At March 31, 2024, our banking subsidiaries had pledged AFS securities consisting of U.S. Treasury securities with an aggregate fair value of $191 million as initial margin on interest rate swaps (see Notes 11 and 12). All of Schwab’s interest rate swaps are cleared through central counterparty (CCP) clearing houses which require the Company to post initial margin as collateral against potential losses. Initial margin is posted through futures commission merchants (FCM) which serve as the intermediary between the CCPs and Schwab. The FCM agreements governing our swaps allow for securities pledged as initial margin to be sold, repledged, or otherwise used by the FCM.

(2) For purposes of this table, unrealized losses on AFS securities excludes the unallocated PLM fair value hedge basis adjustments of $47 million and At March 31, 2024, substantially all rated securities in the investment portfolios were investment grade. U.S. agency mortgage-backed securities do not have explicit credit ratings; however, management considers these to be of the highest credit quality and rating given the guarantee of principal and interest by the U.S. government or U.S. government-sponsored enterprises. For a description of management’s quarterly evaluation of AFS securities in unrealized loss positions, see Item 8 – Note 2 in the 2023 Form 10-K. No amounts were recognized as credit loss expense and no securities were written down to fair value through earnings for the three months ended March 31, 2024 and the year ended December 31, 2023. None of the Company’s AFS securities held as of March 31, 2024 and December 31, 2023 had an allowance for credit losses. All HTM securities as of March 31, 2024 and December 31, 2023 were U.S. agency mortgage-backed securities and therefore had no allowance for credit losses because expected nonpayment of the amortized cost basis is zero. The Company had $531 million and $565 million of accrued interest for AFS and HTM securities as of March 31, 2024 and December 31, 2023, respectively. These amounts are excluded from the amortized cost basis and fair market value of AFS and HTM securities and included in other assets on the condensed consolidated balance sheets. There were no writeoffs of accrued interest receivable on AFS and HTM securities during the three months ended March 31, 2024, or for the year ended December 31, 2023.

(2) At March 31, 2024 and December 31, 2023, 42% and 43%, respectively, of the First Mortgage and HELOC portfolios were concentrated in California. These loans have performed in a manner consistent with the portfolio as a whole. (3) There were no loans accruing interest that were contractually 90 days or more past due at March 31, 2024 or December 31, 2023. At March 31, 2024, CSB had pledged the full balance of First Mortgages and HELOCs pursuant to a blanket lien status collateral arrangement to secure borrowing capacity on a secured credit facility with the FHLB (see Note 8). Changes in the allowance for credit losses on bank loans were as follows: Three Months Ended March 31, 2024 First Mortgages HELOCs Total residential real estate Pledged asset lines Other Total Balance at beginning of period $ 32 $ 2 $ 34 $ — $ 4 $ 38 Charge-offs — — — — — — Recoveries — — — — — — Provision for credit losses (5) (1) (6) — — (6) Balance at end of period $ 27 $ 1 $ 28 $ — $ 4 $ 32 March 31, 2023 Balance at beginning of period $ 66 $ 4 $ 70 $ — $ 3 $ 73 Charge-offs — — — — — — Recoveries — — — — — — Provision for credit losses 1 — 1 — — 1 Balance at end of period $ 67 $ 4 $ 71 $ — $ 3 $ 74 Consistent with Schwab’s loan charge-off policy for pledged asset lines (PALs) as disclosed in Item 8 – Note 2 of the 2023 Form 10-K, the Company charges off any unsecured balances no later than 90-days past due. As of March 31, 2024, substantially all PALs are also subject to the collateral maintenance practical expedient under ASC 326 Financial Instruments — Credit Losses . All PALs were fully collateralized by securities with fair values in excess of borrowings as of March 31, 2024 and December 31, 2023 and no allowance for credit losses for PALs as of those dates was required. The U.S. economy continued to be challenged by elevated inflation, tight monetary policy, and geopolitical unrest. However, amid sustained economic growth, supply and demand moved to a more balanced state. While the Federal Reserve held the policy rate steady during the first quarter of the year, management’s macroeconomic outlook reflects a near term continuation of elevated interest rates, with only a slight increase in unemployment and modest home price appreciation. Though higher mortgage rates are softening demand and reducing borrower affordability, we expect constrained housing supply will keep home prices relatively stable. Furthermore, credit quality metrics in the Company’s bank loans portfolio remain very strong and have improved in recent quarters. As a result of these factors, we decreased projected loss rates at March 31, 2024, as compared to December 31, 2023. Bank loan-related nonperforming assets consisted of nonaccrual loans of $15 million at both March 31, 2024 and Financial Instruments — Credit Losses: Troubled Debt Restructurings and Vintage Disclosures” on January 1, 2023. Credit Quality In addition to monitoring delinquency, Schwab monitors the credit quality of First Mortgages and HELOCs by stratifying the portfolios by the following: • Year of origination; • Borrower FICO scores at origination (Origination FICO); • Updated borrower FICO scores (Updated FICO); • Loan-to-value (LTV) ratios at origination (Origination LTV); and • Estimated Current LTV ratios (Estimated Current LTV). Borrowers’ FICO scores are provided by an independent third-party credit reporting service and generally updated quarterly. The Origination LTV and Estimated Current LTV for a HELOC include any first lien mortgage outstanding on the same property at the time of the HELOC’s origination. The Estimated Current LTV for each loan is updated on a monthly basis by reference to a home price appreciation index. The credit quality indicators of the Company’s First Mortgages and HELOCs are detailed