Organization, Consolidation and Presentation of Financial Statements [Abstract]
Introduction and Basis of Presentation	Introduction and Basis of Presentation The Firm Morgan Stanley is a global financial services firm that maintains significant market positions in each of its business segments—Institutional Securities, Wealth Management and Investment Management. Morgan Stanley, through its subsidiaries and affiliates, provides a wide variety of products and services to a large and diversified group of clients and customers, including corporations, governments, financial institutions and individuals. Unless the context otherwise requires, the terms “Morgan Stanley” or the “Firm” mean Morgan Stanley (the “Parent Company”) together with its consolidated subsidiaries. See the “Glossary of Common Terms and Acronyms” for the definition of certain terms and acronyms used throughout this Form 10-Q. A description of the clients and principal products and services of each of the Firm’s business segments is as follows: Institutional Securities provides investment banking, sales and trading, lending and other services to corporations, governments, financial institutions and high to ultra-high net worth clients. Investment banking services consist of capital raising and financial advisory services, including services relating to the underwriting of debt, equity and other securities, as well as advice on mergers and acquisitions, restructurings, real estate and project finance. Sales and trading services include sales, financing, prime brokerage and market-making activities in the equity and fixed income businesses. Lending activities include originating corporate loans and commercial real estate loans, providing secured lending facilities, and extending financing to sales and trading customers. Other activities include Asia wealth management services, investments and research. Wealth Management provides a comprehensive array of financial services and solutions to individual investors and small to medium-sized businesses and institutions covering: brokerage and investment advisory services; financial and wealth planning services; stock plan administration services; annuity and insurance products; securities-based lending, residential real estate loans and other lending products; banking; and retirement plan services. Investment Management provides a broad range of investment strategies and products that span geographies, asset classes, and public and private markets to a diverse group of clients across institutional and intermediary channels. Strategies and products, which are offered through a variety of investment vehicles, include equity, fixed income, liquidity and alternative/other products. Institutional clients include defined benefit/defined contribution plans, foundations, endowments, government entities, sovereign wealth funds, insurance companies, third-party fund sponsors and corporations. Individual clients are generally served through intermediaries, including affiliated and non-affiliated distributors. Basis of Financial Information The financial statements are prepared in accordance with U.S. GAAP, which requires the Firm to make estimates and assumptions regarding the valuations of certain financial instruments, the valuations of goodwill and intangible assets, the outcome of legal and tax matters, deferred tax assets, ACL, and other matters that affect its financial statements and related disclosures. The Firm believes that the estimates utilized in the preparation of its financial statements are prudent and reasonable. Actual results could differ materially from these estimates. Certain reclassifications have been made to prior periods to conform to the current presentation. The Notes are an integral part of the Firm's financial statements. The Firm has evaluated subsequent events for adjustment to or disclosure in these financial statements through the date of this report and has not identified any recordable or disclosable events not otherwise reported in these financial statements or the notes thereto. The accompanying financial statements should be read in conjunction with the Firm’s financial statements and notes thereto included in the 2019 Form 10-K . Certain footnote disclosures included in the 2019 Form 10-K have been condensed or omitted from these financial statements as they are not required for interim reporting under U.S. GAAP. The financial statements reflect all adjustments of a normal, recurring nature that are, in the opinion of management, necessary for the fair presentation of the results for the interim period. The results of operations for interim periods are not necessarily indicative of results for the entire year. Consolidation The financial statements include the accounts of the Firm, its wholly owned subsidiaries and other entities in which the Firm has a controlling financial interest, including certain VIEs (see Note 15 ). Intercompany balances and transactions have been eliminated. For consolidated subsidiaries that are not wholly owned, the third-party holdings of equity interests are referred to as noncontrolling interests. The net income attributable to noncontrolling interests for such subsidiaries is presented as Net income applicable to noncontrolling interests in the income statements. The portion of shareholders’ equity that is attributable to noncontrolling interests for such subsidiaries is presented as noncontrolling interests, a component of Total equity, in the balance sheets. For a discussion of the Firm’s significant regulated U.S. and international subsidiaries and its involvement with VIEs, see Note 1 to the financial statements in the 2019 Form 10-K .

