Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Financial Statement Presentation	Note 1: Basis of Financial Statement Presentation IF Bancorp, Inc., a Maryland corporation (the “Company”), became the holding company for Iroquois Federal Savings and Loan Association (the “Association”) upon completion of the Association’s conversion on July 7, 2011. At the time of the conversion, the Company sold shares of its common stock to the public and also established an employee stock ownership plan that purchased 384,900 shares of Company stock, and a charitable foundation, Iroquois Federal Foundation, to which the Company donated 314,755 shares of Company stock and $450,000 cash. IF Bancorp, Inc.’s common stock trades on the NASDAQ Capital Market under the symbol “IROQ”. In December 2017, the Tax Cuts and Jobs Act was enacted, which will lower our federal income tax rate to 21% effective for tax periods after December 31, 2017. As a result, the Company is required to revalue its deferred tax assets and deferred tax liabilities to account for the future impact of the lower corporate rate on these deferred amounts. The effect of the change in tax rates on our deferred tax assets and liabilities is recognized as an expense in the period that includes the enactment date, which is the quarter ended December 31, 2017. The one-time The unaudited condensed consolidated financial statements include the accounts of the Company, the Association, and the Association’s wholly owned subsidiary, L.C.I. Service Corporation. All significant intercompany accounts and transactions have been eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial reporting and with instructions for Form 10–Q and Regulation S–X. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the balance sheet date and revenues and expenses for the period. Actual results could differ from these estimates. In the opinion of management, the preceding unaudited condensed consolidated financial statements contain all adjustments (consisting only of normal recurring accruals) necessary for a fair presentation of the financial condition of the Company as of December 31, 2017 and June 30, 2017, and the results of its operations for the three month and six month periods ended December 31, 2017 and 2016. These consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-based Compensation	Note 3: Stock-based Compensation In connection with the conversion to stock form, the Association established an ESOP for the exclusive benefit of eligible employees (all salaried employees who have completed at least 1,000 hours of service in a twelve-month period and have attained the age of 21). The ESOP borrowed funds from the Company in an amount sufficient to purchase 384,900 shares (approximately 8% of the common stock issued in the stock offering). The loan is secured by the shares purchased and will be repaid by the ESOP with funds from contributions made by the Association and dividends received by the ESOP, with funds from any contributions on ESOP assets. Contributions will be applied to repay interest on the loan first, then the remainder will be applied to principal. The loan is expected to be repaid over a period of up to 20 years. Shares purchased with the loan proceeds are held in a suspense account for allocation among participants as the loan is repaid. Contributions to the ESOP and shares released from the suspense account are allocated among participants in proportion to their compensation, relative to total compensation of all active participants. Participants will vest 100% in their accrued benefits under the employee stock ownership plan after six vesting years, with prorated vesting in years two through five. Vesting is accelerated upon retirement, death or disability of the participant or a change in control of the Association. Forfeitures will be reallocated to remaining plan participants. Benefits may be payable upon retirement, death, disability, separation from service, or termination of the ESOP. Since the Association’s annual contributions are discretionary, benefits payable under the ESOP cannot be estimated. Participants receive the shares at the end of employment. The Company is accounting for its ESOP in accordance with ASC Topic 718, Employers Accounting for Employee Stock Ownership Plans A summary of ESOP shares at December 31, 2017 and June 30, 2017 are as follows (dollars in thousands): December 31, 2017 June 30, 2017 Allocated shares 96,133 83,004 Shares committed for release 9,622 19,245 Unearned shares 259,808 269,430 Total ESOP shares 365,563 371,679 Fair value of unearned ESOP shares (1) $ 5,108 $ 5,294 (1) Based on closing price of $19.66 and $19.50 per share on December 31, 2017, and June 30, 2017, respectively. During the six months ended December 31, 2017, 6,116 ESOP shares were paid to ESOP participants due to separation from service. During the six months ended December 31, 2016, 7,360 ESOP shares were paid to ESOP participants due to separation from service. At the annual meeting on November 19, 2012, the IF Bancorp, Inc. 2012 Equity Incentive Plan (the “Equity Incentive Plan”) was approved by stockholders. The purpose of the Equity Incentive Plan is to promote the long-term financial success of the Company and its Subsidiaries by providing a means to attract, retain and reward individuals who contribute to such success and to further align their interests with those of the Company’s stockholders. The Equity Incentive Plan authorizes the issuance or delivery to participants of up to 673,575 shares of the Company common stock pursuant to grants of incentive and non-qualified On December 10, 2013, the Board of Directors approved grants of 85,500 shares of restricted stock and 167,000 in stock options to senior officers and directors of the Association. The restricted stock vests in equal installments over 10 years and the stock options vest in equal installments over 7 years. Vesting of both the restricted stock and options started in December 2014. On December 10, 2015, the Board of Directors approved grants of 16,900 shares of restricted stock to be awarded to senior officers and directors of the Association. The restricted stock vests in equal installments over 8 years, starting in December 2016. As of December 31, 2016, there were 90,050 shares of restricted stock and 314,125 stock option shares available for future grants under this plan.

