Organization, Consolidation and Presentation of Financial Statements [Abstract]
Introduction and Basis of Presentation	Introduction and Basis of Presentation The Charles Schwab Corporation (CSC) is a savings and loan holding company and engages, through its subsidiaries, in wealth management, securities brokerage, banking, asset management, custody, and financial advisory services. Principal business subsidiaries of CSC include the following: • Charles Schwab & Co., Inc. (CS&Co), a securities broker-dealer; • Charles Schwab Bank, SSB (CSB), our principal banking entity; and • Charles Schwab Investment Management, Inc. (CSIM), the investment advisor for Schwab’s proprietary mutual funds (Schwab Funds ® ) and for Schwab’s exchange-traded funds (Schwab ETFs™). Unless otherwise indicated, the terms “Schwab,” “the Company,” “we,” “us,” or “our” mean CSC together with its consolidated subsidiaries. These unaudited condensed consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the U.S. (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 2019 Form 10-K. Reclassifications: Certain prior period amounts have been reclassified to conform to the current period presentation. Beginning in the first quarter of 2020, order flow revenue was reclassified from other revenue to trading revenue in the condensed consolidated statements of income. Beginning in the second quarter of 2020, acquired intangible assets — net was reclassified from other assets and presented separately in the condensed consolidated balance sheets. Prior period amounts have been reclassified to reflect these changes. The significant accounting policies are included in Note 2 in the 2019 Form 10-K. There have been no significant changes to these accounting policies during the first six months of 2020 , except as described in Note 2 below.

Accounting Changes and Error Corrections [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Cash and investments segregated and on deposit for regulatory purposes Pursuant to Rule 15c3-3 of the Securities Exchange Act of 1934 and other applicable regulations, Schwab maintains cash or qualified securities in segregated reserve accounts for the exclusive benefit of clients. Cash and investments segregated and on deposit for regulatory purposes include resale agreements, which are collateralized by U.S. Government and agency securities. Resale agreements are accounted for as collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. The Company obtains collateral with a market value equal to or in excess of the principal amount loaned and accrued interest under resale agreements. Collateral is valued daily by the Company, with additional collateral obtained to ensure full collateralization. Cash and investments segregated also include certificates of deposit and U.S. Government securities. Certificates of deposit and U.S. Government securities are recorded at fair value. Schwab applies the practical expedient based on collateral maintenance provisions under Accounting Standards Codification (ASC) 326, Financial Instruments – Credit Losses , in estimating an allowance for credit losses for resale agreements. This practical expedient can be applied for financial assets with collateral maintenance provisions requiring the borrower to continually adjust the amount of the collateral securing the financial assets as a result of fair value changes in the collateral. In accordance with the practical expedient, when the Company reasonably expects that borrowers (or counterparties, as applicable) will replenish the collateral as required, there is no expectation of credit losses when the collateral’s fair value is greater than the amortized cost of the financial asset. If the amortized cost exceeds the fair value of collateral, then credit losses are estimated only on the unsecured portion. Receivables from brokerage clients Receivables from brokerage clients include margin loans to securities brokerage clients and other trading receivables from clients. Margin loans are collateralized by client securities and are carried at the amount receivable, net of an allowance for credit losses. Collateral is required to be maintained at specified minimum levels at all times. The Company monitors margin levels and requires clients to provide additional collateral, or reduce margin positions, to meet minimum collateral requirements if the fair value of the collateral changes. Schwab applies the practical expedient based on collateral maintenance provisions in estimating an allowance for credit losses for margin loans. An allowance for credit losses on unsecured or partially secured receivables from brokerage clients is estimated based on the aging of those receivables. Unsecured balances due to confirmed fraud are reserved immediately. The Company’s policy is to charge off any delinquent margin loans, including the accrued interest on such loans, no later than at 90 days past due. Accrued interest charged off is recognized as credit loss expense and is included in other expenses in the condensed consolidated statements of income. Clients with margin loans have agreed to allow Schwab to pledge collateralized securities in accordance with federal regulations. The collateral is not reflected in the consolidated financial statements. The allowance for credit losses for receivables from brokerage clients and related activity were immaterial for all periods presented. AFS investment securities AFS investment securities are recorded at fair value and unrealized gains and losses, other than losses related to credit factors, are reported, net of taxes, in AOCI included in stockholders’ equity. Realized gains and losses from sales of AFS investment securities are determined on a specific identification basis and are included in other revenue. An AFS investment security is impaired if the fair value of the security is less than its amortized cost basis. Management evaluates AFS debt investment securities with unrealized losses to determine whether the security impairment has resulted from a credit loss or other factors. This evaluation is performed quarterly on an individual security basis. The evaluation of whether credit loss exists is inherently judgmental. This evaluation considers multiple factors including: the financial condition of the issuer; the payment structure of the security; external credit ratings; our internal credit ratings; the security’s market implied credit spread; for asset-backed securities, the amount of credit support provided by the structure of the security to absorb credit losses on the underlying collateral; recent events specific to the issuer and the issuer’s industry; and whether all scheduled principal and interest payments have been received. If management determines that the impairment of an AFS debt investment security (or a portion of the impairment) is related to credit losses, an allowance for credit losses will be recorded for that security through a charge to earnings. The allowance for credit losses is measured as the difference between the amortized cost and the present value of expected cash flows and is limited to the difference between amortized cost and the fair value of the security. The Company estimates credit losses on a discounted cash flow basis using the security’s effective interest rate. Changes in the allowance for credit losses will be recorded through earnings in the period of the change. If it is determined that the Company intends to sell the impaired security or if it is more likely than not that the Company will be required to sell such security before any anticipated recovery of the amortized cost basis, any allowance for credit losses of that security will be written off and the amortized cost basis of the security will be written down to fair value with any incremental impairment recorded through earnings. The Company excludes accrued interest from the fair value and the amortized cost basis of the AFS debt investment securities for the purposes of identifying and measuring impairment of the securities. AFS debt investment securities are placed on nonaccrual status on a timely basis and any accrued interest receivable is reversed through interest income. Securities borrowed and securities loaned Securities borrowed transactions require Schwab to deliver cash to the lender in exchange for securities; the receivables from these transactions are included in other assets on the condensed consolidated balance sheets. For securities loaned, Schwab receives collateral in the form of cash in an amount equal to or greater than the market value of securities loaned; the payables from these transactions are included in accrued expenses and other liabilities on the condensed consolidated balance sheets. The market value of securities borrowed and loaned are monitored, with additional collateral obtained or refunded to ensure full collateralization. Fees received or paid are recorded in interest revenue or interest expense. Schwab applies the practical expedient based on collateral maintenance provisions in estimating an allowance for credit losses for securities borrowed receivables. Bank loans and related allowance for credit losses Bank loans are recorded at their contractual principal amounts and include unamortized direct origination costs or net purchase discounts or premiums. Direct origination costs and premiums and discounts are recognized in interest revenue using the effective interest method over the contractual life of the loan and are adjusted for actual prepayments. Additionally, management estimates an allowance for credit losses, which is deducted from the amortized cost basis of loans to arrive at the amount expected to be collected. The bank loan portfolio includes three portfolio segments: residential real estate, pledged asset lines (PALs), and other loans. We use these segments when developing and documenting our methodology for determining the allowance for credit losses. Residential real estate portfolio segment is divided into two classes of financing receivables for purposes of monitoring and assessing credit risk: First Mortgages and HELOCs. Schwab records an allowance for credit losses through a charge to earnings based on our estimate of current expected credit losses for the existing portfolio. We review the allowance for credit losses quarterly, taking into consideration current economic conditions, reasonable and supportable forecasts, the composition of the existing loan portfolio, past loss experience, and