Use of Estimates Preparation of these consolidated financial statements requires management to make certain estimates and assumptions, the most important of which relate to fair value measurements, accounting for goodwill and identifiable intangible assets, discretionary compensation accruals, the allowance for credit losses on loans receivable and lending commitments held for investment, provisions for losses that may arise from litigation and regulatory proceedings (including governmental investigations), and provisions for losses that may arise from tax audits. These estimates and assumptions are based on the best available information but actual results could be materially different. Revenue Recognition Financial Assets and Financial Liabilities at Fair Value. Revenue from Contracts with Clients. 2014-09, Revenues from contracts with clients subject to this ASU represent approximately 45% of total non-interest revenues for each of the three and six months ended June 2019 Investment Banking Advisory. Non-refundable Expenses associated with financial advisory assignments are recognized when incurred and are included in other expenses. Client reimbursements for such expenses are included in investment banking revenues. Underwriting. Expenses associated with underwriting assignments are generally deferred until the related revenue is recognized or the assignment is otherwise concluded. Such expenses are included in other expenses. Investment Management The firm earns management fees and incentive fees for investment management services, which are included in investment management revenues. The firm makes payments to brokers and advisors related to the placement of the firm’s investment funds (distribution fees), which are included in brokerage, clearing, exchange and distribution fees. Management Fees. month-end Distribution fees paid by the firm are calculated based on either a percentage of the management fee, the investment fund’s net asset value or the committed capital. Such fees are included in brokerage, clearing, exchange and distribution fees. Incentive Fees. Incentive fees earned from a fund or separately managed account are recognized when it is probable that a significant reversal of such fees will not occur, which is generally when such fees are no longer subject to fluctuations in the market value of investments held by the fund or separately managed account. Therefore, incentive fees recognized during the period may relate to performance obligations satisfied in previous periods. Commissions and Fees The firm earns commissions and fees from executing and clearing client transactions on stock, options and futures markets, as well as over-the-counter Remaining Performance Obligations Remaining performance obligations are services that the firm has committed to perform in the future in connection with its contracts with clients. The firm’s remaining performance obligations are generally related to its financial advisory assignments and certain investment management activities. Revenues associated with remaining performance obligations relating to financial advisory assignments cannot be determined until the outcome of the transaction. For the firm’s investment management activities, where fees are calculated based on the net asset value of the fund or separately managed account, future revenues associated with such remaining performance obligations cannot be determined as such fees are subject to fluctuations in the market value of investments held by the fund or separately managed account. The firm is able to determine the future revenues associated with management fees calculated based on committed capital. As of June 2019, substantially all future net revenues associated with such remaining performance obligations will be recognized through 2024. Annual revenues associated with such performance obligations average less than $250 million through 2024. Transfers of Financial Assets Transfers of financial assets are accounted for as sales when the firm has relinquished control over the assets transferred. For transfers of financial assets accounted for as sales, any gains or losses are recognized in net revenues. Assets or liabilities that arise from the firm’s continuing involvement with transferred financial assets are initially recognized at fair value. For transfers of financial assets that are not accounted for as sales, the assets are generally included in financial instruments owned and the transfer is accounted for as a collateralized financing, with the related interest expense recognized over the life of the transaction. See Note 10 for further information about transfers of financial assets accounted for as collateralized financings and Note 11 for further information about transfers of financial assets accounted for as sales. Cash and Cash Equivalents The firm defines cash equivalents as highly liquid overnight deposits held in the ordinary course of business. Cash and cash equivalents included cash and due from banks of $12.29 billion as of June 2019 and $10.66 billion as of December 2018. Cash and cash equivalents also included interest-bearing deposits with banks of $78.80 billion as of June 2019 and $119.89 billion as of December 2018. The firm segregates cash for regulatory and other purposes related to client activity. Cash and cash equivalents segregated for regulatory and other purposes were $23.14 billion as of both June 2019 and December 2018. In addition, the firm segregates securities for regulatory and other purposes related to client activity. See Note 10 for further information about segregated securities. Customer and Other Receivables Customer and other receivables included receivables from customers and counterparties of $56.59 billion as of June 2019 and $53.81 billion as of December 2018, and receivables from brokers, dealers and clearing organizations of $27.33 billion as of June 2019 and $25.50 billion as of December 2018. Such receivables primarily consist of customer margin loans, receivables resulting from unsettled transactions, collateral posted in connection with certain derivative transactions and certain transfers of assets accounted for as secured loans rather than purchases at fair value. Substantially all of these receivables are accounted for at amortized cost net of estimated uncollectible amounts. Certain of the firm’s customer and other receivables are accounted for at fair value under the fair value option, with changes in fair value generally included in market making revenues. See Note 8 for further information about customer and other receivables accounted for at fair value under the fair value option. In addition, the firm’s customer and other receivables included $3.34 billion as of June 2019 and $3.83 billion as of December 2018 of loans held for sale accounted for at the lower of cost or fair value. See Note 5 for an overview of the firm’s fair value measurement policies. As of both June 2019 and December 2018, the carrying value of receivables not accounted for at fair value generally approximated fair value. As these receivables are not accounted for at fair value, they are not included in the firm’s fair value hierarchy in Notes 5 through 8. Had these receivables been included in the firm’s fair value hierarchy, substantially all would have been classified in level 2 as of both June 2019 and December 2018. Interest on customer and other receivables is recognized over the life of the transaction and included in interest income. Customer and other receivables includes receivables from contracts with clients and contract assets. Contract assets represent the firm’s right to receive consideration for services provided in connection with its contracts with clients for which collection is conditional and not merely subject to the passage of time. The firm’s receivables from contracts with clients were $2.34 billion as of June 2019 and $1.94 billion as of December 2018. As of both June 2019 and December 2018 contract assets were not material. Customer and Other Payables Customer and other payables included payables to customers and counterparties of $177.18 billion as of June 2019 and $173.99 billion as of December 2018, and payables to brokers, dealers and clearing organizations of $8.10 billion as of June 2019 and $6.24 billion as of December 2018. Such payables primarily consist of customer credit balances related to the firm’s prime brokerage activities. Customer and other payables are accounted for at cost plus accrued interest, which generally approximates fair value. As these payables are not accounted for at fair value, they are not included in the firm’s fair value hierarchy in Notes 5 through 8. Had these payables been included in the firm’s fair value hierarchy, substantially all would have been classified in level 2 as of both June 2019 and December 2018. Interest on customer and other payables is recognized over the life of the transaction and included in interest expense. Offsetting Assets and Liabilities To reduce credit exposures on derivatives and securities financing transactions, the firm may enter into master netting agreements or similar arrangements (collectively, netting agreements) with counterparties that permit it to offset receivables and payables with such counterparties. A netting agreement is a contract with a counterparty that permits net settlement of multiple transactions with that counterparty, including upon the exercise of termination rights by a non-defaulting non-defaulting Derivatives are reported on a net-by-counterparty net-by-counterparty In the consolidated statements of financial condition, derivatives are reported net of cash collateral received and posted under enforceable credit support agreements, when transacted under an enforceable netting agreement. In the consolidated statements of financial condition, resale and repurchase agreements, and securities borrowed and loaned, are not reported net of the related cash and securities received or posted as collateral. See Note 10 for further information about collateral received and pledged, including rights to deliver or repledge collateral. See Notes 7 and 10 for further information about offsetting assets and liabilities. Share-based Compensation The cost of employee services received in exchange for a share-based award is generally measured based on the grant-date fair value of the award. Share-based awards that do not require future service (i.e., vested awards, including awards granted to retirement-eligible employees) are expensed immediately. Share-based awards that require future service are amortized over the relevant service period. Forfeitures are recorded when they occur. Cash dividend equivalents paid on outstanding restricted stock units (RSUs) are charged to retained earnings. If RSUs that require future service are forfeited, the related dividend equivalents originally charged to retained earnings are reclassified to compensation expense in the period in which forfeiture occurs. The firm generally issues new shares of common stock upon delivery of share-based awards. In certain cases, primarily related to conflicted employment (as outlined in the applicable award agreements), the firm may cash settle share-based compensation awards accounted for as equity instruments. For these awards, whose terms allow for cash settlement, additional paid-in Foreign Currency Translation Assets and liabilities denominated in non-U.S. non-U.S. Recent Accounting Developments Revenue from Contracts with Customers (ASC 606). 2014-09. The firm adopted this ASU in January 2018 under a modified retrospective approach. As a result of adopting this ASU, the firm, among other things, delays recognition of non-refundable The firm also prospectively changed the presentation of certain costs from a net presentation within revenues to a gross basis, and vice versa. Beginning in 2018, certain underwriting expenses, which were netted against investment banking revenues, and certain distribution fees, which were netted against investment management revenues, are presented gross as operating expenses. Costs incurred in connection with certain soft-dollar arrangements, which were presented gross as operating expenses, are presented net within commissions and fees. The cumulative effect of adopting this ASU as of January 1, 2018 was a decrease to retained earnings of $53 million (net of tax). Leases (ASC 842). 2016-02, right-of-use right-of-use The firm adopted this ASU in January 2019 under a modified retrospective approach. Upon adoption, in accordance with the ASU, the firm elected to not reassess the lease classification or initial direct costs of existing leases, and to not reassess whether existing contracts contain a lease. In addition, the firm has elected to account for each contract’s lease and non-lease Measurement of Credit Losses on Financial Instruments (ASC 326). 2016-13, Under CECL, the allowance for losses for financial assets that are measured at amortized cost reflects management’s estimate of credit losses over the remaining expected life of such assets. Expected credit losses for newly recognized financial assets, as well as changes to expected credit losses during the period, would be recognized in earnings. For certain purchased financial assets with deterioration in credit quality since origination, an initial allowance would be recorded for expected credit losses and recognized as an increase to the purchase price rather than as an expense. The ASU eliminates the existing accounting guidance for Purchased Credit Impaired (PCI) loans. The ASU is effective for the firm in January 2020 under a modified retrospective approach with early adoption permitted. The firm plans to adopt this ASU on January 1, 2020. Expected credit losses, including losses on off-balance-sheet exposures, such as lending commitments, will be measured based on historical experience, current conditions and forecasts that affect the collectability of the reported amount. The firm has substantially completed development of credit loss models for significant loan portfolios and is in the process of testing these models and validating data inputs, while continuing to develop the policies, systems and controls that will be required to implement CECL. Based on the work completed to date, the current loan portfolio and the weighted average of a range of current forecasts of future economic conditions, the firm estimates that the allowance for credit losses will increase by approximately $600 million to $800 million when CECL is adopted. The estimated increase is driven by the fact that the allowance will cover expected credit losses over the full expected life of the loan portfolios and will also take into account forecasts of expected future economic conditions. This increased allowance will not impact the firm’s realized losses in these loan portfolios. In addition, an allowance will be recorded for certain purchased loans with deterioration in credit quality since origination with a corresponding increase to their gross carrying value. Ultimately, the extent of the impact of adoption of this ASU on the firm’s consolidated financial statements may vary and will depend on, among other things, the economic environment, the completion of the firm’s models, policies and other management judgments, and the size and type of loan portfolios held by the firm on the date of adoption. Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (ASC 220). In February 2018 , the FASB issued ASU No. 2018 - 02 , “Income Statement — Reporting Comprehensive Income (Topic 220) — Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” This ASU permits a reporting entity to reclassify the income tax effects of the Tax Cuts and Jobs Act (Tax Legislation) on items within accumulated other comprehensive income to retained earnings. The firm adopted this ASU in January 2019 and did not elect to reclassify the income tax effects of Tax Legislation from accumulated other comprehensive income to retained earnings. Therefore, the adoption of the ASU did not have an impact on the firm’s consolidated financial statements.

Financial Instruments Owned and Financial Instruments Sold, But Not Yet Purchased	Note 4. Financial Instruments Owned and Financial Instruments Sold, But Not Yet Purchased Financial instruments owned and financial instruments sold, but not yet purchased are accounted for at fair value either under the fair value option or in accordance with other U.S. GAAP. See Note 6 for information about cash instruments, Note 7 for information about derivatives, and Note 8 for information about other financial assets and financial liabilities at fair value.

See Note 23 for further information about interest income and interest expense. • Gains/(losses) on other principal transactions are included in the firm’s Investing & Lending segment. See Note 25 for net revenues, including net interest income, by product type for Investing & Lending, as well as the amount of net interest income included in Investing & Lending. • Gains/(losses) are not representative of the manner in which the firm manages its business activities because many of the firm’s market-making and client facilitation strategies utilize financial instruments across various product types. Accordingly, gains or losses in one product type frequently offset gains or losses in other product types. For example, most of the firm’s longer-term derivatives across product types are sensitive to changes in interest rates and may be economically hedged with interest rate swaps. Similarly, a significant portion of the firm’s cash instruments and derivatives across product types has exposure to foreign currencies and may be economically hedged with foreign currency contracts.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 5. Fair Value Measurements The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Financial assets are marked to bid prices and financial liabilities are marked to offer prices. Fair value measurements do not include transaction costs. The firm measures certain financial assets and financial liabilities as a portfolio (i.e., based on its net exposure to market and/or credit risks). The best evidence of fair value is a quoted price in an active market. If quoted prices in active markets are not available, fair value is determined by reference to prices for similar instruments, quoted prices or recent transactions in less active markets, or internally developed models that primarily use market-based or independently sourced inputs, including, but not limited to, interest rates, volatilities, equity or debt prices, foreign exchange rates, commodity prices, credit spreads and funding spreads (i.e., the spread or difference between the interest rate at which a borrower could finance a given financial instrument relative to a benchmark interest rate). U.S. GAAP has a three-level hierarchy for disclosure of fair value measurements. This hierarchy prioritizes inputs to the valuation techniques used to measure fair value, giving the highest priority to level 1 inputs and the lowest priority to level 3 inputs. A financial instrument’s level in this hierarchy is based on the lowest level of input that is significant to its fair value measurement. In evaluating the significance of a valuation input, the firm considers, among other factors, a portfolio’s net risk exposure to that input. The fair value hierarchy is as follows: Level 1. Level 2. Level 3. The fair values for substantially all of the firm’s financial assets and financial liabilities are based on observable prices and inputs and are classified in levels 1 and 2 of the fair value hierarchy. Certain level 2 and level 3 financial assets and financial liabilities may require appropriate valuation adjustments that a market participant would require to arrive at fair value for factors, such as counterparty and the firm’s credit quality, funding risk, transfer restrictions, liquidity and bid/offer spreads. Valuation adjustments are generally based on market evidence. See Notes 6 through 8 for further information about fair value measurements of cash instruments, derivatives and other financial assets and financial liabilities at fair value. The table below presents financial assets and financial liabilities accounted for at fair value under the fair value option or in accordance with other U.S. GAAP. As of $ in millions June 2019 March 2019 December 2018 Total level 1 financial assets $196,854 $195,787 $170,463 Total level 2 financial assets 368,056 354,812 354,515 Total level 3 financial assets 22,787 22,596 22,181 Investments in funds at NAV 4,086 4,036 3,936 Counterparty and cash collateral netting (56,747 ) (52,377 ) (49,383 ) Total financial assets at fair value $535,036 $524,854 $501,712 Total assets $944,903 $925,349 $931,796 Total level 3 financial assets divided by: Total assets 2.4% 2.4% 2.4% Total financial assets at fair value 4.3% 4.3% 4.4% Total level 1 financial liabilities $ 56,715 $ 50,605 $ 54,151 Total level 2 financial liabilities 251,854 242,196 258,335 Total level 3 financial liabilities 25,194 26,424 23,804 Counterparty and cash collateral netting (43,395 ) (39,768 ) (39,786 ) Total financial liabilities at fair value $290,368 $279,457 $296,504 Total level 3 financial liabilities divided by total financial liabilities at fair value 8.7% 9.5% 8.0% In the table above: • Counterparty netting among positions classified in the same level is included in that level. • Counterparty and cash collateral netting represents the impact on derivatives of netting across levels of the fair value hierarchy.

