying derivative contracts are not materially different and do not significantly impact the Company’s Consolidated Statements of Income. The notional amount of customer-facing swaps as of December 31, 2017 and 2016 was approximately $17.3 million and $14.6 million, resp ectively.  The following table shows the amounts of derivative financial instruments at December 31, 2017 and 2016.

Other Borrowings	Note 13: Other Borrowings Other borrowings consisted of the following component as of December 31:     2017 2016  Subordinated debenture, net of discount $ 4,232 $ 4,189  The Company assumed $5.0 million in debentures as the result of the acquisition of MFB Corp. in 2008. In 2005, MFB Corp. had formed MFBC Statutory Trust I (MFBC), as a wholly owned business trust, to sell trust preferred securities. The proceeds from the sale of these trust preferred securities were used by the trust to purchase an equivalent amount of subordinated debentures from the acquired company. The junior subordinated debentures are the sole assets of MFBC and are fully and unconditionally guaranteed by the Company. The junior subordinated debentures and the trust preferred securities pay interest and dividends, respectively, on a quarterly basis. The rate resets quarterly at the prevailing three-month LIBOR rate plus 170 basis points, which was 3.29% at December 31, 2017 . The Company may redeem the trust preferred securities, in whole or in part, without penalty, on or after September 15, 2010. These securities mature on September 15, 2035 . The net balance of the securities as of December 31, 2017 was $4.2 million due to the fair value adjustment of the securities made at the time of the acquisition.

At December 31, 2017, the Company has substantially completed its accounting for the tax effects of enactment of the Tax Act. For deferred tax assets and liabilities, amounts were remeasured based on the rates expected to reverse in the future, which is now 21%. Based on this new law, we recorded an additional tax expense of $2.0 million due to the revaluation of the company’s deferred tax asset. The Company continues to analyze certain aspects of the Tax Act and further refinements are possible, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts . W e do not expect these adjustments to materially impact our financial statements. The components of the net deferred tax asset included on the consolidated balance sheets at December 31, were as follows:     December 31,  2017 2016  Assets  Allowance for loan losses $ 3,278 $ 4,999  Deferred compensation 2,142 3,174  Business tax and AMT credit carryovers 3,434 4,100  Net operating loss carryover 1,161 1,496  Goodwill impairment 903 1,780  Purchase accounting adjustments 624 1,010  Other-than-temporary-impairment, available for sale securities - 37  Unrealized loss on securities available for sale - 776  Other 457 857  Total assets 11,999 18,229   Liabilities  Unrealized gain on securities available for sale $ (153) $ -  Depreciation and amortization (382) (504)  FHLB stock (253) (385)  State income tax (331) (551)  Loan fees (257) (355)  Investments in limited partnerships (1,402) (2,072)  Mortgage servicing rights (402) (564)  Other (882) (972)  Total liabilities (4,062) (5,403)   Valuation Allowance  Beginning balance (789) (1,220)  Decrease during period 382 431  Ending balance (407) (789)  Net deferred tax asset $ 7,530 $ 12,037  The Company has unused business income tax credits of $2.1 million that will begin to expire in 2029 and a state net operating loss carryover of $17.9 million that will begin to expire in 2023 . In addition, the Company has an AMT credit carryover of $ 1.4 million with an unlimited carryover period. Management believes that the Company will be able to utilize the benefits recorded for the state loss carryforwards and federal credits within the allotted time periods, except for the amount represented by the valuation allowance. The valuation allowance has been recorded for the possible inability to use a portion of the state net operating loss carryover. Retained earnings include approximately $14.7 million for which no deferred income tax liability has been recognized. This amount represents an allocation of income to bad debt deductions as of December 31, 1987 for tax purposes only. Reduction of amounts so allocated for purposes other than tax bad debt losses or adjustments arising from carryback of net operating losses would create income for tax purposes only, which income would be subject to the then-current corporate income tax rate. The unrecorded deferred income tax liability on the above amounts was approximately $3.1 million at December 31, 2017 .  The Company’s federal and state income tax returns have been closed without audit by the IRS through the year ended December 31, 2013.