below: First Mortgages Amortized Cost Basis by Origination Year March 31, 2024 2024 2023 2022 2021 2020 pre-2020 Total First Mortgages Revolving HELOCs amortized cost basis HELOCs converted to term loans Total HELOCs Origination FICO <620 $ — $ — $ 3 $ — $ 1 $ 1 $ 5 $ — $ — $ — 620 – 679 5 5 26 30 19 15 100 — 2 2 680 – 739 67 280 773 1,147 390 278 2,935 49 35 84 ≥740 559 2,205 5,185 10,304 3,505 1,403 23,161 250 119 369 Total $ 631 $ 2,490 $ 5,987 $ 11,481 $ 3,915 $ 1,697 $ 26,201 $ 299 $ 156 $ 455 Origination LTV ≤70% $ 453 $ 1,673 $ 4,434 $ 9,954 $ 3,257 $ 1,314 $ 21,085 $ 271 $ 109 $ 380 >70% – ≤90% 178 817 1,553 1,527 658 381 5,114 28 46 74 >90% – ≤100% — — — — — 2 2 — 1 1 Total $ 631 $ 2,490 $ 5,987 $ 11,481 $ 3,915 $ 1,697 $ 26,201 $ 299 $ 156 $ 455 Updated FICO <620 $ — $ 10 $ 15 $ 15 $ 16 $ 17 $ 73 $ 2 $ 6 $ 8 620 – 679 8 37 83 106 34 47 315 7 9 16 680 – 739 61 227 533 922 299 160 2,202 45 24 69 ≥740 562 2,216 5,356 10,438 3,566 1,473 23,611 245 117 362 Total $ 631 $ 2,490 $ 5,987 $ 11,481 $ 3,915 $ 1,697 $ 26,201 $ 299 $ 156 $ 455 Estimated Current LTV (1) ≤70% $ 457 $ 1,732 $ 4,838 $ 11,239 $ 3,894 $ 1,691 $ 23,851 $ 296 $ 155 $ 451 >70% – ≤90% 174 758 1,124 240 20 6 2,322 3 1 4 >90% – ≤100% — — 20 2 1 — 23 — — — >100% — — 5 — — — 5 — — — Total $ 631 $ 2,490 $ 5,987 $ 11,481 $ 3,915 $ 1,697 $ 26,201 $ 299 $ 156 $ 455 Gross charge-offs $ — $ — $ — $ — $ — $ — $ — $ — $ — $ — Percent of Loans on 0.01 % 0.01 % 0.02 % 0.01 % 0.01 % 0.39 % 0.04 % 0.13 % 2.36 % 0.88 % (1) Represents the LTV for the full line of credit (drawn and undrawn) for revolving HELOCs.

At March 31, 2024, First Mortgage loans of $21.6 billion had adjustable interest rates. Substantially all of these mortgages have initial fixed interest rates for three three At March 31, 2024 and December 31, 2023, Schwab had $161 million and $157 million, respectively, of accrued interest on bank loans, which is excluded from the amortized cost basis of bank loans and included in other assets on the condensed consolidated balance sheets. The HELOC product has a 30-year loan term with an initial draw period of ten years from the date of origination. After the initial draw period, the balance outstanding at such time is converted to a 20-year amortizing loan. The interest rate during the initial draw period and the 20-year amortizing period is a floating rate based on the prime rate plus a margin. The following table presents when current outstanding HELOCs will convert to amortizing loans: March 31, 2024 Balance Converted to an amortizing loan by period end (1) $ 156 Within 1 year 17 > 1 year – 3 years 38 > 3 years – 5 years 44 > 5 years 200 Total $ 455 (1) Includes $3 million of HELOCs converted to amortizing loans during the three months ended March 31, 2024. At March 31, 2024, $360 million of the HELOC portfolio was secured by second liens on the associated properties. Second lien mortgage loans typically possess a higher degree of credit risk given the subordination to the first lien holder in the event of default. In addition to the credit monitoring activities described previously, Schwab also monitors credit risk by reviewing the delinquency status of the first lien loan on the associated property. At March 31, 2024, the borrowers on approximately 59% of HELOC loan balances outstanding only paid the minimum amount due.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Variable Interest Entities As of March 31, 2024 and December 31, 2023, substantially all of Schwab’s involvement with variable interest entities (VIEs) was through CSB’s CRA-related investments and most of these are related to Low-Income Housing Tax Credit (LIHTC) investments. As part of CSB’s community reinvestment initiatives, CSB invests in funds that make equity investments in multifamily affordable housing properties and receives tax credits and other tax benefits for these investments. During the first quarters of 2024 and 2023, CSB recorded amortization of $42 million and $41 million, respectively, and recognized tax credits and other tax benefits of $53 million and $54 million, respectively, associated with these investments. The amortization, as well as the tax credits and other tax benefits, are included in taxes on income on the condensed consolidated statements of income. Tax credits and other tax benefits are reflected as cash flows from operating activities on the condensed consolidated statements of cash flows. Aggregate assets, liabilities, and maximum exposure to loss The aggregate assets, liabilities, and maximum exposure to loss from those VIEs in which Schwab holds a variable interest, but is not the primary beneficiary, are summarized in the table below: March 31, 2024 December 31, 2023 Aggregate Aggregate Maximum Aggregate Aggregate Maximum LIHTC investments (1) $ 1,467 $ 791 $ 1,467 $ 1,407 $ 759 $ 1,407 Other investments (2) 183 — 230 179 — 231 Total $ 1,650 $ 791 $ 1,697 $ 1,586 $ 759 $ 1,638 (1) Aggregate assets and aggregate liabilities are included in other assets and accrued expenses and other liabilities, respectively, on the condensed consolidated balance sheets. (2) Other investments include non-LIHTC CRA investments that are accounted for as loans at amortized cost, equity method investments, AFS securities, or using the adjusted cost method. Aggregate assets are included in AFS securities, bank loans – net, or other assets on the condensed consolidated balance sheets.