Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	2. Statement of Accounting Policies Use of Estimates The preparation of consolidated 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 amounts reported in the consolidated financial statements and accompanying notes. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ. Earnings Per Common Share Basic earnings per common share is computed by dividing net income applicable to common shares (net income less dividend requirements for preferred stock, accretion of preferred stock discount and redemption of preferred stock) by the weighted average number of shares of common stock outstanding during the period. All outstanding unvested share-based payment awards that contain rights to nonforfeitable dividends are considered participating securities for the calculation. Diluted earnings per common share includes the dilutive effect of additional potential common shares issuable under stock options, warrants, restricted stock awards and stock grants. See also Note 4. Comprehensive Income Comprehensive income consists of net income and other comprehensive income (loss). Other comprehensive income (loss) includes unrealized gains and losses on available-for-sale securities and the net unrecognized actuarial losses and unrecognized prior service costs associated with the Company’s Defined Benefit Postretirement Medical Plan. All items included in other comprehensive income are reported net of tax. See also Notes 5, 16 and 25 and the Consolidated Statements of Comprehensive Income. Cash Flows Cash and cash equivalents include amounts due from banks and overnight investments with the Federal Home Loan Bank (“FHLB”) and the Federal Reserve. Cash and amounts due from depository institutions include required balances on hand or on deposit at the FHLB and Federal Reserve of approximately $1,809,000 and $1,896,000, respectively, at December 31, 2016 to meet regulatory reserve and clearing requirements. Net cash flows are reported for customer loan and deposit transactions, interest bearing deposits in other financial institutions and repurchase agreements. Investment Securities M anagement determines the appropriate classification of debt securities at the time of purchase and evaluates such designation as of each balance sheet date. Debt securities are classified as held-to-maturity when First Defiance has the positive intent and ability to hold the securities to maturity and are reported at cost, adjusted for premiums and discounts that are recognized in interest income using the interest method over the period to maturity. Debt securities not classified as held-to-maturity and equity securities are classified as available-for-sale. Available-for-sale securities are stated at fair value, with the unrealized gains and losses, net of tax, reported in other comprehensive income (loss) until realized. Realized gains and losses are included in gains (losses) on securities or other-than-temporary impairment losses on securities. Realized gains and losses on securities sold are recognized on the trade date based on the specific identification method. Interest income includes amortization of purchase premiums and discounts. Premiums and discounts are amortized on the level-yield method without anticipating prepayments, except for mortgage-backed securities where prepayments are expected. Securities with unrealized losses are reviewed quarterly to determine if value impairment is other–than-temporary. In performing this review management considers the length of time and extent that fair value has been less than cost, the financial condition of the issuer, the impact of changes in market interest rates on market value and whether the Company intends to sell or it would be more than likely required to sell the securities prior to their anticipated recovery. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: (1) other-than-temporary impairment (“OTTI”) related to credit loss, which must be recognized in the income statement and (2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of impairment is recognized through earnings. FHLB Stock First Federal is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income. At December 31, 2016, the Company held $13.8 million at the FHLB of Cincinnati and $5,000 at the FHLB of Indianapolis. Loans Receivable Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal amount outstanding, net of deferred loan fees and costs, purchase premiums and discounts and the allowance for loan losses. Deferred fees net of deferred incremental loan origination costs, are amortized to interest income generally over the contractual life of the loan using the interest method without anticipating prepayments. The recorded investment in loans includes accrued interest receivable and net deferred fees and costs and undisbursed loan amounts. Mortgage loans originated and intended for sale in the secondary market are classified as loans held for sale and are carried at the lower of aggregate cost or fair value, as determined by outstanding commitments from investors. Net unrealized losses, if any, are recorded as a valuation allowance and charged to earnings. Mortgage loans held for sale are generally sold with servicing rights retained. The carrying value of mortgage loans sold is reduced by the amount allocated to the servicing right. Gains or losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold. The Company may incur losses pertaining to loans sold to Fannie Mae and Freddie Mac but repurchased due to underwriting issues. Repurchase losses are recognized when the Company determines they are probable and estimable. Interest receivable is accrued on loans and credited to income as earned. The accrual of interest on loans 90 days delinquent or impaired is discontinued when, in management’s opinion, the borrower may be unable to meet payments as they become due. For these loans, interest accrual is only to the extent cash payments are received. The accrual of interest on these loans is generally resumed after a pattern of repayment has been established and the collection of principal and interest is reasonably assured. Acquired Loans The Company acquires loans individually and in groups or portfolios. At acquisition, the Company reviews each loan to determine whether there is evidence of deterioration of credit quality since origination and if it is probable that it will be unable to collect all amounts due according to the loan’s contractual terms. If both conditions exist, the Company determines whether each such loan is to be accounted for individually or whether such loans will be assembled into pools of loans based on common risk characteristics (credit score, loan type and date of origination). The Company considers expected prepayments, and estimates the amount and timing of undiscounted expected principal, interest, and other cash flows (expected at acquisition) for each loan and subsequently aggregated pool of loans. The Company determines the excess of the loan’s or pool’s scheduled contractual principal and contractual interest payments over all cash flows expected at acquisition as an amount that should not be accreted (nonaccretable difference). The remaining amount—representing the excess of the loan’s cash flows expected to be collected over the amount paid—is accreted into interest income over the remaining life of the loan or pool (accretable yield). Over the life of the loan or pool, the Company continues to estimate cash flows expected to be collected, and evaluates whether the present value of its loans determined using the effective interest rates has decreased and, if so, recognizes a loss. Valuation allowances for all acquired loans subject to FASB ASC Topic 310 reflect only those losses incurred after acquisition—that is, the present value of cash flows expected at acquisition that are not expected to be collected. The present value of any subsequent increase in the loan’s or pool’s actual cash flows or cash flows expected to be collected is used first to reverse any existing valuation allowance for that loan or pool. For any remaining increases in cash flows expected to be collected, the Company adjusts the amount of accretable yield recognized on a prospective basis over the loan’s or pool’s remaining life. Allowance for Loan Losses The allowance for loan losses is maintained at a level believed adequate by management to absorb probable incurred losses in the loan portfolio and is based on the size and current risk characteristics of the loan portfolio, an assessment of individual problem loans, actual loss experience, current economic events in specific industries and geographical areas and other pertinent factors, including general economic conditions. Determination of the allowance is inherently subjective as it requires significant estimates, including the amounts and timing of expected future cash flows on impaired loans, estimated losses on pools of homogeneous loans based on historical loss experience and consideration of economic trends, all of which may be susceptible to significant change. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management’s judgment, should be charged off. Beginning June 30, 2015, the Company refined the methodology to its allowance for loan loss calculation pertaining to the general reserve component for non-impaired loans. There was no change to the calculation of the component for reserves on impaired loans. Within the general reserve, the determination of the historical loss component was modified from using a three-year average annual loss rate to a loss migration measurement. The loss migration measurement implemented June 30, 2015, utilized an average of four (4) four-year loss migration periods for each loan portfolio segment with differentiation between loan risk grades. Prior to June 30, 2015, the approach to this component quantified the historical loss by calculating a rolling twelve quarter average annual loss rate for each portfolio segment, without differentiation between loan risk grades. Beginning December 31, 2016 the historical loss calculation was changed from using an average of four (4) four-year loss migration periods to using an average of all four-year loss migration periods to the present beginning with data from the second quarter 2011. Management believes this enhancement is consistent with the rationale of the previous measurement but provides a more precise calculation of historical losses by incorporating more data points for the average loss ratio and including periods that provide a more complete coverage of the full business cycle. Management believes that capturing the risk grade changes and cumulative losses over the life cycle of a loan more accurately depicts management’s estimate of historical losses as well as being more reflective of the ongoing risks in the loan portfolio. These modifications resulted in a change in the general reserves between the loan portfolio segments but did not have a material impact on the overall allowance for loan losses. Loan losses are charged off against the allowance when in management’s estimation it is unlikely that the loan will be collected, while recoveries of amounts previously charged off are credited to the allowance. A provision for loan loss is charged to operations based on management’s periodic evaluation of the factors previously mentioned, as well as other pertinent factors in order to maintain the allowance for loan losses at the level deemed adequate by management. The determination of whether a loan is considered past due or delinquent is based on the contractual payment terms. Loans are considered past due when the contractual amounts due with respect to principal and interest are not received within 30 days of the contractual due date. All loans are placed on nonaccrual status at 90 days past due unless the loan is adequately secured and is in process of collection. Any loan in the portfolio may be placed on nonaccrual status prior to becoming 90 days past due when collection of principal or interest is in doubt. The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. Impaired loans have been recognized in conformity with FASB ASC Topic 310. A loan is impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loans agreement. Loans, for which terms have been modified and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings and classified as impaired. An analysis of the net present value of estimated cash flows is performed and an allowance may be established based on the outcome of that analysis, or if the loan is deemed to be collateral dependent an allowance is established based on the fair value of collateral. All modifications are reviewed by the First Federal’s Chief Credit Officer to determine whether or not the modification constitutes a troubled debt restructure. Commercial and commercial real estate loans are individually evaluated for impairment. If a loan is impaired, a portion of the allowance is allocated so that the loan is reported net of the allowance allocation which is determined based on the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the collateral. Large groups of smaller balance homogeneous loans, such as consumer and residential real estate loans, are collectively evaluated for impairment, and accordingly, they are not separately identified for impairment disclosures. The following portfolio segments have been identified: Commercial Real Estate Loans (consisting of multi-family residential and non-residential): Commercial real estate loans are subject to underwriting standards and processes similar to commercial and industrial loans. These loans are viewed primarily as cash flow loans and the repayment of these loans is largely dependent on the successful operation of the property. Loan performance may be adversely affected by factors impacting the general economy or conditions specific to the real estate market such as geographic location and/or property type. Commercial Loans : Commercial credit is extended primarily to middle market customers. Such credits are typically comprised of working capital loans, loans for physical asset expansion, asset acquisition loans and other business loans. Loans to closely held businesses will generally be guaranteed in full or for a meaningful amount by the businesses' principal owners. Commercial loans are made based primarily on the historical and projected cash flow of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not behave as forecasted and collateral securing loans may fluctuate in value due to economic or individual performance factors. Minimum standards and underwriting guidelines have been established for all commercial loan types. Consumer Finance Loans : Consumer finance loans are generally made to borrowers for a specific consumer purchase and are made based on their ability to repay with their current debt to income as well as the underlying collateral value of the item being purchased. Credit scores are part of the decision process of whether or not credit is extended. Minimum standards and underwriting guidelines have been established for all consumer loan types. 1-4 Family Residential Real Estate Loans : 1-4 family residential real estate loans can be categorized two different ways. One part of this portfolio is owner occupied and are made based primarily on the ability of the individual borrower to support the payments as well as the payments of any other debt the borrower may have outstanding at the time the loan is made. The other part of this portfolio is non-owner occupied income producing property and is made primarily based on the cash flow stream from rental income as well as the cash flow support from the borrower’s unrelated cash flow. Both types of loans have a secondary repayment source of the underlying collateral and generally the loans are not extended at higher than an 80% LTV. Minimum standards and underwriting guidelines have been established for all 1-4 family residential real estate loan types. Construction Loans : The Company defines construction loans as loans where the loan proceeds are controlled by the Company and used exclusively for the improvement of real estate in which the Company holds a mortgage. Home Equity and Improvement Loans : Home Equity and Improvement loans are made to borrowers based on their ability to repay with their current debt to income as well as the underlying collateral value of the real estate taken as security. Minimum standards and underwriting guidelines have been established for all 1-4 family residential real estate loan types. Consumer finance, 1-4 family residential real estate (including construction) and home equity and improvement loans are subject to adverse employment conditions in the local economy which could increase default rate on loans. Servicing Rights Servicing rights are recognized separately when they are acquired through sales of loans. Servicing rights are initially recorded at fair value with the income statement effect recorded in gains on sales of loans. 