any other risks inherent in the portfolio to ensure that the allowance for credit losses is maintained at an appropriate level. PALs are collateralized by marketable securities with liquid markets. Credit lines are over-collateralized and borrowers are required to maintain collateral at specified levels at all times. The required collateral levels are determined based on the type of security pledged. Additionally, collateral market value is monitored on a daily basis and a borrower’s credit line may be reduced or collateral may be liquidated if the collateral is in danger of falling below specified levels. As such, the credit loss inherent within this portfolio is limited. Schwab applies the practical expedient based on collateral maintenance provisions in estimating an allowance for credit losses for PALs. The methodology to establish an allowance for credit losses for residential real estate portfolio segment utilizes statistical models that estimate prepayments, defaults, and expected losses for this portfolio segment based on predicted behavior of individual loans within the segment. The methodology also evaluates concentrations in the classes of financing receivables, including loan products within those classes, year of origination, and geographical distribution of collateral. Expected credit losses are forecast using a loan-level simulation of the delinquency status of the loans over the term of the loans. The simulation starts with the current relevant risk indicators, including the current delinquent status of each loan, the estimated current LTV ratio (Estimated Current LTV) of each loan, the term and structure of each loan, current key interest rates including U.S. Treasury and LIBOR rates, and borrower FICO scores. The more significant variables in the simulation include delinquency roll rates, loss severity, housing prices, interest rates, and unemployment rate. Delinquency roll rates (i.e., the rates at which loans transition through delinquency stages and ultimately result in a loss) are estimated from our historical loss experience adjusted for current trends and market information, which includes current and forecast conditions. Loss severity (i.e., loss given default) estimates are based on our historical loss experience and market trends, both current and forecast. The loss severity estimate used in the allowance for credit loss methodology for HELOCs is higher than that used in the methodology for First Mortgages. Housing price trends are derived from historical home price indices and econometric forecasts of future home values. Factors affecting the home price index include housing inventory, unemployment, interest rates, and inflation expectations. Interest rate projections are based on the current term structure of interest rates and historical volatilities to project various possible future interest rate paths. The unemployment rate forecast is typically based on the recent consensus of regularly published economic surveys. Linear interpolation is applied to revert to long-term trends after the reasonable and supportable forecast period. The methodology described above results in loss factors that are applied to the amortized cost basis of loans, exclusive of accrued interest receivable, to determine the allowance for credit losses for First Mortgages and HELOCs. Management also estimates a liability for expected credit losses on the Company’s commitments to extend credit related to unused HELOCs and commitments to purchase first mortgages. See Note 10 for additional information on these commitments. The liability is calculated by applying the loss factors described above to the commitments expected to be funded and is included in accrued expenses and other liabilities on the condensed consolidated balance sheets. The liability for expected credit losses on these commitments and related activity were immaterial for all periods presented. Schwab considers loan modifications in which it makes an economic concession to a borrower experiencing financial difficulty to be troubled debt restructurings (TDRs). Nonaccrual and Nonperforming loans First Mortgages, HELOCs, PALs, and other loans are considered past due when a payment is due and unpaid for 30 days. Loans are placed on nonaccrual status upon becoming 90 days past due as to interest or principal (unless the loans are well-secured and in the process of collection), or when the full timely collection of interest or principal becomes uncertain, including loans to borrowers who have filed for bankruptcy. HELOC loans secured by a second lien are placed on non-accrual status if the associated first lien is 90 days or more delinquent, regardless of the payment status of the HELOC. When a loan is placed on nonaccrual status, the accrued interest receivable is written off by reversing interest income and the loan is accounted for on the cash or cost recovery method until qualifying for return to accrual status. Generally, a nonaccrual loan may be returned to accrual status when all delinquent interest and principal is repaid and the borrower demonstrates a sustained period of performance, or when the loan is both well-secured and in the process of collection and collectability is no longer doubtful. Loans on nonaccrual status and other real estate owned are considered nonperforming assets. Loan Charge-Offs The Company charges off a loan in the period that it is deemed uncollectible and records a reduction in the allowance for credit losses and the loan balance. Our charge-off policy for First Mortgage and HELOC loans is to assess the value of the property when the loan has been delinquent for 180 days or has been discharged in bankruptcy proceedings, regardless of whether the property is in foreclosure, and charge-off the amount of the loan balance in excess of the estimated current value of the underlying property less estimated costs to sell. The Company’s policy for PALs is to charge off any delinquent loans no later than at 90 days past due. New Accounting Standards Adoption of New Accounting Standards Standard Description Date of Adoption Effects on the Financial Statements or Other Significant Matters Accounting Standards Update (ASU) 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” Provides guidance for recognizing impairment of most debt instruments measured at amortized cost, including loans and HTM debt securities. Requires estimating current expected credit losses (CECL) over the remaining life of an instrument or a portfolio of instruments with similar risk characteristics based on relevant information about past events, current conditions, and reasonable forecasts. The initial estimate of, and the subsequent changes in, CECL will be recognized as credit loss expense through current earnings and will be reflected as an allowance for credit losses offsetting the carrying value of the financial instrument(s) on the balance sheet. Amends the other-than-temporary impairment (OTTI) model for AFS debt securities by requiring the use of an allowance, rather than directly reducing the carrying value of the security, and eliminating consideration of the length of time such security has been in an unrealized loss position as a factor in concluding whether a credit loss exists. Adoption requires modified retrospective transition through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the entity applies the new guidance except that a prospective transition is required for AFS debt securities for which an OTTI has been recognized prior to the effective date. January 1, 2020 The Company adopted CECL as of January 1, 2020 using the modified retrospective method. The adoption of CECL resulted in an immaterial increase in the Company’s allowance for credit losses and an increase in the liability for expected credit losses on commitments to extend credit, both primarily related to First Mortgages and HELOCs. The adoption impact was recorded as an adjustment to retained earnings as of the date of adoption. ASU 2018-15, “Intangibles– Goodwill and Other–Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force)” Aligns the criteria for capitalizing implementation costs for cloud computing arrangements (CCA) that are service contracts with internal-use software that is developed or purchased and CCAs that include an internal-use software license. This guidance requires that the capitalized implementation costs be recognized over the period of the CCA service contract, subject to impairment evaluation on an ongoing basis. The guidance prescribes the balance sheet, income statement, and statement of cash flow classification of the capitalized implementation costs and related amortization expense, and requires additional quantitative and qualitative disclosures. Adoption provides for retrospective or prospective application to all implementation costs incurred after the date of adoption. January 1, 2020 The Company adopted this guidance prospectively on January 1, 2020. As such, adoption had no impact on the Company’s financial statements. Historically, Schwab has expensed implementation costs as they are incurred for CCAs that are service contracts. Therefore, adopting this guidance will change the Company’s accounting treatment for these types of implementation costs going forward. New Accounting Standards Not Yet Adopted Standard Description Required Date of Adoption Effects on the Financial Statements or Other Significant Matters ASU 2020-4, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” Provides optional expedients and exceptions for applying existing accounting guidance to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met, including simplifying accounting analyses for contract modifications. This guidance only applies to the items listed above if they reference LIBOR or another reference rate expected to be discontinued because of reference rate reform and only for a limited period of time. When elected, the optional expedients for contract modifications must be applied consistently for all eligible contracts or eligible transactions subject to the same accounting guidance that would have otherwise been applied. Once elected, the amendments must be applied prospectively. N/A. Effective March 12, 2020 through December 31, 2022 The Company is evaluating the expedients and exceptions provided by this guidance. The elected amendments will be applied prospectively and the Company is currently evaluating the potential impacts on its consolidated financial statements.