Cash Instruments	Note 6. Cash Instruments Cash instruments include U.S. government and agency obligations, non-U.S. non-derivative Level 1 Cash Instruments Level 1 cash instruments include certain money market instruments, U.S. government obligations, most non-U.S. The firm defines active markets for equity instruments based on the average daily trading volume both in absolute terms and relative to the market capitalization for the instrument. The firm defines active markets for debt instruments based on both the average daily trading volume and the number of days with trading activity. Level 2 Cash Instruments Level 2 cash instruments include most money market instruments, most government agency obligations, certain non-U.S. Valuations of level 2 cash instruments can be verified to quoted prices, recent trading activity for identical or similar instruments, broker or dealer quotations or alternative pricing sources with reasonable levels of price transparency. Consideration is given to the nature of the quotations (e.g., indicative or firm) and the relationship of recent market activity to the prices provided from alternative pricing sources. Valuation adjustments are typically made to level 2 cash instruments (i) if the cash instrument is subject to transfer restrictions and/or (ii) for other premiums and liquidity discounts that a market participant would require to arrive at fair value. Valuation adjustments are generally based on market evidence. Level 3 Cash Instruments Level 3 cash instruments have one or more significant valuation inputs that are not observable. Absent evidence to the contrary, level 3 cash instruments are initially valued at transaction price, which is considered to be the best initial estimate of fair value. Subsequently, the firm uses other methodologies to determine fair value, which vary based on the type of instrument. Valuation inputs and assumptions are changed when corroborated by substantive observable evidence, including values realized on sales. Valuation Techniques and Significant Inputs of Level 3 Cash Instruments Valuation techniques of level 3 cash instruments vary by instrument, but are generally based on discounted cash flow techniques. The valuation techniques and the nature of significant inputs used to determine the fair values of each type of level 3 cash instrument are described below: Loans and Securities Backed by Commercial Real Estate. • Market yields implied by transactions of similar or related assets and/or current levels and changes in market indices, such as the CMBX (an index that tracks the performance of commercial mortgage bonds); • Transaction prices in both the underlying collateral and instruments with the same or similar underlying collateral; • A measure of expected future cash flows in a default scenario (recovery rates) implied by the value of the underlying collateral, which is mainly driven by current performance of the underlying collateral, capitalization rates and multiples. Recovery rates are expressed as a percentage of notional or face value of the instrument and reflect the benefit of credit enhancements on certain instruments; and • Timing of expected future cash flows (duration) which, in certain cases, may incorporate the impact of other unobservable inputs (e.g., prepayment speeds). Loans and Securities Backed by Residential Real Estate. • Market yields implied by transactions of similar or related assets; • Transaction prices in both the underlying collateral and instruments with the same or similar underlying collateral; • Cumulative loss expectations, driven by default rates, home price projections, residential property liquidation timelines, related costs and subsequent recoveries; and • Duration, driven by underlying loan prepayment speeds and residential property liquidation timelines. Corporate Debt Instruments. • Market yields implied by transactions of similar or related assets and/or current levels and trends of market indices, such as the CDX (an index that tracks the performance of corporate credit); • Current performance and recovery assumptions and, where the firm uses credit default swaps to value the related cash instrument, the cost of borrowing the underlying reference obligation; and • Duration. Equity Securities. • Industry multiples (primarily EBITDA multiples) and public comparables; • Transactions in similar instruments; • Discounted cash flow techniques; and • Third-party appraisals. The firm also considers changes in the outlook for the relevant industry and financial performance of the issuer as compared to projected performance. Significant inputs include: • Market and transaction multiples; • Discount rates and capitalization rates; and • For equity securities with debt-like features, market yields implied by transactions of similar or related assets, current performance and recovery assumptions, and duration. Other Cash Instruments. non-U.S. • Market yields implied by transactions of similar or related assets and/or current levels and trends of market indices; • Current performance and recovery assumptions and, where the firm uses credit default swaps to value the related cash instrument, the cost of borrowing the underlying reference obligation; and • Duration.

Such securities include investments accounted for at fair value under the fair value option where the firm would otherwise apply the equity method of accounting of $7.95 billion as of June 2019 and $7.91 billion as of December 2018. As of both June 2019 and December 2018, level 3 equity securities primarily consisted of private equity securities. Significant Unobservable Inputs The table below presents the amount of level 3 assets, and ranges and weighted averages of significant unobservable inputs used to value level 3 cash instruments. Level 3 Assets and Range of Significant Unobservable Inputs (Weighted Average) as of $ in millions June 2019 December 2018 Loans and securities backed by commercial real estate Level 3 assets $910 $1,019 Yield 4.3 20.0 10.7 ) 6.9 22.5 12.4 ) Recovery rate 5.4 77.0 45.7 ) 9.7 78.4 42.9 ) Duration (years) 0.4 6.7 3.5 ) 0.4 7.1 3.7 ) Loans and securities backed by residential real estate Level 3 assets $463 $663 Yield 1.2 14.0 8.6 ) 2.6 19.3 9.2 ) Cumulative loss rate 3.0 46.1 27.3 ) 8.3 37.7 19.2 ) Duration (years) 1.1 14.2 7.3 ) 1.4 14.0 6.7 ) Corporate debt instruments Level 3 assets $4,680 $4,224 Yield 1.2 27.0 11.9 ) 0.7 32.3 11.9 ) Recovery rate 0.0 88.6 56.2 ) 0.0 78.0 57.8 ) Duration (years) 0.6 6.2 3.0 ) 0.4 13.5 3.4 ) Equity securities Level 3 assets $11,281 $10,725 Multiples 0.8 27.0 7.7 ) 1.0 23.6 (8.1 ) Discount rate/yield 6.5 27.2 13.7 ) 6.5 22.1 14.3 ) Capitalization rate 3.7 16.6 6.3 ) 3.5 12.3 6.1 ) Other cash instruments Level 3 assets $689 $596 Yield 3.6 16.0 13.5 ) 4.1 11.5 9.2 ) Duration (years) 1.7 4.8 2.8 ) 2.2 4.8 2.8 ) In the table above: • Ranges represent the significant unobservable inputs that were used in the valuation of each type of cash instrument. • Weighted averages are calculated by weighting each input by the relative fair value of the cash instruments. • The ranges and weighted averages of these inputs are not representative of the appropriate inputs to use when calculating the fair value of any one cash instrument. For example, the highest multiple for private equity securities is appropriate for valuing a specific private equity security but may not be appropriate for valuing any other private equity security. Accordingly, the ranges of inputs do not represent uncertainty in, or possible ranges of, fair value measurements of level 3 cash instruments. • Increases in yield, discount rate, capitalization rate, duration or cumulative loss rate used in the valuation of level 3 cash instruments would have resulted in a lower fair value measurement, while increases in recovery rate or multiples would have resulted in a higher fair value measurement as of both June 2019 and December 2018. Due to the distinctive nature of each level 3 cash instrument, the interrelationship of inputs is not necessarily uniform within each product type. • Loans and securities backed by commercial and residential real estate, corporate debt instruments and other cash instruments are valued using discounted cash flows, and equity securities are valued using market comparables and discounted cash flows. • The fair value of any one instrument may be determined using multiple valuation techniques. For example, market comparables and discounted cash flows may be used together to determine fair value. Therefore, the level 3 balance encompasses both of these techniques. Level 3 Rollforward The table below presents a summary of the changes in fair value for level 3 cash instrument assets and liabilities.

If a cash instrument asset or liability was transferred to level 3 during a reporting period, its entire gain or loss for the period is classified in level 3. • For level 3 cash instrument assets, increases are shown as positive amounts, while decreases are shown as negative amounts. For level 3 cash instrument liabilities, increases are shown as negative amounts, while decreases are shown as positive amounts. • Level 3 cash instruments are frequently economically hedged with level 1 and level 2 cash instruments and/or level 1, level 2 or level 3 derivatives. Accordingly, gains or losses that are classified in level 3 can be partially offset by gains or losses attributable to level 1 or level 2 cash instruments and/or level 1, level 2 or level 3 derivatives.

The realized gains on sales of such securities were $95 million for the three months ended June 2019 and $131 million for the six months ended June 2019, and were included in the consolidated statements of earnings. • The gross unrealized gains included in accumulated other comprehensive income/(loss) were $137 million as of June 2019. The gross unrealized losses included in accumulated other comprehensive income/(loss) were $ 153 • Available-for-sale Investments in Funds at Net Asset Value Per Share Cash instruments at fair value include investments in funds that are measured at NAV of the investment fund. The firm uses NAV to measure the fair value of its fund investments when (i) the fund investment does not have a readily determinable fair value and (ii) the NAV of the investment fund is calculated in a manner consistent with the measurement principles of investment company accounting, including measurement of the investments at fair value. Substantially all of the firm’s investments in funds at NAV consist of investments in firm-sponsored private equity, credit, real estate and hedge funds where the firm co-invests Private equity funds primarily invest in a broad range of industries worldwide, including leveraged buyouts, recapitalizations, growth investments and distressed investments. Credit funds generally invest in loans and other fixed income instruments and are focused on providing private high-yield capital for leveraged and management buyout transactions, recapitalizations, financings, refinancings, acquisitions and restructurings for private equity firms, private family companies and corporate issuers. Real estate funds invest globally, primarily in real estate companies, loan portfolios, debt recapitalizations and property. Private equity, credit and real estate funds are closed-end The firm also invests in hedge funds, primarily multi-disciplinary hedge funds that employ a fundamental bottom-up Many of the funds described above are “covered funds” as defined in the Volcker Rule of the U.S. Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank Act). The Board of Governors of the Federal Reserve System (FRB) extended the conformance period to July 2022 for the firm’s investments in, and relationships with, certain legacy “illiquid funds” (as defined in the Volcker Rule) that were in place prior to December 2013.

Derivatives and Hedging Activities	Note 7. Derivatives and Hedging Activities Derivative Activities Derivatives are instruments that derive their value from underlying asset prices, indices, reference rates and other inputs, or a combination of these factors. Derivatives may be traded on an exchange (exchange-traded) or they may be privately negotiated contracts, which are usually referred to as OTC derivatives. Certain of the firm’s OTC derivatives are cleared and settled through central clearing counterparties (OTC-cleared), Market Making. Risk Management. instrument-by-instrument non-U.S. The firm enters into various types of derivatives, including: • Futures and Forwards. • Swaps. • Options. Derivatives are reported on a net-by-counterparty The tables below present the gross fair value and the notional amounts of derivative contracts by major product type, the amounts of counterparty and cash collateral netting in the consolidated statements of financial condition, as well as cash and securities collateral posted and received under enforceable credit support agreements that do not meet the criteria for netting under U.S. GAAP.

Valuation Techniques for Derivatives The firm’s level 2 and level 3 derivatives are valued using derivative pricing models (e.g., discounted cash flow models, correlation models, and models that incorporate option pricing methodologies, such as Monte Carlo simulations). Price transparency of derivatives can generally be characterized by product type, as described below. • Interest Rate. 10-year 2-year • Credit. • Currency. • Commodity. • Equity. Liquidity is essential to observability of all product types. If transaction volumes decline, previously transparent prices and other inputs may become unobservable. Conversely, even highly structured products may at times have trading volumes large enough to provide observability of prices and other inputs. See Note 5 for an overview of the firm’s fair value measurement policies. Level 1 Derivatives Level 1 derivatives include short-term contracts for future delivery of securities when the underlying security is a level 1 instrument, and exchange-traded derivatives if they are actively traded and are valued at their quoted market price. Level 2 Derivatives Level 2 derivatives include OTC derivatives for which all significant valuation inputs are corroborated by market evidence and exchange-traded derivatives that are not actively traded and/or that are valued using models that calibrate to market-clearing levels of OTC derivatives. The selection of a particular model to value a derivative depends on the contractual terms of and specific risks inherent in the instrument, as well as the availability of pricing information in the market. For derivatives that trade in liquid markets, model selection does not involve significant management judgment because outputs of models can be calibrated to market-clearing levels. Valuation models require a variety of inputs, such as contractual terms, market prices, yield curves, discount rates (including those derived from interest rates on collateral received and posted as specified in credit support agreements for collateralized derivatives), credit curves, measures of volatility, prepayment rates, loss severity rates and correlations of such inputs. Significant inputs to the valuations of level 2 derivatives can be verified to market transactions, broker or dealer quotations or other alternative pricing sources with reasonable levels of price transparency. Consideration is given to the nature of the quotations (e.g., indicative or firm) and the relationship of recent market activity to the prices provided from alternative pricing sources. Level 3 Derivatives Level 3 derivatives are valued using models which utilize observable level 1 and/or level 2 inputs, as well as unobservable level 3 inputs. The significant unobservable inputs used to value the firm’s level 3 derivatives are described below. • For level 3 interest rate and currency derivatives, significant unobservable inputs include correlations of certain currencies and interest rates (e.g., the correlation between Euro inflation and Euro interest rates). In addition, for level 3 interest rate derivatives, significant unobservable inputs include specific interest rate volatilities. • For level 3 credit derivatives, significant unobservable inputs include illiquid credit spreads and upfront credit points, which are unique to specific reference obligations and reference entities, recovery rates and certain correlations required to value credit derivatives (e.g., the likelihood of default of the underlying reference obligation relative to one another). • For level 3 commodity derivatives, significant unobservable inputs include volatilities for options with strike prices that differ significantly from current market prices and prices or spreads for certain products for which the product quality or physical location of the commodity is not aligned with benchmark indices. • For level 3 equity derivatives, significant unobservable inputs generally include equity volatility inputs for options that are long-dated and/or have strike prices that differ significantly from current market prices. In addition, the valuation of certain structured trades requires the use of level 3 correlation inputs, such as the correlation of the price performance of two or more individual stocks or the correlation of the price performance for a basket of stocks to another asset class, such as commodities. Subsequent to the initial valuation of a level 3 derivative, the firm updates the level 1 and level 2 inputs to reflect observable market changes and any resulting gains and losses are classified in level 3. Level 3 inputs are changed when corroborated by evidence, such as similar market transactions, third-party pricing services and/or broker or dealer quotations or other empirical market data. In circumstances where the firm cannot verify the model value by reference to market transactions, it is possible that a different valuation model could produce a materially different estimate of fair value. See below for further information about significant unobservable inputs used in the valuation of level 3 derivatives. Valuation Adjustments Valuation adjustments are integral to determining the fair value of derivative portfolios and are used to adjust the mid-market In addition, for derivatives that include significant unobservable inputs, the firm makes model or exit price adjustments to account for the valuation uncertainty present in the transaction. Fair Value of Derivatives by Level The table below presents the fair value of derivatives on a gross basis by level and major product type, as well as the impact of netting. $ in millions Level 1 Level 2 Level 3 Total As of June 2019 Assets Interest rates $ 4 $ 292,427 $ 571 $ 293,002 Credit 94 16,237 3,325 19,656 Currencies – 79,089 229 79,318 Commodities – 10,821 456 11,277 Equities 24 44,141 1,051 45,216 Gross fair value 122 442,715 5,632 448,469 Counterparty netting in levels – (346,733 ) (870 ) (347,603 ) Subtotal $122 $ 95,982 $ 4,762 $ 100,866 Cross-level counterparty netting (179 ) Cash collateral netting (56,568 ) Net fair value $ Liabilities Interest rates $ (3 ) $(267,680 ) $ ) $(268,224 ) Credit (43 ) (18,043 ) (1,649 ) (19,735 ) Currencies – (80,117 ) (260 ) (80,377 ) Commodities – (14,502 ) (322 ) (14,824 ) Equities (17 ) (50,112 ) (2,262 ) (52,391 ) Gross fair value (63 ) (430,454 ) (5,034 ) (435,551 ) Counterparty netting in levels – 346,733 870 347,603 Subtotal $ (63 ) $ (83,721 ) $(4,164 ) $ ) Cross-level counterparty netting 179 Cash collateral netting 43,216 Net fair value $ ) As of December 2018 Assets Interest rates $ 12 $ $ 408 $ 236,100 Credit – 15,992 3,444 19,436 Currencies – 85,837 681 86,518 Commodities – 17,193 431 17,624 Equities 10 47,168 940 48,118 Gross fair value 22 401,870 5,904 407,796 Counterparty netting in levels – (312,611 ) (956 ) (313,567 ) Subtotal $ 22 $ 89,259 $ 4,948 $ 94,229 Cross-level counterparty netting (659 ) Cash collateral netting (48,724 ) Net fair value $ 44,846 Liabilities Interest rates $(24 ) $(215,662 ) $ (517 ) $(216,203 ) Credit – (16,529 ) (1,772 ) (18,301 ) Currencies – (88,663 ) (220 ) (88,883 ) Commodities – (19,808 ) (319 ) (20,127 ) Equities (37 ) (49,910 ) (2,486 ) (52,433 ) Gross fair value (61 ) (390,572 ) (5,314 ) (395,947 ) Counterparty netting in levels – 312,611 956 313,567 Subtotal $(61 ) $ (77,961 ) $(4,358 ) $ (82,380 ) Cross-level counterparty netting 659 Cash collateral netting 39,127 Net fair value $ (42,594 ) In the table above: • The gross fair values exclude the effects of both counterparty netting and collateral netting, and therefore are not representative of the firm’s exposure. • Counterparty netting is reflected in each level to the extent that receivable and payable balances are netted within the same level and is included in counterparty netting in levels. Where the counterparty netting is across levels, the netting is included in cross-level counterparty netting. • Derivative assets are shown as positive amounts and derivative liabilities are shown as negative amounts. Significant Unobservable Inputs The table below presents the amount of level 3 assets (liabilities), and ranges, averages and medians of significant unobservable inputs used to value level 3 derivatives. Level 3 Assets (Liabilities) and Range of Significant $ in millions June 2019 December 2018 Interest rates, net $30 $(109) Correlation ( 55 81 51 60 (10) 86 66 64 Volatility (bps) 31 to 150 79 76 31 150 74 65 Credit, net $1,676 $1,672 Credit spreads (bps) 1 559 95 /58 1 810 109 63 Upfront credit points 1 99 41 35 2 99 44 40 Recovery rates 25 82 43 40 25 70 40 40 Currencies, net $(31) $461 Correlation 10 70 44 47 10 70 40 36 Commodities, net $134 $112 Volatility 9 57 25 24 10 75 28 27 Natural gas spread $ (2.16 3.06 ($ (0.22 $ (2.32) 4.68 ($ (0.26) (0.30) Oil spread $( 6.38 ($ 6.32 6.66 $ (3.44) 16.62 ($ 4.53 3.94 Equities, net $( 1,211 $(1,546) Correlation ( 69 97 47 49 (68) 97 48 51 Volatility 3 103 16 12 3 102 20 18 In the table above: • Derivative assets are shown as positive amounts and derivative liabilities are shown as negative amounts. • Ranges represent the significant unobservable inputs that were used in the valuation of each type of derivative. • Averages represent the arithmetic average of the inputs and are not weighted by the relative fair value or notional of the respective financial instruments. An average greater than the median indicates that the majority of inputs are below the average. For example, the difference between the average and the median for credit spreads indicates that the majority of the inputs fall in the lower end of the range. • The ranges, averages and medians of these inputs are not representative of the appropriate inputs to use when calculating the fair value of any one derivative. For example, the highest correlation for interest rate derivatives is appropriate for valuing a specific interest rate derivative but may not be appropriate for valuing any other interest rate derivative. Accordingly, the ranges of inputs do not represent uncertainty in, or possible ranges of, fair value measurements of level 3 derivatives. • Interest rates, currencies and equities derivatives are valued using option pricing models, credit derivatives are valued using option pricing, correlation and discounted cash flow models, and commodities derivatives are valued using option pricing and discounted cash flow models. • The fair value of any one instrument may be determined using multiple valuation techniques. For example, option pricing models and discounted cash flows models are typically used together to determine fair value. Therefore, the level 3 balance encompasses both of these techniques. • Correlation within currencies and equities includes cross-product type correlation. • Natural gas spread represents the spread per million British thermal units of natural gas. • Oil spread represents the spread per barrel of oil and refined products. Range of Significant Unobservable Inputs The following is information about the ranges of significant unobservable inputs used to value the firm’s level 3 derivative instruments: • Correlation. • Volatility. • Credit spreads, upfront credit points and recovery rates. • Commodity prices and spreads. Sensitivity of Fair Value Measurement to Changes in Significant Unobservable Inputs The following is a description of the directional sensitivity of the firm’s level 3 fair value measurements, as of both June 2019 and December 2018, to changes in significant unobservable inputs, in isolation: • Correlation. • Volatility. • Credit spreads, upfront credit points and recovery rates. • Commodity prices and spreads. Due to the distinctive nature of each of the firm’s level 3 derivatives, the interrelationship of inputs is not necessarily uniform within each product type. Level 3 Rollforward The table below presents a summary of the changes in fair value for level 3 derivatives.

