Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION	NOTE 1 — SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION Nature of Operations First Citizens BancShares, Inc. (the “Parent Company” and, when including all of its subsidiaries on a consolidated basis, “we,” “us,” “our,” “BancShares”) is a financial holding company organized under the laws of Delaware that conducts operations through its banking subsidiary, First-Citizens Bank & Trust Company (“FCB”), which is headquartered in Raleigh, North Carolina. BancShares and its subsidiaries operate a network of branches and offices, predominantly located in the Southeast, Mid-Atlantic, Midwest and Western United States. BancShares provides various types of commercial and consumer banking services, including lending, leasing, and wealth management services. Deposit services include checking, savings, money market, and time deposit accounts. Business Combinations BancShares accounts for business combinations using the acquisition method of accounting. Under this method, acquired assets and assumed liabilities are included with the acquirer’s accounts at their estimated fair value as of the date of acquisition, with any excess of purchase price over the fair values of the net assets acquired and any finite-lived intangible assets established in connection with the business combination recognized as goodwill. To the extent the fair value of identifiable net assets acquired exceeds the purchase price, a gain on acquisition is recognized. Acquisition-related costs are recognized as period expenses as incurred. On March 27, 2023 (the “SVBB Acquisition Date”), FCB acquired substantially all loans and certain other assets and assumed all customer deposits and certain other liabilities of Silicon Valley Bridge Bank, N.A. (“SVBB”) from the Federal Deposit Insurance Corporation (the “FDIC”) pursuant to the terms of a purchase and assumption agreement (the “SVBB Purchase Agreement”) by and among FCB, the FDIC, and the FDIC, as receiver of SVBB (the “SVBB Acquisition”). Refer to Note 2—Business Combinations for additional information. BASIS OF PRESENTATION Principles of Consolidation and Basis of Presentation These consolidated financial statements and notes thereto are presented in accordance with instructions for Form 10-Q and Article 10 of Regulation S-X and, therefore, do not include all information and notes necessary for a complete presentation of financial position, results of operations and cash flow activity required in accordance with accounting principles generally accepted in the United States of America (“GAAP”). In the opinion of management, all normal recurring adjustments necessary for a fair presentation of the consolidated financial position and consolidated results of operations have been made. The unaudited interim consolidated financial statements included in this Quarterly Report on Form 10-Q (this “Form 10-Q”) should be read in conjunction with the Consolidated Financial Statements and Notes to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2023 (“2023 Form 10-K”). Interim results are not necessarily indicative of results for a full year. The consolidated financial statements of BancShares include the accounts of BancShares and its subsidiaries, certain partnership interests and variable interest entities (“VIEs”) where BancShares is the primary beneficiary, if applicable. All significant intercompany accounts and transactions are eliminated upon consolidation. Assets held in agency or fiduciary capacity are not included in the consolidated financial statements. See Note 8—Variable Interest Entities and Note 9—Other Assets for additional information. Reclassifications Financial Statements In certain instances, amounts reported in the 2023 consolidated financial statements have been reclassified to conform to the current financial statement presentation. Such reclassifications had no effect on previously reported stockholders’ equity or net income. Reportable Segments At December 31, 2023, BancShares reported its financial results in the General Bank, Commercial Bank, Silicon Valley Bank (“SVB”), and Rail segments. All other financial information was included in the “Corporate” section of the segment disclosures. We made the following changes to our segment reporting during the first quarter of 2024: • the private banking and wealth management components of the SVB segment were integrated into the General Bank segment which already included other wealth management activities; • the SVB segment was renamed SVB Commercial as its customers primarily include commercial clients in key innovation markets, as well as private equity and venture capital clients; and • the Direct Bank (a nationwide digital banking platform that delivers deposit products to consumers) previously allocated to the General Bank segment was transitioned to Corporate which already included borrowings and brokered deposits. Segment disclosures for 2023 periods included in this Form 10-Q were recast to reflect the segment reporting changes summarized above. Refer to Note 20—Business Segment Information for additional information. Loan Classes At December 31, 2023, our disclosures for loans and leases and the allowance for loan and lease losses (“ALLL”) were aggregated into Commercial, Consumer, and SVB portfolios, each of which consisted of several loan classes. The SVB portfolio consisted of the following loan classes: global fund banking, investor dependent - early stage, investor dependent - growth stage, innovation Commercial and Industrial (“innovation C&I”) and cash flow dependent, private bank, commercial real estate (“CRE”), and “other.” For further information, refer to Note 1—Significant Accounting Policies and Basis of Presentation in the Notes to the Consolidated Financial Statements included in our 2023 Form 10-K. During the first quarter of 2024, the private bank, CRE, and “other” loan classes described below, which were mapped to the SVB portfolio at December 31, 2023, were remapped to the applicable loan classes within the Commercial and Consumer portfolios. • The private bank loan class included loans to clients who are primarily private equity or venture capital professionals and executives in the innovation companies, as well as high net worth clients. This loan class included mortgages, home equity lines of credit, restricted and private stock loans, personal capital call lines of credit, lines of credit against liquid assets, and other secured and unsecured lending products. In addition, this class included owner occupied commercial mortgages and real estate secured loans. • The CRE loan class consisted generally of acquisition financing loans for commercial properties including office buildings, retail properties, apartment buildings and industrial/warehouse space. • The “other” loan class included smaller acquired portfolios, such as commercial and industrial, premium wine, and other acquired portfolios. Certain loans secured by other nonfarm, nonresidential properties, which were mapped to the owner occupied commercial mortgage loan class at December 31, 2023, were remapped to the non-owner occupied commercial mortgage loan class during the first quarter of 2024. Loan and lease and ALLL disclosures for 2023 periods included in this Form 10-Q were recast to reflect the changes in loan classes summarized above. Refer to Note 4—Loans and Leases and Note 5—Allowance for Loan and Lease Losses. Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions based on available information. These estimates and assumptions impact the amounts reported in the consolidated financial statements and accompanying notes and the disclosures provided, and actual results could differ from those estimates. The significant estimate related to the determination of the ALLL is considered a critical accounting estimate. SIGNIFICANT ACCOUNTING POLICIES Significant accounting policies are described in the 2023 Form 10-K. Relevant updates to the significant accounting policies are described below. Newly Adopted Accounting Standards As of January 1, 2024, BancShares adopted the following Accounting Standards Updates (“ASUs”) issued by the Financial Accounting Standards Board (“FASB”): ASU 2023-02 – Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method, Issued March 2023 The amendments in this ASU allow entities to elect to account for qualifying tax equity investments using the proportional amortization method (“PAM”), regardless of the program giving rise to the related income tax credits. PAM accounting had been available only for qualifying investments in qualified affordable housing projects. This ASU also requires disclosure of the nature of the investor’s tax equity investments and the effect of income tax credits and other income tax benefits from tax equity investments on the investor’s balance sheet and income statement. These required disclosures are included in Note 8—Variable Interest Entities. Adoption of this ASU did not have a material impact on our consolidated financial statements or disclosures. ASU 2022-03 – Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, Issued June 2022 The amendments in this ASU clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. This ASU also requires specific disclosures for equity securities subject to contractual sale restrictions. Adoption of this ASU did not have a material impact on our consolidated financial statements or disclosures.

