Summary of Significant Accounting Policies |
Summary of Significant Accounting Policies | Note 1—Summary of Significant Accounting Policies Nature of Operations SouthState Corporation is a financial holding company headquartered in Winter Haven, Florida, and was incorporated under the laws of South Carolina in 1985. We provide a wide range of banking services and products to our customers through our Bank. The Bank operates SouthState Advisory, Inc., a wholly owned registered investment advisor. The Bank also operates SouthState|Duncan-Williams, Securities Corp. (“SouthState|DuncanWilliams”), a registered broker-dealer, headquartered in Memphis, Tennessee that serves primarily institutional clients across the U.S. in the fixed income business. The Bank also operates SouthState Advisory, Inc., a wholly owned registered investment advisor, and Corporate Billing, LLC (“Corporate Billing”), a transaction-based finance company headquartered in Decatur, Alabama that provides factoring, invoicing, collection and accounts receivable management services to transportation companies and automotive parts and service providers nationwide. Corporate Billing’s previous holding company CBI Holding Company, LLC and its subsidiary CBI Real Estate Holding, LLC were merged into CBI Billing effective November 30, 2023. The Company also owns SSB Insurance Corp., a captive insurance subsidiary pursuant to Section 831(b) of the U.S. Tax Code. In addition, the Company operates a correspondent banking and capital markets division within the national bank subsidiary, of which the majority of its bond salesmen, traders and operational personnel are housed in facilities located in in facilities located in Atlanta, Georgia, Memphis, Tennessee, Walnut Creek, California, and Birmingham, Alabama. The Bank provides general banking services within a six (6) state footprint in Alabama, Florida, Georgia, North Carolina, South Carolina and Virginia. In late 2023, the Bank formed SSB First Street Corporation, an investment subsidiary headquartered in Wilmington, Delaware, to hold tax-exempt municipal investment securities as part of the Bank’s investment portfolio. ​ The accounting and reporting policies of the Company and its consolidated subsidiary conform to accounting principles generally accepted in the United States of America (“U.S. GAAP”). There are 13 unconsolidated subsidiaries of the Company that were established for the purpose of issuing in the aggregate approximately $118.6 million of trust preferred securities at December 31, 2023. See Note 11—Other Borrowings for further detailed descriptions of our trust preferred securities. ​ Unless otherwise mentioned or unless the context requires otherwise, references herein to “SouthState,” the “Company” “we,” “us,” “our” or similar references mean SouthState Corporation and its consolidated subsidiaries. References to the “Bank” means SouthState Bank, National Association. Basis of Consolidation The consolidated financial statements include the accounts of the Company and other entities in which it has a controlling financial interest. All significant intercompany balances and transactions have been eliminated in consolidation. Assets held by the Company in trust are not assets of the Company and are not included in the accompanying consolidated financial statements. Reportable Segment The Company, through the Bank, provides a broad range of financial services to individuals and companies primarily in South Carolina, North Carolina, Florida, Alabama, Georgia and Virginia. These services include, but not limited to, demand, time and savings deposits; lending and credit card servicing; ATM processing; mortgage banking services; correspondent banking services and wealth management and trust services. The Company’s operations are managed and financial performance is evaluated on an organization-wide basis. Accordingly, the Company’s banking and finance operations are not considered by management to constitute more than one reportable operating segment. ​ 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 as of the date of the consolidated balance sheet 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 in the near term relate to the determination of the allowance for credit losses for loans and investment securities held to maturity, fair value of financial instruments, fair values of assets and liabilities acquired in business combinations, evaluating impairment of investment securities, goodwill and other intangible impairment tests and valuation of deferred tax assets. ​ In connection with the determination of the allowance for credit losses, management has identified specific loans as well as adopted a policy of providing amounts for loan valuation purposes which are not identified with any specific loan but are derived from models based on macroeconomic factors and forecasts. Management believes that the allowance for credit losses is appropriate. While management uses available information to recognize losses on loans, future additions or reductions to the allowance for credit losses may be necessary based on changes in economic forecasts. In addition, regulatory agencies, as an integral part of the examination process, periodically review the banking subsidiary’s allowance for credit losses. Such agencies may require additions to the allowance for credit losses based on their judgments about information available to them at the time of their examination. Concentrations of Credit Risk The Bank provides agribusiness, commercial, and residential and other consumer loans to customers primarily throughout South Carolina, North Carolina, Florida, Alabama, Virginia and Georgia. Although the Bank has a diversified loan portfolio, a substantial portion of their borrowers’ abilities to honor their contracts is dependent upon economic conditions within South Carolina, North Carolina, Florida, Alabama, Virginia, Georgia and the surrounding regions. ​ The Company considers concentrations of credit to exist when, pursuant to regulatory guidelines, the amounts loaned to a multiple number of borrowers engaged in similar business activities which would cause them to be similarly impacted by general economic conditions represents 25% of total Tier 1 capital plus regulatory adjusted allowance for credit losses of the Company, or $1.2 billion at December 31, 2023. Based on this criteria, we had eight such credit concentrations at December 31, 2023, including loans to lessors of nonresidential buildings (except mini warehouses) of $6.2 billion, loans secured by owner occupied office buildings (including medical office buildings) of $1.9 billion, loans secured by owner occupied nonresidential buildings (excluding office buildings) of $1.8 billion, loans to lessors of residential buildings (investment properties and multi-family) of $2.4 billion, loans secured by 1st mortgage 1-4 family owner occupied residential property (including condos and home equity lines) of $8.8 billion, loans secured by jumbo (original loans greater than $726,200) 1st mortgage 1-4 family owner occupied residential property of $2.6 billion, loans secured by business assets including accounts receivable, inventory and equipment of $2.2 billion, and loans to consumers secured by non-real estate of $1.2 billion. The risk for these loans and for all loans is managed collectively through the use of credit underwriting practices developed and updated over time. The loss estimate for these loans is determined using our standard ACL methodology. ​ With some financial institutions adopting CECL in the first quarter of 2020, banking regulators established new guidelines for calculating credit concentrations. Banking regulators set the guidelines for construction, land development and other land loans to total less than 100% of total Tier 1 capital less modified CECL transitional amount plus ACL (CDL concentration ratio) and for total commercial real estate loans (construction, land development and other land loans along with other non-owner occupied commercial real estate and multifamily loans) to total less than 300% of total Tier 1 capital less modified CECL transitional amount plus ACL (CRE concentration ratio). Both ratios are calculated by dividing certain types of loan balances for each of the two categories by the Bank’s total Tier 1 capital less modified CECL transitional amount plus ACL. At December 31, 2023 and 2022, the Bank’s CDL concentration ratio was 59.7% and 64.8%, respectively, and its CRE concentration ratio was 236.5% and 249.0%, respectively. As of December 31, 2023, the Bank was below the established regulatory guidelines and we monitor these two ratios as part of our concentration management processes. Cash and Cash Equivalents For the purpose of presentation in the consolidated statements of cash flows, cash and cash equivalents include cash on hand, cash items in process of collection, amounts due from banks including restricted pledged cash, interest bearing deposits with banks, purchases of securities under agreements to resell, and federal funds sold. The restricted cash is used as collateral on the counterparty for the interest rate swap contracts with loan customers of respondent bank customers of the Correspondent Banking Division. Due from bank balances are