Organization and Summary of Significant Accounting Policies
Organization and Summary of Significant Accounting Policies	​ NOTE 1: Organization and Summary of Significant Accounting Policies Organization. The Bank is primarily engaged in providing a full range of banking and financial services to individuals and corporate customers in its market areas. The Bank and Company are subject to competition from other financial institutions. The Bank and Company are subject to the regulation of certain federal and state agencies and undergo periodic examinations by those regulatory authorities. Basis of Financial Statement Presentation. Principles of Consolidation. Use of Estimates. On July 1, 2020, Financial Instruments – Credit Losses which created material changes to the existing critical accounting policy that existed at June 30, 2020 . Effective July 1, 2020 , the significant accounting policy which was considered to be the most critical in preparing the Company’s consolidated financial statements is the determination of the allowance for credit losses (“ACL”) on loans. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for credit losses, and estimated fair values of purchased loans. Cash and Cash Equivalents. Interest-bearing Time Deposits. Available for Sale Securities. Premiums and discounts on debt securities are amortized or accreted as adjustments to income over the estimated life of the security using the level yield method. Realized gains or losses on the sale of securities is based on the specific identification method. The fair value of securities is based on quoted market prices or dealer quotes. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities. The Company does not invest in collateralized mortgage obligations that are considered high risk. For AFS securities with fair value less than amortized cost that management has no intent to sell and believes that it more likely than not will not be required to sell prior to recovery, only the credit loss component of the impairment is recognized in earnings, while the noncredit loss is recognized in accumulated other comprehensive income (loss). The credit loss component recognized in earnings is identified as the amount of principal cash flows not expected to be received over the remaining term of the security as projected based on cash flow projections, and is recorded to the ACL, by a charge to provision for credit losses. Accrued interest receivable is excluded from the estimate of credit losses. Both the ACL and the adjustment to net income may be reversed if conditions change. However, if the Company intends to sell an impaired AFS security, or, if it is more likely than not the Company will be required to sell such a security before recovering its amortized cost basis, the entire impairment amount would be recognized in earnings with a corresponding adjustment to the security’s amortized cost basis. Because the security’s amortized cost basis is adjusted to fair value, there is no ACL in this situation. At adoption of ASU 2016-13, no impairment on AFS securities was attributable to credit. The Company will evaluate impaired AFS securities at the individual level on a quarterly basis, and will consider such factors including, but not limited to: the extent to which the fair value of the security is less than the amortized cost basis; adverse conditions specifically related to the security, an industry, or geographic area; the payment structure of the security and likelihood of the issuer to be able to make payments that may increase in the future; failure of the issuer to make scheduled interest or principal payments; any changes to the rating of the security by a rating agency; and the ability and intent to hold the security until maturity. A qualitative determination as to whether any portion of the impairment is attributable to credit risk is acceptable. There were no credit related factors underlying unrealized losses on AFS securities at June 30, 2021, and June 30, 2020. Changes in the ACL are recorded as expense. Losses are charged against the ACL when management believes the uncollectability of an AFS debt security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Federal Reserve Bank and Federal Home Loan Bank Stock. Loans. Interest on loans is accrued based upon the principal amount outstanding. The accrual of interest on loans is discontinued when, in management’s judgment, the collectability of interest or principal in the normal course of business is doubtful. The Company complies with regulatory guidance which indicates that loans should be placed in nonaccrual status when 90 days past due, unless the loan is both well-secured and in the process of collection. A loan that is “in the process of collection” may be subject to legal action or, in appropriate circumstances, through other collection efforts reasonably expected to result in repayment or restoration to current status in the near future. A loan is considered delinquent when a payment has not been made by the contractual due date. At June 30, 2021, some loans were modified under the terms of the Coronavirus Aid, Relief and Economic Security Act (the CARES Act), which provides that loans modified after March 1, 2020, due to the COVID-19 pandemic, and which were otherwise current at December 31, 2019, need not be accounted for as troubled debt restructurings (TDRs). While these loans may not have met the contractual due dates of payments under their previous terms, so long as they were compliant with the terms of the modification made under the CARES Act, they would not have been reported as delinquent at June 30, 2020 or June 30, 2021. See further disclosure in Note 3: Loans and Allowance for Loan Losses. Interest income previously accrued but not collected at the date a loan is placed on nonaccrual status is reversed against interest income. Cash receipts on a nonaccrual loan are applied to principal and interest in accordance with its contractual terms unless full payment of principal is not expected, in which case cash receipts, whether designated as principal or interest, are applied as a reduction of the carrying value of the loan. A nonaccrual loan is generally returned to accrual status when principal and interest payments are current, full collectability of principal and interest is reasonably assured, and a consistent record of performance has been demonstrated. The ACL is a valuation account that is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on the loans, and is established through provision for credit losses charged to current earnings. The ACL is increased by the provision for losses on loans charged to expense and reduced by loans charged off, net of recoveries. Loans are charged off in the period deemed uncollectible, based on management’s analysis of expected cash flows (for non-collateral dependent loans) or collateral value (for collateral-dependent loans). Subsequent recoveries of loans previously charged off, if any, are credited to the allowance when received. Management estimates the ACL using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Adjustments may be made to historical loss information for differences identified in current loan-specific risk characteristics, such as differences in underwriting standards or terms; lending review systems; experience, ability, or depth of lending management and staff; portfolio growth and mix; delinquency levels and trends; as well as for changes in environmental conditions, such as changes in economic activity or employment, agricultural economic conditions, property values, or other relevant factors. The Company generally incorporates a reasonable and supportable forecast period of four quarters, and a four-quarter, straight-line reversion period to return to long-term historical averages. The ACL is measured on a collective (pool) basis when similar risk characteristics exist. For loans that do not share general risk characteristics with the collectively evaluated pools, the Company estimates credit losses on an individual loan basis, and these loans are excluded from the collectively evaluated pools. An ACL for an individually evaluated loan is recorded when the amortized cost basis of the loan exceeds the discounted estimated cash flows using the loan’s initial effective interest rate or the fair value, less estimated costs to sell, of the collateral for certain collateral dependent loans. For the collectively evaluated pools, the Company segments the loan portfolio primarily by loan purpose and collateral into 24 pools, which are homogeneous groups of loans that possess similar loss potential characteristics. The Company primarily utilizes the discounted cash flow (“DCF”) methodology for measurement of the required ACL. For a limited number of pools with a relatively small balance of unpaid principal balance, the Company utilized the remaining life method. The DCF model implements probability of default (“PD”) and loss given default (“LGD”) calculations at the instrument level. PD and LGD are determined based on statistical analysis and correlation of historical losses with various economic factors over time. In general, the Company’s losses have not correlated well with economic factors, and the Company has utilized peer data where more appropriate. The Company defines a default as an event of charge off, an adverse (substandard or worse) internal credit rating, becoming delinquent 90 days or more, or being placed on nonaccrual status. A PD/LGD estimate is applied to a projected model of the loan’s cashflow, including principal and interest payments, with consideration for prepayment speeds, principal curtailments, and recovery lag. Prior to the July 1, 2020, adoption of ASU 2016-13, the allowance for loan and lease losses (ALLL) represented management’s best estimate of probable losses in the existing loan portfolio at the end of the reporting period. Integral to the methodology for determining the adequacy of the ALLL was portfolio segmentation and impairment measurement. Under the Company’s methodology, loans were first segmented into 1) those comprising large groups of homogeneous loans which are collectively evaluated for impairment and 2) all other loans which are individually evaluated. Those loans in the second category were further segmented utilizing a defined grading system which involves categorizing loans by severity of risk based on conditions that may affect the ability of the borrowers to repay their debt, such as current financial information, collateral valuations, historical payment experience, credit documentation, public information, and current trends. Loans were considered impaired if, based on current information and events, it was considered probable that the Company would be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement, and was generally based on the fair value, less estimated costs to sell, of the loan’s collateral. If the loan was not collateral-dependent, the measurement of impairment was based on the present value of expected future cash flows discounted at the historical effective interest rate, or the observable market price of the loan. Impairment identified through this evaluation process was a component of the ALLL. If a loan was not considered impaired, it was grouped together with loans having similar characteristics (i.e., the same risk grade), and an ALLL was based upon a quantitative factor (historical average charge-offs) and qualitative factors such as changes in lending policies; national, regional, and local economic conditions; changes in mix and volume of