Introduction and Basis of Presentation [Abstract]
Introduction and Basis of Presentation	1. Introduction and Basis of Presentation  CSC is a savings and loan holding company engaged, through its subsidiaries, in wealth management, securities brokerage, banking, asset management, custody, and financial advisory services. Schwab is a securities broker-dealer with over 335 domestic branch offices in 46 states, as well as a branch in each of the Commonwealth of Puerto Rico and London, England. In addition, Schwab serves clients in Hong Kong through one of CSC’s subsidiaries. Other subsidiaries include Schwab Bank, a federal savings bank, and CSIM, the investment advisor for Schwab’s proprietary mutual funds, which are referred to as the Schwab Funds ® , and for Schwab’s exchange-traded funds, which are referred to as the Schwab ETFs™.  The accompanying consolidated financial statements include CSC and its majority-owned subsidiaries (collectively referred to as the Company). Intercompany balances and transactions have been eliminated. These consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the U.S., which require management to make certain estimates and assumptions that affect the reported amounts in the accompanying financial statements. Certain estimates relate to OTTI of investment securities, valuation of goodwill, allowance for loan losses, and legal and regulatory reserves. Actual results may differ from those estimates.  Principles of Consolidation  The Company evaluates for consolidation all entities in which it has financial interests, except for money market funds, which are specifically excluded from consolidation guidance. For an entity subject to consolidation, the Company evaluates whether the Company’s interest in the entity constitutes a controlling financial interest under either the variable interest entity (VIE) model or the voting interest entity (VOE) model. Based upon the Company’s assessments, the Company is not deemed to have a controlling financial interest in and, therefore, is not required to consolidate any VIEs. See Note 10 for further information about VIEs. The Company consolidates all VOEs in which it has majority voting interests.  For investments in entities in which the Company does not have a controlling financial interest, the Company accounts for those investments under the equity method of accounting when the Company has the ability to exercise significant influence over operating and financing decisions of the entity. Investments in entities for which the Company does not have the ability to exercise significant influence are generally carried at cost. Both equity method and cost method investments are included in other assets on the consolidated balance sheets.

Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies  Asset management and administration fees  Asset management and administration fees include mutual fund and ETF service fees and fees for other asset-based financial services provided to individual and institutional clients, and are recognized as revenue over the period that the related service is provided, based upon daily average asset balances. The Company’s policy is to recognize revenue subject to refunds because management can estimate refunds based on Company specific experience. Actual refunds were not material as of December 31, 2016 and for all years presented. The Company earns mutual fund and ETF service fees for shareholder services, administration, and investment management provided to its proprietary funds, and recordkeeping and shareholder services provided to third-party funds. Asset management and administration fees are based upon the daily balances of client assets invested in these funds. The fair values of client assets included in proprietary and third-party mutual funds and ETFs are based on quoted market prices and other observable market data. The Company also earns asset management fees for advice solutions, which include managed portfolios, specialized strategies and customized investment advice. Other asset management and administration fees include various asset-based fees, such as trust fees, 401(k) recordkeeping fees, mutual fund clearing fees, collective trust fund fees, and non-balance based service and transaction fees.  Interest revenue  Interest revenue represents interest earned on cash and cash equivalents, segregated cash and investments, receivables from brokers, dealers, and clearing organizations, receivables from brokerage clients, other securities owned, investment securities, and bank loans. Interest revenue is recognized in the period earned based upon average or daily asset balances and respective interest rates.  Trading revenue  Trading revenue includes commission and principal transaction revenues. Commission revenue is affected by the number of revenue trades executed and the average revenue earned per revenue trade. Principal transaction revenue is primarily comprised of revenue from trading activity in fixed income securities with clients. To accommodate clients’ fixed income trading activity, the Company maintains positions in fixed income securities, including U.S. state and municipal debt obligations, U.S. Government and corporate debt, and other securities. The difference between the price at which the Company buys and sells securities to and from its clients and other broker-dealers is recognized as principal transaction revenue. Principal transaction revenue also includes adjustments to the fair value of these securities positions.  Cash and cash equivalents  The Company considers all highly liquid investments with original maturities of three months or less that are not segregated and on deposit for regulatory purposes to be cash equivalents. Cash and cash equivalents include money market funds, deposits with banks, certificates of deposit, commercial paper, and U.S. Treasury securities. Cash and cash equivalents also include balances that Schwab Bank maintains at the Federal Reserve Bank.  Cash and investments segregated and on deposit for regulatory purposes  Cash and investments segregated and on deposit for regulatory purposes include securities purchased under agreements to resell (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 control of 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. Pursuant to applicable regulations, client cash balances not used for margin lending are segregated into investment accounts maintained for the exclusive benefit of clients by the Company’s broker-dealer subsidiaries.  Receivables from brokerage clients  Receivables from brokerage clients includes 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 doubtful accounts. The Company monitors margin levels and requires clients to deposit additional collateral, or reduce margin positions to meet minimum collateral requirements if the fair value of the collateral changes. Receivables from brokerage clients that remain unsecured or partially secured for more than 30 days are fully reserved for in the allowance for doubtful accounts, except in the case of confirmed fraud, which is reserved immediately. Clients with margin loans have agreed to allow the Company to pledge collateralized securities in accordance with federal regulations. The collateral is not reflected in the consolidated financial statements.  Other securities owned  Other securities owned are recorded at fair value based on quoted market prices or other observable market data. Unrealized gains and losses are included in trading revenue.  Investment Securities  AFS securities are recorded at fair value and unrealized gains and losses are reported, net of taxes, in AOCI included in stockholders’ equity. HTM securities are recorded at amortized cost based on the Company’s positive intent and ability to hold these securities to maturity. Realized gains and losses from sales of AFS securities are determined on a specific identification basis and are included in other revenue.  Management evaluates whether investment securities are OTTI on a quarterly basis. Debt securities with unrealized losses are considered OTTI if the Company intends to sell the security or if it is more likely than not that the Company will be required to sell such security before any anticipated recovery. If management determines that a security is OTTI under these circumstances, the impairment recognized in earnings is measured as the entire difference between amortized cost and fair value.  A security is also OTTI if management does not expect to recover all of the amortized cost of the security. In this circumstance, the impairment recognized in earnings represents the estimated credit loss, and is measured by the difference between the present value of expected cash flows and the amortized cost of the security. Where appropriate, management utilizes cash flow models to estimate the expected future cash flow from the securities to estimate the credit loss. Expected cash flows are discounted using the security’s effective interest rate.  The evaluation of whether the Company expects to recover the amortized cost of a security is inherently judgmental. The evaluation includes the consideration of multiple factors including: the magnitude and duration of the unrealized loss; the financial condition of the issuer; the payment structure of the security; external credit ratings; internal credit ratings; 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 the Company has received all scheduled principal and interest payments.  Securities borrowed and securities loaned  Securities borrowed require the Company to deliver cash to the lender in exchange for securities and are included in receivables from brokers, dealers, and clearing organizations. For securities loaned, the Company receives collateral in the form of cash in an amount equal to or greater than the market value of securities loaned. Securities loaned are included in payables to brokers, dealers, and clearing organizations. The Company monitors the market value of securities borrowed and loaned, with additional collateral obtained or refunded to ensure full collateralization. Fees received or paid are recorded in interest revenue or interest expense.  Bank loans and related allowance for loan 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, loans are recorded net of an allowance for loan losses. The Company’s loan portfolio includes four loan types: First Mortgages, HELOCs, PALs and other loans. Loan segments are defined as the level to which the Company disaggregates its loan types when developing and documenting a methodology for determining the allowance for loan losses.  PALs are collateralized by marketable securities with liquid markets. Credit lines are over-collateralized dependent on the type of security pledged. Collateral market value is monitored on a daily basis and a borrower’s committed line may be reduced or collateral may be liquidated if the collateral is in danger of falling below specified levels. As such, the loss inherent within this portfolio is limited.  The Company records an allowance for loan losses through a charge to earnings based on management’s estimate of probable losses in the existing portfolio. Management reviews the allowance for loan losses quarterly, taking into consideration current economic conditions, the composition of the existing loan portfolio, past loss experience, and risks inherent in the portfolio to ensure that the allowance for loan losses is maintained at an appropriate level .  The methodology to establish an allowance for loan losses utilizes statistical models that estimate prepayments, defaults, and probable losses for the loan segments based on predicted behavior of individual loans within the segments. The methodology considers the effects of borrower behavior and a variety of factors including, but not limited to, interest rates, housing price movements as measured by a housing price index, economic conditions, estimated defaults and foreclosures measured by historical and expected delinquencies, changes in prepayment speeds, LTV ratios, past loss experience, estimates of future loss severities, borrower credit risk, and the adequacy of collateral. The methodology also evaluates concentrations in the loan types, including loan products within those types, year of origination, and geographical distribution of collateral.  Probable 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 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, and interest rates. Delinquency roll rates (i.e., the rates at which loans transition through delinquency stages and ultimately result in a loss) are estimated from the Company’s historical loss experience adjusted for current trends and market information. Loss severity estimates are based on the Company’s historical loss experience and market trends. The estimated loss severity (i.e., loss given default) used in the allowance for loan loss methodology for HELOC loans 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.  This methodology results in loss factors that are applied to the outstanding balances to determine the allowance for loan loss for each loan type.  