Presentation of Interim Information
Presentation of Interim Information	1. Presentation of Interim Information 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 originally owned 51% of Q2’s membership interests. On December 31, 2020, the Bank completed the acquisition of the minority interests in Q2, and Q2 became a wholly-owned subsidiary of the Bank. As part of the acquisition of the minority interests, the Bank paid total consideration of $3.1 million. The acquisition was accounted for as an equity transaction, and resulted in the reclassification of the noncontrolling interests of $695,000, the recognition of net deferred tax assets of $590,000 and a reduction of additional paid-in capital of $1.9 million. 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, 2021, the results of operations for the three- and nine-month periods ended June 30, 2021 and 2020, and the cash flows for the nine-month periods ended June 30, 2021 and 2020. 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, 2020 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.

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, 2021, which consisted of agency mortgage-backed securities, agency CMOs, privately-issued CMOs, privately-issued ABS, municipal bonds and SBA certificates, had a fair value as a percentage of amortized cost of 98.26%. The municipal securities are issued by municipal governments, and are generally secured by municipal project revenues or general obligations of the municipality. 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, 2021, the Company held eleven privately-issued CMO and ABS securities, acquired in a 2009 bank merger, with an aggregate amortized cost of $530,000 and fair value of $544,000 that have been downgraded to a substandard regulatory classification due to the security’s credit quality rating by various rating agencies. At June 30, 2021, one privately-issued CMO security and one privately-issued ABS were in a loss position, and had depreciated approximately 1.98% from the Company’s carrying value and were collateralized by residential mortgage loans. These securities had a total fair value of $396,000 and a total unrealized loss of $8,000 at June 30, 2021. Based on the independent third party analysis of the expected cash flows, management determined that no other-than-temporary impairment was required to be recognized on the privately issued CMO and ABS portfolios at June 30, 2021. While the Company did not have any additional credit-related impairment losses at June 30, 2021, additional deterioration in market and economic conditions may have an adverse impact on the credit quality of the portfolio, and therefore, require a credit related impairment charge in the future. The unrealized losses on agency mortgage-backed securities, agency 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 and nine-month periods ended June 30, 2021, the Company did not realize any gross gains or losses on sales of available for sale securities. During the nine-month period ended June 30, 2020, the Company realized gross gains on sales of available for sale securities of $15,000, and gross losses of $8,000. The Company did not realize any gross gains or losses on sales of available for sale securities during the three-month period ended June 30, 2020. Certain available for sale debt securities were pledged to secure FHLB borrowings at June 30, 2021 and September 30, 2020, and may be pledged to secure federal funds borrowings.

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, 2021 and September 30, 2020. There was no specific reserve included in the allowance for loan losses related to TDRs at June 30, 2021. There was $538,000 of specific reserve included in the allowance for loan losses related to TDRs at September 30, 2020.