maintained at other financial institutions. Federal funds sold are generally purchased and sold for one-day periods, but may, from time to time, have longer terms. ​ The Company enters from time to time into purchases of securities under agreements to resell substantially identical securities. When the Company enters into such repurchase agreements, the securities purchased under agreements to resell generally consist of U.S. government-sponsored entities and agency mortgage-backed securities. The Company may elect to use other asset classes at its discretion. It is the Company’s practice to take possession of securities purchased under agreements to resell. The securities are delivered into the Company’s account maintained by a third-party custodian designated by the Company under a written custodial agreement that explicitly recognizes the Company’s interest in the securities. The Company monitors the market value of the underlying securities, including accrued interest, which collateralizes the related receivable on agreements to resell. These agreements were considered to be cash equivalents with maturities within less than one year. The Company held $2.5 million in securities under agreements to resell at December 31, 2023. Trading Securities Through its Correspondent Banking Department and the Bank’s wholly owned broker dealer SouthState|Duncan-Williams, the Company purchases trading securities and subsequently sells them to their customers to take advantage of market opportunities, when presented, for short-term revenue gains. Securities purchased for this portfolio are primarily municipals, treasuries and mortgage-backed agency securities and are held for short periods of time. This portfolio is carried at fair value and realized and unrealized gains and losses are included in trading securities revenue, a component of Correspondent Banking and Capital Market Income in our Consolidated Statements of Income. Investment Securities Debt securities that management has the positive intent and ability to hold to maturity are classified as “held to maturity” and carried at amortized cost. Securities not classified as held to maturity, including equity securities with readily determinable fair values, are classified as “available for sale” and carried at fair value with unrealized gains and losses excluded from earnings and reported in Other Comprehensive Income. ​ Purchase premiums and discounts are recognized in interest income using methods approximating the interest method over the terms of the securities. Gains and losses realized on sales of securities available for sale are determined using the specific identification method. ​ In accordance with as ASC Subtopic 326-30, Financial Instruments—Credit Losses—Available for sale Debt Securities, Management evaluates securities for impairment where there has been a decline in fair value below the amortized cost basis of a security to determine whether there is a credit loss associated with the decline in fair value on at least a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. For securities designated as held for sale, credit losses are calculated individually, rather than collectively, using a discounted cash flow method, whereby management compares the present value of expected cash flows with the amortized cost basis of the security. The credit loss component would be recognized through the provision for credit losses. Consideration is given to (1) the financial condition and near-term prospects of the issuer including looking at default and delinquency rates, (2) the outlook for receiving the contractual cash flows of the investments, (3) the extent to which the fair value has been less than cost, (4) our intent to hold the security as well as there being no requirement to sell the security, (5) the anticipated outlook for changes in the general level of interest rates, (6) credit ratings, (7) third-party guarantees, and (8) collateral values. In analyzing an issuer’s financial condition, management considers whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, the results of reviews of the issuer’s financial condition, and the issuer’s anticipated ability to pay the contractual cash flows of the investments. The Company performed an analysis that determined that the following securities have a zero expected credit loss: U.S. Treasury Securities, Agency-Backed Securities including securities issued by Ginnie Mae, Fannie Mae, FHLB, FFCB and SBA. All of the U.S. Treasury and Agency-Backed Securities have the full faith and credit backing of the United States Government or one of its agencies. Municipal securities and all other securities that do not have a zero expected credit loss are evaluated quarterly to determine whether there is a credit loss associated with a decline in fair value. All debt securities in an unrealized loss position as of December 31, 2023 continue to perform as scheduled and we do not believe there is a credit loss or a provision for credit losses is necessary. Also, as part of our evaluation of our intent and ability to hold investments, we consider our investment strategy, cash flow needs, liquidity position, capital adequacy and interest rate risk position. We do not currently intend to sell the securities within the portfolio and it is not more-likely-than-not that we will be required to sell the debt securities. ​ Other investments include stock acquired for regulatory purposes, investments in unconsolidated subsidiaries and other nonmarketable investment securities. Stock acquired for regulatory purposes include Federal Home Loan Bank of Atlanta (“FHLB”) stock and Federal Reserve Bank (“FRB”) stock. These securities do not have a readily determinable fair value because their ownership is restricted and they lack a market for trading. As a result, these securities are carried at cost and are periodically evaluated for impairment. Investments in unconsolidated subsidiaries represent a minority investment in SCBT Capital Trust I, SCBT Capital Trust II, SCBT Capital Trust III, TSB Statutory Trust I, SAVB Capital Trust I, SAVB Capital Trust II, Southeastern Bank Financial Statutory Trust I, Southeastern Bank Financial Statutory Trust II, Provident Community Bancshares Capital Trust I, FCRV Statutory Trust I, Community Capital Statutory Trust I, CSBC Statutory Trust I, and Provident Community Bancshares Capital Trust II. These investments are recorded at cost and the Company receives quarterly dividend payments on these investments. Other nonmarketable investment securities consist of Business Development Corporation stock and stock in Banker’s Banks. These investments also do not have a readily determinable fair value because their ownership is restricted and they lack a market for trading. As a result, these securities are carried at cost and are periodically evaluated for impairment. Loans Held for Sale The Company sells residential mortgages to government sponsored entities (“GSEs”) and mortgage and third-party investors, who may issue securities backed by pools of such loans. The Company retains no beneficial interests in these sales, but may retain the servicing rights for the loans sold. The Company is obligated to subsequently repurchase a loan if the purchaser discovers a representation or warranty violation such as noncompliance with eligibility or servicing requirements, or customer fraud, that should have been identified in a loan file review. Mortgage loans held for sale are accounted for at fair value on an individual loan basis. Estimated fair value is determined on the basis of existing forward commitments, or the current market value of similar loans. Changes in the fair value, and realized gains and losses on the sales of mortgage loans, are reported in Mortgage Banking Income, a component of Noninterest Income in our Consolidated Statements of Income. ​ Loans Loans that management has originated and has the intent and ability to hold for the foreseeable future or until maturity or pay off generally are reported at their unpaid principal balances, less unearned income and net of any deferred loan fees and costs. Unearned income on installment loans is recognized as income over the terms of the loans by methods that approximate the interest method. Interest on other loans is calculated by using the simple interest method on daily balances of the principal amount outstanding. ​ Premiums and discounts on purchased loans and non-refundable loan origination and commitment fees, net of direct costs of originating or acquiring loans, are deferred and recognized over the contractual or estimated lives of the related loans as an adjustment to the loans’ constant effective yield, which is included in interest income on loans. ​ We place loans on nonaccrual once reasonable doubt exists about the collectability of all principal and interest due. Generally, this occurs when principal or interest is 90 days or more past due, unless the loan is well secured and in the process of collection and excludes factored receivables. For factored receivables, which are commercial trade credits rather than promissory notes, the Company’s practice, in most cases, is to charge-off unpaid recourse receivables when they become 90 days past due from the invoice due date and the nonrecourse receivables when they become 120 days past due from the statement due date. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on non-accrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. ​ A loan is evaluated individually for loss when it is on nonaccrual and has a net book balance over $1 million. Large pools of homogeneous loans are collectively evaluated for loss and reserved at the pool level. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as nonaccrual, provided that management expects to collect all amounts due, including interest accrued at the contractual interest rate for the period of delay. Modifications to Troubled Borrowers As of January 1, 2023, the Company adopted and applied prospectively ASU No. 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures, that requires the elimination of designation of loans as TDRs. Management measures expected credit losses over the contractual term of a loan. When determining the contractual term, the Company considers expected prepayments but is precluded from considering expected extensions, renewals, or modifications. Longstanding TDR accounting rules were replaced as of January 1, 2023 with ASU No. 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures (See Recent Accounting and Regulatory Pronouncements section of this Note 1). In accordance with the adoption of ASU 2022-02, any loans modified to a borrower experiencing financial difficulty are reviewed by the Bank to determine if an interest rate reduction, a term extension, an other-than-insignificant payment delay, a principal forgiveness, or any combination of these has occurred. Allowance for Credit Losses (“ACL”) The Company complies with the requirements of Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, sometimes referred to herein as ASU 2016-13. Topic 326 was subsequently amended by ASU No. 2019-11, Codification Improvements to Topic 326, Financial Instruments-Credit Losses; ASU No. 2019-05, Codification Improvements to Topic 326, Financial Instruments-Credit Losses; and ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. This standard applies to all financial assets measured at amortized cost and off balance sheet credit exposures, including loans, investment securities and unfunded commitments. ​ ACL – Investment Securities Management uses a systematic methodology to determine its ACL for investment securities held to maturity. The ACL is a valuation account that is deducted from the amortized cost basis to present the net amount expected to be collected on the held to maturity portfolio. Management considers the effects of past events, current conditions, and reasonable and supportable forecasts on the collectability of the loan portfolio. The Company’s estimate of its ACL involves a high degree of judgment; therefore, management’s process for determining expected credit losses may result in a range of expected credit losses. Management monitors the held to maturity portfolio to determine whether a valuation account should be recorded. As of December 31, 2023, the Company had $2.5 billion of held to maturity securities and no related valuation account. As of December 31, 2023, the held to maturity portfolio consisted of U.S. Government Agency, U.S. Government Agency Residential and Commercial Mortgage-backed securities, and Small Business Administration loan-backed securities. At December 31, 2023, management does not believe that a fair value below amortized cost is due to credit related factors. ​ ASC Subtopic 326-30, Financial Instruments—Credit Losses—Available for sale Debt Securities, changed the accounting for recognizing impairment on available for sale debt securities. Each quarter, management evaluates impairment where there has been a decline in fair value below the amortized cost basis of a security to determine whether there is a credit loss associated with the decline in fair value. Management considers the nature of the collateral, potential future changes in collateral values, default rates, delinquency rates, third-party guarantees, credit ratings, interest rate changes since purchase, volatility of the security’s fair value and historical loss information for financial assets secured with similar collateral among other factors. Credit losses are calculated individually, rather than collectively, using a discounted cash flow method, whereby management compares the present value of expected cash flows with the amortized cost basis of the security. The credit loss component would be recognized through the Provision for Credit Losses in the Consolidated Statements of Income. Management excludes the accrued interest receivable balance from the amortized cost basis in measuring expected credit losses on the investment securities and does not record an allowance for credit losses on accrued interest receivable as the Company reverses any accrued interest against interest income if an investment is placed on nonaccrual status. As of December 31, 2023 and December 31, 2022, the accrued interest receivables for investment securities recorded in Other Assets were $26.5 million and $28.2 million, respectively. ACL – Loans The ACL for loans held for investment reflects management’s estimate of losses that will result from the inability of our borrowers to make required loan payments. The Company established the incremental increase in the ACL at adoption through equity and subsequent adjustments through a provision for or recovery of credit losses recorded to earnings. The Company records loans charged off against the ACL and subsequent recoveries, if any, increase the ACL when they are recognized. ​ Management uses systematic methodologies to determine its ACL for loans held for investment and certain off-balance-sheet credit exposures. The ACL is a valuation account that is deducted from the amortized cost basis to present the net amount expected to be collected on the loan portfolio. Management considers the effects of past events, current conditions, and reasonable and supportable forecasts on the collectability of the loan portfolio. The Company’s estimate of its ACL involves a high degree of judgment; therefore, management’s process for determining expected credit losses may result in a range of expected credit losses. The Company’s ACL recorded in the balance sheet reflects management’s best estimate within the range of expected credit losses. The Company recognizes in net income the amount needed to adjust the ACL for management’s current estimate of expected credit losses. The Company’s ACL is calculated using collectively evaluated and individually evaluated loans. ​ ​ ​ The allowance for credit losses is measured on a collective pool basis when similar risk characteristics exist. Loans with similar risk characteristics are grouped into homogenous segments, or pools, for analysis. The Discounted Cash Flow (“DCF”) method is used for each loan in a pool, and the results are aggregated at the pool level. A probability of default and absolute loss given default are applied to a projective model of the loan’s cash flow while considering prepayment and principal curtailment effects. The analysis produces expected cash flows for each instrument in the pool by pairing loan-level term information (e.g., maturity date, payment amount, interest rate, etc.) with top-down pool assumptions (e.g., default rates and prepayment speeds). The Company has identified the following portfolio segments: Owner-Occupied Commercial Real Estate, Non-Owner Occupied Commercial Real Estate, Multifamily, Municipal, Commercial and Industrial, Commercial Construction and Land Development, Residential Construction, Residential Senior Mortgage, Residential Junior Mortgage, Revolving Mortgage, and Consumer and Other. ​ In determining the proper level of the ACL, management has determined that the loss experience of the Bank provides the best basis for its assessment of expected credit losses. The Company therefore used its own historical credit loss experience by each loan segment over an economic cycle, while excluding loss experience from certain acquired institutions (i.e., failed banks). For most of the segment models for collectively evaluated loans, the Company incorporated two or more macroeconomic drivers using a statistical regression modeling methodology. ​ Management considers forward-looking information in estimating expected credit losses. The Company subscribes to a third-party service which provides a quarterly macroeconomic baseline outlook and alternative scenarios for the United States economy. The baseline, along with the evaluation of alternative scenarios, is used by management to determine the best estimate within the range of expected credit losses. Management has evaluated the appropriateness of the reasonable and supportable forecast scenarios and has made adjustments as needed. For the contractual term that extends beyond the reasonable and supportable forecast period, the Company reverts to the long term mean of historical factors within four quarters using a straight-line approach. The Company generally uses a four-quarter forecast and a four-quarter reversion period. ​ Included in its systematic methodology to determine its ACL, management considers the need to qualitatively adjust expected credit losses for information