Business Combinations [Abstract]
Business Acquisitions	Business Acquisitions USAA-IMCO On May 26, 2020, the Company completed its acquisition of the assets of USAA-IMCO for $1.6 billion in cash, subject to post-closing adjustments. Along with the asset purchase agreement, the companies entered into a long-term referral agreement that makes Schwab the exclusive provider of wealth management and investment brokerage services for USAA members. The USAA-IMCO acquisition adds scale to the Company’s operations through the addition of over one million brokerage and managed portfolio accounts with approximately $80 billion in client assets at the acquisition date. The transaction also provides Schwab the opportunity to further expand our client base by serving USAA’s members through the long-term referral agreement. The Company accounted for the USAA-IMCO acquisition as a business combination under GAAP and accordingly, the purchase price was allocated to the assets acquired and liabilities assumed based on their estimated fair values as of the date of acquisition. The determination of fair values requires management to make significant estimates and assumptions. The estimated fair values of the assets acquired and liabilities assumed are considered provisional and are based on currently available information. The Company believes that the information available provides a reasonable basis for estimating the fair values of assets acquired and liabilities assumed; however, these provisional estimates may be adjusted upon the availability of new information regarding facts and circumstances which existed at the acquisition date. The Company expects to finalize the valuation of assets and liabilities as soon as practicable, but not later than one year from the acquisition date. The following table summarizes the purchase price, provisional fair values of the assets acquired and liabilities assumed, and resulting goodwill as of the acquisition date. Purchase price $ 1,624 Fair value of assets acquired: Cash segregated and on deposit for regulatory purposes 4,392 Receivables from brokerage clients — net 80 Intangible assets 1,118 Total assets acquired 5,590 Fair value of liabilities assumed: Payables to brokerage clients 4,472 Total liabilities assumed 4,472 Fair value of net identifiable assets acquired 1,118 Goodwill $ 506 The provisional identifiable intangible assets of $1.1 billion are subject to amortization. The following table summarizes the major classes of intangible assets acquired and their respective weighted-average estimated useful lives. Estimated Fair Value Weighted-Average Estimated Useful Life (years) Customer relationships $ 962 18 Brokerage referral agreement (1) 151 20 Royalty-free license 5 7 Total intangible assets $ 1,118 (1) The brokerage referral agreement has an initial term of 5 years and is automatically renewable for one-year increments thereafter. The estimated fair values of customer relationships, the brokerage referral agreement, and the royalty-free license were estimated using the multi-period excess earnings, with-and-without, and relief from royalty methods, respectively. The multi-period excess earnings method starts with a forecast of all of the expected future net cash flows associated with the asset, and the relief from royalty method starts with a forecast of the royalties saved by the Company because it owns the asset. The with- and-without method quantifies the difference between forecasted cash flows with the asset and without the asset. The forecasts are then adjusted to present value b y applying an appropriate discount rate that reflects the risks associated with the cash flow streams. Goodwill recorded of $506 million , primarily attributable to the additional scale and anticipated synergies from the USAA-IMCO acquisition, was assigned to the Investor Services segment and will be deductible for tax purposes. The Company’s condensed consolidated statements of income include total net revenues and net loss attributable to the USAA-IMCO acquisition of $39 million and $ 37 million, respectively, for the period May 26, 2020 through June 30, 2020 . In connection with the acquisition, the Company agreed to reimburse USAA for certain contract termination fees and severance costs incurred by USAA. These costs totaled $19 million and $23 million for the three and six months ended June 30, 2020 , respectively, and are included in other expense on the condensed consolidated statements of income. Additionally, the Company incurred various professional fees and other costs related to the USAA-IMCO acquisition, such as advisory, legal, and accounting fees. In total, the Company incurred acquisition and integration-related costs of $ 39 million and $ 3 million for the three months ended June 30, 2020 and 2019 , respectively, and $ 54 million and $ 3 million for the six months ended June 30, 2020 and 2019 , respectively, which are primarily included in professional services and other expense on the condensed consolidated statements of income. Pro Forma Financial Information (Unaudited) The following table presents unaudited pro forma financial information as if the USAA-IMCO acquisition had occurred on January 1, 2019. The unaudited pro forma results reflect adjustments for acquisition and integration-related costs, amortization of acquired intangible assets, and their related income tax effects, and do not reflect potential revenue growth or cost savings that may be realized as a result of the acquisition. Pro forma net income for the three and six months ended June 30, 2020 excludes after-tax acquisition and integration-related costs of $30 million and $41 million , respectively. These costs and after-tax acquisition and integration-related costs of $10 million incurred in 2019 are included in pro forma net income for the six months ended June 30, 2019.

(2) As of June 30, 2020 approximately 49% of the total AFS, and as of December 31, 2019 approximately 32% , of the total AFS and HTM investments in corporate debt securities and commercial paper were issued by institutions in the financial services industry. (3) Included in cash and cash equivalents on the condensed consolidated balance sheets, but excluded from this table is $2.5 billion of AFS commercial paper as of December 31, 2019 ( none as of June 30, 2020). These holdings have maturities of three months or less and an aggregate market value equal to amortized cost. In October 2019, the Federal Reserve issued a final enhanced prudential standards rule, and the Federal Reserve, the Office of the Comptroller of the Currency, and the FDIC jointly issued a final regulatory capital and liquidity rule. With total consolidated assets of $294.0 billion at December 31, 2019, CSC is designated as a Category III firm pursuant to the framework established by the final rules. Accordingly, the Company opted to exclude AOCI from its regulatory capital as permitted by the regulatory capital and liquidity rule beginning January 1, 2020. In accordance with ASC 320 and as of January 1, 2020, the Company transferred all of its investment securities designated as HTM to the AFS category without tainting our intent to hold other debt securities to maturity. At the date of transfer, these securities had a total amortized cost of $134.7 billion and a total net unrealized gain of $1.4 billion . At June 30, 2020 , our banking subsidiaries had pledged securities with a fair value of $36.7 billion as collateral to secure borrowing capacity on secured credit facilities with the Federal Home Loan Bank (FHLB) (see Note 9).

