Nature of Operations and Summary of Significant Accounting Policies |
Nature of Operations and Summary of Significant Accounting Policies | Note 1: Nature of Operations and Summary of Significant Accounting Policies Nature of Operations and Operating Segments Great Southern Bancorp, Inc. (“GSBC” or the “Company”) operates as a one-bank holding company. GSBC’s business primarily consists of the operations of Great Southern Bank (the “Bank”), which provides a full range of financial services to customers primarily located in Missouri, Iowa, Kansas, Minnesota, Nebraska and Arkansas. The Bank also originates commercial loans from lending offices in Atlanta; Charlotte, North Carolina; Chicago; Dallas; Denver; Omaha, Nebraska; Phoenix; and Tulsa, Oklahoma. The Company and the Bank are subject to regulation by certain federal and state agencies and undergo periodic examinations by those regulatory agencies. The Company’s banking operation is its only reportable segment. The banking operation is principally engaged in the business of originating residential and commercial real estate loans, construction loans, commercial business loans and consumer loans and funding these loans by attracting deposits from the general public, accepting brokered deposits and borrowing from the Federal Home Loan Bank and others. The operating results of this segment are regularly reviewed by management to make decisions about resource allocations and to assess performance. Selected information is not presented separately for the Company’s reportable segment, as there is no material difference between that information and the corresponding information in the consolidated financial statements. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for credit losses and the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans and fair values of financial instruments. In connection with the determination of the allowance for credit losses and the valuation of foreclosed assets held for sale, management obtains independent appraisals for significant properties. In addition, the Company considers that the determination of the carrying value of goodwill and intangible assets involves a high degree of judgment and complexity. Principles of Consolidation The consolidated financial statements include the accounts of Great Southern Bancorp, Inc., its wholly owned subsidiary, the Bank, and the Bank’s wholly owned subsidiaries, Great Southern Real Estate Development Corporation, GSB One LLC (including its wholly owned subsidiary, GSB Two LLC), Great Southern Financial Corporation, Great Southern Community Development Company, LLC (including its wholly owned subsidiary, Great Southern CDE, LLC), GS, LLC, GSSC, LLC, GSTC Investments, LLC, GS-RE Holding, LLC (including its wholly owned subsidiary, GS RE Management, LLC), GS-RE Holding II, LLC, GS-RE Holding III, LLC, VFP Conclusion Holding, LLC and VFP Conclusion Holding II, LLC. All significant intercompany accounts and transactions have been eliminated in consolidation. Federal Home Loan Bank Stock Federal Home Loan Bank common stock is a required investment for institutions that are members of the Federal Home Loan Bank system. The required investment in common stock is based on a predetermined formula, carried at cost and evaluated for impairment. Securities Available-for-sale securities, 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 are recorded, net of related income tax effects, in other comprehensive income. Held-to-maturity securities, which include any security for which the Company has the positive intent and ability to hold until maturity, are carried at historical cost adjusted for amortization of premiums and accretion of discounts. Amortization of premiums and accretion of discounts are recorded as interest income from securities. Realized gains and losses are recorded as net security gains (losses). Gains and losses on sales of securities are determined on the specific-identification method. The Company evaluates all securities quarterly to determine if any securities in a loss position require a provision for credit losses in accordance with ASC 326, Measurement of Credit Losses on Financial Instruments. The Company’s consolidated statements of income reflect the full impairment (that is, the difference between the security’s amortized cost basis and fair value) on debt securities that the Company intends to sell or would more likely than not be required to sell before the expected recovery of the amortized cost basis. For available-for-sale and held-to-maturity debt securities 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 for available-for-sale securities. The credit loss component recognized in earnings through a provision for credit loss is identified as the amount of principal cash flows not expected to be received over the remaining term of the security based on cash flow projections. Mortgage Loans Held for Sale Mortgage loans originated and intended for sale in the secondary market are carried at the lower of cost or fair value in the aggregate. Write-downs to fair value are recognized as a charge to earnings at the time the decline in value occurs. Nonbinding forward commitments to sell individual mortgage loans are generally obtained to reduce market risk on mortgage loans in the process of origination and mortgage loans held for sale. Gains and losses resulting from sales of mortgage loans are recognized when the respective loans are sold to investors. Fees received from borrowers to guarantee the funding of mortgage loans held for sale and fees paid to investors to ensure the ultimate sale of such mortgage loans are recognized as income or expense when the loans are sold or when it becomes evident that the commitment will not be used. Loans Originated by the Company Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding principal balances adjusted for any charge-offs, the allowance for credit losses, any deferred fees or costs on originated loans and unamortized premiums or discounts on purchased loans. Interest income is reported on the interest method and includes amortization