Commitments and Contingent Liabilities [Abstract]
Commitments and Contingent Liabilities	Note 17: Commitments and Contingent Liabilities In the normal course of business , there are outstanding commitments and contingent liabilities, such as commitments to extend credit and standby letters of credit, which are not included in the accompanying financial statements. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instruments for commitments to extend credit and standby letters of credit is represented by the contractual or notional amount of those instruments. The Company uses the same credit policies in making such commitments as it does for instruments that are included in the consolidated statements of financial condition. Financial instruments whose contract amount represents credit risk as of December 3 1:     2017 2016  Loan commitments $ 232,866 $ 224,900  Standby letters of credit 3,021 2,541  Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer's credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management's credit evaluation. Collateral held varies, but may include residential real estate, income-producing commercial properties, or other assets of the borrower. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party . The Company and Bank are also subject to claims and lawsuits that arise primarily in the ordinary course of business. It is the opinion of management that the disposition or ultimate resolution of such claims and lawsuits at December 31, 2017 will not have a material adverse effect on the consolidated financial position of the Company. The Company has entered into employment agreements with certain officers that provide for the continuation of salary and certain benefits for a specified period of time under certain conditions. Under the terms of the agreement, these payments could occur in the event of a change in control of the Company or other circumstances .  Mortgage loans in the process of origination represent amounts that the Company plans to fund within a normal period of 60 to 90 days, and which are primarily intended for sale to investors in the secondary market. Total mortgage loans in the process of origination amounted to $3.6 million and $4.4 million, and mortgage loans held for sale amounted to $4.6 million and $4.1 million, at December 31, 2017 and 2016, respectively.

Regulatory Capital [Abstract]
Regulatory Capital	Note 19: Regulatory Capital The Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank’s assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Furthermore, the Bank’s regulators could require adjustments to regulatory capital not reflected in these financial statements. Quantitative measures established by regulation to ensure capital adequacy require the Company and Bank to maintain minimum amounts and ratios (set forth in the table below) of total , Tier I and Common Equity Tier I capital (as defined in the regulations) to risk-weighted assets (as defined) and of Tier I capital to average assets (as defined). As of December 31, 201 7 and 201 6 , the Company and Bank meet all capital adequacy requirements to which it is subject.  I n July 2013, the three federal bank regulatory agencies jointly published final rules (the Basel III Capital Rules) establishing a new comprehensive capital framework for U.S. banking organizations. The rules implement the Basel Committee’s December 2010 framework known as “Basel III” for strengthening international capital standards as well as certain provisions of the Dodd-Frank Act. These rules substantially revise the risk-based capital requirements applicable to bank holding companies and depository institutions, compared to the current U.S. risk-based capital rules. The Basel III Capital Rules define the components of capital and address other issues affecting the numerator in banking institutions’ regulatory capital ratios. These rules also address risk weights and other issues affecting the denominator in banking institutions’ regulatory capital ratios and replace the existing risk-weighting approach with a more risk-sensitive approach. The Basel III Capital Rules were effective for the Company and Bank on January 1, 2015 (subject to a four-year phase-in period).  The Company’s and Bank’s actual capital amounts and ratios as of December 31, are presented in the table s below.

(4) Total Capital to Risk-Weighted Assets.  The minimum capital requirements exclude the capital conservation buffer required to avoid limitations on capital distributions, including dividend payments and certain discretionary bonus payments to executive officers. The capital conservation buffer is being phased in annually, which started January 1, 2016, at the rate of 0.625% per year until fully phased in during 2019. The capital conservation buffer was 1.25% at December 31, 2017. The unrealized gain or loss on available for sale securities is not included in computing regulatory capital. As of December 31, 2017, the Bank is in excess of the capital conversation buffer requirements.