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Loan Portfolio: CSB provides a co-branded loan origination program for CSB clients (the Program) with Rocket Mortgage, LLC (Rocket Mortgage ® ). Pursuant to the Program, Rocket Mortgage originates and services First Mortgages and HELOCs for CSB clients. Under the Program, CSB purchases certain First Mortgages and HELOCs that are originated by Rocket Mortgage. CSB purchased First Mortgages of $680 million and $723 million during the first quarters of 2024 and 2023, respectively. CSB purchased HELOCs with commitments of $36 million and $43 million during the first quarters of 2024 and 2023, respectively. The Company’s commitments to extend credit on lines of credit and to purchase First Mortgages are as follows: March 31, 2024 December 31, 2023 Commitments to extend credit related to unused HELOCs, PALs, and other lines of credit $ 2,567 $ 2,996 Commitments to purchase First Mortgage loans 443 351 Total $ 3,010 $ 3,347 Guarantees and indemnifications: Schwab has clients that sell (i.e., write) listed option contracts that are cleared by the Options Clearing Corporation – a clearing house that establishes margin requirements on these transactions. We satisfy the margin requirements of these transactions through pledging certain client securities. For additional information on these pledged securities, refer to Note 12. In connection with its securities lending activities, Schwab is required to provide collateral to certain brokerage clients. The Company satisfies the collateral requirements by providing cash as collateral. The Company also provides guarantees to securities clearing houses and exchanges under standard membership agreements, which require members to guarantee the performance of other members. Under the agreements, if another member becomes unable to satisfy its obligations to the clearing houses and exchanges, other members would be required to meet shortfalls. The Company’s liability under these arrangements is not quantifiable and may exceed the amounts it has posted as collateral. The Company also engages third-party firms to clear clients’ futures and options on futures transactions and to facilitate clients’ foreign exchange trading, and has agreed to indemnify these firms for any losses that they may incur from the client transactions introduced to them by the Company. The potential requirement for the Company to make payments under these arrangements is remote. Accordingly, no liability has been recognized for these guarantees. IDA agreement: On May 4, 2023, the Company executed the 2023 IDA agreement with the TD Depository Institutions that replaced and superseded the previous agreement dated November 24, 2019, as amended. The 2023 IDA agreement specifies responsibilities, including certain contingent obligations, of the Company going forward. Pursuant to the 2023 IDA agreement, uninvested cash within eligible brokerage client accounts is swept off-balance sheet to deposit accounts at the TD Depository Institutions. Schwab provides recordkeeping and support services to the TD Depository Institutions with respect to the deposit accounts for which Schwab receives an aggregate monthly fee. The Company’s ability to migrate these balances to its balance sheet is dependent on multiple factors including having sufficient capital levels to sustain these incremental deposits and certain binding limitations specified in the 2023 IDA agreement. During the first three months of 2024, Schwab did not move IDA balances to its balance sheet. The 2023 IDA agreement extends the agreement term to sweep balances to the TD Depository Institutions through July 1, 2034, and requires that Schwab maintain minimum and maximum IDA balances as follows: • Through September 10, 2025, Schwab must maintain minimum balances above the total of then-outstanding unmatured fixed-rate obligation amounts, with a maximum of $30 billion above this total amount. During this period, withdrawals of IDA balances by Schwab are generally permitted only to the extent of withdrawals initiated by Schwab customers, with limited exceptions, except to the extent necessary for Schwab to maintain balances below the applicable maximum. • After September 10, 2025, withdrawals of IDA balances are permitted at Schwab’s discretion, subject to an obligation to maintain IDA balances above a minimum of $60 billion, with a maximum of $90 billion. Designation of deposit balances for investment in fixed- or floating-rate instruments under the 2023 IDA agreement is at Schwab’s sole discretion with certain limitations on the amount of fixed-rate obligation amounts. If IDA balances decline below the required IDA balance minimum as described above, Schwab would be required to make a nonperformance payment to the TD Depository Institutions pursuant to the terms of the 2023 IDA agreement. Pursuant to the 2023 IDA agreement, in 2023, Schwab opted to buy down $5.0 billion of fixed-rate obligation amounts, incurring market-based fees of $249 million, which were capitalized as contract assets and included in other assets on the condensed consolidated balance sheet. For additional information on these contract assets, see Note 3. As of March 31, 2024, the total ending IDA balance was $90.3 billion, of which $79.2 billion was fixed-rate obligation amounts and $11.1 billion was floating-rate obligation amounts. As of December 31, 2023, the total ending IDA balance was $97.5 billion, of which $83.7 billion was fixed-rate obligation amounts and $13.8 billion was floating-rate obligation amounts. Legal contingencies: Schwab is subject to claims and lawsuits in the ordinary course of business, including arbitrations, class actions and other litigation, some of which include claims for substantial or unspecified damages. The Company is also the subject of inquiries, investigations, and proceedings by regulatory and other governmental agencies. Predicting the outcome of a litigation or regulatory matter is inherently difficult, requiring significant judgment and evaluation of various factors, including the procedural status of the matter and any recent developments; prior experience and the experience of others in similar cases; available defenses, including potential opportunities to dispose of a case on the merits or procedural grounds before trial (e.g., motions to dismiss or for summary judgment); the progress of fact discovery; the opinions of counsel and experts regarding potential damages; and potential opportunities for settlement and the status of any settlement discussions. It may not be reasonably possible to estimate a range of potential liability until the matter is closer to resolution – pending, for example, further proceedings, the outcome of key motions or appeals, or discussions among the parties. Numerous issues may have to be developed, such as discovery of important factual matters and determination of threshold