Business Combination and Asset Acquisition [Abstract]
BUSINESS COMBINATIONS	NOTE 2 — BUSINESS COMBINATIONS Silicon Valley Bridge Bank Acquisition FCB completed the SVBB Acquisition on the SVBB Acquisition Date and acquired substantially all loans and certain other assets and assumed all customer deposits and certain other liabilities of SVBB in an FDIC-assisted transaction. BancShares determined that the SVBB Acquisition constitutes a business combination as defined by Accounting Standards Codification (“ASC”) Topic 805, Business Combinations . Accordingly, the assets acquired and liabilities assumed are presented at their estimated fair values based on valuations as of March 27, 2023. The determination of estimated fair values required management to make certain estimates about discount rates, future expected cash flows, market conditions at the time of the SVBB Acquisition and other future events that are highly subjective in nature. Management has finalized its fair value estimates for the acquired assets and assumed liabilities. The final fair value estimates included adjustments for information relating to events or circumstances existing at the SVBB Acquisition Date that impacted the preliminary fair value estimates within the allowable period not to exceed one year following the SVBB Acquisition Date (“Measurement Period Adjustments”). We recorded Measurement Period Adjustments during 2023. There were no Measurement Period Adjustments during the three months ended March 31, 2024. Pursuant to the terms of the SVBB Purchase Agreement, FCB acquired assets with a total fair value of approximately $107.54 billion as of the SVBB Acquisition Date, primarily including $68.47 billion of loans, net of the initial ALLL for purchased credit deteriorated (“PCD”) loans, and $35.31 billion of cash and interest-earning deposits at banks. FCB also assumed liabilities with a total fair value of approximately $61.42 billion, primarily including $56.01 billion of customer deposits. The deposits were acquired without a premium and the assets were acquired at a discount of approximately $16.45 billion pursuant to the terms of the SVBB Purchase Agreement. Further details regarding the fair values of the acquired assets and assumed liabilities are provided in the “Fair Value Purchase Price Allocation” table below. In connection with the SVBB Purchase Agreement, FCB also entered into a commercial shared loss agreement with the FDIC (the “Shared-Loss Agreement”). The Shared-Loss Agreement covered an estimated $60 billion of commercial loans (collectively, the “Covered Assets”) at the time of acquisition. The FDIC will reimburse FCB for 0% of losses of up to $5 billion with respect to Covered Assets and 50% of losses in excess of $5 billion with respect to Covered Assets (“FDIC Loss Sharing”) and FCB will reimburse the FDIC for 50% of recoveries related to such Covered Assets (“FCB reimbursement”). The Shared-Loss Agreement provides for FDIC Loss Sharing for five years and FCB reimbursement for eight years. The Shared-Loss Agreement extends to loans funded within one year of the SVBB Acquisition Date that were unfunded commitments to loans at the SVBB Acquisition Date. If certain conditions are met pursuant to the Shared-Loss Agreement, FCB has agreed to pay to the FDIC, 45 days after March 31, 2031 (or, if earlier, the time of disposition of all acquired assets pursuant to the Shared-Loss Agreement), a true-up amount up to $1.5 billion calculated using a formula set forth in the Shared-Loss Agreement. As noted below, preliminary estimates indicate there is no material value to attribute to the loss indemnification asset or true-up liability. In connection with the SVBB Acquisition, FCB issued a five Purchase Price Consideration for the SVBB Acquisition As consideration for the SVBB Acquisition, FCB issued the Purchase Money Note with a principal amount of $36.07 billion (fair value of $35.81 billion). FCB pledged specified assets as collateral security for the Purchase Money Note and the Advance Facility Agreement, including loans purchased from the FDIC as receiver to SVBB, the related loan documents and collections, accounts established for collections and disbursements, any items credited thereto, such additional collateral (if any) as the parties may agree to in the future, and proceeds thereof. The interest rate on the Purchase Money Note accrues at a rate of 3.50% per annum. There are no scheduled principal payments under the Purchase Money Note. FCB may voluntarily prepay principal under the Purchase Money Note without premium or penalty, twice per month. The principal amount of the Purchase Money Note is based on the carrying value of net assets acquired less the asset discount of $16.45 billion pursuant to the terms of the SVBB Purchase Agreement. In addition, as part of the consideration for the SVBB Acquisition, BancShares issued a Cash Settled Value Appreciation Instrument to the FDIC (the “Value Appreciation Instrument”) in which FCB agreed to make a cash payment to the FDIC equal to the product of (i) 5 million and (ii) the excess amount by which the average volume weighted price of one share of Class A common stock, over the two The following table provides the final purchase price allocation, including Measurement Period Adjustments, to the identifiable assets acquired and liabilities assumed at their estimated fair values as of the SVBB Acquisition Date. Fair Value Purchase Price Allocation dollars in millions Fair Value Purchase Price Allocation as of March 27, 2023 Purchase price consideration Purchase Money Note (1) $ 35,808 Value Appreciation Instrument 500 Purchase price consideration $ 36,308 Assets Cash and due from banks $ 1,310 Interest-earning deposits at banks 34,001 Investment securities available for sale 385 Loans and leases, net of the initial PCD ALLL 68,468 Affordable housing tax credit and other unconsolidated investments 1,273 Premises and equipment 308 Core deposit intangibles 230 Other assets 1,564 Total assets acquired $ 107,539 Liabilities Deposits $ 56,014 Borrowings 10 Deferred tax liabilities 3,364 Other liabilities 2,035 Total liabilities assumed $ 61,423 Fair value of net assets acquired 46,116 Gain on acquisition, after income taxes (2) (3) $ 9,808 Gain on acquisition, before income taxes (2) $ 13,172 (1) The principal amount of the Purchase Money Note is the carrying value of net assets acquired of approximately $52.52 billion less the asset discount of $16.45 billion pursuant to the SVBB Purchase Agreement. The $35.81 billion above is net of a fair value discount of approximately $264 million. (2) The difference between the gain on acquisition before and after taxes reflects the deferred tax liabilities recorded in the SVBB Acquisition. (3) The $9.81 billion gain on acquisition includes Measurement Period Adjustments, whereas the $9.82 billion gain on acquisition in the Consolidated Statements of Income for the three months ended March 31, 2023 was preliminary as Measurement Period Adjustments were recorded after March 31, 2023. The gain on acquisition of $9.81 billion, net of income taxes of $3.36 billion, was recorded in noninterest income during the year ended December 31, 2023, and represents the excess of the fair value of net assets acquired over the purchase price. The following is a description of the methods used to determine the estimated fair values of the Purchase Money Note and significant assets acquired and liabilities assumed, as presented above. Purchase Money Note The fair value of the Purchase Money Note was estimated based on the income approach, which includes: (i) projecting cash flows over a certain discrete projection period and (ii) discounting those projected cash flows to present value at a rate of return that considers the relative risk of the cash flows and the time value of money. Cash and interest-earning deposits at banks For financial instruments with a short-term or no stated maturity, prevailing market rates and limited credit risk, carrying amounts approximate fair value. Investment securities Fair values for securities are based on quoted market prices, where available. If quoted market prices are not available, fair value estimates are based on observable inputs including quoted market prices for similar instruments, quoted market prices that are not in an active market or other inputs that are observable in the market. In the absence of observable inputs, fair value is estimated based on pricing models and/or discounted cash flow methodologies. Loans Fair values for loans were based on a discounted cash flow methodology that considered factors including the type of loan and related collateral, classification status, fixed or variable interest rate, remaining term of loan, credit quality ratings or scores, amortization status and current discount rate. Loans with similar risk characteristics were pooled together and treated in aggregate when applying various valuation techniques. The discount rates used for loans were based on an evaluation of current market rates for new originations of comparable loans and required rates of return for market participants to purchase similar assets, including adjustments for liquidity and credit quality when necessary. BancShares’ accounting methods for acquired Non-PCD and PCD loans and leases are discussed in Note 1—Significant Accounting Policies and Basis of Presentation of the Notes to the Consolidated Financial Statements in our 2023 Form 10-K. The following table presents the unpaid principal balance (“UPB”) and fair value of the loans and leases acquired by BancShares in the SVBB Acquisition as of the SVBB Acquisition Date. The fair value of Non-PCD loans and leases was $66.42 billion, compared to the UPB of $68.72 billion, resulting in a discount of $2.30 billion that will be accreted into income over the contractual life of the applicable loan using the effective interest method. Loans and Leases Acquired dollars in millions Loans and Leases UPB Fair Value Non-PCD loans and leases $ 68,719 $ 66,422 PCD loans and leases 2,568 2,046 Total loans and leases, before PCD gross-up $ 71,287 $ 68,468 The following table summarizes PCD loans and leases that BancShares acquired in the SVBB Acquisition. PCD Loans and Leases dollars in millions Total PCD Loans from SVBB Acquisition UPB $ 2,568 Fair value 2,046 Total fair value discount 522 Less: discount for loans with $0 fair value at SVBB Acquisition Date 26 Less: PCD gross-up 220 Non-credit discount (1) $ 276 (1) The non-credit discount of $276 million will be accreted into income over the contractual life of the applicable loan using the effective interest method. Affordable housing tax credit investments The fair values of the affordable housing tax credit investments were determined based on discounted cash flows. The cash flow projections considered tax credits and net cash flows from operating losses and tax depreciation. The discount rate was determined using observable market data points for similar investments. Premises and equipment Fair values for furniture and fixtures, computer software and other equipment were determined using the cost approach. Core deposit intangible The following table presents the core deposit intangible recorded related to the valuation of core deposits: Core Deposit Intangible dollars in millions Fair Value Estimated Useful Life Amortization Method Core deposit intangible $ 230 8 years Effective yield Certain core deposits were acquired as part of the SVBB Acquisition, which provide an additional source of funds for BancShares. The core deposit intangible represents the costs saved by BancShares by acquiring the core deposits rather than sourcing the funds elsewhere. This intangible was valued using the after tax cost savings method under the income approach. This method estimates the fair value by discounting to present value the favorable funding spread attributable to the core deposit balances over their estimated average remaining life. The valuation considered a dynamic approach to interest rates and alternative cost of funds. The favorable funding spread is calculated as the difference in the alternative cost of funds and the net deposit cost. Refer to further discussion in Note 7—Goodwill and Core Deposit Intangibles. Other assets The following table details other assets acquired: Other Assets dollars in millions Fair Value Accrued interest receivable $ 431 Federal Home Loan Bank stock and Federal Reserve Bank stock 320 Fair value of derivative financial instruments 458 Other 355 Total other assets $ 1,564 The fair values of the derivative assets in the table above and derivative liabilities in the table below were valued using prices of financial instruments with similar characteristics and observable inputs. The fair value of accrued interest receivable and the remaining other assets was determined to approximate book value. Refer to further discussion in Note 12—Derivative Financial Instruments and Note 14—Fair Value. Deposits Acquired deposits were essentially all transactional deposits. Thus, we determined carrying amounts approximate fair value. Deferred tax liability The SVBB Acquisition is an asset acquisition for tax purposes and is therefore considered a taxable transaction. The deferred tax liability for the SVBB Acquisition was calculated by applying FCB’s deferred tax rate to the book and tax basis differences on the SVBB Acquisition Date for acquired assets and assumed liabilities. Deferred taxes were not recorded for the affordable housing tax credit investments in accordance with the proportional amortization method. The tax treatment of FDIC-assisted acquisitions is complex and subject to interpretations that may result in future adjustments of deferred taxes as of the SVBB Acquisition Date. Other liabilities The following table details other liabilities assumed: dollars in millions Fair Value Commitments to fund tax credit investments $ 715 Fair value of derivative financial instruments 497 Reserve for off-balance sheet credit exposures 253 Accrued interest payable 109 Other 461 Total other liabilities $ 2,035 The fair value of the liability representing our commitment for future capital contributions to the affordable housing tax credit investments was determined based on discounted cash flows. Projected cash flows for future capital contributions were discounted at a rate that represented FCB’s cost of debt. Shared-loss agreement intangibles Preliminary estimates indicate there is no material value to attribute to the loss indemnification asset or true-up liability. This is primarily based on evaluation of historical loss experience and the credit quality of the portfolio. Pro Forma Information - SVBB Acquisition SVBB was only in operation from March 10 to March 27, 2023 and does not have historical financial information on which we could base pro forma information. Additionally, we did not acquire all assets or assume all liabilities of SVBB and an essential part of the SVBB Acquisition is the federal assistance governed by the SVBB Purchase Agreement and Shared-Loss Agreement, which is not reflected in the previous operations of SVBB. Therefore, it is impracticable to provide unaudited pro forma information on revenues and earnings for the SVBB Acquisition in accordance with ASC 805-10-50-2. Net interest income, noninterest income and net income of $65 million, $14 million and $35 million, respectively, attributable to the SVBB Acquisition were included in BancShares’ Consolidated Statement of Income for the three months ended March 31, 2023.