not already captured in the loss estimation model. These qualitative adjustments either increase or decrease the quantitative model estimation (i.e., formulaic model results). Each period, the Company considers qualitative factors that are relevant within the qualitative framework that adhere to the Interagency Policy Statement on Allowances for Credit Losses. ​ When a loan no longer shares similar risk characteristics with its segment, the asset is assessed to determine whether it should be included in another pool or should be individually evaluated. The Company’s threshold for individually evaluated loans includes all non-accrual loans with a net book balance in excess of $1.0 million. Management will monitor the credit environment and make adjustments to this threshold in the future if warranted. Based on the threshold above, consumer financial assets will generally remain in pools unless they meet the dollar threshold. The expected credit losses on individually evaluated loans will be estimated based on discounted cash flow analysis unless the loan meets the criteria for use of the fair value of collateral, either by virtue of an expected foreclosure or through meeting the definition of collateral-dependent. Financial assets that have been individually evaluated can be returned to a pool for purposes of estimating the expected credit loss insofar as their credit profile improves and that the repayment terms were not considered to be unique to the asset. ​ Management measures expected credit losses over the contractual term of a loan. Effective January 1, 2023, the ACL includes expected losses on modifications of non-accrual loans over $1 million to borrowers experiencing financial difficulty estimated on an individual basis. Otherwise, a change to the ACL is not recorded upon modification because the effect of most modifications made to borrowers experiencing financial difficulty is already included in the allowance historical data. ​ ​ For purchased credit-deteriorated, otherwise referred to herein as PCD, assets are defined as acquired individual financial assets (or acquired groups of financial assets with similar risk characteristics) that, as of the date of acquisition, have experienced a more-than-insignificant deterioration in credit quality since origination, as determined by the Company’s assessment. The Company records acquired PCD loans by adding the expected credit losses (i.e., allowance for credit losses) to the purchase price of the financial assets rather than recording through the provision for credit losses in the income statement. The expected credit loss, as of the acquisition day, of a PCD loan is added to the allowance for credit losses. The non-credit discount or premium is the difference between the unpaid principal balance and the amortized cost basis as of the acquisition date. Subsequent to the acquisition date, the change in the ACL on PCD loans is recognized through the Provision for Credit Losses in the Consolidated Statements of Income. The non-credit discount or premium is accreted or amortized, respectively, into interest income over the remaining life of the PCD loan on a level-yield basis. ​ The Company follows its nonaccrual policy by reversing contractual interest income in the income statement when the Company places a loan on nonaccrual status. Therefore, management excludes the accrued interest receivable balance from the amortized cost basis in measuring expected credit losses on the portfolio and does not record an allowance for credit losses on accrued interest receivable. As of December 31, 2023 and December 31, 2022, the accrued interest receivables for loans recorded in Other Assets were $127.0 million and $105.4 million, respectively. ​ The Company has a variety of assets that have a component that qualifies as an off-balance sheet exposure. These primarily include undrawn portions of revolving lines of credit and standby letters of credit. The expected losses associated with these exposures within the unfunded portion of the expected credit loss will be recorded as a liability on the balance sheet. Management has determined that a majority of the Company’s off-balance sheet credit exposures are not unconditionally cancellable. Management completes funding studies based on historical data to estimate the percentage of unfunded loan commitments that will ultimately be funded to calculate the reserve for unfunded commitments. Management applies this funding rate, along with the loss factor rate determined for each pooled loan segment, to unfunded loan commitments, excluding unconditionally cancellable exposures and letters of credit, to arrive at the reserve for unfunded loan commitments. As of December 31, 2023 and December 31, 2022, the liability recorded for expected credit losses on unfunded commitments was $56.3 million and $67.2 million, respectively. The current adjustment to the ACL for unfunded commitments is recognized through the Provision for Credit Losses in the Consolidated Statements of Income. Other Real Estate Owned and Bank Property Held For Sale Other real estate owned (“OREO”) consists of properties obtained through foreclosure or through a deed in lieu of foreclosure in satisfaction of loans. The Company discloses former branch site assets as bank property held for sale and reports on a separate line on the Consolidated Balance Sheet. Both OREO and bank property held for sale are recorded at the lower of cost or fair value and the fair value was determined on the basis of current valuations obtained principally from independent sources, adjusted for estimated selling costs. At the time of foreclosure or initial possession of collateral, for OREO, any excess of the loan balance over the fair value of the real estate held as collateral is treated as a charge against the ACL. At the time a bank property is no longer in service and is moved to held for sale, any excess of the current book value over fair value is recorded as an expense in the Consolidated Statements of Income in the merger and branch consolidation related expense line item. The property is then actively marketed for sale at a price that is reasonable in relation to its current fair value. Subsequent adjustments to the value for those being held for sale are described in the following paragraph. ​ ​ ​ The Company reports subsequent declines in the fair value of OREO and bank properties held for sale below the new cost basis through valuation adjustments. Significant judgments and complex estimates are required in estimating the fair value of these properties, and the period of time within which such estimates can be considered current is significantly shortened during periods of market volatility. In response to market conditions and other economic factors, management may utilize liquidation sales as part of its problem asset disposition strategy. As a result of the significant judgments required in estimating fair value and the variables involved in different methods of disposition, the net proceeds realized from sales transactions could differ significantly from the current valuations used to determine the fair value of these properties. Management reviews the value of these properties periodically and adjusts the values as appropriate. Revenue and expenses from OREO operations, as well as gains or losses on sales and any subsequent adjustments to the value, are recorded as OREO Expense and Loan Related Expense, a component of Noninterest Expense in the Consolidated Statements of Income. Expenses related to bank property held for sale, as well as gains or losses on sales and any subsequent adjustments to the value, are recorded in Other Expenses, a component of Noninterest Expense in the Consolidated Statements of Income. B usiness Combinations and Method of Accounting for Loans Acquired The Company accounts for its acquisitions under FASB ASC Topic 805, Business Combinations, which requires the use of the acquisition method of accounting. All identifiable assets acquired, including loans, are recorded at fair value, which now requires us to record purchased financial assets with credit deterioration (PCD assets), defined as a more-than-insignificant deterioration in credit quality since origination or issuance, at the purchase price plus the allowance for credit losses expected at the time of acquisition. Under this method, there is no credit loss expense affecting net income on acquisition of PCD assets. Changes in estimates of expected credit losses after acquisition are recognized as provision for credit losses (or recovery for credit losses) in subsequent periods as they arise. Any non-credit discount or premium resulting from acquiring a pool of purchased financial assets with credit deterioration shall be allocated to each individual asset. At the acquisition date, the initial allowance for credit losses determined on a collective basis shall be allocated to individual assets to appropriately allocate any non-credit discount or premium. The non-credit discount or premium, after the adjustment for the allowance for credit losses, shall be accreted to interest income using the interest method based on the effective interest rate determined after the adjustment for credit losses at the adoption date. ​ A purchased financial