Employee Benefits [Abstract]
Employee Benefits	 Note 20: Employee Benefits The Company has a retirement savings 401(k) plan in which substantially all employees may participate. The contributions are discretionary and determined annually. The Company matches employees' contributions at the following rates: 100 percent of participant contributions up to 4 % and 50 percent of participant contributions f rom 4 - 6 %, not to exceed a maximum of 5 % of their compensation. The Company’s expense for the plan was $957,000 , $938,000 and $810 ,000 for 201 7 , 201 6 and 201 5 , respectively. The Company has an executive benefit plan and deferred compensation arrangements for the benefit of certain officers. The Company also has deferred compensation arrangements with certain directors whereby, in lieu of previously receiving fees, the directors or their beneficiaries will be paid benefits for an established period following the director’s retirement or death. These arrangements are informally funded by life insurance contracts which have been purchased by the Company. The Company records a liability for these vested benefits based on the present value of future payments. The Company’s expense for the plan was $652 ,000 , $ 676 ,000 and $ 669 ,000 for 201 7 , 201 6 and 201 5 , respectively.

Stock Option Plans [Abstract]
Stock Option Plans	Note 21: Stock Option Plans Under the Company’s stock option plans, which are accounted for in accordance with FASB ASC 718, Stock Compensation , the Company grants selected executives and other key employees and directors incentive and non-qualified stock option awards that vest and become fully exercisable at the discretion of the Compensation Committee as the options are granted. As of the end of the 2017, t he Company wa s authorized to grant options under our stock option plan approved in 2008 . Under certain provisions of the plan, the number of shares available for grant may be increased without shareholder approval by the amount of shares surrendered as payment of the exercise price of the stock option and by the number of shares of common stock of the Company that could be repurchased by the Company using proceeds from the exercise of stock options. The Company had a stock option plan that was approved in 2000 that expired in 2015. Under the plan provisions, all option grants that have not been exercised or expired are still exercisable until the maturity or the participant forfeits the grant. No additional grants of options can be made from this plan. The fair value of each option award is estimated on the date of grant using a Black-Scholes option valuation model that uses the assumptions noted in the following table. Expected volatility is based on historical volatility of the Company’s stock and other factors. The Company uses historical data to estimate timing of option exercise s and employee termination s within the valuation model; separate groups of employees that have similar historical exercise behavior are considered separately for valuation purposes. The expected term of options granted represents the period of time that options are expected to be outstanding; the range given below results from certain groups of employees exhibiting different behavior. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The discount rate for post-vesting restrictions is estimated based on the Company’s credit-adjusted risk-free rate of return.  The following is a summary of the status of the Company’s stock option plan s and changes in th ese plan s during 2017 .     2017  Options Shares Weighted- Average Exercise Price Weighted-Average Remaining Contractual Life Aggregate Intrinsic Value  Outstanding, beginning of year 304,561 $ 9.90  Exercised 65,161 17.73  Outstanding and exercisable, end of year 239,400 $ 7.78 7.6 years $ 7,236  There were 65,161 , 77,600 and 186,059 options exercised during the years ended December 31, 2017, 2016 and 2015. There were no options granted during those periods. The Company will fulfill options with authorized but unissued shares of stock from the 352,741 shares the Company has authorized under the current shareholder-approved stock option and incentive plans. There were 58,003 shares remaining to be granted under the current plan. The Company will also fulfill options with authorized but unissued shares of stock from the 141,462 shares the Company has authorized under the 2000 stock option plan. Outstanding options may continue to be exercised from that plan; however no further grants can be made.  Cash received from options exercised under all share-based payment arrangements for years ended December 31, 2017, 2016 and 2015 was $1.2 million, $976,000 and $2.0 million, respectively. The intrinsic value on options exercised during the years ended December 31, 2017, 2016 and 2015 was $1.1 million, $911,000 and $2.2 million, resp ectively.

