Organization, Consolidation and Presentation of Financial Statements [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations First Savings Financial Group, Inc. (the “Company”) is a financial holding company and the parent of First Savings Bank (the “Bank”) and First Savings Insurance Risk Management, Inc. (the “Captive”). The Bank, which is a wholly-owned Indiana-chartered commercial bank subsidiary of the Company, provides a variety of banking services to individuals and business customers through 16 locations in southern Indiana. The Bank attracts deposits primarily from the general public and uses those funds, along with other borrowings, primarily to originate residential mortgage, commercial mortgage, construction, commercial business and consumer loans, and to a lesser extent, to invest in mortgage-backed securities and other securities. The Bank has two wholly owned subsidiaries: First Savings Investments, Inc., a Nevada corporation that manages a securities portfolio and Southern Indiana Financial Corporation, which is currently inactive. At September 30, 2016, the Bank had a third wholly owned subsidiary, FFCC, Inc. (“FFCC”), which was an Indiana corporation that participated in commercial real estate development and leasing. In accordance with the Plan of Complete Liquidation adopted by FFCC’s board of directors and approval by the Bank as its sole shareholder on December 21, 2016, FFCC voluntarily dissolved and completely liquidated effective December 31, 2016. As a result of the liquidation, FFCC distributed its net assets to the Bank on December 31, 2016. On April 25, 2017, the Bank formed Q2 Business Capital, LLC (“Q2”), which is an Indiana limited liability company that specializes in the origination and servicing of U.S. Small Business Administration (“SBA”) loans. The Bank owns 51% of Q2 with the option to purchase the minority interest between July 1, 2020 and September 30, 2020. In accordance with Q2’s operating agreement, the Bank was allocated the first $1.7 million of cumulative net income of Q2 with any additional profits and losses allocated 51% to the Bank and 49% to Q2’s minority members. The Captive, which is a wholly-owned insurance subsidiary of the Company, is a Nevada corporation that provides property and casualty insurance to the Company, the Bank and the Bank’s active subsidiaries. In addition, the Captive provides reinsurance to 11 other third-party insurance captives for which insurance may not be currently available or economically feasible in the insurance marketplace. Basis of Consolidation and Reclassifications The consolidated financial statements include the accounts of the Company and its subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America and conform to general practices within the banking industry. Intercompany balances and transactions have been eliminated. Certain prior year amounts have been reclassified to conform to the current year presentation. The reclassifications had no effect on net income or stockholders’ equity. Statements of Cash Flows For purposes of the statements of cash flows, the Company has defined cash and cash equivalents as cash on hand, amounts due from banks (including cash items in process of clearing), interest-bearing deposits with other banks having an original maturity of 90 days or less and money market funds. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses and the valuation of real estate and other assets acquired in connection with foreclosures or in satisfaction of loans. In connection with the determination of the allowances for loan losses and the valuation of other real estate owned, management obtains independent appraisals for significant properties. A substantial portion of the Bank’s loan portfolio consists of single-family residential and commercial real estate loans to customers in the southern Indiana and Louisville, Kentucky metropolitan area. Accordingly, the ultimate collectability of a substantial portion of the Bank’s loan portfolio and the recovery of the carrying amount of other real estate owned are susceptible to changes in local market conditions. While management uses available information to recognize losses on loans and other real estate owned, further reductions in the carrying amounts of loans and other real estate owned may be necessary based on changes in local economic conditions. In addition, regulatory agencies, as an integral part of their examination process, periodically review the estimated losses on loans and other real estate owned. Such agencies may require the Company to recognize additional losses based on their judgments about information available to them at the time of their examination. Because of these factors, it is reasonably possible the estimated losses on loans and other real estate owned may change materially in the near term. However, the amount of the change that is reasonably possible cannot be estimated. Investment Securities Trading Account Securities : Securities purchased with the intention of recognizing short-term profits or which are actively bought and sold are classified as trading account securities and reported at fair value. The net realized and unrealized gains and losses on trading account securities are reported in noninterest income. Realized gains and losses on trading account securities are determined using the specific identification method. Securities Available for Sale : Securities available for sale consist primarily of municipal obligations, mortgage-backed securities and collateralized mortgage obligations (“CMOs”), and are stated at fair value. The Company holds municipal bonds issued by municipal governments within the U.S.; mortgage-backed securities and CMOs issued by the Government National Mortgage Association (“GNMA”), a U.S. government agency, and the Federal National Mortgage Association (“FNMA”) and the Federal Home Loan Mortgage Corporation (“FHLMC”), government-sponsored enterprises; debt securities issued by government-sponsored enterprises; and privately-issued CMOs and asset-backed securities (“ABSs”). The Company also holds pass-through asset-backed securities guaranteed by the SBA representing participating interests in pools of long-term debentures issued by state and local development companies certified by the SBA. Mortgage-backed securities represent participating interests in pools of long-term first mortgage loans originated and serviced by issuers of the securities. CMOs and ABSs are complex mortgage-backed securities that restructure the cash flows and risks of the underlying mortgage collateral. Amortization of premiums and accretion of discounts are recognized in interest income using methods approximating the interest method over the period to maturity, adjusted for anticipated prepayments. Unrealized gains and losses, net of tax, on securities available for sale are included in other comprehensive income and the accumulated unrealized holding gains and losses are reported as a separate component of equity until realized. Realized gains and losses on the sale of securities available for sale are determined using the specific identification method and are included in other noninterest income and, when applicable, are reported as a reclassification adjustment, net of tax, in other comprehensive income. Securities Held to Maturity : Debt securities for which the Company has the positive intent and ability to hold to maturity are reported at cost, adjusted for amortization of premiums and accretion of discounts that are recognized in interest income using methods approximating the interest method over the period to maturity, adjusted for anticipated prepayments. The Company classifies certain mortgage-backed securities and municipal obligations as held to maturity. Declines in the fair value of individual available for sale and held to maturity securities below their amortized cost that are other than temporary result in write-downs of the individual securities to their fair value. The related write-downs are included in earnings as realized losses. In estimating other-than-temporary impairment losses, management considers (1) the length of time and the extent to which the fair value has been less than amortized cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent and ability of the Company to retain its investment for a period of time sufficient to allow for any anticipated recovery in fair value. Investments in non-marketable equity securities such as Federal Reserve Bank (“FRB”) stock and Federal Home Loan Bank of Indianapolis (“FHLB”) stock are carried at cost and are classified as restricted securities. Both cash and stock dividends received from these investments are included in dividend income. Impairment testing on these investments is based on applicable accounting guidance and the cost basis is reduced when impairment is deemed to be other-than-temporary. Loans Held for Sale Prior to July 1, 2018, residential mortgage loans originated and intended for sale in the secondary market were carried at the lower of aggregate cost or market value. Aggregate market value was determined based on the quoted prices under a “best efforts” sales agreement with a third party. Effective July 1, 2018, the Company elected to record residential mortgage loans held for sale at fair value in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 825-10. Net unrealized gains and losses are included in mortgage banking income in the accompanying consolidated statements of income. Realized gains on sales of residential mortgage loans are determined using the specific identification method and are included in mortgage banking income. Residential mortgage loans are sold with servicing released. The Bank originates loans to customers under the SBA 7(a) and other programs that generally provide for SBA guarantees of 75% to 90% of each loan. The Bank intends to sell the guaranteed portion of the SBA loans. The guaranteed portion of the SBA loans was classified as loans held for sale at September 30, 2018 and 2017. At September 30, 2018 and 2017, SBA loans held for sale totaling $21.7 million and $24.9 million, respectively, were carried at the lower of aggregate cost or fair value. Realized gains and losses on sales of SBA loans held for sale are determined based on the allocation of participating interests sold and retained and are included in net gain on sales of SBA loans in the accompanying consolidated statements of income. Direct loan origination costs and fees related to SBA loans held for sale are deferred upon origination and are recognized as an adjustment to the gain or loss on the date of sale. SBA loans held for sale are sold on a servicing retained basis. Transfers of Financial Assets The Company accounts for transfers and servicing of financial assets in accordance with FASB ASC 860, Transfers and Servicing . Transfers of financial assets are accounted for as sales only when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free from conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Transfers of a portion of a loan must meet the criteria of a participating interest. If it does not meet the criteria of a participating interest, the transfer must be accounted for as a secured borrowing. In order to meet the criteria for a participating interest, all cash flows from the loan must be divided proportionately, the rights of each loan holder must have the same priority, and the loan holders must have no recourse to the transferor other than standard representations and warranties and no loan holder has the right to pledge or exchange the entire loan. The Company sells financial assets in the normal course of business, the majority of which are related to the SBA-guaranteed portion of loans, residential mortgage loan sales through established programs, and commercial loan sales through participation agreements. In accordance with accounting guidance for asset transfers, the Company considers any ongoing involvement with transferred assets in determining whether the assets can be derecognized from the balance sheet. With the exception of servicing and certain performance-based guarantees, the Company's continuing involvement with financial assets sold is minimal and generally limited to market customary representation and warranty clauses. When the Company sells financial assets, it may retain servicing rights and/or other interests in the financial assets. The gain or loss on sale depends on the previous carrying amount of the transferred financial assets, the servicing right recognized, and the consideration received and any liabilities incurred in exchange for the transferred assets. Upon transfer, any servicing assets and other interests held by the Company are carried at the lower of cost or fair value. Loans and Allowance for Loan Losses Loans Held for Investment Loans are stated at unpaid principal balances, less net deferred loan fees and the allowance for loan losses. Loan origination and commitment fees, as well as certain direct costs of underwriting and closing loans, are deferred and amortized as a yield adjustment to interest income over the lives of the related loans using the interest method. Amortization of deferred loan fees is discontinued when a loan is placed on nonaccrual status. Nonaccrual Loans The recognition of income on a loan is discontinued and previously accrued interest is reversed when interest or principal payments become 90 days past due unless, in the opinion of management, the outstanding interest remains collectible. Past due status is determined based on contractual terms. Generally, by applying the cash receipts method, interest income on nonaccrual loans is subsequently recognized only as received until the loan is returned to accrual status. The cash receipts method is used when the likelihood of further loss on the loan is remote. Otherwise, the Company applies the cost recovery method and applies all payments as a reduction of the unpaid principal balance until the loan qualifies for return to accrual status. Interest income on impaired loans is recognized using the cost recovery method, unless the likelihood of further loss is considered remote. A loan is restored to accrual status when all principal and interest payments are brought current and the borrower has demonstrated the ability to make future payments of principal and interest as scheduled, which generally requires that the borrower demonstrate a period of performance of at least six consecutive months. Loan Charge-Offs For portfolio segments other than consumer loans, the Company’s practice is to charge-off any loan or portion of a loan when the loan is determined by management to be uncollectible due to the borrower’s failure to meet repayment terms, the borrower’s deteriorating or deteriorated financial condition, depreciation of the underlying collateral, the loan’s classification as a loss by regulatory examiners, or for other reasons. A partial charge-off is recorded on a loan when the uncollectibility of a portion of the loan has been confirmed, such as when a loan is discharged in bankruptcy, the collateral is liquidated, a loan is restructured at a reduced principal balance, or other identifiable events that lead management to determine the full principal balance of the loan will not be repaid. A specific reserve is recognized as a component of the allowance for estimated losses on loans individually evaluated for impairment. Partial charge-offs of loans are included in the Company’s historical loss experience used to estimate the general component of the allowance for loan losses as discussed below. Consumer loans not secured by real estate are typically charged off at 90 days past due, or earlier if deemed uncollectible, unless the loans are in the process of collection. Overdrafts are charged off after 45 days past due. Charge-offs are typically recorded on loans secured by real estate when the property is foreclosed upon when the carrying value of the loan exceeds the property’s fair value less the estimated costs to sell. Allowance for Loan Losses The allowance for loan losses reflects management’s judgment of probable incurred loan losses at the balance sheet date. Additions to the allowance for loan losses are made by the provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The Company evaluates the allowance for loan losses on a quarterly basis based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance consists of specific and general components. The specific component relates to loans that are individually evaluated for impairment. A specific reserve is established when the underlying discounted collateral value (or present value of estimated future cash flows) of the impaired loan is lower than the carrying value of that loan. The general component covers loans not considered to be impaired. Such loans are pooled by segment and losses are modeled using annualized historical loss experience adjusted for qualitative factors. The historical loss experience is determined by portfolio segment and is based on the actual loss history experienced by the Company over the most recent 60-month period. Prior to 2017, management used a 36-month historical loss period as the basis for its allowance for loan losses methodology. However, based on the Company’s loss history and changes in the loan portfolio, management determined that a 60-month historical loss history was appropriate and updated its methodology in 2017. This actual loss experience is then adjusted for qualitative factors that are reviewed on a quarterly basis based on the risks present for each portfolio segment. Management considers changes and trends in the following qualitative loss factors: levels of and trends in delinquencies and impaired loans; levels of and trends in charge-offs and recoveries; trends in the volume and term of new loan originations; national and local economic trends and conditions; changes in lending policies, procedures and practices; changes in the experience and ability of lending management and other staff; changes in the quality and depth of the internal loan review process; trends in collateral valuation in the Company’s lending area; and other factors as determined by management. Each qualitative factor is evaluated and a qualitative factor adjustment is applied to the actual historical loss factors in determining the adjusted loss factors used in management’s allowance for loan losses adequacy calculation. Management exercises significant judgment in evaluating the relevant historical loss experience and the qualitative factors. Management also monitors the differences between estimated and actual incurred loan losses for loans considered impaired in order to evaluate the effectiveness of the estimation process and make any changes in the methodology as necessary. The following portfolio segments are considered in the allowance for loan loss analysis: residential real estate, commercial real estate, multi-family residential real estate, construction, land and land development, commercial business and consumer. Residential real estate loans primarily consist of loans to individuals for the purchase or refinance of their primary residence, with a small portion of the segment secured by non-owner-occupied residential investment properties. The risks associated with residential real estate loans are closely correlated to the local housing market and general economic conditions, as repayment of the loans is primarily dependent on the borrower’s or tenant’s personal cash flow and employment status. Commercial real estate loans are comprised of loans secured by various types of collateral including office buildings, warehouses, retail space and mixed use buildings located in the Company’s primary lending area and in other states. Risks related to commercial real estate lending are related to the market value of the property taken as collateral, the underlying cash flows and general economic conditions. Repayment of these loans is generally dependent on the ability of the borrower to attract tenants at lease rates that provide for adequate debt service and can be impacted by general economic conditions, which impact vacancy rates. The Company generally obtains loan guarantees from financially capable parties for commercial real estate loans. Multi-family residential real estate loans primarily consist of loans secured by apartment buildings and other multi-tenant developments generally located in the Company’s primary lending area. Repayment of these loans is primarily dependent on the borrower’s ability to attract tenants and collect rents that provide for adequate debt service. The risks associated with these loans are closely correlated to the local housing market and general economic conditions. Construction loans consist of single-family residential properties, multi-family properties and commercial projects, and include both owner-occupied and speculative investment properties. Risks inherent in construction lending are related to the market value of the property held as collateral, the cost and timing of constructing or improving a property, the borrower’s ability to use funds generated by a project to service a loan until a project is completed, movements in interest rates and the real estate market during the construction phase, and the ability of the borrower to obtain permanent financing. Land and land development loans primarily consist of loans secured by farmland and vacant land held for long-term investment or development. The risks associated with land and land development loans are related to the market value of the property taken as collateral and the underlying cash flows for loans secured by farmland, and general economic conditions. Commercial business loans include lines of credit to businesses, term loans and letters of credit secured by business assets such as equipment, accounts receivable, inventory, or other assets excluding real estate and are generally made to finance capital expenditures or fund operations. Commercial loans contain risks related to the value of the collateral securing the loan and the repayment is primarily dependent upon the financial success and viability of the borrower. As with commercial real estate loans, the Company generally obtains loan guarantees from financially capable parties for commercial business loans. Consumer loans consist primarily of home equity lines of credit and other loans secured by junior liens on the borrower’s personal residence, home improvement loans, automobile and truck loans, boat loans, mobile home loans, loans secured by savings deposits and other personal loans. The risks associated with these loans are related to the local housing market and local economic conditions including the unemployment level. Other than the change from a 36-month historical loss period to a 60-month historical loss period in 2017 discussed above, there were no significant changes to the Company’s accounting policies or methodology used to estimate the allowance for loan losses during the years ended September 30, 2018, 2017, and 2016. Impaired Loans A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent. Values for collateral dependent loans are generally based on appraisals obtained from independent licensed real estate appraisers, with adjustments applied for estimated costs to sell the property, costs to complete unfinished or repair damaged property and other known defects. New appraisals are generally obtained for all significant properties when a loan is identified as impaired. Generally, a property is considered significant if the value of the property is estimated to exceed $250,000. Subsequent appraisals are obtained as needed or if management believes there has been a significant change in the market value of a collateral property securing an impaired loan. In instances where it is not deemed necessary to obtain a new appraisal, management would base its impairment and allowance for loan loss analysis on the original appraisal with adjustments for current conditions based on management’s assessment of market factors and management’s inspection of the property. Troubled Debt Restructurings The modification of a loan is considered to be a troubled debt restructuring (“TDR”) if the debtor is experiencing financial difficulties and the Company grants a concession to the debtor that it would not otherwise consider. By granting the concession, the Company expects to obtain more cash or other value from the debtor, or to increase the probability of receipt, than would be expected by not granting the concession. The concession may include, but is not limited to, reduction of the stated interest rate of the loan, reduction of accrued interest, extension of the maturity date or reduction of the face amount of the debt. A concession will be granted when, as a result of the restructuring, the Company does not expect to collect all amounts due, including interest at the original stated rate. A concession may also be granted if the debtor is not able to access funds elsewhere at a market rate for debt with similar risk characteristics as the restructured debt. The Company’s determination of whether a loan modification is a TDR considers the individual facts and circumstances surrounding each modification. A TDR can involve loans remaining on nonaccrual, moving to nonaccrual or continuing on accrual status, depending on the individual facts and circumstances of the borrower. Generally, a nonaccrual loan that is restructured in a TDR remains on nonaccrual status for a period of at least six months following the restructuring in order to ensure that the borrower performs in accordance with the restructured terms, including consistent and timely payments of at least six consecutive months according to the restructured terms. Real Estate Development and Construction Real estate that is developed and on which buildings are constructed for the purpose of leasing or sale to third parties by the Company is stated at cost, including interest capitalized during the construction period, less accumulated depreciation. The Company uses the straight line method of computing depreciation at rates adequate to amortize the cost of the applicable assets over their estimated useful lives. Maintenance and repairs are expensed as incurred. The cost and related accumulated depreciation of assets sold, or otherwise disposed of, are removed from the related accounts and any gain or loss is included in earnings. Premises and Equipment Premises and equipment are stated at cost, less accumulated depreciation. The Company uses the straight line method of computing depreciation at rates adequate to amortize the cost of the applicable assets over their estimated useful lives. Maintenance and repairs are expensed as incurred. The cost and related accumulated depreciation of assets sold, or otherwise disposed of, are removed from the related accounts and any gain or loss is included in earnings. Other Real Estate Owned Other real estate owned includes formally foreclosed property, property obtained via a deed in lieu of foreclosure and former banking facilities held for sale. At the time of foreclosure, foreclosed real estate is recorded at its fair value less estimated costs to sell, which becomes the property’s new cost basis. Any write-downs based on the property’s fair value at the date of acquisition are charged to the allowance for loan losses. After foreclosure or the decision to classify property as held for sale, valuations are periodically performed by management and property held for sale is carried at the lower of the new cost basis or fair value, less estimated costs to sell. Costs incurred in maintaining other real estate owned and subsequent impairment adjustments to the carrying amount of a property, if any, are included in noninterest expense. Cash Surrender Value of Life Insurance The Bank has purchased life insurance policies on certain directors, officers and key employees to help offset costs associated with the Bank’s compensation and benefit programs. The Bank is the owner and is a joint or sole beneficiary of the policies. 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. Income from the increase in cash surrender value of the policies and income from the recognition of death benefits is reported in noninterest income. Goodwill and Other Intangibles Goodwill recognized in a business combination represents the excess of the fair value of consideration transferred over the fair value of assets acquired and liabilities assumed. Goodwill is evaluated for possible impairment at least annually or more frequently upon the occurrence of an event or change in circumstances that would more likely than not reduce the fair value of the reporting unit below its carrying amount. Such circumstances could include, but are not limited to: (1) a significant adverse change in legal factors or in business climate, (2) unanticipated competition, or (3) an adverse action or assessment by a regulator. Other intangible assets consist of acquired core deposit intangibles. Core deposit intangibles are amortized over the estimated economic lives of the acquired core deposits. The carrying amount of core deposit intangibles and the remaining estimated economic life are evaluated annually or whenever events or circumstances indicate the carrying amount may not be recoverable or the remaining period of amortization requires revision. Derivative Financial Instruments In connection with the origination of residential mortgage loans to be sold in the secondary market, the Company enters into commitments to originate loans whereby the interest rate on the lo