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies For a detailed discussion about the Firm’s significant accounting policies and for further information on accounting updates adopted in the prior year, see Note 2 to the financial statements in the 2019 Form 10-K . During the nine months ended September 30, 2020 (“current year period”), there were no significant revisions to the Firm’s significant accounting policies, other than for the accounting updates adopted. Accounting Updates Adopted in 2020 Reference Rate Reform The Firm adopted the Reference Rate Reform accounting update in the current year period. There was no impact to the Firm’s financial statements upon initial adoption. This accounting update provides optional accounting relief to entities with contracts, hedge accounting relationships or other transactions that reference LIBOR or other interest rate benchmarks for which the referenced rate is expected to be discontinued or replaced. The Firm is applying the accounting relief as relevant contract and hedge accounting relationship modifications are made during the course of the reference rate reform transition period. The optional relief generally allows for contract modifications solely related to the replacement of the reference rate to be accounted for as a continuation of the existing contract instead of as an extinguishment of the contract, and would therefore not trigger certain accounting impacts that would otherwise be required. It also allows entities to change certain critical terms of existing hedge accounting relationships that are affected by reference rate reform, and these changes would not require de-designating the hedge accounting relationship. The optional relief ends December 31, 2022. Financial Instruments—Credit Losses The Firm adopted the Financial Instruments — Credit Losses accounting update on January 1, 2020. This accounting update impacted the impairment model for certain financial assets measured at amortized cost by requiring a CECL methodology to estimate expected credit losses over the entire life of the financial asset, recorded at inception or purchase. CECL replaced the loss model previously applicable to loans held for investment, HTM securities and other receivables carried at amortized cost, such as employee loans. The update also eliminated the concept of other-than-temporary impairment for AFS securities and instead requires impairments on AFS securities to be recognized in earnings through an allowance when the fair value is less than amortized cost and a credit loss exists, and through a permanent reduction of the amortized cost basis when the securities are expected to be sold before recovery of amortized cost. For certain portfolios, we determined that there are de minimus or zero expected credit losses, for example, for lending and financing transactions, such as Securities borrowed, Securities purchased under agreements to resell and certain other portfolios where collateral arrangements are being followed. Also, we have zero expected credit losses for certain financial assets based on the credit quality of the borrower or issuer, such as U.S. government and agency securities. At transition on January 1, 2020, the adoption of this accounting standard resulted in an increase in the allowance for credit losses of $131 million with a corresponding reduction in Retained earnings of $100 million , net of tax. The adoption impact was primarily attributable to a $124 million increase in the allowance for credit losses on employee loans. The following discussion highlights changes to the Firm’s accounting policies as a result of this adoption. Instruments Measured at Amortized Cost and Certain Off-Balance Sheet Credit Exposures Allowance for Credit Losses The ACL for financial instruments measured at amortized cost and certain off-balance sheet exposures ( e.g., HFI loans and lending commitments, HTM securities, customer and other receivables and certain guarantees) represents an estimate of expected credit losses over the entire life of the financial instrument. Factors considered by management when determining the ACL include payment status, fair value of collateral, expected payments of principal and interest, as well as internal or external information relating to past events, current conditions and reasonable and supportable forecasts. The Firm’s three forecasts include assumptions about certain macroeconomic variables including, but not limited to, U.S. gross domestic product, equity market indices, unemployment rates, as well as commercial real estate and home price indices. At the conclusion of the Firm’s reasonable and supportable forecast period of 13 quarters, there is a gradual reversion back to historical averages. The ACL is measured on a collective basis when similar risk characteristics exist for multiple instruments considering all available information relevant to assessing the collectability of cash flows. Generally, the Firm applies a probability of default/loss given default model for instruments that are collectively assessed, under which the ACL is calculated as the product of probability of default, loss given default and exposure at default. These parameters are forecast for each collective group of assets using a scenario-based statistical model and at the conclusion of the Firm’s reasonable and supportable forecast period, the parameters gradually revert back to historical averages. If the instrument does not share similar risk characteristics with other instruments, including when it is probable that the Firm will be unable to collect the full payment of principal and interest on the instrument when due, the ACL is measured on an individual basis. The Firm generally applies a discounted cash flow method for instruments that are individually assessed. The Firm may also elect to use an approach that considers the fair value of the collateral when measuring the ACL if the loan is collateral dependent ( i.e., repayment of the loan is expected to be provided substantially by the sale or operation of the underlying collateral and the borrower is experiencing financial difficulty). Additionally, the Firm can elect to use an approach to measure the ACL using the fair value of collateral where the borrower is required to, and reasonably expected to, continually adjust and replenish the amount of collateral securing the instrument to reflect changes in the fair value of such collateral. The Firm has elected to use this approach for certain securities-based loans, customer receivables representing margin loans, Securities purchased under agreements to resell and Securities borrowed. Credit quality indicators considered in developing the ACL include: • Corporate loans, Secured lending facilities, Commercial real estate loans and securities, and Other loans: Internal risk ratings developed by the Credit Risk Management Department which are refreshed at least annually, and more frequently as necessary. These ratings generally correspond to external ratings published by S&P. The Firm also considers transaction structure, including type of collateral, collateral terms, and position of the obligation within the capital structure. In addition, for Commercial real estate, the Firm considers property type and location, net operating income, LTV ratios, among others, as well as commercial real estate price and credit spread indices and capitalization rates. • Residential real estate loans: Loan origination Fair Isaac Corporation (“FICO”) credit scores as determined by independent credit agencies in the United States and loan-to-value (“LTV”) ratios. • Employee loans: Employment status, which includes those currently employed by the Firm and for which the Firm can deduct any unpaid amounts due to it through certain compensation arrangements; and those no longer employed by the Firm where such compensation arrangements are no longer applicable. For Securities-based loans, the Firm generally measures the ACL based on the fair value of collateral. Qualitative and environmental factors such as economic and business conditions, the nature and volume of the portfolio, and lending terms and the volume and severity of past due loans are also considered in the ACL calculations. Presentation of ACL and Provision for Credit Losses ACL Provision for credit losses Instruments measured at amortized cost ( e.g., HFI loans, HTM securities and customer and other receivables) Contra asset Other revenue Employee loans Contra asset Compensation and benefits expense Off-balance sheet instruments ( e.g., HFI lending commitments and certain guarantees) Other liabilities and accrued expenses Other expense Troubled Debt Restructurings (“TDRs”) The Firm may modify the terms of certain loans for economic or legal reasons related to a borrower’s financial difficulties by granting one or more concessions that the Firm would not otherwise consider. Such modifications are accounted for and reported as a TDR, except for certain modifications related to the Coronavirus Disease (“COVID-19”) as noted in “Modifications and Nonaccrual Status for Borrowers Impacted by COVID-19” herein. A loan that has been modified in a TDR is generally considered to be impaired and is evaluated individually. TDRs are also generally classified as nonaccrual and may be returned to accrual status only after the Firm expects repayment of the remaining contractual principal and interest and there is sustained repayment performance for a reasonable period. Nonaccrual The Firm places financial instruments on nonaccrual status if principal or interest is past due for a period of 90 days or more or payment of principal or interest is in doubt unless the obligation is well-secured and in the process of collection, or in certain cases when related to COVID-19 as noted in “Modifications and Nonaccrual Status for Borrowers Impacted by COVID-19” herein. For any instrument placed on nonaccrual status, the Firm reverses any unpaid interest accrued with an offsetting reduction to Interest income. Principal and interest payments received on nonaccrual instruments are applied to principal if there is doubt regarding the ultimate collectability of principal. If collection of the principal is not in doubt, interest income is realized on a cash basis. If neither principal nor interest collection is in doubt and the instruments are brought current, instruments are generally placed on accrual status and interest income is recognized using the effective interest method. Modifications and Nonaccrual Status for Borrowers Impacted by COVID-19 In the first quarter of 2020, the Firm elected to apply the guidance issued by Congress in the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) as well as by the U.S. banking agencies stating that certain concessions granted to borrowers that are current on existing loans, either individually or as part of a program for creditworthy borrowers who are experiencing short-term financial or operational problems as a result of COVID-19, generally would not be considered TDRs. Additionally, these loans generally would not be considered nonaccrual status unless collectability concerns exist despite the modification provided. For loans remaining on accrual status, the Firm elected to continue recognizing interest income during the modification periods. ACL Write-offs The Firm writes-off a financial instrument in the period that it is deemed uncollectible and records a reduction in the ACL and the balance of the financial instrument in the balance sheet. However, for accrued interest receivable balances that are separately recorded from the related financial instruments, the Firm's nonaccrual policy requires that accrued interest receivable be written off against Interest income when the related financial instrument is placed in nonaccrual status. Accordingly, the Firm elected not to measure an ACL for accrued interest receivables. However, in the case of loans which are modified as a result of COVID-19 and remain on accrual status due to the relief noted in “Modifications and Nonaccrual Status for Borrowers Impacted by COVID-19,” accrued interest receivable balances are assessed for any required ACL. Available-for-Sale (“AFS”) Investment Securities AFS securities are reported at fair value in the balance sheets. Interest income, including amortization of premiums and accretion of discounts, is included in Interest income in the Income statements. Unrealized gains are recorded in OCI and unrealized losses are recorded either in OCI or in Other revenues as described below. AFS securities in an unrealized loss position are first evaluated to determine whether there is an intent to sell or it is more likely than not the Firm will be required to sell before recovery of the amortized cost basis. If so, the entire unrealized loss is recognized in Other revenues, as any previously established ACL is written off and the amortized cost basis is written down to the fair value of the security. For all other AFS securities in an unrealized loss position, any portion of unrealized losses representing a credit loss is recognized in Other revenues and as an increase to the ACL for AFS securities, with the remainder of unrealized losses recognized in OCI. When considering whether a credit loss exists, relevant information as discussed in Note 2 of the 2019 Form 10-K is considered, except that with the adoption of Financial Instruments—Credit Losses in 2020 , the length of time the fair value has been less than the amortized cost basis is no longer considered. Presentation of ACL and Provision for Credit Losses ACL Provision for credit losses AFS securities Contra Investment securities Other revenue Nonaccrual & ACL Write-Offs on AFS Securities AFS securities follow the same nonaccrual and write-off guidance as discussed in “Instruments Measured at Amortized Cost and Certain Off-Balance Sheet Credit Exposures” herein, except as set forth in “Modifications and Nonaccrual Status for Borrowers Impacted by COVID-19.” Goodwill The Firm completed its annual goodwill impairment testing as of July 1, 2020. The Firm’s impairment testing did not indicate any goodwill impairment, as each of the Firm’s reporting units with goodwill had a fair value that was in excess of its carrying value.