legal issues, which may include novel or unsettled questions of law. Reserves are established or adjusted or further disclosure and estimates of potential loss are provided as the matter progresses and more information becomes available. Schwab believes it has strong defenses in all significant matters currently pending and is contesting liability and any damages claimed. Nevertheless, some of these matters may result in adverse judgments or awards, including penalties, injunctions or other relief, and the Company may also determine to settle a matter because of the uncertainty and risks of litigation. Described below are matters in which there is a reasonable possibility that a material loss could be incurred or where the matter may otherwise be of significant interest to stockholders. Unless otherwise noted, the Company is unable to provide a reasonable estimate of any potential liability given the stage of proceedings in the matter. With respect to all other pending matters, based on current information and consultation with counsel, it does not appear reasonably possible that the outcome of any such matter would be material to the financial condition, operating results, or cash flows of the Company. Corrente Antitrust Litigation : On June 6, 2022, CSC was sued in the U.S. District Court for the Eastern District of Texas on behalf of a putative class of customers who purchased or sold securities through CS&Co or TD Ameritrade, Inc. from October 26, 2020 to the present. The lawsuit alleges that CSC’s acquisition of Ameritrade violated Section 7 of the Clayton Act because it has resulted in an anticompetitive market for the execution of retail customer orders. Plaintiffs seek unspecified damages, as well as injunctive and other relief. A motion by the Company to dismiss the lawsuit was denied by the court on February 24, 2023, and discovery is proceeding. Ford Order Routing Litigation : On September 15, 2014, Ameritrade Holding, TD Ameritrade, Inc. and its former CEO, Frederick J. Tomczyk, were sued in the U.S. District Court for the District of Nebraska on behalf of a putative class of TD Ameritrade, Inc. clients alleging that defendants failed to seek best execution and made misrepresentations and omissions regarding its order routing practices. Plaintiff seeks unspecified damages and injunctive and other relief. On September 14, 2018, the District Court granted plaintiff’s motion for class certification, and defendants petitioned for an immediate appeal of the District Court’s class certification decision. On April 23, 2021, the U.S. Court of Appeals, 8th Circuit, issued a decision reversing the District Court’s certification of a class and remanding the case back to the District Court for further proceedings. Plaintiff renewed his motion for class certification, which the District Court granted on September 20, 2022. Defendants are appealing the District Court’s ruling before the U.S. Court of Appeals, 8th Circuit.

Restructuring and Related Activities [Abstract]
Exit and Other Related Liabilities	Exit and Other Related Liabilities Integration of Ameritrade The Company completed its acquisition of Ameritrade effective October 6, 2020 and integration work continued during the first three months of 2024. The Company expects to complete the remaining client transitions from Ameritrade to Schwab in a final transition group in May of 2024. The Company expects to continue to incur significant acquisition and integration-related costs and integration-related capital expenditures throughout the remaining integration process. Such costs have included, and are expected to continue to include, professional fees, such as legal, advisory, and accounting fees, compensation and benefits expenses for employees and contractors involved in the integration work, and costs for technology enhancements. The Company has also incurred exit and other related costs to attain anticipated synergies, which are primarily comprised of employee compensation and benefits such as severance pay, other termination benefits, and retention costs, as well as costs related to facility closures, such as accelerated amortization and depreciation or impairments of assets in those locations. Exit and other related costs are a component of the Company’s overall acquisition and integration-related spending, and support the Company’s ability to achieve integration objectives including expected synergies. Our estimates of the nature, amounts, and timing of recognition of acquisition and integration-related costs remain subject to change based on certain factors, including the duration and complexity of the remaining integration process and the continued uncertainty of the economic environment. More specifically, factors that could cause variability in our expected acquisition and integration-related costs as we prepare for the last transition group and remaining integration work include the level of employee attrition, the complexity to wind-down the operations of the Ameritrade broker-dealers and related technology, and real estate-related exit cost variability. Inclusive of costs recognized through March 31, 2024, Schwab currently expects to incur total exit and other related costs for the integration of Ameritrade ranging from $500 million to $600 million, consisting of employee compensation and benefits, facility exit costs, and certain other costs. During the three months ended March 31, 2024 and 2023, the Company recognized $3 million and $10 million of acquisition-related exit costs, respectively. The Company expects that remaining exit and other related costs will be incurred and charged to expense over the next 9 months, with some costs expected to be incurred after client transition to decommission duplicative platforms and complete integration work. In addition to ASC 420 Exit or Disposal Cost Obligations (ASC 420), certain of the costs associated with these activities are accounted for in accordance with ASC 360 Property, Plant and Equipment (ASC 360), ASC 712 Compensation — Nonretirement Post Employment Benefits (ASC 712), ASC 718 Compensation — Stock Compensation (ASC 718), and ASC 842 Leases (ASC 842).