Fair Values of Financial Instruments	 Note 23: Fair Values of Financial Instruments Fair value is 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. Fair value measurements must maximize the use of observable inputs and minimize the use of unobservable inputs. There is a hierarchy of three levels of inputs that may be used to measure fair value: Level 1 Quoted prices in active markets for identical assets or liabilities Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities Level 3 Unobservable inputs supported by little or no market activity and are significant to the fair value of the assets or liabilities Items Measured at Fair Value on a Recurring Basis Following is a description of the valuation methodologies and inputs used for instruments measured at fair value on a recurring basis and recognized in the accompanying comparative balance sheet, as well as the general classification of such instruments pursuant to the valuation hierarchy.  Available for Sale Securities Where quoted market prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. The Company uses a third-party provider to provide market prices on its securities. Pooled trust preferred securities prices are evaluated by a third party. Level 1 securities include marketable equity securities. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics or discounted cash flows. Level 2 securities include mortgage-backed, collateralized mortgage obligations, municipal, federal agency and certain corporate obligation securities. In certain cases where Level 1 or Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy and include certain corporate obligation securities. Third party vendors compile prices from various sources and may apply such techniques as matrix pricing to determine the value of identical or similar investment securities (Level 2). Matrix pricing is a mathematical technique widely used in the banking industry to value investment securities without relying exclusively on quoted prices for specific investment securities but rather relying on investment securities relationship to other benchmark quoted investment securities. Any investment security not valued based upon the methods above are considered Level 3. Interest Rate Derivative Agreements Interest rate swap positions, both assets and liabilities, are valued by a third-party pricing agent using an income approach and utilizing models that use as their basis readily observable market parameters. This valuation process considers various factors including interest rate yield curves, time value and volatility factors. The following table presents the fair value measurements of assets and liabilities measured on a recurring basis and the level within the ASC 820 fair value hierarchy.

These non-recurring fair value adjustments typically are a result of the application of lower of cost or fair value accounting or a write-down occurring during the period. The following is a description of the valuation methodologies used for certain assets that are recorded at fair value.  The following table s present quantitative information about unobservable inputs used in recurring and nonrecurring Level 3 fair value measurements.

Interest-Bearing Time Deposits – The fair value of interest-bearing time deposits approximates carrying value. Loans Held For Sale - Fair values are based on quoted market prices. Loans - The fair value for loans is estimated using discounted cash flow analyses using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. FHLB Stock - Fair value of FHLB stock is based on the price at which it may be resold to the FHLB. Interest Receivable/Payable - The fair values of interest receivable/payable approximate carrying values. Derivative Instruments - The fair values of interest rate swaps reflects the estimated amounts that would have been received to terminate these contracts at the reporting date based upon pricing or valuation models applied to current market information. Deposits - The fair values of noninterest-bearing, interest-bearing demand and savings accounts are equal to the amount payable on demand at the balance sheet date. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on such time deposits. FHLB Advances - The fair value of these borrowings is estimated using a discounted cash flow calculation, based on current rates for similar debt for periods comparable to the remaining terms to maturity of these advances. Other Borrowings - The fair value of these borrowings is estimated using discounted cash flow analyses using interest rates for similar financial instruments. Off-Balance Sheet Commitments - Commitments include commitments to purchase and originate mortgage loans, commitments to sell mortgage loans and standby letters of credit and are generally of a short-term nature. The fair values of such commitments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing. The fair value of these instruments is insignificant.

Nature of Operations and Summ35

Nature of Operations and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2017
Nature of Operations and Summary of Significant Accounting Policies [Abstract]
Consolidation	Consolidation - The consolidated financial statements include the accounts of the Company, the Bank, and the Bank’s subsidiaries, after elimination of all material intercompany transactions.
Cash Equivalents	Cash Equivalents - The Company considers all liquid investments with original maturities of three months or less to be cash equivalents. At December 31, 201 7 and 201 6 , cash equivalents consisted primarily of money market accounts with brokers and checking accounts with government sponsored entities. At December 31, 2017, the Company’s cash accounts exceeded federally insured limits by approximately $ 6.1 million. Included in this amount are uninsured accounts of approximately $ 2.6 million at the Federal Reserve Bank of Chicago and Federal Home Loan Bank of Indianapolis.