Business Combinations [Abstract]
Acquisitions	Acquisitions Acquisition of E*TRADE On October 2, 2020, the Firm completed the acquisition of 100% of E*TRADE Financial Corporation (“E*TRADE”) in a stock-for-stock transaction, which is expected to increase the scale and breadth of the Wealth Management business segment. Given the recency of the closing, the purchase accounting analysis is still preliminary, however, the transaction is expected to result in the addition of approximately $77 billion in assets, inclusive of approximately $5 billion of Goodwill and $3 billion of Intangible assets. Total consideration for the transaction was approximately $ 11.9 billion , which principally consists of the $ 11 billion fair value of 233 million common shares issued from Common stock held in treasury, at an exchange ratio of 1.0432 per E*TRADE common share. In addition, the Firm issued Series M and Series N preferred shares with a fair value of approximately $ 0.7 billion in exchange for E*TRADE’s existing preferred stock. Planned Acquisition of Eaton Vance On October 8, 2020, the Firm entered into a definitive agreement under which it will acquire Eaton Vance Corp. (“Eaton Vance”) in a cash and stock transaction valued, as of the announcement, at approximately $7 billion , based on the closing price of the Firm’s common stock and the number of Eaton Vance’s fully diluted shares outstanding on October 7, 2020. Under the terms of the agreement, Eaton Vance common stockholders will receive $28.25 in cash and 0.5833 Morgan Stanley common shares for each Eaton Vance common share. In addition, Eaton Vance common shareholders will receive a one-time special cash dividend of $4.25 per share to be paid pre-closing by Eaton Vance. The acquisition is subject to customary closing conditions, and is expected to close in the second quarter of 2021.

Net transfers in the current year period reflect the largely offsetting impacts of transfers in of $857 million of equity margin loans and transfers out of $707 million of equity margin loans. The loans were transferred into Level 3 in the first quarter as the significance of the margin loan rate input increased as a result of reduced liquidity, and transferred out of Level 3 in the second quarter as liquidity conditions improved reducing the significance of the input. Level 3 instruments may be hedged with instruments classified in Level 1 and Level 2. The realized and unrealized gains or losses for assets and liabilities within the Level 3 category presented in the previous tables do not reflect the related realized and unrealized gains or losses on hedging instruments that have been classified by the Firm within the Level 1 and/or Level 2 categories. The unrealized gains (losses) during the period for assets and liabilities within the Level 3 category may include changes in fair value during the period that were attributable to both observable and unobservable inputs. Total realized and unrealized gains (losses) are primarily included in Trading revenues in the income statements. Additionally, in the previous tables, consolidations of VIEs are included in Purchases and deconsolidations of VIEs are included in Settlements.

A single amount is disclosed for range and average when there is no significant difference between the minimum, maximum and average. Amounts represent weighted averages except where simple averages and the median of the inputs are more relevant. 2. Includes derivative contracts with multiple risks ( i.e. , hybrid products) . The previous tables provide information on the valuation techniques, significant unobservable inputs, and the ranges and averages for each major category of assets and liabilities measured at fair value on a recurring and nonrecurring basis with a significant Level 3 balance. The level of aggregation and breadth of products cause the range of inputs to be wide and not evenly distributed across the inventory of financial instruments. Further, the range of unobservable inputs may differ across firms in the financial services industry because of diversity in the types of products included in each firm’s inventory. Generally, there are no predictable relationships between multiple significant unobservable inputs attributable to a given valuation technique. Other than as follows, during the current year period, there were no significant revisions made to the descriptions of the Firm’s significant unobservable inputs. For margin loans, the margin loan rate is the annualized rate that reflects the possibility of losses as a result of movements in the price of the underlying margin loan collateral. The rate is calibrated from the previously disclosed discount rate, credit spread and/or volatility measures. For a description of the Firm’s significant unobservable inputs and qualitative information about the effect of hypothetical changes in the values of those inputs, see Note 3 to the financial statements in the 2019 Form 10-K .

Investments in hedge funds may be subject to initial period lock-up or gate provisions, which restrict an investor from withdrawing from the fund during a certain initial period or restrict the redemption amount on any redemption date, respectively. Amounts in the previous table represent the Firm’s carrying value of general and limited partnership interests in fund investments, as well as any related performance-based fees in the form of carried interest. The carrying amounts are measured based on the NAV of the fund taking into account the distribution terms applicable to the interest held. This same measurement applies whether the fund investments are accounted for under the equity method or fair value. For a description of the Firm’s investments in private equity funds, real estate funds and hedge funds, which are measured based on NAV, see Note 3 to the financial statements in the 2019 Form 10-K . See Note 14 for information regarding general partner guarantees, which include potential obligations to return performance fee distributions previously received.

Gains and losses for Loans and Other assets—Other investments are classified in Other revenues. For other items, gains and losses are recorded in Other revenues if the item is held for sale; otherwise, they are recorded in Other expenses. 2. Nonrecurring changes in the fair value of loans and lending commitments were calculated as follows: for the held-for-investment category, based on the value of the underlying collateral; and for the held-for-sale category, based on recently executed transactions, market price quotations, valuation models that incorporate market observable inputs where possible, such as comparable loan or debt prices and CDS spread levels adjusted for any basis difference between cash and derivative instruments, or default recovery analysis where such transactions and quotations are unobservable. 3. Losses related to Other assets—Other investments were determined using techniques that included discounted cash flow models, methodologies that incorporate multiples of certain comparable companies and recently executed transactions. 4. Losses related to Other assets—Premises, equipment and software generally include impairments as well as write-offs related to the disposal of certain assets.

The provision (release) for lending commitments was $48 million in the current quarter and $16 million in the prior year quarter. The aggregate allowance for loans and lending commitments increased in the current year period , principally reflecting the provision for credit losses within the Institutional Securities business segment primarily resulting from the continued economic impact of COVID-19. This provision was the result of risks related to vulnerable sectors and higher downgrade sensitivity, changes in asset quality trends, as well as revisions to our forecasts reflecting expected future market and macroeconomic conditions . The base scenario used in our ACL models as of September 30, 2020 was generated using a combination of industry consensus economic forecasts, forward rates, and internally developed and validated models. Given the nature of our lending portfolio, the most sensitive model input is U.S. GDP. The base scenario, among other things, assumes a continued recovery in the last quarter of 2020 through 2021, supported by fiscal stimulus and monetary policy measures. For a further discussion of the Firm’s loans as well as the Firm’s allowance methodology prior to the adoption of CECL, refer to Notes 2 and 8 to the financial statements in the 2019 Form 10-K . See Note 5 for further information regarding Loans and lending commitments held at fair value. See Note 14 for details of current commitments to lend in the future.