portfolio; experience, ability, and depth of lending management and staff; entry to new markets; levels and trends of delinquent, nonaccrual, special mention, and classified loans; concentrations of credit; changes in collateral values; agricultural economic conditions; and regulatory risk. Prior to the July 1, 2020, adoption of ASU 2016-13, loans acquired in an acquisition that had evidence of credit quality deterioration since origination and for which it was probable that the Company would be unable to collect all contractually required payments receivable were considered purchased credit impaired (“PCI”). PCI loans were individually evaluated and recorded at fair value at the date of acquisition with no initial ALLL based on a DCF methodology that considered various factors including the type of loan and related collateral, classification status, fixed or variable interest rate, term of loan and whether or not the loan was amortizing, and a discount rate reflecting the Company’s assessment of risk inherent in the cash flow estimates. The difference between the DCFs expected at acquisition and the investment in the loan, or the “accretable yield,” was recognized as interest income on a level-yield method over the life of the loan. Contractually required payments for interest and principal that exceed the DCFs expected at acquisition, or the “non-accretable difference,” were not recognized on the balance sheet and did not result in any yield adjustments, loss accruals or valuation allowances. Increases in expected cash flows, including prepayments, subsequent to the initial investment were recognized prospectively through adjustment of the yield on the loan over its remaining life. Decreases in expected cash flows were recognized as impairment. ALLL on PCI loans reflected only losses incurred after the acquisition (meaning the present value of all cash flows expected at acquisition that ultimately were not to be received). Subsequent to the July 1, 2020, adoption of ASU 2016-13, loans acquired in a business combination that have experienced more-than-insignificant deterioration in credit quality since origination are considered purchased credit deteriorated (“PCD”) loans. At the acquisition date, an estimate of expected credit losses is made for groups of PCD loans with similar risk characteristics and individual PCD loans without similar risk characteristics. This initial ACL is allocated to individual PCD loans and added to the purchase price or acquisition date fair values to establish the initial amortized cost basis of the PCD loans. As the initial ACL is added to the purchase price, there is no credit loss expense recognized upon acquisition of a PCD loan. Any difference between the unpaid principal balance of PCD loans and the amortized cost basis is considered to relate to non-credit factors and results in a discount or premium. Discounts and premiums are recognized through interest income on a level-yield method over the life of the loans. Upon adoption of ASU 2016-13, the amortized cost basis of the PCD assets were adjusted to reflect the addition of $434,000 to the ACL. The remaining noncredit discount, based on the adjusted amortized cost basis, will be accreted into interest income at the effective interest rate as of July 1, 2020. Loan fees and certain direct loan origination costs are deferred, and the net fee or cost is recognized as an adjustment to interest income using the interest method over the contractual life of the loans. Off-Balance Sheet Credit Exposures. Off-balance sheet credit instruments include commitments to make loans, and commercial letters of credit, issued to meet customer financing needs. The Company’s exposure to credit loss in the event of non-performance by the other party to the financial instrument for off-balance sheet loan commitments is represented by the contractual amount of those instruments. Such financial instruments are recorded when they are funded. The ACL on off-balance sheet credit exposures is estimated by loan pool on a quarterly basis under the current CECL model using the same methodologies as portfolio loans, taking into consideration the likelihood that funding will occur and is included in other liabilities on the Company’s consolidated balance sheets. The Company records an ACL on off-balance sheet credit exposures, unless the commitments to extend credit are unconditionally cancelable. In prior periods the charge for credit loss expense for off-balance sheet credit exposures was included in other non-interest expense in the Company’s consolidated statements of income, whereas under updated regulatory accounting guidelines, that figure is combined with the provision for credit losses beginning July 1, 2020. Foreclosed Real Estate. Valuations are periodically performed by management, and an allowance for losses is established by a charge to operations if the carrying value of a property exceeds its estimated fair value, less estimated selling costs. Loans to facilitate the sale of real estate acquired in foreclosure are discounted if made at less than market rates. Discounts are amortized over the fixed interest period of each loan using the interest method. Premises and Equipment. Depreciation is computed by use of straight-line and accelerated methods over the estimated useful lives of the assets. Estimated lives are generally seven three Bank Owned Life Insurance. Intangible Assets. five Goodwill. Income Taxes. the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Company determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more likely than not means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to the management’s judgment. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. The Company recognizes interest and penalties on income taxes as a component of income tax expense. The Company files consolidated income tax returns with its subsidiaries, the Bank and SB Real Estate Investments, LLC, with a tax year ended June 30. Southern Bank Real Estate Investments, LLC files a separate REIT return for federal tax purposes, and also files state income tax returns with a tax year ended December 31. Incentive Plans. The Company accounts for its Equity Incentive Plan (EIP), and Omnibus Incentive Plan (OIP) in accordance with ASC 718, “Share-Based Payment.” Compensation expense is based on the market price of the Company’s stock on the date the shares are granted and is recorded over the vesting period. The difference between the grant-date fair value and the fair value on the date the shares are considered earned represents a tax benefit to the Company that is recorded as an adjustment to income tax expense. Outside Directors’ Retirement. In the event that the participant dies before collecting any or all of the benefits, the Bank shall pay the participant’s beneficiary. No benefits shall be payable to anyone other than the beneficiary, and shall terminate on the death of the beneficiary. Stock Options. C Earnings Per Share. Comprehensive Income. Transfers Between Fair Value Hierarchy Levels. Revisions. The following paragraphs summarize the impact of new accounting pronouncements: In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) - Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 modifies the disclosure requirements on fair value measurements in Topic 820. The amendments in this update remove disclosures that no longer are considered cost beneficial, modify/clarify the specific requirements of certain disclosures, and add disclosure requirements identified as relevant. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, with early adoption permitted for certain removed and modified disclosures. Adoption of this standard did not have a significant impact on the Company’s consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326), which the Company adopted July 1, 2020. The Update amended guidance on reporting credit losses for financial assets held at amortized cost basis and available for sale debt securities. For financial assets held at amortized cost basis, Topic 326 eliminated the probable initial recognition threshold in current GAAP and, instead, requires an entity to reflect its current estimate of all expected credit losses. The Update affects loans, debt securities, trade receivables, net investments in leases, off balance sheet credit exposures, and any other financial assets not excluded from the scope that have the contractual right to receive cash. Adoption was applied on a modified retrospective basis, through a cumulative-effect adjustment to retained earnings. Adoption resulted in an increase to the ACL of $8.9 million, related to the transition from the incurred loss model to the CECL ACL model, and an increase of $434,000 related to the transition from PCI to PCD methodology, relative to the ALLL as of June 30, 2020. The Company also recorded an adjustment to the reserve for unfunded commitments recorded in other liabilities of $268,000. The impact at adoption was reflected as an adjustment to beginning retained earnings, net of income taxes, in the amount of $7.2 million. In accordance with the new standard, management did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption. The adoption of ASU 2016-13 in fiscal 2021 could also impact the Company’s future earnings, perhaps materially The following table illustrates the impact of adoption of ASU 2016-13: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ July 1, 2020 ​ As reported As reported Impact of ​ under prior to adoption (dollars in thousands) ASU 2016-13 ASU 2016-13 ASU 2016-13 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Loans receivable ​ $ 2,142,363 ​ $ 2,141,929 ​ $ 434 Allowance for credit losses on loans: ​ ​ ​ ​ ​ ​ ​ ​ ​ Real Estate Loans: ​ ​ ​ ​ ​ ​ ​ ​ ​ Residential ​ 8,396 ​ 4,875 ​ 3,521 Construction ​ 1,889 ​ 2,010 ​ (121) Commercial ​ 15,988 ​ 12,132 ​ 3,856 Consumer loans ​ 2,247 ​ 1,182 ​ 1,065 Commercial loans ​ 5,952 ​ 4,940 ​ 1,012 Total allowance for credit losses on loans ​ $ 34,472 ​ $ 25,139 ​ $ 9,333 Total allowance for credit losses on off-balance sheet credit exposures ​ $ 2,227 ​ $ 1,959 ​ $ 268 ​ The above table includes the impact of ASU 2016-13 adoption for PCD assets previously classified as PCI. The change in the ACL includes $434,000 attributable to residential and commercial real estate loans, and the amortized cost basis of loans receivable was increased for those loans by that total amount. In March 2020, the CARES Act was signed into law, creating a forbearance program for federally backed mortgage loans, protects borrowers from negative credit reporting due to loan accommodations related to the National Emergency, and provides financial institutions the option to temporarily suspend certain requirements under U.S. GAAP related to troubled debt restructurings (TDR) for a limited period of time to account for the effects of COVID-19. The Company has elected to not apply ASC Subtopic 310-40 for loans eligible under the CARES Act, based on the modification’s (1) relation to COVID-19, (2) execution for a loan that was not more than 30-days past due as of December 31, 2019, and (3) execution between March 1, 2020, and the earlier of the date that falls 60 days following the termination of the declared National Emergency, or December 31, 2020. The 2021 Consolidated Appropriations Act, signed into law in December 2020, extended the window during which loans may be modified without classification as TDRs under ASC Subtopic 310-40, to the earlier of January 1, 2022, or 60 days following the termination of the declared National Emergency.