The Company considers loan modifications in which it makes an economic concession to a borrower experiencing financial difficulty to be troubled debt restructurings (TDR).  Nonaccrual, Nonperforming and Impaired loans  First Mortgages, HELOCs, PALs, and other 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. For the portion of the HELOC portfolio for which the Company is able to track the delinquency status on the associated first lien loan, the Company places a HELOC on non-accrual status if the associated first mortgage is 90 days or more delinquent, regardless of the payment status of the HELOC. When a loan is placed on nonaccrual status, the accrued and unpaid interest receivable is reversed 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. Nonaccrual loans, other real estate owned, and TDRs are considered impaired assets, as it is probable the Company will not collect all amounts due.  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 loan losses and the loan balance. The Company’s 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 or not 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.  Equipment, office facilities, and property  Equipment, office facilities, and property are recorded at cost net of accumulated depreciation and amortization, except for land, which is recorded at cost. Equipment and office facilities are depreciated on a straight-line basis over an estimated useful life of five to ten years. Buildings are depreciated on a straight-line basis over 20 to 40 years. Leasehold improvements are amortized on a straight-line basis over the shorter of the estimated useful life of the asset or the term of the lease. Software and certain costs incurred for purchasing or developing software for internal use are amortized on a straight-line basis over an estimated useful life of three or five years. Equipment, office facilities, and property are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable.  Goodwill  Goodwill represents the fair value of acquired businesses in excess of the fair value of the individually identified net assets acquired. Goodwill is not amortized but is tested for impairment annually or whenever indications of impairment exist. The Company’s annual impairment testing date is April 1 st . The Company can elect to qualitatively assess goodwill for impairment if it is more likely than not that the fair value of a reporting unit exceeds its carrying value.  If the Company elects to bypass qualitatively assessing goodwill, or it is not more likely than not that the fair value of a reporting unit exceeds its carrying value, management estimates the fair values of each of the Company’s reporting units (defined as the Company’s businesses for which financial information is available and reviewed regularly by management) and compares it to their carrying values. Based on the Company’s analysis, fair value significantly exceeded the carrying value for all reporting units as of its annual testing date.  Intangible assets  Intangible assets are amortized over their useful lives in a manner that best reflects their economic benefit. Intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. The Company does not have any indefinite-lived intangible assets.  Low-Income Housing Tax Credit (LIHTC) Investments  As part of the Company’s community reinvestment initiatives, the Company invests with other institutional investors in funds that make equity investments in multifamily affordable housing properties. The Company receives tax credits and other tax benefits for these investments. The Company accounts for investments in qualified affordable housing projects using the proportional amortization method if certain criteria are met. The proportional amortization method amortizes the cost of the investment over the period in which the investor expects to receive tax credits and other tax benefits, and the resulting amortization is recognized as a component of income tax expense attributable to continuing operations. The carrying value of LIHTC investments is included in other assets on the consolidated balance sheets. Unfunded commitments related to LIHTC investments are included in accrued expenses and other liabilities on the consolidated balance sheets.  Guarantees and indemnifications  The Company recognizes, at the inception of a guarantee, a liability equal to the estimated fair value of the obligation undertaken in issuing the guarantee. The fair values of obligations relating to guarantees are estimated based on transactions for similar guarantees or expected present value measures.  Advertising and market development  Advertising and market development activities include the cost to produce and distribute marketing campaigns as well as client incentives and discounts. Such costs are generally expensed when incurred.  Income taxes  The Company provides for income taxes on all transactions that have been recognized in the consolidated financial statements. Accordingly, deferred tax assets are adjusted to reflect the tax rates at which future taxable amounts will likely be settled or realized. The effects of tax rate changes on future deferred tax assets and deferred tax liabilities, as well as other changes in income tax laws, are recorded in earnings in the period during which such changes are enacted. The Company’s unrecognized tax benefits, which are included in accrued expenses and other liabilities, represent the difference between positions taken on tax return filings and estimated potential tax settlement outcomes. Accrued interest relating to unrecognized tax benefits is recorded in income tax expense and penalties are recorded in other expense.  Share-based compensation  Share-based compensation includes employee and board of director stock options and restricted stock units. The Company measures compensation expense for these share-based payment arrangements based on their estimated fair values as of the unit’s grant date. The fair value of the share-based award is recognized over the vesting period as share-based compensation. Share-based compensation expense is based on units expected to vest and therefore is reduced for estimated forfeitures. Forfeitures are estimated at the time of grant based on the Company’s historical forfeiture experience and revised in subsequent periods if actual forfeitures differ from those estimates. The excess tax benefits from the exercise of stock options and the vesting of restricted stock units are recorded in additional paid-in capital.  Fair values of assets and liabilities  Fair value is defined as the price that would be received to sell an asset or the price paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurement accounting guidance describes the fair value hierarchy for disclosing assets and liabilities measured at fair value based on the inputs used to value them. The fair value hierarchy maximizes the use of observable inputs and minimizes the use of unobservable inputs. Observable inputs are based on market pricing data obtained from sources independent of the Company. A quoted price in an active market provides the most reliable evidence of fair value and is generally used to measure fair value whenever available.  Unobservable inputs reflect management’s judgment about the assumptions market participants would use in pricing the asset or liability. Where inputs used to measure fair value of an asset or liability are from different levels of the hierarchy, the asset or liability is categorized based on the lowest level input that is significant to the fair value measurement in its entirety. Assessing the significance of a particular input requires judgment. The fair value hierarchy includes three levels based on the objectivity of the inputs as follows:  · Level 1 inputs are quoted prices in active markets as of the measurement date for identical assets or liabilities that the Company has the ability to access.  · Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets and liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates, benchmark yields, issuer spreads, new issue data, and collateral performance.  · Level 3 inputs are unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability.  The Company’s policy is to recognize transfers of financial instruments between levels as of the beginning of the reporting period in which a transfer occurs.  Assets and liabilities measured at fair value on a recurring basis  The Company’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, other securities owned, and AFS securities. 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. 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 do not exist, the Company uses prices obtained from independent third-party pricing services to measure the fair value of investment assets. The Company generally obtains prices from at least three independent pricing sources for assets recorded at fair value.  The Company’s primary independent pricing service provides prices based on observable trades 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. The Company compares the prices obtained from its 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. The Company 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 a material difference in the recorded amounts.  Fair value of other financial instruments  Descriptions of the valuation methodologies and assumptions used to estimate the fair value of other financial instruments are described below. The Company’s financial instruments not recorded at fair value but for which fair value can be approximated and disclosed include:  · Cash and cash equivalents are short-term in nature and accordingly are recorded at amounts that approximate fair value.  · Cash and investments segregated and on deposit for regulatory purposes include cash and securities purchased under resale agreements. Securities purchased under resale agreements are short-term in nature and are backed by collateral that both exceeds the carrying value of the resale agreement and is highly liquid in nature. Accordingly, the carrying values of these financial instruments approximate their fair values.  · Receivables from/payables to brokers, dealers, and clearing organizations are short-term in nature, recorded at contractual amounts and historically have been settled at those values. Accordingly, the carrying values of these financial instruments approximate their fair values.  · Receivables from/payables to brokerage clients — net are short-term in nature, recorded at contractual amounts and historically have been settled at those values. Accordingly, the carrying values of these financial instruments approximate their fair values.  · HTM securities – The fair values of HTM securities are obtained using an independent third-party pricing service similar to investment assets recorded at fair value as discussed above.  · Bank loans – The fair values of the Company’s First Mortgages and HELOCs are estimated based on prices of mortgage-backed securities collateralized by similar types of loans. PALs are non-purpose revolving lines of credit secured by eligible assets; accordingly, the carrying values of these loans approximate their fair values.  · Financial instruments included in other assets primarily consist of LIHTC investments, cost method investments and FHLB stock, whose carrying values approximate their fair values. FHLB stock is recorded at par, which approximates its fair value.  · Bank deposits have no stated maturity and are recorded at the amount payable on demand as of the balance sheet date. The Company considers the carrying values of these deposits to approximate their fair values.  · Financial instruments included in accrued expenses and other liabilities consist of drafts payable and certain amounts due under contractual obligations, including unfunded LIHTC commitments. The carrying values of these instruments approximate their fair values.  · Short-term borrowings consist of commercial paper and funds drawn on Schwab Bank’s secured credit facility with the Federal Home Loan Bank of San Francisco. Due to the short-term nature of these borrowings, carrying value approximates fair value.  · Long-term debt – Except for the finance lease obligation, the fair values of long-term debt are estimated using indicative, non-binding quotes from independent brokers. The Company validates indicative prices for its debt through comparison to other independent non-binding quotes. The finance lease obligation is recorded at carrying value, which approximates fair value.  · Firm commitments to extend credit – The Company extends credit to banking clients through HELOCs and PALs. The Company considers the fair value of these unused commitments to not be material because the interest rates earned on these balances are based on floating interest rates that reset monthly.  