These loans are predominantly current. 2. These loans are predominantly past due for a period of 90 days or more. 3. The change in ACL includes a $124 million increase due to the adoption of CECL in the first quarter of 2020. Employee loans are granted in conjunction with a program established primarily to recruit certain Wealth Management representatives, are full recourse and generally require periodic repayments, and are due in full upon termination of employment with the Firm. These loans are recorded in Customer and other receivables in the balance sheets. The ACL as of September 30, 2020 was calculated under the CECL methodology, while the ACL at December 31, 2019 was calculated under the prior incurred loss model. The related provision is recorded in Compensation and benefits expense in the income statements. See Note 2 for a description of the CECL allowance methodology, including credit quality indicators, for employee loans.

These commitments relate to the Firm’s membership in certain clearinghouses and are contingent upon the default of a clearinghouse member or other stress events. Since commitments associated with these instruments may expire unused, the amounts shown do not necessarily reflect the actual future cash funding requirements. For a further description of these commitments, refer to Note 13 to the financial statements in the 2019 Form 10-K .

As of September 30, 2020 , the carrying amount of standby letters of credit and other financial guarantees issued includes an allowance for credit losses of $86 million . 2. The carrying amounts of derivative contracts that meet the accounting definition of a guarantee are shown on a gross basis. For further information on derivatives contracts, see Note 7 . 3. Primarily related to residential mortgage securitizations. The Firm has obligations under certain guarantee arrangements, including contracts and indemnification agreements, that contingently require the Firm to make payments to the guaranteed party based on changes in an underlying measure (such as an interest or foreign exchange rate, security or commodity price, an index, or the occurrence or non-occurrence of a specified event) related to an asset, liability or equity security of a guaranteed party. Also included as guarantees are contracts that contingently require the Firm to make payments to the guaranteed party based on another entity’s failure to perform under an agreement, as well as indirect guarantees of the indebtedness of others. Client Clearing Guarantees. In the first quarter of 2020, FICC’s sponsored clearing model was updated such that the Firm could be responsible for liquidation of a sponsored member’s account and guarantees any resulting loss to the FICC in the event the sponsored member fails to fully pay any net liquidation amount due from the sponsored member to the FICC. Accordingly, the Firm’s maximum potential payout amount as of September 30, 2020 reflects the total of the estimated net liquidation amounts for sponsored member accounts. For more information on the nature of the obligations and related business activities for our guarantees, see Note 13 to the financial statements in the 2019 Form 10-K . Other Guarantees and Indemnities In the normal course of business, the Firm provides guarantees and indemnifications in a variety of transactions. These provisions generally are standard contractual terms. Certain of these guarantees and indemnifications related to indemnities, exchange and clearinghouse member guarantees and merger and acquisition guarantees are described in Note 13 to the financial statements in the 2019 Form 10-K . In addition, in the ordinary course of business, the Firm guarantees the debt and/or certain trading obligations (including obligations associated with derivatives, foreign exchange contracts and the settlement of physical commodities) of certain subsidiaries. These guarantees generally are entity or product specific and are required by investors or trading counterparties. The activities of the Firm’s subsidiaries covered by these guarantees (including any related debt or trading obligations) are included in the financial statements. Finance Subsidiary The Parent Company fully and unconditionally guarantees the securities issued by Morgan Stanley Finance LLC, a wholly owned finance subsidiary. Contingencies Legal In addition to the matters described in the following paragraphs, in the normal course of business, the Firm has been named, from time to time, as a defendant in various legal actions, including arbitrations, class actions and other litigation, arising in connection with its activities as a global diversified financial services institution. Certain of the actual or threatened legal actions include claims for substantial compensatory and/or punitive damages or claims for indeterminate amounts of damages. In some cases, the entities that would otherwise be the primary defendants in such cases are bankrupt or are in financial distress. These actions have included, but are not limited to, residential mortgage and credit crisis-related matters. While the Firm has identified below any individual proceedings where the Firm believes a material loss to be reasonably possible and reasonably estimable, there can be no assurance that material losses will not be incurred from claims that have not yet been asserted or are not yet determined to be probable or possible and reasonably estimable losses. The Firm contests liability and/or the amount of damages as appropriate in each pending matter. Where available information indicates that it is probable a liability had been incurred at the date of the financial statements and the Firm can reasonably estimate the amount of that loss, the Firm accrues the estimated loss by a charge to income. In many proceedings and investigations, however, it is inherently difficult to determine whether any loss is probable or even possible or to estimate the amount of any loss. In addition, even where a loss is possible or an exposure to loss exists in excess of the liability already accrued with respect to a previously recognized loss contingency, it is not always possible to reasonably estimate the size of the possible loss or range of loss. For certain legal proceedings and investigations, the Firm cannot reasonably estimate such losses, particularly for proceedings and investigations where the factual record is being developed or contested or where plaintiffs or government entities seek substantial or indeterminate damages, restitution, disgorgement or penalties. Numerous issues may need to be resolved, including through potentially lengthy discovery and determination of important factual matters, determination of issues related to class certification and the calculation of damages or other relief, and by addressing novel or unsettled legal questions relevant to the proceedings or investigations in question, before a loss or additional loss or range of loss or additional range of loss can be reasonably estimated for a proceeding or investigation. For certain other legal proceedings and investigations, the Firm can estimate reasonably possible losses, additional losses, ranges of loss or ranges of additional loss in excess of amounts accrued but does not believe, based on current knowledge and after consultation with counsel, that such losses will have a material adverse effect on the Firm’s financial statements as a whole, other than the matters referred to in the following paragraphs. On July 15, 2010 , China Development Industrial Bank (“CDIB”) filed a complaint against the Firm, styled China Development Industrial Bank v. Morgan Stanley & Co. Incorporated et al. , which is pending in the Supreme Court of the State of New York, New York County (“Supreme Court of NY”). The complaint relates to a $275 million CDS referencing the super senior portion of the STACK 2006-1 CDO. The complaint asserts claims for common law fraud, fraudulent inducement and fraudulent concealment and alleges that the Firm misrepresented the risks of the STACK 2006-1 CDO to CDIB, and that the Firm knew that the assets backing the CDO were of poor quality when it entered into the CDS with CDIB. The complaint seeks compensatory damages related to the approximately $228 million that CDIB alleges it has already lost under the CDS, rescission of CDIB’s obligation to pay an additional $12 million , punitive damages, equitable relief, fees and costs. On February 28, 2011, the court denied the Firm’s motion to dismiss the complaint. On December 21, 2018, the court denied the Firm’s motion for summary judgment and granted in part the Firm’s motion for sanctions relating to spoliation of evidence. On January 24, 2019, CDIB filed a notice of appeal from the court’s December 21, 2018 order, and on January 25, 2019, the Firm filed a notice of appeal from the same order. On March 7, 2019, the court denied the relief that CDIB sought in a motion to clarify and resettle the portion of the court’s December 21, 2018 order granting spoliation sanctions. On May 21, 2020, the Appellate Division, First Department (“First Department”), modified the Supreme Court of NY’s order to deny the Firm’s motion for sanctions relating to spoliation of evidence and otherwise affirmed the denial of the Firm’s motion for summary judgment. On June 19, 2020, the Firm moved for leave to appeal the First Department’s decision to the New York Court of Appeals (“Court of Appeals”), which the First Department denied on July 24, 2020. Based on currently available information, the Firm believes it could incur a loss in this action of up to approximately $240 million plus pre- and post-judgment interest, fees and costs. On September 23, 2014, Financial Guaranty Insurance Company (“FGIC”) filed a complaint against the Firm in the Supreme Court of NY styled Financial Guaranty Insurance Company v. Morgan Stanley ABS Capital I Inc. et al. relating to the Morgan Stanley ABS Capital I Inc. Trust 2007-NC4. The complaint asserts claims for breach of contract and fraudulent inducement and alleges, among other things, that the loans in the trust breached various representations and warranties and defendants made untrue statements and material omissions to induce FGIC to issue a financial guaranty policy on certain classes of certificates that had an original balance of approximately $876 million . The complaint seeks, among other relief, specific performance of the loan breach remedy procedures in the transaction documents, compensatory, consequential and punitive damages, attorneys’ fees and interest. On January 23, 2017, the court denied the Firm’s motion to dismiss the complaint. On September 13, 2018, the First Department affirmed in part and reversed in part the lower court’s order denying the Firm’s motion to dismiss. On December 20, 2018, the First Department denied plaintiff’s motion for leave to appeal its decision to the Court of Appeals or, in the alternative, for re-argument. Based on currently available information, the Firm believes that it could incur a loss in this action of up to approximately $277 million , the total original unpaid balance of the mortgage loans for which the Firm received repurchase demands from a certificate holder and FGIC that the Firm did not repurchase, plus pre- and post- judgment interest, fees and costs, as well as claim payments that FGIC has made and will make in the future. In addition, plaintiff is seeking to expand the number of loans at issue and the possible range of loss could increase. On January 23, 2015, Deutsche Bank National Trust Company, in its capacity as trustee, filed a complaint against the Firm styled Deutsche Bank National Trust Company solely in its capacity as Trustee of the Morgan Stanley ABS Capital I Inc. Trust 2007-NC4 v. Morgan Stanley Mortgage Capital Holdings LLC as Successor-by-Merger to Morgan Stanley Mortgage Capital Inc., and Morgan Stanley ABS Capital I Inc. , pending in the Supreme Court of NY. The complaint asserts claims for breach of contract and alleges, among other things, that the loans in the trust, which had an original principal balance of approximately $1.05 billion , breached various representations and warranties. The complaint seeks, among other relief, specific performance of the loan breach remedy procedures in the transaction documents, compensatory, consequential, rescissory, equitable and punitive damages, attorneys’ fees, costs and other related expenses, and interest. On December 11, 2015, the court granted in part and denied in part the Firm’s motion to dismiss the complaint. On October 19, 2018, the court granted the Firm’s motion for leave to amend its answer and to stay the case pending resolution of Deutsche Bank National Trust Company’s appeal to the Court of Appeals in another case, styled Deutsche Bank National Trust Company v. Barclays Bank PLC , regarding the applicable statute of limitations. On January 17, 2019, the First Department reversed the trial court’s order to the extent that it had granted in part the Firm’s motion to dismiss the complaint. On June 4, 2019, the First Department granted the Firm’s motion for leave to appeal to the Court of Appeals. On March 19, 2020, the Firm filed a motion for partial summary judgment. Based on currently available information, the Firm believes that it could incur a loss in this action of up to approximately $277 million , the total original unpaid balance of the mortgage loans for which the Firm received repurchase demands from a certificate holder and a monoline insurer that the Firm did not repurchase, plus pre- and post-judgment interest, fees and costs, but plaintiff is seeking to expand the number of loans at issue and the possible range of loss could increase. Tax In matters styled Case number 15/3637 and Case number 15/4353 , the Dutch Tax Authority (“Dutch Authority”) is challenging in the Dutch courts, the prior set-off by the Firm of approximately €124 million (approximately $145 million ) plus accrued interest of withholding tax credits against the Firm’s corporation tax liabilities for the tax years 2007 to 2013. The Dutch Authority alleges that the Firm was not entitled to receive the withholding tax credits on the basis, inter alia, that a Firm subsidiary did not hold legal title to certain securities subject to withholding tax on the relevant dates. The Dutch Authority has also alleged that the Firm failed to provide certain information to the Dutch Authority and keep adequate books and records. On April 26, 2018, the District Court in Amsterdam issued a decision dismissing the Dutch Authority’s claims with respect to certain of the tax years in dispute. On May 12, 2020, the Court of Appeal in Amsterdam granted the Dutch Authority’s appeal in matters re-styled Case number 18/00318 and Case number 18/00319