Other With significant progress made in the integration of Ameritrade, the Company took incremental actions in 2023 to streamline its operations to prepare for post-integration, including through position eliminations and decreasing its real estate footprint. In order to achieve anticipated cost savings through these actions, the Company expects to incur exit and related costs, primarily related to employee compensation and benefits and facility exit costs, of approximately $500 million inclusive of costs recognized through March 31, 2024 as described below. The Company anticipates the remaining costs, primarily related to real estate, will be incurred during 2024. In addition to ASC 420, certain of the costs associated with these activities are accounted for in accordance with ASC 360, ASC 712, ASC 718, and ASC 842.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities Risk Management Objective of Using Derivatives The Company utilizes derivative instruments to manage interest rate risk exposures that arise from business activities related to changes in fair values or the receipt of future known and uncertain cash amounts due to changes in interest rates. The Company uses derivative instruments to manage changes in the fair values of, as well as changes in the amounts and/or timing of known or expected cash receipts related to, our AFS investment portfolio. For a description of how the Company accounts for derivative instruments, see Item 8 – Note 2 in the 2023 Form 10-K. For additional information on the basis of presentation for derivative instruments on the Company’s condensed consolidated balance sheets and related offsetting considerations, see Note 12. Cash flows associated with derivative instruments are reflected as cash flows from operating activities in the condensed consolidated statements of cash flows consistent with the treatment and nature of the items being hedged. Fair Value Hedges of Interest Rate Risk The Company is exposed to changes in the fair value of its fixed-rate AFS securities due to changes in benchmark interest rates. The Company uses cleared interest rate swaps to manage its exposure to changes in fair value on these instruments attributable to changes in the designated benchmark interest rate. Cleared interest rate swaps designated as fair value hedges involve the payment of fixed-rate amounts to a CCP in exchange for the Company receiving floating-rate payments over the life of the agreements without the exchange of the underlying notional amount. The Company had outstanding interest rate swaps with aggregate notional amounts of $8.9 billion at March 31, 2024 and December 31, 2023 that were designated as fair value hedges of interest rate risk. Fair Values of Derivative Instruments The table below presents the gross fair values of the Company’s interest rate swaps designated as hedging instruments on the condensed consolidated balance sheets: March 31, 2024 December 31, 2023 Assets Liabilities Assets Liabilities Interest rate swaps (1,2) $ 1 $ — $ — $ — (1) Derivative assets are included in other assets and derivative liabilities are included in accrued expenses and other liabilities on the condensed consolidated balance sheets. Derivative assets and liabilities as of December 31, 2023 were less than $500 thousand. (2) Includes reductions related to variation margin settlements. Settlements on derivative positions cleared through CCPs are reflected as reductions to the associated derivative asset and liability balances. As of March 31, 2024, there was a $241 million reduction of derivative assets related to variation margin settlements. As of December 31, 2023, there was an $87 million reduction of derivative assets and a $2 million reduction of derivative liabilities related to variation margin settlements. Effects of Fair Value Hedge Accounting The following amounts were recorded in AFS securities on the condensed consolidated balance sheets related to fair value hedges: March 31, 2024 December 31, 2023 Amortized cost of hedged AFS securities (1,2) $ 8,747 $ 8,765 Cumulative fair value hedging adjustment included in the amortized cost of hedged AFS securities (1,2) (242) (85) (1) Includes the amortized cost basis of closed portfolios of AFS securities used to designate hedging relationships in which the hedged item is the stated amount of assets in the closed portfolios anticipated to be outstanding for the designated hedge period. At March 31, 2024 and December 31, 2023 , t he amortized cost basis of the closed portfolios used in these hedging relationships was $2.1 billion, of which $1.6 billion was designated in a portfolio layer hedging relationship. The cumulative basis adjustments associated with these hedging relationships were a reduction of the amortized cost basis of the closed portfolios of $47 million and $19 million, respectively, at March 31, 2024 and December 31, 2023. (2) Excludes the amortized cost and fair value hedging adjustment of AFS securities for which hedge accounting has been discontinued. The cumulative amount of fair value hedging adjustments remaining for these securities was a reduction of the amortized cost basis of less than $500 thousand, which is recorded in AFS securities on the condensed consolidated balance sheets and amortized to interest revenue as a yield adjustment over the lives of the securities.