New Accounting Standards  Adoption of New Accounting Standards  On January 1, 2016, the Company adopted ASU 2015-02, “Consolidation (Topic 810),” which amends the analysis a reporting entity must perform to determine whether it should consolidate certain types of legal entities. The new guidance is applicable to all entities but provides an exception for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. The adoption of ASU 2015-02 did not have an impact on the Company’s consolidated financial statements or EPS, as the new guidance did not change any consolidation conclusions reached in accordance with the previous guidance.  On January 1, 2016, the Company adopted ASU 2015-03, “Interest – Imputation of Interest (Subtopic 835-30).” ASU 2015-03 requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. Previously, debt issuance costs were presented as a separate asset on the balance sheet. The guidance in ASU 2015-03 has been applied on a retrospective basis, which requires the adjustment of all prior period consolidated balance sheets. The effect of the adoption on the Company’s December 31, 2015 consolidated balance sheet was to decrease other assets and total assets by $13 million and to decrease long-term debt and total liabilities by $13 million. The Company considers the reclassifications immaterial.  On January 1, 2016, the Company also adopted ASU 2015-05, “Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40),” which provides new guidance that clarifies customers’ accounting for fees paid in a cloud computing arrangement. Under the new guidance, if a cloud computing arrangement includes a software license, the customer shall account for the software license element of the arrangement consistent with the acquisition of other software licenses. If the cloud computing arrangement does not include a software license, the customer shall account for the arrangement as a service contract. The guidance applies to all new arrangements entered into after January 1, 2016. The adoption of ASU 2015-05 did not have an impact on the Company’s financial statements or EPS.  New Accounting Standards Not Yet Adopted  In May 2014, the Financial Accounting Standards Board (FASB) issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” which provides new guidance on revenue recognition. The guidance clarifies that revenue from contracts with customers should be recognized in a manner that depicts the timing of the related transfer of goods or performance of services at an amount that reflects the expected consideration. The FASB has subsequently issued several amendments to the standard, including deferral of the effective date until January 1, 2018, clarification of principal versus agent considerations, narrow scope improvements and other technical corrections. Entities may elect either full or modified retrospective transition. Full retrospective transition will require a cumulative effect adjustment to retained earnings as of the earliest comparative period presented. Modified retrospective transition will require a cumulative effect adjustment to retained earnings as of the beginning of the reporting period in which the entity first applies the new guidance.  The Company plans to adopt the revenue recognition guidance in the first quarter of 2018. The guidance does not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other U.S. GAAP. Accordingly, the Company does not expect an impact to net interest revenue. While the Company has not yet identified any changes in the timing of revenue recognition, the Company’s review is ongoing. The Company is evaluating the impact the new standard will have on the presentation of certain revenue streams (gross versus net reporting) and the capitalization of contract costs. The Company has not yet selected a transition method and continues to evaluate the impact the new guidance will have on its financial statements and EPS.  In January 2016, the FASB issued ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10),” which will become effective January 1, 2018. This new guidance addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The main provisions of the guidance include (i) most equity investments are to be measured at fair value with changes in fair value recognized in net income, except

Nonperforming assets, which include nonaccrual loans and other real estate owned, totaled $31 million and $36 million at December 31, 2016 and 2015 , respectively. Impaired assets, which include nonaccrual loans, other real estate owned and TDRs, totaled $45 million and $50 million at December 31, 2016 and 2015, respectively. TDRs were not material at December 31, 2016 or 2015 .  In addition to monitoring delinquency, the Company 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 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 were last updated in December 2016. 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 estimated by reference to a home price appreciation index.  As of December 31, 2016 and 2015, 48 % of the Company’s HELOC and First Mortgage portfolio was concentrated in California. These loans have performed in a manner consistent with the portfolio as a whole.  The credit quality indicators of the Company’s bank loan portfolio are detailed below:    Weighted Percent of Loans  Average Utilization that are on  December 31, 2016 Balance Updated FICO Rate (1) Nonaccrual Status  Residential real estate mortgages:  Estimated Current LTV  < 70% $ 8,350 774 N/A 0.04 %  >70% – < 90% 743 768 N/A 0.35 %  >90% – < 100% 21 747 N/A 2.08 %  >100% 20 709 N/A 14.50 %  Total $ 9,134 773 N/A 0.10 %  Home equity loans and lines of credit:  Estimated Current LTV (2)  < 70% $ 2,070 771 35 % 0.12 %  >70% – < 90% 234 757 50 % 0.40 %  >90% – < 100% 29 747 66 % 1.74 %  >100% 17 728 70 % 3.73 %  Total $ 2,350 769 36 % 0.20 %  Pledged asset lines:  Weighted Average LTV (2)  =70% $ 3,851 763 46 % -  (1) The Utilization Rate is calculated using the outstanding balance divided by the associated total line of credit.

Variable Interest Entities [Abstract]
Variable Interest Entities	 10. Variable Interest Entities  A VIE requires consolidation by the entity’s primary beneficiary. The Company evaluates all entities in which it has a financial interest to determine if the entity is a VIE and if so, whether the Company is the primary beneficiary. See “ Principles of Consolidation ” in Note 1 for discussion of the Company’s evaluations of VIEs and whether it is deemed to be the primary beneficiary of any VIEs in which it holds an interest. The Company was not the primary beneficiary of, and therefore, not required to consolidate any VIEs during 2016, 2015, or 2014.  Community Reinvestment Act investments  Schwab Bank is subject to the CRA. The CRA is intended to encourage banks to help meet the credit needs of the communities in which they operate, including low and moderate income neighborhoods, consistent with safe and sound banking operations. As part of Schwab Bank’s community reinvestment initiatives, Schwab Bank invests with other institutional investors in funds that make equity investments in multifamily affordable housing properties. Schwab Bank receives tax credits and other tax benefits for these investments. Schwab Bank’s LIHTC investments are accounted for using the proportional amortization method. See Note 2 for discussion of the application of the proportional amortization method. Amortization, tax credits, and other tax benefits recognized in relation to LIHTC investments are included in taxes on income on the consolidated statements of income. As of December 31, 2016 and 2015, the majority of the Company’s VIEs related to Schwab Bank’s LIHTC investments.  The carrying value of the LIHTC investments was $189 million and $104 million as of December 31, 2016 and 2015, respectively, which is included in other assets on the consolidated balance sheets. Schwab Bank recorded liabilities of $135 million and $84 million for unfunded commitments related to LIHTC investments at December 31, 2016 and 2015, respectively, which are included in accrued expenses and other liabilities on the consolidated balance sheets. Schwab Bank’s funding of these remaining commitments is dependent upon the occurrence of certain conditions and Schwab Bank expects to pay substantially all of these commitments between 2017 and 2020 .  Aggregate assets, liabilities and maximum exposure to loss  The aggregate assets, liabilities, and maximum exposure to loss from those VIEs in which the Company holds a variable interest, but as to which the Company has concluded it is not the primary beneficiary, are summarized in the table below:    December 31, 2016 December 31, 2015  Maximum Maximum  Aggregate Aggregate exposure Aggregate Aggregate exposure  assets liabilities to loss assets liabilities to loss  LIHTC Investments $ 189 $ 135 $ 189 $ 104 $ 84 $ 104  Other CRA Investments (1) 60 - 80 57 - 66  Total $ 249 $ 135 $ 269 $ 161 $ 84 $ 170   (1) Other CRA investments are recorded using either the cost method or the equity method. Aggregate assets are included in either other assets or bank loans – net on the consolidated balance sheets.  The Company’s maximum exposure to loss would result from the loss of the investments, including any committed amounts. During the years ended December 31, 2016 and 2015, the Company did not provide or intend to provide financial or other support to the VIEs that it was not contractually required to provide.

CSC has a Shelf Registration Statement on file with the SEC, which enables CSC to issue debt, equity, and other securities.  The Senior Notes outstanding at December 31, 2016 , have maturities ranging from 2018 to 2026 and bear interest at a weighted-average rate of 3.03% with interest payable semi-annually.  On November 13, 2015, CSC issued $350 million aggregate principal amount of Senior Notes that mature in 2026 . The Senior Notes have a fixed interest rate of 3.450% with interest payable semi-annually.  On March 10, 2015, CSC issued $625 million aggregate principal amount of Senior Notes that mature in 2018 and $375 million aggregate principal amount of Senior Notes that mature in 2025 . The Senior Notes due 2018 and 2025 have a fixed interest rate of 1.50% and 3.00% , respectively, with interest payable semi-annually.  The Medium-Term Notes, Series A (Medium-Term Notes) outstanding at December 31, 2016 , mature in 2017 and have a fixed interest rate of 6.375% with interest payable semi-annually.  Schwab has a finance lease obligation related to an office building and land under a 20 -year lease. The remaining finance lease obligation of $68 million at December 31, 2016 , is being reduced by a portion of the lease payments over the remaining lease term of eight years.  Annual maturities on long-term debt outstanding at December 31, 2016 , are as follows:    2017 $ 258  2018 908  2019 8  2020 709  2021 9  Thereafter 1,008  Total maturities 2,900  Unamortized discount, net (14)  Debt issuance costs (10)  Total long-term debt $ 2,876  Short-term borrowings: Schwab Bank maintains a secured credit facility with the FHLB. Amounts available under this facility are dependent on the amount of Schwab Bank’s First Mortgages, HELOCs, and the fair value of certain of Schwab Bank’s investment securities that are pledged as collateral. During 2016, Schwab Bank used borrowings under this agreement to purchase investment securities prior to bulk transfers. No amounts were outstanding under this facility as of December 31, 2016 or 2015. As a condition of the borrowings, Schwab Bank purchased $152 million of FHLB stock, recorded at par, and sold $88 million of FHLB stock in 2016, with the net investment recorded in other assets on the consolidated balance sheets. Schwab Bank sold $8 million of FHLB stock during 2015.  CSC has authorization from its Board of Directors to issue Commercial Paper Notes not to exceed $1.5 billion. Management has set a current limit for the commercial paper program not to exceed the amount of the committed, unsecured credit facility, which was $750 million at December 31, 2016. The maturities of the Commercial Paper Notes may vary, but are not to exceed 270 days from the date of issue. The commercial paper is not redeemable prior to maturity and cannot be voluntarily prepaid. The proceeds of the commercial paper program are to be used for general corporate purposes. CSC had no borrowings of Commercial Paper Notes outstanding at December 31, 2016 or 2015 .  CSC maintains a $750 million committed, unsecured credit facility with a group of banks, which is scheduled to expire in June 2017 . This facility replaced a similar facility that expired in June 2016. The funds under this facility are available for general corporate purposes. The financial covenants require Schwab to maintain a minimum net capital ratio, as defined, Schwab Bank to be well capitalized, as defined, and CSC to maintain a minimum level of stockholders’ equity, adjusted to exclude AOCI. At December 31, 2016 , the minimum level of stockholders’ equity required under this facility was $10.2 billion (CSC’s stockholders’ equity, excluding AOCI, at December 31, 2016 , was $16.6 billion). There were no borrowings outstanding under these facilities at December 31, 2016 or 2015 .  To manage short-term liquidity, Schwab maintains uncommitted, unsecured bank credit lines with several banks. There were no borrowings outstanding under these lines at December 31, 2016 or 2015 .

