Organization and Summary of Significant Accounting Policies |
Organization | Organization. Southern Missouri Bancorp, Inc., a Missouri corporation (the Company) was organized in 1994 and is the parent company of Southern Bank (the Bank). Substantially all of the Company’s consolidated revenues are derived from the operations of the Bank, and the Bank represents substantially all of the Company’s consolidated assets and liabilities. SB Real Estate Investments, LLC is a wholly-owned subsidiary of the Bank formed to hold Southern Bank Real Estate Investments, LLC. Southern Bank Real Estate Investments, LLC is a real estate investment trust (REIT) which is controlled by SB Real Estate Investments, LLC, and has other preferred shareholders in order to meet the requirements to be a REIT. At March 31, 2024, assets of the REIT were approximately $1.4 billion, and consisted primarily of real estate loan participations acquired from the Bank. 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. The condensed consolidated financial statements of the Company have been prepared in conformity with accounting principles generally accepted in the United States of America and general practices within the banking industry. In the normal course of business, the Company encounters two significant types of risk: economic and regulatory. Economic risk is comprised of interest rate risk, credit risk, and market risk. The Company is subject to interest rate risk to the degree that its interest-bearing liabilities reprice on a different basis than its interest-earning assets. Credit risk is the risk of default on the Company’s investment or loan portfolios resulting from the borrowers’ inability or unwillingness to make contractually required payments. Market risk reflects changes in the value of the investment portfolio, collateral underlying loans receivable, and the value of the Company’s investments in real estate.
Principles of Consolidation | Principles of Consolidation. The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.
Use of Estimates | Use of Estimates. The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for credit losses, estimated fair values of purchased loans, and certain other assumptions and judgmental factors relating to investment securities.
Cash and Cash Equivalents | Cash and Cash Equivalents. For purposes of reporting cash flows, cash and cash equivalents includes cash, due from depository institutions and interest-bearing deposits in other depository institutions with original maturities of three months or less. Interest-bearing deposits in other depository institutions were $112.5 million and $3.8 million at March 31, 2024 and June 30, 2023, respectively. The deposits are held in various commercial banks with a total of $1.8 million and $1.3 million exceeding the FDIC’s deposit insurance limits at March 31, 2024 and June 30, 2023, respectively, as well as at the Federal Reserve and the Federal Home Loan Banks of Des Moines and Chicago.
Interest-bearing Time Deposits | Interest-bearing Time Deposits. Interest bearing time deposits in banks mature within three years and are carried at cost.
Available for Sale Securities | Available for Sale Securities. Available for sale securities (“AFS”), which include any security for which the Company has no immediate plan to sell but which may be sold in the future, are carried at fair value. Unrealized gains and losses, net of tax, are reported in accumulated other comprehensive loss, a component of stockholders’ equity. All securities have been classified as available for sale. 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 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 Allowance for Credit Losses (“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. The Company evaluates impaired AFS securities at the individual level on a quarterly basis, and considers 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 March 31, 2024, or June 30, 2023. 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. The Bank is a member of the Federal Reserve and the Federal Home Loan Bank (“FHLB”) systems. Capital stock of the Federal Reserve and the FHLB is a required investment of the Bank based upon a predetermined formula and is carried at cost.
Loans | Loans. Loans are generally stated at unpaid principal balances, less the ACL, any net deferred loan origination fees, and unamortized premiums or discounts on purchased 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. 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 a provision for credit losses (“PCL”) charged to current earnings. The ACL is increased by the provision for credit 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, the Company utilizes 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 to include 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. 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. 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.
Foreclosed Real Estate | Foreclosed Real Estate. Real estate acquired by foreclosure or by deed in lieu of foreclosure is initially recorded at fair value less estimated selling costs, establishing a new cost basis. Any costs for development and improvement of the property that are warranted are capitalized. 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 | Premises and Equipment. Premises and equipment are stated at cost less accumulated depreciation and include expenditures for major betterments and renewals. Maintenance, repairs, and minor renewals are expensed as incurred. When property is retired or sold, the retired asset and related accumulated depreciation are removed from the accounts and the resulting gain or loss taken into income. The Company reviews property and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If such assets are considered to be impaired, the impairment loss recognized is measured by the amount by which the carrying amount exceeds the fair value of the assets. Depreciation is computed by use of straight-line and accelerated methods over the estimated useful lives of the assets. Estimated lives are generally seven to forty years for premises, three to seven years for equipment, and three years for software.