Investments in government agency securities represent securities issued by the Small Business Association (“SBA”), Federal Home Loan Bank (“FHLB”) and other U.S. agencies. Investments in residential and commercial mortgage-backed securities represent securities issued by the Government National Mortgage Association, Federal National Mortgage Association and Federal Home Loan Mortgage Corporation. Investments in corporate bonds represent positions in debt securities of other financial institutions. Municipal bonds are general obligation bonds. Investments in marketable equity securities represent positions in common stock of publicly traded financial institutions. Investments in supranational securities represent securities issued by the Supranational Entities & Multilateral Development Banks. Other held to maturity investments include certificates of deposit with other financial institutions. BancShares held approximately 354,000 shares of Visa, Inc. (“Visa”) Class B common stock (“Visa Class B common stock”). Effective January 24, 2024, all outstanding shares of Visa Class B common stock were redenominated as Visa Class B-1 common stock (“Visa Class B-1 common stock”) pursuant to Visa’s eighth amended and restated certificate of incorporation. Until the resolution of certain litigation, at which time the Visa Class B-1 common stock will convert to publicly traded Visa Class A common stock, or the potential exchange of Visa Class B-1 common stock for other marketable classes of Visa common stock, these shares are only transferable to other stockholders of Visa Class B-1 common stock or certain new denominations of Visa’s former Class B common stock. As a result, there is limited transfer activity in private transactions between buyers and sellers. Given this limited trading activity and the continuing uncertainty regarding the likelihood, ultimate timing and eventual exchange of Visa Class B-1 common stock for shares of Visa Class A common stock or other marketable classes of Visa common stock, these shares are not considered to have a readily determinable fair value and have no carrying value. BancShares continues to monitor the trading activity in Visa Class B-1 common stock, the status of the resolution of certain litigation matters at Visa, and other potential exchange alternatives that would trigger the conversion of the Visa Class B-1 common stock into Visa Class A common stock or other marketable classes of Visa common stock. Accrued interest receivable for available for sale and held to maturity debt securities was excluded from the estimate for credit losses. At March 31, 2024, accrued interest receivable for available for sale and held to maturity debt securities was $121 million and $17 million, respectively. At December 31, 2023, accrued interest receivable for available for sale and held to maturity debt securities was $87 million and $18 million, respectively. During the three months ended March 31, 2024 and 2023, there was no accrued interest that was deemed uncollectible and written off against interest income. A security is considered past due once it is 30 days contractually past due under the terms of the agreement. There were no securities past due as of March 31, 2024 or December 31, 2023. The following table provides the amortized cost and fair value by contractual maturity. Expected maturities will differ from contractual maturities on certain securities because borrowers and issuers may have the right to call or prepay obligations with or without prepayment penalties. Residential and commercial mortgage-backed and government agency securities are stated separately as they are not due at a single maturity date.

BancShares has the ability and intent to retain these securities for a period of time sufficient to recover all unrealized losses. Given the consistently strong credit rating of the U.S. Treasury, and the long history of no credit losses on debt securities issued by government agencies and government sponsored entities, as of March 31, 2024, no allowance for credit loss was required. For corporate bonds, we analyzed the changes in interest rates relative to when the investment securities were purchased or acquired, and considered other factors including changes in credit ratings, delinquencies, and other macroeconomic factors. As a result of this analysis, we determined that no allowance for credit loss was required for investment securities available for sale as of March 31, 2024. BancShares’ portfolio of held to maturity debt securities consists of mortgage-backed securities issued by government agencies and government sponsored entities, U.S. Treasury notes, unsecured bonds issued by government agencies and government sponsored entities, and securities issued by the Supranational Entities & Multilateral Development Banks. Given the consistently strong credit rating of the U.S. Treasury, the Supranational Entities & Multilateral Development Banks and the long history of no credit losses on debt securities issued by government agencies and government sponsored entities, no allowance for credit loss was required for debt securities held to maturity as of March 31, 2024. There were no debt securities held to maturity on nonaccrual status as of March 31, 2024 or December 31, 2023. Investment securities having an aggregate carrying value of $3.90 billion at March 31, 2024, and $3.77 billion at December 31, 2023, were pledged as collateral to secure public funds on deposit and certain short-term borrowings, and for other purposes as required by law.

At March 31, 2024 and December 31, 2023, accrued interest receivable on loans included in other assets was $633 million and $625 million, respectively, and was excluded from the estimate of credit losses. The discount on acquired loans is accreted to interest income over the contractual life of the loan using the effective interest method. Discount accretion income, which primarily related to the SVBB Acquisition, was $163 million, including $35 million for unfunded commitments, for the three months ended March 31, 2024. The following table presents selected components of the amortized cost of loans, including the unamortized discount on acquired loans.

(2) Nonaccrual loans for which there was no related ALLL totaled $195 million at March 31, 2024 and $138 million at December 31, 2023. Other real estate owned (“OREO”) and repossessed assets were $58 million as of March 31, 2024 and $62 million as of December 31, 2023. Credit Quality Indicators Loans and leases are monitored for credit quality on a recurring basis. Commercial loans and leases and consumer loans have different credit quality indicators as a result of the unique characteristics of the loan classes being evaluated. The credit quality indicators for commercial loans and leases are developed through a review of individual borrowers on an ongoing basis. Commercial loans are evaluated periodically with more frequent evaluations done on criticized loans. The indicators as of the date presented are based on the most recent assessment performed and are defined below: Pass – A pass rated asset is not adversely classified because it does not display any of the characteristics for adverse classification. Special mention – A special mention asset has potential weaknesses which deserve management’s close attention. If left uncorrected, such potential weaknesses may result in deterioration of the repayment prospects or collateral position at some future date. Special mention assets are not adversely classified and do not warrant adverse classification. Substandard – A substandard asset is inadequately protected by the current net worth and paying capacity of the borrower or of the collateral pledged, if any. Assets classified as substandard generally have a well-defined weakness, or weaknesses, that jeopardize the liquidation of the debt. These assets are characterized by the distinct possibility of loss if the deficiencies are not corrected. Doubtful – An asset classified as doubtful has all the weaknesses inherent in an asset classified substandard with the added characteristic that the weaknesses make collection or liquidation in full highly questionable and improbable on the basis of currently existing facts, conditions and values. Loss – Assets classified as loss are considered uncollectible and of such little value it is inappropriate to be carried as an asset. This classification is not necessarily equivalent to any potential for recovery or salvage value, but rather it is not appropriate to defer a full charge-off even though partial recovery may be affected in the future. Ungraded – Ungraded loans represent loans not included in the individual credit grading process due to their relatively small balances or borrower type. The majority of ungraded loans at March 31, 2024 and December 31, 2023, relate to business credit cards. Business credit card loans are subject to automatic charge-off when they become 120 days past due in the same manner as unsecured consumer lines of credit. The credit quality indicator for consumer loans is based on delinquency status of the borrower as of the date presented. As the borrower becomes more delinquent, the likelihood of loss increases. An exemption is applied to government guaranteed loans as the principal repayments are insured by the Federal Housing Administration and U.S. Department of Veterans Affairs and thus remain on accrual status regardless of delinquency status. The following tables summarize the commercial and SVB loans disaggregated by year of origination and by risk rating. The consumer loan delinquency status by year of origination is also presented below. The tables reflect the amortized cost of the loans and include PCD loans.