asset that does not qualify as a PCD asset is accounted for similar to an originated financial asset. Generally, this means that an entity recognizes the allowance for credit losses for non-PCD assets through net income at the time of acquisition. In addition, both the credit discount and non-credit discount or premium resulting from acquiring a pool of purchased financial assets that do not qualify as PCD assets shall be allocated to each individual asset. This combined discount or premium shall be accreted to interest income using the effective yield method. ​ For further discussion of our loan accounting and acquisitions, see Note 2—Mergers and Acquisitions, Note 4—Loans and Note 5—Allowance for Credit Losses to the audited condensed consolidated financial statements. Premises and Equipment Land is carried at cost. Office equipment, furnishings, and buildings are carried at cost less accumulated depreciation computed principally on the declining-balance and straight-line methods over the estimated useful lives of the assets. Leasehold improvements are amortized on the straight-line method over the shorter of the estimated useful lives of the improvements or the terms of the related leases including lease renewals only when the Company is reasonably assured of the aggregate term of the lease. Additions to premises and equipment and major replacements are added to the accounts at cost. Maintenance and repairs and minor replacements are charged to expense when incurred. Gains and losses on routine dispositions are reflected in current operations. ​ Leases Right-of-Use (“ROU”) assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. We determined that we do not have any leases classified as finance leases, and that all of our leases are operating leases, with the exception of the two minor finance leases acquired through the merger with CenterState. ROU assets and liabilities for operating leases are recognized at commencement date based on present value of lease payments not yet paid, discounted using the discount rate for the lease at the lease commencement date over the lease term. For operating leases, lease expense is determined by the sum of the lease payments to be recognized on a straight-line basis over the lease term. ​ As of December 31, 2023 and 2022, we had operating ROU assets of $100.3 million and $108.0 million, respectively, recorded within Premises and Equipment on the Consolidated Balance Sheets and a lease liability of $108.3 million and $115.6 million, respectively, recorded within Other Liabilities on the Consolidated Balance Sheets. Bank Owned Life Insurance BOLI is comprised of long-term life insurance contracts on the lives of certain current and past employees where the insurance policy benefits and ownership are retained by the employer. Its cash surrender value is an asset that the Company uses to partially offset the future cost of employee benefits. The cash value accumulation on BOLI is permanently tax deferred if the policy is held to the insured person’s death and certain other conditions are met. Intangible Assets Intangible assets consist of goodwill, core deposit intangibles and client list intangibles that result from the acquisition of other banks or branches from other financial institutions. Core deposit intangibles represent the value of long-term deposit relationships acquired in these transactions. Client list intangibles represent the value of long-term client relationships for the wealth and trust management business. Goodwill represents the excess of the purchase price over the sum of the estimated fair values of the tangible and identifiable intangible assets acquired less the estimated fair value of the liabilities assumed in a business combination. At December 31, 2023 and December 31, 2022, the balance of goodwill was $1.9 billion. Goodwill has an indefinite useful life and is evaluated for impairment annually or more frequently if events and circumstances indicate that the asset might be impaired. An impairment loss is recognized to the extent that the carrying amount exceeds the asset’s fair value. ​ ASU No. 2017-04 simplifies the accounting for goodwill impairment for all entities by requiring impairment charges to be based on Step 1 of the previous accounting guidance’s two-step impairment test under ASC Topic 350. Under this guidance, if a reporting unit’s carrying amount exceeds its fair value, an entity will record an impairment charge based on that difference. The impairment charge will be limited to the amount of goodwill allocated to that reporting unit. The standard eliminates the requirement to calculate a goodwill impairment charge using Step 2 which involved calculating an implied fair value of goodwill for each reporting unit for which the first step indicated impairment. The standard does not change the guidance on completing Step 1 of the goodwill impairment test. An entity will still be able to perform today’s optional qualitative goodwill impairment assessment before determining whether to proceed to the quantitative step of determining whether the reporting unit’s carrying amount exceeds it fair value. ​ The Company evaluated the carrying value of goodwill as of October 31, 2023, our annual test date, considering the effects of the bank failures in early 2023 and other market conditions and determined that no impairment charge was necessary. ​ ​ Core deposit intangibles and client list intangibles consist primarily of amortizing assets established during the acquisition of other banks. This includes whole bank acquisitions and the acquisition of certain assets and liabilities from other financial institutions. Core deposit intangibles, included in Core Deposit and Other Intangibles in the Consolidated Balance Sheets, are amortized over the estimated useful lives of the deposit accounts acquired (generally 10 to 13 years) on an accelerated basis method which reasonably approximates the anticipated benefit stream from the accounts. The estimated useful lives are periodically reviewed for by comparing current balances to the initial estimates calculated at the time of merger or acquisition. Client list intangibles, included in Core Deposit and Other Intangibles in the Consolidated Balance Sheets, are amortized over the estimated useful lives of the client lists acquired (generally 15 years) on the straight-line method. The estimated useful lives are periodically reviewed for reasonableness. Mortgage Servicing Rights (“MSRs”) The Company has a mortgage loan servicing portfolio with related mortgage servicing rights. MSRs represent the present value of the future net servicing fees from servicing mortgage loans. Servicing assets and servicing liabilities must be initially measured at fair value, if practicable. For subsequent measurements, an entity can choose to measure servicing assets and liabilities either based on fair value or lower of cost or market. The Company uses the fair value measurement option for MSRs. The methodology used to determine the fair value of MSRs is subjective and requires the development of a number of assumptions, including anticipated prepayments of loan principal. Fair value is determined by estimating the present value of the asset’s future cash flows utilizing estimated market-based prepayment rates and discount rates, interest rates and other economic factors and assumptions validated through comparison to trade information, industry surveys and with the use of independent third-party appraisals. Risks inherent in the MSRs valuation include higher than expected prepayment rates and/or delayed receipt of cash flows. The value of MSRs is significantly affected by interest rates available in the marketplace, which influence loan prepayment speeds. In general, during periods of declining interest rates, the value of mortgage servicing rights declines due to increasing prepayments attributable to increased mortgage refinance activity. Conversely, during periods of rising interest rates, the value of servicing rights generally increases due to reduced refinance activity. MSRs are carried at fair value with changes in fair value recorded as a component of Mortgage Banking Income. Transfer of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over the transferred assets is deemed to be surrendered when: (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. The Company reviews all sales of loans by evaluating specific terms in the sales documents and believes that the criteria discussed above to qualify for sales treatment have been met as loans have been transferred for cash and the notes and mortgages for all loans in each sale are endorsed and assigned to the transferee. Investors perform quality control reviews of mortgage loans purchased including post-purchase, early payment default, servicing, and post-foreclosure reviews. If a loan level deficiency cannot be remedied and breaches a term contained in the Investor agreement in effect at the time of loan delivery, the reviews may result in loan repurchase demands, or other alternative remedies. In certain sales, mortgage servicing rights may be retained and in other programs potential loss exposure from the credit enhancement obligation may be retained, both of which are evaluated and appropriately measured at the