Presentation of Interim Information
Presentation of Interim Information	1. 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 commercial mortgage, residential mortgage, construction, commercial business and consumer loans, and to a lesser extent, to invest in mortgage-backed securities, municipal bonds and other investment 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. 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. 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 Q2’s cumulative net income with any additional profits and losses allocated 51% to the Bank and 49% to Q2’s minority members. In the opinion of management, the accompanying unaudited consolidated financial statements include all adjustments considered necessary to present fairly the financial position as of June 30, 2019, the results of operations for the three- and nine-month periods ended June 30, 2019 and 2018, and the cash flows for the nine-month periods ended June 30, 2019 and 2018. All of these adjustments are of a normal, recurring nature. Such adjustments are the only adjustments included in the unaudited consolidated financial statements. Interim results are not necessarily indicative of results for a full year. The unaudited consolidated financial statements and notes have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial statements, conform to general practices within the banking industry and are presented as permitted by the instructions to Form 10‑Q. Accordingly, they do not contain certain information included in the Company’s audited consolidated financial statements and related notes for the year ended September 30, 2018 included in the Company’s Annual Report on Form 10‑K. The unaudited consolidated financial statements include the accounts of the Company and its subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform with the current period presentation. The reclassifications had no effect on net income or stockholders’ equity.

Acquisition of Dearmin Bancorp and The First National Bank of Odon
Acquisition of Dearmin Bancorp and The First National Bank of Odon	2. 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 identifiable assets acquired and liabilities assumed based on their 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 was recorded as goodwill. Transaction and integration costs related to the acquisition totaling $1.3 million were expensed as incurred for the nine-month period ended June 30, 2018. No transaction and integration costs were recognized for the three-month period ended June 30, 2018 or the three- and nine-month periods ended June 30, 2019. 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. Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“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.

U.S. agency bonds and notes, agency mortgage-backed securities and agency collateralized mortgage obligations (“CMO”) include treasury notes issued by the U.S. government; securities issued by the Government National Mortgage Association (“GNMA”), a U.S. government agency; and securities issued by the Federal National Mortgage Association (“FNMA”), the Federal Home Loan Mortgage Corporation (“FHLMC”) and the Federal Home Loan Bank (“FHLB”), which are U.S. government sponsored enterprises. The Company holds municipal bonds issued by municipal governments within the U.S. 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. Privately issued CMO and asset-backed securities (“ABS”) are complex securities issued by non-government special purpose entities that are collateralized by residential mortgage loans and residential home equity loans. 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. During May 2018, the Company ceased its trading activity and had no trading account securities at September 30, 2018 or June 30, 2019. As such, there were no gains or losses on trading account securities during the three and nine-month periods ended June 30, 2019. During the three-month period ended June 30, 2018, the Company reported a net loss on trading account securities of $48,000. During the nine-month period ended June 30, 2018, the Company reported a net gain on trading account securities of $43,000.

At June 30, 2019 and September 30, 2018, the Company did not have any securities held to maturity with an unrealized loss. Management evaluates securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market conditions 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 June 30, 2019, which consisted of U.S. government agency mortgage backed securities and CMOs, privately issued CMOs, SBA certificates and municipal bonds, had a fair value as a percentage of amortized cost of 99.81%. 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 June 30, 2019, the Company held thirteen privately-issued CMO and ABS securities, acquired in a 2009 bank merger, with an aggregate amortized cost of $1.1 million and fair value of $1.3 million that have been downgraded to a substandard regulatory classification due to the security’s credit quality rating by various nationally recognized statistical rating organizations (“NRSROs”). At June 30, 2019, one privately-issued CMO was in a loss position and had depreciated approximately 8.23% from the Company’s carrying value and was collateralized by residential mortgage loans. This security had a total fair value of $37,000 and a total unrealized loss of $3,000 at June 30, 2019, and was rated below investment grade by NRSROs. Based on the independent third party analysis of the expected cash flows, management has determined that no other-than-temporary impairment is required to be recognized on the remaining privately issued CMO and ABS portfolios. While the Company had not anticipated additional credit-related impairment losses at June 30, 2019, additional deterioration in market and economic conditions may have an adverse impact on the credit quality in the future, and therefore, require a credit related impairment charge in the future. 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. During the three month period ended June 30, 2019, the Company realized gross gains of $67,000 and gross losses of $123,000 on sales of available for sale securities. During the nine month period ended June 30, 2019, the Company realized gross gains of $68,000 and gross losses of $123,000 on sales of available for sale securities. During the three and nine-month periods ended June 30, 2018, the Company realized gross gains of $119,000 and gross losses of $20,000 on sales of available for sale securities. Certain available for sale debt securities were pledged under repurchase agreements and to secure FHLB borrowings at June 30, 2019 and September 30, 2018, and may be pledged to secure federal funds borrowings.