BancShares’ modifications granted to debtors experiencing financial difficulties typically take the form of term extensions, interest rate reductions, payment delays, principal forgiveness, or a combination thereof. Modifications are made in accordance with internal policies and guidelines to conform to regulatory guidance. The following tables present the amortized cost of loan modifications made to debtors experiencing financial difficulty, disaggregated by class and type of loan modification. The tables also provide financial effects by type of such loan modifications for the respective loan class.

An assessment of whether a borrower is experiencing financial difficulty is reassessed or performed on the date of a modification. Since the effect of most modifications made to borrowers experiencing financial difficulty is already included in the ALLL because of the measurement methodologies used to estimate the ALLL, a change to the ALLL is generally not recorded upon modification. Upon BancShares’ determination that a modified loan (or portion of a loan) has subsequently been deemed uncollectible, the loan (or a portion of the loan) is charged off. At March 31, 2024, there were $84 million of loans modified in the twelve months ended March 31, 2024 which defaulted subsequent to modification.

ALLOWANCE FOR LOAN AND LEASE LOSSES	NOTE 5 — ALLOWANCE FOR LOAN AND LEASE LOSSES The ALLL is reported as a separate line item on the Consolidated Balance Sheets, while the reserve for off-balance sheet credit exposure is included in other liabilities, presented in Note 13—Other Liabilities. The provision or benefit for credit losses related to (i) loans and leases (ii) off-balance sheet credit exposure, and (iii) investment securities available for sale is reported in the Consolidated Statements of Income as provision or benefit for credit losses. The initial ALLL for PCD loans and leases acquired in the SVBB Acquisition (the “Initial PCD ALLL”) was established through a PCD gross-up and there was no corresponding increase to the provision for credit losses. The initial ALLL for Non-PCD loans and leases acquired in the SVBB Acquisition was established through a corresponding increase to the provision for credit losses (the “day 2 provision for loan and lease losses”). The initial reserve for off-balance sheet credit exposure acquired in the SVBB Acquisition was established through a corresponding increase to the provision for off-balance sheet credit exposure (the “day 2 provision for off-balance sheet credit exposure”). The accounting policy for loans and off-balance sheet credit exposure acquired in a business combination is further discussed in Note 1—Significant Accounting Policies and Basis of Presentation in the Notes to the Consolidated Financial Statements included in our 2023 Form 10-K. The ALLL activity for loans and leases is summarized in the following table.

Leases [Abstract]
LEASES	NOTE 6 — LEASES Lessee BancShares leases primarily include administrative offices and bank locations. Substantially all of our lease liabilities relate to United States real estate leases under operating lease arrangements. Our real estate leases have remaining lease terms of up to 33 years. Our lease terms may include options to extend or terminate the lease, and our operating leases have renewal terms that can extend from 1 to 25 years. The options are included in the lease term when it is determined that it is reasonably certain the option will be exercised. The following table presents supplemental balance sheet information and remaining weighted average lease terms and discount rates: Supplemental Lease Information dollars in millions Classification March 31, 2024 December 31, 2023 Lease assets: Operating lease ROU assets Other assets $ 355 $ 354 Finance leases Premises and equipment 8 9 Total lease assets $ 363 $ 363 Lease liabilities: Operating leases Other liabilities $ 397 $ 396 Finance leases Other borrowings 8 9 Total lease liabilities $ 405 $ 405 Weighted-average remaining lease terms: Operating leases 7.9 years 8.1 years Finance leases 15.7 years 15.4 years Weighted-average discount rate: Operating leases 2.76 % 2.70 % Finance leases 3.55 3.52 As of March 31, 2024, there were no leases that have not yet commenced that would have a material impact on BancShares’ consolidated financial statements.

Operating lease cost is recognized as a single lease cost on a straight-line basis over the lease term. For finance leases, the right of use (“ROU”) asset is amortized straight-line over the lease term as equipment expense and interest on the lease liability is recognized separately; however, interest on the lease liability was less than $1 million per year and is therefore not presented in the table above. Variable lease cost includes common area maintenance, property taxes, utilities, and other operating expenses related to leased premises recognized in the period in which the expense was incurred. Certain of our lease agreements also include rental payments adjusted periodically for inflation. While lease liabilities are not remeasured because of these changes, these adjustments are treated as variable lease costs and recognized in the period in which the expense is incurred. Sublease income results from leasing excess building space that BancShares is no longer utilizing under operating leases, which have remaining lease terms of up to 13 years.

VARIABLE INTEREST ENTITIES	NOTE 8 — VARIABLE INTEREST ENTITIES Refer to Note 1—Significant Accounting Policies and Basis of Presentation for additional information on accounting for VIEs. Consolidated VIEs At March 31, 2024 and December 31, 2023, there were no consolidated VIEs. Unconsolidated VIEs Unconsolidated VIEs include limited partnership interests and joint ventures where BancShares’ involvement is limited to an investor interest and BancShares does not have the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance or obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. The table below provides a summary of the assets and liabilities included on the Consolidated Balance Sheets associated with unconsolidated VIEs. The table also presents our maximum exposure to loss which consists of outstanding book basis and unfunded commitments for future investments, and represents potential losses that would be incurred under hypothetical circumstances, such that the value of BancShares’ interests and any associated collateral declines to zero and assuming no recovery. BancShares believes the possibility is remote under this hypothetical scenario; accordingly, this disclosure is not an indication of expected loss.

(2) Represents commitments to invest in qualified affordable housing investments and other investments qualifying for community reinvestment tax credits. These commitments are payable on demand and are included in other liabilities. BancShares has investments in qualified affordable housing projects primarily for the purposes of fulfilling Community Reinvestment Act of 1977 (“CRA”) requirements and obtaining tax credits. These investments are accounted for using PAM and provide tax benefits to investors in the form of tax deductions from operating losses and tax credits. Under PAM, the initial cost of the investment is amortized in proportion to the tax credits and other tax benefits received, and the net investment performance is recognized in the income statement as a component of income tax expense. The table below summarizes the amortization of our affordable housing tax credit investments and the related tax credits and other tax benefits that are recognized in income tax expense.