ACQUISITION OF DEARMIN BANCORP AND THE FIRST NATIONAL BANK OF ODON	(2) ACQUISITION OF DEARMIN BANCORP AND THE FIRST NATIONAL BANK OF ODON On February 9, 2018, the Company acquired Dearmin Bancorp, Inc. (“Dearmin”) and its majority owned subsidiary, The First National Bank of Odon (“FNBO”), a full service community bank located in Odon, Indiana. The acquisition expanded the Company’s presence into Daviess County, Indiana. The Company expects to benefit from growth in this market area as well as from expansion of the banking services provided to the existing customers of FNBO. Cost savings are also expected for the combined bank through economies of scale, efficiencies and the consolidation of business operations. Pursuant to the terms of the merger agreement, FNBO stockholders received $265.00 in cash for each share of FNBO common stock for total cash consideration of $10.6 million. Under the acquisition method of accounting, the purchase price is assigned to the assets acquired and liabilities assumed based on their estimated fair values, net of applicable income tax effects. In accounting for the acquisition, the excess of cost over the fair value of the acquired net assets of $1.9 million has been recorded as goodwill. Transaction and integration costs related to the acquisition totaling $1.3 million and $166,000 were expensed as incurred during the years ended September 30, 2018 and 2017, respectively. During the quarter ended September 30, 2018, management finalized its valuation of certain assets acquired and liabilities assumed in the merger with FNBO, resulting in adjustments to goodwill, core deposit intangible, other assets and net deferred tax liabilities from amounts previously reported. As a result of these adjustments, goodwill and other assets increased $337,000 and $231,000, respectively, while core deposit intangible and net deferred tax liabilities decreased $596,000 and $28,000, respectively, from the amounts previously reported. Following is a condensed balance sheet providing the estimated fair values of the assets acquired and the liabilities assumed as of the date of acquisition: (In thousands) Cash and due from banks $ 1,310 Interest-bearing deposits with banks 15,957 Interest-bearing time deposits with banks 3,817 Investment securities 39,978 Loans, net 34,467 Premises and equipment 1,125 Goodwill arising in the acquisition 1,912 Core deposit intangible 1,487 Other assets 2,890 Total assets acquired 102,943 Deposit accounts 91,765 Net deferred tax liabilities 205 Other liabilities 373 Total liabilities assumed 92,343 Total consideration $ 10,600 In accounting for the acquisition, $1.5 million was assigned to a core deposit intangible which is amortized over a weighted-average estimated economic life of 9.1 years. It is not anticipated that the core deposit intangible will have a significant residual value. No amount of the goodwill or core deposit intangible arising in the acquisition is deductible for income tax purposes. FASB ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality , applies to a loan with evidence of deterioration of credit quality since origination, acquired by completion of a transfer for which it is probable, at acquisition, that the investor will be unable to collect all contractually required payments receivable. On the acquisition date, no loans were identified with evidence of deterioration of credit quality since origination. Loans acquired not subject to ASC 310-30 included non-impaired loans with a fair value of $34.5 million and gross contractual amounts receivable of $41.5 million at the date of acquisition. The following table presents unaudited pro forma information for the years ended September 30, 2018, 2017 and 2016 assuming that the acquisition was consummated on October 1, 2015: (In thousands, except per share data) 2018 2017 2016 Net interest income $ 36,777 $ 32,309 $ 28,062 Net income $ 13,149 $ 10,142 $ 7,472 Net income attributable to First Savings Financial Group, Inc. $ 11,715 $ 10,142 $ 7,472 Net income available to common shareholders $ 11,715 $ 10,142 $ 7,472 Basic earnings per share $ 5.19 $ 4.57 $ 3.40 Diluted earnings per share $ 4.94 $ 4.32 $ 3.24 In addition to combining the historical results of operations, the pro forma calculations consider the purchase accounting adjustments and nonrecurring charges directly related to the acquisition and the related tax effects. The pro forma information for the years ended September 30, 2018 and 2017 was adjusted to exclude $1.3 million and $166,000 of acquisition-related costs incurred during the years and the pro forma information for the year ended September 30, 2016 was adjusted to include those costs. The pro forma calculations do not include any anticipated cost savings as a result of the acquisition. The pro forma information is presented for informational purposes only and is not necessarily indicative of the actual results of operations that would have occurred had the FNBO acquisition actually been consummated on October 1, 2015, or results that may occur in the future.