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 Company’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 Company 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. As of June 30, 2019, and based on the most recent analysis performed, the recorded investment in loans by risk category was as follows: Residential Commercial Land and Land Commercial Real Estate Real Estate Multifamily Construction Development Business Consumer Total (In thousands) Pass $ 198,483 $ 399,743 $ 38,862 $ 23,864 $ 12,197 $ 77,915 $ 42,352 $ 793,416 Special Mention — 490 — — — 398 — 888 Substandard 4,060 8,308 477 — — 2,465 82 15,392 Doubtful 62 — — — — — 2 64 Loss — — — — — — — — Total $ 202,605 $ 408,541 $ 39,339 $ 23,864 $ 12,197 $ 80,778 $ 42,436 $ 809,760 As of September 30, 2018, the recorded investment in loans by risk category was as follows: Residential Commercial Land and Land Commercial Real Estate Real Estate Multifamily Construction Development Business Consumer Total (In thousands) Pass $ 190,647 $ 338,256 $ 28,365 $ 28,347 $ 10,207 $ 66,162 $ 39,246 $ 701,230 Special Mention 19 — — — 290 — — 309 Substandard 5,061 6,749 500 — 27 2,264 67 14,668 Doubtful 74 — — — — — — 74 Loss — — — — — — — — Total $ 195,801 $ 345,005 $ 28,865 $ 28,347 $ 10,524 $ 68,426 $ 39,313 $ 716,281 Troubled Debt Restructurings 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 or maturity 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. Loans modified in a TDR may be retained on accrual status if the borrower has maintained a period of performance in which the borrower’s lending relationship was not greater than ninety days delinquent at the time of restructuring and the Company determines the future collection of principal and interest is reasonably assured. Loans modified in a TDR that are placed on nonaccrual status at the time of restructuring will continue on nonaccrual status until the Company determines the future collection of principal and interest is reasonably assured, which generally requires that the borrower demonstrate a period of performance according to the restructured terms of at least six consecutive months. The following table summarizes the Company’s recorded investment in TDRs at June 30, 2019 and September 30, 2018. There was $56,000 of specific reserve included in the allowance for loan losses related to TDRs at June 30, 2019. There was $5,000 of specific reserve included in the allowance for loan losses related to TDRs at September 30, 2018. Accruing Nonaccrual Total (In thousands) June 30, 2019: Residential real estate $ 1,895 $ 357 $ 2,252 Commercial real estate 6,072 62 6,134 Commercial business 184 — 184 Consumer 75 — 75 Total $ 8,226 $ 419 $ 8,645 September 30, 2018: Residential real estate $ 2,396 $ 21 $ 2,417 Commercial real estate 6,435 65 6,500 Commercial business 231 — 231 Consumer 83 — 83 Total $ 9,145 $ 86 $ 9,231 There were no TDRs that were restructured during the three- and nine-month periods ended June 30, 2019. There were no TDRs that were restructured during the three month period ended June 30, 2018. The following table summarizes information in regard to TDRs that were restructured during the nine-month period ended June 30, 2018: Pre- Post- Modification Modification Number of Principal Principal Loans Balance Balance (Dollars in thousands) Nine Months Ended June 30, 2018: Residential real estate 1 $ 140 $ 120 Commercial