If a derivative was transferred into level 3 during a reporting period, its entire gain or loss for the period is classified in level 3. • Positive amounts for transfers into level 3 and negative amounts for transfers out of level 3 represent net transfers of derivative assets. Negative amounts for transfers into level 3 and positive amounts for transfers out of level 3 represent net transfers of derivative liabilities. • A derivative with level 1 and/or level 2 inputs is classified in level 3 in its entirety if it has at least one significant level 3 input. • If there is one significant level 3 input, the entire gain or loss from adjusting only observable inputs (i.e., level 1 and level 2 inputs) is classified in level 3. • Gains or losses that have been classified in level 3 resulting from changes in level 1 or level 2 inputs are frequently offset by gains or losses attributable to level 1 or level 2 derivatives and/or level 1, level 2 and level 3 cash instruments. As a result, gains/(losses) included in the level 3 rollforward below do not necessarily represent the overall impact on the firm’s results of operations, liquidity or capital resources.

Transfers into level 3 derivatives during the three months ended June 2019 were not material. Transfers out of level 3 derivatives during the three months ended June 2019 primarily reflected transfers of certain equity derivative liabilities to level 2, principally due to certain unobservable inputs no longer being significant to the valuation of these derivatives. Six Months Ended June 2019. 127 20 107 92 35 The net unrealized losses on level 3 derivatives for the six months ended June 2019 were primarily attributable to losses on certain currency derivatives, primarily reflecting the impact of a decrease in interest rates and losses on certain equity derivatives, primarily reflecting the impact of an increase in underlying equity prices, partially offset by gains on certain interest rate derivatives, primarily reflecting the impact of a decrease in interest rates. Both transfers into level 3 derivatives and transfers out of level 3 derivatives during the six months ended June 2019 were not material. Three Months Ended June 2018. The net unrealized gains on level 3 derivatives for the three months ended June 2018 were primarily attributable to gains on certain credit derivatives, reflecting the impact of changes in credit spreads and foreign exchange rates, and gains on certain equity derivatives, reflecting the impact of increases in equity prices. Transfers into level 3 derivatives during the three months ended June 2018 primarily reflected transfers of certain credit derivative assets from level 2, primarily due to unobservable credit spread inputs becoming significant to the net risk of certain portfolios. Transfers out of level 3 derivatives during the three months ended June 2018 were not material. Six Months Ended June 2018. The net unrealized gains on level 3 derivatives for the six months ended June 2018 were primarily attributable to gains on certain equity derivatives, reflecting the impact of changes in equity prices, and gains on certain currency derivatives, primarily reflecting the impact of changes in foreign exchange rates. Transfers into level 3 derivatives during the six months ended June 2018 reflected transfers of certain commodity derivative assets from level 2, principally due to increased significance of unobservable volatility inputs used to value these derivatives. Transfers out of level 3 derivatives during the six months ended June 2018 primarily reflected transfers of certain equity derivative liabilities to level 2, principally due to increased transparency of volatility and correlation inputs used to value these derivatives and transfers of certain credit derivative liabilities to level 2, primarily due to unobservable credit spread inputs no longer being significant to the net risk of certain portfolios.

Where the counterparty netting is across tenor categories, the netting is included in cross-tenor counterparty netting. Credit Derivatives The firm enters into a broad array of credit derivatives in locations around the world to facilitate client transactions and to manage the credit risk associated with market-making and investing and lending activities. Credit derivatives are actively managed based on the firm’s net risk position. Credit derivatives are generally individually negotiated contracts and can have various settlement and payment conventions. Credit events include failure to pay, bankruptcy, acceleration of indebtedness, restructuring, repudiation and dissolution of the reference entity. The firm enters into the following types of credit derivatives: • Credit Default Swaps. • Credit Options. • Credit Indices, Baskets and Tranches. pro-rata • Total Return Swaps. The firm economically hedges its exposure to written credit derivatives primarily by entering into offsetting purchased credit derivatives with identical underliers. Substantially all of the firm’s purchased credit derivative transactions are with financial institutions and are subject to stringent collateral thresholds. In addition, upon the occurrence of a specified trigger event, the firm may take possession of the reference obligations underlying a particular written credit derivative, and consequently may, upon liquidation of the reference obligations, recover amounts on the underlying reference obligations in the event of default. As of June 2019, written credit derivatives had a total gross notional amount of $ 530.09 615.11 85.02 The table below presents information about credit derivatives.

The firm is less likely to pay or otherwise be required to perform where the credit spread and the tenor are lower. • Offsetting purchased credit derivatives represent the notional amount of purchased credit derivatives that economically hedge written credit derivatives with identical underliers. • Other purchased credit derivatives represent the notional amount of all other purchased credit derivatives not included in offsetting. Impact of Credit Spreads on Derivatives The firm realizes gains or losses relating to changes in credit risk through the unwind of derivative contracts and changes in credit mitigants. The net gains/(losses), including hedges, attributable to the impact of changes in credit exposure and credit spreads (counterparty and the firm’s) on derivatives was $ (35) 198 Bifurcated Embedded Derivatives The table below presents the fair value and the notional amount of derivatives that have been bifurcated from their related borrowings. As of $ in millions June 2019 December 2018 Fair value of assets $ 1,005 $ 980 Fair value of liabilities 1,494 1,297 Net liability $ 489 $ 317 Notional amount $ 10,788 $10,229 In the table above, these derivatives, which are recorded at fair value, primarily consist of interest rate, equity and commodity products and are included in unsecured short-term and long-term borrowings with the related borrowings. Derivatives with Credit-Related Contingent Features Certain of the firm’s derivatives have been transacted under bilateral agreements with counterparties who may require the firm to post collateral or terminate the transactions based on changes in the firm’s credit ratings. The firm assesses the impact of these bilateral agreements by determining the collateral or termination payments that would occur assuming a downgrade by all rating agencies. A downgrade by any one rating agency, depending on the agency’s relative ratings of the firm at the time of the downgrade, may have an impact which is comparable to the impact of a downgrade by all rating agencies. The table below presents information about net derivative liabilities under such bilateral agreements (excluding application of collateral posted), the related fair value of collateral posted and the additional collateral or termination payments that could have been called by counterparties in the event of a one-notch two-notch As of $ in millions June 2019 December 2018 Net derivative liabilities under bilateral agreements $ 33,550 $29,583 Collateral posted $ 29,074 $24,393 Additional collateral or termination payments: One-notch $ 329 $ 262 Two-notch $ 1,061 $ 959 Hedge Accounting The firm applies hedge accounting for (i) certain interest rate swaps used to manage the interest rate exposure of certain fixed-rate unsecured long-term and short-term borrowings and certain fixed-rate cert

Fair Value Disclosures [Abstract]
Fair Value Option	Note 8. Fair Value Option Other Financial Assets and Financial Liabilities at Fair Value In addition to cash and derivative instruments included in financial instruments owned and financial instruments sold, but not yet purchased, the firm accounts for certain of its other financial assets and financial liabilities at fair value, substantially all under the fair value option. The primary reasons for electing the fair value option are to: • Reflect economic events in earnings on a timely basis; • Mitigate volatility in earnings from using different measurement attributes (e.g., transfers of financial instruments owned accounted for as financings are recorded at fair value, whereas the related secured financing would be recorded on an accrual basis absent electing the fair value option); and • Address simplification and cost-benefit considerations (e.g., accounting for hybrid financial instruments at fair value in their entirety versus bifurcation of embedded derivatives and hedge accounting for debt hosts). Hybrid financial instruments are instruments that contain bifurcatable embedded derivatives and do not require settlement by physical delivery of nonfinancial assets (e.g., physical commodities). If the firm elects to bifurcate the embedded derivative from the associated debt, the derivative is accounted for at fair value and the host contract is accounted for at amortized cost, adjusted for the effective portion of any fair value hedges. If the firm does not elect to bifurcate, the entire hybrid financial instrument is accounted for at fair value under the fair value option. Other financial assets and financial liabilities accounted for at fair value under the fair value option include: • Repurchase agreements and substantially all resale agreements; • Securities borrowed and loaned in Fixed Income, Currency and Commodities (FICC) Client Execution; • Substantially all other secured financings, including transfers of assets accounted for as financings; • Certain unsecured short-term and long-term borrowings, substantially all of which are hybrid financial instruments; • Certain customer and other receivables, including transfers of assets accounted for as secured loans and certain margin loans; and • Certain time deposits (deposits with no stated maturity are not eligible for a fair value option election), including structured certificates of deposit, which are hybrid financial instruments.

Valuation Techniques and Significant Inputs Other financial assets and financial liabilities at fair value are generally valued based on discounted cash flow techniques, which incorporate inputs with reasonable levels of price transparency, and are generally classified in level 2 because the inputs are observable. Valuation adjustments may be made for liquidity and for counterparty and the firm’s credit quality. See below for information about the significant inputs (including the significant unobservable inputs) used to value other financial assets and financial liabilities at fair value. Resale and Repurchase Agreements and Securities Borrowed and Loaned. Other Secured Financings. Unsecured Short-term and Long-term Borrowings. Certain of the firm’s unsecured short-term and long-term borrowings are classified in level 3, substantially all of which are hybrid financial instruments. As the significant unobservable inputs used to value hybrid financial instruments primarily relate to the embedded derivative component of these borrowings, these inputs are incorporated in the firm’s derivative disclosures related to unobservable inputs in Note 7. Customer and Other Receivables. Deposits. The firm’s deposits that are classified in level 3 are hybrid financial instruments. As the significant unobservable inputs used to value such instruments primarily relate to the embedded derivative component of these deposits, these inputs are incorporated in the firm’s derivative disclosures related to unobservable inputs in Note 7.

If a financial asset or financial liability was transferred to level 3 during a reporting period, its entire gain or loss for the period is classified in level 3. • For level 3 other financial assets, increases are shown as positive amounts, while decreases are shown as negative amounts. For level 3 other financial liabilities, increases are shown as negative amounts, while decreases are shown as positive amounts. • Level 3 other financial assets and financial liabilities are frequently economically hedged with cash instruments and derivatives. Accordingly, gains or losses that are classified in level 3 can be partially offset by gains or losses attributable to level 1, 2 or 3 cash instruments or derivatives. As a result, gains or losses included in the level 3 rollforward below do not necessarily represent the overall impact on the firm’s results of operations, liquidity or capital resources.

Three Months Ended June 2018. The net unrealized gains on level 3 other financial liabilities for the three months ended June 2018 primarily reflected gains on certain hybrid financial instruments included in unsecured long-term borrowings, principally due to the impact of wider credit spreads, changes in foreign exchange rates and interest rates, and gains on certain hybrid financial instruments included in unsecured short-term borrowings, principally due to changes in foreign exchange rates. Transfers into level 3 other financial liabilities during the three months ended June 2018 primarily reflected transfers of certain hybrid financial instruments included in unsecured short-term and long-term borrowings from level 2, principally due to reduced transparency of certain volatility and correlation inputs used to value these instruments. Transfers out of level 3 other financial liabilities during the three months ended June 2018 primarily reflected transfers of certain hybrid financial instruments included in unsecured short-term borrowings to level 2, principally due to increased transparency of inputs used to value these instruments as a result of market transactions in similar instruments, and transfers of certain hybrid financial instruments included in unsecured long-term borrowings to level 2, principally due to increased transparency of certain volatility inputs used to value these instruments. Six Months Ended June 2018. The net unrealized gains on level 3 other financial liabilities for the six months ended June 2018 primarily reflected gains on certain hybrid financial instruments included in unsecured long-term borrowings, principally due to the impact of wider credit spreads, changes in interest rates and a decrease in global equity prices, and gains on certain hybrid financial instruments included in unsecured short-term borrowings, principally due to a decrease in global equity prices and changes in foreign exchange rates.

Gains and Losses on Financial Assets and Financial Liabilities Accounted for at Fair Value Under the Fair Value Option The table below presents the gains and losses recognized in earnings as a result of the firm electing to apply the fair value option to certain financial assets and financial liabilities. Three Months Six Months Ended June $ in millions 2019 2018 2019 2018 Unsecured short-term borrowings $ (469 ) $(101 ) $(2,085 ) $ (15 ) Unsecured long-term borrowings (1,920 ) 421 (4,149 ) 1,122 Other liabilities (34 ) – (28 ) (17 ) Other (179 ) (126 ) (708 ) 40 Total $(2,602 ) $ 194 $(6,970 ) $1,130 In the table above: • Gains/(losses) are included in market making and other principal transactions. • Gains/(losses) exclude contractual interest, which is included in interest income and interest expense, for all instruments other than hybrid financial instruments. See Note 23 for further information about interest income and interest expense. • Gains/(losses) included in unsecured short-term and long-term borrowings were substantially all related to the embedded derivative component of hybrid financial instruments for both the three and six months ended June 2019 and June 2018. These gains and losses would have been recognized under other U.S. GAAP even if the firm had not elected to account for the entire hybrid financial instrument at fair value. • Other primarily consists of gains/(losses) on customer and other receivables, deposits and other secured financings. Excluding the gains and losses on the instruments accounted for at fair value under the fair value option described above, market making and other principal transactions primarily represent gains and losses on financial instruments owned and financial instruments sold, but not yet purchased. Loans and Lending Commitments The table below presents the difference between the aggregate fair value and the aggregate contractual principal amount for loans and long-term receivables for which the fair value option was elected. As of $ in millions June 2019 December 2018 Performing loans and long-term receivables Aggregate contractual principal in excess of fair value $ 643 $1,837 Loans on nonaccrual status and/or more than 90 days past due Aggregate contractual principal in excess of fair value $6,896 $5,260 Aggregate fair value of loans on nonaccrual status and/or more than 90 days past due $2,645 $2,010 In the table above, the aggregate contractual principal amount of loans on nonaccrual status and/or more than 90 days past due (which excludes loans carried at zero fair value and considered uncollectible) exceeds the related fair value primarily because the firm regularly purchases loans, such as distressed loans, at values significantly below the contractual principal amounts. The fair value of unfunded lending commitments for which the fair value option was elected was a liability of $ 22 Long-Term Debt Instruments The difference between the aggregate contractual principal amount and the related fair value of long-term other secured financings for which the fair value option was elected was not material as of both June 2019 and December 2018. The aggregate contractual principal amount of unsecured long-term borrowings for which the fair value option was elected exceeded the related fair value by $1.06 billion as of June 2019 and $3.47 billion as of December 2018. The amounts above include both principal-protected and non-principal-protected Impact of Credit Spreads on Loans and Lending Commitments The estimated net gain attributable to changes in instrument-specific credit spreads on loans and lending commitments for which the fair value option was elected was $ 106 183 Debt Valuation Adjustment The firm calculates the fair value of financial liabilities for which the fair value option is elected by discounting future cash flows at a rate which incorporates the firm’s credit spreads. The table below presents information about the net debt valuation adjustment (DVA) gains/(losses) on financial liabilities for which the fair value option was elected. Three Months Six Months Ended June $ in millions 2019 2018 2019 2018 DVA (pre-tax) $(413 ) $1,167 $(2,302 ) $1,526 DVA (net of tax) $(311 ) $ 878 $(1,728 ) $1,148 In the table above: • DVA (net of tax) is included in debt valuation adjustment in the consolidated statements of comprehensive income. • The gains/(losses) reclassified to earnings from accumulated other comprehensive income/(loss) upon extinguishment of such financial liabilities were not material for both the three and six months ended June 2019 and June 2018.