Interest-bearing time deposits	Interest-bearing time deposits – The fair value of interest-bearing time deposits approximates carrying value.
Derivative Instruments	Derivative Instruments – The Company occasionally enters into derivative financial instruments as part of its interest rate risk strategies. These derivative financial instruments consist primarily of interest rate swaps. These instruments are carried at the fair value of the derivatives and reflects the estimated amounts that would have been received to terminate these contracts at the reporting date based upon pricing or valuation models applied to current market information.  The Company offers interest rate derivative products (e.g. interest rate swaps) to certain of its high-quality commercial borrowers. This product allows customers to enter into an agreement with the Company to swap their variable rate loan to a fixed rate. These derivative products are designed to reduce, eliminate or modify the risk of changes in the borrower’s interest rate. The extension of credit incurred through the execution of these derivative products is subject to the same approvals and rigorous underwriting standards as the related traditional credit product. The Company limits its risk exposure to these products by entering into a mirror-image, offsetting swap agreement with a separate, well-capitalized and rated counterparty. These transactions are ratified by the Asset Liability Committee. By using these interest rate swap arrangements, the Company is also better insulated from the interest rate risk associated with underwriting fixed-rate loans. These derivative products do not qualify for hedge accounting. The derivatives are recorded on the balance sheet at fair value and changes in fair value of both the customer and the offsetting swap agreements are recorded (and essentially offset) in non-interest income.
Investment Securities	Investment Securities - Certain debt securities that management has the positive intent and ability to hold to maturity are classified as “held to maturity” and recorded at amortized cost . At December 31, 2017 and 2016, no securities were classified as held to maturity . Securities not classified as held to maturity, including equity securities with readily determinable fair values, are classified as “available for sale” and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income , net of tax . Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. When the Company does not intend to sell a debt security, and it is more likely than not the Company will not have to sell the security before recovery of its cost basis, it recognizes the credit component of an other-than-temporary impairment of a debt security in earnings and the remaining portion in other comprehensive income. For held to maturity debt securities, the amount of an other-than-temporary impairment recorded in other comprehensive income for the noncredit portion of a previous other-than-temporary impairment is amortized prospectively over the remaining life of the security on the basis of the timing of future estimated cash flows of the security. T he Company’s consolidated statement of income reflects the full impairment (that is, the difference s between the security’s amortized cost basis and fair value) on debt securities that the Company intends to sell or would more likely than not be required to sell before the expected recovery of the amortized cost basis. For available for sale and held to maturity debt securities that management has no intent to sell and believes that it more likely than not will not be required to sell prior to recovery, only the credit loss component of the impairment is recognized in earnings, while the noncredit loss is recognized in accumulated other comprehensive income. The credit loss component recognized in earnings is identified as the amount of principal cash flows not expected to be received over the remaining term of the security as projected based on cash flow projections. For equity securities, when the Company has decided to sell an impaired available for sale security and does not expect the fair value of the security to fully recover before the expected time of sale, the security is deemed other-than-temporarily impaired in the period in which the decision to sell is made. The Company recognizes an impairment loss when the impairment is deemed other than temporary even if a decision to sell has not been made. Declines in the fair value of securities below their cost that are other-than-temporary are reflected as realized losses. In estimating other-than-temporary losses, management considers the length of time and extent that fair value has been less than cost, the financial condition and near-term prospects of the issuer, and the Company’s ability and intent to hold the security for a period sufficient to allow for any anticipated recovery in fair value.
Loans held for sale	Loans held for sale are carried at the lower of aggregate cost or market. Market is determined using the aggregate method. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income based on the difference between estimated sales proceeds and aggregate cost.