Generally, most assets owned by consolidated VIEs cannot be removed unilaterally by the Firm and are not available to the Firm while the related liabilities issued by consolidated VIEs are non-recourse to the Firm. However, in certain consolidated VIEs, the Firm either has the unilateral right to remove assets or provides additional recourse through derivatives such as total return swaps, guarantees or other forms of involvement. In general, the Firm’s exposure to loss in consolidated VIEs is limited to losses that would be absorbed on the VIE net assets recognized in its financial statements, net of amounts absorbed by third-party variable interest holders.

Where notional amounts are utilized in quantifying the maximum exposure related to derivatives, such amounts do not reflect changes in fair value recorded by the Firm. 4. Additional VIE assets owned represents the carrying value of total exposure to non-consolidated VIEs for which the maximum exposure to loss is less than specific thresholds, primarily interests issued by securitization SPEs. The Firm’s maximum exposure to loss generally equals the fair value of the assets owned. These assets are primarily included in Trading assets and Investment securities and are measured at fair value (see Note 5 ). The Firm does not provide additional support in these transactions through contractual facilities, guarantees or similar derivatives. The majority of the VIEs included in the previous tables are sponsored by unrelated parties; examples of the Firm’s involvement with these VIEs include its secondary market-making activities and the securities held in its Investment securities portfolio (see Note 8 ). The Firm’s maximum exposure to loss is dependent on the nature of the Firm’s variable interest in the VIE and is limited to the notional amounts of certain liquidity facilities and other credit support, total return swaps and written put options, as well as the fair value of certain other derivatives and investments the Firm has made in the VIE. The Firm’s maximum exposure to loss in the previous tables does not include the offsetting benefit of hedges or any reductions associated with the amount of collateral held as part of a transaction with the VIE or any party to the VIE directly against a specific exposure to loss. Liabilities issued by VIEs generally are non-recourse to the Firm.

Amounts include CLO transactions managed by unrelated third parties. 2. Amounts include assets transferred by unrelated transferors. The previous tables include transactions with SPEs in which the Firm, acting as principal, transferred financial assets with continuing involvement and received sales treatment. The transferred assets are carried at fair value prior to securitization, and any changes in fair value are recognized in the income statements. The Firm may act as underwriter of the beneficial interests issued by these securitization vehicles, for which Investment banking revenues are recognized. The Firm may retain interests in the securitized financial assets as one or more tranches of the securitization. These retained interests are generally carried at fair value in the balance sheets with changes in fair value recognized in the income statements. Fair value for these interests is measured using techniques that are consistent with the valuation techniques applied to the Firm’s major categories of assets and liabilities as described in Note 2 in the 2019 Form 10-K and Note 5 herein. Further, as permitted by applicable guidance, certain transfers of assets where the Firm’s only continuing involvement is a derivative are only reported in the following Assets Sold with Retained Exposure table.