Bank Owned Life Insurance | Bank Owned Life Insurance. Bank owned life insurance policies are reflected in the condensed consolidated balance sheets at the estimated cash surrender value. Changes in the cash surrender value of these policies, as well as a portion of the insurance proceeds received, are recorded in noninterest income in the condensed consolidated statements of income.
Goodwill | Goodwill. The Company’s goodwill is evaluated annually for impairment or more frequently if impairment indicators are present. A qualitative assessment is performed to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value is less than the carrying amount, including goodwill. If, based on the evaluation, it is determined to be more likely than not that the fair value is less than the carrying value, then goodwill is tested further for impairment. If the implied fair value of goodwill is lower than its carrying amount, a goodwill impairment is indicated and goodwill is written down to its implied fair value. Subsequent increases in goodwill value are not recognized in the financial statements. As of June 30, 2023, there was no impairment indicated, based on a qualitative assessment of goodwill, which considered: the market value of the Company’s common stock; concentrations of credit; profitability; nonperforming assets; capital levels; and results of recent regulatory examinations. There was no impairment of goodwill at March 31, 2024.
Intangible Assets | Intangible Assets. The Company’s intangible assets at March 31, 2024 included gross core deposit intangibles of $39.1 million with $16.9 million accumulated amortization, gross other identifiable intangibles of $6.4 million with accumulated amortization of $4.1 million, and mortgage and SBA servicing rights of $2.8 million. At June 30, 2023, the Company’s intangible assets included gross core deposit intangibles of $39.1 million with $14.0 million accumulated amortization, gross other identifiable intangibles of $6.4 million with accumulated amortization of $3.9 million, and mortgage and SBA servicing rights of $2.9 million. The Company’s core deposit and other intangible assets are being amortized using the straight line method, in accordance with ASC 350, over periods ranging from five to ten years, with amortization expense expected to be approximately $1.0 million in the remainder of fiscal 2024, $3.5 million in fiscal 2025, $3.0 million in fiscal 2026, $2.7 million in fiscal 2027, $2.7 million in fiscal 2028, and $11.5 million thereafter. As of June 30, 2023, there was no impairment indicated, and there was no impairment of other intangible assets at March 31, 2024.
Income Taxes | Income Taxes. The Company accounts for income taxes in accordance with income tax accounting guidance (ASC 740, Income Taxes). The income tax accounting guidance results in two components of income tax expense: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying 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 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, if any, 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 | 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.
Non-Employee Directors' Retirement | Non-Employee Directors’ Retirement. The Bank entered into directors’ retirement agreements beginning in April 1994 for non-employee directors and continued to do so for new non-employee directors joining the Bank’s board through December 2014. These directors’ retirement agreements provide that each participating non-employee director (participant) shall receive, upon termination of service on the Board on or after age 60, other than termination for cause, a benefit in equal annual installments over a five year period. The benefit will be based upon the product of the participant’s vesting percentage and the total Board fees paid to the participant during the calendar year preceding termination of service on the Board. The vesting percentage shall be determined based upon the participant’s years of service on the Board. In the event that the participant dies before collecting any or all of the benefits, the Bank shall pay the participant’s beneficiary. Benefits shall not be payable to anyone other than the beneficiary, and shall terminate on the death of the beneficiary.
Stock Options | Stock Options. Compensation cost is measured based on the grant-date fair value of the equity instruments issued, and recognized over the vesting period during which an employee provides service in exchange for the award.
Earnings Per Share | Earnings Per Share. Basic earnings per share available to common stockholders is computed using the weighted-average number of common shares outstanding. Diluted earnings per share available to common stockholders includes the effect of all weighted-average dilutive potential common shares (stock options and restricted stock grants) outstanding during each period.
Comprehensive Income | Comprehensive Income. Comprehensive income consists of net income and other comprehensive income (loss), net of applicable income taxes. Other comprehensive income (loss) includes unrealized depreciation on available-for-sale securities, unrealized depreciation on available-for-sale securities for which a portion of an other-than-temporary impairment has been recognized in income, and changes in the funded status of defined benefit pension plans.
Transfers Between Fair Value Hierarchy Levels | Transfers Between Fair Value Hierarchy Levels. Transfers in and out of Level 1 (quoted market prices), Level 2 (other significant observable inputs) and Level 3 (significant unobservable inputs) are recognized on the period ending date.