Investments, Debt and Equity Securities [Abstract]
INVESTMENT SECURITIES	(4) INVESTMENT SECURITIES Investment securities have been classified according to management’s intent. Trading Account Securities Prior to June 30, 2018, the Company invested in small and medium lot, investment grade municipal bonds through a managed brokerage account. The brokerage account was managed by an investment advisory firm registered with the U.S. Securities and Exchange Commission. Trading account securities recorded at fair value totaled $7.2 million at September 30, 2017. The trading account portfolio was liquidated in June 2018. The following is a summary of the reported net gains on trading account securities for the years ended September 30, 2018, 2017 and 2016: (In thousands) 2018 2017 2016 Net realized gain on sales $ 43 $ 229 $ 795 Net unrealized loss on securities held as of the balance sheet date - (29 ) (47 ) Net gain on trading account securities $ 43 $ 200 $ 748 Securities Available for Sale and Held to Maturity The amortized cost of securities available for sale and held to maturity and their approximate fair values are as follows: (In thousands) Amortized Cost Gross Unrealized Gain Gross Unrealized Losses Fair Value September 30, 2018: Securities available for sale: Agency mortgage-backed $ 31,686 $ 90 $ 646 $ 31,130 Agency CMO 10,754 - 313 10,441 Privately-issued CMO 1,434 148 3 1,579 Privately-issued ABS 1,538 346 - 1,884 SBA certificates 1,305 53 7 1,351 Municipal bonds 137,144 2,189 1,345 137,988 Total securities available for sale $ 183,861 $ 2,826 $ 2,314 $ 184,373 Securities held to maturity: Agency mortgage-backed $ 134 $ 8 $ - $ 142 Municipal bonds 2,473 281 - 2,754 Total securities held to maturity $ 2,607 $ 289 $ - $ 2,896 (In thousands) Amortized Cost Gross Unrealized Gain Gross Unrealized Losses Fair Value September 30, 2017: Securities available for sale: Agency mortgage-backed $ 36,439 $ 382 $ 85 $ 36,736 Agency CMO 14,605 37 66 14,576 Privately-issued CMO 1,825 204 28 2,001 Privately-issued ABS 2,691 757 - 3,448 SBA certificates 913 - 1 912 Municipal bonds 115,193 5,409 176 120,426 Total securities available for sale $ 171,666 $ 6,789 $ 356 $ 178,099 Securities held to maturity: Agency mortgage-backed $ 179 $ 16 $ - $ 195 Municipal bonds 2,699 412 - 3,111 Total securities held to maturity $ 2,878 $ 428 $ - $ 3,306 The amortized cost and fair value of available for sale and held to maturity debt securities as of September 30, 2018 by contractual maturity are shown below.

Management evaluates securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. Consideration is given to (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. The total available for sale debt securities in loss positions at September 30, 2018, which consisted of U.S. government agency mortgaged-backed, agency CMOs, privately-issued CMOs, SBA certificates, and municipal bonds, had depreciated approximately 2.64% from the Company’s amortized cost basis and are fixed and variable rate securities with a weighted-average yield of 2.76% and a weighted-average coupon rate of 3.11% at September 30, 2018. All of the agency and municipal securities are issued by U.S. government-sponsored enterprises and municipal governments, and are generally secured by first mortgage loans and municipal project revenues. The Company evaluates the existence of a potential credit loss component related to the decline in fair value of the privately-issued CMO and ABS portfolios each quarter using an independent third party analysis. At September 30, 2018, the Company held 14 privately-issued CMO and ABS securities acquired in a 2009 bank acquisition with an aggregate carrying value of $1.3 million and fair value of $1.6 million that have been downgraded to a substandard regulatory classification due to a downgrade of the security’s credit quality rating by various rating agencies. At September 30, 2018, one privately-issued CMO in a loss position had depreciated approximately 7.50% from the Company’s carrying value and includes securities collateralized by residential mortgage loans and residential home equity lines of credit. This security had a fair value of $37,000 and an unrealized loss of $3,000 at September 30, 2018 and was rated below investment grade by a nationally recognized statistical rating organization (“NRSRO”). Based on the independent third party analysis of the expected cash flows, management has determined that the decline in value for this security is temporary and, as a result, no other-than-temporary impairment is required to be recognized on the remaining privately-issued CMO and ABS portfolios. While the Company does not anticipate additional credit-related impairment losses at September 30, 2018, additional deterioration in market and economic conditions may have an adverse impact on the credit quality in the future and therefore, require additional credit-related impairment charges. During the fiscal year ended September 30, 2018, the Company recognized an other-than-temporary write-down charge to earnings of $95,000 representing the total amortized cost of a privately-issued CMO. The security was determined to be other-than-temporarily impaired and the Company does not anticipate recovering its investment in the security. The unrealized losses on U.S. government agency mortgage-backed securities and CMOs, SBA certificates and municipal bonds relate principally to current interest rates for similar types of securities. In analyzing an issuer’s financial condition, management considers whether the securities are issued by the federal government, its agencies, or other governments, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuer’s financial condition. As management has the ability to hold debt securities to maturity, or for the foreseeable future if classified as available for sale, no declines are deemed to be other-than-temporary. The following is a summary of the reported gross gains and losses on sales of available for sale securities for the years ended September 30, 2018, 2017 and 2016: (In thousands) 2018 2017 2016 Gross realized gains on sales $ 119 $ 96 $ - Gross realized losses on sales (20 ) (66 ) - Net realized gain on sales of available for sale securities $ 99 $ 30 $ - Certain available for sale debt securities were pledged under repurchase agreements and to secure FHLB borrowings at September 30, 2018 and 2017, and may be pledged to secure federal funds borrowings (see Notes 12, 13 and 14). At September 30, 2018 and 2017, there were no holdings of securities of any one issuer, other than the U.S government and its agencies, with an aggregate book value greater than 10% of the Company s consolidated stockholders’ equity.

The Company classifies loans based on credit risk at least quarterly. The Company uses the following regulatory 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. Loss: Loans classified as loss are considered uncollectible and of such little value that their continuance on the Company’s books as an asset is not warranted. Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be pass rated loans.