Commitments and Contingencies [Abstract]
Commitments and Contingencies	14. Commitments and Contingencies  Operating leases: The Company has non-cancelable operating leases for office space and equipment. Future annual minimum rental commitments under these leases, net of contractual subleases are as follows:    Operating  December 31, 2016 Leases Subleases Net  2017 $ 137 $ 29 $ 108  2018 109 8 101  2019 84 4 80  2020 73 4 69  2021 64 5 59  Thereafter 318 2 316  Total $ 785 $ 52 $ 733  Certain leases contain provisions for renewal options, purchase options, and rent escalations based on increases in certain costs incurred by the lessor. Rent expense relating to operating leases was $123 million, $116 million, and $114 million in 2016, 2015, and 2014, respectively.  Purchase obligations: The Company has purchase obligations for services such as advertising and marketing, telecommunications, professional services, and hardware- and software-related agreements. The Company has purchase obligations as follows:    December 31, 2016  2017 $ 211  2018 88  2019 44  2020 21  2021 20  Thereafter 200  Total $ 584  Guarantees and indemnifications: The Company 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. The Company partially satisfies the margin requirements by arranging unsecured standby LOCs, in favor of the Options Clearing Corporation, which are issued by several banks. At December 31, 2016 , the aggregate face amount of these LOCs totaled $295 million. There were no funds drawn under any of these LOCs at December 31, 2016 . In connection with its securities lending activities, the Company 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 cash and securities it has posted as collateral. The potential requirement for the Company to make payments under these arrangements is remote. Accordingly, no liability has been recognized for these guarantees.  Legal contingencies: The Company 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.  The Company 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 certain 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. 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; potential opportunities for settlement and the status of any settlement discussions; and potential insurance coverage and indemnification. It may not be possible to reasonably estimate potential liability, if any, or 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.  Total Bond Market Fund Litigation : On August 28, 2008, a class action lawsuit was filed in the U.S. District Court for the Northern District of California on behalf of investors in the Schwab Total Bond Market Fund™. The lawsuit, which alleged violations of state law and federal securities law in connection with the fund’s investment policy, named CSIM, Schwab Investments (registrant and issuer of the fund’s shares) and certain current and former fund trustees as defendants. Allegations include that the fund improperly deviated from its stated investment objectives by investing in collateralized mortgage obligations (CMOs) and investing more than 25% of fund assets in CMOs and mortgage-backed securities without obtaining a shareholder vote. Plaintiff seeks unspecified compensatory and rescission damages, unspecified equitable and injunctive relief, costs and attorneys’ fees. Plaintiff’s federal securities law claim and certain of plaintiff’s state law claims were dismissed. On August 8, 2011, the court dismissed plaintiff’s remaining claims with prejudice. Plaintiff appealed to the Ninth Circuit, which issued a ruling on March 9, 2015 reversing the district court’s dismissal of the case and remanding the case for further proceedings. Plaintiff filed a fourth amended complaint on June 25, 2015, and in decisions issued October 6, 2015 and February 23, 2016, the court dismissed all claims with prejudice. Plaintiff has appealed to the Ninth Circuit, where the case is again pending.  Other Matters : On April 16, 2012, optionsXpress was charged by the SEC in an administrative proceeding alleging violations of its close-out obligations under Regulation SHO (short sale delivery rules) in connection with certain customer trading activity. Following trial, in a decision issued June 7, 2013, the judge held that optionsXpress had violated Regulation SHO and aided and abetted fraudulent trading activity by its customer, and ordered optionsXpress and the customer to pay disgorgement and penalties in an amount that would not be material. The Company appealed to the SEC, and in a decision issued August 18, 2016 and amended September 13, 2016, the SEC dismissed all fraud charges but affirmed the violations of Regulation SHO and the financial sanctions imposed by its administrative law judge. This matter is now concluded.

Financial Instruments Subject to Off-Balance Sheet Credit Risk or Concentration Risk [Abstract]
Financial Instruments Subject to Off-Balance Sheet Credit Risk or Concentration Risk	  15. Financia l Inst ruments Subject to Off-Balance Sheet Credit Risk or Concentration Risk  Off-Balance Sheet Credit Risk  Resale and repurchase 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. Schwab utilizes the collateral provided under these resale agreements to meet obligations under broker-dealer client protection rules, which place limitations on its ability to access such segregated securities. For Schwab to repledge or sell this collateral, it would be required to deposit cash and/or securities of an equal amount into its segregated reserve bank accounts in order to meet its segregated cash and investment requirement. The Company’s resale agreements are not subject to master netting arrangements.  Securities lending: The Company loans brokerage client securities temporarily to other brokers 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, the Company may be exposed to the risk of acquiring the securities at prevailing market prices in order to satisfy its client obligations. The Company mitigates this risk by requiring credit approvals for counterparties, monitoring the fair value of securities loaned, and requiring additional cash as collateral when necessary. The Company borrows securities from other broker-dealers to fulfill short sales by brokerage clients and delivers cash to the lender in exchange for the securities. The fair value of these borrowed securities was $213 million and $72 million at December 31, 2016 and 2015 , respectively. All of the Company’s securities lending transactions are subject to enforceable master netting arrangements with other broker-dealers; however, the Company does not net securities lending transactions. Therefore, the Company’s securities loaned and securities borrowed are presented gross in the consolidated balance sheets.  The following table presents information about the Company’s resale agreements and securities lending activity to enable the users of the Company’s financial statements to evaluate the potential effect of rights of setoff between these recognized assets and recognized liabilities at December 31, 2016 and 2015.    Gross Amounts Not Offset in the  Gross Amounts Net Amounts Consolidated Balance Sheets  Gross Offset in the Presented in the  Assets/ Consolidated Consolidated Counterparty Net  Liabilities Balance Sheets Balance Sheets Offsetting Collateral Amount  December 31, 2016  Assets:  Resale agreements (1) $ 9,547 $ - $ 9,547 $ - $ (9,547) (2) $ -  Securities borrowed (3) 393 - 393 (200) (189) 4  Total $ 9,940 $ - $ 9,940 $ (200) $ (9,736) $ 4  Liabilities:  Securities loaned (4,5) $ 1,996 $ - $ 1,996 $ (200) $ (1,660) $ 136  Total $ 1,996 $ - $ 1,996 $ (200) $ (1,660) $ 136   December 31, 2015  Assets:  Resale agreements (1) $ 8,088 $ - $ 8,088 $ - $ (8,088) (2) $ -  Securities borrowed (3) 198 - 198 (70) (127) 1  Total $ 8,286 $ - $ 8,286 $ (70) $ (8,215) $ 1  Liabilities:  Securities loaned (4,5) $ 2,233 $ - $ 2,233 $ (70) $ (1,990) $ 173  Total $ 2,233 $ - $ 2,233 $ (70) $ (1,990) $ 173  (1) Included in cash and investments segregated and on deposit for regulatory purposes in the Company’s consolidated balance sheets. (2) Actual collateral was greater than or equal to 102% of the related assets. At December 31, 2016 and 2015, the fair value of collateral received in connection with resale agreements that are available to be repledged or sold was $9.8 billion and $8.2 billion, respectively. (3) Included in receivables from brokers, dealers, and clearing organizations in the Company’s consolidated balance sheets. (4) Included in payables to brokers, dealers, and clearing organizations in the Company’s consolidated balance sheets. (5) Securities loaned are predominantly comprised of equity securities held in client brokerage accounts with overnight and continuous remaining contractual maturities.  Client trade settlement: The Company is obligated to settle transactions with brokers and other financial institutions even if the Company’s clients fail to meet their obligations to the Company. Clients are required to complete their transactions on settlement date, generally three business days after the trade date. If clients do not fulfill their contractual obligations, the Company may incur losses. The Company has established procedures to reduce this risk by requiring deposits from clients in excess of amounts prescribed by regulatory requirements for certain types of trades, and therefore the potential to make payments under these client transactions is remote. Accordingly, no liability has been recognized for these transactions .  Margin lending: Clients with margin loans have agreed to allow the Company to pledge collateralized securities in their brokerage accounts in accordance with federal regulations. The following table summarizes the fair value of client securities available, under such regulations, for the Company to utilize as collateral, and the amounts pledged by the Company.    December 31, 2016 2015  Fair value of client securities available to be pledged $ 21,516 $ 22,385  Fair value of client securities pledged for:  Securities lending to other broker-dealers 1,626 1,935  Fulfillment of client short sales 2,048 1,344  Fulfillment of requirements with the Options Clearing Corporation (1) 1,519 1,450  Total collateral pledged $ 5,193 $ 4,729  Note: Excludes amounts available and pledged for securities lending from fully-paid client securities. The fair value of fully-paid client securities available and pledged was $58 million as of December 31, 2016 and $43 million as of December 31, 2015. (1) Client securities pledged to fulfill client margin requirements for open option contracts established with the Options Clearing Corporation.  Financial Guarantees: See Note 14 for additional information.  Concentration Risk  The Company has exposure to concentration risk when holding large positions of financial instruments collateralized by assets with similar economic characteristics or in securities of a single issuer or industry.  The fair value of the Company’s investments in mortgage-backed securities totaled $105.9 billion at December 31, 2016 . Of these, $104.9 billion were issued by U.S. agencies and $1.0 billion were issued by private entities (non-agency securities). The fair value of the Company’s investments in mortgage-backed securities totaled $72.3 billion at December 31, 2015. Of these, $71.0 billion were issued by U.S. agencies and $1.3 billion were non-agency securities. These U.S. agency and non-agency securities are included in investment securities in the consolidated balance sheets.  The fair value of the Company’s investments in corporate debt securities and commercial paper totaled $10.6 billion and $11.1 billion at December 31, 2016 and 2015 , respectively . At December 31, 2016, approximately 48% of these investments were issued by institutions in the financial services industry. These securities are include d in investment securities, cash and cash equivalents, and other securities owned.  The Company’s bank loans include $8.2 billion and $7.5 billion of adjustable rate First Mortgages at December 31, 2016 and 2015 , respectively. At December 31, 2016 , approximately 36% of these mortgages consisted of loans with interest-only payment terms. At December 31, 2016 , the interest rates on approximately 58% of these interest-only loans are not scheduled to reset for three or more years. For additional detail on concentrations in bank loans, see Note 6.  Fees received from Schwab’s proprietary mutual funds and ETFs represented 13% , 8% , and 7% of the Company’s net revenues in 2016, 2015, and 2014, respectively. Except for Schwab’s proprietary mutual funds and ETFs, which are considered a single client for purposes of this computation, no single client accounted for more than 10% of the Company’s net revenues in 2016, 2015, or 2014. Substantially all of the Company’s revenues and assets are generated or located in the U.S. The percentage of Schwab’s total client accounts located in California was 23% at December 31, 2016, 2015, and 2014.  The Company also has exposure to concentration risk from its margin and securities lending activities collateralized by securities of a single issuer or industry. This concentration risk is mitigated by collateral arrangements that require the fair value of such collateral exceeds the amounts loaned, as described above.