At June 30, 2021 and September 30, 2020, the Company had committed to lend $1,000 to customers with outstanding loans classified as TDRs. There were principal charge-offs totaling $457,000 recorded as a result of TDRs during the nine-month period ended June 30, 2021. There were principal charge-offs totaling $59,000 recorded as a result of TDRs during the three-month period ended June 30, 2021. There were no principal charge-offs recorded as a result of TDRs during the three- and nine-month periods ended June 30, 2020. There were no provisions for loan losses related to TDRs for the three- and nine-month periods ended June 30, 2021. Provisions for loan losses related to TDRs were $665,000 for the three-month and nine-month periods ended June 30, 2020. 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 three and nine-month periods ended June 30, 2021 and 2020, the Company did not have any TDRs that were modified within the previous twelve months and for which there was a payment default. On March 22, 2020, the federal banking agencies issued an “Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus.” This guidance encourages financial institutions to work prudently with borrowers that may be unable to meet their contractual obligations because of the effects of COVID-19. The guidance indicates that, in consultation with the Financial Accounting Standards Board (“FASB”), the federal banking agencies concluded that short-term modifications (e.g., six months) made on a good faith basis to borrowers who were current as of the implementation date of a relief program are not TDRs. The Coronavirus Aid, Relief and Economic Security (“CARES”) Act was passed by Congress on March 27, 2020. The CARES Act also addressed COVID-19 related modifications and specified that COVID-19 related modifications on loans that were current as of December 31, 2019 are not TDRs. The Consolidated Appropriations Act of 2021, signed into law on December 27, 2020, further extended the relief from TDR accounting for qualified modifications to the earlier of January 1, 2022 or 60 days after the national emergency concerning COVID-19 terminates. At June 30, 2021, loans totaling $8.7 million remained under the Company’s payment extension program or a loan forbearance agreement, of which $8.6 million related to commercial real estate and commercial business loans and $127,000 related to residential real estate loans. These payment extensions or loan forbearance agreements are generally for periods of three months or less, but may be extended if the borrower continues to be impacted by the COVID-19 pandemic. SBA Loan Servicing Rights The Company originates loans to commercial customers under the SBA 7(a) program 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 SBA servicing rights are then amortized in proportion to and over the period of estimated net servicing income. Impairment of SBA servicing rights is assessed using the present value of estimated future cash flows. The aggregate fair value of SBA 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 SBA 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 SBA 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 other noninterest income in the consolidated statements of income. The unpaid principal balance of SBA loans serviced for others was $239.5 million, $209.1 million and $190.5 million at June 30, 2021, September 30, 2020 and June 30, 2020, respectively. Contractually specified late fees and ancillary fees earned on SBA loans were $32,000 and $69,000 for the three and nine-month periods ended June 30, 2021, respectively. Contractually specified late fees and ancillary fees earned on SBA loans were $23,000 and $53,000 for the three and nine-month periods ended June 30, 2020, respectively. Net servicing income (contractually specified servicing fees offset by direct servicing expenses) related to SBA loans was $591,000 and $1.6 million for the three and nine-month periods ended June 30, 2021, respectively. Net servicing income (contractually specified servicing fees offset by direct servicing expenses) related to SBA loans was $502,000 and $1.3 million for the three and nine-month periods ended June 30, 2020, respectively. Net servicing income and costs related to SBA loans are included in other noninterest income in the consolidated statements of income. An analysis of SBA loan servicing rights for the th

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, 2021 and September 30, 2020.