For the TDRs listed above, the terms of modification included temporary interest-only payment periods, reduction of the stated interest rate, extension of the maturity date, deferral of the contractual principal and interest payments, and the renewal of matured loans where the debtor was unable to access funds elsewhere at a market interest rate for debt with similar risk characteristics. There were no principal charge-offs recorded as a result of TDRs during the years ended September 30, 2018, 2017 and 2016. Provisions for loan losses related to TDRs totaled $5,000 for the year ended September 30, 2018. There were no provisions for loan losses related to TDRs for the years ended September 30, 2017 and 2016. In the event that a TDR subsequently defaults, the Company evaluates the restructuring for possible impairment. As a result, the related allowance for loan losses may be increased or charge-offs may be taken to reduce the carrying amount of the loan. During the years ended September 30, 2018, 2017, and 2016, the Company did not have any TDRs that were modified within the previous twelve months for which there was a payment default (defined as more than 90 days past due or in the process of foreclosure). Loan Servicing Rights The Company originates loans to commercial customers under the SBA 7(a) and other programs, and sells the guaranteed portion of the SBA loans with servicing retained. Loan servicing rights on originated SBA loans that have been sold are initially recorded at fair value. Capitalized servicing rights are then amortized in proportion to and over the period of estimated net servicing income. Impairment of servicing rights is assessed using the present value of estimated future cash flows. The aggregate fair value of loan servicing rights at September 30, 2018 and 2017 approximated its carrying value. A valuation model employed by an independent third party calculates the present value of future cash flows and is used to estimate fair value at the date of sale and on a quarterly basis for impairment analysis purposes. Management periodically compares the valuation model inputs and results to published industry data in order to validate the model results and assumptions. Key assumptions used to estimate the fair value of the loan servicing rights at September 30, 2018 and 2017 were as follows: Assumption Range of Assumption (Weighted Average) 2018 2017 Discount rate 10.84% to 23.22% (14.63%) 9.12% to 13.90% (11.66%) Prepayment rate 4.32% to 14.43% (10.08%) 2.94% to 8.87% (6.63%) For purposes of impairment, risk characteristics such as interest rate, loan type, term and investor type are used to stratify the loan servicing rights. Impairment is recognized through a valuation allowance to the extent that fair value is less than the carrying amount. Changes in the valuation allowance are reported in net gain on sales of loans in the consolidated statements of income. The unpaid principal balance of SBA loans serviced for others was $120.6 million and $61.2 million at September 30, 2018 and 2017, respectively. An analysis of loan servicing fees on SBA loans for the years ended September 30, 2018, 2017 and 2016 is as follows: (In thousands) 2018 2017 2016 Late fees and ancillary fees earned $ 17 $ 47 $ 37 Net servicing income (costs) 863 (9 ) (59 ) SBA net servicing fees (costs) $ 880 $ 38 $ (22 ) Contractually specified late fees and ancillary fees earned on SBA loans are included in interest income on loans in the consolidated statements of income. Net servicing income (contractually specified servicing fees offset by direct servicing expenses) related to SBA loans are included in other noninterest income in the consolidated statements of income.

Expected volatilities are based on historical volatility of the Company’s stock. The expected term of options granted represents the period of time that options are expected to be outstanding. The risk free rate for the expected life of the options is based on the U.S. Treasury yield curve in effect at the grant date. The fair value of options granted during the years ended September 30, 2018 and 2017 was determined using the following assumptions: Expected dividend yield 1.75 % Risk-free interest rate 2.13 % Expected volatility 14.6 % Expected life of options 7.5 years Weighted average fair value at grant date $ 6.13 A summary of stock option activity as of September 30, 2018, and changes during the year then ended is presented below.

Among other things, the Tax Act reduces the Company’s corporate federal tax rate from 34% to 21% $ for the year ended September 30, 2018 . At March 31, 2018, the Company early adopted ASU 2018-02 and reclassified out of retained earnings and into accumulated other comprehensive income approximately $ 619 Tax laws enacted in 2013 and 2014 decrease the Indiana financial institutions tax rate beginning in 2014 and ending in 2023. Deferred taxes have been adjusted to reflect the newly enacted rates and the period in which temporary differences are expected to reverse. In assessing the ability of the Company to realize the benefit of the deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, availability of operating loss carrybacks, projected future taxable income, and tax planning strategies in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods which deferred tax assets are deductible, management believes it is more likely than not the Company will generate sufficient taxable income to realize the benefits of these deductible differences at September 30, 2018, except for a valuation allowance of $1.3 million on the net deferred tax asset related to losses on a historic tax credit investment totaling $5.8 million. In assessing the need for a valuation allowance for the deferred tax assets for the historic tax credit investment, the Company considered all positive and negative evidence in assessing whether the weight of available evidence supports the recognition of some or all of the deferred tax assets related to the investment. Because of the tax nature of the loss to be recognized when the investment is ultimately sold (which for tax purposes will give rise to a capital loss for the historic tax credit investment), the Company may not be able to generate capital gains in the future to be able to utilize the capital losses from the investment. Therefore, the Company’s assessment of the deferred tax asset warrants the need for a valuation allowance. At September 30, 2018 and 2017, the Company had a federal historic tax credit of $0 and $171,000, respectively, available to reduce federal income taxes in subsequent years. At September 30, 2018 and 2017, the Company had no liability for unrecognized income tax benefits and does not anticipate any increase in the liability for unrecognized tax benefits during the next twelve months. The Company believes that its income tax positions would be sustained upon examination and does not anticipate any adjustments that would result in a material change to its financial position or results of operations. The Company files consolidated U.S. federal and Indiana state income tax returns. Returns filed in these jurisdictions for tax years ending on or after September 30, 2014 are subject to examination by the relevant taxing authorities. Each entity included in the consolidated federal and state income tax returns filed by the Company are charged or given credit for the applicable tax as though separate returns were filed. Retained earnings of the Bank at September 30, 2018 and 2017 include approximately $4.6 million for which no deferred federal income tax liability has been recognized. This amount represents an allocation of income to bad debt deductions as of September 30, 1988 for tax purposes only. Reduction of such allocated amounts for purposes other than tax bad debt losses, including redemption of bank stock, excess dividends or loss of “bank” status, would create income for tax purposes only, subject to the then-current corporate income tax rate. The unrecorded deferred income tax liability on these amounts was approximately $957,000 and $1.5 million at September 30, 2018 and 2017, respectively.

Financial Instruments Off Balance Sheet Risks [Abstract]
FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK	(21) FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK The Bank is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the balance sheet. The Bank’s exposure to credit loss in the event of nonperformance by the other party to the financial instruments for commitments to extend credit and standby letters of credit is represented by the contractual notional amount of those instruments. The Bank uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Bank evaluates each customer’s creditworthiness on a case-by-case basis. The amount and type of collateral obtained, if deemed necessary by the Bank upon extension of credit, varies and is based on management’s credit evaluation of the counterparty. Commitments under outstanding standby letters of credit totaled $5.4 million and $5.7 million at September 30, 2018 and 2017, respectively. Standby letters of credit are conditional lending commitments issued by the Bank to guarantee the performance of a customer to a third party. Standby letters of credit generally have fixed expiration dates or other termination clauses and may require payment of a fee. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Bank’s policy for obtaining collateral, and the nature of such collateral, is essentially the same as that involved in making commitments to extend credit. The Bank has not been obligated to perform on any financial guarantees and has incurred no losses on its commitments in 2018 or 2017. The following is a summary of the commitments to extend credit at September 30, 2018 and 2017. Interest rate lock commitments that meet the definition of a derivative are excluded from these totals. (In thousands) 2018 2017 Loan commitments: Fixed rate $ 14,578 $ 17,069 Adjustable rate 22,811 29,933 Guarantees of third-party revolving credit 157 153 Undisbursed portion of home equity lines of credit 30,629 28,422 Undisbursed portion of commercial and personal lines of credit 35,637 23,066 Undisbursed portion of construction loans in process 22,429 25,483 Total commitments to extend credit $ 126,241 $ 124,126

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	(22) DERIVATIVE FINANCIAL INSTRUMENTS The Company enters into commitments to originate loans whereby the interest rate on the loan is determined prior to funding (i.e., rate lock commitment). The Company also enters into forward mortgage loan commitments to sell to various investors to protect itself against exposure to various factors and to reduce sensitivity to interest rate movements. Both the interest rate lock commitments and the related forward mortgage loan sales contracts are considered derivatives and are recorded on the balance sheet at fair value in accordance with FASB ASC 815, Derivatives and Hedging , with changes in fair value recorded in mortgage banking income in the accompanying consolidated statements of income. All such derivatives are considered stand-alone derivatives and have not been formally designated as hedges by management. Certain financial instruments, including derivatives, may be eligible for offset in the balance sheet when the “right of setoff” exists or when the instruments are subject to an enforceable master netting agreement, which includes the right of the non-defaulting party or non-affected party to offset recognized amounts, including collateral posted with the counterparty, to determine a net receivable or net payable upon early termination of the agreement. Certain of the Company’s derivative instruments are subject to master netting agreements. However, the Company has not elected to offset such financial instruments in the consolidated balance sheets. The table below provides information on the Company’s derivative financial instruments as of September 30, 2018. The Company had no derivative financial instruments outstanding at September 30, 2017.

FAIR VALUE MEASUREMENTS

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	(23) FAIR VALUE MEASUREMENTS FASB ASC Topic 820 , Fair Value Measurements, provides the framework for measuring fair value. That framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy under FASB ASC Topic 820 are described as follows: Level 1: Inputs to the valuation methodology are quoted prices, unadjusted, for identical assets or liabilities in active markets. A quoted market price in an active market provides the most reliable evidence of fair value and shall be used to measure fair value whenever available. Level 2: Inputs to the valuation methodology include quoted market prices for similar assets or liabilities in active markets; quoted market prices for identical or similar assets or liabilities in markets that are not active; or inputs that are derived principally from or can be corroborated by observable market data by correlation or other means. Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement. Level 3 assets and liabilities include financial instruments whose value is determined using discounted cash flow methodologies, as well as instruments for which the determination of fair value requires significant management judgment or estimation. 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. These valuation methodologies were applied to all of the Company’s financial assets carried at fair value or the lower of cost or fair value. The table below presents the balances of financial assets measured at fair value on a recurring and nonrecurring basis as of September 30, 2018. The Company had no liabilities measured at fair value as of September 30, 2018.