At June 30, 2021 there were two pooled trust preferred securities with an estimated fair value of $720,000 and unrealized losses of $257,000 in a continuous unrealized loss position for twelve months or more. These unrealized losses were primarily due to the long-term nature of the pooled trust preferred securities and a reduced demand for these securities, and concerns regarding the financial institutions that issued the underlying trust preferred securities. The June 30, 2021, cash flow analysis for these two securities indicated it is probable the Company will receive all contracted principal and related interest projected. The cash flow analysis used in making this determination was based on anticipated default, recovery, and prepayment rates, and the resulting cash flows were discounted based on the yield spread anticipated at the time the securities were purchased. Other inputs include the actual collateral attributes, which include credit ratings and other performance indicators of the underlying financial institutions, including profitability, capital ratios, and asset quality. Assumptions for these two securities included prepayments averaging 1.8 percent, annually, annual defaults averaging 220 basis points over the next two years, and 80 basis points thereafter, and a recovery rate averaging ten percent of gross defaults, lagged two years. One of these two securities has continued to receive cash interest payments in full since the Company’s purchase; the other security received principal-in-kind (PIK), in lieu of cash interest, for a period of time following the recession and financial crisis which began in 2008, but resumed cash interest payments during fiscal 2014. The Company's cash flow analysis indicates that cash interest payments are expected to continue for both securities. Because the Company does not intend to sell these securities and it is likely that the Company will not be required to sell these securities prior to recovery of their amortized cost basis, which may be maturity, the Company has not recorded an ACL on these securities. The Company does not believe any other individual unrealized loss as of June 30, 2021, is the result of a credit loss. However, the Company could be required to recognize an ACL in future periods with respect to its available for sale investment securities portfolio. Credit losses recognized on investments. ​

At June 30, 2021, the Bank had purchased participations in 23 loans totaling $83.0 million, as compared to 23 loans totaling $58.2 million at June 30, 2020. Residential Mortgage Lending. The Company also originates loans secured by multi-family residential properties that are often located outside the Company’s primary lending area but made to borrowers who operate within our primary market area. The majority of the multi-family residential loans that are originated by the Company are amortized over periods generally up to 25 years, with balloon maturities typically up to ten years. Both fixed and adjustable interest rates are offered and it is typical for the Company to include an interest rate “floor” and “ceiling” in the loan agreement. Generally, multi-family residential loans do not exceed 85% of the lower of the appraised value or purchase price of the secured property. General risks related to multi-family residential lending include rental demand and supply, rental rates, and vacancies, as well as collateral values and borrower leverage. Commercial Real Estate Lending. million in commercial real estate loans are secured by properties located outside our primary lending area. Risks to owner-occupied commercial real estate lending generally include the continued profitable operation of the borrower’s enterprise, as well as general collateral values, and may be heightened by unique, specific uses of the property serving as collateral. Non-owner-occupied commercial real estate lending risks include tenant demand and performance, lease rates, and vacancies, as well as collateral values and borrower leverage. These factors may be influenced by general economic conditions in the region, or in the United States generally. Risks to lending on farmland include unique factors such as commodity prices, yields, input costs, and weather, as well as farmland values. Most commercial real estate loans originated by the Company generally are based on amortization schedules of up to 25 years with monthly principal and interest payments. Generally, the interest rate received on these loans is fixed for a maturity for up to ten years, with a balloon payment due at maturity. Alternatively, for some loans, the interest rate adjusts at least annually after an initial period up to seven years. The Company typically includes an interest rate “floor” in the loan agreement. Generally, improved commercial real estate loan amounts do not exceed 80% of the lower of the appraised value or the purchase price of the secured property. Agricultural real estate terms offered differ slightly, with amortization schedules of up to 25 years with an 80% loan-to-value ratio, or 30 years with a 75% loan-to-value ratio. Construction Lending. six 12 While the Company typically utilizes relatively short maturity periods to closely monitor the inherent risks associated with construction loans for these loans, weather conditions, change orders, availability of materials and/or labor, and other factors may contribute to the lengthening of a project, thus necessitating the need to renew the construction loan at the balloon maturity. Such extensions are typically executed in incremental three month periods to facilitate project completion. The Company’s average term of construction loans is approximately eight months. During construction, loans typically require monthly interest only payments which may allow the Company an opportunity to monitor for early signs of financial difficulty should the borrower fail to make a required monthly payment. Additionally, during the construction phase, the Company typically performs interim inspections which further allow the Company opportunity to assess risk. At June 30, 2021, construction loans outstanding included 48 loans, totaling $28.5 million, for which a modification had been agreed to. At June 30, 2020, construction loans outstanding included 77 loans, totaling $48.8 million, for which a modification had been agreed to. In general, these modifications were solely for the purpose of extending the maturity date due to conditions described above, pursuant to the Company’s normal underwriting and monitoring procedures. As these modifications were not executed due to financial difficulty on the part of the borrower, they were not accounted for as troubled debt restructurings (TDRs); nor were they made pursuant to exemptions provided under the CARES Act. Under the CARES Act, financial institutions have the option to temporarily suspend certain requirements under U.S. GAAP related to TDRs for a limited period of time to account for the effects of COVID-19. Loans modified under the CARES Act did not include any construction loans with drawn balances at June 30, 2021. Consumer Lending Home equity lines of credit (HELOCs) are secured with a deed of trust and are issued up to 100% of the appraised or assessed value of the property securing the line of credit, less the outstanding balance on the first mortgage and are typically issued for a term of ten years. Interest rates on the HELOCs are generally adjustable. Interest rates are based upon the loan-to-value ratio of the property with better rates given to borrowers with more equity. Risks related to HELOC lending generally include the stability of borrower income and collateral values. Automobile loans originated by the Company include both direct loans and a smaller amount of loans originated by auto dealers. The Company generally pays a negotiated fee back to the dealer for indirect loans. Typically, automobile loans are made for terms of up to 60 months for new and used vehicles. Loans secured by automobiles have fixed rates and are generally made in amounts up to 100% of the purchase price of the vehicle. Risks to automobile and other consumer lending generally include the stability of borrower income and borrower willingness to repay. Commercial Business Lending Allowance for Credit Losses ​ ● economic conditions and projections as provided by Moody’s Analytics, including baseline and downside scenarios were utilized in the Company’s estimate at June 30, 2021. Economic factors considered in the projections included national and state levels of unemployment, and national and state rates of inflation-adjusted growth in the gross domestic product. Economic conditions are considered to be a moderate and declining risk factor; ​ ● the pace