date of sale. ​ The Company maintains a risk management program to manage interest rate risk and pricing risk associated with its mortgage lending activities. This program includes the use of forward contracts and other derivatives that are used to offset changes in value of the mortgage inventory due to changes in market interest rates. Forward contracts to sell primarily fixed-rate mortgage loans are entered into to reduce the exposure to market risk arising from potential changes in interest rates. This could affect the fair value of mortgage loans held for sale and outstanding interest rate lock commitments which guarantee a certain interest rate if the loan is ultimately funded by the Company as a mortgage loan held for sale. The commitments to sell mortgage loans are at fixed prices and are schedule to settle on specific dates. ​ ​ ​ The Company enters into interest rate lock commitments for residential mortgage loans which commits it to lend funds to a potential borrower at a specific interest rate and within a specified time period. Interest rate lock commitments that relate to origination of mortgage loans that, if originated, will be held for sale, are considered derivative financial instruments under applicable accounting guidance. Outstanding interest rate lock commitments expose the Company to the risk that the price of the mortgage loans underlying the commitments may decline due to increases in mortgage interest rates from the inception of the rate lock to the funding of the loan and the eventual commitment for sale into the secondary market. ​ The Company packages the fixed rate conforming mortgage loans to be sold to investors. The Company records the sale when the transferred loans are purchased by the investor and the accounting criteria for the sale are met. Gains or losses recorded depend in part on the net carrying amount of the loans sold, which is allocated between the loans sold and retained interests based on their relative fair values at the date of sale. Since quoted market prices are not typically available, the fair value of retained interests is estimated through the services of a third-party service provider to determine the net present value of expected future cash flows. Such models incorporate management’s best estimates of key variables, such as prepayment speeds and discount rates that would be used by market participants and are appropriate for the risks involved. The Company generally retains mortgage servicing rights on residential loans sold in the secondary market to Fannie Mae and Freddie Mac. Loans sold to other third-party investors are sold servicing released. Gains and losses incurred on loans sold to third-party investors are included in Mortgage Banking Income in the Consolidated Statements of Income. Revenue from Contracts with Customers The majority of our revenue is derived primarily from interest income from receivables (loans) and securities. Other revenues are derived from fees received in connection with deposit accounts, mortgage banking activities including gains from the sale of loans and loan origination fees, correspondent banking activities including revenue from the sale of fixed income securities and fees from hedging services, and trust and investment advisory services. We recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ​ We report network costs associated with debit card and ATM transactions netted against the related fees from such transactions. For years 2023, 2022, and 2021, gross interchange and debit card transaction fees totaled $41.3 million, $40.7 million, and $38.3 million, respectively, while related network costs totaled $20.7 million, $18.5 million, and $20.3 million, respectively. On a net basis, the Company reported $20.6 million, $22.2 million, and $18.0 million, respectively, as interchange and debit card transactions fees in the accompanying Consolidated Statements of Income within Noninterest Income for the years ended December 31, 2023, 2022, and 2021. ​ The Company maintains contracts to provide services, primarily for investment advisory and/or custody of assets. Through the Company’s wholly owned subsidiaries, the Bank, and SouthState Advisory, Inc., the Company contracts with its customers to perform IRA, Trust, and/or Custody and Agency advisory services. Total revenue recognized from these contracts with customers was $39.4 million, $39.0 million, and $37.0 million, respectively, for the years ended December 31, 2023, 2022 and 2021. The Bank has contracts with its customers to perform deposit account services. Total revenue recognized from these contracts with customers is $134.6 million, $129.7 million, and $107.3 million, respectively, for the years ended December 31, 2023, 2022 and 2021. Due to the nature of our relationship with the customers that we provide services, we do not incur costs to obtain contracts and there are no material incremental costs to fulfill these contracts that should be capitalized. ​ Disaggregation of Revenue - The portfolio of services provided to the Company’s customers which generates revenue for which the revenue recognition standard applies consists of approximately 1.1 million active contracts at December 31, 2023. The Company has disaggregated revenue according to the timing of the transfer of service. Total revenue derived from contracts in which services are transferred at a point in time was $237.3 million, $266.8 million, and $255.4 million, respectively, for the years ended December 31, 2023, 2022 and 2021. Total revenue derived from contracts in which services are transferred over time was $20.9 million, $20.2 million, and $19.9 million, respectively, for the years ended December 31, 2023, 2022 and 2021. Revenue is recognized as the services are provided to the customers. Economic factors impacting the customers could affect the nature, amount, and timing of these cash flows, as unfavorable economic conditions could impair the customers’ ability to provide payment for services. This risk is mitigated as we generally deduct payments from customers’ accounts as services are rendered. ​ Contract Balances - The timing of revenue recognition, billings, and cash collections results in billed accounts receivable on our balance sheet. Most contracts call for payment by a charge or deduction to the respective customer account but there are some that require a receipt of payment from the customer. For fee per transaction contracts, the customers are billed as the transactions are processed. For hourly rate and monthly service contracts related to trust and some investment revenues, the customers are billed monthly (generally as a percentage basis point of the market value of the investment account). In some cases, specific to SouthState Advisory, Inc., customers are billed in advance for quarterly services to be performed based on the past quarter’s average account balance. These do create contract liabilities or deferred revenue, as the customers pay in advance for service. Neither the contract liabilities nor the accounts receivables balances are material to the Company’s Consolidated Balance Sheets. ​ Performance Obligations - A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account for revenue recognition. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. The performance obligations for these contracts are satisfied as the service is provided to the customer (either over time or at a point in time). The payment terms of the contracts are typically based on a basis point percentage of the investment account market value, fee per hour of service, or fee for service incurred. There are no significant financing components in the contracts. Excluding deposit services revenues, which are mostly billed at a point in time as a fee for services incurred, all other contracts contain variable consideration in that fees earned are derived from market values of accounts or from hours worked for services performed which determines the amount of consideration to which we are entitled. The variability is resolved when the hours are incurred or services are provided. The contracts do not include obligations for returns, refunds, or warranties. The contracts are specific to the amounts owed to the Company for services performed during a period should the contracts be terminated. ​ Significant Judgments - All of the contracts create performance obligations that are satisfied at a point in time excluding the contracts billed in advance through SouthState Advisory, Inc. and some immaterial deposit revenues. Revenue is recognized as services are billed to the customers. Variable consideration does exist for contracts related to our trust and investment services as revenues are based on market values and services performed. The Company has adopted the right-to-invoice practical expedient for trust management contracts through SouthState Bank, which we contract with our customers to perform IRA, Trust, and/or Custody services. Advertising Costs The Company expenses advertising costs as they are incurred and advertising communication costs the first time the advertising takes place. The Company may establish accruals for anticipated advertising expenses within the course of a fiscal year. Comprehensive Income (Loss) Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Certain