Debt Disclosure [Abstract]
BORROWINGS	NOTE 11 — BORROWINGS Short-term Borrowings Securities Sold under Agreements to Repurchase BancShares held $395 million and $485 million at March 31, 2024 and December 31, 2023, respectively, of securities sold under agreements to repurchase that have overnight contractual maturities and are collateralized by government agency securities. BancShares utilizes securities sold under agreements to repurchase to facilitate the needs for collateralization of commercial customers and secure wholesale funding needs. Repurchase agreements are transactions whereby BancShares offers to sell to a counterparty an undivided interest in an eligible security at an agreed upon purchase price, and which obligates BancShares to repurchase the security at an agreed upon date, repurchase price and interest rate. These agreements are recorded at the amount of cash received in connection with the transactions and are reflected as securities sold under customer repurchase agreements. BancShares monitors collateral levels on a continuous basis and maintains records of each transaction specifically describing the applicable security and the counterparty’s fractional interest in that security, and segregates the security from general assets in accordance with regulations governing custodial holdings of securities. The primary risk with repurchase agreements is market risk associated with the investments securing the transactions, as additional collateral may be required based on fair value changes of the underlying investments. Securities pledged as collateral under repurchase agreements are maintained with safekeeping agents. The carrying value of investment securities pledged as collateral under repurchase agreements was $487 million and $502 million at March 31, 2024 and December 31, 2023, respectively. Long-term Borrowings Long-term borrowings at March 31, 2024 and December 31, 2023 include: Long-term Borrowings dollars in millions Maturity March 31, 2024 December 31, 2023 Parent Company: Subordinated: Fixed-to-Floating subordinated notes at 3.375% March 2030 $ 350 $ 350 Junior subordinated debentures (FCB/SC Capital Trust II) (1) June 2034 — 20 Subsidiaries: Senior: Senior unsecured fixed-to-floating rate notes at 2.969% September 2025 315 316 Fixed senior unsecured notes at 6.00% April 2036 51 51 Subordinated: Fixed subordinated notes at 6.125% March 2028 400 404 Fixed-to-Fixed subordinated notes at 4.125% November 2029 100 100 Junior subordinated debentures (SCB Capital Trust I) (1) April 2034 — 10 Secured: Purchase Money Note to FDIC fixed at 3.50% (2) March 2028 36,072 36,072 Capital lease obligations Maturities through May 2057 8 9 Unamortized purchase accounting adjustments (151) (163) Total long-term borrowings $ 37,145 $ 37,169 (1) The borrowings were called during the first quarter of 2024, resulting in a $2 million loss on extinguishment of debt for the three months ended March 31, 2024.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	NOTE 12 — DERIVATIVE FINANCIAL INSTRUMENTS Our derivatives that are designated as hedging instruments include interest rate swaps that we utilize to manage our interest rate exposure on certain fixed-rate borrowings and deposits included on our Consolidated Balances Sheets. Our derivatives not designated as hedging instruments mainly include interest rate and foreign exchange contracts that our customers utilize to manage their risk management needs. We typically manage our exposure to these customer derivatives by entering into offsetting or “back-to-back” interest rate and foreign exchange contracts with third-party dealers. Derivative instruments that are cleared through certain central counterparty clearing houses are settled-to-market and reported net of collateral positions. The following table presents notional amounts and fair values of derivative financial instruments: Notional Amount and Fair Value of Derivative Financial Instruments dollars in millions March 31, 2024 December 31, 2023 Notional Amount Asset Fair Value Liability Fair Value Notional Amount Asset Fair Value Liability Fair Value Derivatives designated as hedging instruments (Qualifying hedges) Interest rate contracts – fair value hedges (1) (4) $ 1,149 $ — $ — $ 815 $ — $ — Derivatives not designated as hedging instruments (Non-qualifying hedges) Interest rate contracts (1) (4) $ 25,623 $ 573 $ (590) $ 24,548 $ 530 $ (518) Foreign exchange contracts (2) 8,630 78 (63) 9,142 104 (117) Other contracts (3) 1,145 8 (1) 983 6 (1) Total derivatives not designated as hedging instruments $ 35,398 $ 659 $ (654) $ 34,673 $ 640 $ (636) Gross derivatives fair values presented in the Consolidated Balance Sheets $ 659 $ (654) $ 640 $ (636) Less: gross amounts offset in the Consolidated Balance Sheets — — — — Net amount presented in other assets and other liabilities in the Consolidated Balance Sheets 659 (654) 640 (636) Less: amounts subject to master netting agreements (5) (61) 61 (97) 97 Less: cash collateral pledged (received) subject to master netting agreements (6) (534) 8 (405) 39 Total net derivative fair value $ 64 $ (585) $ 138 $ (500) (1) Fair value balances include accrued interest. (2) The foreign exchange contracts exclude foreign exchange spot contracts. The notional and net fair value amounts of these contracts were $324 million and $1 million, respectively, as of March 31, 2024, and $179 million and $0 million, respectively, as of December 31, 2023. (3) Other derivative contracts not designated as hedging instruments include risk participation agreements and equity warrants. (4) BancShares accounts for swap contracts cleared by the Chicago Mercantile Exchange and LCH Clearnet as “settled-to-market.” As a result, variation margin payments are characterized as settlement of the derivative exposure and variation margin balances are netted against the corresponding derivative mark-to-market balances. Gross amounts of recognized assets and liabilities were lowered by $83 million and $26 million, respectively, at March 31, 2024, which includes $0 million and $0 million relating to qualifying hedges, respectively. Gross amounts of recognized assets and liabilities were lowered by $66 million and $37 million, respectively, at December 31, 2023, which includes $4 million and $0 million relating to qualifying hedges, respectively. (5) BancShares’ derivative transactions are governed by International Swaps and Derivatives Association (“ISDA”) agreements that allow for net settlements of certain payments as well as offsetting of all contracts with a given counterparty in the event of bankruptcy or default of one of the two parties to the transaction. BancShares believes its ISDA agreements meet the definition of a master netting arrangement or similar agreement for purposes of the above disclosure. (6) In conjunction with the ISDA agreements described above, BancShares has entered into collateral arrangements with its counterparties, which provide for the exchange of cash depending on the change in the market valuation of the derivative contracts outstanding.

Fair Value Disclosures [Abstract]
FAIR VALUE	NOTE 14 — FAIR VALUE Fair Value Hierarchy BancShares measures certain financial assets and liabilities at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. GAAP also establishes a fair value hierarchy, which prioritizes the inputs to valuation techniques used to measure fair value into three levels. Assets and liabilities are recorded at fair value according to a fair value hierarchy comprised of three levels. The levels are based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. The level within the fair value hierarchy for an asset or liability is based on the lowest level of input significant to the fair value measurement with Level 1 inputs considered highest and Level 3 inputs considered lowest. A brief description of each input level follows: • Level 1 inputs are quoted prices in active markets for identical assets and liabilities. • Level 2 inputs are quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and inputs other than quoted prices observable for the assets or liabilities and market corroborated inputs. • Level 3 inputs are unobservable inputs for the asset or liability. These unobservable inputs and assumptions reflect the estimates market participants would use in pricing the asset or liability.

The methods and assumptions used to estimate the fair value of each class of financial instruments measured at fair value on a recurring basis are as follows: Investment securities available for sale . The fair value of U.S. Treasury, government agency, mortgage-backed securities, municipal bonds, and a portion of the corporate bonds are generally estimated using a third-party pricing service. To obtain an understanding of the processes and methodologies used, management reviews correspondence from the third-party pricing service. Management also performs a price variance analysis process to corroborate the reasonableness of prices. The third-party provider evaluates securities based on comparable investments with trades and market data and will utilize pricing models which use a variety of inputs, such as benchmark yields, reported trades, issuer spreads, benchmark securities, bids and offers as needed. These securities are generally classified as Level 2. The remaining corporate bonds held are generally measured at fair value based on indicative bids from broker-dealers using inputs that are not directly observable. These securities are classified as Level 3. Marketable equity securities. Equity securities are measured at fair value using observable closing prices. The valuation also considers the amount of market activity by examining the trade volume of each security. Equity securities are classified as Level 1 if they are traded in an active market and as Level 2 if the observable closing price is from a less than active market. Loans held for sale. Certain residential real estate loans originated for sale to investors are carried at fair value based on quoted market prices for similar types of loans. Accordingly, the inputs used to calculate fair value of originated residential real estate loans held for sale are considered Level 2 inputs. Derivative Assets and Liabilities. Derivatives were valued using models that incorporate inputs depending on the type of derivative. Other than the fair value of equity warrants and credit derivatives, which were estimated using Level 3 inputs, most derivative instruments were valued using Level 2 inputs based on observed pricing for similar assets and liabilities and model-based valuation techniques for which all significant assumptions are observable in the market. See Note 12—Derivative Financial Instruments for notional amounts and fair values. The following tables summarize information about significant unobservable inputs related to BancShares’ categories of Level 3 financial assets and liabilities measured on a recurring basis: Quantitative Information About Level 3 Fair Value Measurements - Recurring Basis dollars in millions Financial Instrument Estimated Valuation Significant Unobservable Inputs March 31, 2024 Assets Corporate bonds $ 161 Indicative bid provided by broker Multiple factors, including but not limited to, current operations, financial condition, cash flows, and recently executed financing transactions related to the issuer.