Loans Receivable	Note 9. Loans Receivable Loans receivable consists of loans held for investment that are accounted for at amortized cost net of allowance for loan losses. Interest on loans receivable is recognized over the life of the loan and is recorded on an accrual basis. The table below presents information about loans receivable. As of $ in millions June 2019 December 2018 Corporate loans $42,950 $ 37,283 PWM loans 17,280 17,518 Commercial real estate loans 11,676 11,441 Residential real estate loans 5,308 7,284 Consumer loans 4,754 4,536 Other loans 3,013 3,594 Total loans receivable, gross 84,981 81,656 Allowance for loan losses (1,212 ) (1,066 ) Total loans receivable $ 83,769 $ 80,590 The fair value of loans receivable was $84.23 billion as of June 2019 and $ 80.74 40.64 40.10 The following is a description of the captions in the table above: • Corporate Loans. • Private Wealth Management (PWM) Loans. • Commercial Real Estate Loans. • Residential Real Estate Loans. • Consumer Loans. • Other Loans. Lending Commitments The table below presents information about lending commitments that are held for investment and accounted for on an accrual basis. As of $ in millions June 2019 December 2018 Corporate $112,106 $113,484 Other 8,296 7,513 Total $120,402 $120,997 In the table above: • Corporate lending commitments primarily relates to the firm’s relationship lending activities. • Other lending commitments primarily relates to lending commitments extended to clients who warehouse assets backed by real estate and other assets and in connection with commercial real estate financing. • The carrying value of lending commitments were liabilities of $458 443 286 • The estimated fair value of such lending commitments were liabilities of $3.15 billion as of June 2019 and $ 3.78 1.12 2.66 PCI Loans Loans receivable includes PCI loans, which represent acquired loans or pools of loans with evidence of credit deterioration subsequent to their origination and where it is probable, at acquisition, that the firm will not be able to collect all contractually required payments. Loans acquired within the same reporting period, which have at least two common risk characteristics, one of which relates to their credit risk, are eligible to be pooled together and considered a single unit of account. PCI loans are initially recorded at the acquisition price and the difference between the acquisition price and the expected cash flows (accretable yield) is recognized as interest income over the life of such loans or pools of loans on an effective yield method. Expected cash flows on PCI loans are determined using various inputs and assumptions, including default rates, loss severities, recoveries, amount and timing of prepayments and other macroeconomic indicators. The tables below present information about PCI loans. As of $ in millions June December 2018 Commercial real estate loans $ 496 $ 581 Residential real estate loans 1,834 2,457 Other loans 2 4 Total gross carrying value $2,332 $ 3,042 Total outstanding principal balance $4,517 $ 5,576 Total accretable yield $ 333 $ 459 Three Months Six Months $ in millions 2019 2018 2019 2018 Acquired during the period Fair value $ – $ 298 $ – $ 298 Expected cash flows $ – $ 328 $ – $ 328 Contractually required cash flows $ – $ 704 $ – $ 704 In the table above: • Fair value, expected cash flows and contractually required cash flows were as of the acquisition date. • Expected cash flows represents the cash flows expected to be received over the life of the loan or as a result of liquidation of the underlying collateral. • Contractually required cash flows represents cash flows required to be repaid by the borrower over the life of the loan. Credit Quality Risk Assessment. The firm enters into economic hedges to mitigate credit risk on certain loans receivable and corporate lending commitments (both of which are held for investment) related to relationship lending activities. Such hedges are accounted for at fair value. See Note 18 for further information about these lending commitments and associated hedges. The table below presents gross loans receivable (excluding PCI and consumer loans of $7.09 billion as of June 2019 and $ 7.58 $ in millions Loans Lending Commitments Total Credit Rating Equivalent As of June 2019 Investment-grade $28,703 $ 77,562 $106,265 Non-investment-grade 49,192 42,840 92,032 Total $77,895 $120,402 $198,297 As of December 2018 Investment-grade $ 28,290 $ 81,959 $ 110,249 Non-investment-grade 45,788 39,038 84,826 Total $ 74,078 $ 120,997 $ 195,075 Regulatory Risk Rating As of June 2019 Non-criticized/pass $72,133 $117,567 $189,700 Criticized 5,762 2,835 8,597 Total $77,895 $120,402 $198,297 As of December 2018 Non-criticized/pass $ 70,153 $ 117,923 $ 188,076 Criticized 3,925 3,074 6,999 Total $ 74,078 $ 120,997 $ 195,075 In the table above, non-criticized/pass For consumer loans, an important credit-quality indicator is the Fair Isaac Corporation (FICO) credit score, which measures a borrower’s creditworthiness by considering factors such as payment and credit history. FICO credit scores are refreshed periodically by the firm to assess the updated creditworthiness of the borrower. The table below presents gross consumer loans receivable and the concentration by refreshed FICO credit score. As of $ in millions June December 2018 Consumer loans, gross $ 4,754 $ 4,536 Refreshed FICO credit score Greater than or equal to 660 87% 88 Less than 660 13 12 Total 100 100 For PCI loans, the firm’s risk assessment process includes reviewing certain key metrics, such as delinquency status, collateral values, expected cash flows and other risk factors. Impaired Loans. In certain circumstances, the firm may also modify the original terms of a loan agreement by granting a concession to a borrower experiencing financial difficulty. Such modifications are considered troubled debt restructurings and typically include interest rate reductions, payment extensions, and modification of loan covenants. Loans modified in a troubled debt restructuring are considered impaired and are subject to specific loan-level reserves. The gross carrying value of impaired loans receivable (excluding PCI loans) on nonaccrual status was $ 917 838 130 27 12 217 208 When it is determined that the firm cannot reasonably estimate expected cash flows on PCI loans or pools of loans, such loans are placed on nonaccrual status. Allowance for Credit Losses The firm’s allowance for credit losses consists of the allowance for losses on loans and lending commitments. The firm’s allowance for loan losses consists of specific loan-level reserves, portfolio level reserves and reserves on PCI loans, as described below: • Specific loan-level reserves are determined on loans (excluding PCI loans) that exhibit credit quality weakness and are therefore individually evaluated for impairment. • Portfolio level reserves are determined on loans (excluding PCI loans) not evaluated for specific loan-level reserves by aggregating groups of loans with similar risk characteristics and estimating the probable loss inherent in the portfolio. • Reserves on PCI loans are recorded when it is determined that the expected cash flows, which are reassessed on a quarterly basis, will be lower than those used to establish the current effective yield for such loans or pools of loans. If the expected cash flows are determined to be significantly higher than those used to establish the current effective yield, such increases are initially recognized as a reduction to any previously recorded allowances for loan losses and any remaining increases are recognized as interest income prospectively over the life of the loan or pools of loans as an increase to the effective yield. The allowance for loan losses is determined using various risk factors, including industry default and loss data, current macroeconomic indicators, borrower’s capacity to meet its financial obligations, borrower’s country of risk, loan seniority and collateral type. In addition, for loans backed by real estate, risk factors include loan to value ratio, debt service ratio and home price index. Risk factors for consumer loans include FICO credit scores and delinquency status. Management’s estimate of loan losses entails judgment about loan collectability at the reporting dates, and there are uncertainties inherent in those judgments. While management uses the best information available to determine this estimate, future adjustments to the allowance may be necessary based on, among other things, changes in the economic environment or variances between actual results and the original assumptions used. Loans are charged off against the allowance for loan losses when deemed to be uncollectible. The firm also records an allowance for losses on lending commitments that are held for investment and accounted for on an accrual basis. Such allowance is determined using the same methodology as the allowance for loan losses, while also taking into consideration the probability of drawdowns or funding, and is included in other liabilities. The table below presents gross loans receivable and lending commitments by impairment methodology. $ in millions Specific Portfolio PCI Total As of June 2019 Loans Receivable Corporate loans $648 $ 42,302 $ – $ 42,950 PWM loans 35 17,245 – 17,280 Commercial real estate loans 71 11,109 496 11,676 Residential real estate loans 163 3,311 1,834 5,308 Consumer loans – 4,754 – 4,754 Other loans – 3,011 2 3,013 Total $917 $ 81,732 $2,332 $ 84,981 Lending Commitments Corporate $ 37 $112,069 $ $112,106 Other 7 8,289 – 8,296 Total $ 44 $120,358 $ – $120,402 As of December 2018 Loans Receivable Corporate loans $ 358 $ 36,925 $ – $ 37,283 PWM loans 46 17,472 – 17,518 Commercial real estate loans 9 10,851 581 11,441 Residential real estate loans 425 4,402 2,457 7,284 Consumer loans – 4,536 – 4,536 Other loans – 3,590 4 3,594 Total $838 $ 77,776 $3,042 $ 81,656 Lending Commitments Corporate $ 31 $ 113,453 $ – $ 113,484 Other – 7,513 – 7,513 Total $ 31 $ 120,966 $ – $ 120,997 In the table above: • Gross loans receivable and lending commitments, subject to specific loan-level reserves, included $469 million as of June 2019 and $ 484 • Gross loans receivable deemed impaired and subject to specific loan-level reserves as a percentage of total gross loans receivable was 1.1 1.0 The table below presents information about the allowance for credit losses.

Collateralized Agreements and Financings	Note 10. Collateralized Agreements and Financings Collateralized agreements are resale agreements and securities borrowed. Collateralized financings are repurchase agreements, securities loaned and other secured financings. The firm enters into these transactions in order to, among other things, facilitate client activities, invest excess cash, acquire securities to cover short positions and finance certain firm activities. Collateralized agreements and financings are presented on a net-by-counterparty The table below presents the carrying value of resale and repurchase agreements and securities borrowed and loaned transactions. As of $ in millions June 2019 December 2018 Resale agreements $137,639 $139,258 Securities borrowed $138,458 $135,285 Repurchase agreements $ 70,879 $ 78,723 Securities loaned $ 13,523 $ 11,808 In the table above: • Substantially all resale agreements and all repurchase agreements are carried at fair value under the fair value option. See Note 8 for further information about the valuation techniques and significant inputs used to determine fair value. • Securities borrowed of $ 25.11 2.73 Resale and Repurchase Agreements A resale agreement is a transaction in which the firm purchases financial instruments from a seller, typically in exchange for cash, and simultaneously enters into an agreement to resell the same or substantially the same financial instruments to the seller at a stated price plus accrued interest at a future date. A repurchase agreement is a transaction in which the firm sells financial instruments to a buyer, typically in exchange for cash, and simultaneously enters into an agreement to repurchase the same or substantially the same financial instruments from the buyer at a stated price plus accrued interest at a future date. Even though repurchase and resale agreements (including “repos- and reverses-to-maturity”) The firm receives financial instruments purchased under resale agreements and makes delivery of financial instruments sold under repurchase agreements. To mitigate credit exposure, the firm monitors the market value of these financial instruments on a daily basis, and delivers or obtains additional collateral due to changes in the market value of the financial instruments, as appropriate. For resale agreements, the firm typically requires collateral with a fair value approximately equal to the carrying value of the relevant assets in the consolidated statements of financial condition. Securities Borrowed and Loaned Transactions In a securities borrowed transaction, the firm borrows securities from a counterparty in exchange for cash or securities. When the firm returns the securities, the counterparty returns the cash or securities. Interest is generally paid periodically over the life of the transaction. In a securities loaned transaction, the firm lends securities to a counterparty in exchange for cash or securities. When the counterparty returns the securities, the firm returns the cash or securities posted as collateral. Interest is generally paid periodically over the life of the transaction. The firm receives securities borrowed and makes delivery of securities loaned. To mitigate credit exposure, the firm monitors the market value of these securities on a daily basis, and delivers or obtains additional collateral due to changes in the market value of the securities, as appropriate. For securities borrowed transactions, the firm typically requires collateral with a fair value approximately equal to the carrying value of the securities borrowed transaction. Securities borrowed and loaned within FICC Client Execution are recorded at fair value under the fair value option. See Note 8 for further information about securities borrowed and loaned accounted for at fair value. Securities borrowed and loaned within Securities Services are recorded based on the amount of cash collateral advanced or received plus accrued interest. As these agreements generally can be terminated on demand, they exhibit little, if any, sensitivity to changes in interest rates. Therefore, the carrying value of such agreements approximates fair value. As these agreements are not accounted for at fair value, they are not included in the firm’s fair value hierarchy in Notes through . Had these agreements been included in the firm’s fair value hierarchy, they would have been classified in level as of both June and December . Offsetting Arrangements The table below presents resale and repurchase agreements and securities borrowed and loaned transactions included in the consolidated statements of financial condition, as well as the amounts not offset in the consolidated statements of financial condition.

Other Secured Financings In addition to repurchase agreements and securities loaned transactions, the firm funds certain assets through the use of other secured financings and pledges financial instruments and other assets as collateral in these transactions. These other secured financings consist of: • Liabilities of consolidated VIEs; • Transfers of assets accounted for as financings rather than sales (e.g., collateralized central bank financings, pledged commodities, bank loans and mortgage whole loans); and • Other structured financing arrangements. Other secured financings includes nonrecourse arrangements. Nonrecourse other secured financings were $ 10.10 The firm has elected to apply the fair value option to substantially all other secured financings because the use of fair value eliminates non-economic volatility in earnings that would arise from using different measurement attributes. See Note 8 for further information about other secured financings that are accounted for at fair value. Other secured financings that are not recorded at fair value are recorded based on the amount of cash received plus accrued interest, which generally approximates fair value. As these financings are not accounted for at fair value, they are not included in the firm’s fair value hierarchy in Notes 5 through 8. Had these financings been included in the firm’s fair value hierarchy, they would have been primarily classified in level 2 as of both June 2019 and December 2018. The table below presents information about other secured financings. $ in millions U.S. Dollar Non-U.S. Total As of June 2019 Other secured financings (short-term): At fair value $ 3,168 $ 4,196 $ 7,364 At amortized cost 137 – 137 Other secured financings (long-term): At fair value 7,718 2,215 9,933 At amortized cost 645 – 645 Total other secured financings $ 11,668 $ 6,411 $ 18,079 Other secured financings collateralized by: Financial instruments $ $5,439 $11,641 Other assets $ 5,466 $ 972 $ 6,438 As of December 2018 Other secured financings (short-term): At fair value $ 3,528 $6,027 $ 9,555 At amortized cost – – – Other secured financings (long-term): At fair value 9,010 2,339 11,349 At amortized cost 529 – 529 Total other secured financings $13,067 $8,366 $21,433 Other secured financings collateralized by: Financial instruments $ 8,960 $7,550 $16,510 Other assets $ 4,107 $ 816 $ 4,923 In the table above: • Short-term other secured financings includes financings maturing within one year of the financial statement date and financings that are redeemable within one year of the financial statement date at the option of the holder. • U.S. dollar-denominated short-term other secured financings at amortized cost had a weighted average interest rate of 4.93 • U.S. dollar-denominated long-term other secured financings at amortized cost had a weighted average interest rate of 2.29 4.02 • Total other secured financings included $ 2.59 2.94 • Other secured financings collateralized by financial instruments included $ 9.04 2.61 The table below presents other secured financings by maturity. $ in millions As of June 2019 Other secured financings (short-term) $ 7,501 Other secured financings (long-term): 2020 2,196 2021 2,088 2022 1,452 2023 1,336 2024 691 2025 - thereafter 2,815 Total other secured financings (long-term) 10,578 Total other secured financings $ 18,079 In the table above: • Long-term other secured financings that are repayable prior to maturity at the option of the firm are reflected at their contractual maturity dates. • Long-term other secured financings that are redeemable prior to maturity at the option of the holder are reflected at the earliest dates such options become exercisable. Collateral Received and Pledged The firm receives cash and securities (e.g., U.S. government and agency obligations, other sovereign and corporate obligations, as well as equity securities) as collateral, primarily in connection with resale agreements, securities borrowed, derivative transactions and customer margin loans. The firm obtains cash and securities as collateral on an upfront or contingent basis for derivative instruments and collateralized agreements to reduce its credit exposure to individual counterparties. In many cases, the firm is permitted to deliver or repledge financial instruments received as collateral when entering into repurchase agreements and securities loaned transactions, primarily in connection with secured client financing activities. The firm is also permitted to deliver or repledge these financial instruments in connection with other secured financings, collateralized derivative transactions and firm or customer settlement requirements. The firm also pledges certain financial instruments owned in connection with repurchase agreements, securities loaned transactions and other secured financings, and other assets (substantially all real estate and cash) in connection with other secured financings to counterparties who may or may not have the right to deliver or repledge them. The table below presents financial instruments at fair value received as collateral that were available to be delivered or repledged and were delivered or repledged. As of $ in millions June 2019 December 2018 Collateral available to be delivered or repledged $711,068 $681,516 Collateral that was delivered or repledged $568,127 $565,625 In the table above, collateral available to be delivered or repledged excludes $ 9.50 2019 and $14.10 billion as of December 2018 of securities received under resale agreements and securities borrowed transactions that contractually had the right to be delivered or repledged, but were segregated for regulatory and other purposes.

Transfers and Servicing [Abstract]
Securitization Activities	Note 11. Securitization Activities The firm securitizes residential and commercial mortgages, corporate bonds, loans and other types of financial assets by selling these assets to securitization vehicles (e.g., trusts, corporate entities and limited liability companies) or through a resecuritization. The firm acts as underwriter of the beneficial interests that are sold to investors. The firm’s residential mortgage securitizations are primarily in connection with government agency securitizations. Beneficial interests issued by securitization entities are debt or equity instruments that give the investors rights to receive all or portions of specified cash inflows to a securitization vehicle and include senior and subordinated interests in principal, interest and/or other cash inflows. The proceeds from the sale of beneficial interests are used to pay the transferor for the financial assets sold to the securitization vehicle or to purchase securities which serve as collateral. The firm accounts for a securitization as a sale when it has relinquished control over the transferred financial assets. Prior to securitization, the firm generally accounts for assets pending transfer at fair value and therefore does not typically recognize significant gains or losses upon the transfer of assets. Net revenues from underwriting activities are recognized in connection with the sales of the underlying beneficial interests to investors. For transfers of financial assets that are not accounted for as sales, the assets remain in financial instruments owned and the transfer is accounted for as a collateralized financing, with the related interest expense recognized over the life of the transaction. See Note 10 for further information about collateralized financings and Note 23 for further information about interest expense. The firm generally receives cash in exchange for the transferred assets but may also have continuing involvement with the transferred financial assets, including ownership of beneficial interests in securitized financial assets, primarily in the form of debt instruments. The firm may also purchase senior or subordinated securities issued by securitization vehicles (which are typically VIEs) in connection with secondary market-making activities. The primary risks included in beneficial interests and other interests from the firm’s continuing involvement with securitization vehicles are the performance of the underlying collateral, the position of the firm’s investment in the capital structure of the securitization vehicle and the market yield for the security. These interests are primarily accounted for at fair value and classified in level 2 of the fair value hierarchy. Interests not accounted for at fair value are carried at amounts that approximate fair value. See Notes 5 through 8 for further information about fair value measurements. The table below presents the amount of financial assets securitized and the cash flows received on retained interests in securitization entities in which the firm had continuing involvement as of the end of the period.