(1) All PALs were fully collateralized by securities with fair values in excess of borrowings as of each period presented. Although continued economic uncertainty remains due to the ongoing COVID-19 pandemic, credit quality metrics and overall performance of the bank loans portfolios remain strong. Management’s reasonable and supportable forecast period extends through 2021, with unemployment peaking in the second quarter of 2020 accompanied by lackluster growth in home prices that do not revert to long-term trends until after 2021. Continued strong credit quality metrics and a modestly improving macroeconomic outlook produced a relatively stable projection of credit losses compared to the prior quarter. A summary of bank loan-related nonperforming assets and troubled debt restructurings is as follows: June 30, 2020 December 31, 2019 Nonaccrual loans (1) $ 23 $ 22 Other real estate owned (2) 1 1 Total nonperforming assets 24 23 Troubled debt restructurings 2 2 Total nonperforming assets and troubled debt restructurings $ 26 $ 25 (1) Nonaccrual loans include nonaccrual troubled debt restructurings. (2) Included in other assets on the condensed consolidated balance sheets. 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 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 bank loan portfolio are detailed below: First Mortgages Amortized Cost Basis by Origination Year June 30, 2020 2020 2019 2018 2017 2016 pre-2016 Total First Mortgages Revolving HELOCs amortized cost basis HELOCs converted to term loans Total HELOCs Origination FICO <620 $ — $ — $ — $ — $ — $ 2 $ 2 $ — $ — $ — 620 – 679 12 14 4 11 17 18 76 1 4 5 680 – 739 491 436 153 247 235 324 1,886 100 94 194 ≥740 4,116 3,130 712 1,218 1,434 1,419 12,029 434 348 782 Total $ 4,619 $ 3,580 $ 869 $ 1,476 $ 1,686 $ 1,763 $ 13,993 $ 535 $ 446 $ 981 Origination LTV ≤70% $ 3,866 $ 2,797 $ 612 $ 1,106 $ 1,429 $ 1,240 $ 11,050 $ 393 $ 314 $ 707 >70% – ≤90% 753 783 257 370 257 520 2,940 142 128 270 >90% – ≤100% — — — — — 3 3 — 4 4 Total $ 4,619 $ 3,580 $ 869 $ 1,476 $ 1,686 $ 1,763 $ 13,993 $ 535 $ 446 $ 981 Weighted Average <620 $ 4 $ 4 $ 2 $ 2 $ 4 $ 22 $ 38 $ 5 $ 13 $ 18 620 – 679 31 54 17 33 19 54 208 14 20 34 680 – 739 430 322 104 162 142 215 1,375 71 66 137 ≥740 4,154 3,200 746 1,279 1,521 1,472 12,372 445 347 792 Total $ 4,619 $ 3,580 $ 869 $ 1,476 $ 1,686 $ 1,763 $ 13,993 $ 535 $ 446 $ 981 Estimated Current LTV (1) ≤70% $ 3,912 $ 2,975 $ 744 $ 1,430 $ 1,671 $ 1,744 $ 12,476 $ 510 $ 427 $ 937 >70% – ≤90% 707 605 125 46 15 17 1,515 25 16 41 >90% – ≤100% — — — — — 1 1 — 2 2 >100% — — — — — 1 1 — 1 1 Total $ 4,619 $ 3,580 $ 869 $ 1,476 $ 1,686 $ 1,763 $ 13,993 $ 535 $ 446 $ 981 Percent of Loans on 0.07 % — 0.03 % 0.03 % 0.08 % 0.45 % 0.09 % 0.21 % 1.58 % 0.71 % (1) Represents the LTV for the full line of credit (drawn and undrawn) for revolving HELOCs.

At June 30, 2020 , First Mortgage loans of $12.4 billion had adjustable interest rates. Substantially all of these mortgages have initial fixed interest rates for three to ten years and interest rates that adjust annually thereafter. Approximately 25% of the balance of these mortgages consisted of loans with interest-only payment terms. The interest rates on approximately 75% of the balance of these interest-only loans are not scheduled to reset for three or more years. Schwab’s mortgage loans do not include interest terms described as temporary introductory rates below current market rates. At June 30, 2020 and December 31, 2019 , Schwab had $43 million and $46 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 HELOCs converted to amortizing loans during each period presented: Three Months Ended June 30, Six Months Ended June 30, 2020 2019 2020 2019 HELOCs converted to amortizing loans $ 8 $ 11 $ 18 $ 33 The following table presents when current outstanding HELOCs will convert to amortizing loans: June 30, 2020 Balance Converted to an amortizing loan by period end $ 446 Within 1 year 41 > 1 year – 3 years 86 > 3 years – 5 years 124 > 5 years 284 Total $ 981 At June 30, 2020 , $789 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 June 30, 2020 , the borrowers on approximately 52% of HELOC loan balances outstanding only paid the minimum amount due.

Variable Interest Entities [Abstract]
Variable Interest Entities	Variable Interest Entities As of June 30, 2020 and December 31, 2019 , all of Schwab’s involvement with variable interest entities (VIEs) is through CSB’s Community Reinvestment Act (CRA)-related investments and most of those 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. 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: June 30, 2020 December 31, 2019 Aggregate Aggregate Maximum Aggregate Aggregate Maximum LIHTC investments (1) $ 533 $ 269 $ 533 $ 516 $ 275 $ 516 Other CRA investments (2) 116 — 152 120 — 154 Total $ 649 $ 269 $ 685 $ 636 $ 275 $ 670 (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 CRA investments are recorded using either the adjusted cost method, equity method, held for investment loans at amortized cost, or as AFS securities. Aggregate assets are included in AFS securities, bank loans – net, or other assets on the condensed consolidated balance sheets. Schwab’s maximum exposure to loss would result from the loss of the investments, including any committed amounts. CSB’s funding of these remaining commitments is dependent upon the occurrence of certain conditions, and CSB expects to pay substantially all of these commitments between 2020 and 2023 . During the six months ended June 30, 2020 and year ended December 31, 2019

As of June 30, 2020 and December 31, 2019 , the collateral pledged provided a total borrowing capacity of $44.4 billion and $34.2 billion , respectively, of which no amounts were outstanding at the end of either period. As a condition of the FHLB borrowings, we are required to hold FHLB stock, which was recorded in other assets on the condensed consolidated balance sheets. The investment in FHLB was $47 million and $35 million at June 30, 2020 and December 31, 2019 , respectively. Additionally, our banking subsidiaries have access to funding through the Federal Reserve discount window. Amounts available are dependent upon the fair value of certain investment securities that are pledged as collateral. As of June 30, 2020 and December 31, 2019 , the collateral pledged provided total borrowing capacity of $8.8 billion and $8.5 billion , respectively, of which no amounts were outstanding at the end of either period. During the first quarter of 2020, CSB and CSPB became members of the Federal Reserve. As a condition of our Federal Reserve membership, we are required to hold Federal Reserve stock, which totaled $182 million at June 30, 2020.