Securities	Note 5: Securities The amortized cost and approximate fair value of securities, together with gross unrealized gains and losses, of securities are as follows: Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value Available-for-sale December 31, 2017: U.S. Government and federal agency and Government sponsored enterprises (GSE’s) $ 16,134 $ 1 $ (197 ) $ 15,938 Mortgage-backed: GSE residential 97,018 202 (1,387 ) 95,833 Small Business Administration 2,009 — (25 ) 1,984 State and political subdivisions 2,981 239 — 3,220 $ 118,142 $ 442 $ (1,609 ) $ 116,975 June 30, 2017: U.S. Government and federal agency and Government sponsored enterprises (GSE’s) $ 25,230 $ 39 $ (234 ) $ 25,035 Mortgage-backed: GSE residential 81,088 372 (498 ) 80,962 Small Business Administration 2,048 — (16 ) 2,032 State and political subdivisions 3,274 308 — 3,582 $ 111,640 $ 719 $ (748 ) $ 111,611 With the exception of U.S. Government, federal agency and GSE securities and GSE residential mortgage-backed securities with a book value of approximately $16,134,000 and $97,018,000, respectively, and a market value of approximately $15,938,000 and $95,833,000, respectively, at December 31, 2017, the Company held no securities at December 31, 2017 with a book value that exceeded 10% of total equity. All mortgage-backed securities at December 31, 2017 and June 30, 2017 were issued by GSEs.

The carrying value of securities sold under agreement to repurchase amounted to $3.0 million at December 31, 2017 and $2.2 million at June 30, 2017. At December 31, 2017, approximately $1.2 million of our repurchase agreements had an overnight maturity, while the remaining $1.8 million in repurchase agreements had a term of 30 to 90 days. All of our repurchase agreements were secured by U.S. Government, federal agency and GSE securities. The right of offset for a repurchase agreement resembles a secured borrowing, whereby the collateral pledged by the Company would be used to settle the fair value of the repurchase agreement should the Company be in default. The collateral is held by the Company in a segregated custodial account. In the event the collateral fair value falls below stipulated levels, the Company will pledge additional securities. The Company closely monitors collateral levels to ensure adequate levels are maintained. Gross gains of $20,000 and $117,000, and gross losses of $7,000 and $0, resulting from sales of available-for-sale available-for-sale Certain investments in debt securities are reported in the consolidated financial statements at an amount less than their historical cost. Total fair value of these investments at December 31, 2017 and June 30, 2017, was $101,790,000 and $75,046,000, respectively, which is approximately 87% and 67% of the Company’s available-for-sale The following table shows the Company’s gross unrealized investment losses and the fair value of the Company’s investments with unrealized losses that are not deemed to be other-than-temporarily impaired, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position at December 31, 2017 and June 30, 2017: Less Than 12 Months 12 Months or More Total Description of Securities Fair Value Unrealized Fair Value Unrealized Fair Value Unrealized December 31, 2017: U.S. Government and federal agency and Government sponsored enterprises (GSE’s) $ 6,055 $ (21 ) $ 8,602 $ (176 ) $ 14,657 $ (197 ) Mortgage-backed: GSE residential 65,875 (958 ) 19,274 (429 ) 85,149 (1,387 ) Small Business Administration 1,984 (25 ) — — 1,984 (25 ) Total temporarily impaired securities $ 73,914 $ (1,004 ) $ 27,876 $ (605 ) $ 101,790 $ (1,609 ) June 30, 2017: U.S. Government and federal agency and Government sponsored enterprises (GSE’s) $ 16,717 $ (234 ) $ — $ — $ 16,717 $ (234 ) Mortgage-backed: GSE residential 56,297 (498 ) — — 56,297 (498 ) Small Business Administration 2,032 (16 ) — — 2,032 (16 ) Total temporarily impaired securities $ 75,046 $ (748 ) $ — $ — $ 75,046 $ (748 ) The unrealized losses on the Company’s investment in residential mortgage-backed securities and U.S. Government and federal agency and Government sponsored enterprises at December 31, 2017 and June 30, 2017, are mostly the result of a decline in market value that is attributable to changes in interest rates and not credit quality, and the Company does not consider those investments to be other-than-temporarily impaired at December 31, 2017 and June 30, 2017.