real estate 1 1,674 1,674 Commercial business 1 170 170 Consumer 1 3 3 Total 4 $ 1,987 $ 1,967 For the TDRs listed above, the terms of modification included deferral of contractual principal and interest payments, reduction of the stated interest rate and extension of the maturity date where the debtor was unable to access funds elsewhere at a market interest rate for debt with similar risk characteristics. At June 30, 2019 and September 30, 2018, the Company had committed to lend $1,000 to customers with outstanding loans classified as TDRs. There were no principal charge-offs recorded as a result of TDRs during the three- and nine-month periods ended June 30, 2019 and 2018. There was no specific allowance for loan losses related to TDRs modified during the three- and nine-month periods ended June 30, 2019 and 2018. 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 nine-month period ended June 30, 2019, the Company had one TDR with an outstanding balance of $114,000 that was modified within the previous twelve months and for which there was a payment default. During the three month period ended June 30, 2019 and the three- and nine-month periods ended June 30, 2018, the Company did not have any TDRs that were modified within the previous twelve months and for which there was a payment default. 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 rights 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 approximates 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 include the discount rate and prepayment speed assumptions. 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 $151.4 million, $120.6 million and $113.5 million at June 30, 2019, September 30, 2018 and June 30, 2018, respectively. Contractually specified late fees and ancillary fees earned on SBA loans were $11,000 and $27,000 for the three- and nine-month periods ended June 30, 2019, respectively. Contractually specified late fees and ancillary fees earned on SBA loans were $3,000 and $12,000 for the three- and nine-month periods ended June 30, 2018, respectively. Net servicing income (contractually specified servicing fees offset by direct servicing expenses) related to SBA loans was $317,000 and $890,000 for the three- and nine-month periods ended June 30, 2019, respectively. Net servicing income (contractually specified servicing fees offset by direct servicing expenses) related to SBA loans was $240,000 and $581,000 for the three- and nine-month periods ended June 30, 2018, respectively. Net servicing income and costs are included in other noninterest income in the consolidated statements of income. An analysis of SBA loan servicing rights for the three- and nine-month periods ended June 30, 2019 and 2018 is as follows: Three Months Ended Nine Months Ended June 30, June 30, (In thousands) 2019 2018 2019 2018 (In thousands) Balance, beginning of period $ 2,595 $ 2,116 $ 2,405 $ 1,389 Servicing rights resulting from transfers of loans 449 430 892 1,297 Amortization (130) (83) (383) (223) Direct write-offs (142) — (142) — Change in valuation allowance 72 (18) 72 (18) Balance, end of period $ 2,844 $ 2,445 $ 2,844 $ 2,445 Residential mortgage loans originated for sale in the secondary market continue to be sold with servicing released. The valuation allowance related to SBA loan servicing rights at June 30, 2019 and September 30, 2018 was $105,000 and $177,000, respectively.