of net deferred loan fees and costs over the loan term. Past due status is based on the contractual terms of a loan. Generally, loans are placed on nonaccrual status at 90 days past due and interest is considered a loss, unless the loan is well secured and in the process of collection. Payments received on nonaccrual loans are applied to principal until the loans are returned to accrual status. Loans are returned to accrual status when all payments contractually due are brought current, payment performance is sustained for a period of time, generally six months, and future payments are reasonably assured. With the exception of consumer loans, charge-offs on loans are recorded when available information indicates a loan is not fully collectible and the loss is reasonably quantifiable. Consumer loans are charged-off at specified delinquency dates consistent with regulatory guidelines. Allowance for Credit Losses The allowance for credit losses is measured using an average historical loss model that incorporates relevant information about past events (including historical credit loss experience on loans with similar risk characteristics), current conditions, and reasonable and supportable forecasts that affect the collectability of the remaining cash flows over the contractual term of the loans. The allowance for credit losses is measured on a collective (pool) basis. Loans are aggregated into pools based on similar risk characteristics, including borrower type, collateral and repayment types and expected credit loss patterns. Loans that do not share similar risk characteristics, primarily classified loans with a balance greater than or equal to $100,000, are evaluated on an individual basis. For loans evaluated for credit losses on a collective basis, average historical loss rates are calculated for each pool using the Company’s historical net charge-offs (combined charge-offs and recoveries by observable historical reporting period) and outstanding loan balances during a lookback period. Lookback periods can be different based on the individual pool and represent management’s credit expectations for the pool of loans over the remaining contractual life. In certain loan pools, if the Company’s own historical loss rate is not reflective of the loss expectations, the historical loss rate is augmented by industry and peer data. The calculated average net charge-off rate is then adjusted for current conditions and reasonable and supportable forecasts. These adjustments increase or decrease the average historical loss rate to reflect expectations of future losses given economic forecasts of key macroeconomic variables including, but not limited to, unemployment rate, gross domestic product (“GDP”), commercial real estate price index, consumer sentiment and construction spending. The adjustments are based on results from various regression models projecting the impact of the macroeconomic variables to loss rates. The forecast is used for a reasonable and supportable period before reverting to historical averages. The forecast-adjusted loss rate is applied to the principal balance over the remaining contractual lives, adjusted for expected prepayments. The contractual term excludes expected extensions, renewals and modifications. Additionally, the allowance for credit losses considers other qualitative factors not included in historical loss rates or macroeconomic forecasts such as changes in portfolio composition, underwriting practices, or significant unique events or conditions. In addition, ASU 2016-13 requires an allowance for off balance sheet credit exposures: unfunded lines of credit, undisbursed portions of loans, written residential and commercial commitments, and letters of credit. To determine the amount needed for allowance purposes, a utilization rate is determined either by the model or internally for each pool. Our loss model calculates the reserve on unfunded commitments based upon the utilization rate multiplied by the average loss rate factors in each pool with unfunded and committed balances. The liability for unfunded lending commitments utilizes the same model as the allowance for credit losses on loans; however, the liability for unfunded lending commitments incorporates assumptions for the portion of unfunded commitments that are expected to be funded. Loans Acquired in Business Combinations Loans acquired in business combinations under ASC Topic 805, Business Combinations, required the use of the acquisition method of accounting. Therefore, such loans were initially recorded at fair value in accordance with the fair value methodology prescribed in ASC Topic 820, Fair Value Measurements and Disclosures. The Company’s historical acquisitions all occurred under previous US GAAP prior to the Company’s adoption of ASU 2016-13. No allowance for credit losses related to the acquired loans was recorded on the acquisition date as the fair value of the loans acquired incorporates assumptions regarding credit risk. Loans acquired are recorded at fair value in accordance with the fair value methodology prescribed in ASC Topic 820. The fair value estimates associated with the loans include estimates related to expected prepayments and the amount and timing of undiscounted expected principal, interest and other cash flows. For acquired loans not acquired in conjunction with an FDIC-assisted transaction that were not considered to be purchased credit-impaired loans, the Company evaluated those loans acquired in accordance with the provisions of ASC Topic 310-20, Nonrefundable Fees and Other Costs. The fair value discount on these loans is accreted into interest income over the weighted average life of the loans using a constant yield method. These loans are not considered impaired loans. The Company’s historical acquisitions all occurred under previous US GAAP prior to the Company’s adoption of ASU 2016-13. The Company evaluated purchased credit-impaired loans in accordance with the provisions of ASC Topic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality. Loans acquired in business combinations with evidence of credit