Recognizing the Company’s obligations to its depositors and to the communities it serves, authorized personnel are expected to seek to develop and make sound, profitable loans that resources permit and that opportunity affords. The Company maintains lending policies and procedures designed to focus our lending efforts on the types, locations, and duration of loans most appropriate for our business model and markets. The Company’s principal lending activity is the origination of one- Management reviews and approves the Company’s lending policies and procedures on a routine basis. Management routinely (at least quarterly) reviews our allowance for loan losses and reports related to loan production, loan quality, concentrations of credit, loan delinquencies and non-performing The Company’s policies and loan approval limits are established by the Board of Directors. The loan officers generally have authority to approve one- one- one- The Company conducts internal loan reviews that validate the loans against the Company’s loan policy quarterly for mortgage, consumer, and small commercial loans on a sample basis, and all larger commercial loans on an annual basis. The Company also receives independent loan reviews performed by a third party on larger commercial loans to be performed annually. In addition to compliance with our policy, the third party loan review process reviews the risk assessments made by our credit department, lenders and loan committees. Results of these reviews are presented to management and the Board of Directors. The Company’s lending can be summarized into six primary areas: one- One- The Company offers one- non-conforming one- one- The Company offers USDA Rural Development loans and sells the servicing. In addition, the Company also offers home equity loans that are secured by a second mortgage on the borrower’s primary or secondary residence. Home equity loans are generally underwritten using the same criteria used to underwrite one- As one- one- Commercial Real Estate and Multi-Family Real Estate Loans Commercial real estate mortgage loans are primarily secured by office buildings, owner-occupied businesses, strip mall centers, churches and farm loans secured by real estate. In underwriting commercial real estate and multi-family real estate loans, the Company considers a number of factors, which include the projected net cash flow to the loan’s debt service requirement, the age and condition of the collateral, the financial resources and income level of the borrower and the borrower’s experience in owning or managing similar properties. Personal guarantees are typically obtained from commercial real estate and multi-family real estate borrowers. In addition, the borrower’s financial information on such loans is monitored on an ongoing basis by requiring periodic financial statement updates. The repayment of these loans is primarily dependent on the cash flows of the underlying property. However, the commercial real estate loan generally must be supported by an adequate underlying collateral value. The performance and the value of the underlying property may be adversely affected by economic factors or geographical and/or industry specific factors. These loans are subject to other industry guidelines that are closely monitored by the Company. Home Equity Lines of Credit In addition to traditional one- one- Commercial Business Loans The Company originates commercial non-mortgage medium-sized The commercial business loan portfolio consists primarily of secured loans. When making commercial business loans, the Company considers the financial statements, lending history and debt service capabilities of the borrower, the projected cash flows of the business and the value of any collateral. The cash flows of the underlying borrower, however, may not perform consistently with historical or projected information. Further, the collateral securing loans may fluctuate in value due to individual economic or other factors. Loans are typically guaranteed by the principals of the borrower. The Company has established minimum standards and underwriting guidelines for all commercial loan types. Real Estate Construction Loans The Company originates construction loans for one- Consumer Loans Consumer loans consist of installment loans to individuals, primarily automotive loans. These loans are underwritten utilizing the borrower’s financial history, including the Fair Isaac Corporation (“FICO”) Loan-to-value Loan Concentration The loan portfolio includes a concentration of loans secured by commercial real estate properties amounting to $240,106,000 and $227,359,000 as of December 31, 2017 and June 30, 2017, respectively. Generally, these loans are collateralized by multi-family and nonresidential properties. The loans are expected to be repaid from cash flows or from proceeds from the sale of the properties of the borrower. Purchased Loans and Loan Participations The Company’s loans receivable included purchased loans of $6,508,000 and $7,599,000 at December 31, 2017 and June 30, 2017, respectively. All of these purchased loans are secured by single family homes located out of our primary market area, but still primarily in the Midwest. The Company’s loans receivable also include commercial loan participations of $32,501,000 and $38,531,000 at December 31, 2017 and June 30, 2017, respectively, of which $9,082,000 and $10,322,000, at December 31, 2017 and June 30, 2017 were outside our primary market area.