Fair Value Measurements and Disclosures about Fair Value of Financial Instruments
Fair Value Measurements and Disclosures about Fair Value of Financial Instruments	8. 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 and liabilities carried at fair value or the lower of cost or fair value. The tables below present the balances of financial assets and liabilities measured at fair value on a recurring and nonrecurring basis as of June 30, 2019 and 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 at 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. Other than SBA loans held for sale (see discussion below), 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 nine-month period ended June 30, 2019. Securities Available for Sale. Securities classified as 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 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. At September 30, 2018, the fair value of SBA loans held for sale was obtained from an independent third party pricing firm based on specific prices of the underlying contracts for sale to investors or current secondary market prices for loans with similar characteristics, and was classified as Level 2 in the fair value hierarchy. At June 30, 2019, the fair value of SBA loans held for sale reflects management’s estimate based on the weighted average price of SBA loans sold to investors during the prior quarter and is classified as Level 3 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 three- and nine-months ended June 30, 2019 and 2018: Three Months Ended Nine Months Ended June 30, June 30, (In thousands) 2019 2018 2019 2018 Beginning balance $ 1,705 $ — $ 380 $ — Unrealized gains recognized in earnings, net of settlements 1,587 — 2,912 — Ending balance $ 3,292 $ — $ 3,292 $ — 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 three- and nine-months ended June 30, 2019 attributable to Level 3 assets held at the balance sheet date were $3.3 million. 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 June 30, 2019 and September 30, 2018. Range of Range of Significant Inputs Inputs Financial Instrument Unobservable Inputs June 30, 2019 September 30, 2018 Interest rate lock commitments Pull-through rate 40% - 100% 72% - 95% Direct costs to close 1% 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 June 30, 2019 and September 30, 2018, 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 generally then discounted by management in order to reflect management’s estimate of the fair value of the collateral given the current market conditions and the condition of the collateral. At June 30, 2019 and September 30, 2018, the significant unobservable inputs used in the fair value measurement of impaired loans included discounts from appraised value ranging from 0.0% to 15.0% and estimated costs to sell the collateral ranging from 0.0% to 6.0%. During the three-month periods ended June 30, 2019 and 2018, the Company recognized provisions for loan losses of $171,000 and $331,000, respectively, for impaired loans. During the nine-month periods ended June 30, 2019 and 2018, the Company recognized provisions for loan losses of $717,000 and $349,000, respectively, for impaired loans. 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 June 30, 2019, the significant unobservable inputs used in the fair value measurement of loan servicing rights included discount rates ranging from 6.81% to 16.74% with a weighted average of 10.80% and prepayment speed assumptions ranging from 5.68% to 18.23% with a weighted average rate of 12.30%. 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%. 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. The Company recognized $70,000 of impairment charges on loan servicing rights for the three- and nine-month periods ended June 30, 2019 and 2018. The Company recognized $18,000 of impairment charges on loan servicing rights for the three- and nine-month periods ended June 30, 2018. 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. The 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 generally discounted by management in order to reflect management’s estimate of the fair value of the property given current market conditions and the condition of the property. At June 30, 2019, 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 18.4% with a weighted average of 16.2%. 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%. The Company did not recognize any charges to write down other real estate owned to fair value for the three- and nine-month periods ended June 30, 2019. The Company recognized charges of $4,000 and $63,000 to write-down other real estate owned to fair value for the three- and nine-month periods ended June 30, 2018. Transfers Between Categories. As previously described, management used different valuation methodologies related to SBA loans held for sale at June 30, 2019 and September 30, 2018, resulting in a change in classification from Level 2 to Level 3 for those types of instruments. Other than that change, there were no transfers into or out of Levels 1, 2, or 3 of the fair value hierarchy for the three- and nine-month periods ended June 30, 2019 and 2018. 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 Company’s 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 June 30, 2019 and 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 June 30, 2019 and September 30, 2018.