This election reduces certain timing differences in the Consolidated Statements of Income and better aligns with the management of the portfolio from a business perspective. The changes in fair value that were recorded as a component of mortgage income were insignificant for the three months ended March 31, 2024 and 2023. Interest earned on loans held for sale is recorded within interest income on loans and leases in the Consolidated Statements of Income. No originated loans held for sale were 90 or more days past due or on nonaccrual status as of March 31, 2024 or December 31, 2023. Assets Measured at Estimated Fair Value on a Non-recurring Basis Certain assets or liabilities are required to be measured at estimated fair value on a non-recurring basis subsequent to initial recognition. Generally, these adjustments are the result of lower of the cost or market value (“LOCOM”) or other impairment accounting. The following table presents carrying value of assets measured at estimated fair value on a non-recurring basis for which gains and losses have been recorded in the periods. The gains and losses reflect amounts recorded for the respective periods, regardless of whether the asset is still held at period end. Assets Measured at Fair Value - Non-recurring Basis dollars in millions Fair Value Measurements Total Level 1 Level 2 Level 3 Total Gains (Losses) March 31, 2024 Assets held for sale - loans $ 11 $ — $ — $ 11 $ (4) Loans - collateral dependent loans 157 — — 157 (30) Other real estate owned 36 — — 36 3 Total $ 204 $ — $ — $ 204 $ (31) December 31, 2023 Assets held for sale - loans $ 12 $ — $ — $ 12 $ (4) Loans - collateral dependent loans 265 — — 265 (131) Other real estate owned 16 — — 16 4 Total $ 293 $ — $ — $ 293 $ (131) Certain other assets are adjusted to their fair value on a non-recurring basis, including certain loans, OREO, and goodwill, which are periodically tested for impairment. Most loans held for investment, deposits, and borrowings are not reported at fair value. The methods and assumptions used to estimate the fair value of each class of financial instruments measured at fair value on a non-recurring basis are as follows: Assets held for sale - loans. Loans held for investment subsequently transferred to held for sale are carried at the LOCOM. When available, the fair values for the transferred loans are based on quoted prices from the purchase commitments for the individual loans being transferred and are considered Level 1 inputs. The fair value of Level 2 assets was primarily estimated based on prices of recent trades of similar assets. For other loans held for sale, the fair value of Level 3 assets was primarily measured under the income approach using the discounted cash flow model based on Level 3 inputs including discount rate or the price of committed trades. Loans - collateral dependent loans. The population of Level 3 loans measured at fair value on a non-recurring basis includes collateral-dependent loans evaluated individually. Collateral values are determined using appraisals or other third-party value estimates of the subject property discounted based on estimated selling costs, and adjustments for other external factors that may impact the marketability of the collateral. Other real estate owned. OREO is carried at LOCOM. OREO asset valuations are determined by using appraisals or other third-party value estimates of the subject property with discounts, generally between 6% and 10%, applied for estimated selling costs and other external factors that may impact the marketability of the property. At March 31, 2024 and December 31, 2023, the weighted average discount applied was 8.24% and 8.59%, respectively. Changes to the value of the assets between scheduled valuation dates are monitored through continued communication with brokers and monthly reviews by the asset manager assigned to each asset. If there are any significant changes in the market or the subject property, valuations are adjusted or new appraisals are ordered to ensure the reported values reflect the most current information.

The carrying value of interest-earning deposits at banks approximates its fair value due to its short-term nature. The balances at March 31, 2024 and December 31, 2023 included $213 million and $211 million, respectively, as a required minimum deposit under the Advance Facility Agreement. Net loans. The carrying value of net loans is net of the ALLL. Loans are generally valued by discounting expected cash flows using market inputs with adjustments based on cohort level assumptions for certain loan types as well as internally developed estimates at a business segment level. Due to the significance of the unobservable market inputs and assumptions, as well as the absence of a liquid secondary market for most loans, these loans are classified as Level 3. Certain loans are measured based on observable market prices sourced from external data providers and classified as Level 2. Nonaccrual loans are written down and reported at their estimated recovery value which approximates their fair value and classified as Level 3. Securities Purchased Under Agreement to Resell. The fair value of securities purchased under agreement to resell equal the carrying value due to the short term nature, generally overnight, and therefore present an insignificant risk of change in fair value due to changes in market interest rate, and classified as Level 2. Investment securities held to maturity. BancShares’ portfolio of debt securities held to maturity consists of mortgage-backed securities issued by government agencies and government sponsored entities, U.S. Treasury notes, unsecured bonds issued by government agencies and government sponsored entities, and securities issued by the Supranational Entities & Multilateral Development Banks. We primarily use prices obtained from pricing services to determine the fair value of securities, which are Level 2 inputs. FHLB stock. The carrying amount of FHLB stock is a reasonable estimate of fair value, as these securities are not readily marketable and are evaluated for impairment based on the ultimate recoverability of the par value. BancShares considers positive and negative evidence, including the profitability and asset quality of the issuer, dividend payment history and recent redemption experience, when determining the ultimate recoverability of the par value. BancShares investment in FHLB stock is ultimately recoverable at par. The inputs used in the fair value measurement for the FHLB stock are considered Level 2 inputs. Mortgage servicing rights (“MSRs”). MSRs are initially recorded at fair value and subsequently carried at the lower of amortized cost or market. Therefore, servicing rights are carried at fair value only when fair value is less than the amortized cost. The fair value of MSRs is determined using a pooling methodology. Similar loans are pooled together and a model which relies on discount rates, estimates of prepayment rates and the weighted average cost to service the loans is used to determine the fair value. The inputs used in the fair value measurement for MSRs are considered Level 3 inputs. Deposits. The estimated fair value of deposits with no stated maturity, such as demand deposit accounts, money market accounts, and savings accounts was the amount payable on demand at the reporting date. The fair value of time deposits was estimated based on a discounted cash flow technique using Level 2 inputs appropriate to the contractual maturity. Credit balances of factoring clients. The impact of the time value of money from the unobservable discount rate for credit balances of factoring clients is inconsequential due to the short term nature of these balances, therefore, the fair value approximated carrying value, and the credit balances were classified as Level 3. Short-term borrowed funds. Includes repurchase agreements and certain other short-term borrowings. The fair value approximates carrying value and are classified as Level 2. Long-term borrowings. For certain long-term senior and subordinated unsecured borrowings, the fair values are sourced from a third-party pricing service. The fair values of other long-term borrowings are determined by discounting future cash flows using current interest rates for similar financial instruments. The inputs used in the fair value measurement for FHLB borrowings, senior and subordinated debentures, and other borrowings are classified as Level 2. For all other financial assets and financial liabilities, the carrying value is a reasonable estimate of the fair value as of March 31, 2024 and December 31, 2023. The carrying value and fair value for these assets and liabilities are equivalent because they are relatively short-term in nature and there is no interest rate or credit risk that would cause the fair value to differ from the carrying value. Cash and due from banks, and interest-earning deposits at banks, are classified on the fair value hierarchy as Level 1. Accrued interest receivable and accrued interest payable are classified as Level 2.

Income Tax Disclosure [Abstract]
INCOME TAXES	NOTE 18 — INCOME TAXES BancShares’ global effective income tax rates (“ETRs”) were 27.2% and (0.5)% for the three months ended March 31, 2024 and 2023, respectively. The increase in the effective tax rate from (0.5)% in the prior year to 27.2% for the three months ended March 31, 2024 was primarily due to the effects of the non-taxable nature of the gain on acquisition relating to the SVBB Acquisition in the prior year quarter. The quarterly income tax expense is based on a projection of BancShares’ annual ETR. This annual ETR is applied to the year-to-date consolidated pretax income to determine the interim provision for income taxes before discrete items. The ETR each period is also impacted by a number of factors, including the relative mix of domestic and international earnings, effects of changes in enacted tax laws, adjustments to the valuation allowances, and discrete items. The currently forecasted ETR may vary from the actual year-end 2024 ETR due to the changes in these factors. Uncertain Tax Benefits BancShares’ recognizes tax benefits when it is more likely than not that the position will prevail, based solely on the technical merits under the tax law of the relevant jurisdiction. BancShares will recognize the tax benefit if the position meets this recognition threshold determined based on the largest amount of the benefit that is more than likely to be realized.