Loans	Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoffs are reported at their outstanding principal balances adjusted for unearned income, charge-offs, the allowance for loan losses, any unamortized deferred fees or costs on originated loans and unamortized premiums or discounts on purchased loans. For loans amortized at cost, interest income is accrued based on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, as well as premiums and discounts, are deferred and amortized as a level yield adjustment over the respective term of the loan. The accrual of interest on mortgage , consumer and commercial loans is discontinued at the time the loan is 90 days past due unless the credit is well-secured and in process of collection. Past due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date if collection of 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. Discounts and premiums on purchased residential real estate and commercial loans is amortized to income using the interest method over the remaining period to contractual maturity, adjusted for anticipated prepayments. Discounts and premiums on purchased consumer loans are recognized over the expected lives of the loans using methods that approximate the interest method.
Allowance for loan losses	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 income. Loan losses are charged against the allowance when management believes the inability to collect a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. We maintain an allowance for loan losses to absorb losses inherent in the loan portfolio. The allowance is based on ongoing, quarterly assessments of the estimated losses inherent in the loan portfolio. Our methodology for assessing the appropriateness of the allowance consists of several key elements, including the general allowance and specific allowances for identified problem loans and portfolio segments. In addition, the allowance incorporates the results of measuring impaired loans as provided in ASC 310, Receivables . These accounting standards prescribe the measurement methods, income recognition and disclosures related to impaired loans. The general allowance is calculated by applying loss factors to outstanding loans based on the internal risk evaluation of such loans or pools of loans. Changes in risk evaluations of both performing and nonperforming loans affect the amount of the general allowance. Loss factors are based on our historical loss experience as well as on significant factors that, in management’s judgment, affect the collectability of the portfolio as of the evaluation date. The historical loss experience is determined by portfolio segment and is based on the actual loss history experienced by the Company over the prior three years. Management believes the three year historical loss experience methodology is appropriate in the current economic environment, as it captures loss rates that are comparable to the current period being analyzed. The appropriateness of the allowance is reviewed by management based upon its evaluation of then-existing economic and business conditions affecting our key lending areas and other conditions, such as credit quality trends (including trends in non-performing loans expected to result from existing conditions), collateral values, loan volumes and concentrations, specific industry conditions within portfolio segments and recent loss experience in particular segments of the portfolio that existed as of the balance sheet date and the impact that such conditions were believed to have had on the collectability of the loan. Senior management reviews these conditions quarterly in discussions with our senior credit officers. To the extent that any of these conditions is evidenced by a specifically identifiable problem credit or portfolio segment as of the evaluation date, management’s estimate of the effect of such condition may be reflected as a specific allowance applicable to such credit or portfolio segment. Where any of these conditions is not evidenced by a specifically identifiable problem credit or portfolio segment as of the evaluation date, management’s evaluation of the loss related to this condition is reflected in the general allowance for loan losses. The evaluation of the inherent loss with respect to these conditions is subject to a higher degree of uncertainty because they are not identified with specific problem credits or portfolio segments. The allowance for loan losses is based on estimates of losses inherent in the loan portfolio. Actual losses can vary significantly from the estimated amounts. Our methodology as described permits adjustments to any loss factor used in the computation of the general allowance in the event that, in management’s judgment, significant factors which affect the collectability of the portfolio as of the evaluation date are not reflected in the loss factors. By assessing the probable incurred losses inherent in the loan portfolio on a quarterly basis, we are able to adjust specific and inherent loss estimates based upon any more recent information that has become available. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the ability to collect 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 allocated and general components. The allocated component relates to loans that are classified as impaired. For those loans that are 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 charge-off experience and expected loss given default derived from the Company’s internal risk rating process. Other adjustments may be made to the allowance for pools of loans after an assessment of internal or external influences on credit quality that are not fully reflected in the historical loss or risk rating data. A loan is considered impaired when, based on current information and events, it is probable that the Company 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. Groups of loans with similar risk characteristics are collectively evaluated for impairment based on the group’s historical loss experience adjusted for changes in trends, conditions and other relevant factors that affect repayment of the loans. Accordingly, the Company does not separately identify individual consumer and residential loans for impairment measurements, unless such loans are the subject of a restructuring agreement due to financial difficulties of the borrower.