In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instruments. Accordingly, the aggregate fair value amounts presented do not represent the underlying value of the Company. The carrying amounts and estimated fair values of the Company’s financial instruments are as follows. In accordance with the Company’s adoption of Accounting Standards Update (“ASU”) 2016‑01 effective October 1, 2018, the table below for June 30, 2019 presents the fair values measured using an exit price notion. The fair value of loans at September 30, 2018 was measured using an entry price notion.

Stock Based Compensation Plans
Employee Stock Ownership Plan	9. On October 6, 2008, the Company established a leveraged employee stock ownership plan (“ESOP”) covering substantially all employees. The ESOP trust acquired 203,363 shares of Company common stock at a cost of $10.00 per share financed by a term loan with the Company. The employer loan and the related interest income are not recognized in the consolidated financial statements because the debt is serviced from Company contributions. Dividends payable on allocated shares are charged to retained earnings and are satisfied by the allocation of cash dividends to participant accounts or by utilizing the dividends as additional debt service on the ESOP loan. Dividends payable on unallocated shares are not considered dividends for financial reporting purposes. Shares held by the ESOP trust are allocated to participant accounts based on the ratio of the current year principal and interest payments to the total of the current year and future years’ principal and interest to be paid on the employer loan. Compensation expense is recognized based on the average fair value of shares released for allocation to participant accounts during the year with a corresponding credit to stockholders’ equity. The ESOP loan was repaid in full during the quarter ended December 31, 2015 and all shares have been allocated to participants in the plan therefore no compensation expense was recognized for the three- and nine-month periods ended June 30, 2019 and 2018. The ESOP trust held 137,623 and 151,999 shares of Company common stock at June 30, 2019 and September 30, 2018, respectively.

Stock Based Compensation Plans
Stock Based Compensation Plans	10. The Company maintains two equity incentive plans under which stock options and restricted stock have been or can be granted, the 2010 Equity Incentive Plan (“2010 Plan”), approved by the Company’s shareholders in February 2010, and the 2016 Equity Incentive Plan (“2016 Plan”), approved by the Company’s shareholders in February 2016. The aggregate number of shares of the Company’s common stock available for issuance under the 2016 Plan may not exceed 88,000 shares, consisting of 66,000 stock options and 22,000 shares of restricted stock. At June 30, 2019, 8,658 shares of the Company’s common stock were available for issuance under the 2010 Plan as stock options and 11,991 shares of the Company’s common stock were available for issuance under the 2016 Plan, consisting of 10,555 stock options and 1,436 shares of restricted stock. Stock Options Under the plans, the Company may grant both non-statutory and incentive stock options that may not have a term exceeding ten years. In the case of incentive stock options, the aggregate fair value (determined at the time the incentive stock options are granted) which are first exercisable during any calendar year shall not exceed $100,000. Exercise prices generally may not be less than the fair market value of the underlying stock at the date of the grant. The terms of the plans also include provisions whereby all unearned options and restricted shares become immediately exercisable and fully vested upon a change in control. Stock options granted generally vest ratably over five years and are exercisable in whole or in part for a period up to ten years from the date of the grant. Compensation expense is measured based on the fair market value of the options at the grant date and is recognized ratably over the period during which the shares are earned (the vesting period). The fair market value of stock options granted is estimated at the date of grant using a binomial option pricing model. 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 nine-month period ended June 30, 2019 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 June 30, 2019, and changes during the nine-month period then ended is presented below. Weighted Average Remaining Weighted Contractual Aggregate Number of Average Term Intrinsic Shares Exercise Price (Years) Value (Dollars in thousands, except per share data) Outstanding at beginning of period 150,033 $ 24.88 Granted 2,400 59.23 Exercised (66,877) 14.21 Forfeited or expired (750) 40.09 Outstanding at end of period 84,806 $ 34.13 5.5 $ 2,237 Vested and expected to vest 84,806 $ 34.13 5.5 $ 2,237 Exercisable at end of period 45,479 $ 24.04 3.5 $ 1,635 The intrinsic value of stock options exercised during the nine-month period ended June 30, 2019 was $2.6 million. The intrinsic value of stock options exercised during the nine-month period ended June 30, 2018 was $2.8 million. The Company recognized compensation expense related to stock options of $18,000 and $54,000 for the three- and nine-month periods ended June 30, 2019, respectively. The Company recognized compensation expense related to stock options of $17,000 and $50,000 for the three- and nine-month periods ended June 30, 2018, respectively. At June 30, 2019, there was $192,000 of unrecognized compensation expense related to nonvested stock options. The compensation expense is expected to be recognized over the remaining vesting period of 4.4 years. Restricted Stock The vesting period of restricted stock granted under the plans is generally five years beginning one year after the date of grant of the awards. Compensation expense is measured based on the fair market value of the restricted stock at the grant date and is recognized ratably over the vesting period. Compensation expense related to restricted stock recognized for the three and nine-month periods ended June 30, 2019 was $44,000 and $129,000, respectively. Compensation expense related to restricted stock recognized for the three and nine-month periods ended June 30, 2018 was $37,000 and $111,000, respectively. A summary of the Company’s nonvested restricted shares activity as of June 30, 2019 and changes during the nine-month period then ended is presented below. Weighted Number Average of Grant Date Shares Fair Value Nonvested at October 1, 2018 14,812 $ 41.20 Granted 2,500 $ 59.23 Vested (3,653) $ 40.99 Forfeited (201) $ 40.09 Nonvested at June 30, 2019 13,458 $ 44.62 There were 3,653 restricted shares vested during the nine-month period ended June 30, 2019 with a total fair value of $216,000. There were 3,453 restricted shares that vested during the nine-month period ended June 30, 2018 with a total fair value of $195,000.