The carrying value of these derivatives and commitments was a net asset of $ 42 1.16 The table below presents information about the weighted average key economic assumptions used in measuring the fair value of mortgage-backed retained interests.

In practice, simultaneous changes in assumptions might magnify or counteract the sensitivities disclosed above. • The constant prepayment rate is included only for positions for which it is a key assumption in the determination of fair value. • The discount rate for retained interests that relate to U.S. government agency-issued collateralized mortgage obligations does not include any credit loss. Expected credit loss assumptions are reflected in the discount rate for the remainder of retained interests. The firm has other retained interests not reflected in the table above with a fair value of $ 134 3.6 2019 , and a fair value of $133 million and a weighted average life of 4.2 years as of December 2018 . Due to the nature and fair value of certain of these retained interests, the weighted average assumptions for constant prepayment and discount rates and the related sensitivity to adverse changes are not meaningful as of both June 2019 and December 2018 . The firm’s maximum exposure to adverse changes in the value of these interests is the carrying value of $ 134 2019 and $133 million as of December 2018 .

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Note 12. Variable Interest Entities A variable interest in a VIE is an investment (e.g., debt or equity) or other interest (e.g., derivatives or loans and lending commitments) that will absorb portions of the VIE’s expected losses and/or receive portions of the VIE’s expected residual returns. The firm’s variable interests in VIEs include senior and subordinated debt; loans and lending commitments; limited and general partnership interests; preferred and common equity; derivatives that may include foreign currency, equity and/or credit risk; guarantees; and certain of the fees the firm receives from investment funds. Certain interest rate, foreign currency and credit derivatives the firm enters into with VIEs are not variable interests because they create, rather than absorb, risk. VIEs generally finance the purchase of assets by issuing debt and equity securities that are either collateralized by or indexed to the assets held by the VIE. The debt and equity securities issued by a VIE may include tranches of varying levels of subordination. The firm’s involvement with VIEs includes securitization of financial assets, as described in Note 11, and investments in and loans to other types of VIEs, as described below. See Note 11 for further information about securitization activities, including the definition of beneficial interests. See Note 3 for the firm’s consolidation policies, including the definition of a VIE. VIE Consolidation Analysis The enterprise with a controlling financial interest in a VIE is known as the primary beneficiary and consolidates the VIE. The firm determines whether it is the primary beneficiary of a VIE by performing an analysis that principally considers: • Which variable interest holder has the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance; • Which variable interest holder has the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE; • The VIE’s purpose and design, including the risks the VIE was designed to create and pass through to its variable interest holders; • The VIE’s capital structure; • The terms between the VIE and its variable interest holders and other parties involved with the VIE; and • Related-party relationships. The firm reassesses its evaluation of whether an entity is a VIE when certain reconsideration events occur. The firm reassesses its determination of whether it is the primary beneficiary of a VIE on an ongoing basis based on current facts and circumstances. VIE Activities The firm is principally involved with VIEs through the following business activities: Mortgage-Backed VIEs. Real Estate, Credit- and Power-Related and Other Investing VIEs. Corporate Debt and Other Asset-Backed VIEs. Principal-Protected Note VIEs. Investments in Funds. Nonconsolidated VIEs The table below presents a summary of the nonconsolidated VIEs in which the firm holds variable interests. As of $ in millions June 2019 December 2018 Total nonconsolidated VIEs Assets in VIEs $ 116,224 $ 118,186 Carrying value of variable interests — assets $ 8,953 $ 9,543 Carrying value of variable interests — liabilities $ 573 $ 478 Maximum exposure to loss: Retained interests $ 2,780 $ 3,280 Purchased interests 746 983 Commitments and guarantees 3,021 2,745 Derivatives 8,647 8,975 Loans and investments 4,989 4,728 Total maximum exposure to loss $ 20,183 $ 20,711 In the table above: • The nature of the firm’s variable interests is described in the rows under maximum exposure to loss. • The firm’s exposure to the obligations of VIEs is generally limited to its interests in these entities. In certain instances, the firm provides guarantees, including derivative guarantees, to VIEs or holders of variable interests in VIEs. • The maximum exposure to loss excludes the benefit of offsetting financial instruments that are held to mitigate the risks associated with these variable interests. • The maximum exposure to loss from retained interests, purchased interests, and loans and investments is the carrying value of these interests. • The maximum exposure to loss from commitments and guarantees, and derivatives is the notional amount, which does not represent anticipated losses and has not been reduced by unrealized losses. As a result, the maximum exposure to loss exceeds liabilities recorded for commitments and guarantees, and derivatives. The table below disaggregates, by principal business activity, the information for nonconsolidated VIEs included in the summary table above.

Property, leasehold improvements and equipment included $5.80 billion as of June 2019 and $5.57 billion as of December 2018 that the firm uses in connection with its operations, and $678 million as of June 2019 and $896 million as of December 2018 of foreclosed real estate primarily related to PCI loans. The remainder is held by investment entities, including VIEs, consolidated by the firm. Substantially all property and equipment is depreciated on a straight-line basis over the useful life of the asset. Leasehold improvements are amortized on a straight-line basis over the shorter of the useful life of the improvement or the term of the lease. Capitalized costs of software developed or obtained for internal use are amortized on a straight-line basis over three years. The firm tests property, leasehold improvements and equipment for impairment whenever events or changes in circumstances suggest that an asset’s or asset group’s carrying value may not be fully recoverable. To the extent the carrying value of an asset or asset group exceeds the projected undiscounted cash flows expected to result from the use and eventual disposal of the asset or asset group, the firm determines the asset or asset group is impaired and records an impairment equal to the difference between the estimated fair value and the carrying value of the asset or asset group. In addition, the firm will recognize an impairment prior to the sale of an asset or asset group if the carrying value of the asset or asset group exceeds its estimated fair value. During each of the three and six months ended June 2019 and June 2018, such impairments were not material to the firm’s results of operations or financial condition.

Had these securities been included in the firm’s fair value hierarchy, U.S. government obligations would have been classified in level 1 and substantially all securities backed by real estate would have been classified in level 2 of the fair value hierarchy as of both June 2019 and December 2018. • The gross unrealized gains were $ 136 • Held-to-maturity securities in an unrealized loss position are periodically reviewed for other-than-temporary impairment. The firm considers various factors, including market conditions, changes in issuer credit ratings, severity and duration of the unrealized losses, and the intent and ability to hold the security until recovery to determine if the securities are other-than-temporarily impaired. There were no such impairments during each of the three and six months ended June 2019 and June 2018. Goodwill and Identifiable Intangible Assets Goodwill. As of $ in millions June 2019 December 2018 Investment Banking: Financial Advisory $ 98 $ 98 Underwriting 183 183 Institutional Client Services: FICC Client Execution 269 269 Equities client execution 2,404 2,403 Securities services 105 105 Investing & Lending 91 91 Investment Management 622 609 Total $3,772 $3,758 Goodwill is the cost of acquired companies in excess of the fair value of net assets, including identifiable intangible assets, at the acquisition date. Goodwill is assessed for impairment annually in the fourth quarter or more frequently if events occur or circumstances change that indicate an impairment may exist. When assessing goodwill for impairment, first, qualitative factors are assessed to determine whether it is more likely than not that the estimated fair value of a reporting unit is less than its estimated carrying value. If the results of the qualitative assessment are not conclusive, a quantitative goodwill test is performed. The quantitative goodwill test compares the estimated fair value of each reporting unit with its estimated net book value (including goodwill and identifiable intangible assets). If the reporting unit’s estimated fair value exceeds its estimated net book value, goodwill is not impaired. An impairment is recognized if the estimated fair value of a reporting unit is less than its estimated net book value. To estimate the fair value of each reporting unit, a relative value technique is used because the firm believes market participants would use this technique to value the firm’s reporting units. The relative value technique applies observable price-to-earnings price-to-book In the fourth quarter of 2018, the firm assessed goodwill for impairment for each of its reporting units by performing a qualitative assessment. Multiple factors were assessed with respect to each of the firm’s reporting units to determine whether it was more likely than not that the estimated fair value of any of these reporting units was less than its estimated carrying value. The qualitative assessment also considered changes since the prior quantitative tests. As a result of the qualitative assessment, the firm determined that it was more likely than not that the estimated fair value of each of the reporting units exceeded its respective carrying value. Therefore, the firm determined that goodwill for each reporting unit was not impaired and that a quantitative goodwill test was not required. There were no events or changes in circumstances during the six months ended June 2019 that would indicate that it was more likely than not that the estimated fair value of each of the reporting units did not exceed its respective estimated carrying value as of June 2019.

In addition, the firm will recognize an impairment prior to the sale of an asset or asset group if the carrying value of the asset or asset group exceeds its estimated fair value. There were no such impairments during each of the three and six months ended June 2019 and June 2018 .

These commitments are presented net of amounts syndicated to third parties. The total commitment amount does not necessarily reflect actual future cash flows because the firm may syndicate all or substantial additional portions of these commitments. In addition, commitments can expire unused or be reduced or cancelled at the counterparty’s request. The table below presents information about lending commitments.

Commercial Lending. Sumitomo Mitsui Financial Group, Inc. (SMFG) provides the firm with credit loss protection on certain approved loan commitments (primarily investment-grade commercial lending commitments). The notional amount of such loan commitments was $10.26 billion as of June 2019 and $15.52 billion as of December 2018. The credit loss protection on loan commitments provided by SMFG is generally limited to 95% of the first loss the firm realizes on such commitments, up to a maximum of approximately $950 million. In addition, subject to the satisfaction of certain conditions, upon the firm’s request, SMFG will provide protection for 70% of additional losses on such commitments, up to a maximum of $750 million, of which $550 million of protection had been provided as of both June 2019 and December 2018. The firm also uses other financial instruments to mitigate credit risks related to certain commitments not covered by SMFG. These instruments primarily include credit default swaps that reference the same or similar underlying instrument or entity, or credit default swaps that reference a market index. Warehouse Financing. Collateralized Agreement Commitments/ Collateralized Financing Commitments Collateralized agreement commitments includes forward starting resale and securities borrowing agreements, and collateralized financing commitments includes forward starting repurchase and secured lending agreements that settle at a future date, generally within three business days.

Investment commitments also included approximately $750 million as of June 2019, related to the firm’s commitment to acquire United Capital Financial Partners, Inc. This acquisition was completed in July 2019. Contingencies Legal Proceedings. Certain Mortgage-Related Contingencies. Based on the large number of defaults in residential mortgages, including those sold or securitized by the firm, there is a potential for repurchase claims. However, the firm is not in a position to make a meaningful estimate of that exposure at this time. The firm’s exposure to claims for repurchase of residential mortgage loans based on alleged breaches of representations will depend on a number of factors, such as the extent to which these claims are made within the statute of limitations, taking into consideration the agreements to toll the statute of limitations the firm entered into with trustees representing certain trusts. Other Contingencies. In connection with the settlement agreement with the Residential Mortgage-Backed Securities Working Group of the U.S. Financial Fraud Enforcement Task Force, the firm agreed to provide $1.80 billion in consumer relief by January 2021. As of June 2019, approximately $1.40 billion of such relief was provided. This relief was provided in the form of principal forgiveness for underwater homeowners and distressed borrowers; financing for construction, rehabilitation and preservation of affordable housing; and support for debt restructuring, foreclosure prevention and housing quality improvement programs, as well as land banks.

See the tables in “Commitments” above for a summary of the firm’s commitments. • The carrying value for derivatives included derivative assets of $1.65 billion as of June 2019 and $1.48 billion as of December 2018, and derivative liabilities of $6.26 billion as of June 2019 and $5.59 billion as of December 2018. Derivative Guarantees. The firm enters into various derivatives that meet the definition of a guarantee under U.S. GAAP, including​​​​​​​ written equity and commodity put options, written currency contracts and interest rate caps, floors and swaptions. Disclosures about derivatives are not required if they may be cash settled and the firm has no basis to conclude it is probable that the counterparties held the underlying instruments at inception of the contract. The firm has concluded that these conditions have been met for certain large, internationally active commercial and investment bank counterparties, central clearing counterparties, hedge funds and certain other counterparties. Derivatives are accounted for at fair value and therefore the carrying value is considered the best indication of payment/performance risk for individual contracts. However, the carrying values in the table above exclude the effect of counterparty and cash collateral netting. Securities Lending Indemnifications. Other Financial Guarantees. Guarantees of Securities Issued by Trusts. The firm effectively provides for the full and unconditional guarantee of the securities issued by these entities. Timely payment by the firm of amounts due to these entities under the guarantee, borrowing, preferred stock and related contractual arrangements will be sufficient to cover payments due on the securities issued by these entities. Management believes that it is unlikely that any circumstances will occur, such as nonperformance on the part of paying agents or other service providers, that would make it necessary for the firm to make payments related to these entities other than those required under the terms of the guarantee, borrowing, preferred stock and related contractual arrangements and in connection with certain expenses incurred by these entities. Indemnities and Guarantees of Service Providers. The firm may also be liable to some clients or other parties for losses arising from its custodial role or caused by acts or omissions of third-party service providers, including sub-custodians In connection with the firm’s prime brokerage and clearing businesses, the firm agrees to clear and settle on behalf of its clients the transactions entered into by them with other brokerage firms. The firm’s obligations in respect of such transactions are secured by the assets in the client’s account, as well as any proceeds received from the transactions cleared and settled by the firm on behalf of the client. In connection with joint venture investments, the firm may issue loan guarantees under which it may be liable in the event of fraud, misappropriation, environmental liabilities and certain other matters involving the borrower. The firm is unable to develop an estimate of the maximum payout under these guarantees and indemnifications. However, management believes that it is unlikely the firm will have to make any material payments under these arrangements, and no material liabilities related to these guarantees and indemnifications have been recognized in the consolidated statements of financial condition as of both June 2019 and December 2018. Other Representations, Warranties and Indemnifications. In addition, the firm may provide indemnifications to some counterparties to protect them in the event additional taxes are owed or payments are withheld, due either to a change in or an adverse application of certain non-U.S. These indemnifications generally are standard contractual terms and are entered into in the ordinary course of business. Generally, there are no stated or notional amounts included in these indemnifications, and the contingencies triggering the obligation to indemnify are not expected to occur. The firm is unable to develop an estimate of the maximum payout under these guarantees and indemnifications. However, management believes that it is unlikely the firm will have to make any material payments under these arrangements, and no material liabilities related to these arrangements have been recognized in the consolidated statements of financial condition as of both June 2019 and December 2018. Guarantees of Subsidiaries. Group Inc. guarantees many of the obligations of its other consolidated subsidiaries on a transaction-by-transaction

Regulation and Capital Adequacy	Note 20. Regulation and Capital Adequacy The FRB is the primary regulator of Group Inc., a bank holding company (BHC) under the U.S. Bank Holding Company Act of 1956 and a financial holding company under amendments to this Act. As a BHC, the firm is subject to consolidated regulatory capital requirements which are calculated in accordance with the regulations of the FRB (Capital Framework). The capital requirements are expressed as risk-based capital and leverage ratios that compare measures of regulatory capital to risk-weighted assets (RWAs), average assets and off-balance-sheet Capital Framework The regulations under the Capital Framework are largely based on the Basel Committee on Banking Supervision’s (Basel Committee) capital framework for strengthening international capital standards (Basel III) and also implement certain provisions of the Dodd-Frank Act. Under the Capital Framework, the firm is an “Advanced approach” banking organization and has been designated as a global systemically important bank (G-SIB). The capital requirements calculated in accordance with the Capital Framework include the minimum risk-based capital and leverage ratios. In addition, the risk-based capital requirements include the capital conservation buffer, countercyclical capital buffer and the G-SIB The firm calculates its CET1 capital, Tier 1 capital and Total capital ratios in accordance with (i) the Standardized approach and market risk rules set out in the Capital Framework (together, the Standardized Capital Rules) and (ii) the Advanced approach and market risk rules set out in the Capital Framework (together, the Basel III Advanced Rules). The lower of each risk-based capital ratio calculated in (i) and (ii) is the ratio against which the firm’s compliance with its risk-based capital requirements is assessed. Under the Capital Framework, the firm is also subject to leverage requirements which consist of a minimum Tier 1 leverage ratio and a minimum supplementary leverage ratio (SLR), as well as the SLR buffer.