If quoted market prices are not available, fair value is based on internally-developed models or obtained from third parties that primarily use, as inputs, observable market-based parameters or a matrix pricing model that employs the Bond Market Association’s standard calculations for cash flow and price/yield analysis and observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value, or the lower of cost or fair value. These adjustments may include unobservable parameters. Any such valuation adjustments have been applied consistently over time. The Company’s valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Trading Account Securities and Securities Available for Sale. Securities classified as trading and available for sale are reported at fair value on a recurring basis. These securities are classified as Level 1 of the valuation hierarchy where quoted market prices from reputable third-party brokers are available in an active market. If quoted market prices are not available, the Company obtains fair value measurements from an independent pricing service. These securities are reported using Level 2 inputs and the fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, U.S. government and agency yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and the security’s terms and conditions, among other factors. For securities where quoted market prices, market prices of similar securities or prices from an independent third party pricing service are not available, fair values are calculated using discounted cash flows or other market indicators and are classified within Level 3 of the fair value hierarchy. Changes in fair value of trading account securities are reported in noninterest income. Changes in fair value of securities available for sale are recorded in other comprehensive income, net of income tax effect. Residential Mortgage Loans Held for Sale . Prior to June 30, 2018, residential mortgage loans held for sale were carried at the lower of cost or market value. Effective July 1, 2018, the Company elected to record substantially all of its residential mortgage loans held for sale at fair value in accordance with FASB ASC 825-10. The fair value of residential mortgage loans held for sale is based on specific prices of the underlying contracts for sale to investors or current secondary market prices for loans with similar characteristics, and is classified as level 2 in the fair value hierarchy. SBA Loans Held for Sale . SBA loans held for sale are carried at the lower of cost or market value. The fair value of SBA loans held for sale is based on specific prices of the underlying contracts for sale to investors or current secondary market prices for loans with similar characteristics, and is classified as level 2 in the fair value hierarchy. Derivative Financial Instruments . Derivative financial instruments consist of mortgage banking interest rate lock commitments and forward mortgage loan sale commitments. The fair value of forward mortgage loan sale commitments is obtained from an independent third party and is based on the gain or loss that would occur if the Company were to pair-off the sales transaction with the investor. The fair value of forward mortgage loan sale commitments is classified as Level 2 in the fair value hierarchy. The fair value of interest rate lock commitments is also obtained from an independent third party and is based on investor prices for the underlying loans or current secondary market prices for loans with similar characteristics, less estimated costs to originate the loans and adjusted for the anticipated funding probability (pull-through rate). The fair value of interest rate lock commitments is classified as Level 3 in the fair value hierarchy. The table below presents a reconciliation of derivative assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the years ended September 30, 2018, 2017 and 2016: (In thousands) 2018 2017 2016 Beginning balance $ - $ - $ - Unrealized gains recognized in earnings 380 - - Net settlements - - - Ending balance $ 380 $ - $ - The realized and unrealized gains recognized in earnings in the table above are included in mortgage banking income on the accompanying consolidated statements of income. Gains recognized in earnings for the year ended September 30, 2018 attributable to Level 3 assets held at the balance sheet date were $380,000. The table below presents information about significant unobservable inputs (Level 3) used in the valuation of assets measured at fair value on a recurring basis as of September 30, 2018. No assets were measured at fair value on a recurring basis using significant unobservable inputs (Level 3) as of September 30, 2017. Financial Instrument Significant Unobservable Inputs Range of Inputs Interest rate lock commitments Pull-through rate 72% - 95% Direct costs to close 1% - 3% Impaired Loans . Impaired loans are reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly. The fair value of impaired loans is classified as Level 3 in the fair value hierarchy. Impaired loans are measured at the present value of estimated future cash flows using the loan's effective interest rate or the fair value of the collateral if the loan is a collateral-dependent loan. At September 30, 2018 and 2017, all impaired loans were considered to be collateral-dependent for the purpose of determining fair value. Collateral may be real estate and/or business assets, including equipment, inventory and/or accounts receivable, and its fair value is generally determined based on real estate appraisals or other independent evaluations by qualified professionals. The appraisals are then discounted to reflect management’s estimate of the fair value of the collateral given the current market conditions and the condition of the collateral. At September 30, 2018 and 2017, the significant unobservable inputs used in the fair value measurement of impaired loans included a discount from appraised value ranging from 0.0% to 15.0% and estimated costs to sell the collateral ranging from 0.0% to 12.0%. Provisions for loan losses recognized for impaired loans for the years ended September 30, 2018, 2017 and 2016 is as follows: (In thousands) 2018 2017 2016 Provision for loan losses recognized $ 573 $ 182 $ 43 Loan Servicing Rights . Loan servicing rights represent the value associated with servicing SBA loans that have been sold. The fair value of loan servicing rights is determined on a quarterly basis by an independent third party valuation model using market-based discount rate and prepayment assumptions, and is classified as Level 3 in the fair value hierarchy. At September 30, 2018, the significant unobservable inputs used in the fair value measurement of loan servicing rights included discount rates ranging from 10.84% to 23.22% with a weighted average of 14.63% and prepayment speed assumptions ranging from 4.32% to 14.43% with a weighted average rate of 10.08%. At September 30, 2017, the significant unobservable inputs used in the fair value measurement of loan servicing rights included discount rates ranging from 9.12% to 13.90% with a weighted average of 11.66% and prepayment speed assumptions ranging from 2.94% to 8.87% with a weighted average rate of 6.63%. Impairment of the loan servicing rights is recognized on a quarterly basis through a valuation allowance to the extent that fair value is less than the carrying amount. Impairment charges to write down loan servicing rights to fair value for the years ended September 30, 2018, 2017 and 2016 is as follows: (In thousands) 2018 2017 2016 Charges to write down loan servicing rights $ 177 $ - $ - Other Real Estate Owned . Other real estate owned held for sale is reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly. Fair value of other real estate owned is classified as Level 3 in the fair value hierarchy. Other real estate owned is reported at fair value less estimated costs to dispose of the property. The fair values are determined by real estate appraisals which are then discounted to reflect management’s estimate of the fair value of the property given current market conditions and the condition of the collateral. At September 30, 2018, the significant unobservable inputs used in the fair value measurement of other real estate owned included a discount from appraised value (including estimated costs to sell the property) ranging from 15.0% to 100.0% with a weighted average of 48.9%. At September 30, 2017, the significant unobservable inputs used in the fair value measurement of other real estate owned included a discount from appraised value (including estimated costs to sell the property) ranging from 16.1% to 58.8% with a weighted average of 46.6%. Charges to write down real estate owned to fair value for the years ended September 30, 2018, 2017 and 2016 is as follows: (In thousands) 2018 2017 2016 Charges to write down real estate owned $ 63 $ 28 $ 100 Transfers between Categories . There have been no changes in the valuation techniques and related inputs used for assets measured at fair value on a recurring and nonrecurring basis during the years ended September 30, 2018 and 2017. There were no transfers into or out of Level 3 financial assets or liabilities for the years ended September 30, 2018 and 2017. In addition, there were no transfers into or out of Levels 1 and 2 of the fair value hierarchy during the years ended September 30, 2018 and 2017. Financial Instruments Recorded Using Fair Value Option. Under FASB ASC 825-10, the Company may elect to report most financial instruments and certain other items at fair value on an instrument-by-instrument basis, with changes in fair value reported in income. The election is made at the acquisition of an eligible financial asset or financial liability, and may not be revoked once made. The Company has elected the fair value option for substantially all of its residential mortgage loans held for sale effective July 1, 2018, including all loans originated by the newly formed wholesale lending division. These loans are intended for sale and the Company believes that the fair value is the best indicator of the resolution of these loans. Interest income is recorded based on the contractual terms of the loans and in accordance with the Company’s policy on loans held for investment. None of these loans were 90 days or more past due, nor were any on nonaccrual status as of September 30, 2018. The table below presents the difference between the aggregate fair value and the aggregate remaining principal balance for residential mortgage loans held for sale for which the fair value option had been elected as of September 30, 2018.

Investments and Interest-Bearing Time Deposits For debt securities and interest-bearing time deposits, the Company obtains fair value measurements from an independent pricing service and the fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, U.S. government and agency yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and the security’s terms and conditions, among other factors. Loans The fair value of loans, excluding loans held for sale, 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 terms. Impaired loans are valued at the lower of their carrying value or fair value, as previously described. The carrying amount of accrued interest receivable approximates its fair value. The fair value of loans held for sale is based on specific prices of the underlying contracts for sale to investors or current secondary market prices for loans with similar characteristics, as previously discussed. FRB and FHLB stock It is not practical to determine the fair value of FRB and FHLB stock due to restrictions placed on transferability. Loan Servicing Rights The fair value of loan serving rights is determined by a valuation model employed by an independent third party using market-based discount rate and prepayment assumptions, as previously described. Derivative Financial Instruments The fair value of derivative financial instruments is obtained from an independent third party. The fair value of forward mortgage loan sale commitments is based on the gain or loss that would occur if the Company were to pair-off the sales transaction with the investor. The fair value of interest rate lock commitments is based on investor prices for the underlying loans or current secondary market prices for loans with similar characteristics, less estimated costs to originate the loans and adjusted for the anticipated funding probability (pull-through rate). Deposits The fair value of demand and savings deposits and other transaction accounts is the amount payable on demand at the balance sheet date. The fair value of fixed-maturity time deposits is estimated by discounting the future cash flows using the rates currently offered for deposits with similar remaining maturities. The carrying amount of accrued interest payable approximates its fair value. Borrowed Funds Borrowed funds include borrowings from the FHLB, repurchase agreements and other borrowings. Fair value for FHLB advances, long-term repurchase agreements and subordinated debt is estimated by discounting the future cash flows at current interest rates for FHLB advances of similar maturities. For short-term repurchase agreements and FHLB line of credit borrowings, the carrying value is a reasonable estimate of fair value.

PREFERRED STOCK	(24) PREFERRED STOCK On August 11, 2011, the Company entered into a Securities Purchase Agreement (“Purchase Agreement”) with the United States Department of the Treasury, pursuant to which the Company issued 17,120 shares of its Senior Non-Cumulative Perpetual Preferred Stock, Series A (“Series A Preferred Stock”), having a liquidation amount per share equal to $1,000, for a total purchase price of $17,120,000. The Purchase Agreement was entered into, and the Series A Preferred Stock was issued, pursuant to the Small Business Lending Fund (“SBLF”) program, a $30 billion fund established under the Small Business Jobs Act of 2010, that encourages lending to small businesses by providing Tier 1 capital to qualified community banks with assets of less than $10 billion. The Series A Preferred Stock could be redeemed at any time at the Company’s option, at a redemption price of one hundred percent (100%) of the liquidation amount plus accrued but unpaid dividends to the date of redemption for the current period, subject to the approval of its federal banking regulator. The Series A Preferred Stock was redeemed by the Company for the full liquidation amount of $17,120,000 on February 11, 2016.