Brokers and Dealers [Abstract]
Regulatory Requirements	Regulatory Requirements Regulatory Capital Framework and Requirements For a discussion of the Firm’s regulatory capital framework, see Note 15 to the financial statements in the 2019 Form 10-K . The Firm is required to maintain minimum risk-based and leverage-based capital ratios under regulatory capital requirements. A summary of the calculations of regulatory capital and RWA follows. Minimum risk-based capital ratio requirements apply to Common Equity Tier 1 capital, Tier 1 capital and Total capital (which includes Tier 2 capital). Capital standards require certain adjustments to, and deductions from, capital for purposes of determining these ratios. At September 30, 2020 and December 31, 2019 , the Firm’s ratios for determining regulatory compliance are based on the Advanced Approach and the Standardized Approach rules, respectively. In the current year period, the U.S. banking agencies have adopted an interim final rule altering, for purposes of the regulatory capital rules, the required adoption time period for CECL. As of September 30, 2020 , the risk-based and leverage-based capital amounts and ratios, as well as RWA, adjusted average assets and supplementary leverage exposure are calculated excluding the effect of the adoption of CECL based on our election to defer this effect over a five-year transition period in accordance with the interim final rule. In addition to the minimum risk-based capital ratio requirements, the Firm is subject to the following Common Equity Tier 1 buffers: • A greater than 2.5% capital conservation buffer; • The G-SIB capital surcharge, currently at 3% ; and • Up to a 2.5% CCyB, currently set by U.S. banking agencies at zero . The Firm’s Regulatory Capital and Capital Ratios At September 30, 2020 $ in millions Required Ratio 1 Amount Ratio Risk-based capital Common Equity Tier 1 capital 10.0 % $ 71,157 16.9 % Tier 1 capital 11.5 % 79,905 19.0 % Total capital 13.5 % 89,763 21.4 % Total RWA 420,081 $ in millions Required Ratio 1 At Leverage-based capital Adjusted average assets 2 $ 962,435 Tier 1 leverage ratio 4.0 % 8.3 % Supplementary leverage exposure 3,4 $ 1,084,348 SLR 3 5.0 % 7.4 % At December 31, 2019 $ in millions Required Ratio 1 Amount Ratio Risk-based capital Common Equity Tier 1 capital 10.0 % $ 64,751 16.4 % Tier 1 capital 11.5 % 73,443 18.6 % Total capital 13.5 % 82,708 21.0 % Total RWA 394,177 $ in millions Required Ratio 1 At Leverage-based capital Adjusted average assets 2 $ 889,195 Tier 1 leverage ratio 4.0 % 8.3 % Supplementary leverage exposure 3,4 $ 1,155,177 SLR 3 5.0 % 6.4 % 1. Required ratios are inclusive of any buffers applicable as of the date presented. Failure to maintain the buffers would result in restrictions on the Firm’s ability to make capital distributions, including the payment of dividends and the repurchase of stock, and to pay discretionary bonuses to executive officers. 2. Adjusted average assets represents the denominator of the Tier 1 leverage ratio and is composed of the average daily balance of consolidated on-balance sheet assets for the quarters ending on the respective balance sheet dates, reduced by disallowed goodwill, intangible assets, investments in covered funds, defined benefit pension plan assets, after-tax gain on sale from assets sold into securitizations, investments in the Firm’s own capital instruments, certain defined tax assets and other capital deductions. 3. Based on a Federal Reserve interim final rule in effect until March 31, 2021, the Firm’s SLR and Supplementary leverage exposure as of September 30, 2020 reflect the exclusion of U.S. Treasury securities and deposits at Federal Reserve Banks. 4. Supplementary leverage exposure is the sum of Adjusted average assets used in the Tier 1 leverage ratio and other adjustments, primarily: (i) for derivatives, potential future exposure and the effective notional principal amount of sold credit protection offset by qualifying purchased credit protection; (ii) the counterparty credit risk for repo-style transactions; and (iii) the credit equivalent amount for off-balance sheet exposures. U.S. Bank Subsidiaries’ Regulatory Capital and Capital Ratios The OCC establishes capital requirements for the Firm’s U.S. bank subsidiaries, which as of September 30, 2020 include Morgan Stanley Bank, N.A. (“MSBNA”) and Morgan Stanley Private Bank, National Association (“MSPBNA”) (collectively, the “U.S. Bank Subsidiaries”), and evaluates their compliance with such capital requirements. Regulatory capital requirements for the U.S. Bank Subsidiaries are calculated in a similar manner to the Firm’s regulatory capital requirements, although G-SIB capital surcharge requirements do not apply to the U.S. Bank Subsidiaries. The OCC’s regulatory capital framework includes Prompt Corrective Action (“PCA”) standards, including “well-capitalized” PCA standards that are based on specified regulatory capital ratio minimums. For the Firm to remain an FHC, the U.S. Bank Subsidiaries must remain well-capitalized in accordance with the OCC’s PCA standards. In addition, failure by the U.S. Bank Subsidiaries to meet minimum capital requirements may result in certain mandatory and discretionary actions by regulators that, if undertaken, could have a direct material effect on the U.S. Bank Subsidiaries’ and the Firm’s financial statements. At September 30, 2020 and December 31, 2019 , the U.S. Bank Subsidiaries’ risk-based capital ratios are based on the Standardized Approach rules. At September 30, 2020 , the risk-based and leverage-based capital amounts and ratios are calculated excluding the effect of the adoption of CECL based on our election to defer this effect over a five-year transition period.

A portion of common stock repurchases was conducted under a sales plan with MUFG, whereby MUFG sold shares of the Firm’s common stock to the Firm, as part of the Firm’s Share Repurchase Program. The sales plan is only intended to maintain MUFG’s ownership percentage below 24.9% in order to comply with MUFG’s passivity commitments to the Board of Governors of the Federal Reserve System and has no impact on the strategic alliance between MUFG and the Firm, including the joint ventures in Japan.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Firm is under continuous examination by the IRS and other tax authorities in certain countries, such as Japan and the U.K., and in states and localities in which it has significant business operations, such as New York. The Firm believes that the resolution of these tax examinations will not have a material effect on the annual financial statements, although a resolution could have a material impact in the income statements and on the effective tax rate for any period in which such resolutions occur. The Firm has established a liability for unrecognized tax benefits, and associated interest, if applicable (“tax liabilities”), that it believes is adequate in relation to the potential for additional assessments. Once established, the Firm adjusts such tax liabilities only when new information is available or when an event occurs necessitating a change. It is reasonably possible that significant changes in the balance of unrecognized tax benefits may occur within the next 12 months. At this time, however, it is not possible to reasonably estimate the expected change to the total amount of unrecognized tax benefits and the impact on the Firm’s effective tax rate over the next 12 months.