deterioration since origination and for which it is probable that all contractually required payments will not be collected were considered to be credit impaired. Evidence of credit quality deterioration as of the purchase dates may include information such as past-due and nonaccrual status, borrower credit scores and recent loan to value percentages. Acquired credit-impaired loans that are accounted for under the accounting guidance for loans acquired with deteriorated credit quality are initially measured at fair value, which includes estimated future credit losses expected to be incurred over the life of the loans. At the date of CECL adoption, the Company did not reassess whether purchased credit impaired (PCI) loans met the criteria of purchased with credit deterioration (PCD) loans. The Company evaluated all of its loans acquired in conjunction with its FDIC-assisted transactions in accordance with the provisions of ASC Topic 310-30. For purposes of applying ASC 310-30, loans acquired in FDIC-assisted business combinations are aggregated into pools of loans with common risk characteristics. All loans acquired in the FDIC transactions, both covered and not covered by loss sharing agreements, were deemed to be purchased credit-impaired loans as there is general evidence of credit deterioration since origination in the pools and there is some probability that not all contractually required payments will be collected. As a result, related discounts are recognized subsequently through accretion based on changes in the expected cash flows of these acquired loans. Prior to the adoption of ASU 2016-13, the expected cash flows of the acquired loan pools in excess of the fair values recorded, referred to as the accretable yield, was recognized in interest income over the remaining estimated lives of the loan pools for impaired loans accounted for under ASC Topic 310-30. Subsequent to acquisition date, the Company estimated cash flows expected to be collected on pools of loans sharing common risk characteristics, which are treated in the aggregate when applying various valuation techniques. Increases in the Company’s cash flow expectations have been recognized as increases to the accretable yield while decreases have been recognized as impairments through the allowance for credit losses. Other Real Estate Owned and Repossessions Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value less estimated cost to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less estimated cost to sell. Revenue and expenses from operations and changes in the valuation allowance are included in net expense on foreclosed assets. Other real estate owned also includes bank premises formerly, but no longer, used for banking activities, as well as property originally acquired for future expansion but no longer intended to be used for that purpose. Premises and Equipment Premises and equipment are stated at cost less accumulated depreciation. Depreciation is charged to expense using the straight-line and accelerated methods over the estimated useful lives of the assets. Leasehold improvements are capitalized and amortized using the straight-line and accelerated methods over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. Material lease obligations consist of leases for various loan offices and banking centers. All of our leases are classified as operating leases (as they were prior to January 1, 2019), and therefore were previously not recognized on the Company’s consolidated statements of financial condition. With the adoption of ASU 2016-02, these operating leases are now included as a right of use asset in the premises and equipment line item on the Company’s consolidated statements of financial condition. The corresponding lease liability is included in the accrued expenses and other liabilities line item on the Company’s consolidated statements of financial condition. The calculated amounts of the right of use assets and lease liabilities 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 for an extended term in the calculation of the right of use asset and lease liability. 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 right of use asset and lease liability. Regarding the discount rate, the Company uses 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 is the FHLBank borrowing rate for the term corresponding to the expected term of the lease. Long-Lived Asset Impairment The Company evaluates the recoverability of the carrying value of long-lived assets whenever events or circumstances indicate the carrying amount may not be recoverable. If a long-lived asset is tested for recoverability and the undiscounted estimated future cash flows expected to result from the use and eventual disposition of the asset is less than the carrying amount of the asset, the asset cost is adjusted to fair value and an impairment loss is recognized as the amount by which the carrying amount of a long-lived asset exceeds its fair value. No material asset impairment was recognized during the years ended December 31, 2023, 2022 and 2021. Goodwill and Intangible Assets Goodwill is evaluated annually for impairment or more frequently if impairment indicators are present. The annual, or interim, goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount and an impairment charge is recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value. The Company still may perform a qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. Deposit intangible assets are amortized on the straight-line basis generally over a period of seven years. Arena naming rights intangible assets are being amortized on the straight-line basis generally over a period of fifteen years. Such assets are periodically evaluated as to the recoverability of their carrying value. A summary of goodwill and intangible assets is as follows: ​