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 Quicken Loans, Inc. (Quicken Loans ® ). Pursuant to the Program, Quicken Loans originates and services First Mortgages and HELOCs for CSB clients. Under the Program, CSB purchases certain First Mortgages and HELOCs that are originated by Quicken Loans. CSB purchased First Mortgages of $2.7 billion and $702 million during the second quarters of 2020 and 2019 , respectively, and $4.9 billion and $1.1 billion during the first six months of 2020 and 2019 , respectively. CSB purchased HELOCs with commitments of $133 million and $66 million during the second quarters of 2020 and 2019 , respectively, and $240 million and $128 million during the first six months of 2020 and 2019 , respectively. The Company’s commitments to extend credit on bank lines of credit and to purchase First Mortgages are as follows: June 30, 2020 December 31, 2019 Commitments to extend credit related to unused HELOCs, PALs, and other lines of credit $ 9,341 $ 10,753 Commitments to purchase First Mortgage loans 1,992 1,521 Total $ 11,333 $ 12,274 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 partially satisfy the margin requirements by arranging unsecured standby letter of credit agreements (LOCs), in favor of the Options Clearing Corporation, which are issued by several banks. At June 30, 2020 , the aggregate face amount of these LOCs totaled $20 million . There were no funds drawn under any of these LOCs at June 30, 2020 . 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. Schwab 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. Schwab’s liability under these arrangements is not quantifiable and may exceed the cash and securities it has posted as collateral. At June 30, 2020 , amounts posted as collateral with such clearing houses and exchanges included $242 million of U.S. Treasury securities, which are included in other assets on the condensed consolidated balance sheet. The potential requirement for the Company to make payments under these arrangements is remote. Accordingly, no liability has been recognized for these guarantees. Acquisition of TD Ameritrade: On November 25, 2019, CSC announced a definitive agreement to acquire TD Ameritrade in an all-stock transaction. At the time of announcement, TD Ameritrade had approximately twelve million brokerage accounts and $1.3 trillion in total client assets. Under the agreement, TD Ameritrade stockholders will receive 1.0837 CSC shares for each TD Ameritrade share. Based on the closing price of CSC common stock on November 20, 2019, the merger consideration represented approximately $26 billion . The transaction is expected to close in the second half of 2020, subject to satisfaction of closing conditions. During the second quarter of 2020 the Department of Justice completed its antitrust review of our proposed acquisition of TD Ameritrade, and both Schwab and TD Ameritrade stockholders voted to approve the acquisition. 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 of a material loss, or where the matter may otherwise be of significant interest to stockholders. Unless 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. Crago Order Routing Litigation : On July 13, 2016, a securities class action lawsuit was filed in the U.S. District Court for the Northern District of California on behalf of a putative class of customers executing equity orders through CS&Co. The lawsuit names CS&Co and CSC as defendants and alleges that an agreement under which CS&Co routed orders to UBS Securities LLC between July 13, 2011 and December 31, 2014 violated CS&Co’s duty to seek best execution. Plaintiffs seek unspecified damages, interest, injunctive and equitable relief, and attorneys’ fees and costs. After a first amended complaint was dismissed with leave to amend, plaintiffs filed a second amended complaint on August 14, 2017. Defendants again moved to dismiss, and in a decision issued December 5, 2017, the court denied the motion. Defendants have answered the complaint to deny all allegations, and are vigorously contesting the lawsuit. TD Ameritrade Acquisition Litigation : As disclosed previously, Schwab and TD Ameritrade have been responding to federal securities lawsuits and a Delaware fiduciary lawsuit relating to the proposed acquisition. Eight lawsuits challenging the sufficiency of disclosures in the Form S-4 Registration Statement (“Registration Statement”) concerning the acquisition were filed as follows: Kent v. TD Ameritrade Holding Corporation et al. , a putative class action filed March 18, 2020 in U.S. District Court for the District of Delaware (Schwab entities named); Stein v. TD Ameritrade Holding Corporation et al., filed March 23, 2020 in U.S. District Court for the District of Delaware; Roth v. TD Ameritrade Holding Corporation et al. , filed March 30, 2020 in United States District Court for the District of New Jersey; Litwin v. TD Ameritrade Holding Corporation et al. , filed April 2, 2020 in U.S. District Court for the District of New Jersey; Bernstein v. TD Ameritrade Holding Corporation et al. , a putative class action filed April 6, 2020 in U.S. District Court for the District of New Jersey (CSC named); Garrison v. TD Ameritrade Holding Corporation et al. , filed April 6, 2020 in U.S District Court for the Southern District of New York; Paine-Mantha v. TD Ameritrade Holding Corporation et al ., filed May 12, 2020 in U.S. District Court for the District of Delaware; and Kong v. TD Ameritrade Holding Corporation et al ., filed May 15, 2020 in U.S. District Court for the District of New Jersey. Although TD Ameritrade and Schwab disputed the allegations, to avoid any unnecessary delays and the expense and distraction of litigation, TD Ameritrade voluntarily provided supplemental disclosures to the Registration Statement. As a result, plaintiffs in all eight cases have voluntarily dismissed their claims. On May 12, 2020, a lawsuit challenging the acquisition was filed in the Delaware Court of Chancery ( Hawkes v. Bettino et al. ) on behalf of a proposed class of TD Ameritrade’s stockholders, excluding, among others, the Toronto-Dominion Bank (TD Bank). The complaint names as defendants each member of the TD Ameritrade board of directors at the time the acquisition was approved, as well as TD Bank and Schwab. As an initial matter, the lawsuit sought to enjoin voting on or consummation of the acquisition, specifically alleging that prior to the TD Ameritrade board’s approval of the acquisition, agreements were reached between Schwab and TD Bank on an amendment of the Insured Deposit Account Agreement and voting of TD Bank’s shares of TD Ameritrade common stock in favor of the acquisition; which agreements allegedly caused Schwab to become an “interested stockholder” of TD Ameritrade under Section 203 of the Delaware General Corporation Law; and which would thereby require the affirmative vote of at least 66 2/3% of the outstanding TD Ameritrade common stock not allegedly owned by Schwab under Section 203. Subsequent to filing of the lawsuit and as previously disclosed, defendants reached an agreement with plaintiff under which plaintiff agreed to withdraw his Section 203 claim if the acquisition were to receive the 66 2/3% stockholder support allegedly required.