of growth of the Company’s loan portfolio, exclusive of acquisitions or government guaranteed loans, relative to overall economic growth. This measure remains elevated, but continued to moderate in the most recent quarter, and is considered to be a moderate and declining risk factor; ​ ● levels and trends for loan delinquencies nationally and in the region. This measure as reported remains relatively stable, but management considered the potential that the measure remains under-reported due to the availability of modifications under the CARES Act. The level of uncertainty about loan delinquencies is considered to be diminishing. This is considered to be an elevated but declining risk factor; ​ ● exposure to the hotel industry, in particular, metropolitan area hotels more impacted by activity restrictions and a lack of business or convention-related travel. This is considered to be an elevated and stable risk factor. ​ Management considered the impact of the COVID-19 pandemic on its consumer and business borrowers, particularly those business borrowers most affected by efforts to contain the pandemic, including our borrowers in the retail and multi-tenant retail industry, restaurants, and hotels, when making qualitative factor adjustments. To date, various relief efforts, notably including the availability of forgivable Paycheck Protection Program (PPP) loans to borrowers and deferrals or modifications available as encouraged by banking regulatory authorities and the CARES Act, have resulted in limited impact on the Company’s credit quality indicators, as is true of the industry generally. It is possible that the ongoing adverse effects of the pandemic may not be offset by future relief efforts, which could cause the outlook for economic conditions and levels and trends of past-due loans to significantly worsen, and require additions to the ACL. ​ The following tables present the balance in the ACL and the recorded investment in loans (excluding loans in process and deferred loan fees) based on portfolio segment as of June 30, 2021 and 2020, and activity in the ACL and ALLL for the fiscal years ended June 30, 2021, 2020, and 2019: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (dollars in thousands) Residential ​ ​ Construction ​ Commercial ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2021 Real Estate Real Estate Real Estate Consumer Commercial Total Allowance for credit losses: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Balance, beginning of period ​ $ 4,875 ​ $ 2,010 ​ $ 12,132 ​ $ 1,182 ​ $ 4,940 ​ $ 25,139 Impact of CECL adoption ​ ​ 3,521 ​ ​ (121) ​ ​ 3,856 ​ ​ 1,065 ​ ​ 1,012 ​ ​ 9,333 Provision (benefit) charged to expense ​ ​ 2,973 ​ ​ 281 ​ ​ (1,364) ​ ​ (1,232) ​ ​ (1,260) ​ ​ (602) Losses charged off ​ ​ (180) ​ ​ — ​ ​ (90) ​ ​ (146) ​ ​ (318) ​ ​ (734) Recoveries ​ ​ 3 ​ ​ — ​ ​ 1 ​ ​ 47 ​ ​ 35 ​ ​ 86 Balance, end of period ​ $ 11,192 ​ $ 2,170 ​ $ 14,535 ​ $ 916 ​ $ 4,409 ​ $ 33,222 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (dollars in thousands) Residential ​ Construction Commercial ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2020 Real Estate Real Estate Real Estate Consumer Commercial Total Allowance for loan losses: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Balance, beginning of period ​ $ 3,706 ​ $ 1,365 ​ $ 9,399 ​ $ 1,046 ​ $ 4,387 ​ $ 19,903 Provision charged to expense ​ ​ 1,529 ​ ​ 645 ​ ​ 2,730 ​ ​ 300 ​ ​ 798 ​ ​ 6,002 Losses charged off ​ ​ (379) ​ ​ — ​ ​ (12) ​ ​ (189) ​ ​ (273) ​ ​ (853) Recoveries ​ ​ 19 ​ ​ — ​ ​ 15 ​ ​ 25 ​ ​ 28 ​ ​ 87 Balance, end of period ​ $ 4,875 ​ $ 2,010 ​ $ 12,132 ​ $ 1,182 ​ $ 4,940 ​ $ 25,139 Ending Balance: individually evaluated for impairment ​ $ — ​ $ — ​ $ — ​ $ — ​ $ — ​ $ — Ending Balance: collectively evaluated for impairment ​ $ 4,875 ​ $ 2,010 ​ $ 12,132 ​ $ 1,182 ​ $ 4,940 ​ $ 25,139 Ending Balance: loans acquired with deteriorated credit quality ​ $ — ​ $ — ​ $ — ​ $ — ​ $ — ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Loans: ​ ​ ​ ​ ​ ​ Ending Balance: individually evaluated for impairment ​ $ — ​ $ — ​ $ — ​ $ — ​ $ — ​ $ — Ending Balance: collectively evaluated for impairment ​ $ 626,085 ​ $ 106,194 ​ $ 872,716 ​ $ 80,767 ​ $ 463,902 ​ $ 2,149,664 Ending Balance: loans acquired with deteriorated credit quality ​ $ 1,272 ​ $ 1,278 ​ $ 14,703 ​ $ — ​ $ 4,546 ​ $ 21,799 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (dollars in thousands) Residential ​ Construction Commercial ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2019 Real Estate Real Estate Real Estate Consumer Commercial Total Allowance for loan losses: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Balance, beginning of period ​ $ 3,226 ​ $ 1,097 ​ $ 8,793 ​ $ 902 ​ $ 4,196 ​ $ 18,214 Provision charged to expense ​ ​ 487 ​ ​ 268 ​ ​ 765 ​ ​ 231 ​ ​ 281 ​ ​ 2,032 Losses charged off ​ ​ (30) ​ ​ — ​ ​ (164) ​ ​ (103) ​ ​ (92) ​ ​ (389) Recoveries ​ ​ 23 ​ ​ — ​ ​ 5 ​ ​ 16 ​ ​ 2 ​ ​ 46 Balance, end of period ​ $ 3,706 ​ $ 1,365 ​ $ 9,399 ​ $ 1,046 ​ $ 4,387 ​ $ 19,903 ​ ​ The following table presents the balance in the Allowance for off-balance credit exposure based on portfolio segment as of June 30, 2021, and activity in allowance for the fiscal year ended June 30, 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (dollars in thousands) Residential ​ ​ Construction ​ Commercial ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2021 Real Estate Real Estate Real Estate Consumer Commercial Total Allowance for off-balance sheet credit exposure: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Balance, beginning of period ​ $ 19 ​ $ 769 ​ $ 172 ​ $ 153 ​ $ 846 ​ $ 1,959 Impact of CECL adoption ​ ​ 35 ​ ​ (167) ​ ​ 95 ​ ​ 197 ​ ​ 108 ​ ​ 268 Provision (benefit) charged to expense ​ ​ (17) ​ ​ (100) ​ ​ (79) ​ ​ (132) ​ ​ (94) ​ ​ (422) Balance, end of period ​ $ 37 ​ $ 502 ​ $ 188 ​ $ 218 ​ $ 860 ​ $ 1,805 ​ Included in the Company’s loan portfolio are certain loans acquired in a business combination that have experienced more-than-insignificant deterioration in credit quality since origination, which are considered purchased credit deteriorated (PCD) loans. Prior to the July 1, 2020 adoption of ASU 2016-13, these loans were accounted for in accordance with ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality, and were described as purchased credit impaired (PCI) loans. Under ASC 310-30, these loans were written down at acquisition to an amount estimated to be collectible, and, unless there was further deterioration following the acquisition, an ALLL was not recognized for these loans. As a result, certain historical ratios regarding the Company’s loan portfolio and credit quality cannot be used to compare the Company to peer companies or to compare the Company’s credit quality over time. The ratios particularly affected by accounting under ASC 310-30 include the allowance as a percentage of loans, nonaccrual loans, and nonperforming assets, and nonaccrual loans and nonperforming loans as a percentage of total loans. For more information about the transition from PCI to PCD status of the Company’s acquired loans, see Note 2: Organization and Summary of Significant Accounting Policies Loans Credit Quality Indicators Watch Special Mention Substandard Doubtful Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be Pass A periodic review of selected credits (based on loan size and type) is conducted to identify loans with heightened risk or probable losses and to assign risk grades. The primary responsibility for this review rests with loan administration personnel. This review is supplemented with periodic examinations of both selected credits and the credit review process by the Company’s internal audit function and applicable regulatory agencies. The information from these reviews assists management in the timely identification of problems and potential problems and provides a basis for deciding whether the credit continues to share similar risk characteristics with collectively evaluated loan pools, or whether credit losses for the loan should be evaluated on an individual loan basis. The following table presents the credit risk profile of the Company’s loan portfolio (excluding loans in process and deferred loan fees) based on rating category and year of origination as of June 30, 2021.

Loans that experience insignificant payment delays and payment shortfalls generally are not adversely classified or determined to not share similar risk characteristics with collectively evaluated pools of loans for determination of the ACL estimate. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Significant payment delays or shortfalls may lead to a determination that a loan should be individually evaluated for estimated credit losses.