Offsetting [Abstract]
Financial Instruments Subject to Off-Balance Sheet Credit Risk	Financial Instruments Subject to Off-Balance Sheet Credit Risk Interest rate swaps: Schwab uses interest rate swaps to manage certain interest rate risk exposures. Schwab’s interest rate swaps are cleared through CCPs which require the Company to post initial margin as collateral against potential losses. Schwab pledges investment securities as collateral in order to meet the CCP’s initial margin requirements. Initial margin is posted through FCMs which serve as the intermediary between CCPs and Schwab. Our interest rate swaps are subject to enforceable master netting arrangements allowing a right of setoff within each FCM-CCP relationship; however, we do not net these positions. Therefore, interest rate swaps are presented gross in the condensed consolidated balance sheets. See Note 11 for additional information on the Company’s interest rate swaps. Resale agreements: Schwab enters into collateralized resale agreements principally with other broker-dealers, which could result in losses in the event the counterparty fails to purchase the securities held as collateral for the cash advanced and the fair value of the securities declines. To mitigate this risk, Schwab requires that the counterparty deliver securities to a custodian, to be held as collateral, with a fair value at or in excess of the resale price. Schwab also sets standards for the credit quality of the counterparty, monitors the fair value of the underlying securities as compared to the related receivable, including accrued interest, and requires additional collateral where deemed appropriate. The collateral provided under these resale agreements is utilized to meet obligations under broker-dealer client protection rules, which place limitations on our ability to access such segregated securities. For Schwab to repledge or sell this collateral, we would be required to deposit cash and/or securities of an equal amount into our segregated reserve bank accounts in order to meet our segregated cash and investments requirement. Schwab’s resale agreements as of March 31, 2024 and December 31, 2023 were not subject to master netting arrangements. Securities lending: Schwab loans brokerage client securities temporarily to other broker-dealers and clearing houses in connection with its securities lending activities and receives cash as collateral for the securities loaned. Increases in security prices may cause the fair value of the securities loaned to exceed the amount of cash received as collateral. In the event a counterparty to these transactions does not return the loaned securities or provide additional cash collateral, we may be exposed to the risk of acquiring the securities at prevailing market prices in order to satisfy our client obligations. Schwab mitigates this risk by requiring credit approvals for counterparties, monitoring the fair value of securities loaned, and requiring additional cash as collateral when necessary. In addition, most of our securities lending transactions are through a program with a clearing organization, which guarantees the return of cash to us. We also borrow securities from other broker-dealers to fulfill short sales by brokerage clients and deliver cash to the lender in exchange for the securities. The fair value of these borrowed securities was $1.8 billion and $1.5 billion at March 31, 2024 and December 31, 2023, respectively. Our securities lending transactions are subject to enforceable master netting arrangements with other broker-dealers; however, we do not net securities lending transactions. Therefore, the securities loaned and securities borrowed are presented gross in the condensed consolidated balance sheets. Repurchase agreements: Schwab enters into collateralized repurchase agreements with external financial institutions in which the Company sells securities and agrees to repurchase these securities on a specified future date at a stated repurchase price. These repurchase agreements are collateralized by investment securities with a fair value equal to or in excess of the secured borrowing liability. Decreases in security prices posted as collateral for repurchase agreements may require Schwab to transfer cash or additional securities deemed acceptable by the counterparty. To mitigate this risk, Schwab monitors the fair value of underlying securities pledged as collateral compared to the related liability. Our collateralized repurchase agreements with each external financial institution are considered to be enforceable master netting arrangements. However, we do not net these arrangements. As such, the secured short-term borrowings associated with these collateralized repurchase agreements are presented gross in the condensed consolidated balance sheets. The following table presents information about our interest rate swaps, resale agreements, securities lending, repurchase agreements, and other activity depicting the potential effect of rights of setoff between these recognized assets and liabilities.