As of June 2019 December 2018 Risk-based capital requirements CET1 capital ratio 9.5% 8.3% Tier 1 capital ratio 11.0% 9.8% Total capital ratio 13.0% 11.8% Leverage requirements Tier 1 leverage ratio 4.0% 4.0% SLR 5.0% 5.0% In the table above: • As of June 2019, the CET1 capital ratio requirement included a minimum of 4.5%, the Tier 1 capital ratio requirement included a minimum of 6.0%, and the Total capital ratio requirement included a minimum of 8.0%. The requirements also included the capital conservation buffer of 2.5%, the G-SIB • As of December 2018, the CET1 capital ratio requirement included a minimum of 4.5%, the Tier 1 capital ratio requirement included a minimum of 6.0%, and the Total capital ratio requirement included a minimum of 8.0%. The requirements also included the 75% phase-in phase-in G-SIB • The capital conservation buffer, countercyclical capital buffer and G-SIB surcharge phased in ratably from January 1, 2016 through January 1, 2019. • The G-SIB G-SIB G-SIB. • The Tier 1 leverage ratio requirement is a minimum of 4%. The SLR requirement of 5% as of both June 2019 and December 2018 includes a minimum of 3% and a 2% buffer applicable to G-SIBs.

Credit Risk Credit RWAs are calculated based on measures of exposure, which are then risk weighted under the Standardized Capital Rules and Basel III Advanced Rules: • The Standardized Capital Rules apply prescribed risk-weights, which depend largely on the type of counterparty. The exposure measure for derivatives and securities financing transactions are based on specific formulas which take certain factors into consideration. • Under the Basel III Advanced Rules, the firm computes risk-weights for wholesale and retail credit exposures in accordance with the Advanced Internal Ratings-Based approach. The exposure measures for derivatives and securities financing transactions are computed utilizing internal models. • For both Standardized and Basel III Advanced credit RWAs, the risk-weights for securitizations and equities are based on specific required formulaic approaches. Market Risk RWAs for market risk in accordance with the Standardized Capital Rules and the Basel III Advanced Rules are generally consistent. Market RWAs are calculated based on measures of exposure which include the following: • Value-at-Risk For both risk management purposes and regulatory capital calculations the firm uses a single VaR model which captures risks including those related to interest rates, equity prices, currency rates and commodity prices. However, VaR used for regulatory capital requirements (regulatory VaR) differs from risk management VaR due to different time horizons and confidence levels ( 10 one-day The firm’s positional losses observed on a single day did not exceed its 99% one-day one-day • Stressed VaR is the potential loss in value of inventory positions, as well as certain other financial assets and financial liabilities, during a period of significant market stress; • Incremental risk is the potential loss in value of non-securitized one-year • Comprehensive risk is the potential loss in value, due to price risk and defaults, within the firm’s credit correlation positions; and • Specific risk is the risk of loss on a position that could result from factors other than broad market movements, including event risk, default risk and idiosyncratic risk. The standardized measurement method is used to determine specific risk RWAs, by applying supervisory defined risk-weighting factors after applicable netting is performed.

Basel III Advanced Credit RWAs as of June 2019 increased by $20.60 billion compared with December 2018, primarily reflecting increases in commitments, guarantees and loans, principally due to an increase in lending activity, and an increase in other RWAs, principally due to an increase in corporate debt exposures, and the recognition of operating lease right-of-use assets upon adoption of ASU No. 2016-02. These increases were partially offset by a decrease in securities financing transactions, principally due to reduced exposures. Basel III Advanced Market RWAs as of June 2019 decreased by $12.57 billion compared with December 2018, primarily reflecting decreases in specific risk, principally due to reduced exposures and decreases in incremental risk, as a result of reduced exposures and changes in risk measurements. Basel III Advanced Operational RWAs as of June 2019 decreased by $7.61​​​​​​​ billion compared with December 2018, reflecting the removal of certain events incorporated within the firm’s risk-based model based on the passage of time. Year Ended December 2018. Basel III Advanced Credit RWAs as of December 2018 decreased by $44.57 billion compared with December 2017. Beginning in the fourth quarter of 2018, the firm’s default experience was incorporated into the determination of probability of default, which resulted in a decrease in credit RWAs, primarily in commitments, guarantees and loans and derivatives. Basel III Advanced Market RWAs as of December 2018 decreased by $12.28 billion compared with December 2017, primarily reflecting a decrease in specific risk on positions for which the firm obtained increased transparency into the underliers and as a result utilized a modeled approach to calculate RWAs. Regulatory Capital Ratios. Under the regulatory framework for prompt corrective action applicable to GS Bank USA, in order to meet the quantitative requirements for being a “well-capitalized” depository institution, GS Bank USA must also meet the “well-capitalized” requirements in the table below. GS Bank USA’s capital levels and prompt corrective action classification are also subject to qualitative judgments by the regulators about components of capital, risk weightings and other factors. Failure to comply with these capital requirements, including a breach of the buffers described above, could result in restrictions being imposed by GS Bank USA’s regulators. Similar to the firm, GS Bank USA is required to calculate each of the CET1 capital, Tier 1 capital and Total capital ratios in accordance with both the Standardized Capital Rules and Basel III Advanced Rules. The lower of each risk-based capital ratio calculated in accordance with the Standardized Capital Rules and Basel III Advanced Rules is the ratio against which GS Bank USA’s compliance with its risk-based capital requirements is assessed. The table below presents GS Bank USA’s risk-based capital, leverage and “well-capitalized” requirements. As of June 2019 December 2018 “Well-capitalized” Risk-based capital requirements CET1 capital ratio 7.0% 6.4% 6.5% Tier 1 capital ratio 8.5% 7.9% 8.0% Total capital ratio 10.5% 9.9% 10.0% Leverage requirements Tier 1 leverage ratio 4.0% 4.0% 5.0% SLR 3.0% 3.0% 6.0% In the table above: • As of June 2019, the CET1 capital ratio requirement included a minimum of 4.5%, the Tier 1 capital ratio requirement included a minimum of 6.0%, and the Total capital ratio requirement included a minimum of 8.0%. The requirements also included the capital conservation buffer of 2.5% and the countercyclical capital buffer, which the FRB has set to zero percent. • As of December 2018, the CET1 capital ratio requirement included a minimum of 4.5%, the Tier 1 capital ratio requirement included a minimum of 6.0%, and the Total capital ratio requirement included a minimum of 8.0%. The requirements also included the 75% phase-in • The “well-capitalized” requirements were the binding requirements for risk-based capital ratios as of December 2018 and were the binding requirements for leverage ratios as of both June 2019 and December 2018.

The firm’s principal non-U.S. Other. Restrictions on Payments Group Inc. may be limited in its ability to access capital held at certain subsidiaries as a result of regulatory, tax or other constraints. These limitations include provisions of applicable law and regulations and other regulatory restrictions that limit the ability of those subsidiaries to declare and pay dividends without prior regulatory approval (e.g., dividends that may be paid by GS Bank USA are limited to the lesser of the amounts calculated under a recent earnings test and an undivided profits test) even if the relevant subsidiary would satisfy the equity capital requirements applicable to it after giving effect to the dividend. For example, the FRB, the FDIC and the New York State Department of Financial Services have authority to prohibit or to limit the payment of dividends by the banking organizations they supervise (including GS Bank USA) if, in the regulator’s opinion, payment of a dividend would constitute an unsafe or unsound practice in the light of the financial condition of the banking organization. In addition, subsidiaries not subject to separate regulatory capital requirements may hold capital to satisfy local tax and legal guidelines, rating agency requirements (for entities with assigned credit ratings) or internal policies, including policies concerning the minimum amount of capital a subsidiary should hold based on its underlying level of risk. Group Inc.’s equity investment in subsidiaries was $93.33 billion as of June 2019 and $90.22 billion as of December 2018, of which Group Inc. was required to maintain $57.44 billion as of June 2019 and $52.92 billion as of December 2018, of minimum equity capital in its regulated subsidiaries in order to satisfy the regulatory requirements of such subsidiaries.

Transactions with Affiliated Funds	Note 22. Transactions with Affiliated Funds The firm has formed numerous nonconsolidated investment funds with third-party investors. As the firm generally acts as the investment manager for these funds, it is entitled to receive management fees and, in certain cases, advisory fees or incentive fees from these funds. Additionally, the firm invests alongside the third-party investors in certain funds. The tables below present information about affiliated funds.

Management fees waived were $ million for both the three months ended June and June , $ million for the six months ended June and $ million for the six months ended June . The Volcker Rule restricts the firm from providing financial support to covered funds (as defined in the rule) after the expiration of the conformance period. As a general matter, in the ordinary course of business, the firm does not expect to provide additional voluntary financial support to any covered funds, but may choose to do so with respect to funds that are not subject to the Volcker Rule; however, in the event that such support is provided, the amount is not expected to be material. The firm had outstanding guarantees, as permitted under the Volcker Rule, on behalf of its funds of $89 million as of June 2019 and $154 million as of December 2018. Substantially all of these amounts relate to a guarantee that the firm has voluntarily provided in connection with a financing agreement with a third-party lender executed by one of the firm’s real estate funds that is not covered by the Volcker Rule. As of both June 2019 and December 2018, except as noted above, the firm has not provided any additional financial support to its affiliated funds. In addition, in the ordinary course of business, the firm may also engage in other activities with its affiliated funds including, among others, securities lending, trade execution, market-making, custody, and acquisition and bridge financing. See Note 18 for the firm’s investment commitments related to these funds.

Income Tax Disclosure [Abstract]
Income Taxes	Note 24. Income Taxes Provision for Income Taxes Income taxes are provided for using the asset and liability method under which deferred tax assets and liabilities are recognized for temporary differences between the financial reporting and tax bases of assets and liabilities. The firm reports interest expense related to income tax matters in provision for taxes and income tax penalties in other expenses. Deferred Income Taxes Deferred income taxes reflect the net tax effects of temporary differences between the financial reporting and tax bases of assets and liabilities. These temporary differences result in taxable or deductible amounts in future years and are measured using the tax rates and laws that will be in effect when such differences are expected to reverse. Valuation allowances are established to reduce deferred tax assets to the amount that more likely than not will be realized and primarily relate to the ability to utilize losses in various tax jurisdictions. Tax assets are included in other assets and tax liabilities are included in other liabilities. Unrecognized Tax Benefits The firm recognizes tax positions in the consolidated financial statements only when it is more likely than not that the position will be sustained on examination by the relevant taxing authority based on the technical merits of the position. A position that meets this standard is measured at the largest amount of benefit that will more likely than not be realized on settlement. A liability is established for differences between positions taken in a tax return and amounts recognized in the consolidated financial statements. Regulatory Tax Examinations The firm is subject to examination by the U.S. Internal Revenue Service (IRS) and other taxing authorities in jurisdictions where the firm has significant business operations, such as the United Kingdom, Japan, Hong Kong and various states, such as New York. The tax years under examination vary by jurisdiction. The firm does not expect completion of these audits to have a material impact on the firm’s financial condition, but it may be material to operating results for a particular period, depending, in part, on the operating results for that period. The table below presents the earliest tax years that remain subject to examination by major jurisdiction. Jurisdiction As of June 2019 U.S. Federal 2011 New York State and City 2011 United Kingdom 2014 Japan 2014 Hong Kong 2013 U.S. Federal examinations of 2011 and 2012 began in 2013. The firm has been accepted into the Compliance Assurance Process program by the IRS for each of the tax years from 2013 through 2019. This program allows the firm to work with the IRS to identify and resolve potential U.S. Federal tax issues before the filing of tax returns. The 2013 through 2017 tax years remain subject to post-filing review. New York State and City examinations (excluding GS Bank USA) of 2011 through 2014 began in 2017. New York State and City examinations for GS Bank USA have been completed through 2014. All years including and subsequent to the years in the table above remain open to examination by the taxing authorities. The firm believes that the liability for unrecognized tax benefits it has established is adequate in relation to the potential for additional assessments.

Segment Reporting [Abstract]
Business Segments	Note 25. Business Segments The firm reports its activities in the following four business segments: Investment Banking, Institutional Client Services, Investing & Lending and Investment Management. Basis of Presentation In reporting segments, certain of the firm’s business lines have been aggregated where they have similar economic characteristics and are similar in each of the following areas: (i) the nature of the services they provide, (ii) their methods of distribution, (iii) the types of clients they serve and (iv) the regulatory environments in which they operate. The cost drivers of the firm taken as a whole, compensation, headcount and levels of business activity, are broadly similar in each of the firm’s business segments. Compensation and benefits expenses in the firm’s segments reflect, among other factors, the overall performance of the firm, as well as the performance of individual businesses. Consequently, pre-tax The firm allocates assets (including allocations of global core liquid assets and cash, secured client financing and other assets), revenues and expenses among the four business segments. Due to the integrated nature of these segments, estimates and judgments are made in allocating certain assets, revenues and expenses. The allocation process is based on the manner in which management currently views the performance of the segments. Management believes that this allocation provides a reasonable representation of each segment’s contribution to consolidated pre-tax The table below presents net revenues, provision for credit losses, operating expenses and pre-tax Three Months Six Months Ended June $ in millions 2019 2018 2019 2018 Investment Banking Financial Advisory $ 776 $ 804 $ 1,663 $ 1,390 Equity underwriting 482 489 753 899 Debt underwriting 605 752 1,257 1,549 Total Underwriting 1,087 1,241 2,010 2,448 Total net revenues 1,863 2,045 3,673 3,838 Operating expenses 1,049 1,210 2,051 2,220 Pre-tax $ 814 $ 835 $ 1,622 $ 1,618 Institutional Client Services FICC Client Execution $ 1,469 $1,679 $ 3,308 $ 3,753 Equities client execution 772 691 1,454 1,753 Commissions and fees 777 763 1,491 1,580 Securities services 458 437 828 869 Total Equities 2,007 1,891 3,773 4,202 Total net revenues 3,476 3,570 7,081 7,955 Operating expenses 2,584 2,552 5,236 5,704 Pre-tax $ 892 $1,018 $ 1,845 $ 2,251 Investing & Lending Equity securities $ 1,541 $1,281 $ 2,388 $ 2,350 Debt securities and loans 989 897 1,979 1,959 Total net revenues 2,530 2,178 4,367 4,309 Provision for credit losses 214 234 438 278 Operating expenses 1,190 953 2,076 1,983 Pre-tax $ 1,126 $ 991 $ 1,853 $ 2,048 Investment Management Management and other fees $ 1,395 $1,345 $ 2,727 $ 2,691 Incentive fees 44 316 102 529 Transaction revenues 153 182 318 394 Total net revenues 1,592 1,843 3,147 3,614 Operating expenses 1,297 1,411 2,621 2,836 Pre-tax $ 295 $ 432 $ 526 $ 778 Total net revenues $ 9,461 $9,636 $ 18,268 $19,716 Provision for credit losses 214 234 438 278 Total operating expenses 6,120 6,126 11,984 12,743 Total pre-tax $ 3,127 $3,276 $ 5,846 $ 6,695 In the table above: • Revenues and expenses directly associated with each segment are included in determining pre-tax • Net revenues in the firm’s segments include allocations of interest income and expense to specific securities, commodities and other positions in relation to the cash generated by, or funding requirements of, such positions.

Credit Concentrations

Risks and Uncertainties [Abstract]
Credit Concentrations	Note 26. Credit Concentrations The firm’s concentrations of credit risk arise from its market making, client facilitation, investing, underwriting, lending and collateralized transactions, and cash management activities, and may be impacted by changes in economic, industry or political factors. These activities expose the firm to many different industries and counterparties, and may also subject the firm to a concentration of credit risk to a particular central bank, counterparty, borrower or issuer, including sovereign issuers, or to a particular clearing house or exchange. The firm seeks to mitigate credit risk by actively monitoring exposures and obtaining collateral from counterparties as deemed appropriate. The firm measures and monitors its credit exposure based on amounts owed to the firm after taking into account risk mitigants that management considers when determining credit risk. Such risk mitigants include netting and collateral arrangements and economic hedges, such as credit derivatives, futures and forward contracts.