In an instance where, subsequent to the acquisition, the Company determined it was probable, for a specific loan, that cash flows received would exceed the amount previously expected, the Company will recalculate the amount of accretable yield in order to recognize the improved cash flow expectation as additional interest income over the remaining life of the loan. These loans, however, continued to be reported as impaired loans. In an instance where, subsequent to the acquisition, the Company determined it was probable, for a specific loan, that cash flows received would be less than the amount previously expected, the Company would allocate a specific allowance under the terms of ASC 310-10-35. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (dollars in thousands) ​ Recorded ​ Unpaid Principal ​ Specific June 30, 2020 Balance Balance Allowance Loans without a specific valuation allowance: ​ ​ ​ ​ ​ ​ ​ ​ ​ Residential real estate ​ $ 3,811 ​ $ 4,047 ​ $ — Construction real estate ​ 1,278 ​ 1,312 ​ — Commercial real estate ​ 19,271 ​ 23,676 ​ — Consumer loans ​ ​ — ​ — ​ — Commercial loans ​ 5,040 ​ 6,065 ​ — Loans with a specific valuation allowance: ​ ​ ​ ​ Residential real estate ​ $ — ​ $ — ​ $ — Construction real estate ​ — ​ — ​ — Commercial real estate ​ — ​ — ​ — Consumer loans ​ — ​ — ​ — Commercial loans ​ — ​ — ​ — Total: ​ ​ ​ Residential real estate ​ $ 3,811 ​ $ 4,047 ​ $ — Construction real estate ​ $ 1,278 ​ $ 1,312 ​ $ — Commercial real estate ​ $ 19,271 ​ $ 23,676 ​ $ — Consumer loans ​ $ — ​ $ — ​ $ — Commercial loans ​ $ 5,040 ​ $ 6,065 ​ $ — ​ At June 30, 2020, PCI loans comprised $21.8 million of impaired loans without a specific valuation allowance.

With the adoption of ASU 2016-02, these operating leases are now included as a ROU asset in the premises and equipment line item on the Company’s consolidated balance sheets. The corresponding lease liability is included in the accounts payable and other liabilities line item on the Company’s consolidated balance sheets. Because these leases are classified as operating leases, the adoption of the new standard did not have a material effect on lease expense on the Company’s consolidated statements of income. ASU 2016-02 also requires certain other accounting elections. The Company elected the short-term lease recognition exemption for all leases that qualify, meaning those with terms under twelve months. ROU assets or lease liabilities are not to be recognized for short-term leases. The calculated amount of the ROU assets and lease liabilities in the table below are impacted by the length of the lease term and the discount rate used to present value the minimum lease payments. The Company’s lease agreements often include one or more options to renew at the Company’s discretion. If at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the ROU asset and lease liability. Regarding the discount rate, the ASU 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 over a similar term. The discount rate utilized was 5%. The expected lease terms range from 18 months to 21 years. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ At or For the ​ At or For the ​ ​ Twelve Months Ended ​ Twelve Months Ended ​ ​ June 30, 2021 ​ June 30, 2020 Consolidated Balance Sheet ​ ​ ​ ​ ​ ​ Operating leases right of use asset ​ $ 2,770 ​ $ 1,965 Operating leases liability ​ $ 2,770 ​ $ 1,965 ​ ​ ​ ​ ​ ​ ​ Consolidated Statement of Income ​ ​ ​ ​ ​ ​ Operating lease costs classified as occupancy and equipment expense ​ $ 340 ​ $ 214 (includes short-term lease costs) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Supplemental disclosures of cash flow information ​ ​ ​ ​ ​ ​ Cash paid for amounts included in the measurement of lease liabilities: ​ ​ ​ ​ ​ ​ Operating cash flows from operating leases ​ $ 282 ​ $ 174 ROU assets obtained in exchange for operating lease obligations: ​ $ 804 ​ $ 2,004 ​ For the years ended June 30, 2021 and 2020, lease expense was $340,000 and $214,000, respectively.

Stockholders' Equity and Regulatory Capital
Stockholders' Equity and Regulatory Capital	NOTE 11: Stockholders’ Equity and Regulatory Capital The Company and Bank are subject to various regulatory capital requirements administered by the Federal banking agencies. Failure to meet minimum capital requirements can result in certain mandatory—and possibly additional discretionary – actions by regulators that, if undertaken, could have a direct material effect on the Company’s 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 and the Bank’s assets, liabilities, and certain off-balance sheet items as calculated under U.S. GAAP, regulatory reporting requirements and regulatory capital standards. The Company and Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Furthermore, the Company and Bank’s regulators could require adjustments to regulatory capital not reflected in the condensed consolidated financial statements. Quantitative measures established by regulatory capital standards to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the table below) of total capital, Tier 1 capital (as defined), and common equity Tier 1 capital (as defined) to risk-weighted assets (as defined) and of Tier 1 capital (as defined) to average total assets (as defined). Additionally, to make distributions or discretionary bonus payments, the Company and Bank must maintain a capital conservation buffer of 2.5% of risk-weighted assets. Management believes, as of June 30, 2021 and 2020, that the Company and the Bank met all capital adequacy requirements to which they are subject. Effective January 1, 2020, depository institutions and depository institution holding companies that have less than $10 billion in total consolidated assets and meet other qualifying criteria, including a tier 1 leverage ratio of greater than 9 percent, are considered qualifying community banking organizations and are eligible to opt into an alternative, simplified regulatory capital framework, which utilizes a newly-defined “Community Bank Leverage Ratio” (CBLR). The CBLR framework is an optional framework that is designed to reduce burden by removing the requirements for calculating and reporting risk-based capital ratios for qualifying community banking organizations that opt into the framework. Qualifying community banking organizations that elect to use the CBLR framework and that maintain a leverage ratio of greater than 9 percent are considered to have satisfied the risk-based and leverage capital requirements in the agencies’ generally applicable capital rule. In April 2020, the federal bank regulatory agencies announced the issuance of two interim final rules to provide temporary relief to community banking organizations. Under the rules, CBLR requirement was a minimum of 8% for the remainder of calendar year 2020, and is 8.5% for calendar year 2021, and 9% thereafter. The Company and the Bank have not made an election to utilize the CBLR framework, but will continue to monitor the available option, and could do so in the future. In August 2020, the Federal banking agencies adopted a final rule updating a December 2018 rule regarding the impact on regulatory capital of adoption of the CECL standard. The rule now allows institutions that adopt the CECL standard in 2020 a five-year transition period to recognize the estimated impact of adoption on regulatory capital. The Company and the Bank elected to exercise the option to recognize the impact of adoption over the five-year period. As of June 30, 2021, the most recent notification from the Federal banking agencies 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. There are no conditions or events since that notification that management believes have changed the Bank’s category.

Commitments and Credit Risk
Commitments and Credit Risk	NOTE 12: Commitments and Credit Risk Standby Letters of Credit Standby letters of credit are irrevocable conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Financial standby letters of credit are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing and similar transactions. Performance standby letters of credit are issued to guarantee performance of certain customers under non-financial contractual obligations. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loans to customers. The Company had total outstanding standby letters of credit amounting to $4.0 million at June 30, 2021, and $3.2 million at June 30, 2020, with terms ranging from 12 to 24 months . At June 30, 2021, the Company’s deferred revenue under standby letters of credit agreements was nominal. Off-balance-sheet and Credit Risk These financial instruments include commitments to extend credit. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the balance sheets. Lines of credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Lines of credit generally have fixed expiration dates. Since a portion of the line may expire without being drawn upon, the total unused lines do not necessarily represent future cash requirements. Each customer’s creditworthiness is evaluated on a case-by-case basis. The amount of collateral obtained, if deemed necessary, is based on management’s credit evaluation of the counterparty. Collateral held varies but may include accounts receivable, inventory, property, plant and equipment, commercial real estate and residential real estate. Management uses the same credit policies in granting lines of credit as it does for on balance sheet instruments. The Company had $491.6 million in commitments to extend credit at June 30, 2021, and $416.2 million at June 30, 2020. At June 30, 2021, total commitments to originate fixed-rate loans with terms in excess of one year were $134.5 million at rates ranging from 2.25% to 5.50%, with a weighted-average rate of 4.04%. Commitments to extend credit and standby letters of credit include exposure to some credit loss in the event of nonperformance of the customer. The Company’s policies for credit commitments and financial guarantees are the same as those for extension of credit that are recorded in the balance sheet. The commitments extend over varying periods of time with the majority being disbursed within a thirty-day period. The Company originates collateralized commercial, real estate, and consumer loans to customers in Missouri, Arkansas, and Illinois. Although the Company has a diversified portfolio, loans aggregating $801.6 million at June 30, 2021, are secured by single and multi-family residential real estate generally located in the Company’s primary lending area.