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, 2021. Securities Available for Sale and Equity Securities. Residential Mortgage Loans Held for Sale SBA and Single Tenant Net Lease Loans Held for Sale Derivative Financial Instruments 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 and liabilities (intrest rate lock commitments) measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the three and nine-month periods ended June 30, 2021 and 2020: Three Months Ended Nine Months Ended June 30, June 30, (In thousands) 2021 2020 2021 2020 Beginning balance $ 262 $ 5,678 $ 14,937 $ 3,269 Unrealized gains/(losses) recognized in earnings, net of settlements 1,777 11,328 (12,898) 13,737 Ending balance $ 2,039 $ 17,006 $ 2,039 $ 17,006 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 nine-month periods ended June 30, 2021 and 2020 attributable to Level 3 derivative assets and liabilities held at the balance sheet date were $2.0 million and $17.0 million, respectively. The table below presents information about significant unobservable inputs (Level 3) used in the valuation of derivative financial instruments measured at fair value on a recurring basis as of June 30, 2021 and September 30, 2020. Range of Inputs Range of Inputs (Weighted Average) (Weighted Average) Significant June 30, September 30, Financial Instrument Unobservable Inputs 2021 2020 Interest rate lock commitments Pull-through rate 0% - 100% (81%) 0% - 100% (80%) Direct costs to close 0.39% - 1.65% (0.95%) 0.31% - 1.01% (0.52%) Mortgage Servicing Rights . Impaired Loans 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, 2021 and September 30, 2020, 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, 2021 and September 30, 2020, the significant unobservable inputs used in the fair value measurement of impaired loans included discounts from appraised value ranging from 0.0% to 100.0% and 0.0% to 75.0%, respectively, and estimated costs to sell the collateral ranging from 0.0% to 6.0% and 0.0% to 12.0%, respectively. During the three and nine-month periods ended June 30, 2021, the Company recognized provisions for loan losses on impaired loans of $87,000 and $354,000, respectively. During the three and nine-month periods ended June 30, 2020, the Company recognized provisions for loan losses on impaired loans of $157,000 million and $2.1 million, respectively. SBA Loan Servicing Rights Other Real Estate Owned 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, 2021, 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 30.9% to 52.9% with a weighted average of 31.0%. At September 30, 2020, 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) of 30.9%. 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, 2021 and 2020. As previously discussed, management used different valuation methodologies related to SBA loans held for sale at June 30, 2021 and September 30, 2020, 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 the Company’s Level 3 financial assets of the fair value hierarchy for the three and nine-month periods ended June 30, 2021. Financial Instruments Recorded Using Fair Value Option. The Company has elected the fair value option for substantially all of its residential mortgage loans held for sale effective July 1, 2018, excluding participation interests acquired from correspondent lenders, and certain home equity lines of credit. 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, 2021 and September 30, 2020. 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, 2021 and September 30, 2020. Aggregate Aggregate Principal Fair Value Balance June 30, June 30, (In thousands) 2021 2021 Difference Residential mortgage loans held for sale $ 232,708 $ 225,051 $ 7,657 Aggregate Aggregate Principal Fair Value Balance September 30, September 30, (In thousands) 2020 2020 Difference Residential mortgage loans held for sale $ 208,493 $ 198,138 $ 10,355 The table below presents gains and losses and interest included in earnings related to financial assets measured at fair value under the fair value option for the three and nine-month periods ended June 30, 2021 and 2020: Three Months Ended Nine Months Ended June 30, June 30, (In thousands) 2021 2020 2021 2020 Gains (losses) – included in mortgage banking income $ 4,647 $ 2,271 $ 4,838 $ 5,627 Interest income 1,134 1,463 4,398 3,059 $ 5,781 $ 3,734 $ 9,236 $ 8,686 GAAP requires disclosure of fair value information about financial instruments for interim reporting periods, whether or not recognized in the consolidated balance sheet. 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. Fair Value Measurements Carrying Using: Amount Level 1 Level 2 Level 3 (In thousands) June 30, 2021: Financial assets: Cash and due from banks $ 14,388 $ 14,388 $ — $ — Interest-bearing deposits with banks 8,521 8,521 — — Interest-bearing time deposits 2,226 — 2,226 — Securities available for sale 207,628 — 207,628 — Securities held to maturity 1,923 — 2,168 — Residential mortgage loans held for sale 242,357 — 247,357 — Single tenant net lease loans held for sale 17,506 — — 17,506 SBA loans held for sale 17,511 — — 20,055 Loans, net 1,065,852 — — 1,109,243 FRB and FHLB stock 19,258 N/A N/A N/A Accrued interest receivable 7,011 — 7,011 — Residential mortgage loan servicing rights 47,413 — — 47,413 SBA loan servicing rights 4,365 — — 4,660 Derivative assets (included in other assets) 2,524 — 51 2,473 Equity securities (included in other assets) 102 102 — — Financial liabilities: Deposits 1,127,155 — — 1,127,955 Borrowings from FHLB 283,289 — 285,142 — Federal Reserve PPPLF borrowings 107,829 — 107,813 — Subordinated note 19,848 — 23,587 — Accrued interest payable 684 — 684 — Advance payments by borrowers for taxes and insurance 1,552 — 1,552 — Derivative liabilities (included in other liabilities) 1,014 — 580 434 Fair Value Measurements Carrying Using: Amount Level 1 Level 2 Level 3 (In thousands) September 30, 2020: Financial assets: Cash and due from banks $ 12,807 $ 12,807 $ — $ — Interest-bearing deposits with banks 20,919 20,919 — — Interest-bearing time deposits 2,964 — 2,964 — Securities available for sale 201,965 — 201,965 — Securities held to maturity 2,102 — 2,385 — Residential mortgage loans held for sale 263,406 — 263,519 — SBA loans held for sale 22,119 — 24,666 — Loans, net 1,090,063 — — 1,152,962 FRB and FHLB stock 17,293 N/A N/A N/A Accrued interest receivable 6,462 — 6,462 — Residential mortgage loan servicing rights 21,703 — — 21,703 SBA loan servicing rights 3,748 — — 3,934 Derivative assets (included in other assets) 15,163 — 226 14,937 Equity securities (included in other assets) 66 66 — — Financial liabilities: Deposits 1,048,076 — — 1,050,569 Borrowings from FHLB 310,858 — 310,766 — Federal Reserve PPPLF borrowings 174,834 — 174,808 — Subordinated note 19,797 — 23,788 — Accrued interest payable 683 — 683 — Advance payments by borrowers for taxes and insurance 2,615 — 2,615 — Derivative liabilities (included in other liabilities) 1,827 — 1,827 — The methods and assumptions used to estimate fair value are described as follows: Carrying amount is the estimated fair value for cash and cash equivalents, interest-bearing time deposits, accrued interest receivable and payable, advance payments by borrowers for taxes and insurance, demand deposits and other transaction accounts. The fair value of loans (excluding loans held for sale), fixed-maturity certificates of deposit, and borrowed funds is based on discounted cash flows using current market rates applied to the estimated life and credit risk of the instrument. It is not practicable to determine the fair value of FHLB and other restricted stock due to restrictions placed on its transferability. The methods and assumptions used to estimate the fair value of investment securities, loans held for sale, loan servicing rights, and derivative assets and liabilities are discussed previously in Note 7. The methods utilized to measure the fair value of financial instruments at June 30, 2021 and September 30, 2020 represent an approximation of exit price, but an actual exit price may differ.