Fair Values of Assets and Liabi

Fair Values of Assets and Liabilities	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Values of Assets and Liabilities	Fair Values of Assets and Liabilities Assets and liabilities measured at fair value on a recurring basis Schwab’s assets and liabilities measured at fair value on a recurring basis include: certain cash equivalents, certain investments segregated and on deposit for regulatory purposes, AFS securities, certain other assets, interest rate swaps and certain accrued expenses and other liabilities. The Company uses the market approach to determine the fair value of assets and liabilities. When available, the Company uses quoted prices in active markets to measure the fair value of assets and liabilities. Quoted prices for investments in exchange-traded securities represent end-of-day close prices published by exchanges. Quoted prices for money market funds and other mutual funds represent reported net asset values. When utilizing market data and bid-ask spread, the Company uses the price within the bid-ask spread that best represents fair value. When quoted prices in active markets do not exist, the Company uses prices obtained from independent third-party pricing services to measure the fair value of investment assets, and we generally obtain prices from three independent third-party pricing sources for such assets recorded at fair value. Our primary independent pricing service provides prices for our fixed income investments such as commercial paper; certificates of deposits; U.S. government and agency securities; state and municipal securities; corporate debt securities; asset-backed securities; foreign government agency securities; and non-agency commercial mortgage-backed securities. Such prices are based on observable trades, broker/dealer quotes, and discounted cash flows that incorporate observable information such as yields for similar types of securities (a benchmark interest rate plus observable spreads) and weighted-average maturity for the same or similar “to-be-issued” securities. We compare the prices obtained from the primary independent pricing service to the prices obtained from the additional independent pricing services to determine if the price obtained from the primary independent pricing service is reasonable. Schwab does not adjust the prices received from independent third-party pricing services unless such prices are inconsistent with the definition of fair value and result in material differences in the amounts recorded. Liabilities measured at fair value on a recurring basis include interest rate swaps, securities sold but not yet purchased, and repurchase liabilities related to client-held fractional shares of equities, ETFs, and other securities, which are included in other assets on the condensed consolidated balance sheets. The fair values of securities sold but not yet purchased are based on quoted market prices or other observable market data. The Company has elected the fair value option pursuant to ASC 825 Financial Instruments for the repurchase liabilities to match the measurement and accounting of the related client-held fractional shares. The fair values of the repurchase liabilities are based on quoted market prices or other observable market data consistent with the related client-held fractional shares. Unrealized gains and losses on client-held fractional shares offset the unrealized gains and losses on the corresponding repurchase liabilities, resulting in no impact to the condensed consolidated statements of income. The Company’s liabilities to repurchase client-held fractional shares do not have credit risk, and, as a result, the Company has not recognized any gains or losses in the condensed consolidated statements of income or comprehensive income attributable to instrument-specific credit risk for these repurchase liabilities. The repurchase liabilities are included in accrued expenses and other liabilities on the condensed consolidated balance sheets. The fair values of interest rate swaps are based on market observable interest rate yield curves. Fair value measurements are priced considering the coupon rate of the fixed leg of the contract and the variable coupon rate on the floating leg of the contract. Valuation is based on both spot and forward rates on the swap yield curve. The Company validates its valuations with counterparty quotations from CCPs. See Note 11 for additional information on the Company’s interest rate swaps. For a description of the fair value hierarchy and Schwab’s fair value methodologies, see Item 8 – Note 2 in the 2023 Form 10-K. The Company did not adjust prices received from the primary independent third-party pricing service at March 31, 2024 or December 31, 2023.

Earnings Per Share [Abstract]
Earnings Per Common Share	Earnings Per Common Share The Company has voting and nonvoting common stock outstanding. As the rights of the voting and nonvoting common stock are identical, except with respect to voting, the net income of the Company has been allocated on a proportionate basis to the two classes. Diluted earnings per share is calculated using the treasury stock method for outstanding stock options and non-vested restricted stock units and the if-converted method for nonvoting common stock. The if-converted method assumes conversion of all nonvoting common stock to common stock. For further details surrounding the EPS computation, see Item 8 – Note 25 in the 2023 Form 10-K. EPS under the basic and diluted computations for both common stock and nonvoting common stock are as follows: Three Months Ended 2024 2023 Common Nonvoting Common Nonvoting Basic earnings per share: Numerator Net income $ 1,324 $ 38 $ 1,559 $ 44 Preferred stock dividends and other (1) (108) (3) (68) (2) Net income available to common stockholders $ 1,216 $ 35 $ 1,491 $ 42 Denominator Weighted-average common shares outstanding — basic 1,774 51 1,783 51 Basic earnings per share $ .69 $ .69 $ .84 $ .84 Diluted earnings per share: Numerator Net income available to common stockholders $ 1,216 $ 35 $ 1,491 $ 42 Reallocation of net income available to common stockholders as a result of conversion of nonvoting to voting shares 35 — 42 — Allocation of net income available to common stockholders: $ 1,251 $ 35 $ 1,533 $ 42 Denominator Weighted-average common shares outstanding — basic 1,774 51 1,783 51 Conversion of nonvoting shares to voting shares 51 — 51 — Common stock equivalent shares related to stock incentive plans 6 — 8 — Weighted-average common shares outstanding — diluted (2) 1,831 51 1,842 51 Diluted earnings per share $ .68 $ .68 $ .83 $ .83 (1) Includes preferred stock dividends and undistributed earnings and dividends allocated to non-vested restricted stock units.

As of March 31, 2024, CSC was subject to a stress capital buffer of 2.5%. In addition, CSB is required to maintain a capital conservation buffer of 2.5%. CSC and CSB are also required to maintain a countercyclical capital buffer above the regulatory minimum risk-based capital ratios, which was zero for both periods presented. If a buffer falls below the minimum requirement, CSC and CSB would be subject to increasingly strict limits on capital distributions and discretionary bonus payments to executive officers.

N/A Not applicable. Based on its regulatory capital ratios at March 31, 2024, CSB is considered well capitalized (the highest category) under its respective regulatory capital rules. There are no conditions or events since March 31, 2024 that management believes have changed CSB’s capital category. At March 31, 2024, the balance sheets of Charles Schwab Premier Bank, SSB (CSPB) and Charles Schwab Trust Bank (Trust Bank) consisted primarily of investment securities, and the entities held total assets of $26.0 billion and $10.2 billion, respectively.