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. The Company compares the valuation model inputs and results to published industry data in order to validate the model results and assumptions. All classes of servicing assets are subsequently measured using the amortization method which requires servicing rights to be amortized into non-interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans, driven, generally, by changes in market interest rates. Servicing assets are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. Impairment is determined by stratifying rights into groupings based on predominant risk characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. If the Company later determines that all or a portion of the impairment no longer exists for a particular grouping, a reduction of the allowance may be recorded as an increase to income. Changes in valuation allowances are reported with mortgage banking income on the income statement. The fair values of servicing rights are subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and default rates and losses. Servicing fee income, which is reported on the income statement with mortgage banking 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. Servicing fees totaled $3.6 million, $3.5 million and $3.6 million for the years ended December 31, 2016, 2015 and 2014. Late fees and ancillary fees related to loan servicing are not material. See Note 8. Bank Owned Life Insurance The Company has purchased life insurance policies for certain key employees. Bank owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. Premises and Equipment and Long Lived Assets Land is carried at cost. Premises and equipment are carried at cost less accumulated depreciation and amortization computed principally by the straight-line method over the following estimated useful lives: Buildings and improvements 20 to 50 years Furniture, fixtures and equipment 3 to 15 years Long-lived assets to be held and those to be disposed of and certain intangibles are periodically evaluated for impairment. See Note 9. Goodwill and Other Intangibles Goodwill resulting from business combinations prior to January 1, 2009 represents the excess of the purchase price over the fair value of the net assets of businesses acquired. Goodwill resulting from business combinations after January 1, 2009, is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually. The Company has selected November 30 as the date to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Goodwill is the only intangible asset with an indefinite life on First Defiance’s balance sheet. Other intangible assets consist of core deposit and acquired customer relationship intangible assets arising from whole bank, insurance and branch acquisitions. They are initially recorded at fair value and then amortized on an accelerated basis over their estimated lives, which range from five years for non-compete agreements to 10 to 20 years for core deposit and customer relationship intangibles. See Note 10. Real Estate and Other Assets Held for Sale Real estate and other assets held for sale are comprised of properties or other assets acquired through foreclosure proceedings or acceptance of a deed in lieu of foreclosure. These assets are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. Losses arising from the acquisition of such property are charged against the allowance for loan losses at the time of acquisition. These properties are carried at the lower of cost or fair value, less estimated costs to dispose. If fair value declines subsequent to foreclosure, the property is written down against expense. Costs after acquisition are expensed. Stock Compensation Plans Compensation cost is recognized for stock options and restricted share awards issued to employees and directors, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options. Restricted shares awards are valued at the market value of Company stock at the date of the grant. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award. See Note 20. Fair Value of Financial Instruments Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in Note 22. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect the estimates. Transfers of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Mortgage Banking Derivatives Commitments to fund mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of these mortgage loans are accounted for as free standing derivatives. Fair values of these mortgage derivatives are estimated based on changes in mortgage interest rates from the date the interest on the loan is locked. The Company enters into forward commitments for the future delivery of mortgage loans when interest rate locks are entered into, in order to hedge the change in interest rates resulting from its commitments to fund the loans. Changes in fair values of these derivatives are included in mortgage banking income. Operating Segments Management considers the following factors in determining the need to disclose separate operating segments: (1) The nature of products and services, which are all financial in nature. (2) The type and class of customer for the products and services; in First Defiance’s case retail customers for retail bank and insurance products and commercial customers for commercial loan, deposit, life, health and property and casualty insurance needs. (3) The methods used to distribute products or provide services; such services are delivered through banking and insurance offices and through bank and insurance customer contact representatives. Retail and commercial customers are frequently targets for both banking and insurance products. (4) The nature of the regulatory environment; both banking and insurance entities are subject to various regulatory bodies and a number of specific regulations. Quantitative thresholds as stated in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 280, Segment Reporting Dividend Restriction Banking regulations require maintaining certain capital levels and may limit the dividends paid by the savings bank to the holding company. See Note 17 for further details on restrictions. Loan Commitments and Related Financial Instruments Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded. Loss Contingencies Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there are any such matters that will have a material effect on the financial statements. Income Taxes Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. Realization of deferred tax assets is dependent upon the generation of a sufficient level of future taxable income and recoverable taxes paid in prior years. Although realization is not assured, management believes it is more likely than not that all of the deferred tax assets will be realized. An effective tax rate of 35% is used to determine after-tax components of other comprehensive income (loss) included in the statements of stockholders’ equity. See Note 18. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The Company recognizes interest and/or penalties related to income tax matters in income tax expense. Retirement Plans Pension expense is the net of service and interest cost, return on plan assets and amortization of gains and losses not immediately recognized. Employee 401(k) plan expense is the amount of matching contributions. Deferred compensation and supplemental retirement plan expense allocates the benefits over years of service. See Note 16 and 19. Reclassifications Some items in the prior year financial statements were reclassified to conform to the current presentation. Accounting Standards Updates In August 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2016-05 — Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force). The amendments in this update provide guidance on eight specific cash flow issues. The new guidance is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The amendments in this update are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company does not believe this standard will have a material impact on its consolidated statements of cash flows. In June 2016, the FASB issued new accounting guidance in ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments (Topic 326). The main objective of the update is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this objective, the amendments in this update replace the incurred loss impairment methodology in current Generally Accepted Accounting Principles with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to form credit loss estimates. The amendments in this update become effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2019. The Company is currently evaluating the impact of this new accounting standard on the Company's consolidated financial statements. Management’s initial review indicates it has maintained sufficient historical loan data to support the requirement of this pronouncement and is currently evaluating the various loss methodologies to determine their correlations to the Company’s loan segments historical performance. In February 2016, the FASB issued ASU No. 2016-02 — Leases (Topic 842). The objective of the update is to increase transparency

Earnings Per Share [Abstract]