Employee Stock Ownership Plan
Employee Stock Ownership Plan	8. Employee Stock Ownership Plan 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 or nine-month periods ended June 30, 2021 and 2020. The ESOP trust held 111,986 and 119,654 shares of Company common stock at June 30, 2021 and September 30, 2020, respectively.

Stock Based Compensation Plans
Stock Based Compensation Plans	9. Stock Based Compensation Plans The Company maintains two equity incentive plans under which stock options and restricted stock have been or may 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, 2021, there were no remaining shares of the Company’s common stock available for issuance under the 2010 Plan. At June 30, 2021, 1,520 shares of the Company’s common stock were available for issuance under the 2016 Plan, of which 500 shares were available for restricted stock and 1,020 shares were available for stock options. The Company generally issues new shares under the 2016 Plan from its authorized but unissued shares. The Company accounts for any forfeitures as they occur, and any previously recognized compensation cost for an award is reversed in the period the award is forfeited. 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, 2021 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, 2021, and changes during the nine-month period then ended is presented below.

The Company recognized compensation expense related to stock options of $22,000 and $69,000 for the three and nine-month periods ended June 30, 2021, respectively. The Company recognized compensation expense related to stock options of $22,000 and $64,000 for the three and nine-month periods ended June 30, 2020, respectively. At June 30, 2021, there was $131,000 of unrecognized compensation expense related to nonvested stock options. The compensation expense is expected to be recognized over a weighted average period of 2.98 years. Cash received from the exercise of stock options and the tax benefit from the exercise of stock options totaled $4,000 and $6,000, respectively, for the nine-month period ended June 30, 2021. Cash received from the exercise of stock options and the tax benefit from the exercise of stock options were $148,000 and $134,000, respectively, for the nine-month period ended June 30, 2020. 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, 2021 was $43,000 and $138,000, respectively. Compensation expense related to restricted stock recognized for the three and nine-month periods ended June 30, 2020 was $49,000 and $144,000, respectively. A summary of the Company’s nonvested restricted shares activity as of June 30, 2021 and changes during the nine-month period then ended is presented below.