Banking and Thrift [Abstract]
CAPITAL REQUIREMENTS AND RESTRICTION ON DIVIDENDS	(25) CAPITAL REQUIREMENTS AND RESTRICTION ON DIVIDENDS The Company and Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and Bank must meet specific capital guidelines that involve quantitative measures of the Company’s and Bank’s assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The Company’s and Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Company and Bank to maintain minimum amounts and ratios (set forth in the table below) of total, Tier 1 and common equity Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and Tier 1 capital (as defined) to average assets (as defined). The final rules implementing the Basel Committee on Banking Supervision’s capital guidelines for U.S. banks (“Basel III rules”) became effective for the Company and the Bank on January 1, 2015, with full compliance with all of the requirements being phased in over a multi-year schedule through 2019. Under the Basel III rules, the Bank must hold a conservation buffer above the adequately capitalized risk-based capital ratios disclosed in the table below. The capital conservation buffer is being phased in from 0.0% for 2015 to 2.5% by 2019. The capital conservation buffer is 1.875% for 2018 and 1.25% for 2017. Management believes that the Company and Bank met all capital adequacy requirements to which they were subject as of September 30, 2018 and 2017. As of September 30, 2018, the most recent notification from the FRB categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, the Bank must maintain minimum total risk-based, Tier I risk-based, common equity Tier 1 risk-based and Tier I leverage ratios as set forth in the table below. There are no conditions or events since that notification that management believes have changed the Bank’s category. The Company’s and Bank’s actual capital amounts and ratios are also presented in the table. No amount was deducted from capital for interest-rate risk in either year.

Under Indiana law, the Company may pay dividends so long as it is able to pay its debts as they become due in the usual course of business and its assets exceed the sum of its total liabilities, plus the amount that would be needed, if the Company were to be dissolved at the time of the dividend, to satisfy any rights that are preferential to the rights of the persons receiving the dividend. The ability of the Company to pay dividends depends primarily on the ability of the Bank to pay dividends to the Company. The payment of dividends by the Bank is subject to banking regulations and applicable Indiana state law. The amount of dividends that the Bank may pay to the Company in any calendar year without prior approval from banking regulators cannot exceed net income for that year to date plus retained net income (as defined) for the preceding two calendar years. The Bank may not declare or pay a cash dividend or repurchase any of its capital stock if the effect thereof would cause the regulatory capital of the Bank to be reduced below regulatory capital requirements imposed by banking regulators or the FDIC, or below the amount of the liquidation account established upon completion of the conversion. Liquidation Account Upon completion of its conversion from mutual to stock form on October 6, 2008, the Bank established a liquidation account in an amount equal to its retained earnings at March 31, 2008, totaling $29.3 million. The liquidation account is maintained for the benefit of depositors as of the March 31, 2007 eligibility record date (or the June 30, 2008 supplemental eligibility record date) who maintain their deposits in the Bank after conversion. In the event of complete liquidation, and only in such an event, each eligible depositor is entitled to receive a liquidation distribution from the liquidation account in the proportionate amount of the then current adjusted balance for deposits held, before any liquidation distribution may be made with respect to the stockholders. Except for the repurchase of stock and payment of dividends by the Bank, the existence of the liquidation account does not restrict the use or application of retained earnings of the Bank.

Segment Reporting [Abstract]
SEGMENT REPORTING	(31) SEGMENT REPORTING The Company’s operations include two primary segments: core banking and SBA lending. The core banking segment originates residential, commercial and consumer loans and attracts deposits from its customer base. Net interest income from loans and investments funded by deposits and borrowings is the primary revenue for the core banking segment. The SBA lending segment originates loans guaranteed by the SBA, subsequently selling the guaranteed portion to outside investors. Net gains on sales of loans and net interest income are the primary sources of revenue for the SBA lending segment. The core banking segment is comprised primarily of the Bank and First Savings Investments, Inc., while the SBA lending segment’s revenues are comprised primarily of net interest income and gains on the sales of SBA loans generated by Q2 beginning January 1, 2017 and SBA loan related income of the Bank prior to the formation of Q2. The following segment financial information has been derived from the internal financial statements of the Company which are used by management to monitor and manage financial performance. The accounting policies of the two segments are the same as those of the Company. The amounts reflected in the “Other” column in the tables below represent combined balances of the Company and the Captive, and are the primary differences between the sum of the segment amounts and consolidated totals, along with amounts to eliminate transactions between segments.