23,501 $ 53,303 $ 8,182 $ 437,885 Management’s opinion as to the ultimate collectability of loans is subject to estimates regarding future cash flows from operations and the value of property, real and personal, pledged as collateral. These estimates are affected by changing economic conditions and the economic prospects of borrowers. The allowance for loan losses represents an estimate of the amount of losses believed inherent in our loan portfolio at the balance sheet date. The allowance calculation involves a high degree of estimation that management attempts to mitigate through the use of objective historical data where available. Loan losses are charged against the allowance for loan losses when management believes the uncollectability of the loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Overall, we believe the reserve to be consistent with prior periods and adequate to cover the estimated losses in our loan portfolio. The Company’s methodology for assessing the appropriateness of the allowance for loan losses consists of two key elements: (1) specific allowances for estimated credit losses on individual loans that are determined to be impaired through the Company’s review for identified problem loans; and (2) a general allowance based on estimated credit losses inherent in the remainder of the loan portfolio. The specific allowance is measured by determining the present value of expected cash flows, the loan’s observable market value, or, for collateral-dependent loans, the fair value of the collateral adjusted for market conditions and selling expense. Factors used in identifying a specific problem loan include: (1) the strength of the customer’s personal or business cash flows; (2) the availability of other sources of repayment; (3) the amount due or past due; (4) the type and value of collateral; (5) the strength of the collateral position; (6) the estimated cost to sell the collateral; and (7) the borrower’s effort to cure the delinquency. In addition for loans secured by real estate, the Company also considers the extent of any past due and unpaid property taxes applicable to the property serving as collateral on the mortgage. The Company establishes a general allowance for loans that are not deemed impaired to recognize the inherent losses associated with lending activities, but which, unlike specific allowances, has not been allocated to particular problem assets. The general valuation allowance is determined by segregating the loans by loan category and assigning allowance percentages based on the Company’s historical loss experience and management’s evaluation of the collectability of the loan portfolio. The allowance is then adjusted for qualitative factors that, in management’s judgment, affect the collectability of the portfolio as of the evaluation date. These qualitative factors may include: (1) Management’s assumptions regarding the minimal level of risk for a given loan category; (2) changes in lending policies and procedures, including changes in underwriting standards, and charge-off non-accrual re-evaluated Although the Company’s policy allows for a general valuation allowance on certain smaller-balance, homogenous pools of loans classified as substandard, the Company has historically evaluated every loan classified as substandard, regardless of size, for impairment as part of the review for establishing specific allowances. The Company’s policy also allows for general valuation allowance on certain smaller-balance, homogenous pools of loans which are loans criticized as special mention or watch. A separate general allowance calculation is made on these loans based on historical measured weakness, and which is no less than twice the amount of the general allowance calculated on the non-classified There have been no changes to the Company’s accounting policies or methodology from the prior periods. The Company categorizes loans 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. All loans are graded at inception of the loan. Subsequently, analyses are performed on an annual basis and grade changes are made as necessary. Interim grade reviews may take place if circumstances of the borrower warrant a more timely review. The Company utilizes an internal asset classification system as a means of reporting problem and potential problem loans. Under the Company’s risk rating system, the Company classifies problem and potential problem loans as “Watch,” “Substandard,” “Doubtful,” and “Loss.” The Company uses the following definitions for risk ratings: Pass – Watch – Substandard – Doubtful – Loss – charged-off. Risk characteristics applicable to each segment of the loan portfolio are described as follows.