Acquisitions	NOTE 14: Acquisitions On May 22, 2020 the Company completed its acquisition of Central Federal Bancshares, Inc. (“Central”), and its wholly owned subsidiary, Central Federal Savings and Loan Association (“Central Federal”), in an all-cash transaction valued at approximately $21.9 million. Net cash paid for the acquisition totaled approximately $9.1 million. The conversion of data systems took place on June 7, 2020. The Company incurred $1.2 million of third-party acquisition-related costs with $1.2 million being included in noninterest expense in the Company’s consolidated statement of income for the year ended June 30, 2020. Under the acquisition method of accounting, the total purchase price is allocated to net tangible and intangible assets based on their current estimated fair values on the date of the acquisition. Based on valuations of the fair value of tangible and intangible assets acquired and liabilities assumed, the purchase price for the Central acquisition is detailed in the following table. ​ ​ ​ ​ ​ Central Federal Bancshares ​ ​ Fair Value of Consideration Transferred ​ ​ ​ (dollars in thousands) ​ ​ ​ Cash ​ $ 21,942 ​ ​ ​ ​ ​ ​ ​ ​ Recognized amounts of identifiable assets acquired and liabilities assumed ​ ​ ​ ​ ​ ​ Cash and cash equivalents ​ $ 12,862 Investment securities ​ ​ 4,355 Loans ​ ​ 51,449 Premises and equipment ​ ​ 723 Identifiable intangible assets ​ ​ 540 Miscellaneous other assets ​ ​ 639 ​ ​ ​ ​ Deposits ​ ​ (46,720) Miscellaneous other liabilities ​ ​ (1,783) Total identifiable net assets ​ ​ 22,065 Bargain Purchase Gain ​ $ (123) ​ Of the total purchase price of $21.9 million, $540,000 has been allocated to core deposit intangible. None of the purchase price was allocated to goodwill, as the acquisition resulted in a bargain purchase gain of $123,000. The core deposit intangible will be amortized over six years on a straight line basis. The Company acquired the $52.1 million loan portfolio at an estimated fair value discount of $662,000. The excess of expected cash flows above the fair value of the performing portion of loans will be accreted to interest income over the remaining lives of the loans in accordance with ASC 310-30. Management identified no purchased credit-impaired loans associated with the Central acquisition (ASC 310-30). ​ ​

Organization and Summary of Significant Accounting Policies
Organization	Organization. The Bank is primarily engaged in providing a full range of banking and financial services to individuals and corporate customers in its market areas. The Bank and Company are subject to competition from other financial institutions. The Bank and Company are subject to the regulation of certain federal and state agencies and undergo periodic examinations by those regulatory authorities.
Basis of Financial Statement Presentation	Basis of Financial Statement Presentation.
Principles of Consolidation	Principles of Consolidation.
Use of Estimates	Use of Estimates. On July 1, 2020, Financial Instruments – Credit Losses which created material changes to the existing critical accounting policy that existed at June 30, 2020 . Effective July 1, 2020 , the significant accounting policy which was considered to be the most critical in preparing the Company’s consolidated financial statements is the determination of the allowance for credit losses (“ACL”) on loans. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for credit losses, and estimated fair values of purchased loans.
Cash and Cash Equivalents	Cash and Cash Equivalents.
Interest-bearing Time Deposits	Interest-bearing Time Deposits.
Available for Sale Securities	Available for Sale Securities. Premiums and discounts on debt securities are amortized or accreted as adjustments to income over the estimated life of the security using the level yield method. Realized gains or losses on the sale of securities is based on the specific identification method. The fair value of securities is based on quoted market prices or dealer quotes. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities. The Company does not invest in collateralized mortgage obligations that are considered high risk. For AFS securities with fair value less than amortized cost that management has no intent to sell and believes that it more likely than not will not be required to sell prior to recovery, only the credit loss component of the impairment is recognized in earnings, while the noncredit loss is recognized in accumulated other comprehensive income (loss). The credit loss component recognized in earnings is identified as the amount of principal cash flows not expected to be received over the remaining term of the security as projected based on cash flow projections, and is recorded to the ACL, by a charge to provision for credit losses. Accrued interest receivable is excluded from the estimate of credit losses. Both the ACL and the adjustment to net income may be reversed if conditions change. However, if the Company intends to sell an impaired AFS security, or, if it is more likely than not the Company will be required to sell such a security before recovering its amortized cost basis, the entire impairment amount would be recognized in earnings with a corresponding adjustment to the security’s amortized cost basis. Because the security’s amortized cost basis is adjusted to fair value, there is no ACL in this situation. At adoption of ASU 2016-13, no impairment on AFS securities was attributable to credit. The Company will evaluate impaired AFS securities at the individual level on a quarterly basis, and will consider such factors including, but not limited to: the extent to which the fair value of the security is less than the amortized cost basis; adverse conditions specifically related to the security, an industry, or geographic area; the payment structure of the security and likelihood of the issuer to be able to make payments that may increase in the future; failure of the issuer to make scheduled interest or principal payments; any changes to the rating of the security by a rating agency; and the ability and intent to hold the security until maturity. A qualitative determination as to whether any portion of the impairment is attributable to credit risk is acceptable. There were no credit related factors underlying unrealized losses on AFS securities at June 30, 2021, and June 30, 2020. Changes in the ACL are recorded as expense. Losses are charged against the ACL when management believes the uncollectability of an AFS debt security is confirmed or when either of the criteria regarding intent or requirement to sell is met.
Federal Reserve Bank and Federal Home Loan Bank Stock	Federal Reserve Bank and Federal Home Loan Bank Stock.
Loans	Loans. Interest on loans is accrued based upon the principal amount outstanding. The accrual of interest on loans is discontinued when, in management’s judgment, the collectability of interest or principal in the normal course of business is doubtful. The Company complies with regulatory guidance which indicates that loans should be placed in nonaccrual status when 90 days past due, unless the loan is both well-secured and in the process of collection. A loan that is “in the process of collection” may be subject to legal action or, in appropriate circumstances, through other collection efforts reasonably expected to result in repayment or restoration to current status in the near future. A loan is considered delinquent when a payment has not been made by the contractual due date. At June 30, 2021, some loans were modified under the terms of the Coronavirus Aid, Relief and Economic Security Act (the CARES Act), which provides that loans modified after March 1, 2020, due to the COVID-19 pandemic, and which were otherwise current at December 31, 2019, need not be accounted for as troubled debt restructurings (TDRs). While these loans may not have met the contractual due dates of payments under their previous terms, so long as they were compliant with the terms of the modification made under the CARES Act, they would not have been reported as delinquent at June 30, 2020 or June 30, 2021. See further disclosure in Note 3: Loans and Allowance for Loan Losses. Interest income previously accrued but not collected at the date a loan is placed on nonaccrual status is reversed against interest income. Cash receipts on a nonaccrual loan are applied to principal and interest in accordance with its contractual terms unless full payment of principal is not expected, in which case cash receipts, whether designated as principal or interest, are applied as a reduction of the carrying value of the loan. A nonaccrual loan is generally returned to accrual status when principal and interest payments are current, full collectability of principal and interest is reasonably assured, and a consistent record of performance has been demonstrated. The ACL is a valuation account that is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on the loans, and is established through provision for credit losses charged to current earnings. The ACL is increased by the provision for losses on loans charged to expense and reduced by loans charged off, net of recoveries. Loans are charged off in the period deemed uncollectible, based on management’s analysis of expected cash flows (for non-collateral dependent loans) or collateral value (for collateral-dependent loans). Subsequent recoveries of loans previously charged off, if any, are credited to the allowance when received. Management estimates the ACL using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Adjustments may be made to historical loss information for differences identified in current loan-specific risk characteristics, such as differences in underwriting standards or terms; lending review systems; experience, ability, or depth of lending management and staff; portfolio growth and mix; delinquency levels and trends; as well as for changes in environmental conditions, such as changes in economic activity or employment, agricultural economic conditions, property values, or other relevant factors. The Company generally incorporates a reasonable and supportable forecast period of four quarters, and a four-quarter, straight-line reversion period to return to long-term historical averages. The