Segment Reporting [Abstract]
Segment Information	Segment Information Schwab’s two reportable segments are Investor Services and Advisor Services. Schwab structures the operating segments according to its clients and the services provided to those clients. The Investor Services segment provides retail brokerage, investment advisory, and banking and trust services to individual investors, and retirement plan services, as well as other corporate brokerage services, to businesses and their employees. The Advisor Services segment provides custodial, trading, banking and trust, and support services, as well as retirement business services, to independent RIAs, independent retirement advisors, and recordkeepers. Revenues and expenses are attributed to the two segments based on which segment services the client. Management evaluates the performance of the segments on a pre-tax basis. Segment assets and liabilities are not used for evaluating segment performance or in deciding how to allocate resources to segments. There are no revenues from transactions between the segments. Financial information for the segments is presented in the following table: Investor Services Advisor Services Total Three Months Ended March 31, 2024 2023 2024 2023 2024 2023 Net Revenues Net interest revenue $ 1,742 $ 2,033 $ 491 $ 737 $ 2,233 $ 2,770 Asset management and administration fees 947 805 401 313 1,348 1,118 Trading revenue 713 775 104 117 817 892 Bank deposit account fees 135 99 48 52 183 151 Other 135 151 24 34 159 185 Total net revenues 3,672 3,863 1,068 1,253 4,740 5,116 Expenses Excluding Interest 2,265 2,233 677 773 2,942 3,006 Income before taxes on income $ 1,407 $ 1,630 $ 391 $ 480 $ 1,798 $ 2,110

Accounting Policies [Abstract]
Basis of Presentation	These unaudited condensed consolidated financial statements have been prepared in conformity with GAAP, which require management to make certain estimates and assumptions that affect the reported amounts in the accompanying financial statements and in the related disclosures. These estimates are based on information available as of the date of the condensed consolidated financial statements. While management makes its best judgment, actual amounts or results could differ from these estimates. In the opinion of management, all normal, recurring adjustments have been included for a fair statement of this interim financial information. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto, included in Schwab’s 2023 Form 10-K.

Assets and liabilities measured at fair value on a recurring basis	Schwab’s assets and liabilities measured at fair value on a recurring basis include: certain cash equivalents, certain investments segregated and on deposit for regulatory purposes, AFS securities, certain other assets, interest rate swaps and certain accrued expenses and other liabilities. The Company uses the market approach to determine the fair value of assets and liabilities. When available, the Company uses quoted prices in active markets to measure the fair value of assets and liabilities. Quoted prices for investments in exchange-traded securities represent end-of-day close prices published by exchanges. Quoted prices for money market funds and other mutual funds represent reported net asset values. When utilizing market data and bid-ask spread, the Company uses the price within the bid-ask spread that best represents fair value. When quoted prices in active markets do not exist, the Company uses prices obtained from independent third-party pricing services to measure the fair value of investment assets, and we generally obtain prices from three independent third-party pricing sources for such assets recorded at fair value. Our primary independent pricing service provides prices for our fixed income investments such as commercial paper; certificates of deposits; U.S. government and agency securities; state and municipal securities; corporate debt securities; asset-backed securities; foreign government agency securities; and non-agency commercial mortgage-backed securities. Such prices are based on observable trades, broker/dealer quotes, and discounted cash flows that incorporate observable information such as yields for similar types of securities (a benchmark interest rate plus observable spreads) and weighted-average maturity for the same or similar “to-be-issued” securities. We compare the prices obtained from the primary independent pricing service to the prices obtained from the additional independent pricing services to determine if the price obtained from the primary independent pricing service is reasonable. Schwab does not adjust the prices received from independent third-party pricing services unless such prices are inconsistent with the definition of fair value and result in material differences in the amounts recorded. Liabilities measured at fair value on a recurring basis include interest rate swaps, securities sold but not yet purchased, and repurchase liabilities related to client-held fractional shares of equities, ETFs, and other securities, which are included in other assets on the condensed consolidated balance sheets. The fair values of securities sold but not yet purchased are based on quoted market prices or other observable market data. The Company has elected the fair value option pursuant to ASC 825 Financial Instruments for the repurchase liabilities to match the measurement and accounting of the related client-held fractional shares. The fair values of the repurchase liabilities are based on quoted market prices or other observable market data consistent with the related client-held fractional shares. Unrealized gains and losses on client-held fractional shares offset the unrealized gains and losses on the corresponding repurchase liabilities, resulting in no impact to the condensed consolidated statements of income. The Company’s liabilities to repurchase client-held fractional shares do not have credit risk, and, as a result, the Company has not recognized any gains or losses in the condensed consolidated statements of income or comprehensive income attributable to instrument-specific credit risk for these repurchase liabilities. The repurchase liabilities are included in accrued expenses and other liabilities on the condensed consolidated balance sheets. The fair values of interest rate swaps are based on market observable interest rate yield curves. Fair value measurements are priced considering the coupon rate of the fixed leg of the contract and the variable coupon rate on the floating leg of the contract. Valuation is based on both spot and forward rates on the swap yield curve. The Company validates its valuations with counterparty quotations from CCPs. See Note 11 for additional information on the Company’s interest rate swaps.