Earnings Per Share [Text Block]	4. Earnings Per Common Share Basic earnings per share is calculated using the two-class method. The two-class method is an earnings allocation formula under which earnings per share is calculated from common stock and participating securities according to dividends declared and participation rights in undistributed earnings. Under this method, all earnings distributed and undistributed, are allocated to participating securities and common shares based on their respective rights to receive dividends. Unvested share-based payment awards that contain non-forfeitable rights to dividends are considered participating securities (i.e. unvested restricted stock), not subject to performance based measures. The following table sets forth the computation of basic and diluted earnings per common share: 2016 2015 2014 (In Thousands, Except Per Share Amounts) Basic Earnings Per Share: Net income available to common shareholders $ 28,843 $ 26,423 $ 24,292 Less: Income allocated to participating securities 39 8 4 Net income allocated to common shareholders 28,804 26,415 24,288 Weighted average common shares outstanding 8,980 9,221 9,511 Less: Participating securities 11 11 6 Average common shares 8,969 9,210 9,505 Basic earnings per common share $ 3.21 $ 2.87 $ 2.55 Diluted Earnings Per Share: Net income allocated to common shareholders $ 28,804 $ 26,415 $ 24,288 Weighted average common shares outstanding 8,969 9,210 9,505 Add: Dilutive effects of stock options 66 87 111 Add: Dilutive effects of warrants - 75 353 Average shares and dilutive potential common shares 9,035 9,371 9,969 Diluted earnings per common share $ 3.19 $ 2.82 $ 2.44 Shares subject to issue upon exercise of options of 12,550 8,750 10,500

The investment portfolio is evaluated for OTTI by segregating the portfolio into two general segments. Investment securities classified as available-for-sale or held-to-maturity are generally evaluated for OTTI under FASB ASC Topic 320. Certain collateralized debt obligations (“CDOs”) are evaluated for OTTI under FASB ASC Topic 325, Investment – Other When OTTI occurs under either model, the amount of the OTTI recognized in earnings depends on whether an entity intends to sell the security or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current period credit loss. If an entity intends to sell or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current period credit loss, the OTTI shall be recognized in earnings equal to the entire difference between the investment’s amortized cost basis and its fair value at the balance sheet date. If an entity does not intend to sell the security and it is not more likely than not that the entity will be required to sell the security before recovery of its amortized cost basis less any current period loss, the OTTI shall be separated into the amount representing the credit loss and the amount related to all other factors. The amount of OTTI related to the credit loss is determined based on the present value of cash flows expected to be collected compared to the book value of the security and is recognized in earnings. The amount of OTTI related to other factors shall be recognized in other comprehensive income, net of applicable taxes. The previous amortized cost basis less the OTTI recognized in earnings shall become the new amortized cost basis of the investment. With the exception of corporate bonds, the securities all have fixed interest rates, and all securities have defined maturities. Their fair value is sensitive to movements in market interest rates. First Defiance has the ability and intent to hold these investments for a time necessary to recover the amortized cost without impacting its liquidity position and it is not more than likely that the Company will be required to sell the investments before anticipated recovery. In 2016, 2015 and 2014, management determined there was no OTTI. In 2013, management determined that two CDOs had OTTI because they were disallowed under the Final Interim Volcker Rule of the Dodd-Frank Act released on January 14, 2014. The Company sold these two securities on January 15, 2014. There was no OTTI recognized in accumulated other comprehensive income (“AOCI”) relating to the CDOs at December 31, 2016 and 2015. 2016 2015 2014 Beginning balance, January 1 $ - $ - $ 3,513 Additions for amounts related to credit loss for which an OTTI was not previously recognized - - - Reductions for amounts realized for securities sold/redeemed during the period - - (3,513) Ending balance, December 31 $ - $ - $ - Realized gains from the sales and calls of investment securities totaled $ 509,000 331,000 22,000 15,000 932,000 652,000 2016 2015 2014 (In Thousands) Proceeds $ 14,871 $ 426 $ 14,913 Gross realized gains 509 22 1,574 Gross realized losses - - (642)

Commitments Contingencies and Guarantees [Text Block]	6. Commitments and Contingent Liabilities Loan Commitments Loan commitments are made to accommodate the financial needs of First Federal’s customers. Standby letters of credit commit the Company to make payments on behalf of customers when certain specified future events occur. They primarily are issued to facilitate customers’ trade transactions. Both arrangements have credit risk, essentially the same as that involved in extending loans to customers, and are subject to the Company’s normal credit policies. Collateral (e.g., securities, receivables, inventory and equipment) is obtained based on management’s credit assessment of the customer. 2016 2015 Fixed Rate Variable Rate Fixed Rate Variable Rate Commitments to make loans $ 34,432 $ 106,356 $ 80,862 $ 76,253 Unused lines of credit 14,384 400,542 31,991 323,171 Standby letters of credit - 9,668 - 19,632 Total $ 48,816 $ 516,566 $ 112,853 $ 419,056 Commitments to make loans are generally made for periods of 60 days or less.

The Company allocated $809,000 and $335,000, of specific reserves to those loans at December 31, 2016 and 2015, and committed to lend additional amounts totaling up to $20,000 and $48,000 at December 31, 2016 and 2015. The Company offers various types of concessions when modifying a loan, however, forgiveness of principal is rarely granted. Each TDR is uniquely designed to meet the specific needs of the borrower. Commercial and industrial loans modified in a TDR often involve temporary interest-only payments, term extensions, and converting revolving credit lines to term loans. Additional collateral or an additional guarantor is often requested when granting a concession. Commercial mortgage loans modified in a TDR often involve temporary interest-only payments, re-amortization of remaining debt in order to lower payments, and sometimes reducing the interest rate lower than the current market rate. Residential mortgage loans modified in a TDR are comprised of loans where monthly payments are lowered, either through interest rate reductions or principal only payments for a period of time, to accommodate the borrowers’ financial needs, interest is capitalized into principal, or the term and amortization are extended. Home equity modifications are made infrequently and usually involve providing an interest rate that is lower than the borrower would be able to obtain due to credit issues. All retail loans where the borrower is in bankruptcy are classified as TDRs regardless of whether or not a concession is made. Of the loans modified in a TDR, $6.2 million are on non-accrual status and partial charge-offs have in some cases been taken against the outstanding balance. Loans modified as a TDR may have the financial effect of increasing the allowance associated with the loan. If the loan is determined to be collateral dependent, the estimated fair value of the collateral, less any selling costs is used to determine if there is a need for a specific allowance or charge-off. If the loan is determined to be cash flow dependent, the allowance is measured based on the present value of expected future cash flows discounted at the loan’s pre-modification effective interest rate. The following table presents loans by class modified as TDRs that occurred during the years indicated (Dollars in Thousands): Loans Modified as a TDR for the Loans Modified as a TDR for the Loans Modified as a TDR for the TDRs Number of Recorded Number of Recorded Number of Recorded Residential Owner Occupied 17 $ 778 6 $ 454 18 $ 1,726 Residential Non Owner Occupied 5 494 4 59 3 517 Multi Family 2 1,885 - - - - CRE Owner Occupied - - 2 645 2 27 CRE Non Owner Occupied 5 974 2 244 3 403 Agriculture Land 1 45 3 1,443 - - Other CRE 1 348 - - - - Commercial Working Capital 1 226 2 62 4 1,353 Commercial Other 1 587 2 70 16 2,020 Home Equity and Home Improvement 9 281 13 324 17 471 Consumer Finance 2 14 9 62 4 15 Total 44 $ 5,632 43 $ 3,363 67 $ 6,532 The loans described above increased the allowance for loan losses (“ALLL”) by $413,000 for the year ended December 31, 2016, decreased the ALLL by $13,000 for the year ended December 31, 2015, and increased the ALLL by $234,000 for the year ended December 31, 2014. Of the 2016 modifications, fifteen were made TDRs due to the fact that the borrower filed bankruptcy, one was made a TDR due to an interest only period, six were made a TDR due to extending the maturity, five were made TDRs due to advancing or renewing funds to a watchlist credit, two were made TDRs to term out lines of credit, and fifteen were made TDRs to refinance current debt for payment relief.