ACL is measured on a collective (pool) basis when similar risk characteristics exist. For loans that do not share general risk characteristics with the collectively evaluated pools, the Company estimates credit losses on an individual loan basis, and these loans are excluded from the collectively evaluated pools. An ACL for an individually evaluated loan is recorded when the amortized cost basis of the loan exceeds the discounted estimated cash flows using the loan’s initial effective interest rate or the fair value, less estimated costs to sell, of the collateral for certain collateral dependent loans. For the collectively evaluated pools, the Company segments the loan portfolio primarily by loan purpose and collateral into 24 pools, which are homogeneous groups of loans that possess similar loss potential characteristics. The Company primarily utilizes the discounted cash flow (“DCF”) methodology for measurement of the required ACL. For a limited number of pools with a relatively small balance of unpaid principal balance, the Company utilized the remaining life method. The DCF model implements probability of default (“PD”) and loss given default (“LGD”) calculations at the instrument level. PD and LGD are determined based on statistical analysis and correlation of historical losses with various economic factors over time. In general, the Company’s losses have not correlated well with economic factors, and the Company has utilized peer data where more appropriate. The Company defines a default as an event of charge off, an adverse (substandard or worse) internal credit rating, becoming delinquent 90 days or more, or being placed on nonaccrual status. A PD/LGD estimate is applied to a projected model of the loan’s cashflow, including principal and interest payments, with consideration for prepayment speeds, principal curtailments, and recovery lag. Prior to the July 1, 2020, adoption of ASU 2016-13, the allowance for loan and lease losses (ALLL) represented management’s best estimate of probable losses in the existing loan portfolio at the end of the reporting period. Integral to the methodology for determining the adequacy of the ALLL was portfolio segmentation and impairment measurement. Under the Company’s methodology, loans were first segmented into 1) those comprising large groups of homogeneous loans which are collectively evaluated for impairment and 2) all other loans which are individually evaluated. Those loans in the second category were further segmented utilizing a defined grading system which involves categorizing loans by severity of risk based on conditions that may affect the ability of the borrowers to repay their debt, such as current financial information, collateral valuations, historical payment experience, credit documentation, public information, and current trends. Loans were considered impaired if, based on current information and events, it was considered probable that the Company would be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement, and was generally based on the fair value, less estimated costs to sell, of the loan’s collateral. If the loan was not collateral-dependent, the measurement of impairment was based on the present value of expected future cash flows discounted at the historical effective interest rate, or the observable market price of the loan. Impairment identified through this evaluation process was a component of the ALLL. If a loan was not considered impaired, it was grouped together with loans having similar characteristics (i.e., the same risk grade), and an ALLL was based upon a quantitative factor (historical average charge-offs) and qualitative factors such as changes in lending policies; national, regional, and local economic conditions; changes in mix and volume of portfolio; experience, ability, and depth of lending management and staff; entry to new markets; levels and trends of delinquent, nonaccrual, special mention, and classified loans; concentrations of credit; changes in collateral values; agricultural economic conditions; and regulatory risk. Prior to the July 1, 2020, adoption of ASU 2016-13, loans acquired in an acquisition that had evidence of credit quality deterioration since origination and for which it was probable that the Company would be unable to collect all contractually required payments receivable were considered purchased credit impaired (“PCI”). PCI loans were individually evaluated and recorded at fair value at the date of acquisition with no initial ALLL based on a DCF methodology that considered various factors including the type of loan and related collateral, classification status, fixed or variable interest rate, term of loan and whether or not the loan was amortizing, and a discount rate reflecting the Company’s assessment of risk inherent in the cash flow estimates. The difference between the DCFs expected at acquisition and the investment in the loan, or the “accretable yield,” was recognized as interest income on a level-yield method over the life of the loan. Contractually required payments for interest and principal that exceed the DCFs expected at acquisition, or the “non-accretable difference,” were not recognized on the balance sheet and did not result in any yield adjustments, loss accruals or valuation allowances. Increases in expected cash flows, including prepayments, subsequent to the initial investment were recognized prospectively through adjustment of the yield on the loan over its remaining life. Decreases in expected cash flows were recognized as impairment. ALLL on PCI loans reflected only losses incurred after the acquisition (meaning the present value of all cash flows expected at acquisition that ultimately were not to be received). Subsequent to the July 1, 2020, adoption of ASU 2016-13, loans acquired in a business combination that have experienced more-than-insignificant deterioration in credit quality since origination are considered purchased credit deteriorated (“PCD”) loans. At the acquisition date, an estimate of expected credit losses is made for groups of PCD loans with similar risk characteristics and individual PCD loans without similar risk characteristics. This initial ACL is allocated to individual PCD loans and added to the purchase price or acquisition date fair values to establish the initial amortized cost basis of the PCD loans. As the initial ACL is added to the purchase price, there is no credit loss expense recognized upon acquisition of a PCD loan. Any difference between the unpaid principal balance of PCD loans and the amortized cost basis is considered to relate to non-credit factors and results in a discount or premium. Discounts and premiums are recognized through interest income on a level-yield method over the life of the loans. Upon adoption of ASU 2016-13, the amortized cost basis of the PCD assets were adjusted to reflect the addition of $434,000 to the ACL. The remaining noncredit discount, based on the adjusted amortized cost basis, will be accreted into interest income at the effective interest rate as of July 1, 2020. Loan fees and certain direct loan origination costs are deferred, and the net fee or cost is recognized as an adjustment to interest income using the interest method over the contractual life of the loans.
Off-Balance Sheet Credit Exposures	Off-Balance Sheet Credit Exposures. Off-balance sheet credit instruments include commitments to make loans, and commercial letters of credit, issued to meet customer financing needs. The Company’s exposure to credit loss in the event of non-performance by the other party to the financial instrument for off-balance sheet loan commitments is represented by the contractual amount of those instruments. Such financial instruments are recorded when they are funded. The ACL on off-balance sheet credit exposures is estimated by loan pool on a quarterly basis under the current CECL model using the same methodologies as portfolio loans, taking into consideration the likelihood that funding will occur and is included in other liabilities on the Company’s consolidated balance sheets. The Company records an ACL on off-balance sheet credit exposures, unless the commitments to extend credit are unconditionally cancelable. In prior periods the charge for credit loss expense for off-balance sheet credit exposures was included in other non-interest expense in the Company’s consolidated statements of income, whereas under updated regulatory accounting guidelines, that figure is combined with the provision for credit losses beginning July 1, 2020.
Foreclosed Real Estate	Foreclosed Real Estate. Valuations are periodically performed by management, and an allowance for losses is established by a charge to operations if the carrying value of a property exceeds its estimated fair value, less estimated selling costs. Loans to facilitate the sale of real estate acquired in foreclosure are discounted if made at less than market rates. Discounts are amortized over the fixed interest period of each loan using the interest method.

Income Taxes	Income Taxes. the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Company determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more likely than not means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to the management’s judgment. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. The Company recognizes interest and penalties on income taxes as a component of income tax expense. The Company files consolidated income tax returns with its subsidiaries, the Bank and SB Real Estate Investments, LLC, with a tax year ended June 30. Southern Bank Real Estate Investments, LLC files a separate REIT return for federal tax purposes, and also files state income tax returns with a tax year ended December 31.
Incentive Plan	Incentive Plans. The Company accounts for its Equity Incentive Plan (EIP), and Omnibus Incentive Plan (OIP) in accordance with ASC 718, “Share-Based Payment.” Compensation expense is based on the market price of the Company’s stock on the date the shares are granted and is recorded over the vesting period. The difference between the grant-date fair value and the fair value on the date the shares are considered earned represents a tax benefit to the Company that is recorded as an adjustment to income tax expense.