Accounting Policies [Abstract]
Basis of Financial Information	Basis of Financial Information The financial statements are prepared in accordance with U.S. GAAP, which requires the Firm to make estimates and assumptions regarding the valuations of certain financial instruments, the valuations of goodwill and intangible assets, the outcome of legal and tax matters, deferred tax assets, ACL, and other matters that affect its financial statements and related disclosures. The Firm believes that the estimates utilized in the preparation of its financial statements are prudent and reasonable. Actual results could differ materially from these estimates. Certain reclassifications have been made to prior periods to conform to the current presentation. The Notes are an integral part of the Firm's financial statements. The Firm has evaluated subsequent events for adjustment to or disclosure in these financial statements through the date of this report and has not identified any recordable or disclosable events not otherwise reported in these financial statements or the notes thereto. The accompanying financial statements should be read in conjunction with the Firm’s financial statements and notes thereto included in the 2019 Form 10-K . Certain footnote disclosures included in the 2019 Form 10-K have been condensed or omitted from these financial statements as they are not required for interim reporting under U.S. GAAP. The financial statements reflect all adjustments of a normal, recurring nature that are, in the opinion of management, necessary for the fair presentation of the results for the interim period. The results of operations for interim periods are not necessarily indicative of results for the entire year.
Consolidation	Consolidation The financial statements include the accounts of the Firm, its wholly owned subsidiaries and other entities in which the Firm has a controlling financial interest, including certain VIEs (see Note 15 ). Intercompany balances and transactions have been eliminated. For consolidated subsidiaries that are not wholly owned, the third-party holdings of equity interests are referred to as noncontrolling interests. The net income attributable to noncontrolling interests for such subsidiaries is presented as Net income applicable to noncontrolling interests in the income statements. The portion of shareholders’ equity that is attributable to noncontrolling interests for such subsidiaries is presented as noncontrolling interests, a component of Total equity, in the balance sheets. For a discussion of the Firm’s significant regulated U.S. and international subsidiaries and its involvement with VIEs, see Note 1 to the financial statements in the 2019 Form 10-K .
Accounting Updates Adopted in 2020	Accounting Updates Adopted in 2020 Reference Rate Reform The Firm adopted the Reference Rate Reform accounting update in the current year period. There was no impact to the Firm’s financial statements upon initial adoption. This accounting update provides optional accounting relief to entities with contracts, hedge accounting relationships or other transactions that reference LIBOR or other interest rate benchmarks for which the referenced rate is expected to be discontinued or replaced. The Firm is applying the accounting relief as relevant contract and hedge accounting relationship modifications are made during the course of the reference rate reform transition period. The optional relief generally allows for contract modifications solely related to the replacement of the reference rate to be accounted for as a continuation of the existing contract instead of as an extinguishment of the contract, and would therefore not trigger certain accounting impacts that would otherwise be required. It also allows entities to change certain critical terms of existing hedge accounting relationships that are affected by reference rate reform, and these changes would not require de-designating the hedge accounting relationship. The optional relief ends December 31, 2022. Financial Instruments—Credit Losses The Firm adopted the Financial Instruments — Credit Losses accounting update on January 1, 2020. This accounting update impacted the impairment model for certain financial assets measured at amortized cost by requiring a CECL methodology to estimate expected credit losses over the entire life of the financial asset, recorded at inception or purchase. CECL replaced the loss model previously applicable to loans held for investment, HTM securities and other receivables carried at amortized cost, such as employee loans. The update also eliminated the concept of other-than-temporary impairment for AFS securities and instead requires impairments on AFS securities to be recognized in earnings through an allowance when the fair value is less than amortized cost and a credit loss exists, and through a permanent reduction of the amortized cost basis when the securities are expected to be sold before recovery of amortized cost. For certain portfolios, we determined that there are de minimus or zero expected credit losses, for example, for lending and financing transactions, such as Securities borrowed, Securities purchased under agreements to resell and certain other portfolios where collateral arrangements are being followed. Also, we have zero expected credit losses for certain financial assets based on the credit quality of the borrower or issuer, such as U.S. government and agency securities. At transition on January 1, 2020, the adoption of this accounting standard resulted in an increase in the allowance for credit losses of $131 million with a corresponding reduction in Retained earnings of $100 million , net of tax. The adoption impact was primarily attributable to a $124 million increase in the allowance for credit losses on employee loans. The following discussion highlights changes to the Firm’s accounting policies as a result of this adoption. Instruments Measured at Amortized Cost and Certain Off-Balance Sheet Credit Exposures Allowance for Credit Losses The ACL for financial instruments measured at amortized cost and certain off-balance sheet exposures ( e.g., HFI loans and lending commitments, HTM securities, customer and other receivables and certain guarantees) represents an estimate of expected credit losses over the entire life of the financial instrument. Factors considered by management when determining the ACL include payment status, fair value of collateral, expected payments of principal and interest, as well as internal or external information relating to past events, current conditions and reasonable and supportable forecasts. The Firm’s three forecasts include assumptions about certain macroeconomic variables including, but not limited to, U.S. gross domestic product, equity market indices, unemployment rates, as well as commercial real estate and home price indices. At the conclusion of the Firm’s reasonable and supportable forecast period of 13 quarters, there is a gradual reversion back to historical averages. The ACL is measured on a collective basis when similar risk characteristics exist for multiple instruments considering all available information relevant to assessing the collectability of cash flows. Generally, the Firm applies a probability of default/loss given default model for instruments that are collectively assessed, under which the ACL is calculated as the product of probability of default, loss given default and exposure at default. These parameters are forecast for each collective group of assets using a scenario-based statistical model and at the conclusion of the Firm’s reasonable and supportable forecast period, the parameters gradually revert back to historical averages. If the instrument does not share similar risk characteristics with other instruments, including when it is probable that the Firm will be unable to collect the full payment of principal and interest on the instrument when due, the ACL is measured on an individual basis. The Firm generally applies a discounted cash flow method for instruments that are individually assessed. The Firm may also elect to use an approach that considers the fair value of the collateral when measuring the ACL if the loan is collateral dependent ( i.e., repayment of the loan is expected to be provided substantially by the sale or operation of the underlying collateral and the borrower is experiencing financial difficulty). Additionally, the Firm can elect to use an approach to measure the ACL using the fair value of collateral where the borrower is required to, and reasonably expected to, continually adjust and replenish the amount of collateral securing the instrument to reflect changes in the fair value of such collateral. The Firm has elected to use this approach for certain securities-based loans, customer receivables representing margin loans, Securities purchased under agreements to resell and Securities borrowed. Credit quality indicators considered in developing the ACL include: • Corporate loans, Secured lending facilities, Commercial real estate loans and securities, and Other loans: Internal risk ratings developed by the Credit Risk Management Department which are refreshed at least annually, and more frequently as necessary. These ratings generally correspond to external ratings published by S&P. The Firm also considers transaction structure, including type of collateral, collateral terms, and position of the obligation within the capital structure. In addition, for Commercial real estate, the Firm considers property type and location, net operating income, LTV ratios, among others, as well as commercial real estate price and credit spread indices and capitalization rates. • Residential real estate loans: Loan origination Fair Isaac Corporation (“FICO”) credit scores as determined by independent credit agencies in the United States and loan-to-value (“LTV”) ratios. • Employee loans: Employment status, which includes those currently employed by the Firm and for which the Firm can deduct any unpaid amounts due to it through certain compensation arrangements; and those no longer employed by the Firm where such compensation arrangements are no longer applicable. For Securities-based loans, the Firm generally measures the ACL based on the fair value of collateral. Qualitative and environmental factors such as economic and business conditions, the nature and volume of the portfolio, and lending terms and the volume and severity of past due loans are also considered in the ACL calculations. Presentation of ACL and Provision for Credit Losses ACL Provision for credit losses Instruments measured at amortized cost ( e.g., HFI loans, HTM securities and customer and other receivables) Contra asset Other revenue Employee loans Contra asset Compensation and benefits expense Off-balance sheet instruments ( e.g., HFI lending commitments and certain guarantees) Other liabilities and accrued expenses Other expense Troubled Debt Restructurings (“TDRs”) The Firm may modify the terms of certain loans for economic or legal reasons related to a borrower’s financial difficulties by granting one or more concessions that the Firm would not otherwise consider. Such modifications are accounted for and reported as a TDR, except for certain modifications related to the Coronavirus Disease (“COVID-19”) as noted in “Modifications and Nonaccrual Status for Borrowers Impacted by COVID-19” herein. A loan that has been modified in a TDR is generally considered to be impaired and is evaluated individually. TDRs are also generally classified as nonaccrual and may be returned to accrual status only after the Firm expects repayment of the remaining contractual principal and interest and there is sustained repayment performance for a reasonable period. Nonaccrual The Firm places financial instruments on nonaccrual status if principal or interest is past due for a period of 90 days or more or payment of principal or interest is in doubt unless the obligation is well-secured and in the process of collection, or in certain cases when related to COVID-19 as noted in “Modifications and Nonaccrual Status for Borrowers Impacted by COVID-19” herein. For any instrument placed on nonaccrual status, the Firm reverses any unpaid interest accrued with an offsetting reduction to Interest income. Principal and interest payments received on nonaccrual instruments are applied to principal if there is doubt regarding the ultimate collectability of principal. If collection of the principal is not in doubt, interest income is realized on a cash basis. If neither principal nor interest collection is in doubt and the instruments are brought current, instruments are generally placed on accrual status and interest income is recognized using the effective interest method. Modifications and Nonaccrual Status for Borrowers Impacted by COVID-19 In the first quarter of 2020, the Firm elected to apply the guidance issued by Congress in the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) as well as by the U.S. banking agencies stating that certain concessions granted to borrowers that are current on existing loans, either individually or as part of a program for creditworthy borrowers who are experiencing short-term financial or operational problems as a result of COVID-19, generally would not be considered TDRs. Additionally, these loans generally would not be considered nonaccrual status unless collectability concerns exist despite the modification provided. For loans remaining on accrual status, the Firm elected to continue recognizing interest income during the modification periods. ACL Write-offs The Firm writes-off a financial instrument in the period that it is deemed uncollectible and records a reduction in the ACL and the balance of the financial instrument in the balance sheet. However, for accrued interest receivable balances that are separately recorded from the related financial instruments, the Firm's nonaccrual policy requires that accrued interest receivable be written off against Interest income when the related financial instrument is placed in nonaccrual status. Accordingly, the Firm elected not to measure an ACL for accrued interest receivables. However, in the case of loans which are modified as a result of COVID-19 and remain on accrual status due to the relief noted in “Modifications and Nonaccrual Status for Borrowers Impacted by COVID-19,” accrued interest receivable balances are assessed for any required ACL. Available-for-Sale (“AFS”) Investment Securities AFS securities are reported at fair value in the balance sheets. Interest income, including amortization of premiums and accretion of discounts, is included in Interest income in the Income statements. Unrealized gains are recorded in OCI and unrealized losses are recorded either in OCI or in Other revenues as described below. AFS securities in an unrealized loss position are first evaluated to determine whether there is an intent to sell or it is more likely than not the Firm will be required to sell before recovery of the amortized cost basis. If so, the entire unrealized loss is recognized in Other revenues, as any previously established ACL is written off and the amortized cost basis is written down to the fair value of the security. For all other AFS securities in an unrealized loss position, any portion of unrealized losses representing a credit loss is recognized in Other revenues and as an increase to the ACL for AFS securities, with the remainder of unrealized losses recognized in OCI. When considering whether a credit loss exists, relevant information as discussed in Note 2 of the 2019 Form 10-K is considered, except that with the adoption of Financial Instruments—Credit Losses in 2020 , the length of time the fair value has been less than the amortized cost basis is no longer considered. Presentation of ACL and Provision for Credit Losses ACL Provision for credit losses AFS securities Contra Investment securities Other revenue Nonaccrual & ACL Write-Offs on AFS Securities AFS securities follow the same nonaccrual and write-off guidance as discussed in “Instruments Measured at Amortized Cost and Certain Off-Balance Sheet Credit Exposures” herein, except as set forth in “Modifications and Nonaccrual Status for Borrowers Impacted by COVID-19.”
Goodwill	Goodwill The Firm completed its annual goodwill impairment testing as of July 1, 2020. The Firm’s impairment testing did not indicate any goodwill impairment, as each of the Firm’s reporting units with goodwill had a fair value that was in excess of its carrying value.