Options generally vest annually over a three - to five -year period from the date of grant.  The Company’s stock option activity is summarized below:    Weighted-  Weighted- Average  Number Average Remaining Aggregate  of Options Exercise Price Contractual Intrinsic  (In millions) per Share Life (in years) Value  Outstanding at December 31, 2015 40 $ 19.82  Granted 6 30.05  Exercised (9) 16.77  Forfeited - 26.59  Expired - 22.57  Outstanding at December 31, 2016 37 $ 22.12 6.50 $ 649  Vested and expected to vest at December 31, 2016 37 $ 22.03 6.47 $ 646  Vested and exercisable at December 31, 2016 23 $ 17.94 5.21 $ 505  The aggregate intrinsic value in the table above represents the difference between CSC’s closing stock price and the exercise price of each in-the-money option on the last trading day of the period presented.  Information on stock options granted and exercised is presented below:    Year Ended December 31, 2016 2015 2014  Weighted-average fair value of options granted per share $ 8.73 $ 8.56 $ 7.82  Cash received from options exercised 144 90 189  Tax benefit realized on options exercised 38 22 8  Aggregate intrinsic value of options exercised 149 90 86  Management uses an option pricing model to estimate the fair value of options granted. The model takes into account the contractual term of the stock option, expected volatility, dividend yield, and risk-free interest rate. Expected volatility is based on the implied volatility of publicly-traded options on CSC’s stock. Dividend yield is based on the average historical CSC dividend yield. The risk-free interest rate is based on the yield of a U.S. Treasury zero-coupon issue with a remaining term similar to the contractual term of the option. Management uses historical option exercise data, which includes employee termination data, to estimate the probability of future option exercises. Management uses the Black-Scholes model to solve for the expected life of options. The assumptions used to value the Company’s options granted during the years presented and their expected lives were as follows:    Year Ended December 31, 2016 2015 2014  Weighted-average expected dividend yield 1.22 % 1.22 % 1.20 %  Weighted-average expected volatility 30 % 28 % 28 %  Weighted-average risk-free interest rate 1.8 % 2.2 % 2.4 %  Expected life (in years) 4.7 - 7.3 4.7 - 7.5 4.4 - 7.2  Restricted Stock Units  Restricted stock units are awards that entitle the holder to receive shares of CSC’s common stock following a vesting period. Restricted stock units are restricted from transfer or sale and generally vest annually over a three - to five -year period, while performance-based restricted stock units also require the Company achieve certain financial or other measures prior to vesting. The fair value of restricted stock units is based on the market price of the Company’s stock on the date of grant. The grant date fair value is amortized to compensation expense on a straight-line basis over the requisite service period. The fair value of the restricted stock units that vested during each of the years 2016, 2015, and 2014 was $105 million, $126 million, and $116 million, respectively.  The Company’s restricted stock units activity is summarized below:    Weighted-  Number Average Grant  of Units Date Fair Value  (In millions) per Unit  Outstanding at December 31, 2015 8 $ 25.84  Granted 3 30.64  Vested (3) 22.53  Forfeited - 25.80  Outstanding at December 31, 2016 8 $ 29.41  Retirement Plan  Employees of the Company can participate in the Company’s qualified retirement plan, the SchwabPlan ® Retirement Savings and Investment Plan. The Company may match certain employee contributions or make additional contributions to this plan at its discretion. The Company’s total expense was $83 million, $78 million, and $68 million in 2016, 2015, and 2014, respectively.  Deferred Compensation Plans  The Company’s deferred compensation plan for officers permits participants to defer the receipt of certain cash compensation. The Company’s deferred compensation plan for non-employee directors permits participants to defer receipt of all or a portion of their director fees and to receive either a grant of stock options, or upon ceasing to serve as a director, the number of shares of CSC’s common stock that would have resulted from investing the deferred fee amount into CSC’s common stock. The deferred compensation liability was $135 million and $129 million at December 31, 2016 and 2015 , respectively.  FC Career Achievement Plan The Company’s FC career achievement plan was implemented in January 2014 and is a noncontributory, unfunded, nonqualified plan for eligible FCs. An FC is eligible for earned cash payments after retirement contingent upon meeting certain performance levels, tenure, age and client transitioning requirements. Allocations to the plan are completed annually by the Company and are subject to general creditors of the Company. Based on the performance level achieved, an FC will receive an award calculated as a percentage of eligible compensation. Full vesting occurs when an FC reaches 60 years of age and has at least ten years of service with the Company. The Company is using the Society of Actuaries MP-2016 mortality improvement scale for its mortality assumptions.

Earnings Per Common Share [Abstract]
Earnings Per Common Share	21. Earnings Per Common Share  EPS is computed using the two-class method. Preferred stock dividends, and undistributed earnings and dividends allocated to participating securities are subtracted from net income in determining net income available to common stockholders. Basic EPS is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding during the period. The computation of diluted EPS is similar to the computation of basic EPS except that the denominator is increased to include the number of additional common shares that would have been outstanding if dilutive potential common shares had been issued. Dilutive potential common shares include, if dilutive, the effect of outstanding stock options and non-vested restricted stock units. EPS under the basic and diluted computations is as follows:    Year Ended December 31, 2016 2015 2014  Net income $ 1,889 $ 1,447 $ 1,321  Preferred stock dividends and other (1) (143) (83) (60)  Net income available to common stockholders $ 1,746 $ 1,364 $ 1,261  Weighted-average common shares outstanding — basic 1,324 1,315 1,303  Common stock equivalent shares related to stock incentive plans 10 12 12  Weighted-average common shares outstanding — diluted (2) 1,334 1,327 1,315  Basic EPS $ 1.32 $ 1.04 $ .96  Diluted EPS $ 1.31 $ 1.03 $ .95   (1) Includes preferred stock dividends and undistributed earnings and dividends allocated to non-vested restricted stock units.

Regulatory Requirements [Abstract]
Regulatory Requirements	22. Regulatory Requirements  CSC is a savings and loan holding company and Schwab Bank, CSC’s depository institution subsidiary, is a federal savings bank. CSC is subject to examination, supervision, and regulation by the Federal Reserve. Schwab Bank is subject to examination, supervision, and regulation by the OCC, as its primary regulator, the FDIC as its deposit insurer, and the CFPB. CSC is required to serve as a source of strength for Schwab Bank.  Schwab Bank is subject to various requirements and restrictions under federal and state laws, including regulatory capital requirements and requirements that restrict and govern the terms of affiliate transactions, such as extensions of credit to, or asset purchases from CSC or its other subsidiaries by Schwab Bank. In addition, Schwab Bank is required to provide notice to and may be required to obtain approval of the OCC and the Federal Reserve to declare dividends to CSC. The federal banking agencies have broad powers to enforce these regulations, including the power to terminate deposit insurance, impose substantial fines and other civil and criminal penalties, and appoint a conservator or receiver. Under the Federal Deposit Insurance Act, Schwab Bank could be subject to restrictive actions if it were to fall within one of the lowest three of five capital categories. CSC and Schwab Bank are required to maintain minimum capital levels as specified in federal banking regulations. Failure to meet the minimum levels could result in certain mandatory, and possibly additional discretionary actions by the regulators that, if undertaken, could have a direct material effect on CSC and Schwab Bank. At December 31, 2016 , both CSC and Schwab Bank met all of their respective capital requirements. Certain events, such as growth in bank deposits and regulatory discretion, could adversely affect CSC’s or Schwab Bank’s ability to meet future capital requirements.  The regulatory capital and ratios for CSC and Schwab Bank are as follows:    Minimum to be Minimum Capital  Actual Well Capitalized Requirement  December 31, 2016 Amount Ratio Amount Ratio Amount Ratio  CSC  Common Equity Tier 1 Risk-Based Capital $ 12,574 18.4 % N/A $ 3,068 4.5 %  Tier 1 Risk-Based Capital 15,357 22.5 % N/A 4,091 6.0 %  Total Risk-Based Capital 15,384 22.6 % N/A 5,454 8.0 %  Tier 1 Leverage 15,357 7.2 % N/A 8,516 4.0 %  Schwab Bank  Common Equity Tier 1 Risk-Based Capital $ 11,878 19.8 % $ 3,894 6.5 % $ 2,696 4.5 %  Tier 1 Risk-Based Capital 11,878 19.8 % 4,793 8.0 % 3,595 6.0 %  Total Risk-Based Capital 11,904 19.9 % 5,992 10.0 % 4,793 8.0 %  Tier 1 Leverage 11,878 7.0 % 8,456 5.0 % 6,765 4.0 %  December 31, 2015  CSC  Common Equity Tier 1 Risk-Based Capital $ 10,851 18.2 % N/A $ 2,681 4.5 %  Tier 1 Risk-Based Capital 12,310 20.7 % N/A 3,575 6.0 %  Total Risk-Based Capital 12,342 20.7 % N/A 4,766 8.0 %  Tier 1 Leverage 12,310 7.1 % N/A 6,912 4.0 %  Schwab Bank  Common Equity Tier 1 Risk-Based Capital $ 9,314 18.1 % $ 3,349 6.5 % $ 2,318 4.5 %  Tier 1 Risk-Based Capital 9,314 18.1 % 4,121 8.0 % 3,091 6.0 %  Total Risk-Based Capital 9,345 18.1 % 5,152 10.0 % 4,121 8.0 %  Tier 1 Leverage 9,314 7.1 % 6,594 5.0 % 5,275 4.0 %  N/A Not Applicable. Based on its regulatory capital ratios at December 31, 2016, Schwab Bank is considered well capitalized (the highest category) under its respective regulatory capital rules. There are no conditions or events since December 31, 2016 that management believes have changed Schwab Bank’s capital category.  The Federal Reserve requires Schwab Bank to maintain reserve balances at the Federal Reserve based on its deposits that are considered to be transaction accounts. Schwab Bank’s average reserve requirements were $1.5 billion and $1.4 billion in 2016 and 2015, respectively.  