changes in assets and liabilities, such as (1) unrealized gains and losses on available for sale securities (2) unrealized gains and losses on effective portions of derivative financial instruments accounted for as cash flow hedges and (3) net change in unrecognized amounts related to pension and post-retirement benefits, are reported as a separate component of the equity section of the Consolidated Balance Sheets. Such items, along with net income, are components of total comprehensive (loss) income (see Consolidated Statements of Comprehensive Income (Loss) on page F-8). Employee Benefit Plans The Company’s post retirement plans are accounted for in accordance with FASB ASC 715, Compensation—Retirement Benefits, which requires the Company to recognize the funded status in its statement of financial position. See Note 18—Post-Retirement Benefits for information regarding our post-retirement benefit plans. The expected costs of the post retirement benefit plans are expensed over the period that employees provide service. ​ ​ The Employee Stock Purchase Plan (“ESPP”) allows for a look-back option which establishes the purchase price as an amount based on the lesser of the stock’s market price at the grant date or its market price at the exercise (or purchase) date. For the shares issued in exchange for employee services under the plan, the Company accounts for the plan under the FASB ASC 718, Compensation—Stock Compensation, in which the fair value measurement method is used to estimate the fair value of the equity instruments, based on the share price and other measurement assumptions at the grant date. See Note 19—Share-Based Compensation for the amount the Company recognized as expense for the years ended December 31, 2023, 2022 and 2021. Income Taxes Income taxes are provided for the tax effects of the transactions reported in the accompanying consolidated financial statements and consist of taxes currently due plus deferred taxes related primarily to differences between the tax basis and financial statement. The deferred tax assets and liabilities represent the future tax return consequences of those differences, which will either be taxable or deductible when the assets and liabilities are recovered or settled. Deferred tax assets and liabilities are reflected at income tax rates applicable to the period in which the deferred tax assets or liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the Provision for Income Taxes in the Consolidated Statements of Income. The Company will evaluate and recognize income tax benefits related to any uncertain tax positions using the recognition and measurement thresholds outlined in the applicable guidance. If the Company does not believe that it is more likely than not that an uncertain tax position will be sustained, the Company records a liability for the uncertain tax positions. If a tax benefit is more-likely-than not of being sustained based on the applicable authority, the Company records an income tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement with a taxing authority. The Company recognizes interest and penalties related to unrecognized tax benefits on other expense line in the accompanying consolidated statements of income. Accrued interest and penalties are included on the related liability lines in the consolidated balance sheet. ​ See Note 12—Income Taxes to the consolidated financial statements for further details and discussion. Earnings Per Share Basic earnings per share (“EPS”) represents income available to common shareholders divided by the weighted-average number of shares outstanding during the year. Diluted earnings per share reflects additional shares that would have been outstanding if dilutive potential shares had been issued. Potential shares that may be issued by the Company relate solely to outstanding stock options, restricted stock and restricted stock units (non-vested shares and vested shares subject to a holding period), and are determined using the treasury stock method. Under the treasury stock method, the number of incremental shares is determined by assuming the issuance of stock for the outstanding stock options, reduced by the number of shares assumed to be repurchased from the issuance proceeds, using the average market price for the year of the Company’s stock. Weighted-average shares for the basic and diluted EPS calculations have been reduced by the average number of unvested restricted shares. Derivative Financial Instruments The Company’s interest rate risk management strategy incorporates the use of derivative financial instruments. Historically, the Company has used interest rate swaps to essentially convert a portion of its variable-rate debt to a fixed rate. Cash flows related to variable-rate debt will fluctuate with changes in an underlying rate index. When effectively hedged, the increases or decreases in cash flows related to the variable-rate debt will generally be offset by changes in cash flows of the derivative instrument designated as a hedge. This strategy is referred to as a cash flow hedge. For derivatives designated as hedging exposure to variable cash flows of a forecasted transaction (cash flow hedge), the derivative’s entire unrealized gain or loss is initially reported as a component of other comprehensive income and subsequently reclassified into earnings when the forecasted transaction affects earnings or when the hedged instrument and related swap are terminated before maturity. For derivatives that are not designated as hedging instruments, changes in the fair value of the derivatives are recognized in earnings immediately. The Company did not use cash flow hedges for the years ended December 31, 2023 or December 31, 2022. ​ ​ The Company maintains loan swaps which are accounted for as a fair value hedge. This derivative protects the Company from interest rate risk caused by changes in the SOFR curve in relation to a certain designated fixed rate loan. Fair value hedges convert the fixed rate to a floating rate. For discussion related to Reference Rate Reform, please refer to the caption “Accounting Standards Adopted” within this Note 1—Summary of Significant Accounting Policies. ​ The Company’s risk management strategy for its mortgage banking activities incorporates derivative instruments used to economically hedge both the value of the mortgage servicing rights and the mortgage pipeline. These derivative instruments are not designated as hedges and are not speculative in nature. The derivative instruments that are used to hedge the value of the mortgage servicing rights include financial forwards, futures contracts, and options written and purchased. When-issued securities and mandatory cash forward trades are typically used to hedge the mortgage pipeline. These instruments derive their cash flows, and therefore their values, by reference to an underlying instrument, index or referenced interest rate. ​ During 2023, management began executing a series of short-term interest rate hedges to address monthly accrual mismatches related to the Company’s Assumable Rate Conversion (“ARC”) program and its transition from LIBOR to SOFR after June 30, 2023. The Company is required to execute the correspondent side of its back-to-back swaps with customers with the central clearinghouses, London Clearing House (“LCH”) and Chicago Mercantile Exchange (“CME”). Term SOFR was not available to execute through CME and LCH, and therefore, management elected to convert to the CME-eligible daily SOFR. Because many of the respondent bank customers converted to term SOFR, this created interest rate basis risk. To address this risk, monthly interest rate hedges were executed to minimize the impact of accrual mismatches between the monthly term SOFR used by the customer and the daily SOFR rates used by the central clearinghouses. As these economic interest rate hedges do not meet the strict hedge accounting requirements, changes in the fair value of the swaps are recognized directly in earnings. ​ The Company’s risk management strategy also incorporates the use of interest rate swap contracts that help in managing interest rate risk within the loan portfolio and foreign currency exchange. These derivatives are not designated as hedges and are not speculative, and result from a service the Company provides to certain customers. The Company executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously economically hedged by offsetting interest rate swaps that the Company executes with a third-party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. ​ The Company determined the variation margin payments for the Company’s interest rate swaps centrally cleared through LCH and CME meet the legal characteristics of daily settlements of the derivatives (settle-to-market) rather than collateral (collateralize-to-market). As a result, the variation margin payment and the related derivative instruments are considered a single unit of account for accounting and financial reporting purposes. Depending on the net position, the fair value of the single unit of account is reported in Derivative Assets or Derivative Liabilities on the Consolidated Balance Sheets, as opposed to interest-earning deposits (restricted cash) within Cash and Cash