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 subsidiaries, 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, central and southern 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, 2018 and 2017, cash equivalents consisted primarily of money market accounts with brokers and checking accounts with government sponsored entities. At December 31, 2018, the Company’s cash accounts exceeded federally insured limits by approximately $6.1 million. Included in this amount are uninsured accounts of approximately $1.6 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, 2018 and 2017, 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. The Company’s consolidated statement of income reflects the full impairment (that is, the differences 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. Acquisition accounting and acquired loans – We account for our acquisitions under FASB ASC Topic 805, Business Combinations, which requires the use of the acquisition method of accounting. All identifiable assets acquired, including loans, are recorded at fair value. No allowance for loan losses related to the acquired loans is recorded on the acquisition date as the fair value methodology prescribed in FASB ASC Topic 820, Fair Value Measurements. The fair value estimates associated with the loans include estimates related to expected prepayments and the amount and timing of undiscounted expected principal, interest and other cash flows. 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 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 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 15 years. Such assets are periodically evaluated as to the recoverability of their carrying value. Goodwill is maintained by applying the provisions of ASC 350, Intangibles – Goodwill and Other. For purchase acquisitions, the Corporation is required to record the assets acquired, including identified intangible assets, and the liabilities assumed at their fair value, which in many instances involves estimates based on third party valuations, such as appraisals, or internal valuations based on discounted cash flow analysis or other valuation techniques that may include estimates of attrition, inflation, asset growth rates or other relevant factors. In addition, the determination of the useful lives for which an intangible asset will be amortized is subjective. Under ASC 350, the Corporation is required to evaluate goodwill for impairment on an annual basis, as well as on an interim basis, if events or changes indicate that the asset may be impaired, indicating that the carrying value may not be recoverable. The Corporation has elected to test for goodwill impairment as of November 30 of each year and has determined that no impairment exists. Income taxes are accounted 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 sheet 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. Revenue Recognition The Company recognizes revenues as they are earned based on contractual terms, as transactions occur, or as services are provided and collectability is reasonably assured. The Company’s principal source of revenue is interest income from loans and leases and investment securities. The Company also earns noninterest income from various banking and financial services offered primarily through the Bank and its subsidiaries. Interest Income – The largest source of revenue for the Company is interest income which is primarily recognized on an accrual basis according to nondiscretionary formulas in written contracts, such as loan and lease agreements or investment securities contracts. Noninterest Income – The Company earns noninterest income through a variety of financial and transaction services provided to business and consumer clients such as trust and wealth advisory, deposit account, debit card, and mortgage banking. Revenue is recorded for noninterest income based on the contractual terms for the service or transaction performed. In certain circumstances, noninterest income is reported net of associated expenses. 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. Stock options - The Company has stock-based employee compensation plans, which are described more fully in Note 23 of these Notes to Consolidated Financial Statements.

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 subsidiaries, 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, central and southern 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, 2018 and 2017, cash equivalents consisted primarily of money market accounts with brokers and checking accounts with government sponsored entities.

At December 31, 2018, the Company’s cash accounts exceeded federally insured limits by approximately $6.1 million. Included in this amount are uninsured accounts of approximately $1.6 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, 2018 and 2017, 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.

The Company’s consolidated statement of income reflects the full impairment (that is, the differences 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.

Acquisition accounting and acquired loans – We account for our acquisitions under FASB ASC Topic 805, Business Combinations, which requires the use of the acquisition method of accounting. All identifiable assets acquired, including loans, are recorded at fair value. No allowance for loan losses related to the acquired loans is recorded on the acquisition date as the fair value methodology prescribed in FASB ASC Topic 820, Fair Value Measurements. The fair value estimates associated with the loans include estimates related to expected prepayments and the amount and timing of undiscounted expected principal, interest and other cash flows.

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 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 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 15 years. Such assets are periodically evaluated as to the recoverability of their carrying value.

Goodwill is maintained by applying the provisions of ASC 350, Intangibles – Goodwill and Other. For purchase acquisitions, the Corporation is required to record the assets acquired, including identified intangible assets, and the liabilities assumed at their fair value, which in many instances involves estimates based on third party valuations, such as appraisals, or internal valuations based on discounted cash flow analysis or other valuation techniques that may include estimates of attrition, inflation, asset growth rates or other relevant factors. In addition, the determination of the useful lives for which an intangible asset will be amortized is subjective.

Under ASC 350, the Corporation is required to evaluate goodwill for impairment on an annual basis, as well as on an interim basis, if events or changes indicate that the asset may be impaired, indicating that the carrying value may not be recoverable. The Corporation has elected to test for goodwill impairment as of November 30 of each year and has determined that no impairment exists.

Income taxes are accounted 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 sheet 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.

Revenue Recognition The Company recognizes revenues as they are earned based on contractual terms, as transactions occur, or as services are provided and collectability is reasonably assured. The Company’s principal source of revenue is interest income from loans and leases and investment securities. The Company also earns noninterest income from various banking and financial services offered primarily through the Bank and its subsidiaries.

Interest Income – The largest source of revenue for the Company is interest income which is primarily recognized on an accrual basis according to nondiscretionary formulas in written contracts, such as loan and lease agreements or investment securities contracts.

Noninterest Income – The Company earns noninterest income through a variety of financial and transaction services provided to business and consumer clients such as trust and wealth advisory, deposit account, debit card, and mortgage banking. Revenue is recorded for noninterest income based on the contractual terms for the service or transaction performed. In certain circumstances, noninterest income is reported net of associated expenses.

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.

Stock options - The Company has stock-based employee compensation plans, which are described more fully in Note 23 of these Notes to Consolidated Financial Statements.