The Bank, which is a wholly-owned Indiana-chartered commercial bank subsidiary of the Company, provides a variety of banking services to individuals and business customers through 16 locations in southern Indiana. The Bank attracts deposits primarily from the general public and uses those funds, along with other borrowings, primarily to originate residential mortgage, commercial mortgage, construction, commercial business and consumer loans, and to a lesser extent, to invest in mortgage-backed securities and other securities. The Bank has two wholly owned subsidiaries: First Savings Investments, Inc., a Nevada corporation that manages a securities portfolio and Southern Indiana Financial Corporation, which is currently inactive. At September 30, 2016, the Bank had a third wholly owned subsidiary, FFCC, Inc. (“FFCC”), which was an Indiana corporation that participated in commercial real estate development and leasing. In accordance with the Plan of Complete Liquidation adopted by FFCC’s board of directors and approval by the Bank as its sole shareholder on December 21, 2016, FFCC voluntarily dissolved and completely liquidated effective December 31, 2016. As a result of the liquidation, FFCC distributed its net assets to the Bank on December 31, 2016. On April 25, 2017, the Bank formed Q2 Business Capital, LLC (“Q2”), which is an Indiana limited liability company that specializes in the origination and servicing of U.S. Small Business Administration (“SBA”) loans. The Bank owns 51% of Q2 with the option to purchase the minority interest between July 1, 2020 and September 30, 2020. In accordance with Q2’s operating agreement, the Bank was allocated the first $1.7 million of cumulative net income of Q2 with any additional profits and losses allocated 51% to the Bank and 49% to Q2’s minority members. The Captive, which is a wholly-owned insurance subsidiary of the Company, is a Nevada corporation that provides property and casualty insurance to the Company, the Bank and the Bank’s active subsidiaries. In addition, the Captive provides reinsurance to 11 other third-party insurance captives for which insurance may not be currently available or economically feasible in the insurance marketplace.
Basis of Consolidation and Reclassifications	Basis of Consolidation and Reclassifications The consolidated financial statements include the accounts of the Company and its subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America and conform to general practices within the banking industry. Intercompany balances and transactions have been eliminated. Certain prior year amounts have been reclassified to conform to the current year presentation. The reclassifications had no effect on net income or stockholders’ equity.
Statements of Cash Flows	Statements of Cash Flows For purposes of the statements of cash flows, the Company has defined cash and cash equivalents as cash on hand, amounts due from banks (including cash items in process of clearing), interest-bearing deposits with other banks having an original maturity of 90 days or less and money market funds.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses and the valuation of real estate and other assets acquired in connection with foreclosures or in satisfaction of loans. In connection with the determination of the allowances for loan losses and the valuation of other real estate owned, management obtains independent appraisals for significant properties. A substantial portion of the Bank’s loan portfolio consists of single-family residential and commercial real estate loans to customers in the southern Indiana and Louisville, Kentucky metropolitan area. Accordingly, the ultimate collectability of a substantial portion of the Bank’s loan portfolio and the recovery of the carrying amount of other real estate owned are susceptible to changes in local market conditions. While management uses available information to recognize losses on loans and other real estate owned, further reductions in the carrying amounts of loans and other real estate owned may be necessary based on changes in local economic conditions. In addition, regulatory agencies, as an integral part of their examination process, periodically review the estimated losses on loans and other real estate owned. Such agencies may require the Company to recognize additional losses based on their judgments about information available to them at the time of their examination. Because of these factors, it is reasonably possible the estimated losses on loans and other real estate owned may change materially in the near term. However, the amount of the change that is reasonably possible cannot be estimated.
Investment Securities	Investment Securities Trading Account Securities : Securities purchased with the intention of recognizing short-term profits or which are actively bought and sold are classified as trading account securities and reported at fair value. The net realized and unrealized gains and losses on trading account securities are reported in noninterest income. Realized gains and losses on trading account securities are determined using the specific identification method. Securities Available for Sale : Securities available for sale consist primarily of municipal obligations, mortgage-backed securities and collateralized mortgage obligations (“CMOs”), and are stated at fair value. The Company holds municipal bonds issued by municipal governments within the U.S.; mortgage-backed securities and CMOs issued by the Government National Mortgage Association (“GNMA”), a U.S. government agency, and the Federal National Mortgage Association (“FNMA”) and the Federal Home Loan Mortgage Corporation (“FHLMC”), government-sponsored enterprises; debt securities issued by government-sponsored enterprises; and privately-issued CMOs and asset-backed securities (“ABSs”). The Company also holds pass-through asset-backed securities guaranteed by the SBA representing participating interests in pools of long-term debentures issued by state and local development companies certified by the SBA. Mortgage-backed securities represent participating interests in pools of long-term first mortgage loans originated and serviced by issuers of the securities. CMOs and ABSs are complex mortgage-backed securities that restructure the cash flows and risks of the underlying mortgage collateral. Amortization of premiums and accretion of discounts are recognized in interest income using methods approximating the interest method over the period to maturity, adjusted for anticipated prepayments. Unrealized gains and losses, net of tax, on securities available for sale are included in other comprehensive income and the accumulated unrealized holding gains and losses are reported as a separate component of equity until realized. Realized gains and losses on the sale of securities available for sale are determined using the specific identification method and are included in other noninterest income and, when applicable, are reported as a reclassification adjustment, net of tax, in other comprehensive income. Securities Held to Maturity : Debt securities for which the Company has the positive intent and ability to hold to maturity are reported at cost, adjusted for amortization of premiums and accretion of discounts that are recognized in interest income using methods approximating the interest method over the period to maturity, adjusted for anticipated prepayments. The Company classifies certain mortgage-backed securities and municipal obligations as held to maturity. Declines in the fair value of individual available for sale and held to maturity securities below their amortized cost that are other than temporary result in write-downs of the individual securities to their fair value. The related write-downs are included in earnings as realized losses. In estimating other-than-temporary impairment losses, management considers (1) the length of time and the extent to which the fair value has been less than amortized cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent and ability of the Company to retain its investment for a period of time sufficient to allow for any anticipated recovery in fair value. Investments in non-marketable equity securities such as Federal Reserve Bank (“FRB”) stock and Federal Home Loan Bank of Indianapolis (“FHLB”) stock are carried at cost and are classified as restricted securities. Both cash and stock dividends received from these investments are included in dividend income. Impairment testing on these investments is based on applicable accounting guidance and the cost basis is reduced when impairment is deemed to be other-than-temporary.
Loans Held for Sale	Loans Held for Sale Prior to July 1, 2018, residential mortgage loans originated and intended for sale in the secondary market were carried at the lower of aggregate cost or market value. Aggregate market value was determined based on the quoted prices under a “best efforts” sales agreement with a third party. Effective July 1, 2018, the Company elected to record residential mortgage loans held for sale at fair value in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 825-10. Net unrealized gains and losses are included in mortgage banking income in the accompanying consolidated statements of income. Realized gains on sales of residential mortgage loans are determined using the specific identification method and are included in mortgage banking income. Residential mortgage loans are sold with servicing released. The Bank originates loans to customers under the SBA 7(a) and other programs that generally provide for SBA guarantees of 75% to 90% of each loan. The Bank intends to sell the guaranteed portion of the SBA loans. The guaranteed portion of the SBA loans was classified as loans held for sale at September 30, 2018 and 2017. At September 30, 2018 and 2017, SBA loans held for sale totaling $21.7 million and $24.9 million, respectively, were carried at the lower of aggregate cost or fair value. Realized gains and losses on sales of SBA loans held for sale are determined based on the allocation of participating interests sold and retained and are included in net gain on sales of SBA loans in the accompanying consolidated statements of income. Direct loan origination costs and fees related to SBA loans held for sale are deferred upon origination and are recognized as an adjustment to the gain or loss on the date of sale. SBA loans held for sale are sold on a servicing retained basis.
Transfers of Financial Assets	Transfers of Financial Assets The Company accounts for transfers and servicing of financial assets in accordance with FASB ASC 860, Transfers and Servicing . Transfers of financial assets are accounted for as sales only when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free from conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Transfers of a portion of a loan must meet the criteria of a participating interest. If it does not meet the criteria of a participating interest, the transfer must be accounted for as a secured borrowing. In order to meet the criteria for a participating interest, all cash flows from the loan must be divided proportionately, the rights of each loan holder must have the same priority, and the loan holders must have no recourse to the transferor other than standard representations and warranties and no loan holder has the right to pledge or exchange the entire loan. The Company sells financial assets in the normal course of business, the majority of which are related to the SBA-guaranteed portion of loans, residential mortgage loan sales through established programs, and commercial loan sales through participation agreements. In accordance with accounting guidance for asset transfers, the Company considers any ongoing involvement with transferred assets in determining whether the assets can be derecognized from the balance sheet. With the exception of servicing and certain performance-based guarantees, the Company's continuing involvement with financial assets sold is minimal and generally limited to market customary representation and warranty clauses. When the Company sells financial assets, it may retain servicing rights and/or other interests in the financial assets. The gain or loss on sale depends on the previous carrying amount of the transferred financial assets, the servicing right recognized, and the consideration received and any liabilities incurred in exchange for the transferred assets. Upon transfer, any servicing assets and other interests held by the Company are carried at the lower of cost or fair value.
Loans and Allowance for Loan Losses	Loans and Allowance for Loan Losses Loans Held for Investment Loans are stated at unpaid principal balances, less net deferred loan fees and the allowance for loan losses. Loan origination and commitment fees, as well as certain direct costs of underwriting and closing loans, are deferred and amortized as a yield adjustment to interest income over the lives of the related loans using the interest method. Amortization of deferred loan fees is discontinued when a loan is placed on nonaccrual status. Nonaccrual Loans The recognition of income on a loan is discontinued and previously accrued interest is reversed when interest or principal payments become 90 days past due unless, in the opinion of management, the outstanding interest remains collectible. Past due status is determined based on contractual terms. Generally, by applying the cash receipts method, interest income on nonaccrual loans is subsequently recognized only as received until the loan is returned to accrual status. The cash receipts method is used when the likelihood of further loss on the loan is remote. Otherwise, the Company applies the cost recovery method and applies all payments as a reduction of the unpaid principal balance until the loan qualifies for return to accrual status. Interest income on impaired loans is recognized using the cost recovery method, unless the likelihood of further loss is considered remote. A loan is restored to accrual status when all principal and interest payments are brought current and the borrower has demonstrated the ability to make future payments of principal and interest as scheduled, which generally requires that the borrower demonstrate a period of performance of at least six consecutive months. Loan Charge-Offs For portfolio segments other than consumer loans, the Company’s practice is to charge-off any loan or portion of a loan when the loan is determined by management to be uncollectible due to the borrower’s failure to meet repayment terms, the borrower’s deteriorating or deteriorated financial condition, depreciation of the underlying collateral, the loan’s classification as a loss by regulatory examiners, or for other reasons. A partial charge-off is recorded on a loan when the uncollectibility of a portion of the loan has been confirmed, such as when a loan is discharged in bankruptcy, the collateral is liquidated, a loan is restructured at a reduced principal balance, or other identifiable events that lead management to determine the full principal balance of the loan will not be repaid. A specific reserve is recognized as a component of the allowance for estimated losses on loans individually evaluated for impairment. Partial charge-offs of loans are included in the Company’s historical loss experience used to estimate the general component of the allowance for loan losses as discussed below. Consumer loans not secured by real estate are typically charged off at 90 days past due, or earlier if deemed uncollectible, unless the loans are in the process of collection. Overdrafts are charged off after 45 days past due. Charge-offs are typically recorded on loans secured by real estate when the property is foreclosed upon when the carrying value of the loan exceeds the property’s fair value less the estimated costs to sell. Allowance for Loan Losses The allowance for loan losses reflects management’s judgment of probable incurred loan losses at the balance sheet date. Additions to the allowance for loan losses are made by the provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The Company evaluates the allowance for loan losses on a quarterly basis based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance consists of specific and general components. The specific component relates to loans that are individually evaluated for impairment. A specific reserve is established when the underlying discounted collateral value (or present value of estimated future cash flows) of the impaired loan is lower than the carrying value of that loan. The general component covers loans not considered to be impaired. Such loans are pooled by segment and losses are modeled using annualized historical loss experience adjusted for qualitative factors. The historical loss experience is determined by portfolio segment and is based on the actual loss history experienced by the Company over the most recent 60-month period. Prior to 2017, management used a 36-month historical loss period as the basis for its allowance for loan losses methodology. However, based on the Company’s loss history and changes in the loan portfolio, management determined that a 60-month historical loss history was appropriate and updated its methodology in 2017. This actual loss experience is then adjusted for qualitative factors that are reviewed on a quarterly basis based on the risks present for each portfolio segment. Management considers changes and trends in the following qualitative loss factors: levels of and trends in delinquencies and impaired loans; levels of and trends in charge-offs and recoveries; trends in the volume and term of new loan originations; national and local economic trends and conditions; changes in lending policies, procedures and practices; changes in the experience and ability of lending management and other staff; changes in the quality and depth of the internal loan review process; trends in collateral valuation in the Company’s lending area; and other factors as determined by management. Each qualitative factor is evaluated and a qualitative factor adjustment is applied to the actual historical loss factors in determining the adjusted loss factors used in management’s allowance for loan losses adequacy calculation. Management exercises significant judgment in evaluating the relevant historical loss experience and the qualitative factors. Management also monitors the differences between estimated and actual incurred loan losses for loans considered impaired in order to evaluate the effectiveness of the estimation process and make any changes in the methodology as necessary. The following portfolio segments are considered in the allowance for loan loss analysis: residential real estate, commercial real estate, multi-family residential real estate, construction, land and land development, commercial business and consumer. Residential real estate loans primarily consist of loans to individuals for the purchase or refinance of their primary residence, with a small portion of the segment secured by non-owner-occupied residential investment properties. The risks associated with residential real estate loans are closely correlated to the local housing market and general economic conditions, as repayment of the loans is primarily dependent on the borrower’s or tenant’s personal cash flow and employment status. Commercial real estate loans are comprised of loans secured by various types of collateral including office buildings, warehouses, retail space and mixed use buildings located in the Company’s primary lending area and in other states. Risks related to commercial real estate lending are related to the market value of the property taken as collateral, the underlying cash flows and general economic conditions. Repayment of these loans is generally dependent on the ability of the borrower to attract tenants at lease rates that provide for adequate debt service and can be impacted by general economic conditions, which impact vacancy rates. The Company generally obtains loan guarantees from financially capable parties for commercial real estate loans. Multi-family residential real estate loans primarily consist of loans secured by apartment buildings and other multi-tenant developments generally located in the Company’s primary lending area. Repayment of these loans is primarily dependent on the borrower’s ability to attract tenants and collect rents that provide for adequate debt