Beginning on January 1, 2016, CSC and Schwab Bank became subject to a new capital conservation buffer requirement of .625% of risk-weighted assets, increasing each year by .625% until fully implemented at 2.5% of risk-weighted assets in January 2019. The capital conservation buffer is in addition to the minimum risk-based capital requirements described above. Failure to maintain the capital conservation buffer would limit an entity’s ability to make capital distributions and discretionary bonus payments to executive officers. At December 31, 2016, both CSC’s and Schwab Bank’s capital levels exceeded the fully implemented capital conservation buffer requirement.  CSC’s principal broker-dealers are Schwab and optionsXpress. Schwab and optionsXpress are both subject to Rule 15c3-1 under the Securities Exchange Act of 1934 (the Uniform Net Capital Rule). Schwab and optionsXpress compute net capital under the alternative method permitted by the Uniform Net Capital Rule. This method requires the maintenance of minimum net capital, as defined, of the greater of 2% of aggregate debit balances arising from client transactions or a minimum dollar requirement ($250,000) , which is based on the type of business conducted by the broker-dealer. Under the alternative method, a broker-dealer may not repay subordinated borrowings, pay cash dividends, or make any unsecured advances or loans if such payment would result in a net capital amount of less than 5% of aggregate debit balances or less than 120% of its minimum dollar requirement.  optionsXpress is also subject to Commodity Futures Trading Commission Regulation 1.17 (Reg. 1.17) under the Commodity Exchange Act, which also requires the maintenance of minimum net capital. optionsXpress, as a futures commission merchant, is required to maintain minimum net capital equal to the greater of its net capital requirement under Reg. 1.17 ( $1 million), or the sum of 8% of the total risk margin requirements for all positions carried in client accounts and 8% of the total risk margin requirements for all positions carried in non-client accounts (as defined in Reg. 1.17).  Net capital and net capital requirements for Schwab and optionsXpress are as follows:    Net Capital  Minimum 2% of in Excess of  Net Capital Aggregate Required  December 31, 2016 Net Capital Required Debit Balances Net Capital  Schwab $ 1,846 $ 0.250 $ 355 $ 1,491  optionsXpress 269 1 8 261  December 31, 2015  Schwab $ 1,746 $ 0.250 $ 358 $ 1,388  optionsXpress 244 1 7 237  Schwab and optionsXpress are also subject to Rule 15c3-3 under the Securities Exchange Act of 1934 and other applicable regulations, which require them to maintain cash or qualified securities in a segregated reserve account for the exclusive benefit of clients. In accordance with Rule 15c3-3, Schwab and optionsXpress had portions of their cash and investments segregated for the exclusive benefit of clients at December 31, 2016 . Amounts included in cash and investments segregated and on deposit for regulatory purposes represent actual balances on deposit, whereas cash and investments required to be segregated and on deposit for regulatory purposes at December 31, 2016 for Schwab and optionsXpress totaled $23.3 billion. On January 4, 2017, Schwab and optionsXpress deposited a net amount of $1.6 billion of cash into their segregated reserve bank accounts. Cash and investments required to be segregated and on deposit for regulatory purposes at December 31, 2015 for Schwab and optionsXpress totaled $20.5 billion. On January 5, 2016, Schwab and optionsXpress deposited a net amount of $1.4 billion of cash into their segregated reserve bank accounts.

Segment Information [Abstract]
Segment Information	23. Segment Information  The Company’s two reportable segments are Investor Services and Advisor Services. The Company structures its operating segments according to its clients and the services provided to those clients. The Investor Services segment provides retail brokerage and banking services, retirement plan services, and other corporate brokerage services. The Advisor Services segment provides custodial, trading, banking, and support services as well as retirement business services. Revenues and expenses are allocated to the Company’s two segments based on which segment services the client.  The accounting policies of the segments are the same as those described in Note 2. For the computation of its segment information, the Company utilizes an activity-based costing model to allocate traditional income statement line item expenses (e.g., compensation and benefits, depreciation and amortization, and professional services) to the business activities driving segment expenses (e.g., client service, opening new accounts, or business development) and a funds transfer pricing methodology to allocate certain revenues.  The Company evaluates the performance of its 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 Company’s reportable segments is presented in the following table:    Investor Services (1) Advisor Services (1) Unallocated Total  Year Ended December 31, 2016 2015 2014 2016 2015 2014 2016 2015 2014 2016 2015 2014  Net Revenues:  Asset management and  administration fees $ 2,093 $ 1,837 $ 1,742 $ 962 $ 813 $ 791 $ - $ - $ - $ 3,055 $ 2,650 $ 2,533  Net interest revenue 2,591 2,133 2,028 731 392 244 - - - 3,322 2,525 2,272  Trading revenue 524 556 606 301 310 301 - - - 825 866 907  Other (2) 199 234 218 72 94 74 - - 51 271 328 343  Provision for loan losses 4 11 4 1 - - - - - 5 11 4  Net impairment losses  on securities - - (1) - - - - - - - - (1)  Total net revenues 5,411 4,771 4,597 2,067 1,609 1,410 - - 51 7,478 6,380 6,058  Expenses Excluding Interest (3) 3,380 3,090 2,937 1,105 1,011 938 - - 68 4,485 4,101 3,943  Income before taxes on income $ 2,031 $ 1,681 $ 1,660 $ 962 $ 598 $ 472 $ - $ - $ (17) $ 2,993 $ 2,279 $ 2,115   Capital expenditures $ 234 $ 195 $ 271 $ 119 $ 90 $ 134 $ - $ - $ - $ 353 $ 285 $ 405  Depreciation and amortization $ 180 $ 171 $ 154 $ 54 $ 53 $ 45 $ - $ - $ - $ 234 $ 224 $ 199   (1) The Corporate Brokerage Retirement Services business was transferred from the Investor Services segment to the Advisor Services segment in the fourth quarter of 2015.

Summary of Significant Accounting Policies [Abstract]
Asset management and administration fees	Asset management and administration fees  Asset management and administration fees include mutual fund and ETF service fees and fees for other asset-based financial services provided to individual and institutional clients, and are recognized as revenue over the period that the related service is provided, based upon daily average asset balances. The Company’s policy is to recognize revenue subject to refunds because management can estimate refunds based on Company specific experience. Actual refunds were not material as of December 31, 2016 and for all years presented. The Company earns mutual fund and ETF service fees for shareholder services, administration, and investment management provided to its proprietary funds, and recordkeeping and shareholder services provided to third-party funds. Asset management and administration fees are based upon the daily balances of client assets invested in these funds. The fair values of client assets included in proprietary and third-party mutual funds and ETFs are based on quoted market prices and other observable market data. The Company also earns asset management fees for advice solutions, which include managed portfolios, specialized strategies and customized investment advice. Other asset management and administration fees include various asset-based fees, such as trust fees, 401(k) recordkeeping fees, mutual fund clearing fees, collective trust fund fees, and non-balance based service and transaction fees.
Interest revenue	Interest revenue  Interest revenue represents interest earned on cash and cash equivalents, segregated cash and investments, receivables from brokers, dealers, and clearing organizations, receivables from brokerage clients, other securities owned, investment securities, and bank loans. Interest revenue is recognized in the period earned based upon average or daily asset balances and respective interest rates.
Trading revenue	Trading revenue  Trading revenue includes commission and principal transaction revenues. Commission revenue is affected by the number of revenue trades executed and the average revenue earned per revenue trade. Principal transaction revenue is primarily comprised of revenue from trading activity in fixed income securities with clients. To accommodate clients’ fixed income trading activity, the Company maintains positions in fixed income securities, including U.S. state and municipal debt obligations, U.S. Government and corporate debt, and other securities. The difference between the price at which the Company buys and sells securities to and from its clients and other broker-dealers is recognized as principal transaction revenue. Principal transaction revenue also includes adjustments to the fair value of these securities positions.
Cash and cash equivalents	Cash and cash equivalents  The Company considers all highly liquid investments with original maturities of three months or less that are not segregated and on deposit for regulatory purposes to be cash equivalents. Cash and cash equivalents include money market funds, deposits with banks, certificates of deposit, commercial paper, and U.S. Treasury securities. Cash and cash equivalents also include balances that Schwab Bank maintains at the Federal Reserve Bank.
Cash and investments segregated and on deposit for regulatory purposes	Cash and investments segregated and on deposit for regulatory purposes  Cash and investments segregated and on deposit for regulatory purposes include securities purchased under agreements to resell (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 control of 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. Pursuant to applicable regulations, client cash balances not used for margin lending are segregated into investment accounts maintained for the exclusive benefit of clients by the Company’s broker-dealer subsidiaries.
Receivables from brokerage clients	Receivables from brokerage clients  Receivables from brokerage clients includes 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 doubtful accounts. The Company monitors margin levels and requires clients to deposit additional collateral, or reduce margin positions to meet minimum collateral requirements if the fair value of the collateral changes. Receivables from brokerage clients that remain unsecured or partially secured for more than 30 days are fully reserved for in the allowance for doubtful accounts, except in the case of confirmed fraud, which is reserved immediately. Clients with margin loans have agreed to allow the Company to pledge collateralized securities in accordance with federal regulations. The collateral is not reflected in the consolidated financial statements.