New Accounting Pronouncements	The following paragraphs summarize the impact of new accounting pronouncements: In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) - Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 modifies the disclosure requirements on fair value measurements in Topic 820. The amendments in this update remove disclosures that no longer are considered cost beneficial, modify/clarify the specific requirements of certain disclosures, and add disclosure requirements identified as relevant. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, with early adoption permitted for certain removed and modified disclosures. Adoption of this standard did not have a significant impact on the Company’s consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326), which the Company adopted July 1, 2020. The Update amended guidance on reporting credit losses for financial assets held at amortized cost basis and available for sale debt securities. For financial assets held at amortized cost basis, Topic 326 eliminated the probable initial recognition threshold in current GAAP and, instead, requires an entity to reflect its current estimate of all expected credit losses. The Update affects loans, debt securities, trade receivables, net investments in leases, off balance sheet credit exposures, and any other financial assets not excluded from the scope that have the contractual right to receive cash. Adoption was applied on a modified retrospective basis, through a cumulative-effect adjustment to retained earnings. Adoption resulted in an increase to the ACL of $8.9 million, related to the transition from the incurred loss model to the CECL ACL model, and an increase of $434,000 related to the transition from PCI to PCD methodology, relative to the ALLL as of June 30, 2020. The Company also recorded an adjustment to the reserve for unfunded commitments recorded in other liabilities of $268,000. The impact at adoption was reflected as an adjustment to beginning retained earnings, net of income taxes, in the amount of $7.2 million. In accordance with the new standard, management did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption. The adoption of ASU 2016-13 in fiscal 2021 could also impact the Company’s future earnings, perhaps materially The following table illustrates the impact of adoption of ASU 2016-13: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ July 1, 2020 ​ As reported As reported Impact of ​ under prior to adoption (dollars in thousands) ASU 2016-13 ASU 2016-13 ASU 2016-13 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Loans receivable ​ $ 2,142,363 ​ $ 2,141,929 ​ $ 434 Allowance for credit losses on loans: ​ ​ ​ ​ ​ ​ ​ ​ ​ Real Estate Loans: ​ ​ ​ ​ ​ ​ ​ ​ ​ Residential ​ 8,396 ​ 4,875 ​ 3,521 Construction ​ 1,889 ​ 2,010 ​ (121) Commercial ​ 15,988 ​ 12,132 ​ 3,856 Consumer loans ​ 2,247 ​ 1,182 ​ 1,065 Commercial loans ​ 5,952 ​ 4,940 ​ 1,012 Total allowance for credit losses on loans ​ $ 34,472 ​ $ 25,139 ​ $ 9,333 Total allowance for credit losses on off-balance sheet credit exposures ​ $ 2,227 ​ $ 1,959 ​ $ 268 ​ The above table includes the impact of ASU 2016-13 adoption for PCD assets previously classified as PCI. The change in the ACL includes $434,000 attributable to residential and commercial real estate loans, and the amortized cost basis of loans receivable was increased for those loans by that total amount. In March 2020, the CARES Act was signed into law, creating a forbearance program for federally backed mortgage loans, protects borrowers from negative credit reporting due to loan accommodations related to the National Emergency, and provides financial institutions the option to temporarily suspend certain requirements under U.S. GAAP related to troubled debt restructurings (TDR) for a limited period of time to account for the effects of COVID-19. The Company has elected to not apply ASC Subtopic 310-40 for loans eligible under the CARES Act, based on the modification’s (1) relation to COVID-19, (2) execution for a loan that was not more than 30-days past due as of December 31, 2019, and (3) execution between March 1, 2020, and the earlier of the date that falls 60 days following the termination of the declared National Emergency, or December 31, 2020. The 2021 Consolidated Appropriations Act, signed into law in December 2020, extended the window during which loans may be modified without classification as TDRs under ASC Subtopic 310-40, to the earlier of January 1, 2022, or 60 days following the termination of the declared National Emergency.
Repurchase Agreements	The carrying value of investment and mortgage-backed securities pledged as collateral to secure public deposits and securities sold under agreements to repurchase amounted to $155.6 million and $156.1 million at June 30, 2021 and 2020, respectively. The securities pledged consist of marketable securities, including $95.4 million and $82.0 million of Mortgage-Backed Securities, $18.8 million and $41.9 million of Collateralized Mortgage Obligations, $41.4 million and $32.0 million of State and Political Subdivisions Obligations, and $0 and $200,000 of Other Securities at June 30, 2021 and 2020, respectively.

At June 30, 2021, unvested compensation expense related to the EIP was approximately $51,000. 2003 Stock Option Plan As of June 30, 2021, there was no remaining unrecognized compensation expense related to unvested stock options under the 2003 Plan. The aggregate intrinsic value of stock options outstanding, all of which were exercisable, at June 30, 2021, was $274,000. During fiscal 2020, options to purchase 10,000 shares were exercised; no options to purchase shares were exercised in fiscal 2021 or 2019. The intrinsic value of options vested in fiscal 2020 and 2019 was $14,000, and $35,000, respectively, and no options vested in fiscal 2021. 2017 Omnibus Incentive Plan Under the 2017 Plan, options to purchase 79,500 shares have been issued Full value awards totaling 18,925, 15,525, and 15,000 shares, respectively, were issued to employees and directors in fiscal 2021, 2020, and 2019. All full value awards were in the form of either restricted stock vesting at the rate of 20% of such shares per year, or performance-based restricted stock vesting at up to 20% of such shares per year, contingent on the achievement of specified profitability targets over a three-year period. During fiscal 2021, 2020, and 2019, full value awards of 9,770, 7,080 and 4,200 shares were vested, respectively. Compensation expense, in the amount of the fair market value of the common stock at the date of grant, is recognized pro-rata over the five years during which the shares vest. Compensation expense for full value awards under the 2017 Plan for fiscal 2021, 2020, and 2019 was $351,000, $293,000, and $189,000, respectively. At June 30, 2021, unvested compensation expense related to full value awards under the 2017 Plan was approximately $1.5 million. Changes in options outstanding under the 2003 Plan and the 2017 Plan were as follows:
Regulatory Capital Requirements	The Company and Bank are subject to various regulatory capital requirements administered by the Federal banking agencies. Failure to meet minimum capital requirements can result in certain mandatory—and possibly additional discretionary – actions by regulators that, if undertaken, could have a direct material effect on the Company’s 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 and the Bank’s assets, liabilities, and certain off-balance sheet items as calculated under U.S. GAAP, regulatory reporting requirements and regulatory capital standards. The Company and Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Furthermore, the Company and Bank’s regulators could require adjustments to regulatory capital not reflected in the condensed consolidated financial statements. Quantitative measures established by regulatory capital standards to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the table below) of total capital, Tier 1 capital (as defined), and common equity Tier 1 capital (as defined) to risk-weighted assets (as defined) and of Tier 1 capital (as defined) to average total assets (as defined). Additionally, to make distributions or discretionary bonus payments, the Company and Bank must maintain a capital conservation buffer of 2.5% of risk-weighted assets. Management believes, as of June 30, 2021 and 2020, that the Company and the Bank met all capital adequacy requirements to which they are subject. Effective January 1, 2020, depository institutions and depository institution holding companies that have less than $10 billion in total consolidated assets and meet other qualifying criteria, including a tier 1 leverage ratio of greater than 9 percent, are considered qualifying community banking organizations and are eligible to opt into an alternative, simplified regulatory capital framework, which utilizes a newly-defined “Community Bank Leverage Ratio” (CBLR). The CBLR framework is an optional framework that is designed to reduce burden by removing the requirements for calculating and reporting risk-based capital ratios for qualifying community banking organizations that opt into the framework. Qualifying community banking organizations that elect to use the CBLR framework and that maintain a leverage ratio of greater than 9 percent are considered to have satisfied the risk-based and leverage capital requirements in the agencies’ generally applicable capital rule. In April 2020, the federal bank regulatory agencies announced the issuance of two interim final rules to provide temporary relief to community banking organizations. Under the rules, CBLR requirement was a minimum of 8% for the remainder of calendar year 2020, and is 8.5% for calendar year 2021, and 9% thereafter. The Company and the Bank have not made an election to utilize the CBLR framework, but will continue to monitor the available option, and could do so in the future. In August 2020, the Federal banking agencies adopted a final rule updating a December 2018 rule regarding the impact on regulatory capital of adoption of the CECL standard. The rule now allows institutions that adopt the CECL standard in 2020 a five-year transition period to recognize the estimated impact of adoption on regulatory capital. The Company and the Bank elected to exercise the option to recognize the impact of adoption over the five-year period. As of June 30, 2021, the most recent notification from the Federal banking agencies 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. There are no conditions or events since that notification that management believes have changed the Bank’s category.
Standby Letters of Credit	Standby Letters of Credit Standby letters of credit are irrevocable conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Financial standby letters of credit are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing and similar transactions. Performance standby letters of credit are issued to guarantee performance of certain customers under non-financial contractual obligations. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loans to customers. The Company had total outstanding standby letters of credit amounting to $4.0 million at June 30, 2021, and $3.2 million at June 30, 2020, with terms ranging from 12 to 24 months . At June 30, 2021, the Company’s deferred revenue under standby letters of credit agreements was nominal.
Accounting Principles	Accounting principles generally accepted in the United States of America require disclosure of certain significant estimates and current vulnerabilities due to certain concentrations. Estimates related to the allowance for loan losses are described in Note 1.