Derivative Financial Instruments
Derivative Financial Instruments	11. 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 accompanying 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.

Regulatory Capital
Regulatory Capital	12. 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 was phased in from 0.0% for 2015 to 2.5% by 2019. The capital conservation buffer was 1.875% for 2018 and 2.5% for 2019. The Company and Bank met all capital adequacy requirements to which they are subject as of June 30, 2019 and September 30, 2018. As of June 30, 2019, the most recent notification from the Federal Reserve Bank 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 1 risk-based, common equity Tier 1 risk-based and Tier 1 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 at either date.

Recent Accounting Pronouncements
Recent Accounting Pronouncements	13. The following are summaries of recently issued or adopted accounting pronouncements that impact the accounting and reporting practices of the Company: 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 , which provides an additional, optional transition method related to implementing the new leases standard. ASU 2018‑11 provides that companies can initially apply the new leases standard at adoption and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Management is evaluating the new guidance and expects to report increased assets and liabilities as a result of recording right-of-use assets and lease liabilities. However, based on current lease obligations, the adoption is expected to increase the Company’s consolidated balance sheet by less than 5% and not have a material impact on the Company’s and the Bank’s regulatory capital ratios. 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 implemented; 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 July 2019, the FASB voted to propose a delay in the effective date of ASU 2016-13 for smaller reporting companies (us defined by the SEC) and other non - SEC reporting entities. The proposal would delay the effective date to fiscal years beginning after December 15, 2022, including interim periods within those fiscal periods. The Company is a smaller reporting company and would quality for the delayed effective date if the proposal is approved by the FASB. 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.

Segment Reporting
Segment Reporting	14. The Company’s operations include three primary segments: core banking, SBA lending, and mortgage banking. The core banking segment originates residential, commercial and consumer loans and attracts deposits from its customer base. Net interest income from loans and investments that are 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 mortgage banking segment originates residential mortgage loans and sells them in the secondary market. Net gains on the sales of loans, income from derivative financial instruments and net interest income are the primary sources of revenue for the mortgage banking segment. The core banking segment is comprised primarily by 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. The mortgage banking segment operates as a separate division of the Bank and began operations in April 2018. 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.

Transaction-based fees, which include services such as wire fees, stop payment charges, statement rendering, and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Company fulfills the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. ATM and Interchange Fees : The Company earns ATM usage fees and interchange fees from debit cardholder transactions conducted through a payment network. ATM fees are recognized when the transaction occurs. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. Investment Advisory Income : The Company earns trust, insurance commissions, brokerage commissions and annuities income from its contracts with customers to manage assets for investment, and/or to transact on their accounts. These fees are primarily earned over time as the Company provides the contracted services and are generally assessed based on the market value of assets under management. Fees that are transaction based, including trade execution services, are recognized when the transaction is executed. Other related fees, which are based on a fixed fee schedule, are recognized when the services are rendered. Other Income : Other income from contracts with customers includes check cashing and cashier’s check fees, safe deposit box fees and cash advance fees. This revenue is recognized at the time the transaction is executed or over the period the Company satisfies the performance obligation.