Premises and equipment	Premises and equipment are carried at cost net of accumulated depreciation. Depreciation is computed using the straight-line method based principally on the estimated useful lives of the assets which range from 3 to 40 years. Maintenance and repairs are expensed as incurred while major additions and improvements are capitalized. Gains and losses on dispositions are included in current operations.
Federal Home Loan Bank stock	Federal Home Loan Bank stock is a required investment for institutions that are members of the Federal Home Loan Bank (FHLB) system. The required investment in the common stock is based on a predetermined formula, carried at cost and is evaluated for impairment.
Mortgage-servicing	Mortgage-servicing assets are recognized separately when rights are acquired through purchase or through sale of financial assets. Under the servicing assets and liabilities accounting guidance , servicing rights resulting from the sale or securitization of loans originated by the Company are initially measured at fair value at the date of transfer. The Company subsequently measures each class of servicing asset using the amortization method. Under the amortization method, servicing rights are amortized in proportion to and over the period of estimated net servicing income. The amortized assets are assessed for impairment based on fair value at each reporting date. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. These variables change from quarter to quarter as market conditions and projected interest rates change, and may have an adverse impact on the value of the mortgage servicing right and may result in a reduction to noninterest income. Each class of separately recognized servicing assets subsequently measured using the amortization method are evaluated and measured for impairment. Impairment is determined by stratifying rights into tranches based on predominant characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual tranche, to the extent that fair value is less than the carrying amount of the servicing assets for that tranche. The valuation allowance is adjusted to reflect changes in the measurement of impairment after the initial measurement of impairment. Changes in valuation allowances are reported with net servicing fees on the income statement. Fair value in excess of the carrying amount of servicing assets for that stratum is not recognized. Servicing fee income is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. The amortization of mortgage servicing rights is netted against loan servicing fee income.
Intangible assets	Intangible assets are being amortized on an accelerated basis over periods ranging from three to 11 years. Such assets are periodically evaluated as to the recoverability of their carrying value.
Income taxes	Income tax es are account ed for in accordance with income tax accounting guidance. The income tax accounting guidance results in two components of income tax expense: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Company determines deferred income taxes using the balance shee t method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred tax assets are evaluated on a quarterly basis for recoverability based on all available evidence. This process involves significant management judgment about assumptions that are subject to change from period to period based on changes in tax laws or variances between our future projected operating performance and our actual results. We are required to establish a valuation allowance for deferred tax assets if we determine, based on available evidence at the time the determination is made, that it is more likely than not that some portion or all of the deferred tax assets will not be realized. In determining the more-likely-than-not criterion, we evaluate all positive and negative available evidence as of the end of each reporting period. Future adjustments to the deferred tax asset valuation allowance, if any, will be determined based upon changes in the expected realization of the net deferred tax assets. The realization of the deferred tax assets ultimately depends on the existence of sufficient taxable income in either the carry back or carry forward periods under applicable tax laws. Due to significant estimates utilized in establishing the valuation allowance and the potential for changes in facts and circumstances, it is reasonably possible that we will be required to record adjustments to the valuation allowance in the near term if estimates of future taxable income during the carry forward period are reduced. Such a charge could have a material adverse effect on our results of operations, financial condition, and capital position. Uncertain tax positions are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more likely than not means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances and information available at the reporting date and is subject to management’s judgment. The Company recognizes interest and penalties on income taxes as a component of income tax expense. The Company files consolidated income tax returns with its subsidiaries.
Earnings per share	Earnings per share is computed based upon the weighted-average common and common equivalent shares outstanding during each year.
Comprehensive income	Comprehensive income consists of net income and other comprehensive income, net of applicable income taxes. Other comprehensive income includes unrealized gains (losses) on available for sale securities, unrealized gains (losses) on available for sale securities for which a portion of an other-than-temporary impairment has been recognized in income, unrealized and realized gains and losses in derivative financial instruments and changes in the funded status of defined benefit pension plans.
Stock options	Stock options - The Company has stock-based employee compensation plans, which are described more fully in Note 20.