Offsetting [Abstract]
Financial Instruments Subject to Off-Balance Sheet Credit Risk	Financial Instruments Subject to Off-Balance Sheet Credit Risk 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 investment requirement. Schwab’s resale agreements are not subject to master netting arrangements. Securities lending: Schwab loans brokerage client securities temporarily to other brokers 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 the 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. 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 $556 million and $719 million at June 30, 2020 and December 31, 2019 , respectively. Most of our securities lending transactions are through a program with a clearing organization, which guarantees the return of cash to us. 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. The following table presents information about our resale agreements and securities lending activity depicting the potential effect of rights of setoff between these recognized assets and recognized liabilities.

The cash collateral received from counterparties under securities lending transactions was equal to or greater than the market value of the securities loaned at June 30, 2020 and December 31, 2019 . (5) Securities loaned are predominantly comprised of equity securities held in client brokerage accounts with overnight and continuous remaining contractual maturities. Margin lending: Clients with margin loans have agreed to allow Schwab to pledge collateralized securities in their brokerage accounts in accordance with federal regulations. The following table summarizes the fair value of client securities that were available, under such regulations, that could have been used as collateral, as well as the fair value of securities that we had pledged under such regulations and from securities borrowed transactions: June 30, 2020 December 31, 2019 Fair value of client securities available to be pledged $ 26,170 $ 26,685 Fair value of securities pledged for: Fulfillment of requirements with the Options Clearing Corporation (1) $ 4,056 $ 2,171 Fulfillment of client short sales 3,279 2,293 Securities lending to other broker-dealers 1,277 1,017 Total collateral pledged $ 8,612 $ 5,481 Note: Excludes amounts available and pledged for securities lending from fully-paid client securities.

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, and certain other assets. 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. We generally obtain prices from three independent third-party pricing sources for assets recorded at fair value. Our primary independent pricing service provides prices for our fixed income investments such as commercial paper; certificates of deposit; 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. For a description of the fair value hierarchy and Schwab’s fair value methodologies, see Note 2 in the 2019 Form 10-K. The Company did not adjust prices received from the primary independent third-party pricing service at June 30, 2020 or December 31, 2019 . Assets and Liabilities Measured at Fair Value on a Recurring Basis The following tables present the fair value hierarchy for assets measured at fair value on a recurring basis.

Therefore, AOCI is excluded from the amounts and ratios presented as of March 31, 2020. In 2019, CSC and CSB were required to include all components of AOCI in regulatory capital; the amounts and ratios for December 31, 2019 are presented on this basis. (2) Under the Basel III capital rule, CSC and CSB are also required to maintain a capital conservation buffer and a countercyclical capital buffer above the regulatory minimum risk-based capital ratios. The capital conservation buffer and countercyclical capital buffer were 2.5% and zero percent, respectively, for both periods presented. If either buffer falls below the minimum requirement, the Company would be subject to limits on capital distributions and discretionary bonus payments to executive officers. At June 30, 2020 , the minimum capital requirement plus capital conservation buffer and countercyclical capital buffer for Common Equity Tier 1 Risk-Based Capital, Tier 1 Risk-Based Capital, and Total Risk-Based Capital ratios were 7.0%, 8.5%, and 10.5%, respectively. N/A Not applicable. Based on its regulatory capital ratios at June 30, 2020 , CSB is considered well capitalized (the highest category) under its respective regulatory capital rules. There are no conditions or events since June 30, 2020 that management believes have changed CSB’s capital category. At June 30, 2020 , the balance sheets of CSPB and Charles Schwab Trust Bank (Trust Bank) consisted primarily of investment securities, and the entities held total assets of $26.0 billion and $11.2 billion , respectively. Based on their regulatory capital ratios, at June 30, 2020 , CSPB and Trust Bank are considered well capitalized under their respective regulatory capital rules. Net capital and net capital requirements for CS&Co are as follows: June 30, 2020 December 31, 2019 Net Capital $ 2,041 $ 3,700 Minimum net capital required 0.250 0.250 2% of aggregate debit balances 471 446 Net Capital in excess of required net capital $ 1,570 $ 3,254 Pursuant to Rule 15c3-3 of the Securities Exchange Act of 1934 and other applicable regulations, Schwab had cash and investments segregated for the exclusive benefit of clients at June 30, 2020 . The SEC Customer Protection Rule requires broker-dealers to segregate client fully-paid securities and cash balances not collateralizing margin positions and not swept to money market funds or bank deposit accounts. Amounts included in cash and investments segregated and on deposit for regulatory purposes represent actual balances on deposit. Cash and cash equivalents included in cash and investments segregated and on deposit for regulatory purposes are presented as part of Schwab’s cash balances in the condensed consolidated statements of cash flows.

The Investor Services segment provides retail brokerage and banking 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 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 June 30, 2020 2019 2020 2019 2020 2019 Net Revenues Net interest revenue $ 952 $ 1,154 $ 437 $ 455 $ 1,389 $ 1,609 Asset management and administration fees 583 560 218 226 801 786 Trading revenue (1) 138 140 55 67 193 207 Other (1) 51 37 16 42 67 79 Total net revenues 1,724 1,891 726 790 2,450 2,681 Expenses Excluding Interest 1,168 1,057 394 388 1,562 1,445 Income before taxes on income $ 556 $ 834 $ 332 $ 402 $ 888 $ 1,236 Investor Services Advisor Services Total Six Months Ended June 30, 2020 2019 2020 2019 2020 2019 Net Revenues Net interest revenue $ 2,080 $ 2,349 $ 881 $ 941 $ 2,961 $ 3,290 Asset management and administration fees 1,183 1,093 445 448 1,628 1,541 Trading revenue (1) 257 281 124 143 381 424 Other (1) 71 79 26 70 97 149 Total net revenues 3,591 3,802 1,476 1,602 5,067 5,404 Expenses Excluding Interest 2,322 2,119 810 785 3,132 2,904 Income before taxes on income $ 1,269 $ 1,683 $ 666 $ 817 $ 1,935 $ 2,500 (1) Beginning in the first quarter of 2020, order flow revenue was reclassified from other revenue to trading revenue.

Accounting Changes and Error Corrections [Abstract]
Basis of Presentation	These unaudited condensed consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the U.S. (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 2019 Form 10-K.
Reclassifications	Reclassifications: Certain prior period amounts have been reclassified to conform to the current period presentation. Beginning in the first quarter of 2020, order flow revenue was reclassified from other revenue to trading revenue in the condensed consolidated statements of income. Beginning in the second quarter of 2020, acquired intangible assets — net was reclassified from other assets and presented separately in the condensed consolidated balance sheets. Prior period amounts have been reclassified to reflect these changes.