Legal Proceedings	Note 27. Legal Proceedings The firm is involved in a number of judicial, regulatory and arbitration proceedings (including those described below) concerning matters arising in connection with the conduct of the firm’s businesses. Many of these proceedings are in early stages, and many of these cases seek an indeterminate amount of damages. Under ASC 450, an event is “reasonably possible” if “the chance of the future event or events occurring is more than remote but less than likely” and an event is “remote” if “the chance of the future event or events occurring is slight.” Thus, references to the upper end of the range of reasonably possible loss for cases in which the firm is able to estimate a range of reasonably possible loss mean the upper end of the range of loss for cases for which the firm believes the risk of loss is more than slight. With respect to matters described below for which management has been able to estimate a range of reasonably possible loss where (i) actual or potential plaintiffs have claimed an amount of money damages, (ii) the firm is being, or threatened to be, sued by purchasers in a securities offering and is not being indemnified by a party that the firm believes will pay the full amount of any judgment, or (iii) the purchasers are demanding that the firm repurchase securities, management has estimated the upper end of the range of reasonably possible loss as being equal to (a) in the case of (i), the amount of money damages claimed, (b) in the case of (ii), the difference between the initial sales price of the securities that the firm sold in such offering and the estimated lowest subsequent price of such securities prior to the action being commenced and (c) in the case of (iii), the price that purchasers paid for the securities less the estimated value, if any, as of June 2019 of the relevant securities, in each of cases (i), (ii) and (iii), taking into account any other factors believed to be relevant to the particular matter or matters of that type. As of the date hereof, the firm has estimated the upper end of the range of reasonably possible aggregate loss for such matters and for any other matters described below where management has been able to estimate a range of reasonably possible aggregate loss to be approximately $2.6 billion in excess of the aggregate reserves for such matters. Management is generally unable to estimate a range of reasonably possible loss for matters other than those included in the estimate above, including where (i) actual or potential plaintiffs have not claimed an amount of money damages, except in those instances where management can otherwise determine an appropriate amount, (ii) matters are in early stages, (iii) matters relate to regulatory investigations or reviews, except in those instances where management can otherwise determine an appropriate amount, (iv) there is uncertainty as to the likelihood of a class being certified or the ultimate size of the class, (v) there is uncertainty as to the outcome of pending appeals or motions, (vi) there are significant factual issues to be resolved, and/or (vii) there are novel legal issues presented. For example, the firm’s potential liabilities with respect to the investigations and reviews described below in “Regulatory Investigations and Reviews and Related Litigation” generally are not included in management’s estimate of reasonably possible loss. However, management does not believe, based on currently available information, that the outcomes of such other matters will have a material adverse effect on the firm’s financial condition, though the outcomes could be material to the firm’s operating results for any particular period, depending, in part, upon the operating results for such period. See Note 18 for further information about mortgage-related contingencies. 1Malaysia Development Berhad (1MDB)-Related Matters The firm has received subpoenas and requests for documents and information from various governmental and regulatory bodies and self-regulatory organizations as part of investigations and reviews relating to financing transactions and other matters involving 1MDB, a sovereign wealth fund in Malaysia. Subsidiaries of the firm acted as arrangers or purchasers of approximately $ 6.5 On November 1, 2018, the U.S. Department of Justice (DOJ) unsealed a criminal information and guilty plea by Tim Leissner, a former participating managing director of the firm, and an indictment against Ng Chong Hwa, a former managing director of the firm, and Low Taek Jho. Leissner pleaded guilty to a two-count criminal information charging him with conspiring to launder money and conspiring to violate the U.S. Foreign Corrupt Practices Act’s (FCPA) anti-bribery and internal accounting controls provisions. Low and Ng were charged in a three-count indictment with conspiring to launder money and conspiring to violate the FCPA’s anti-bribery provisions. On August 28, 2018, Leissner’s guilty plea was accepted by the U.S. District Court for the Eastern District of New York and Leissner was adjudicated guilty on both counts. Ng was also charged in this indictment with conspiring to violate the FCPA’s internal accounting controls provisions. The charging documents state, among other things, that Leissner and Ng participated in a conspiracy to misappropriate proceeds of the 1MDB offerings for themselves and to pay bribes to various government officials to obtain and retain 1MDB business for the firm. The plea and charging documents indicate that Leissner and Ng knowingly and willfully circumvented the firm’s system of internal accounting controls, in part by repeatedly lying to control personnel and internal committees that reviewed these offerings. The indictment of Ng and Low alleges that the firm’s system of internal accounting controls could be easily circumvented and that the firm’s business culture, particularly in Southeast Asia, at times prioritized consummation of deals ahead of the proper operation of its compliance functions. On May 6, 2019, Ng pleaded not guilty to the DOJ’s criminal charges. In addition, an unnamed participating managing director of the firm is alleged to have been aware of the bribery scheme and to have agreed not to disclose this information to the firm’s compliance and control personnel. That employee, who was identified as a co-conspirator, has been put on administrative leave. On December 17, 2018, the Attorney General of Malaysia filed criminal charges in Malaysia against Goldman Sachs International (GSI), as the arranger of three offerings of debt securities of 1MDB, aggregating approximately $6.5 billion in principal amount, for alleged disclosure deficiencies in the offering documents relating to, among other things, the use of proceeds for the debt securities, as well as against Goldman Sachs (Asia) LLC (GS Asia) and Goldman Sachs (Singapore) PTE (GS Singapore). Criminal charges have also been filed against Leissner, Low, Ng and Jasmine Loo Ai Swan. In a related press release, the Attorney General of Malaysia indicated that prosecutors in Malaysia will seek criminal fines against the accused in excess of $2.7 billion plus the $600 million of fees received in connection with the debt offerings. The Malaysia Securities Commission issued notices to show cause against Goldman Sachs (Malaysia) Sdn Bhd (GS Malaysia) in December 2018 and March 2019 that (i) allege possible violations of Malaysian securities laws and (ii) indicate that the Malaysia Securities Commission is considering whether to revoke GS Malaysia’s license to conduct corporate finance and fund management activities in Malaysia. The firm has received multiple demands, beginning in November 2018, from alleged shareholders under Section 220 of the Delaware General Corporation Law for books and records relating to, among other things, the firm’s involvement with 1MDB and the firm’s compliance procedures. On February 19, 2019, a purported shareholder derivative action relating to 1MDB was filed in the U.S. District Court for the Southern District of New York against Group Inc. and the directors at the time and a former chairman and chief executive officer of the firm. The amended complaint filed on July 12, 2019, which seeks unspecified damages, disgorgement and injunctive relief, alleges breaches of fiduciary duties, including in connection with alleged insider trading by certain current and former directors, unjust enrichment and violations of the anti-fraud provisions of the Exchange Act, including in connection with Group Inc.’s common stock repurchases and solicitation of proxies. Beginning in March 2019, the firm has also received demands from alleged shareholders to investigate and pursue claims against certain current and former directors and executive officers based on their oversight and public disclosures regarding 1MDB and related internal controls. On November 21, 2018, a summons with notice was filed in New York Supreme Court, New York County, by International Petroleum Investment Company, which guaranteed certain debt securities issued by 1MDB, and its subsidiary Aabar Investments PJS. The summons with notice makes unspecified claims relating to 1MDB and seeks unspecified compensatory and punitive damages and other relief against Group Inc., GSI, GS Asia, GS Singapore, GS Malaysia, Leissner, Ng, and an employee of the firm, as well as individuals (who are not employees of the firm) formerly associated with the plaintiffs. On December 20, 2018, a putative securities class action lawsuit was filed in the U.S. District Court for the Southern District of New York against Group Inc. and certain current and former officers of the firm alleging violations of the anti-fraud provisions of the Exchange Act with respect to Group Inc.’s disclosures concerning 1MDB and seeking unspecified damages. The firm is cooperating with the DOJ and all other governmental and regulatory investigations relating to 1MDB and is engaged in discussions with various governmental and regulatory authorities. Proceedings by the DOJ or other governmental or regulatory authorities could result in the imposition of significant fines, penalties and other sanctions against the firm, including restrictions on the firm’s activities. Mortgage-Related Matters Beginning in April 2010, a number of purported securities law class actions were filed in the U.S. District Court for the Southern District of New York challenging the adequacy of Group Inc.’s public disclosure of, among other things, the firm’s activities in the collateralized debt obligation market, and the firm’s conflict of interest management. The consolidated amended complaint filed on July 25, 2011, which names as defendants Group Inc. and certain current and former officers and employees of Group Inc. and its affiliates, generally alleges violations of Sections 10(b) and 20(a) of the Exchange Act and seeks unspecified damages. The defendants have moved for summary judgment. On December 11, 2018, the Second Circuit Court of Appeals granted the defendants’ petition for interlocutory review of the district court’s August 14, 2018 grant of class certification. On January 23, 2019, the district court stayed proceedings in the district court pending the appellate court’s decision. Beginning on February 15, 2019, a summons with notice and a complaint were filed against Goldman Sachs Mortgage Company and GS Mortgage Securities Corp. by U.S. Bank National Association, as trustee for two residential mortgage-backed securitization trusts that issued $1.7 billion of securities, and the cases are pending in the U.S. District Court for the Southern District of New York. The summons with notice and complaint generally allege that mortgage loans in the trusts failed to conform to applicable representations and warranties and seek specific performance or, alternatively, compensatory damages and other relief. The firm has received subpoenas or requests for information from, and is engaged in discussions with, certain regulators and law enforcement agencies with which it has not entered into settlement agreements as part of inquiries or investigations relating to mortgage-related matters. Director Compensation-Related Litigation On May 9, 2017, Group Inc. and certain of its current and former directors were named as defendants in a purported direct and derivative shareholder action in the Court of Chancery of the State of Delaware (a similar purported derivative action, filed in June 2015, alleging excessive director compensation over the period 2012 to 2014 was voluntarily dismissed without prejudice in December 2016). The new complaint alleges that excessive compensation has been paid to the non-employee director defendants since 2015, and that certain disclosures in connection with soliciting shareholder approval of the stock incentive plans were deficient. The complaint asserts claims for breaches of fiduciary duties and seeks, among other things, rescission or in some cases rescissory damages, disgorgement, and shareholder votes on several matters. On October 23, 2018, the court declined to approve the parties’ proposed settlement. On May 31, 2019, the court dismissed the disclosure-related claims, but permitted the non-employee director compensation claim to proceed. Currencies-Related Litigation GS&Co. and Group Inc. are among the defendants named in putative class actions filed in the U.S. District Court for the Southern District of New York beginning in September 2016 on behalf of putative indirect purchasers of foreign exchange instruments. The consolidated amended complaint, filed on June 30, 2017, generally alleged a conspiracy to manipulate the foreign currency exchange markets and asserted claims under federal and state antitrust laws and state consumer protection laws. On March 15, 2018, the court granted defendants’ motion to dismiss in its entirety, and on October 25, 2018, plaintiffs’ motion for leave to replead was denied as to the claim under federal antitrust law and granted as to the claims under state antitrust and consumer protection laws.

GS&Co. and Group Inc. are among the defendants named in an action filed in the U.S. District Court for the Southern District of New York on November 7, 2018 by certain direct purchasers of foreign exchange instruments that opted out of a class settlement reached with, among others, GS&Co. and Group Inc. The second amended complaint, filed on June 11, 2019, generally alleges that the defendants violated federal antitrust and state common laws in connection with an alleged conspiracy to manipulate the foreign currency exchange markets and seeks declaratory and injunctive relief, as well as unspecified amounts of compensatory, punitive, treble and other damages. Defendants moved to dismiss on July 25, 2019. GS&Co. and Group Inc. are among the defendants named in two putative class actions filed in the district court of the Central District in Israel on behalf of direct purchasers of foreign exchange instruments. The complaints, filed on September 11, 2018 and September 29, 2018, respectively, generally allege a conspiracy to manipulate prices of foreign exchange instruments. The second putative class action also asserts claims based on misuse of the “last look” features of foreign exchange trading systems. Financial Advisory Services Group Inc. and certain of its affiliates are from time to time parties to various civil litigation and arbitration proceedings and other disputes with clients and third parties relating to the firm’s financial advisory activities. These claims generally seek, among other things, compensatory damages and, in some cases, punitive damages, and in certain cases allege that the firm did not appropriately disclose or deal with conflicts of interest.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation These consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) and include the accounts of Group Inc. and all other entities in which the firm has a controlling financial interest. Intercompany transactions and balances have been eliminated.
Consolidation, Policy	Consolidation The firm consolidates entities in which the firm has a controlling financial interest. The firm determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a variable interest entity (VIE). Voting Interest Entities. Variable Interest Entities. Equity-Method Investments. in-substance In general, the firm accounts for investments acquired after the fair value option became available, at fair value. In certain cases, the firm applies the equity method of accounting to new investments that are strategic in nature or closely related to the firm’s principal business activities, when the firm has a significant degree of involvement in the cash flows or operations of the investee or when cost-benefit considerations are less significant. See Note 13 for further information about equity-method investments. Investment Funds.
Use of Estimates	Use of Estimates Preparation of these consolidated financial statements requires management to make certain estimates and assumptions, the most important of which relate to fair value measurements, accounting for goodwill and identifiable intangible assets, discretionary compensation accruals, the allowance for credit losses on loans receivable and lending commitments held for investment, provisions for losses that may arise from litigation and regulatory proceedings (including governmental investigations), and provisions for losses that may arise from tax audits. These estimates and assumptions are based on the best available information but actual results could be materially different.
Revenue Recognition, Policy	Revenue Recognition Financial Assets and Financial Liabilities at Fair Value. Revenue from Contracts with Clients. 2014-09, Revenues from contracts with clients subject to this ASU represent approximately 45% of total non-interest revenues for each of the three and six months ended June 2019 Investment Banking Advisory. Non-refundable Expenses associated with financial advisory assignments are recognized when incurred and are included in other expenses. Client reimbursements for such expenses are included in investment banking revenues. Underwriting. Expenses associated with underwriting assignments are generally deferred until the related revenue is recognized or the assignment is otherwise concluded. Such expenses are included in other expenses. Investment Management The firm earns management fees and incentive fees for investment management services, which are included in investment management revenues. The firm makes payments to brokers and advisors related to the placement of the firm’s investment funds (distribution fees), which are included in brokerage, clearing, exchange and distribution fees. Management Fees. month-end Distribution fees paid by the firm are calculated based on either a percentage of the management fee, the investment fund’s net asset value or the committed capital. Such fees are included in brokerage, clearing, exchange and distribution fees. Incentive Fees. Incentive fees earned from a fund or separately managed account are recognized when it is probable that a significant reversal of such fees will not occur, which is generally when such fees are no longer subject to fluctuations in the market value of investments held by the fund or separately managed account. Therefore, incentive fees recognized during the period may relate to performance obligations satisfied in previous periods. Commissions and Fees The firm earns commissions and fees from executing and clearing client transactions on stock, options and futures markets, as well as over-the-counter Remaining Performance Obligations Remaining performance obligations are services that the firm has committed to perform in the future in connection with its contracts with clients. The firm’s remaining performance obligations are generally related to its financial advisory assignments and certain investment management activities. Revenues associated with remaining performance obligations relating to financial advisory assignments cannot be determined until the outcome of the transaction. For the firm’s investment management activities, where fees are calculated based on the net asset value of the fund or separately managed account, future revenues associated with such remaining performance obligations cannot be determined as such fees are subject to fluctuations in the market value of investments held by the fund or separately managed account. The firm is able to determine the future revenues associated with management fees calculated based on committed capital. As of June 2019, substantially all future net revenues associated with such remaining performance obligations will be recognized through 2024. Annual revenues associated with such performance obligations average less than $250 million through 2024.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of financial assets are accounted for as sales when the firm has relinquished control over the assets transferred. For transfers of financial assets accounted for as sales, any gains or losses are recognized in net revenues. Assets or liabilities that arise from the firm’s continuing involvement with transferred financial assets are initially recognized at fair value. For transfers of financial assets that are not accounted for as sales, the assets are generally included in financial instruments owned and the transfer is accounted for as a collateralized financing, with the related interest expense recognized over the life of the transaction. See Note 10 for further information about transfers of financial assets accounted for as collateralized financings and Note 11 for further information about transfers of financial assets accounted for as sales.
Cash and Cash Equivalents, Policy	Cash and Cash Equivalents The firm defines cash equivalents as highly liquid overnight deposits held in the ordinary course of business. Cash and cash equivalents included cash and due from banks of $12.29 billion as of June 2019 and $10.66 billion as of December 2018. Cash and cash equivalents also included interest-bearing deposits with banks of $78.80 billion as of June 2019 and $119.89 billion as of December 2018. The firm segregates cash for regulatory and other purposes related to client activity. Cash and cash equivalents segregated for regulatory and other purposes were $23.14 billion as of both June 2019 and December 2018. In addition, the firm segregates securities for regulatory and other purposes related to client activity. See Note 10 for further information about segregated securities.
Customer and Other Receivables, Policy	Customer and Other Receivables Customer and other receivables included receivables from customers and counterparties of $56.59 billion as of June 2019 and $53.81 billion as of December 2018, and receivables from brokers, dealers and clearing organizations of $27.33 billion as of June 2019 and $25.50 billion as of December 2018. Such receivables primarily consist of customer margin loans, receivables resulting from unsettled transactions, collateral posted in connection with certain derivative transactions and certain transfers of assets accounted for as secured loans rather than purchases at fair value. Substantially all of these receivables are accounted for at amortized cost net of estimated uncollectible amounts. Certain of the firm’s customer and other receivables are accounted for at fair value under the fair value option, with changes in fair value generally included in market making revenues. See Note 8 for further information about customer and other receivables accounted for at fair value under the fair value option. In addition, the firm’s customer and other receivables included $3.34 billion as of June 2019 and $3.83 billion as of December 2018 of loans held for sale accounted for at the lower of cost or fair value. See Note 5 for an overview of the firm’s fair value measurement policies. As of both June 2019 and December 2018, the carrying value of receivables not accounted for at fair value generally approximated fair value. As these receivables are not accounted for at fair value, they are not included in the firm’s fair value hierarchy in Notes 5 through 8. Had these receivables been included in the firm’s fair value hierarchy, substantially all would have been classified in level 2 as of both June 2019 and December 2018. Interest on customer and other receivables is recognized over the life of the transaction and included in interest income.
Customer and Other Payables, Policy	Customer and Other Payables Customer and other payables included payables to customers and counterparties of $177.18 billion as of June 2019 and $173.99 billion as of December 2018, and payables to brokers, dealers and clearing organizations of $8.10 billion as of June 2019 and $6.24 billion as of December 2018. Such payables primarily consist of customer credit balances related to the firm’s prime brokerage activities. Customer and other payables are accounted for at cost plus accrued interest, which generally approximates fair value. As these payables are not accounted for at fair value, they are not included in the firm’s fair value hierarchy in Notes 5 through 8. Had these payables been included in the firm’s fair value hierarchy, substantially all would have been classified in level 2 as of both June 2019 and December 2018. Interest on customer and other payables is recognized over the life of the transaction and included in interest expense.
Offsetting Assets and Liabilities, Policy	Offsetting Assets and Liabilities To reduce credit exposures on derivatives and securities financing transactions, the firm may enter into master netting agreements or similar arrangements (collectively, netting agreements) with counterparties that permit it to offset receivables and payables with such counterparties. A netting agreement is a contract with a counterparty that permits net settlement of multiple transactions with that counterparty, including upon the exercise of termination rights by a non-defaulting non-defaulting Derivatives are reported on a net-by-counterparty net-by-counterparty In the consolidated statements of financial condition, derivatives are reported net of cash collateral received and posted under enforceable credit support agreements, when transacted under an enforceable netting agreement. In the consolidated statements of financial condition, resale and repurchase agreements, and securities borrowed and loaned, are not reported net of the related cash and securities received or posted as collateral. See Note 10 for further information about collateral received and pledged, including rights to deliver or repledge collateral. See Notes 7 and 10 for further information about offsetting assets and liabilities.
Share-based Compensation, Policies	Share-based Compensation The cost of employee services received in exchange for a share-based award is generally measured based on the grant-date fair value of the award. Share-based awards that do not require future service (i.e., vested awards, including awards granted to retirement-eligible employees) are expensed immediately. Share-based awards that require future service are amortized over the relevant service period. Forfeitures are recorded when they occur. Cash dividend equivalents paid on outstanding restricted stock units (RSUs) are charged to retained earnings. If RSUs that require future service are forfeited, the related dividend equivalents originally charged to retained earnings are reclassified to compensation expense in the period in which forfeiture occurs. The firm generally issues new shares of common stock upon delivery of share-based awards. In certain cases, primarily related to conflicted employment (as outlined in the applicable award agreements), the firm may cash settle share-based compensation awards accounted for as equity instruments. For these awards, whose terms allow for cash settlement, additional paid-in