They decreased the ALLL by $14,000 after $176,000 in charge-offs for the year ended December 31, 2014. A default for purposes of this disclosure is a TDR loan in which the borrower is 90 days contractually past due under the modified terms. The terms of certain other loans were modified during the periods ending December 31, 2016 and 2015 that did not meet the definition of a TDR. The modification of these loans involved a modification of the terms of a loan to borrowers who were not experiencing financial difficulties. A total of 373 loans were modified under this definition during the twelve month period ended December 31, 2016 and a total of 187 loans were modified under this definition during the twelve month period ended December 31, 2015. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed regarding the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. Credit Quality Indicators Loans are categorized into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. Loans are analyzed individually by classifying the loans as to credit risk. This analysis includes all non-homogeneous loans, such as commercial and commercial real estate loans and certain homogenous mortgage, home equity and consumer loans. This analysis is performed on a quarterly basis. First Defiance uses the following definitions for risk ratings: Special Mention. Loans classified as special mention have a potential weakness that deserves management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution's credit position at some future date. Substandard. Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Doubtful. Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, 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. Not Graded. Loans classified as not graded are generally smaller balance residential real estate, home equity and consumer installment loans which are originated primarily by using an automated underwriting system.

Regulatory Capital Requirements [Abstract]
Regulatory Capital Requirements under Banking Regulations [Text Block]	17. Regulatory Matters First Federal is subject to minimum capital adequacy guidelines. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators, which could have a material impact on First Federal’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, First Federal must maintain capital amounts in excess of specified minimum ratios based on quantitative measures of First Federal’s assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices.

Fair Value Disclosures [Abstract]
Fair Value, Measurement Inputs, Disclosure [Text Block]	22. Fair Value FASB ASC Topic 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The price in the principal (or most advantageous) market used to measure the fair value of the asset or liability shall not be adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities; it is not a forced transaction. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact and (iv) willing to transact. FASB ASC Topic 820 requires the use of valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. The income approach uses valuation techniques to convert future amounts, such as cash flows or earnings, to a single present amount on a discounted basis. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement cost). Valuation techniques should be consistently applied. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability developed based on the best information available. In that regard, FASB ASC Topic 820 established a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows: · Level 1 : Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. · Level 2 : Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by a correlation or other means. · Level 3 : Unobservable inputs for determining fair value of assets and liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities. A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. Available for sale securities - Securities classified as available for sale are generally reported at fair value utilizing Level 2 inputs where the Company obtains fair value measurements from an independent pricing service that uses matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows and the bonds’ terms and conditions, among other things. Securities in Level 1 include federal agency preferred stock securities. Securities in Level 2 include U.S. Government agencies, mortgage-backed securities, corporate bonds and municipal securities. Impaired loans - Fair values for impaired collateral dependent loans are generally based on appraisals obtained from licensed real estate appraisers and in certain circumstances consideration of offers obtained to purchase properties prior to foreclosure. Appraisals for commercial real estate generally use three methods to derive value: cost, sales or market comparison and income approach. The cost method bases value on the cost to replace the current property. Value of market comparison approach evaluates the sales price of similar properties in the same market area. The income approach considers net operating income generated by the property and an investors required return. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Comparable sales adjustments are based on known sales prices of similar type and similar use properties and duration of time that the property has been on the market to sell. Such adjustments made in the appraisal process are typically significant and result in a Level 3 classification of the inputs for determining fair value. Real Estate held for sale - Assets acquired through or instead of loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. These assets are then reviewed monthly by members of the asset review committee for valuation changes and are accounted for at lower of cost or fair value less estimated costs to sell. Fair value is commonly based on recent real estate appraisals which may utilize a single valuation approach or a combination of approaches including cost, comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments may be significant and typically result in a Level 3 classification of the inputs for determining fair value. Appraisals for both collateral-dependent impaired loans and other real estate owned are performed by certified general appraisers (for commercial properties) or certified residential appraisers (for residential properties) whose qualifications and licenses have been reviewed and verified by the Company. Once received, a member of the Company’s asset quality or collections department reviews the assumptions and approaches utilized in the appraisal. Appraisal values are discounted from 0 20 Mortgage servicing rights – On a quarterly basis, mortgage servicing rights are evaluated for impairment based upon the fair value of the rights as compared to the carrying amount. If the carrying amount of an individual tranche exceeds fair value, impairment is recorded on that tranche so that the servicing asset is carried at fair value. Fair value is determined at a tranche level based on a model that calculates the present value of estimated future net servicing income. The valuation model utilizes assumptions that market participants would use in estimating future net servicing income and are validated against available market data (Level 2). Mortgage banking derivative - The fair value of mortgage banking derivatives are evaluated monthly based on derivative valuation models using quoted prices for similar assets adjusted for specific attributes of the commitments and other observable market data at the valuation date (Level 2).

Since negotiated prices for the instruments, which are not readily marketable, depend greatly on the motivation of the buyer and seller, the amounts that will actually be realized or paid per settlement or maturity of these instruments could be significantly different. The carrying amount of cash and cash equivalents, term notes payable and advance payments by borrowers for taxes and insurance, as a result of their short-term nature, is considered to be equal to fair value and are classified as Level 1. It was not practicable to determine the fair value of FHLB stock due to restrictions placed on its transferability. The fair value of loans that reprice within 90 days is equal to their carrying amount. For other loans, the estimated fair value is calculated based on discounted cash flow analysis, using interest rates currently being offered for loans with similar terms, resulting in a Level 3 classification. Impaired loans are valued at the lower of cost or fair value as previously described. The allowance for loan losses is considered to be a reasonable adjustment for credit risk. The methods utilized to estimate the fair value of loans do not necessarily represent an exit price. The fair value of loans held for sale is estimated based on binding contracts and quotes from third party investors resulting in a Level 2 classification. The fair value of accrued interest receivable is equal to the carrying amounts resulting in a Level 2 or Level 3 classification, which is consistent with its underlying asset. The fair value of non-interest bearing deposits are considered equal to the amount payable on demand at the reporting date (i.e., carrying value) and are classified as Level 1. The fair value of savings, NOW and certain money market accounts are equal to their carrying amounts and are a Level 2 classification. Fair values of 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 time deposits resulting in a Level 2 classification. The fair values of securities sold under repurchase agreements are equal to their carrying amounts resulting in a Level 2 classification. The carrying value of subordinated debentures and deposits with fixed maturities is estimated based on discounted cash flow analyses based on interest rates currently being offered on instruments with similar characteristics and maturities resulting in a Level 3 classification.

Derivative Instruments and Hedging Activities Disclosure [Text Block]	23. Derivative Financial Instruments Commitments to fund certain mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of mortgage loans to third-party investors are considered derivatives. It is the Company’s practice to enter into forward commitments for the future delivery of residential mortgage loans when interest rate lock commitments are entered into in order to economically hedge the effect of changes in interest rates resulting from its commitments to fund the loans. These mortgage banking derivatives are not designated in hedge relationships.

Statement of Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of consolidated 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 amounts reported in the consolidated financial statements and accompanying notes. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ.