Credit Loss, Financial Instrument	Cash and investments segregated and on deposit for regulatory purposes Pursuant to Rule 15c3-3 of the Securities Exchange Act of 1934 and other applicable regulations, Schwab maintains cash or qualified securities in segregated reserve accounts for the exclusive benefit of clients. Cash and investments segregated and on deposit for regulatory purposes include resale agreements, which are collateralized by U.S. Government and agency securities. Resale agreements are accounted for as collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. The Company obtains collateral with a market value equal to or in excess of the principal amount loaned and accrued interest under resale agreements. Collateral is valued daily by the Company, with additional collateral obtained to ensure full collateralization. Cash and investments segregated also include certificates of deposit and U.S. Government securities. Certificates of deposit and U.S. Government securities are recorded at fair value. Schwab applies the practical expedient based on collateral maintenance provisions under Accounting Standards Codification (ASC) 326, Financial Instruments – Credit Losses , in estimating an allowance for credit losses for resale agreements. This practical expedient can be applied for financial assets with collateral maintenance provisions requiring the borrower to continually adjust the amount of the collateral securing the financial assets as a result of fair value changes in the collateral. In accordance with the practical expedient, when the Company reasonably expects that borrowers (or counterparties, as applicable) will replenish the collateral as required, there is no expectation of credit losses when the collateral’s fair value is greater than the amortized cost of the financial asset. If the amortized cost exceeds the fair value of collateral, then credit losses are estimated only on the unsecured portion. Receivables from brokerage clients Receivables from brokerage clients include margin loans to securities brokerage clients and other trading receivables from clients. Margin loans are collateralized by client securities and are carried at the amount receivable, net of an allowance for credit losses. Collateral is required to be maintained at specified minimum levels at all times. The Company monitors margin levels and requires clients to provide additional collateral, or reduce margin positions, to meet minimum collateral requirements if the fair value of the collateral changes. Schwab applies the practical expedient based on collateral maintenance provisions in estimating an allowance for credit losses for margin loans. An allowance for credit losses on unsecured or partially secured receivables from brokerage clients is estimated based on the aging of those receivables. Unsecured balances due to confirmed fraud are reserved immediately. The Company’s policy is to charge off any delinquent margin loans, including the accrued interest on such loans, no later than at 90 days past due. Accrued interest charged off is recognized as credit loss expense and is included in other expenses in the condensed consolidated statements of income. Clients with margin loans have agreed to allow Schwab to pledge collateralized securities in accordance with federal regulations. The collateral is not reflected in the consolidated financial statements. The allowance for credit losses for receivables from brokerage clients and related activity were immaterial for all periods presented. AFS investment securities AFS investment securities are recorded at fair value and unrealized gains and losses, other than losses related to credit factors, are reported, net of taxes, in AOCI included in stockholders’ equity. Realized gains and losses from sales of AFS investment securities are determined on a specific identification basis and are included in other revenue. An AFS investment security is impaired if the fair value of the security is less than its amortized cost basis. Management evaluates AFS debt investment securities with unrealized losses to determine whether the security impairment has resulted from a credit loss or other factors. This evaluation is performed quarterly on an individual security basis. The evaluation of whether credit loss exists is inherently judgmental. This evaluation considers multiple factors including: the financial condition of the issuer; the payment structure of the security; external credit ratings; our internal credit ratings; the security’s market implied credit spread; for asset-backed securities, the amount of credit support provided by the structure of the security to absorb credit losses on the underlying collateral; recent events specific to the issuer and the issuer’s industry; and whether all scheduled principal and interest payments have been received. If management determines that the impairment of an AFS debt investment security (or a portion of the impairment) is related to credit losses, an allowance for credit losses will be recorded for that security through a charge to earnings. The allowance for credit losses is measured as the difference between the amortized cost and the present value of expected cash flows and is limited to the difference between amortized cost and the fair value of the security. The Company estimates credit losses on a discounted cash flow basis using the security’s effective interest rate. Changes in the allowance for credit losses will be recorded through earnings in the period of the change. If it is determined that the Company intends to sell the impaired security or if it is more likely than not that the Company will be required to sell such security before any anticipated recovery of the amortized cost basis, any allowance for credit losses of that security will be written off and the amortized cost basis of the security will be written down to fair value with any incremental impairment recorded through earnings. The Company excludes accrued interest from the fair value and the amortized cost basis of the AFS debt investment securities for the purposes of identifying and measuring impairment of the securities. AFS debt investment securities are placed on nonaccrual status on a timely basis and any accrued interest receivable is reversed through interest income. Securities borrowed and securities loaned Securities borrowed transactions require Schwab to deliver cash to the lender in exchange for securities; the receivables from these transactions are included in other assets on the condensed consolidated balance sheets. For securities loaned, Schwab receives collateral in the form of cash in an amount equal to or greater than the market value of securities loaned; the payables from these transactions are included in accrued expenses and other liabilities on the condensed consolidated balance sheets. The market value of securities borrowed and loaned are monitored, with additional collateral obtained or refunded to ensure full collateralization. Fees received or paid are recorded in interest revenue or interest expense. Schwab applies the practical expedient based on collateral maintenance provisions in estimating an allowance for credit losses for securities borrowed receivables. Bank loans and related allowance for credit losses Bank loans are recorded at their contractual principal amounts and include unamortized direct origination costs or net purchase discounts or premiums. Direct origination costs and premiums and discounts are recognized in interest revenue using the effective interest method over the contractual life of the loan and are adjusted for actual prepayments. Additionally, management estimates an allowance for credit losses, which is deducted from the amortized cost basis of loans to arrive at the amount expected to be collected. The bank loan portfolio includes three portfolio segments: residential real estate, pledged asset lines (PALs), and other loans. We use these segments when developing and documenting our methodology for determining the allowance for credit losses. Residential real estate portfolio segment is divided into two classes of financing receivables for purposes of monitoring and assessing credit risk: First Mortgages and HELOCs. Schwab records an allowance for credit losses through a charge to earnings based on our estimate of current expected credit losses for the existing portfolio. We review the allowance for credit losses quarterly, taking into consideration current economic conditions, reasonable and supportable forecasts, the composition of the existing loan portfolio, past loss experience, and any other risks inherent in the portfolio to ensure that the allowance for credit losses is maintained at an appropriate level. PALs are collateralized by marketable securities with liquid markets. Credit lines are over-collateralized and borrowers are required to maintain collateral at specified levels at all times. The required collateral levels are determined based on the type of security pledged. Additionally, collateral market value is monitored on a daily basis and a borrower’s credit line may be reduced or collateral may be liquidated if the collateral is in danger of falling below specified levels. As such, the credit loss inherent within this portfolio is limited. Schwab applies the practical expedient based on collateral maintenance provisions in estimating an allowance for credit losses for PALs. The methodology to establish an allowance for credit losses for residential real estate portfolio segment utilizes statistical models that estimate