Other securities owned	Other securities owned  Other securities owned are recorded at fair value based on quoted market prices or other observable market data. Unrealized gains and losses are included in trading revenue.
Investment Securities	Investment Securities  AFS securities are recorded at fair value and unrealized gains and losses are reported, net of taxes, in AOCI included in stockholders’ equity. HTM securities are recorded at amortized cost based on the Company’s positive intent and ability to hold these securities to maturity. Realized gains and losses from sales of AFS securities are determined on a specific identification basis and are included in other revenue.  Management evaluates whether investment securities are OTTI on a quarterly basis. Debt securities with unrealized losses are considered OTTI if the Company intends to sell the security or if it is more likely than not that the Company will be required to sell such security before any anticipated recovery. If management determines that a security is OTTI under these circumstances, the impairment recognized in earnings is measured as the entire difference between amortized cost and fair value.  A security is also OTTI if management does not expect to recover all of the amortized cost of the security. In this circumstance, the impairment recognized in earnings represents the estimated credit loss, and is measured by the difference between the present value of expected cash flows and the amortized cost of the security. Where appropriate, management utilizes cash flow models to estimate the expected future cash flow from the securities to estimate the credit loss. Expected cash flows are discounted using the security’s effective interest rate.  The evaluation of whether the Company expects to recover the amortized cost of a security is inherently judgmental. The evaluation includes the consideration of multiple factors including: the magnitude and duration of the unrealized loss; the financial condition of the issuer; the payment structure of the security; external credit ratings; internal credit ratings; 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 the Company has received all scheduled principal and interest payments.
Securities borrowed and securities loaned	Securities borrowed and securities loaned  Securities borrowed require the Company to deliver cash to the lender in exchange for securities and are included in receivables from brokers, dealers, and clearing organizations. For securities loaned, the Company receives collateral in the form of cash in an amount equal to or greater than the market value of securities loaned. Securities loaned are included in payables to brokers, dealers, and clearing organizations. The Company monitors the market value of securities borrowed and loaned, with additional collateral obtained or refunded to ensure full collateralization. Fees received or paid are recorded in interest revenue or interest expense.
Bank loans and related allowance for loan losses	Bank loans and related allowance for loan 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, loans are recorded net of an allowance for loan losses. The Company’s loan portfolio includes four loan types: First Mortgages, HELOCs, PALs and other loans. Loan segments are defined as the level to which the Company disaggregates its loan types when developing and documenting a methodology for determining the allowance for loan losses.  PALs are collateralized by marketable securities with liquid markets. Credit lines are over-collateralized dependent on the type of security pledged. Collateral market value is monitored on a daily basis and a borrower’s committed line may be reduced or collateral may be liquidated if the collateral is in danger of falling below specified levels. As such, the loss inherent within this portfolio is limited.  The Company records an allowance for loan losses through a charge to earnings based on management’s estimate of probable losses in the existing portfolio. Management reviews the allowance for loan losses quarterly, taking into consideration current economic conditions, the composition of the existing loan portfolio, past loss experience, and risks inherent in the portfolio to ensure that the allowance for loan losses is maintained at an appropriate level .  The methodology to establish an allowance for loan losses utilizes statistical models that estimate prepayments, defaults, and probable losses for the loan segments based on predicted behavior of individual loans within the segments. The methodology considers the effects of borrower behavior and a variety of factors including, but not limited to, interest rates, housing price movements as measured by a housing price index, economic conditions, estimated defaults and foreclosures measured by historical and expected delinquencies, changes in prepayment speeds, LTV ratios, past loss experience, estimates of future loss severities, borrower credit risk, and the adequacy of collateral. The methodology also evaluates concentrations in the loan types, including loan products within those types, year of origination, and geographical distribution of collateral.  Probable 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 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, and interest rates. Delinquency roll rates (i.e., the rates at which loans transition through delinquency stages and ultimately result in a loss) are estimated from the Company’s historical loss experience adjusted for current trends and market information. Loss severity estimates are based on the Company’s historical loss experience and market trends. The estimated loss severity (i.e., loss given default) used in the allowance for loan loss methodology for HELOC loans 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.  This methodology results in loss factors that are applied to the outstanding balances to determine the allowance for loan loss for each loan type.  The Company considers loan modifications in which it makes an economic concession to a borrower experiencing financial difficulty to be troubled debt restructurings (TDR).
Nonaccrual, nonperforming and impaired loans	Nonaccrual, Nonperforming and Impaired loans  First Mortgages, HELOCs, PALs, and other 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. For the portion of the HELOC portfolio for which the Company is able to track the delinquency status on the associated first lien loan, the Company places a HELOC on non-accrual status if the associated first mortgage is 90 days or more delinquent, regardless of the payment status of the HELOC. When a loan is placed on nonaccrual status, the accrued and unpaid interest receivable is reversed 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. Nonaccrual loans, other real estate owned, and TDRs are considered impaired assets, as it is probable the Company will not collect all amounts due.
Loan Charge-Offs	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 loan losses and the loan balance. The Company’s 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 or not 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.
Equipment, office facilities, and property	Equipment, office facilities, and property  Equipment, office facilities, and property are recorded at cost net of accumulated depreciation and amortization, except for land, which is recorded at cost. Equipment and office facilities are depreciated on a straight-line basis over an estimated useful life of five to ten years. Buildings are depreciated on a straight-line basis over 20 to 40 years. Leasehold improvements are amortized on a straight-line basis over the shorter of the estimated useful life of the asset or the term of the lease. Software and certain costs incurred for purchasing or developing software for internal use are amortized on a straight-line basis over an estimated useful life of three or five years. Equipment, office facilities, and property are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable.
Goodwill	Goodwill  Goodwill represents the fair value of acquired businesses in excess of the fair value of the individually identified net assets acquired. Goodwill is not amortized but is tested for impairment annually or whenever indications of impairment exist. The Company’s annual impairment testing date is April 1 st . The Company can elect to qualitatively assess goodwill for impairment if it is more likely than not that the fair value of a reporting unit exceeds its carrying value.  If the Company elects to bypass qualitatively assessing goodwill, or it is not more likely than not that the fair value of a reporting unit exceeds its carrying value, management estimates the fair values of each of the Company’s reporting units (defined as the Company’s businesses for which financial information is available and reviewed regularly by management) and compares it to their carrying values. Based on the Company’s analysis, fair value significantly exceeded the carrying value for all reporting units as of its annual testing date.
Intangible assets	Intangible assets  Intangible assets are amortized over their useful lives in a manner that best reflects their economic benefit. Intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. The Company does not have any indefinite-lived intangible assets.
Low-Income Housing Tax Credit (LIHTC) Investments	Low-Income Housing Tax Credit (LIHTC) Investments  As part of the Company’s community reinvestment initiatives, the Company invests with other institutional investors in funds that make equity investments in multifamily affordable housing properties. The Company receives tax credits and other tax benefits for these investments. The Company accounts for investments in qualified affordable housing projects using the proportional amortization method if certain criteria are met. The proportional amortization method amortizes the cost of the investment over the period in which the investor expects to receive tax credits and other tax benefits, and the resulting amortization is recognized as a component of income tax expense attributable to continuing operations. The carrying value of LIHTC investments is included in other assets on the consolidated balance sheets. Unfunded commitments related to LIHTC investments are included in accrued expenses and other liabilities on the consolidated balance sheets.
Guarantees and indemnifications	Guarantees and indemnifications  The Company recognizes, at the inception of a guarantee, a liability equal to the estimated fair value of the obligation undertaken in issuing the guarantee. The fair values of obligations relating to guarantees are estimated based on transactions for similar guarantees or expected present value measures.
Advertising and market development	Advertising and market development  Advertising and market development activities include the cost to produce and distribute marketing campaigns as well as client incentives and discounts. Such costs are generally expensed when incurred.
Income taxes	Income taxes  The Company provides for income taxes on all transactions that have been recognized in the consolidated financial statements. Accordingly, deferred tax assets are adjusted to reflect the tax rates at which future taxable amounts will likely be settled or realized. The effects of tax rate changes on future deferred tax assets and deferred tax liabilities, as well as other changes in income tax laws, are recorded in earnings in the period during which such changes are enacted. The Company’s unrecognized tax benefits, which are included in accrued expenses and other liabilities, represent the difference between positions taken on tax return filings and estimated potential tax settlement outcomes. Accrued interest relating to unrecognized tax benefits is recorded in income tax expense and penalties are recorded in other expense.
Share-based compensation	Share-based compensation  Share-based compensation includes employee and board of director stock options and restricted stock units. The Company measures compensation expense for these share-based payment arrangements based on their estimated fair values as of the unit’s grant date. The fair value of the share-based award is recognized over the vesting period as share-based compensation. Share-based compensation expense is based on units expected to vest and therefore is reduced for estimated forfeitures. Forfeitures are estimated at the time of grant based on the Company’s historical forfeiture experience and revised in subsequent periods if actual forfeitures differ from those estimates. The excess tax benefits from the exercise of stock options and the vesting of restricted stock units are recorded in additional paid-in capital.