Earnings Per Share, Policy [Policy Text Block]	Earnings Per Common Share Basic earnings per common share is computed by dividing net income applicable to common shares (net income less dividend requirements for preferred stock, accretion of preferred stock discount and redemption of preferred stock) by the weighted average number of shares of common stock outstanding during the period. All outstanding unvested share-based payment awards that contain rights to nonforfeitable dividends are considered participating securities for the calculation. Diluted earnings per common share includes the dilutive effect of additional potential common shares issuable under stock options, warrants, restricted stock awards and stock grants. See also Note 4.
Comprehensive Income, Policy [Policy Text Block]	Comprehensive Income Comprehensive income consists of net income and other comprehensive income (loss). Other comprehensive income (loss) includes unrealized gains and losses on available-for-sale securities and the net unrecognized actuarial losses and unrecognized prior service costs associated with the Company’s Defined Benefit Postretirement Medical Plan. All items included in other comprehensive income are reported net of tax. See also Notes 5, 16 and 25 and the Consolidated Statements of Comprehensive Income.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash Flows Cash and cash equivalents include amounts due from banks and overnight investments with the Federal Home Loan Bank (“FHLB”) and the Federal Reserve. Cash and amounts due from depository institutions include required balances on hand or on deposit at the FHLB and Federal Reserve of approximately $ 1,809,000 1,896,000
Investment, Policy [Policy Text Block]	Investment Securities M anagement determines the appropriate classification of debt securities at the time of purchase and evaluates such designation as of each balance sheet date. Debt securities are classified as held-to-maturity when First Defiance has the positive intent and ability to hold the securities to maturity and are reported at cost, adjusted for premiums and discounts that are recognized in interest income using the interest method over the period to maturity. Debt securities not classified as held-to-maturity and equity securities are classified as available-for-sale. Available-for-sale securities are stated at fair value, with the unrealized gains and losses, net of tax, reported in other comprehensive income (loss) until realized. Realized gains and losses are included in gains (losses) on securities or other-than-temporary impairment losses on securities. Realized gains and losses on securities sold are recognized on the trade date based on the specific identification method. Interest income includes amortization of purchase premiums and discounts. Premiums and discounts are amortized on the level-yield method without anticipating prepayments, except for mortgage-backed securities where prepayments are expected. Securities with unrealized losses are reviewed quarterly to determine if value impairment is other–than-temporary. In performing this review management considers the length of time and extent that fair value has been less than cost, the financial condition of the issuer, the impact of changes in market interest rates on market value and whether the Company intends to sell or it would be more than likely required to sell the securities prior to their anticipated recovery. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: (1) other-than-temporary impairment (“OTTI”) related to credit loss, which must be recognized in the income statement and (2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of impairment is recognized through earnings.
Stock In Federal Home Loan Bank [Policy Text Block]	FHLB Stock First Federal is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income. At December 31, 2016, the Company held $ 13.8 5,000
Policy Loans Receivable, Policy [Policy Text Block]	Loans Receivable Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal amount outstanding, net of deferred loan fees and costs, purchase premiums and discounts and the allowance for loan losses. Deferred fees net of deferred incremental loan origination costs, are amortized to interest income generally over the contractual life of the loan using the interest method without anticipating prepayments. The recorded investment in loans includes accrued interest receivable and net deferred fees and costs and undisbursed loan amounts. Mortgage loans originated and intended for sale in the secondary market are classified as loans held for sale and are carried at the lower of aggregate cost or fair value, as determined by outstanding commitments from investors. Net unrealized losses, if any, are recorded as a valuation allowance and charged to earnings. Mortgage loans held for sale are generally sold with servicing rights retained. The carrying value of mortgage loans sold is reduced by the amount allocated to the servicing right. Gains or losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold. The Company may incur losses pertaining to loans sold to Fannie Mae and Freddie Mac but repurchased due to underwriting issues. Repurchase losses are recognized when the Company determines they are probable and estimable. Interest receivable is accrued on loans and credited to income as earned. The accrual of interest on loans 90 days delinquent or impaired is discontinued when, in management’s opinion, the borrower may be unable to meet payments as they become due. For these loans, interest accrual is only to the extent cash payments are received. The accrual of interest on these loans is generally resumed after a pattern of repayment has been established and the collection of principal and interest is reasonably assured.
Certain Loans and Debt Securities Acquired in Transfer, Recognizing Interest Income on Impaired Loans, Policy [Policy Text Block]	Acquired Loans The Company acquires loans individually and in groups or portfolios. At acquisition, the Company reviews each loan to determine whether there is evidence of deterioration of credit quality since origination and if it is probable that it will be unable to collect all amounts due according to the loan’s contractual terms. If both conditions exist, the Company determines whether each such loan is to be accounted for individually or whether such loans will be assembled into pools of loans based on common risk characteristics (credit score, loan type and date of origination). The Company considers expected prepayments, and estimates the amount and timing of undiscounted expected principal, interest, and other cash flows (expected at acquisition) for each loan and subsequently aggregated pool of loans. The Company determines the excess of the loan’s or pool’s scheduled contractual principal and contractual interest payments over all cash flows expected at acquisition as an amount that should not be accreted (nonaccretable difference). The remaining amount—representing the excess of the loan’s cash flows expected to be collected over the amount paid—is accreted into interest income over the remaining life of the loan or pool (accretable yield). Over the life of the loan or pool, the Company continues to estimate cash flows expected to be collected, and evaluates whether the present value of its loans determined using the effective interest rates has decreased and, if so, recognizes a loss. Valuation allowances for all acquired loans subject to FASB ASC Topic 310 reflect only those losses incurred after acquisition—that is, the present value of cash flows expected at acquisition that are not expected to be collected. The present value of any subsequent increase in the loan’s or pool’s actual cash flows or cash flows expected to be collected is used first to reverse any existing valuation allowance for that loan or pool. For any remaining increases in cash flows expected to be collected, the Company adjusts the amount of accretable yield recognized on a prospective basis over the loan’s or pool’s remaining life.