prepayments, defaults, and expected losses for this portfolio segment based on predicted behavior of individual loans within the segment. The methodology also evaluates concentrations in the classes of financing receivables, including loan products within those classes, year of origination, and geographical distribution of collateral. Expected credit losses are forecast using a loan-level simulation of the delinquency status of the loans over the term of the loans. The simulation starts with the current relevant risk indicators, including the current delinquent status of each loan, the estimated current LTV ratio (Estimated Current LTV) of each loan, the term and structure of each loan, current key interest rates including U.S. Treasury and LIBOR rates, and borrower FICO scores. The more significant variables in the simulation include delinquency roll rates, loss severity, housing prices, interest rates, and unemployment rate. Delinquency roll rates (i.e., the rates at which loans transition through delinquency stages and ultimately result in a loss) are estimated from our historical loss experience adjusted for current trends and market information, which includes current and forecast conditions. Loss severity (i.e., loss given default) estimates are based on our historical loss experience and market trends, both current and forecast. The loss severity estimate used in the allowance for credit loss methodology for HELOCs is higher than that used in the methodology for First Mortgages. Housing price trends are derived from historical home price indices and econometric forecasts of future home values. Factors affecting the home price index include housing inventory, unemployment, interest rates, and inflation expectations. Interest rate projections are based on the current term structure of interest rates and historical volatilities to project various possible future interest rate paths. The unemployment rate forecast is typically based on the recent consensus of regularly published economic surveys. Linear interpolation is applied to revert to long-term trends after the reasonable and supportable forecast period. The methodology described above results in loss factors that are applied to the amortized cost basis of loans, exclusive of accrued interest receivable, to determine the allowance for credit losses for First Mortgages and HELOCs. Management also estimates a liability for expected credit losses on the Company’s commitments to extend credit related to unused HELOCs and commitments to purchase first mortgages. See Note 10 for additional information on these commitments. The liability is calculated by applying the loss factors described above to the commitments expected to be funded and is included in accrued expenses and other liabilities on the condensed consolidated balance sheets. The liability for expected credit losses on these commitments and related activity were immaterial for all periods presented. Schwab considers loan modifications in which it makes an economic concession to a borrower experiencing financial difficulty to be troubled debt restructurings (TDRs). Nonaccrual and Nonperforming loans First Mortgages, HELOCs, PALs, and other loans are considered past due when a payment is due and unpaid for 30 days. Loans are placed on nonaccrual status upon becoming 90 days past due as to interest or principal (unless the loans are well-secured and in the process of collection), or when the full timely collection of interest or principal becomes uncertain, including loans to borrowers who have filed for bankruptcy. HELOC loans secured by a second lien are placed on non-accrual status if the associated first lien is 90 days or more delinquent, regardless of the payment status of the HELOC. When a loan is placed on nonaccrual status, the accrued interest receivable is written off by reversing interest income and the loan is accounted for on the cash or cost recovery method until qualifying for return to accrual status. Generally, a nonaccrual loan may be returned to accrual status when all delinquent interest and principal is repaid and the borrower demonstrates a sustained period of performance, or when the loan is both well-secured and in the process of collection and collectability is no longer doubtful. Loans on nonaccrual status and other real estate owned are considered nonperforming assets. Loan Charge-Offs The Company charges off a loan in the period that it is deemed uncollectible and records a reduction in the allowance for credit losses and the loan balance. Our charge-off policy for First Mortgage and HELOC loans is to assess the value of the property when the loan has been delinquent for 180 days or has been discharged in bankruptcy proceedings, regardless of whether the property is in foreclosure, and charge-off the amount of the loan balance in excess of the estimated current value of the underlying property less estimated costs to sell. The Company’s policy for PALs is to charge off any delinquent loans no later than at 90 days past due.
Adoption of New Accounting Standards and New Accounting Standards Not Yet Adopted	Adoption of New Accounting Standards Standard Description Date of Adoption Effects on the Financial Statements or Other Significant Matters Accounting Standards Update (ASU) 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” Provides guidance for recognizing impairment of most debt instruments measured at amortized cost, including loans and HTM debt securities. Requires estimating current expected credit losses (CECL) over the remaining life of an instrument or a portfolio of instruments with similar risk characteristics based on relevant information about past events, current conditions, and reasonable forecasts. The initial estimate of, and the subsequent changes in, CECL will be recognized as credit loss expense through current earnings and will be reflected as an allowance for credit losses offsetting the carrying value of the financial instrument(s) on the balance sheet. Amends the other-than-temporary impairment (OTTI) model for AFS debt securities by requiring the use of an allowance, rather than directly reducing the carrying value of the security, and eliminating consideration of the length of time such security has been in an unrealized loss position as a factor in concluding whether a credit loss exists. Adoption requires modified retrospective transition through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the entity applies the new guidance except that a prospective transition is required for AFS debt securities for which an OTTI has been recognized prior to the effective date. January 1, 2020 The Company adopted CECL as of January 1, 2020 using the modified retrospective method. The adoption of CECL resulted in an immaterial increase in the Company’s allowance for credit losses and an increase in the liability for expected credit losses on commitments to extend credit, both primarily related to First Mortgages and HELOCs. The adoption impact was recorded as an adjustment to retained earnings as of the date of adoption. ASU 2018-15, “Intangibles– Goodwill and Other–Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force)” Aligns the criteria for capitalizing implementation costs for cloud computing arrangements (CCA) that are service contracts with internal-use software that is developed or purchased and CCAs that include an internal-use software license. This guidance requires that the capitalized implementation costs be recognized over the period of the CCA service contract, subject to impairment evaluation on an ongoing basis. The guidance prescribes the balance sheet, income statement, and statement of cash flow classification of the capitalized implementation costs and related amortization expense, and requires additional quantitative and qualitative disclosures. Adoption provides for retrospective or prospective application to all implementation costs incurred after the date of adoption. January 1, 2020 The Company adopted this guidance prospectively on January 1, 2020. As such, adoption had no impact on the Company’s financial statements. Historically, Schwab has expensed implementation costs as they are incurred for CCAs that are service contracts. Therefore, adopting this guidance will change the Company’s accounting treatment for these types of implementation costs going forward. New Accounting Standards Not Yet Adopted Standard Description Required Date of Adoption Effects on the Financial Statements or Other Significant Matters ASU 2020-4, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” Provides optional expedients and exceptions for applying existing accounting guidance to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met, including simplifying accounting analyses for contract modifications. This guidance only applies to the items listed above if they reference LIBOR or another reference rate expected to be discontinued because of reference rate reform and only for a limited period of time. When elected, the optional expedients for contract modifications must be applied consistently for all eligible contracts or eligible transactions subject to the same accounting guidance that would have otherwise been applied. Once elected, the amendments must be applied prospectively. N/A. Effective March 12, 2020 through December 31, 2022 The Company is evaluating the expedients and exceptions provided by this guidance. The elected amendments will be applied prospectively and the Company is currently evaluating the potential impacts on its consolidated financial statements.