Equivalents or interest-bearing deposits within Total Deposits. In addition, the expense or income attributable to the variation margin payments for the centrally cleared swaps is reported in Noninterest Income, specifically within Correspondent and Capital Markets Income, as opposed to Interest Income or Interest Expense. The daily settlement of the derivative exposure does not change or reset the contractual terms of the instrument. ​ By using derivative instruments, the Company is exposed to credit and market risk. If the counterparty fails to perform, credit risk is equal to the fair value gain in a derivative. When the fair value of a derivative contract is positive, this situation generally indicates that the counterparty is obligated to pay the Company, and, therefore, creates a repayment risk for the Company. When the fair value of a derivative contract is negative, the Company is obligated to pay the counterparty and, therefore, has no repayment risk. The Company minimizes the credit risk in derivative instruments by entering into transactions with high-quality counterparties that are reviewed periodically by the Company. ​ ​ The Company’s derivative activities are monitored by its Asset-Liability Management Committee (“ALCO”) as part of that committee’s oversight of the Company’s asset/liability and treasury functions. The Company’s ALCO is responsible for implementing various hedging strategies that are developed through its analysis of data from financial simulation models and other internal and industry sources. The resulting hedging strategies are then incorporated into the overall interest-rate risk management process. ​ The Company recognizes the fair value of derivatives as assets or liabilities in the financial statements. The accounting for the changes in the fair value of a derivative depends on the intended use of the derivative instrument at inception. The change in fair value of the effective portion of cash flow hedges is accounted for in Other Comprehensive Income rather than Net Income. Gains and losses recognized from changes in fair value on derivatives are reported in Derivative Assets and Derivatives Liabilities lines under cash flows from operating activities section in the Consolidated Statements of Cash Flows. Changes in fair value of derivative instruments that are not intended as a hedge are accounted for in Net Income in the period of the change. See Note 28—Derivative Financial Instruments for further disclosure. Reclassification Certain amounts previously reported have been reclassified to conform to the current year’s presentation. Such reclassifications are immaterial and had no effect on net income, comprehensive income (loss), total assets or total shareholders’ equity as previously reported. Recent Accounting and Regulatory Pronouncements Accounting Standards Adopted In March 2022, FASB issued ASU No. 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. The amendments in this ASU eliminate the long-standing accounting guidance for Troubled Debt Restructurings (“TDRs”) by creditors in Subtopic 310-40, Receivables – Troubled Debt Restructurings by Creditors, as it is no longer meaningful due to the introduction of Topic 326, which requires an entity to consider lifetime expected credit losses on loans when establishing an allowance for credit losses. Thus, most losses that would have been realized for a TDR under Subtopic 310-40 are now captured by the accounting required under Topic 326. The amendments in this ASU also require that an entity disclose current-period gross write 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 Company adopted ASU No. 2022-02 effective January 1, 2023. We elected to apply a prospective transition method, which applies only to modifications occurring after the adoption date. For loans meeting the Bank’s materiality criteria, which includes loans in excess of $250,000, an assessment of whether a borrower is experiencing financial difficulty is made on the date of the modification. On the transition date, the former TDR loans as of December 31, 2022 were designated as individually evaluated loans on January 1, 2023 and retained the allowance for credit losses allocated to these loans at the adoption date as the credit risk of these loans did not change. Aside from the changes to the disclosures required by ASU No. 2022-02, the ASU did not have a material impact on our consolidated financial statements. In March 2020, FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848 – Facilitation of the Effects of Reference Rate Reform on Financial Reporting and subsequently expanded the scope of ASU No. 2020-04 with the issuance of ASU No. 2021-01 and extended the sunset date to December 31, 2024 with ASU No. 2022-06. This update provides companies with optional guidance to ease the potential accounting burden associated with transitioning away from reference rates that will be discontinued. The amendments in this update provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. 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. The amendments in this update were effective for all entities as of March 12, 2020 and may be applied through December 31, 2022. In January 2021, the FASB issued ASU 2021-01 which 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. ASU 2022-06 extended the effective date through December 31, 2024. The amendments are effective as of March 12, 2020 through December 31, 2024 and can be adopted at the instrument level on an ongoing basis. Management adopted these optional expedients beginning April 1, 2023 to coincide with the transition and modification of our LIBOR-exposed instruments. Most of the loan modifications met the requirements of these practical expedients, as most were subject to the Adjustable Interest Rate (LIBOR) Act which permits a replacement index with a spread adjustment. These modifications did not have a material impact on the consolidated financial statements. Issued But Not Yet Adopted Accounting Standards In March 2023, FASB issued ASU No. 2023-02, Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. The Proportional Amortization method was introduced by ASU No. 2014-01, but limited this amortization method to investments in low-income housing tax credit structures. The amendments in ASU 2023-02 will allow entities the option to elect whether they account for tax equity investments using the proportional amortization method if certain conditions are met, regardless of the program from which the income tax credits are received. The election would be on a program-by-program basis. The ASU would also require disclosures to be transparent about an entity’s investments that generate income tax credits and other income tax benefits. The amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years with early adoption permitted. The Company maintains investments in low-income housing tax structures and has elected to apply the proportional amortization method for its low-income housing tax credits effective January 1, 2024 and will apply the changes to the accounting treatment under the modified retrospective method. The Company estimates it will record a cumulative adjustment to retained earnings of approximately $10 million as a result of the adoption of ASU No. 2023-02. ​ In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, to improve disclosures about a public entity’s reportable segments and address requests from investors and other allocators of capital for additional, more detailed information about a reportable segment’s expenses. Segment information gives investors an understanding of overall performance and is key to assessing potential future cash flows. In addition, although information about a segment’s revenue and measure of profit or loss is disclosed in an entity’s financial statements, there is limited information disclosed about a segment’s expenses. The key amendments include annual and interim disclosures of significant expenses and other segment items that are regularly provided to the chief operating decision maker and included within each reported measure of profit or loss, as well as any other key measure of performance used for segment management decisions. This ASU also requires disclosure of key profitability measures used in assessing performance and how to allocate resources. The amendments in this ASU are effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company does not anticipate this ASU will have a material impact on its financial statements. ​ In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which aims to address requests for improved income tax disclosures from investors, lenders, creditors and other allocators of capital (collectively, “investors”) that use the financial statements to make capital allocation decisions. The amendments in this ASU address investor requests for more transparency about income tax information, including jurisdictional information, by requiring consistent categories and greater disaggregation of information in both the rate reconciliation and income taxes paid disaggregated by jurisdiction. The amendments are effective for annual periods beginning after December 15, 2024. The Company does not anticipate this ASU will have a material impact on its financial statements.