Derivative Financial Instruments
Derivative Financial Instruments	10. 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 loans 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 consolidated balance sheets at fair value in accordance with FASB ASC 815, Derivatives and Hedging 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 Company may be required to post margin collateral to derivative counterparties based on agreements with the dealers. At June 30, 2021 and September 30, 2020, the Company had cash collateral posted with certain derivative counterparties of $2.2 million and $3.0 million, respectively, against its derivative obligations. Cash collateral related to derivative contracts is recorded in interest-bearing deposits with banks or other assets in the consolidated balance sheets.

Regulatory Capital
Regulatory Capital	11. Regulatory Capital The Bank is 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 Bank must meet specific capital guidelines that involve quantitative measures of the Bank’s assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The 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 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 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 2.50%for 2021 and 2020. The Bank met all capital adequacy requirements to which it was subject as of June 30, 2021 and September 30, 2020. As of June 30, 2021, 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. The Company is not subject to the Federal Reserve Bank’s consolidated capital requirements because it has less than $3 billion in total consolidated assets. However, management has elected to disclose the Company’s Consolidated capital amounts and ratios in addition to the Bank’s required disclosures in the table below. No amount was deducted from capital for interest-rate risk at either date.

Segment Reporting
Segment Reporting	13. Segment Reporting 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. 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 three 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.

Leases
Leases	15. Leases A lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. The Company is a lessor in certain leasing agreements, such as for office space, and is a lessee in others, such as for certain office space and equipment. The Company’s operating leases have terms that expire at different dates through August 2028, and some include options to extend the leases in five year increments. On October 1, 2019, the Company adopted FASB ASC 842 and all subsequent updates that modified FASB ASC 842. For the Company, this update primarily affected the accounting treatment for operating lease agreements. With the adoption of FASB ASC 842, operating lease agreements are required to be recognized on the consolidated balance sheet as a “right of use” (“ROU”) asset and a corresponding lease liability. All of the Company’s leases are classified as operating leases, and therefore, were previously not recognized on the Company’s consolidated balance sheet. The Company’s right to use an asset over the life of a lease is recorded as an ROU asset included in other assets other liabilities The calculated amount of the ROU assets and lease liabilities are impacted by the length of the lease term and the discount rate used to calculate the present value of minimum lease payments. Regarding the discount rate, FASB ASC 842 requires the use of the rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term. For operating leases existing prior to October 1, 2019, the rate for the remaining lease term as of October 1, 2019 was used. Leases with an initial term of 12 months or less are not recorded on the balance sheet and the Company recognizes lease expense for these leases on a straight-line basis over the term of the lease. Certain leases include one or more options to renew, with renewal terms that can extend the lease term from one Lease expense for the three and nine–month periods ended June 30, 2021 was $573,000 and $1.6 million, respectively. Lease expense for the three and nine-month periods ended June 30, 2020 was $493,000 and $1.4 million, respectively. The components of lease expense for the three and nine-month periods ended June 30, 2021 and 2020 were as follows: Three Months Ended Nine Months Ended Three Months Ended Nine Months Ended June 30, June 30, June 30, June 30, 2021 2021 2020 2020 Operating lease cost $ 323 $ 957 $ 356 $ 941 Short-term lease cost 250 662 137 452 $ 573 $ 1,619 $ 493 $ 1,393 Future minimum commitments due under these lease agreements as of June 30, 2021 are as follows, including renewal options that are reasonably certain to be exercised: 2021 (remaining three months) $ 264 2022 987 2023 654 2024 562 2025 445 Thereafter 5,478 Total lease payments 8,390 Less imputed interest (1,875) Total $ 6,515 The lease term and discount rate at June 30, 2021 and September 30, 2020 were as follows: June 30, September 30, 2021 2020 Weighted-average remaining lease term (years) 20.4 22.6 Weighted-average discount rate 2.40 % 2.75 % Supplemental cash flow information for the nine–month periods ended June 30, 2021 and 2020 related to leases was as follows: 2021 2020 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 1,016 $ 874 ROU assets obtained in exchange for lease obligations: Operating leases $ 2,038 $ 8,816