Segment Reporting [Abstract]
BUSINESS SEGMENT INFORMATION	NOTE 20 — BUSINESS SEGMENT INFORMATION We made changes to our segment reporting during the first quarter of 2024 as further discussed in Note 1—Significant Accounting Policies and Basis of Presentation. Segment disclosures for 2023 periods included in this Form 10-Q were recast to reflect the segment reporting changes. BancShares’ segments at March 31, 2024 include General Bank, Commercial Bank, SVB Commercial, and Rail. All other financial information not allocated to the segments is included in the “Corporate” section of the segment disclosures. The segment descriptions below reflect the segment reporting changes made during the first quarter of 2024. General Bank The General Bank segment delivers products and services to consumers and businesses through our extensive network of branches and various digital channels. We offer a full suite of deposit products, loans (primarily residential mortgages and business and commercial loans), cash management, private banking and wealth management, payment services, and treasury services. We offer conforming and jumbo residential mortgage loans throughout the United States that are primarily originated through branches and retail referrals, employee referrals, internet leads, direct marketing and a correspondent lending channel, as well as through our private banking service. Private banking and wealth management offers a customized suite of products and services to individuals and institutional clients, as well as private equity and venture capital professionals and executive leaders of the innovation companies they support, and premium wine clients. The General Bank segment offers brokerage, investment advisory, private stock loans, other secured and unsecured lending products and vineyard development loans, as well as planning-based financial strategies, family office, financial planning, tax planning and trust services. The General Bank segment also includes a community association bank channel that supports deposit, cash management, and lending to homeowner associations and property management companies. Revenue is generated from interest earned on loans and from fees for banking and advisory services. We primarily originate loans by utilizing our branch network and industry referrals, as well as direct digital marketing efforts. We derive our SBA loans through a network of SBA originators. We periodically purchase loans on a whole-loan basis. We also invest in community development that supports the construction of affordable housing in our communities in line with our CRA initiatives. Commercial Bank The Commercial Bank segment provides a range of lending, leasing, capital markets, asset management and other financial and advisory services, primarily to small and middle market companies in a wide range of industries including: energy; healthcare; tech media and telecom; asset-backed lending; capital finance; maritime; corporate banking; aerospace and defense; and sponsor finance. Loans offered are primarily senior secured loans collateralized by accounts receivable, inventory, machinery and equipment, transportation equipment and/or intangibles, and are often used for working capital, plant expansion, acquisitions, or recapitalizations. These loans include revolving lines of credit and term loans and, depending on the nature of the collateral, may be referred to as collateral-backed loans, asset-based loans or cash flow loans. We provide senior secured loans to developers and other CRE professionals. Additionally, we provide small business loans and leases, including both capital and operating leases, through a highly automated credit approval, documentation and funding process. We provide factoring, receivable management, and secured financing to businesses that operate in several industries. These include: apparel, textile, furniture, home furnishings, and consumer electronics. Factoring entails the assumption of credit risk with respect to trade accounts receivable arising from the sale of goods from our factoring clients to their customers that have been factored (i.e., sold or assigned to the factor). Our factoring clients, which are generally manufacturers or importers of goods, are the counterparties on factoring, financing, or receivables purchasing agreements to sell trade receivables to us. Our factoring clients’ customers, which are generally retailers, are the account debtors and obligors on trade accounts receivable that have been factored. Revenue is generated from: interest and fees on loans; rental income on operating lease equipment; fee income and other revenue from banking services and capital markets transactions; and commissions earned on factoring-related activities. We derive most of our commercial lending business through direct marketing to borrowers, lessees, manufacturers, vendors, and distributors. We also utilize referrals as a source for commercial lending business. We may periodically buy participations or syndications of loans and lines of credit and purchase loans on a whole-loan basis. SVB Commercial The SVB Commercial segment offers products and services to commercial clients and investors across stages, sectors and regions in the innovation ecosystem, as well as private equity and venture capital firms. The SVB Commercial segment provides solutions to the financial needs of commercial clients. Loan products consists of capital call lines of credit, investor dependent loans, cash flow dependent loans, and innovation C&I loans made primarily to technology and life science/healthcare companies. Revenue is primarily generated from interest earned on loans, and fees and other revenue from lending activities and banking services. Deposit products include business and analysis checking accounts, money market accounts, multi-currency accounts, bank accounts, sweep accounts and positive pay services. Services are provided through online and mobile banking platforms, as well as branch locations. Rail The Rail segment offers customized leasing and financing solutions on a fleet of railcars and locomotives to railroads and shippers throughout North America. Railcar types include covered hopper cars used to ship grain and agricultural products, plastic pellets, sand, and cement; tank cars for energy products and chemicals; gondolas for coal, steel coil and mill service products; open-top hopper cars for coal and aggregates; boxcars for paper and auto parts; and centerbeams and flat cars for lumber. Revenue is generated primarily from rental income on operating lease equipment. Corporate Corporate includes all other financial information not allocated to the segments. Corporate contains BancShares’ centralized Treasury function which manages the investment security portfolio, interest-earning deposits at banks, and corporate/wholesale funding (e.g., borrowings, Direct Bank deposits, and brokered deposits). Corporate deposits are primarily comprised of Direct Bank deposits. Corporate includes interest income on investment securities and interest-earning deposits at banks; interest expense for borrowings, Direct Bank deposits, and brokered deposits; funds transfer pricing allocations; gains or losses on sales of investment securities; fair value adjustments on marketable equity securities; income from bank-owned life insurance; portions of salaries and benefits expense; and acquisition-related expenses. Corporate also includes certain items related to accounting for business combinations, such as gains on acquisitions, day 2 provisions for credit losses, and discount accretion income for certain acquired loans.

COMMITMENTS AND CONTINGENCIES

COMMITMENTS AND CONTINGENCIES	3 Months Ended

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	NOTE 21 — COMMITMENTS AND CONTINGENCIES Commitments To meet the financing needs of its customers, BancShares and its subsidiaries have financial instruments with off-balance sheet risk. These financial instruments involve elements of credit, interest rate or liquidity risk and include commitments to extend credit and standby letters of credit. The accompanying table summarizes credit-related commitments and other purchase and funding commitments: dollars in millions March 31, 2024 December 31, 2023 Financing Commitments Financing assets (excluding leases) $ 56,685 $ 57,567 Letters of Credit Standby letters of credit 2,224 2,412 Other letters of credit 104 103 Deferred Purchase Agreements 1,742 2,076 Purchase and Funding Commitments (1) 551 685 (1) BancShares’ purchase and funding commitments relate to the equipment leasing businesses’ commitments to fund Rail’s railcar manufacturer purchase and upgrade commitments. Financing Commitments Commitments to extend credit are legally binding agreements to lend to customers. These commitments generally have fixed expiration dates or other termination clauses and may require payment of fees. Established credit standards control the credit risk exposure associated with these commitments. In some cases, BancShares requires collateral be pledged to secure the commitment, including cash deposits, securities and other assets. Financing commitments, referred to as loan commitments or lines of credit, primarily reflect BancShares’ agreements to lend to its customers, subject to the customers’ compliance with contractual obligations. At March 31, 2024 and 2023, substantially all undrawn financing commitments were senior facilities. Financing commitments also include $79 million and $66 million at March 31, 2024 and December 31, 2023, respectively, related to off-balance sheet commitments to fund equity investments. Commitments to fund equity investments are contingent on events that have yet to occur and may be subject to change. As financing commitments may not be fully drawn, may expire unused, may be reduced or canceled at the customer’s request, and may require the customer to be in compliance with certain conditions, commitment amounts do not necessarily reflect actual future cash flow requirements. The table above excludes uncommitted revolving credit facilities extended by Commercial Services to its clients for working capital purposes. In connection with these facilities, Commercial Services has the sole discretion throughout the duration of these facilities to determine the amount of credit that may be made available to its clients at any time and whether to honor any specific advance requests made by its clients under these credit facilities. Letters of Credit Standby letters of credit are commitments to pay the beneficiary thereof if drawn upon by the beneficiary upon satisfaction of the terms of the letter of credit. Those commitments are primarily issued to support public and private borrowing arrangements. To mitigate its risk, BancShares’ credit policies govern the issuance of standby letters of credit. The credit risk related to the issuance of these letters of credit is essentially the same as in extending loans to clients and, therefore, these letters of credit are collateralized when necessary. These financial instruments generate fees and involve, to varying degrees, elements of credit risk in excess of amounts recognized in the Consolidated Balance Sheets. Deferred Purchase Agreements A deferred purchase agreement (“DPA”) is provided in conjunction with factoring, whereby a client is provided with credit protection for trade receivables without purchasing the receivables. The trade receivables terms generally require payment in 90 days or less. If the client’s customer is unable to pay an undisputed receivable solely as the result of credit risk, BancShares is then required to purchase the receivable from the client, less any borrowings for such client based on such defaulted receivable. The outstanding amount in the table above, less $119 million and $143 million at March 31, 2024 and December 31, 2023, respectively, of borrowings for such clients, is the maximum amount that BancShares would be required to pay under all DPAs. This maximum amount would only occur if all receivables subject to DPAs default in the manner described above, thereby requiring BancShares to purchase all such receivables from the DPA clients. The table above includes $1.59 billion and $1.92 billion of DPA exposures at March 31, 2024 and December 31, 2023, respectively, related to receivables on which BancShares has assumed the credit risk. The table also includes $151 million and $161 million available under DPA credit line agreements provided at March 31, 2024 and December 31, 2023, respectively. The DPA credit line agreements specify a contractually committed amount of DPA credit protection and are cancellable by us only after a notice period, which is typically 90 days or less. Litigation and Other Contingencies The Parent Company and certain of its subsidiaries have been named as a defendant in legal actions arising from its normal business activities in which damages in various amounts are claimed. BancShares is also exposed to litigation risk relating to the prior business activities of banks from which assets were acquired and liabilities assumed. BancShares is involved, and from time to time in the future may be involved, in a number of pending and threatened judicial, regulatory, and arbitration proceedings as well as proceedings, investigations, examinations and other actions brought or considered by governmental and self-regulatory agencies. These matters arise in connection with the ordinary conduct of BancShares’ business. At any given time, BancShares may also be in the process of responding to subpoenas, requests for documents, data and testimony relating to such matters and engaging in discussions to resolve the matters (all of the foregoing collectively being referred to as “Litigation”). While most Litigation relates to individual claims, BancShares may be subject to putative class action claims and similar broader claims and indemnification obligations. In light of the inherent difficulty of predicting the outcome of Litigation matters and indemnification obligations, particularly when such matters are in their early stages or where the claimants seek indeterminate damages, BancShares cannot state with confidence what the eventual outcome of the pending Litigation will be, what the timing of the ultimate resolution of these matters will be, or what the eventual loss, fines, or penalties related to each pending matter will be, if any. In accordance with applicable accounting guidance, BancShares’ establishes reserves for Litigation when those matters present loss contingencies as to which it is both probable that a loss will occur and the amount of such loss can reasonably be estimated. Based on currently available information, BancShares believes that the outcome of Litigation that is currently pending will not have a material adverse effect on BancShares’ financial condition, but may be material to BancShares’ operating results or cash flows for any particular period, depending in part on its operating results for that period. The actual results of resolving such matters may be substantially higher than the amounts reserved. For certain Litigation matters in which BancShares is involved, BancShares is able to estimate a range of reasonably possible losses in excess of established reserves and insurance. For other matters for which a loss is probable or reasonably possible, such an estimate cannot be determined. For Litigation and other matters where losses are reasonably possible, management currently estimates an aggregate range of reasonably possible losses of up to $10 million in excess of any established reserves and any insurance we reasonably believe we will collect related to those matters. This estimate represents reasonably possible losses (in excess of established reserves and insurance) over the life of such Litigation, which may span a currently indeterminable number of years, and is based on information currently available as of March 31, 2024. The Litigation matters underlying the estimated range will change from time to time, and actual results may vary significantly from this estimate. Those Litigation matters for which an estimate is not reasonably possible or as to which a loss does not appear to be reasonably possible, based on current information, are not included within this estimated range and, therefore, this estimated range does not represent BancShares’ maximum loss exposure. The foregoing statements about BancShares’ Litigation are based on BancShares’ judgments, assumptions, and estimates and are necessarily subjective and uncertain. In the event of unexpected future developments, it is possible that the ultimate resolution of these cases, matters, and proceedings, if unfavorable, may be material to BancShares’ consolidated financial position in a particular period.