Wealth Management Assets and Fees | Wealth Management Assets and Fees. Assets managed in fiduciary or investment management accounts by the Company are not included in the consolidated balance sheets since such items are not assets of the Company or its subsidiaries. Fees from fiduciary or investment management activities are recorded on a cash basis over the period in which the service is provided. Fees are generally a function of the market value of assets managed and administered, the volume of transactions, and fees for other services rendered, as set forth in the agreement between the customer and the Company. This revenue recognition involves the use of estimates and assumptions, including components that are calculated based on asset valuations and transaction volumes. Any out-of-pocket expenses or services not typically covered by the fee schedule for fiduciary activities are charged directly to the account on a gross basis as revenue is incurred. The Southern Wealth Management division, which is a division of the Bank, held fiduciary assets totaling $104.8 million and $102.0 million as of March 31, 2024 and June 30, 2023, respectively, and investment management assets totaling $480.0 million and $464.2 million as of March 31, 2024 and June 30, 2023, respectively.
New Accounting Pronouncements | New Accounting Pronouncements: In January 2021, the Financial Accounting Standards Board (“FASB”), published ASU 2021-01, “Reference Rate Reform. (Topic 848)”. ASU 2021-01 clarified that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. The ASU also amended the expedients and exceptions in Topic 848 to capture the incremental consequences of the scope clarification and to tailor the existing guidance to derivative instruments affected by the discounting transition. An entity may elect to apply the amendments in this update on a full retrospective basis as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or on a prospective basis to new modifications from any date within an interim period that includes or is subsequent to the date of the issuance of a final update, up to the date that financial statements are available to be issued. If an entity elects to apply any of the amendments in this update for an eligible hedging relationship, any adjustments as a result of those elections must be reflected as of the date the entity applies the election. Originally, the amendments in this update did not apply to contract modifications made after December 31, 2022, new hedging relationships entered into after December 31, 2022, and existing hedging relationships evaluated for effectiveness in periods after December 31, 2022 except for hedging relationships existing as of December 31, 2022, that apply certain optional expedients in which the accounting effects are recorded through the end of the hedging relationship (including periods after December 31, 2022). With the issuance of ASU 2022-06 Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, the sunset date for adoption of ASU 2021-01 was extended from December 31, 2022 to December 31, 2024. The Company is evaluating the impact of this ASU but does not expect it to have a material impact on the Company’s consolidated financial statements. ​ In March 2023, the FASB issued ASU 2023-02, “Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method.” This ASU permits reporting entities to elect to account for tax equity investments, regardless of the tax credit program for which the income tax credits are received, using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the income tax credits and other income tax benefits received and recognizes the net amortization and income tax credits and other income tax benefits in the income statement as a component of income tax expense. A reporting entity makes an accounting policy election to apply the proportional amortization method on a tax-credit-program-by-tax-credit-program basis rather than electing to apply the proportional amortization method at the reporting entity level or to individual investments. This ASU also requires specific disclosures of investments that generate income tax credits and other income tax benefits from a tax credit program for which the entity has elected to apply the proportional amortization method. The ASU is effective for fiscal years beginning after December 15, 2023. The Company does not expect adoption of ASU 2023-02 to have a material impact on its consolidated financial statements. ​ On July 1, 2023, the Company adopted ASU No. 2022-02, “Financial Instruments – Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures.” ASU 2022-02 eliminates the accounting guidance for TDRs in ASC 310-40, “Receivables – Troubled Debt Restructurings by Creditors” for entities that have adopted the CECL model introduced by ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2022-02 also requires that public business entities disclose current-period gross charge offs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, “Financial Instruments – Credit Losses – Measured at Amortized Cost.” The adoption of this update did not have a material impact on the Company’s consolidated financial statements. ​ In December 2023, the FASB issued ASU 2023-09, “Income Taxes - Improvements to Income Tax Disclosures (Topic 740)”. ASU 2023-09 was issued to address requests by investors and creditors for enhanced transparency and decision usefulness of income tax disclosures. Public business entities (PBEs) would be required to prepare an annual detailed, tabular tax rate reconciliation. All other entities would be required to provide qualitative disclosure on specific categories and individual jurisdictions that result in significant differences between the statutory and effective tax rates. All entities would be required to annually disclose taxes paid disaggregated by federal, state, and foreign taxes, as well as disaggregating taxes by individual jurisdiction if taxes paid exceed 5% of total income taxes paid. The ASU is effective for PBEs for fiscal years beginning after December 15, 2024. The Company does not expect adoption of ASU 2023-09 to have a material impact on its consolidated financial statements.