The loans were transferred into Level 3 in the first quarter as the significance of the margin loan rate input increased as a result of reduced liquidity, and transferred out of Level 3 in the second quarter as liquidity conditions improved reducing the significance of the input.

Net transfers in the current year period reflect the largely offsetting impacts of transfers in of $857 million of equity margin loans and transfers out of $707 million of equity margin loans. The loans were transferred into Level 3 in the first quarter as the significance of the margin loan rate input increased as a result of reduced liquidity, and transferred out of Level 3 in the second quarter as liquidity conditions improved reducing the significance of the input.

Gains and losses for Loans and Other assets—Other investments are classified in Other revenues. For other items, gains and losses are recorded in Other revenues if the item is held for sale; otherwise, they are recorded in Other expenses. 2. Nonrecurring changes in the fair value of loans and lending commitments were calculated as follows: for the held-for-investment category, based on the value of the underlying collateral; and for the held-for-sale category, based on recently executed transactions, market price quotations, valuation models that incorporate market observable inputs where possible, such as comparable loan or debt prices and CDS spread levels adjusted for any basis difference between cash and derivative instruments, or default recovery analysis where such transactions and quotations are unobservable. 3. Losses related to Other assets—Other investments were determined using techniques that included discounted cash flow models, methodologies that incorporate multiples of certain comparable companies and recently executed transactions. 4. Losses related to Other assets—Premises, equipment and software generally include impairments as well as write-offs related to the disposal of certain assets.

Failure to maintain the buffers would result in restrictions on the Firm’s ability to make capital distributions, including the payment of dividends and the repurchase of stock, and to pay discretionary bonuses to executive officers. 2. Adjusted average assets represents the denominator of the Tier 1 leverage ratio and is composed of the average daily balance of consolidated on-balance sheet assets for the quarters ending on the respective balance sheet dates, reduced by disallowed goodwill, intangible assets, investments in covered funds, defined benefit pension plan assets, after-tax gain on sale from assets sold into securitizations, investments in the Firm’s own capital instruments, certain defined tax assets and other capital deductions. 3. Based on a Federal Reserve interim final rule in effect until March 31, 2021, the Firm’s SLR and Supplementary leverage exposure as of September 30, 2020 reflect the exclusion of U.S. Treasury securities and deposits at Federal Reserve Banks. 4. Supplementary leverage exposure is the sum of Adjusted average assets used in the Tier 1 leverage ratio and other adjustments, primarily: (i) for derivatives, potential future exposure and the effective notional principal amount of sold credit protection offset by qualifying purchased credit protection; (ii) the counterparty credit risk for repo-style transactions; and (iii) the credit equivalent amount for off-balance sheet exposures.