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	Allowance for Loan Losses The allowance for loan losses is maintained at a level believed adequate by management to absorb probable incurred losses in the loan portfolio and is based on the size and current risk characteristics of the loan portfolio, an assessment of individual problem loans, actual loss experience, current economic events in specific industries and geographical areas and other pertinent factors, including general economic conditions. Determination of the allowance is inherently subjective as it requires significant estimates, including the amounts and timing of expected future cash flows on impaired loans, estimated losses on pools of homogeneous loans based on historical loss experience and consideration of economic trends, all of which may be susceptible to significant change. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management’s judgment, should be charged off. Beginning June 30, 2015, the Company refined the methodology to its allowance for loan loss calculation pertaining to the general reserve component for non-impaired loans. There was no change to the calculation of the component for reserves on impaired loans. Within the general reserve, the determination of the historical loss component was modified from using a three-year average annual loss rate to a loss migration measurement. The loss migration measurement implemented June 30, 2015, utilized an average of four (4) four-year loss migration periods for each loan portfolio segment with differentiation between loan risk grades. Prior to June 30, 2015, the approach to this component quantified the historical loss by calculating a rolling twelve quarter average annual loss rate for each portfolio segment, without differentiation between loan risk grades. Beginning December 31, 2016 the historical loss calculation was changed from using an average of four (4) four-year loss migration periods to using an average of all four-year loss migration periods to the present beginning with data from the second quarter 2011. Management believes this enhancement is consistent with the rationale of the previous measurement but provides a more precise calculation of historical losses by incorporating more data points for the average loss ratio and including periods that provide a more complete coverage of the full business cycle. Management believes that capturing the risk grade changes and cumulative losses over the life cycle of a loan more accurately depicts management’s estimate of historical losses as well as being more reflective of the ongoing risks in the loan portfolio. These modifications resulted in a change in the general reserves between the loan portfolio segments but did not have a material impact on the overall allowance for loan losses. Loan losses are charged off against the allowance when in management’s estimation it is unlikely that the loan will be collected, while recoveries of amounts previously charged off are credited to the allowance. A provision for loan loss is charged to operations based on management’s periodic evaluation of the factors previously mentioned, as well as other pertinent factors in order to maintain the allowance for loan losses at the level deemed adequate by management. The determination of whether a loan is considered past due or delinquent is based on the contractual payment terms. Loans are considered past due when the contractual amounts due with respect to principal and interest are not received within 30 days of the contractual due date. All loans are placed on nonaccrual status at 90 days past due unless the loan is adequately secured and is in process of collection. Any loan in the portfolio may be placed on nonaccrual status prior to becoming 90 days past due when collection of principal or interest is in doubt. The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. Impaired loans have been recognized in conformity with FASB ASC Topic 310. A loan is impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loans agreement. Loans, for which terms have been modified and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings and classified as impaired. An analysis of the net present value of estimated cash flows is performed and an allowance may be established based on the outcome of that analysis, or if the loan is deemed to be collateral dependent an allowance is established based on the fair value of collateral. All modifications are reviewed by the First Federal’s Chief Credit Officer to determine whether or not the modification constitutes a troubled debt restructure. Commercial and commercial real estate loans are individually evaluated for impairment. If a loan is impaired, a portion of the allowance is allocated so that the loan is reported net of the allowance allocation which is determined based on the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the collateral. Large groups of smaller balance homogeneous loans, such as consumer and residential real estate loans, are collectively evaluated for impairment, and accordingly, they are not separately identified for impairment disclosures. The following portfolio segments have been identified: Commercial Real Estate Loans (consisting of multi-family residential and non-residential): Commercial real estate loans are subject to underwriting standards and processes similar to commercial and industrial loans. These loans are viewed primarily as cash flow loans and the repayment of these loans is largely dependent on the successful operation of the property. Loan performance may be adversely affected by factors impacting the general economy or conditions specific to the real estate market such as geographic location and/or property type. Commercial Loans : Commercial credit is extended primarily to middle market customers. Such credits are typically comprised of working capital loans, loans for physical asset expansion, asset acquisition loans and other business loans. Loans to closely held businesses will generally be guaranteed in full or for a meaningful amount by the businesses' principal owners. Commercial loans are made based primarily on the historical and projected cash flow of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not behave as forecasted and collateral securing loans may fluctuate in value due to economic or individual performance factors. Minimum standards and underwriting guidelines have been established for all commercial loan types. Consumer Finance Loans : Consumer finance loans are generally made to borrowers for a specific consumer purchase and are made based on their ability to repay with their current debt to income as well as the underlying collateral value of the item being purchased. Credit scores are part of the decision process of whether or not credit is extended. Minimum standards and underwriting guidelines have been established for all consumer loan types. 1-4 Family Residential Real Estate Loans : 1-4 family residential real estate loans can be categorized two different ways. One part of this portfolio is owner occupied and are made based primarily on the ability of the individual borrower to support the payments as well as the payments of any other debt the borrower may have outstanding at the time the loan is made. The other part of this portfolio is non-owner occupied income producing property and is made primarily based on the cash flow stream from rental income as well as the cash flow support from the borrower’s unrelated cash flow. Both types of loans have a secondary repayment source of the underlying collateral and generally the loans are not extended at higher than an 80% LTV. Minimum standards and underwriting guidelines have been established for all 1-4 family residential real estate loan types. Construction Loans : The Company defines construction loans as loans where the loan proceeds are controlled by the Company and used exclusively for the improvement of real estate in which the Company holds a mortgage. Home Equity and Improvement Loans : Home Equity and Improvement loans are made to borrowers based on their ability to repay with their current debt to income as well as the underlying collateral value of the real estate taken as security. Minimum standards and underwriting guidelines have been established for all 1-4 family residential real estate loan types. Consumer finance, 1-4 family residential real estate (including construction) and home equity and improvement loans are subject to adverse employment conditions in the local economy which could increase default rate on loans.
Transfers and Servicing of Financial Assets, Servicing of Financial Assets, Policy [Policy Text Block]	Servicing Rights Servicing rights are recognized separately when they are acquired through sales of loans. Servicing rights are initially recorded at fair value with the income statement effect recorded in gains on sales of loans. 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. The Company compares the valuation model inputs and results to published industry data in order to validate the model results and assumptions. All classes of servicing assets are subsequently measured using the amortization method which requires servicing rights to be amortized into non-interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans, driven, generally, by changes in market interest rates. Servicing assets are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. Impairment is determined by stratifying rights into groupings based on predominant risk characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. If the Company later determines that all or a portion of the impairment no longer exists for a particular grouping, a reduction of the allowance may be recorded as an increase to income. Changes in valuation allowances are reported with mortgage banking income on the income statement. The fair values of servicing rights are subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and default rates and losses. Servicing fee income, which is reported on the income statement with mortgage banking 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. Servicing fees totaled $ 3.6 3.5 3.6
Bank Owned Life Insurance [Policy Text Block]	Bank Owned Life Insurance The Company has purchased life insurance policies for certain key employees. Bank owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
Property, Plant and Equipment, Policy [Policy Text Block]	Premises and Equipment and Long Lived Assets Land is carried at cost. Premises and equipment are carried at cost less accumulated depreciation and amortization computed principally by the straight-line method over the following estimated useful lives: Buildings and improvements 20 to 50 years Furniture, fixtures and equipment 3 to 15 years Long-lived assets to be held and those to be disposed of and certain intangibles are periodically evaluated for impairment. See Note 9.