​ Loan Servicing and Origination Fee Income Loan servicing income represents fees earned for servicing real estate mortgage loans owned by various investors. The fees are generally calculated on the outstanding principal balances of the loans serviced and are recorded as income when earned. Loan origination fees, net of direct loan origination costs, are recognized as income using the level-yield method over the contractual life of the loan. Stockholders’ Equity The Company is incorporated in the State of Maryland. Under Maryland law, there is no concept of “Treasury Shares.” Instead, shares purchased by the Company constitute authorized but unissued shares under Maryland law. Accounting principles generally accepted in the United States of America state that accounting for treasury stock shall conform to state law. The cost of shares purchased by the Company has been allocated to common stock and retained earnings balances. Earnings Per Common Share Basic earnings per common share are computed based on the weighted average number of common shares outstanding during each year. Diluted earnings per common share are computed using the weighted average common shares and all potential dilutive common shares outstanding during the year. Earnings per common share (EPS) were computed as follows: ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

​ Options outstanding at December 31, 2023, 2022 and 2021, to purchase 749,833, 559,484 and 383,338 shares of common stock, respectively, were not included in the computation of diluted earnings per common share for each of the years because the exercise prices of such options were greater than the average market prices of the common stock for the years ended December 31, 2023, 2022 and 2021, respectively. Stock Compensation Plans The Company has stock-based employee compensation plans, which are described more fully in Note 20. In accordance with FASB ASC 718, Compensation – Stock Compensation, compensation cost related to share-based payment transactions is recognized in the Company’s consolidated financial statements based on the grant-date fair value of the award using the modified prospective transition method. For the years ended December 31, 2023, 2022 and 2021, share-based compensation expense totaling $1.6 million, $1.4 million and $1.2 million, respectively, was included in salaries and employee benefits expense in the consolidated statements of income. Cash Equivalents The Company considers all liquid investments with original maturities of three months or less to be cash equivalents. At December 31, 2023 and 2022, cash equivalents consisted of interest-bearing deposits in other financial institutions. At December 31, 2023, nearly all of the interest-bearing deposits were uninsured and held at the Federal Home Loan Bank or the Federal Reserve Bank. Income Taxes The Company accounts for income taxes in accordance with income tax accounting guidance (FASB 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. At December 31, 2023 and 2022, no valuation allowance was established. 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. Derivatives and Hedging Activities FASB ASC 815, Derivatives and Hedging, provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (a) how and why an entity uses derivative instruments, (b) how the entity accounts for derivative instruments and related hedged items and (c) how derivative instruments and related hedged items affect an entity’s financial position, financial performance and cash flows. Further, qualitative disclosures are required that explain the Company’s objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative instruments. For detailed disclosures on derivatives and hedging activities, see Note 16. As required by FASB ASC 815, the Company records all derivatives in the statement of financial condition at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Recent Accounting Pronouncements In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. ASU 2020-04 provides relief for companies preparing for discontinuation of interest rates such as the London Interbank Offered Rate (“LIBOR”). LIBOR is a benchmark interest rate referenced in a variety of agreements that are used by numerous entities. After 2021, certain LIBOR rates may no longer be published. As a result, LIBOR is expected to be discontinued as a reference rate. Other interest rates used globally could also be discontinued for similar reasons. ASU 2020-04 provides optional expedients and exceptions to contracts, hedging relationships and other transactions affected by reference rate reform. The main provisions for contract modifications include optional relief by allowing the modification as a continuation of the existing contract without additional analysis and other optional expedients regarding embedded features. Optional expedients for hedge accounting permit changes to critical terms of hedging relationships and to the designated benchmark interest rate in a fair value hedge and also provide relief for assessing hedge effectiveness for cash flow hedges. ASU 2020-04 was effective upon issuance; however, the guidance was originally only available generally through December 31, 2022. Based upon amendments provided in ASU 2022-06 discussed below, provisions of ASU 2020-04 can now generally be applied through December 31, 2024. The application of ASU 2020-04 has not had, and is not expected to have, a material impact on the Company’s consolidated financial statements. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope. ASU 2021-01 clarifies that certain optional expedients and exceptions in ASC 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. ASU 2021-01 also amends the expedients and exceptions in ASC 848 to capture the incremental consequences of the scope clarification and to tailor the existing guidance to derivative instruments affected by the discounting transition. ASU 2021-01 was effective upon issuance; however, the guidance was originally only available generally through December 31, 2022. Based upon amendments provided in ASU 2022-06 discussed below, provisions of ASU 2021-01 can now generally be applied through December 31, 2024. ASU 2021-01 has not had, and is not expected to have, a material impact on the Company’s consolidated financial statements. In March 2022, the FASB issued ASU 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging – Portfolio Layer Method. ASU 2022-01 further clarifies certain targeted improvements to the optional hedge accounting model that were made under ASU 2017-12. ASU 2022-01 expands the last-of-layer method and renames this method to portfolio layer method to reflect this expansion, as well as expanding the scope of the portfolio layer method to include nonprepayable financial assets. It also specifies eligible hedging instruments and provides additional guidance on the accounting for and disclosure of hedge basis adjustments that are applicable to the portfolio layer method. ASU 2022-01 permits an entity to apply the same portfolio hedging method to both prepayable and nonprepayable financial assets, thereby allowing consistent accounting for similar hedges. ASU 2022-01 became effective for the Company on January 1, 2023. The adoption of ASU 2022-01 did not have a material impact on the Company’s consolidated financial statements. In March 2022, the FASB issued ASU 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. ASU 2022-02 eliminates the troubled debt restructuring recognition and measurement guidance and, instead, requires that an entity evaluate whether a loan modification represents a new loan or a continuation of an existing loan. It also enhances existing disclosure requirements and introduces new requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty. ASU 2022-02 became effective for the Company on January 1, 2023. The adoption of ASU 2022-02 did not have a material impact on the Company’s consolidated financial statements. The adoption of this ASU does, however, require changes in disclosures related to certain loan modifications. In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848. ASU 2022-06 extends the period of time entities can utilize the reference rate reform relief guidance provided by ASU 2020-04 and ASU 2021-01, which are discussed above. ASU 2022-06 was effective upon issuance and defers the sunset date of this prior guidance to December 31, 2024, after which entities will no longer be permitted to apply the relief guidance in Topic 848. ASU 2022-06 has not had, and is not expected 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. ASU 2023-02 is intended to improve the accounting and disclosures for investments in tax credit structures. ASU 2023-02 allows entities to elect to account for qualifying tax equity investments using the proportional amortization method, regardless of the program giving rise to the related income tax credits. Previously, this method was only available for qualifying tax equity investments in low-income housing tax credit structures. Currently, the Company does not have a material amount of tax credit structures, other than low-income housing tax credit structures. ASU 2023-02 became effective for the Company on January 1, 2024. The early adoption of ASU 2023-02 did not have a material impact on the Company’s consolidated financial statements. In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. ASU 2023-07 expands reportable segment disclosure requirements through enhanced disclosures about significant segment expenses. ASU 2023-07 implements a new requirement to disclose significant segment expenses regularly provided to the chief operating decision maker, expands certain annual disclosures to interim periods, clarifies that single reportable segment entities must apply Topic 280 in its entirety and permits more than one measure of segment profit or loss to be reported under certain conditions. ASU 2023-07 is effective for the Company for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is evaluating the requirements of the expanded segment disclosures but does not currently expect the additional disclosures to have a material impact on the Company’s consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 is focused on additional income tax disclosures and requires public business entities, on an annual basis, to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income by the applicable statutory income tax rate). ASU 2023-09 is effective for the Company for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2024, with early adoption permitted. While the Company is currently assessing the impact applying this standard will have on its income tax disclosures, the adoption of ASU 2023-09 is currently not expected to have a material impact on the Company’s consolidated financial statements. Correction of an Immaterial Error in Prior Period Financial Statements Certain prior period amounts in the Consolidated Statements of Cash Flows have been corrected as discussed below. No other financial statements or notes thereto were impacted by these corrections. The Company has corrected its 2022 and 2021 Consolidated Statements of Cash Flows presentation within this Annual Report on Form 10-K for an error in classification within the operating activities section of the statements of cash flows regarding amortization of terminated hedging transactions and for an error in classification regarding investments in tax credit partnerships between the operating activities and investing activities sections of the statements of cash flows. For the item related to the terminated hedging transactions, the Company is now including the amortization from accumulated other comprehensive income and related deferred taxes recognized in interest income as an item not providing cash in accretion of deferred income, premiums, discounts and other. This was previously included in net changes in prepaid expenses and other assets. For the item related to investments in tax credit partnerships, the Company is now including the amounts invested as an item using cash in the investing activities section. This was previously included in net changes in prepaid expenses and other assets in the operating activities section. The Company assessed the materiality of this change in presentation on prior period consolidated financial statements in accordance with SEC Staff Accounting Bulletin No. 99, “Materiality,” (ASC Topic 250, Accounting Changes and Error Corrections).