Banking and Thrift [Abstract]
Regulatory Capital	Note 11: Regulatory Capital The federal banking agencies have adopted regulations that substantially amend the capital regulations currently applicable to us. These regulations implement the Basel III regulatory capital reforms and changes required by the Dodd-Frank Act. Effective January 1, 2015 (with some changes transitioned into full effectiveness over two to four years), the Association became subject to new capital requirements adopted by the OCC. These new requirements create a new required ratio for common equity Tier 1 (“CETI”) capital, increase the leverage and Tier 1 capital ratios, change the risk weight of certain assets for purposes of the risk-based capital ratios, create an additional capital conservation buffer over the required capital ratios, and change what qualifies as capital for purposes of meeting these various capital requirements. Beginning in 2016, failure to maintain the required capital conservation buffer would limit the ability of the Association to pay dividends, repurchase shares, or pay discretionary bonuses. The Company is exempt from consolidated capital requirements as those requirements do not apply to certain small savings and loan holding companies with assets under $1 billion. Under the new capital regulations, the minimum capital ratios are: (1) CETI capital ratio of 4.5% of risk-weighted assets; (2) a Tier 1 capital ratio of 6.0% of risk-weighted assets; (3) a total capital ratio of 8.0% of risk-weighted assets; and (4) a leverage ratio of 4.0%. CETI generally consists of common stock and retained earnings, subject to applicable regulatory adjustments and deductions. There are a number of changes in what constitutes regulatory capital, some of which are subject to transition periods. These changes include the phasing-out opt-out opt-out The new requirements also include changes in the risk-weights of assets to better reflect credit risk and other risk exposures. These include a 150% risk weight (increased from 100%) for certain high volatility commercial real estate acquisition, development and construction loans and for non-residential non-accrual In addition to the minimum CETI, Tier 1 and total capital ratios, the Association will have to maintain a capital conservation buffer consisting of additional CETI capital greater than 2.5% of risk-weighted assets above the required minimum levels in order to avoid limitations on paying dividends, engaging in share repurchases, and paying discretionary bonuses based on percentages of eligible retained income that could be utilized for such actions. This new capital conservation buffer requirement began in January 2016, at the 0.625% level, is now 1.875% and will be fully implemented in January 2019.

Fair Value Disclosures [Abstract]
Disclosures About Fair Value of Assets	Note 12: Disclosures About Fair Value of Assets Fair value is the price that would be received to sell an asset in an orderly transaction between market participants at the measurement date. Fair value measurements must maximize the use of observable inputs and minimize the use of unobservable inputs. There is a hierarchy of three levels of inputs that may be used to measure fair value: Level 1 Quoted prices in active markets for identical assets Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar assets; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets Recurring Measurements The following table presents the fair value measurements of assets recognized in the accompanying balance sheets measured at fair value on a recurring basis and the level within the fair value hierarchy in which the fair value measurements fall at December 31, 2017 and June 30, 2017: Fair Value Measurements Using Fair Value Quoted (Level 1) Significant (Level 2) Significant (Level 3) December 31, 2017: Available-for-sale U.S. Government and federal agency and Government sponsored enterprises (GSE’s) $ 15,938 $ — $ 15,938 $ — Mortgage-backed: GSE residential 95,833 — 95,833 — Small Business Administration 1,984 — 1,984 — State and political subdivisions 3,220 — 3,220 — Mortgage servicing rights 730 — — 730 Fair Value Measurements Using Fair Value Quoted (Level 1) Significant (Level 2) Significant (Level 3) June 30, 2017: Available-for-sale U.S. Government and federal agency and Government sponsored enterprises (GSE’s) $ 25,035 $ — $ 25,035 $ — Mortgage-backed: GSE residential 80,962 — 80,962 — Small Business Administration 2,032 — 2,032 — State and political subdivisions 3,582 — 3,582 — Mortgage servicing rights 710 — — 710 Following is a description of the valuation methodologies and inputs used for assets measured at fair value on a recurring basis and recognized in the accompanying balance sheets, as well as the general classification of such assets pursuant to the valuation hierarchy. There have been no significant changes in the valuation techniques during the period ended December 31, 2017. For assets classified within Level 3 of the fair value hierarchy, the process used to develop the reported fair value is described below. Available-for-Sale Where quoted market prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. There were no Level 1 securities as of December 31, 2017 or June 30, 2017. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics or discounted cash flows. For these investments, the inputs used by the pricing service to determine fair value may include one, or a combination of, observable inputs such as benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided Mortgage Servicing Rights Mortgage servicing rights do not trade in an active, open market with readily observable prices. Accordingly, fair value is estimated using discounted cash flow models. Due to the nature of the valuation inputs, mortgage servicing rights are classified within Level 3 of the hierarchy. Level 3 Reconciliation The following is a reconciliation of the beginning and ending balances of recurring fair value measurements recognized in the accompanying balance sheet using significant unobservable (Level 3) inputs: Mortgage Balance, July 1, 2017 $ 710 Total realized and unrealized gains and losses included in net income (2 ) Servicing rights that result from asset transfers 85 Payments received and loans refinanced (63 ) Balance, December 31, 2017 $ 730 Total gains or losses for the period included in net income attributable to the change in unrealized gains or losses related to assets and liabilities still held at the reporting date $ (2 ) Realized and unrealized gains and losses for items reflected in the table above are included in net income in the consolidated statements of income as noninterest income. Nonrecurring Measurements The following table presents the fair value measurement of assets measured at fair value on a nonrecurring basis and the level within the fair value hierarchy in which the fair value measurements fall at December 31, 2017 and June 30, 2017: Fair Value Measurements Using Fair Value Quoted Prices in (Level 1) Significant (Level 2) Significant (Level 3) December 31, 2017: Impaired loans (collateral-dependent) $ — $ — $ — $ — June 30, 2017: Impaired loans (collateral-dependent) $ 6,287 $ — $ — $ 6,287 The following table presents (losses)/recoveries recognized on assets measured on a non-recurring Three Months Ended December 31, Six Months Ended December 31, 2017 2016 2017 2016 Impaired loans (collateral-dependent) $ 2 $ (47 ) $ 1 $ (44 ) Following is a description of the valuation methodologies used for assets measured at fair value on a nonrecurring basis and recognized in the accompanying balance sheets, as well as the general classification of such assets pursuant to the valuation hierarchy. For assets classified within Level 3 of the fair value hierarchy, the process used to develop the reported fair value is described below. Collateral-dependent Impaired Loans, Net of the Allowance for Loan Losses The estimated fair value of collateral-dependent impaired loans is based on the appraised fair value of the collateral, less estimated cost to sell. Collateral-dependent impaired loans are classified within Level 3 of the fair value hierarchy. The Company considers the appraisal or evaluation as the starting point for determining fair value and then considers other factors and events in the environment that may affect the fair value. Appraisals of the collateral underlying collateral-dependent loans are obtained when the loan is determined to be collateral-dependent and subsequently as deemed necessary by the senior lending officer. Appraisals are reviewed for accuracy and consistency by the senior lending officer. Appraisers are selected from the list of approved appraisers maintained by management. The appraised values are reduced by discounts to consider lack of marketability and estimated cost to sell if repayment or satisfaction of the loan is dependent on the sale of the collateral. These discounts and estimates are developed by the senior lending officer by comparison to historical results. Unobservable (Level 3) Inputs The following tables present quantitative information about unobservable inputs used in recurring and nonrecurring Level 3 fair value measurements at December 31, 2017 and June 30, 2017. Fair Value at Valuation Technique Unobservable Inputs Range (Weighted Average) Mortgage servicing rights $ 730 Discounted cash Discount rate 9.5% – 10.5% (9.5%) Constant prepayment 9.4% - 29.9% (9.8%) Probability of default 0.00% - 0.32% (0.31%) Fair Value at Valuation Technique Unobservable Inputs Range (Weighted Average) Mortgage servicing rights $ 710 Discounted cash Discount rate 9.5% – 10.5% (9.5%) Constant prepayment 9.5% - 31.1% (9.6%) Probability of default 0.00% - 0.32% (0.31%) Impaired loans (collateral-dependent) 6,287 Market comparable properties Marketability discount 7.0% (7.0%) Fair Value of Financial Instruments The following tables present estimated fair values of the Company’s financial instruments and the level within the fair value hierarchy in which the fair value measurements fall at December 31, 2017 and June 30, 2017.

Cash and Cash Equivalents, Interest-Bearing Time Deposits in Banks, Federal Home Loan Bank Stock, Accrued Interest Receivable, Repurchase Agreements, Accrued Interest Payable and Advances from Borrowers for Taxes and Insurance The carrying amount approximates fair value. Loans The fair value of loans is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. Loans with similar characteristics were aggregated for purposes of the calculations. Deposits Deposits include demand deposits, savings accounts, NOW accounts and certain money market deposits. The carrying amount of these types of deposits approximates fair value. The fair value of fixed-maturity time deposits is estimated using a discounted cash flow calculation that applies the rates currently offered for deposits of similar remaining maturities. Federal Home Loan Bank Advances Rates currently available to the Company for debt with similar terms and remaining maturities are used to estimate the fair value of existing debt. Commitments to Originate Loans and Lines of Credit The fair value of commitments to originate loans is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties. For fixed-rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair values of lines of credit are based on fees currently charged for similar agreements, or on the estimated cost to terminate or otherwise settle the obligations with the counterparties at the reporting date.