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill and Other Intangibles Goodwill resulting from business combinations prior to January 1, 2009 represents the excess of the purchase price over the fair value of the net assets of businesses acquired. Goodwill resulting from business combinations after January 1, 2009, is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually. The Company has selected November 30 as the date to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Goodwill is the only intangible asset with an indefinite life on First Defiance’s balance sheet. Other intangible assets consist of core deposit and acquired customer relationship intangible assets arising from whole bank, insurance and branch acquisitions. They are initially recorded at fair value and then amortized on an accelerated basis over their estimated lives, which range from five years for non-compete agreements to 10 20
Real Estate Held for Development and Sale, Policy [Policy Text Block]	Real Estate and Other Assets Held for Sale Real estate and other assets held for sale are comprised of properties or other assets acquired through foreclosure proceedings or acceptance of a deed in lieu of foreclosure. These assets are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. Losses arising from the acquisition of such property are charged against the allowance for loan losses at the time of acquisition. These properties are carried at the lower of cost or fair value, less estimated costs to dispose. If fair value declines subsequent to foreclosure, the property is written down against expense. Costs after acquisition are expensed.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock Compensation Plans Compensation cost is recognized for stock options and restricted share awards issued to employees and directors, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options. Restricted shares awards are valued at the market value of Company stock at the date of the grant. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award. See Note 20.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Value of Financial Instruments Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in Note 22. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect the estimates.
Transfers and Servicing of Financial Assets, Transfers of Financial Assets, Sales, Policy [Policy Text Block]	Transfers of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Loans and Leases Receivable, Mortgage Banking Activities, Policy [Policy Text Block]	Mortgage Banking Derivatives Commitments to fund mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of these mortgage loans are accounted for as free standing derivatives. Fair values of these mortgage derivatives are estimated based on changes in mortgage interest rates from the date the interest on the loan is locked. The Company enters into forward commitments for the future delivery of mortgage loans when interest rate locks are entered into, in order to hedge the change in interest rates resulting from its commitments to fund the loans. Changes in fair values of these derivatives are included in mortgage banking income.
Segment Reporting, Policy [Policy Text Block]	Operating Segments Management considers the following factors in determining the need to disclose separate operating segments: (1) The nature of products and services, which are all financial in nature. (2) The type and class of customer for the products and services; in First Defiance’s case retail customers for retail bank and insurance products and commercial customers for commercial loan, deposit, life, health and property and casualty insurance needs. (3) The methods used to distribute products or provide services; such services are delivered through banking and insurance offices and through bank and insurance customer contact representatives. Retail and commercial customers are frequently targets for both banking and insurance products. (4) The nature of the regulatory environment; both banking and insurance entities are subject to various regulatory bodies and a number of specific regulations. Quantitative thresholds as stated in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 280, Segment Reporting 9.2 4.9 0.6
Dividend Restriction [Policy Text Block]	Dividend Restriction Banking regulations require maintaining certain capital levels and may limit the dividends paid by the savings bank to the holding company. See Note 17 for further details on restrictions.
Loan Commitments, Policy [Policy Text Block]	Loan Commitments and Related Financial Instruments Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.
Malpractice Loss Contingency, Policy [Policy Text Block]	Loss Contingencies Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there are any such matters that will have a material effect on the financial statements.
Income Tax, Policy [Policy Text Block]	Income Taxes Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. Realization of deferred tax assets is dependent upon the generation of a sufficient level of future taxable income and recoverable taxes paid in prior years. Although realization is not assured, management believes it is more likely than not that all of the deferred tax assets will be realized. An effective tax rate of 35 A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The Company recognizes interest and/or penalties related to income tax matters in income tax expense.
Pension and Other Postretirement Plans, Pensions, Policy [Policy Text Block]	Retirement Plans Pension expense is the net of service and interest cost, return on plan assets and amortization of gains and losses not immediately recognized. Employee 401(k) plan expense is the amount of matching contributions. Deferred compensation and supplemental retirement plan expense allocates the benefits over years of service. See Note 16 and 19.
Reclassification, Policy [Policy Text Block]	Reclassifications Some items in the prior year financial statements were reclassified to conform to the current presentation.
New Accounting Pronouncements, Policy [Policy Text Block]	Accounting Standards Updates In August 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2016-05 — Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force). The amendments in this update provide guidance on eight specific cash flow issues. The new guidance is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The amendments in this update are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company does not believe this standard will have a material impact on its consolidated statements of cash flows. In June 2016, the FASB issued new accounting guidance in ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments (Topic 326). The main objective of the update is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this objective, the amendments in this update replace the incurred loss impairment methodology in current Generally Accepted Accounting Principles with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to form credit loss estimates. The amendments in this update become effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2019. The Company is currently evaluating the impact of this new accounting standard on the Company's consolidated financial statements. Management’s initial review indicates it has maintained sufficient historical loan data to support the requirement of this pronouncement and is currently evaluating the various loss methodologies to determine their correlations to the Company’s loan segments historical performance. In February 2016, the FASB issued ASU No. 2016-02 — Leases (Topic 842). The objective of the update is to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact this standard will have on its financial position and results of operations, though the Company expects that its real estate leases will be recognized on the consolidated balance sheet. In January 2016, the FASB issued ASU No. 2016-01 — Financial Instruments — Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this update address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The ASU is effective for fiscal years and interim periods within those years beginning after December 15, 2017, and requires a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. Early adoption is not permitted. The Company is currently evaluating the impact of adopting the new guidance on the consolidated financial statements. Management’s preliminary finding is that the new pronouncement will not have a significant impact on its results of operations. The pronouncement will require some revision to the Company’s disclosures within the consolidated financial statements and is currently evaluating the impact. In May 2014, the FASB issued ASU No. 2014-09 — Revenue from Contracts with Customers, and subsequently has issued five related accounting standard updates clarifying several aspects of ASU 2014-09, including technical corrections and improvements. The overall objective of the new standards updates is to provide a single, comprehensive revenue recognition model for all contracts with customers to improve comparability within industries, across industries, and across capital markets. The revenue standard contains principles that will be applied to determine the measurement of revenue and timing of when it is recognized. The Company anticipates adopting the new standard on its effective date, January 1, 2018, though the Company has not yet selected whether it would adopt using the retrospective approach with adjustments to each prior period or the retrospective method with the cumulative effect of initial application recognized at the date of initial application. While the Company is continuing to assess all potential impacts this standard will have on its financial position and results of operations, early conclusions indicate that these standards will not have a material impact. The implementation efforts include the identification of revenue within the scope of the guidance, as well as the evaluation of revenue contracts.