Reclassifications	Reclassifications Financial Statements In certain instances, amounts reported in the 2023 consolidated financial statements have been reclassified to conform to the current financial statement presentation. Such reclassifications had no effect on previously reported stockholders’ equity or net income. Reportable Segments At December 31, 2023, BancShares reported its financial results in the General Bank, Commercial Bank, Silicon Valley Bank (“SVB”), and Rail segments. All other financial information was included in the “Corporate” section of the segment disclosures. We made the following changes to our segment reporting during the first quarter of 2024: • the private banking and wealth management components of the SVB segment were integrated into the General Bank segment which already included other wealth management activities; • the SVB segment was renamed SVB Commercial as its customers primarily include commercial clients in key innovation markets, as well as private equity and venture capital clients; and • the Direct Bank (a nationwide digital banking platform that delivers deposit products to consumers) previously allocated to the General Bank segment was transitioned to Corporate which already included borrowings and brokered deposits. Segment disclosures for 2023 periods included in this Form 10-Q were recast to reflect the segment reporting changes summarized above. Refer to Note 20—Business Segment Information for additional information. Loan Classes At December 31, 2023, our disclosures for loans and leases and the allowance for loan and lease losses (“ALLL”) were aggregated into Commercial, Consumer, and SVB portfolios, each of which consisted of several loan classes. The SVB portfolio consisted of the following loan classes: global fund banking, investor dependent - early stage, investor dependent - growth stage, innovation Commercial and Industrial (“innovation C&I”) and cash flow dependent, private bank, commercial real estate (“CRE”), and “other.” For further information, refer to Note 1—Significant Accounting Policies and Basis of Presentation in the Notes to the Consolidated Financial Statements included in our 2023 Form 10-K. During the first quarter of 2024, the private bank, CRE, and “other” loan classes described below, which were mapped to the SVB portfolio at December 31, 2023, were remapped to the applicable loan classes within the Commercial and Consumer portfolios. • The private bank loan class included loans to clients who are primarily private equity or venture capital professionals and executives in the innovation companies, as well as high net worth clients. This loan class included mortgages, home equity lines of credit, restricted and private stock loans, personal capital call lines of credit, lines of credit against liquid assets, and other secured and unsecured lending products. In addition, this class included owner occupied commercial mortgages and real estate secured loans. • The CRE loan class consisted generally of acquisition financing loans for commercial properties including office buildings, retail properties, apartment buildings and industrial/warehouse space. • The “other” loan class included smaller acquired portfolios, such as commercial and industrial, premium wine, and other acquired portfolios. Certain loans secured by other nonfarm, nonresidential properties, which were mapped to the owner occupied commercial mortgage loan class at December 31, 2023, were remapped to the non-owner occupied commercial mortgage loan class during the first quarter of 2024.
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions based on available information. These estimates and assumptions impact the amounts reported in the consolidated financial statements and accompanying notes and the disclosures provided, and actual results could differ from those estimates. The significant estimate related to the determination of the ALLL is considered a critical accounting estimate.
Newly Adopted Accounting Standards	Newly Adopted Accounting Standards As of January 1, 2024, BancShares adopted the following Accounting Standards Updates (“ASUs”) issued by the Financial Accounting Standards Board (“FASB”): ASU 2023-02 – Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method, Issued March 2023 The amendments in this ASU allow entities to elect to account for qualifying tax equity investments using the proportional amortization method (“PAM”), regardless of the program giving rise to the related income tax credits. PAM accounting had been available only for qualifying investments in qualified affordable housing projects. This ASU also requires disclosure of the nature of the investor’s tax equity investments and the effect of income tax credits and other income tax benefits from tax equity investments on the investor’s balance sheet and income statement. These required disclosures are included in Note 8—Variable Interest Entities. Adoption of this ASU did not have a material impact on our consolidated financial statements or disclosures. ASU 2022-03 – Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, Issued June 2022 The amendments in this ASU clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. This ASU also requires specific disclosures for equity securities subject to contractual sale restrictions. Adoption of this ASU did not have a material impact on our consolidated financial statements or disclosures.

(3) Other derivative contracts not designated as hedging instruments include risk participation agreements and equity warrants. (4) BancShares accounts for swap contracts cleared by the Chicago Mercantile Exchange and LCH Clearnet as “settled-to-market.” As a result, variation margin payments are characterized as settlement of the derivative exposure and variation margin balances are netted against the corresponding derivative mark-to-market balances. Gross amounts of recognized assets and liabilities were lowered by $83 million and $26 million, respectively, at March 31, 2024, which includes $0 million and $0 million relating to qualifying hedges, respectively. Gross amounts of recognized assets and liabilities were lowered by $66 million and $37 million, respectively, at December 31, 2023, which includes $4 million and $0 million relating to qualifying hedges, respectively. (5) BancShares’ derivative transactions are governed by International Swaps and Derivatives Association (“ISDA”) agreements that allow for net settlements of certain payments as well as offsetting of all contracts with a given counterparty in the event of bankruptcy or default of one of the two parties to the transaction. BancShares believes its ISDA agreements meet the definition of a master netting arrangement or similar agreement for purposes of the above disclosure. (6) In conjunction with the ISDA agreements described above, BancShares has entered into collateral arrangements with its counterparties, which provide for the exchange of cash depending on the change in the market valuation of the derivative contracts outstanding. Such collateral is available to be applied in settlement of the net balances upon an event of default of one of the counterparties. Collateral pledged or received is included in other assets or deposits, respectively.

(3) Other derivative contracts not designated as hedging instruments include risk participation agreements and equity warrants. (4) BancShares accounts for swap contracts cleared by the Chicago Mercantile Exchange and LCH Clearnet as “settled-to-market.” As a result, variation margin payments are characterized as settlement of the derivative exposure and variation margin balances are netted against the corresponding derivative mark-to-market balances. Gross amounts of recognized assets and liabilities were lowered by $83 million and $26 million, respectively, at March 31, 2024, which includes $0 million and $0 million relating to qualifying hedges, respectively. Gross amounts of recognized assets and liabilities were lowered by $66 million and $37 million, respectively, at December 31, 2023, which includes $4 million and $0 million relating to qualifying hedges, respectively. (5) BancShares’ derivative transactions are governed by International Swaps and Derivatives Association (“ISDA”) agreements that allow for net settlements of certain payments as well as offsetting of all contracts with a given counterparty in the event of bankruptcy or default of one of the two parties to the transaction. BancShares believes its ISDA agreements meet the definition of a master netting arrangement or similar agreement for purposes of the above disclosure. (6) In conjunction with the ISDA agreements described above, BancShares has entered into collateral arrangements with its counterparties, which provide for the exchange of cash depending on the change in the market valuation of the derivative contracts outstanding. Such collateral is available to be applied in settlement of the net balances upon an event of default of one of the counterparties. Collateral pledged or received is included in other assets or deposits, respectively.