Fair values of assets and liabilities	Fair values of assets and liabilities  Fair value is defined as the price that would be received to sell an asset or the price paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurement accounting guidance describes the fair value hierarchy for disclosing assets and liabilities measured at fair value based on the inputs used to value them. The fair value hierarchy maximizes the use of observable inputs and minimizes the use of unobservable inputs. Observable inputs are based on market pricing data obtained from sources independent of the Company. A quoted price in an active market provides the most reliable evidence of fair value and is generally used to measure fair value whenever available.  Unobservable inputs reflect management’s judgment about the assumptions market participants would use in pricing the asset or liability. Where inputs used to measure fair value of an asset or liability are from different levels of the hierarchy, the asset or liability is categorized based on the lowest level input that is significant to the fair value measurement in its entirety. Assessing the significance of a particular input requires judgment. The fair value hierarchy includes three levels based on the objectivity of the inputs as follows:  · Level 1 inputs are quoted prices in active markets as of the measurement date for identical assets or liabilities that the Company has the ability to access.  · Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets and liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates, benchmark yields, issuer spreads, new issue data, and collateral performance.  · Level 3 inputs are unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability.  The Company’s policy is to recognize transfers of financial instruments between levels as of the beginning of the reporting period in which a transfer occurs.  Assets and liabilities measured at fair value on a recurring basis  The Company’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, other securities owned, and AFS securities. 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. 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 do not exist, the Company uses prices obtained from independent third-party pricing services to measure the fair value of investment assets. The Company generally obtains prices from at least three independent pricing sources for assets recorded at fair value.  The Company’s primary independent pricing service provides prices based on observable trades 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. The Company compares the prices obtained from its 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. The Company 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 a material difference in the recorded amounts.  Fair value of other financial instruments  Descriptions of the valuation methodologies and assumptions used to estimate the fair value of other financial instruments are described below. The Company’s financial instruments not recorded at fair value but for which fair value can be approximated and disclosed include:  · Cash and cash equivalents are short-term in nature and accordingly are recorded at amounts that approximate fair value.  · Cash and investments segregated and on deposit for regulatory purposes include cash and securities purchased under resale agreements. Securities purchased under resale agreements are short-term in nature and are backed by collateral that both exceeds the carrying value of the resale agreement and is highly liquid in nature. Accordingly, the carrying values of these financial instruments approximate their fair values.  · Receivables from/payables to brokers, dealers, and clearing organizations are short-term in nature, recorded at contractual amounts and historically have been settled at those values. Accordingly, the carrying values of these financial instruments approximate their fair values.  · Receivables from/payables to brokerage clients — net are short-term in nature, recorded at contractual amounts and historically have been settled at those values. Accordingly, the carrying values of these financial instruments approximate their fair values.  · HTM securities – The fair values of HTM securities are obtained using an independent third-party pricing service similar to investment assets recorded at fair value as discussed above.  · Bank loans – The fair values of the Company’s First Mortgages and HELOCs are estimated based on prices of mortgage-backed securities collateralized by similar types of loans. PALs are non-purpose revolving lines of credit secured by eligible assets; accordingly, the carrying values of these loans approximate their fair values.  · Financial instruments included in other assets primarily consist of LIHTC investments, cost method investments and FHLB stock, whose carrying values approximate their fair values. FHLB stock is recorded at par, which approximates its fair value.  · Bank deposits have no stated maturity and are recorded at the amount payable on demand as of the balance sheet date. The Company considers the carrying values of these deposits to approximate their fair values.  · Financial instruments included in accrued expenses and other liabilities consist of drafts payable and certain amounts due under contractual obligations, including unfunded LIHTC commitments. The carrying values of these instruments approximate their fair values.  · Short-term borrowings consist of commercial paper and funds drawn on Schwab Bank’s secured credit facility with the Federal Home Loan Bank of San Francisco. Due to the short-term nature of these borrowings, carrying value approximates fair value.  · Long-term debt – Except for the finance lease obligation, the fair values of long-term debt are estimated using indicative, non-binding quotes from independent brokers. The Company validates indicative prices for its debt through comparison to other independent non-binding quotes. The finance lease obligation is recorded at carrying value, which approximates fair value.  · Firm commitments to extend credit – The Company extends credit to banking clients through HELOCs and PALs. The Company considers the fair value of these unused commitments to not be material because the interest rates earned on these balances are based on floating interest rates that reset monthly. 
Adoption of New Accounting Standards	Adoption of New Accounting Standards  On January 1, 2016, the Company adopted ASU 2015-02, “Consolidation (Topic 810),” which amends the analysis a reporting entity must perform to determine whether it should consolidate certain types of legal entities. The new guidance is applicable to all entities but provides an exception for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. The adoption of ASU 2015-02 did not have an impact on the Company’s consolidated financial statements or EPS, as the new guidance did not change any consolidation conclusions reached in accordance with the previous guidance.  On January 1, 2016, the Company adopted ASU 2015-03, “Interest – Imputation of Interest (Subtopic 835-30).” ASU 2015-03 requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. Previously, debt issuance costs were presented as a separate asset on the balance sheet. The guidance in ASU 2015-03 has been applied on a retrospective basis, which requires the adjustment of all prior period consolidated balance sheets. The effect of the adoption on the Company’s December 31, 2015 consolidated balance sheet was to decrease other assets and total assets by $13 million and to decrease long-term debt and total liabilities by $13 million. The Company considers the reclassifications immaterial.  On January 1, 2016, the Company also adopted ASU 2015-05, “Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40),” which provides new guidance that clarifies customers’ accounting for fees paid in a cloud computing arrangement. Under the new guidance, if a cloud computing arrangement includes a software license, the customer shall account for the software license element of the arrangement consistent with the acquisition of other software licenses. If the cloud computing arrangement does not include a software license, the customer shall account for the arrangement as a service contract. The guidance applies to all new arrangements entered into after January 1, 2016. The adoption of ASU 2015-05 did not have an impact on the Company’s financial statements or EPS.
New Accounting Standards Not Yet Adopted	New Accounting Standards Not Yet Adopted  In May 2014, the Financial Accounting Standards Board (FASB) issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” which provides new guidance on revenue recognition. The guidance clarifies that revenue from contracts with customers should be recognized in a manner that depicts the timing of the related transfer of goods or performance of services at an amount that reflects the expected consideration. The FASB has subsequently issued several amendments to the standard, including deferral of the effective date until January 1, 2018, clarification of principal versus agent considerations, narrow scope improvements and other technical corrections. Entities may elect either full or modified retrospective transition. Full retrospective transition will require a cumulative effect adjustment to retained earnings as of the earliest comparative period presented. Modified retrospective transition will require a cumulative effect adjustment to retained earnings as of the beginning of the reporting period in which the entity first applies the new guidance.  The Company plans to adopt the revenue recognition guidance in the first quarter of 2018. The guidance does not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other U.S. GAAP. Accordingly, the Company does not expect an impact to net interest revenue. While the Company has not yet identified any changes in the timing of revenue recognition, the Company’s review is ongoing. The Company is evaluating the impact the new standard will have on the presentation of certain revenue streams (gross versus net reporting) and the capitalization of contract costs. The Company has not yet selected a transition method and continues to evaluate the impact the new guidance will have on its financial statements and EPS.  In January 2016, the FASB issued ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10),” which will become effective January 1, 2018. This new guidance addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The main provisions of the guidance include (i) most equity investments are to be measured at fair value with changes in fair value recognized in net income, except for those accounted for under the equity method or those that do not have readily determinable fair values for which a practical expedient can be elected, (ii) requires the use of an exit price notion when measuring the fair value of financial instruments for disclosure purposes, and (iii) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial instrument on the balance sheet or in the accompanying notes. The Company does not expect the adoption of ASU 2016-01 will have a material impact on its financial statements and EPS.  In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” which amends the accounting for leases by lessees and lessors. The primary change as a result of the new standard is the recognition of right-of-use assets and lease liabilities by lessees for those leases classified as operating leases. Additional changes include accounting for lease origination and executory costs, required lessee reassessments during the lease term due to changes in circumstances and expanded lease disclosures. ASU 2016-02 will become effective January 1, 2019, with early adoption permitted, and requires entities to apply the new guidance using a modified retrospective transition. Modified retrospective transition requires entities to apply the new guidance as of the beginning of the earliest comparative period presented in the financial statements in which the entity first applies the new standard. Certain transition reliefs are permitted if elected by the entity. The adoption of ASU 2016-02 will result in the Company recognizing a right-of-use asset and lease liability on the consolidated balance sheet based on the present value of remaining operating lease payments (see Note 14 for the undiscounted future annual minimum rental commitments for operating leases). The Company does not expect the adoption of ASU 2016-02 will have a material impact on its EPS.  In March 2016, the FASB issued ASU 2016-09, “Stock Compensation – Improvements to Employee Share-Based Payment Accounting (Topic 718)” which amends certain aspects of how an entity accounts for share-based payments to employees. The new guidance requires entities to recognize the income tax effects for the difference between GAAP and federal income tax treatment of share-based awards in the income statement when the awards vest or are settled, rather than recording such effects in additional paid-in capital. Entities will also be permitted to elect to account for forfeitures of share-based payments as they occur or continue with current practice, which requires estimating the number of awards expected to be forfeited and adjusting the estimate when it is likely to change. ASU 2016-09 became effective January 1, 2017. The change in recognition of income tax effects of share-based awards will be applied prospectively. If an entity elects to account for forfeitures of share-based payments as they occur, such change will be applied using a modified retrospective transition method, with a cumulative-effect adjustment to retained earnings. The adoption of ASU 2016-09 will result in the Company recognizing the income tax effects of share-based awards in the income statement, thus impacting the Company’s EPS on a prospective basis. The impact of this new guidance is largely dependent on the Company’s future share price at the date of restricted stock unit vest or option exercise and, thus, is not practicable to estimate. The impact of ASU 2016-09 will likely disproportionately occur during the fourth quarter of each year due to the Company’s historic practice of granting the majority of equity compensation in that period. For historical perspective only, if ASU 2016-09 had been in effect for year ended 2016, the Company’s taxes on income as presented in the consolidated statements of income would have been reduced by $48 million and EPS increased by $0.04 .  In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” which provides new guidance for recognizing impairment of most debt instruments measured at amortized cost, including loans and HTM debt securities. The new guidance will require estimating 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. The new guidance also amends the 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. ASU 2016-13 will become effective January 1, 2020, with early adoption permitted as of January 1, 2019. The new guidance will be applied 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 had been recognized before the effective date. The Company is currently evaluating the impact of this new guidance on its financial statements and EPS.