service. The risks associated with these loans are closely correlated to the local housing market and general economic conditions. Construction loans consist of single-family residential properties, multi-family properties and commercial projects, and include both owner-occupied and speculative investment properties. Risks inherent in construction lending are related to the market value of the property held as collateral, the cost and timing of constructing or improving a property, the borrower’s ability to use funds generated by a project to service a loan until a project is completed, movements in interest rates and the real estate market during the construction phase, and the ability of the borrower to obtain permanent financing. Land and land development loans primarily consist of loans secured by farmland and vacant land held for long-term investment or development. The risks associated with land and land development loans are related to the market value of the property taken as collateral and the underlying cash flows for loans secured by farmland, and general economic conditions. Commercial business loans include lines of credit to businesses, term loans and letters of credit secured by business assets such as equipment, accounts receivable, inventory, or other assets excluding real estate and are generally made to finance capital expenditures or fund operations. Commercial loans contain risks related to the value of the collateral securing the loan and the repayment is primarily dependent upon the financial success and viability of the borrower. As with commercial real estate loans, the Company generally obtains loan guarantees from financially capable parties for commercial business loans. Consumer loans consist primarily of home equity lines of credit and other loans secured by junior liens on the borrower’s personal residence, home improvement loans, automobile and truck loans, boat loans, mobile home loans, loans secured by savings deposits and other personal loans. The risks associated with these loans are related to the local housing market and local economic conditions including the unemployment level. Other than the change from a 36-month historical loss period to a 60-month historical loss period in 2017 discussed above, there were no significant changes to the Company’s accounting policies or methodology used to estimate the allowance for loan losses during the years ended September 30, 2018, 2017, and 2016. Impaired Loans A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent. Values for collateral dependent loans are generally based on appraisals obtained from independent licensed real estate appraisers, with adjustments applied for estimated costs to sell the property, costs to complete unfinished or repair damaged property and other known defects. New appraisals are generally obtained for all significant properties when a loan is identified as impaired. Generally, a property is considered significant if the value of the property is estimated to exceed $250,000. Subsequent appraisals are obtained as needed or if management believes there has been a significant change in the market value of a collateral property securing an impaired loan. In instances where it is not deemed necessary to obtain a new appraisal, management would base its impairment and allowance for loan loss analysis on the original appraisal with adjustments for current conditions based on management’s assessment of market factors and management’s inspection of the property. Troubled Debt Restructurings The modification of a loan is considered to be a troubled debt restructuring (“TDR”) if the debtor is experiencing financial difficulties and the Company grants a concession to the debtor that it would not otherwise consider. By granting the concession, the Company expects to obtain more cash or other value from the debtor, or to increase the probability of receipt, than would be expected by not granting the concession. The concession may include, but is not limited to, reduction of the stated interest rate of the loan, reduction of accrued interest, extension of the maturity date or reduction of the face amount of the debt. A concession will be granted when, as a result of the restructuring, the Company does not expect to collect all amounts due, including interest at the original stated rate. A concession may also be granted if the debtor is not able to access funds elsewhere at a market rate for debt with similar risk characteristics as the restructured debt. The Company’s determination of whether a loan modification is a TDR considers the individual facts and circumstances surrounding each modification. A TDR can involve loans remaining on nonaccrual, moving to nonaccrual or continuing on accrual status, depending on the individual facts and circumstances of the borrower. Generally, a nonaccrual loan that is restructured in a TDR remains on nonaccrual status for a period of at least six months following the restructuring in order to ensure that the borrower performs in accordance with the restructured terms, including consistent and timely payments of at least six consecutive months according to the restructured terms.
Real Estate Development and Construction	Real Estate Development and Construction Real estate that is developed and on which buildings are constructed for the purpose of leasing or sale to third parties by the Company is stated at cost, including interest capitalized during the construction period, less accumulated depreciation. The Company uses the straight line method of computing depreciation at rates adequate to amortize the cost of the applicable assets over their estimated useful lives. Maintenance and repairs are expensed as incurred. The cost and related accumulated depreciation of assets sold, or otherwise disposed of, are removed from the related accounts and any gain or loss is included in earnings.
Premises and Equipment	Premises and Equipment Premises and equipment are stated at cost, less accumulated depreciation. The Company uses the straight line method of computing depreciation at rates adequate to amortize the cost of the applicable assets over their estimated useful lives. Maintenance and repairs are expensed as incurred. The cost and related accumulated depreciation of assets sold, or otherwise disposed of, are removed from the related accounts and any gain or loss is included in earnings.
Other Real Estate Owned	Other Real Estate Owned Other real estate owned includes formally foreclosed property, property obtained via a deed in lieu of foreclosure and former banking facilities held for sale. At the time of foreclosure, foreclosed real estate is recorded at its fair value less estimated costs to sell, which becomes the property’s new cost basis. Any write-downs based on the property’s fair value at the date of acquisition are charged to the allowance for loan losses. After foreclosure or the decision to classify property as held for sale, valuations are periodically performed by management and property held for sale is carried at the lower of the new cost basis or fair value, less estimated costs to sell. Costs incurred in maintaining other real estate owned and subsequent impairment adjustments to the carrying amount of a property, if any, are included in noninterest expense.
Cash Surrender Value of Life Insurance	Cash Surrender Value of Life Insurance The Bank has purchased life insurance policies on certain directors, officers and key employees to help offset costs associated with the Bank’s compensation and benefit programs. The Bank is the owner and is a joint or sole beneficiary of the policies. 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. Income from the increase in cash surrender value of the policies and income from the recognition of death benefits is reported in noninterest income.
Goodwill and Other Intangibles	Goodwill and Other Intangibles Goodwill recognized in a business combination represents the excess of the fair value of consideration transferred over the fair value of assets acquired and liabilities assumed. Goodwill is evaluated for possible impairment at least annually or more frequently upon the occurrence of an event or change in circumstances that would more likely than not reduce the fair value of the reporting unit below its carrying amount. Such circumstances could include, but are not limited to: (1) a significant adverse change in legal factors or in business climate, (2) unanticipated competition, or (3) an adverse action or assessment by a regulator. Other intangible assets consist of acquired core deposit intangibles. Core deposit intangibles are amortized over the estimated economic lives of the acquired core deposits. The carrying amount of core deposit intangibles and the remaining estimated economic life are evaluated annually or whenever events or circumstances indicate the carrying amount may not be recoverable or the remaining period of amortization requires revision.
Derivative Financial Instruments	Derivative Financial Instruments In connection with the origination of residential mortgage loans to be sold in the secondary market, the Company enters into commitments to originate loans whereby the interest rate on the loan is determined prior to funding (i.e., rate lock commitment). The period of time between issuance of a loan commitment and closing and sale of the loan generally ranges from 15 to 60 days. The Company also enters into forward mortgage loan commitments to sell to various investors to protect itself against exposure to various factors and to reduce sensitivity to interest rate movements. Both the interest rate lock commitments and the related forward mortgage loan sales contracts are considered derivatives and are recorded on the balance sheet at fair value in accordance with FASB ASC 815, Derivatives and Hedging , with changes in fair value recorded in mortgage banking income in the accompanying consolidated statements of income. All such derivatives are considered stand-alone derivatives and have not been formally designated as hedges by management.
Securities Lending and Financing Arrangements	Securities Lending and Financing Arrangements Securities purchased under agreements to resell (reverse repurchase agreements) and securities sold under agreements to repurchase (repurchase agreements) are treated as collateralized lending and borrowing transactions, respectively, and are carried at the amounts at which the securities were initially acquired or sold.
Benefit Plans	Benefit Plans The Bank provides a contributory defined contribution plan available to all eligible employees. The Company also established a leveraged employee stock ownership plan (“ESOP”) on October 6, 2008 that includes substantially all employees. The Company accounts for the ESOP in accordance with FASB ASC 718-40, Employee Stock Ownership Plans . Dividends declared on allocated shares are recorded as a reduction of retained earnings and paid to the participants’ accounts or used for additional debt service on the ESOP loan. Dividends declared on unallocated shares are not considered dividends for financial reporting purposes and are used for additional debt service on the ESOP loan. As shares are committed to be released for allocation to participants’ accounts, compensation expense is recognized based on the average fair value of the shares and the shares become available for earnings per share calculations.
Stock Based Compensation	Stock Based Compensation The Company has adopted the fair value based method of accounting for stock-based compensation prescribed in FASB ASC 718-20, Compensation – Stock Compensation , for its stock plans.
Income Taxes	Income Taxes When income tax returns are filed, it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while other positions are subject to some degree of uncertainty regarding the merits of the position taken or the amount of the position that would be sustained. The Company recognizes the benefits of a tax position in the consolidated financial statements of the period during which, based on all available evidence, management believes it is more-likely-than-not (more than 50 percent probable) that the tax position would be sustained upon examination. Income tax positions that meet the more-likely-than-not threshold are measured as the largest amount of income tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with the income tax positions claimed on income tax returns that exceeds the amount measured as described above is reflected as a liability for unrecognized income tax benefits in the consolidated balance sheets, along with any associated interest and penalties that would be payable to the taxing authorities, if there were an examination. Interest and penalties associated with unrecognized income tax benefits are classified as additional income taxes in the consolidated statements of income. Income taxes are provided for the tax effects of the transactions reported in the financial statements and consist of taxes currently due plus deferred income taxes. Income tax reporting and financial statement reporting rules differ in many respects. As a result, there will often be a difference between the carrying amount of an asset or liability as presented in the accompanying consolidated balance sheets and the amount that would be recognized as the tax basis of the same asset or liability computed based on the effects of tax positions recognized, as described in the preceding paragraph. These differences are referred to as temporary differences because they are expected to reverse in future years. Deferred income tax assets are recognized for temporary differences where their future reversal will result in future tax benefits. Deferred income tax assets are also recognized for the future tax benefits expected to be realized from net operating loss or tax credit carryforwards. Deferred income tax liabilities are recognized for temporary differences where their future reversal will result in the payment of future income taxes. Deferred income tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred income tax assets will not be realized. Deferred tax assets and liabilities are reflected at income tax rates applicable to the period in which the deferred tax assets or liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes.
Advertising Costs	Advertising Costs Advertising costs are charged to operations when incurred.
Comprehensive Income	Comprehensive Income Comprehensive income consists of reported net income and other comprehensive income. Other comprehensive income, recognized as a separate component of equity, includes the change in unrealized gains and losses on securities available for sale. Amounts reclassified out of unrealized gains or losses on securities available for sale included in accumulated other comprehensive income or loss are included in the net gain on sales of available for sale securities and other than temporary impairment loss on securities line items in the consolidated statements of income.
Loss Contingencies	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.
Recent Accounting Pronouncements	Recent Accounting Pronouncements The following are summaries of recently issued or adopted accounting pronouncements that impact the accounting and reporting practices of the Company: In May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606) . The update provides a five-step revenue recognition model for all revenue arising from contracts with customers and affects all entities that enter into contracts to provide goods or services to their customers (unless the contracts are included in the scope of other standards). The guidance requires an entity to recognize the revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. For public entities, the guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those reporting periods. Management is evaluating the new guidance, but does not expect the adoption of this guidance to have a material impact on the Company’s consolidated financial position or results of operations. 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 guidance addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments. In particular, the guidance revises an entity’s accounting related to (1) the classification and measurement of investments in equity securities and (2) the presentation of certain fair value changes for financial liabilities measured at fair value. The guidance also amends certain disclosure requirements associated with fair value of financial instruments. For public business entities, the guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Entities should apply the amendments by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The adoption of this update is not expected to have a material impact on the Company’s consolidated financial position or results of operations. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) . The guidance supersedes existing guidance on accounting for leases with the main difference being that operating leases are to be recorded in the statement of financial position as right-of-use assets and lease liabilities, initially measured at the present value of the lease payments. For operating leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election not to recognize lease assets and liabilities. For public business entities, the guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application of the guidance is permitted. In transition, entities are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326) . The update replaces the incurred loss methodology for recognizing credit losses under current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. Under the new guidance, an entity will measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. The expected loss model will apply to loans and leases, unfunded lending commitments, held-to-maturity debt securities and other debt instruments measured at amortized cost. The impairment model for available-for-sale debt securities will require the recognition of credit losses through a valuation allowance when fair value is less than amortized cost, regardless of whether the impairment is considered to be other-than-temporary. For the Company, the amendments in the update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted as of fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is currently assessing the impact the guidance will have upon adoption. Management expects to recognize a one-time cumulative-effect adjustment to the allowance for loan losses through retained earnings as of the beginning of the first reporting period in which the new standard is effective; however, the magnitude of the adjustment is unknown. In planning for the implementation of ASU 2016-13, management is currently evaluating software solutions, data requirements and loss methodologies. In March 2017, the FASB issued ASU No. 2017-08, Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20) – Premium Amortization on Purchased Callable Debt Securities . The update shortens the amortization period for certain callable debt securities held at a premium. Specifically, the update requires the premium to be amortized to the earliest call date. The update does not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The amendments in the update are effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity should apply the amendments in this update on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. Additionally, in the period of adoption, an entity should provide disclosures about a change in accounting principle. The adoption of this update is not expected to have a material impact on the Company’s consolidated financial position or results of operations. In August 2018, the FASB issued ASU No. 2018-13, Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement . The update removes, modifies and adds certain disclosure requirements for fair value measurements. Among other changes, entities will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for timing of transfers between levels and the valuation processes for Level 3 fair value measurements, but will be required to disclose the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The amendments in the update are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted upon issuance of the update. The adoption of this update is not expected to have a material impact on the Company’s consolidated financial position or results of operations.