Recent Accounting Developments	Recent Accounting Developments Revenue from Contracts with Customers (ASC 606). 2014-09. The firm adopted this ASU in January 2018 under a modified retrospective approach. As a result of adopting this ASU, the firm, among other things, delays recognition of non-refundable The firm also prospectively changed the presentation of certain costs from a net presentation within revenues to a gross basis, and vice versa. Beginning in 2018, certain underwriting expenses, which were netted against investment banking revenues, and certain distribution fees, which were netted against investment management revenues, are presented gross as operating expenses. Costs incurred in connection with certain soft-dollar arrangements, which were presented gross as operating expenses, are presented net within commissions and fees. The cumulative effect of adopting this ASU as of January 1, 2018 was a decrease to retained earnings of $53 million (net of tax). Leases (ASC 842). 2016-02, right-of-use right-of-use The firm adopted this ASU in January 2019 under a modified retrospective approach. Upon adoption, in accordance with the ASU, the firm elected to not reassess the lease classification or initial direct costs of existing leases, and to not reassess whether existing contracts contain a lease. In addition, the firm has elected to account for each contract’s lease and non-lease Measurement of Credit Losses on Financial Instruments (ASC 326). 2016-13, Under CECL, the allowance for losses for financial assets that are measured at amortized cost reflects management’s estimate of credit losses over the remaining expected life of such assets. Expected credit losses for newly recognized financial assets, as well as changes to expected credit losses during the period, would be recognized in earnings. For certain purchased financial assets with deterioration in credit quality since origination, an initial allowance would be recorded for expected credit losses and recognized as an increase to the purchase price rather than as an expense. The ASU eliminates the existing accounting guidance for Purchased Credit Impaired (PCI) loans. The ASU is effective for the firm in January 2020 under a modified retrospective approach with early adoption permitted. The firm plans to adopt this ASU on January 1, 2020. Expected credit losses, including losses on off-balance-sheet exposures, such as lending commitments, will be measured based on historical experience, current conditions and forecasts that affect the collectability of the reported amount. The firm has substantially completed development of credit loss models for significant loan portfolios and is in the process of testing these models and validating data inputs, while continuing to develop the policies, systems and controls that will be required to implement CECL. Based on the work completed to date, the current loan portfolio and the weighted average of a range of current forecasts of future economic conditions, the firm estimates that the allowance for credit losses will increase by approximately $600 million to $800 million when CECL is adopted. The estimated increase is driven by the fact that the allowance will cover expected credit losses over the full expected life of the loan portfolios and will also take into account forecasts of expected future economic conditions. This increased allowance will not impact the firm’s realized losses in these loan portfolios. In addition, an allowance will be recorded for certain purchased loans with deterioration in credit quality since origination with a corresponding increase to their gross carrying value. Ultimately, the extent of the impact of adoption of this ASU on the firm’s consolidated financial statements may vary and will depend on, among other things, the economic environment, the completion of the firm’s models, policies and other management judgments, and the size and type of loan portfolios held by the firm on the date of adoption. Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (ASC 220). In February 2018 , the FASB issued ASU No. 2018 - 02 , “Income Statement — Reporting Comprehensive Income (Topic 220) — Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” This ASU permits a reporting entity to reclassify the income tax effects of the Tax Cuts and Jobs Act (Tax Legislation) on items within accumulated other comprehensive income to retained earnings. The firm adopted this ASU in January 2019 and did not elect to reclassify the income tax effects of Tax Legislation from accumulated other comprehensive income to retained earnings. Therefore, the adoption of the ASU did not have an impact on the firm’s consolidated financial statements.
Fair Value Measurements, Policy	Fair Value Measurements The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Financial assets are marked to bid prices and financial liabilities are marked to offer prices. Fair value measurements do not include transaction costs. The firm measures certain financial assets and financial liabilities as a portfolio (i.e., based on its net exposure to market and/or credit risks). The best evidence of fair value is a quoted price in an active market. If quoted prices in active markets are not available, fair value is determined by reference to prices for similar instruments, quoted prices or recent transactions in less active markets, or internally developed models that primarily use market-based or independently sourced inputs, including, but not limited to, interest rates, volatilities, equity or debt prices, foreign exchange rates, commodity prices, credit spreads and funding spreads (i.e., the spread or difference between the interest rate at which a borrower could finance a given financial instrument relative to a benchmark interest rate). U.S. GAAP has a three-level hierarchy for disclosure of fair value measurements. This hierarchy prioritizes inputs to the valuation techniques used to measure fair value, giving the highest priority to level 1 inputs and the lowest priority to level 3 inputs. A financial instrument’s level in this hierarchy is based on the lowest level of input that is significant to its fair value measurement. In evaluating the significance of a valuation input, the firm considers, among other factors, a portfolio’s net risk exposure to that input. The fair value hierarchy is as follows: Level 1. Level 2. Level 3. Cash instruments include U.S. government and agency obligations, non-U.S. non-derivative Level 1 Cash Instruments Level 1 cash instruments include certain money market instruments, U.S. government obligations, most non-U.S. The firm defines active markets for equity instruments based on the average daily trading volume both in absolute terms and relative to the market capitalization for the instrument. The firm defines active markets for debt instruments based on both the average daily trading volume and the number of days with trading activity. Level 2 Cash Instruments Level 2 cash instruments include most money market instruments, most government agency obligations, certain non-U.S. Valuations of level 2 cash instruments can be verified to quoted prices, recent trading activity for identical or similar instruments, broker or dealer quotations or alternative pricing sources with reasonable levels of price transparency. Consideration is given to the nature of the quotations (e.g., indicative or firm) and the relationship of recent market activity to the prices provided from alternative pricing sources. Valuation adjustments are typically made to level 2 cash instruments (i) if the cash instrument is subject to transfer restrictions and/or (ii) for other premiums and liquidity discounts that a market participant would require to arrive at fair value. Valuation adjustments are generally based on market evidence. Level 3 Cash Instruments Level 3 cash instruments have one or more significant valuation inputs that are not observable. Absent evidence to the contrary, level 3 cash instruments are initially valued at transaction price, which is considered to be the best initial estimate of fair value. Subsequently, the firm uses other methodologies to determine fair value, which vary based on the type of instrument. Valuation inputs and assumptions are changed when corroborated by substantive observable evidence, including values realized on sales. Valuation Techniques and Significant Inputs of Level 3 Cash Instruments Valuation techniques of level 3 cash instruments vary by instrument, but are generally based on discounted cash flow techniques. The valuation techniques and the nature of significant inputs used to determine the fair values of each type of level 3 cash instrument are described below: Loans and Securities Backed by Commercial Real Estate. • Market yields implied by transactions of similar or related assets and/or current levels and changes in market indices, such as the CMBX (an index that tracks the performance of commercial mortgage bonds); • Transaction prices in both the underlying collateral and instruments with the same or similar underlying collateral; • A measure of expected future cash flows in a default scenario (recovery rates) implied by the value of the underlying collateral, which is mainly driven by current performance of the underlying collateral, capitalization rates and multiples. Recovery rates are expressed as a percentage of notional or face value of the instrument and reflect the benefit of credit enhancements on certain instruments; and • Timing of expected future cash flows (duration) which, in certain cases, may incorporate the impact of other unobservable inputs (e.g., prepayment speeds). Loans and Securities Backed by Residential Real Estate. • Market yields implied by transactions of similar or related assets; • Transaction prices in both the underlying collateral and instruments with the same or similar underlying collateral; • Cumulative loss expectations, driven by default rates, home price projections, residential property liquidation timelines, related costs and subsequent recoveries; and • Duration, driven by underlying loan prepayment speeds and residential property liquidation timelines. Corporate Debt Instruments. • Market yields implied by transactions of similar or related assets and/or current levels and trends of market indices, such as the CDX (an index that tracks the performance of corporate credit); • Current performance and recovery assumptions and, where the firm uses credit default swaps to value the related cash instrument, the cost of borrowing the underlying reference obligation; and • Duration. Equity Securities. • Industry multiples (primarily EBITDA multiples) and public comparables; • Transactions in similar instruments; • Discounted cash flow techniques; and • Third-party appraisals. The firm also considers changes in the outlook for the relevant industry and financial performance of the issuer as compared to projected performance. Significant inputs include: • Market and transaction multiples; • Discount rates and capitalization rates; and • For equity securities with debt-like features, market yields implied by transactions of similar or related assets, current performance and recovery assumptions, and duration. Other Cash Instruments. non-U.S. • Market yields implied by transactions of similar or related assets and/or current levels and trends of market indices; • Current performance and recovery assumptions and, where the firm uses credit default swaps to value the related cash instrument, the cost of borrowing the underlying reference obligation; and • Duration. Investments in Funds at Net Asset Value Per Share Cash instruments at fair value include investments in funds that are measured at NAV of the investment fund. The firm uses NAV to measure the fair value of its fund investments when (i) the fund investment does not have a readily determinable fair value and (ii) the NAV of the investment fund is calculated in a manner consistent with the measurement principles of investment company accounting, including measurement of the investments at fair value. Derivatives are reported on a net-by-counterparty Valuation Techniques for Derivatives The firm’s level 2 and level 3 derivatives are valued using derivative pricing models (e.g., discounted cash flow models, correlation models, and models that incorporate option pricing methodologies, such as Monte Carlo simulations). Price transparency of derivatives can generally be characterized by product type, as described below. • Interest Rate. 10-year 2-year • Credit. • Currency. • Commodity. • Equity. Liquidity is essential to observability of all product types. If transaction volumes decline, previously transparent prices and other inputs may become unobservable. Conversely, even highly structured products may at times have trading volumes large enough to provide observability of prices and other inputs. See Note 5 for an overview of the firm’s fair value measurement policies.
Hedge Accounting, Policy	• Transfers between levels of the fair value hierarchy are reported at the beginning of the reporting period in which they occur. If a cash instrument asset or liability was transferred to level 3 during a reporting period, its entire gain or loss for the period is classified in level 3. Hedge Accounting The firm applies hedge accounting for (i) certain interest rate swaps used to manage the interest rate exposure of certain fixed-rate unsecured long-term and short-term borrowings and certain fixed-rate certificates of deposit and (ii) certain foreign currency forward contracts and foreign currency-denominated debt used to manage foreign currency exposures on the firm’s net investment in certain non-U.S. To qualify for hedge accounting, the hedging instrument must be highly effective at reducing the risk from the exposure being hedged. Additionally, the firm must formally document the hedging relationship at inception and assess the hedging relationship at least on a quarterly basis to ensure the hedging instrument continues to be highly effective over the life of the hedging relationship. Fair Value Hedges The firm designates certain interest rate swaps as fair value hedges of certain fixed-rate unsecured long-term and short-term debt and fixed-rate certificates of deposit. These interest rate swaps hedge changes in fair value attributable to the designated benchmark interest rate (e.g., London Interbank Offered Rate (LIBOR) or Overnight Index Swap Rate), effectively converting a substantial portion of fixed-rate obligations into floating-rate obligations. The firm applies a statistical method that utilizes regression analysis when assessing the effectiveness of its fair value hedging relationships in achieving offsetting changes in the fair values of the hedging instrument and the risk being hedged (i.e., interest rate risk). An interest rate swap is considered highly effective in offsetting changes in fair value attributable to changes in the hedged risk when the regression analysis results in a coefficient of determination of 80 80 125 For qualifying fair value hedges, gains or losses on derivatives are included in interest expense. The change in fair value of the hedged item attributable to the risk being hedged is reported as an adjustment to its carrying value (hedging adjustment) and is also included in interest expense. When a derivative is no longer designated as a hedge, any remaining difference between the carrying value and par value of the hedged item is amortized to interest expense over the remaining life of the hedged item using the effective interest method. See Note 23 for further information about interest income and interest expense. Net Investment Hedges The firm seeks to reduce the impact of fluctuations in foreign exchange rates on its net investments in certain non-U.S.
Fair Value Option, Policy	Fair Value Option Other Financial Assets and Financial Liabilities at Fair Value In addition to cash and derivative instruments included in financial instruments owned and financial instruments sold, but not yet purchased, the firm accounts for certain of its other financial assets and financial liabilities at fair value, substantially all under the fair value option. The primary reasons for electing the fair value option are to: • Reflect economic events in earnings on a timely basis; • Mitigate volatility in earnings from using different measurement attributes (e.g., transfers of financial instruments owned accounted for as financings are recorded at fair value, whereas the related secured financing would be recorded on an accrual basis absent electing the fair value option); and • Address simplification and cost-benefit considerations (e.g., accounting for hybrid financial instruments at fair value in their entirety versus bifurcation of embedded derivatives and hedge accounting for debt hosts). Hybrid financial instruments are instruments that contain bifurcatable embedded derivatives and do not require settlement by physical delivery of nonfinancial assets (e.g., physical commodities). If the firm elects to bifurcate the embedded derivative from the associated debt, the derivative is accounted for at fair value and the host contract is accounted for at amortized cost, adjusted for the effective portion of any fair value hedges. If the firm does not elect to bifurcate, the entire hybrid financial instrument is accounted for at fair value under the fair value option.
Loans Receivable, Policy	Loans Receivable Loans receivable consists of loans held for investment that are accounted for at amortized cost net of allowance for loan losses. Interest on loans receivable is recognized over the life of the loan and is recorded on an accrual basis. PCI Loans Loans receivable includes PCI loans, which represent acquired loans or pools of loans with evidence of credit deterioration subsequent to their origination and where it is probable, at acquisition, that the firm will not be able to collect all contractually required payments. Loans acquired within the same reporting period, which have at least two common risk characteristics, one of which relates to their credit risk, are eligible to be pooled together and considered a single unit of account. PCI loans are initially recorded at the acquisition price and the difference between the acquisition price and the expected cash flows (accretable yield) is recognized as interest income over the life of such loans or pools of loans on an effective yield method. Expected cash flows on PCI loans are determined using various inputs and assumptions, including default rates, loss severities, recoveries, amount and timing of prepayments and other macroeconomic indicators. Impaired Loans. In certain circumstances, the firm may also modify the original terms of a loan agreement by granting a concession to a borrower experiencing financial difficulty. Such modifications are considered troubled debt restructurings and typically include interest rate reductions, payment extensions, and modification of loan covenants. Loans modified in a troubled debt restructuring are considered impaired and are subject to specific loan-level reserves. Allowance for Credit Losses The firm’s allowance for credit losses consists of the allowance for losses on loans and lending commitments. The firm’s allowance for loan losses consists of specific loan-level reserves, portfolio level reserves and reserves on PCI loans, as described below: • Specific loan-level reserves are determined on loans (excluding PCI loans) that exhibit credit quality weakness and are therefore individually evaluated for impairment. • Portfolio level reserves are determined on loans (excluding PCI loans) not evaluated for specific loan-level reserves by aggregating groups of loans with similar risk characteristics and estimating the probable loss inherent in the portfolio. • Reserves on PCI loans are recorded when it is determined that the expected cash flows, which are reassessed on a quarterly basis, will be lower than those used to establish the current effective yield for such loans or pools of loans. If the expected cash flows are determined to be significantly higher than those used to establish the current effective yield, such increases are initially recognized as a reduction to any previously recorded allowances for loan losses and any remaining increases are recognized as interest income prospectively over the life of the loan or pools of loans as an increase to the effective yield. The allowance for loan losses is determined using various risk factors, including industry default and loss data, current macroeconomic indicators, borrower’s capacity to meet its financial obligations, borrower’s country of risk, loan seniority and collateral type. In addition, for loans backed by real estate, risk factors include loan to value ratio, debt service ratio and home price index. Risk factors for consumer loans include FICO credit scores and delinquency status. Management’s estimate of loan losses entails judgment about loan collectability at the reporting dates, and there are uncertainties inherent in those judgments. While management uses the best information available to determine this estimate, future adjustments to the allowance may be necessary based on, among other things, changes in the economic environment or variances between actual results and the original assumptions used. Loans are charged off against the allowance for loan losses when deemed to be uncollectible. The firm also records an allowance for losses on lending commitments that are held for investment and accounted for on an accrual basis. Such allowance is determined using the same methodology as the allowance for loan losses, while also taking into consideration the probability of drawdowns or funding, and is included in other liabilities.
Collateralized Agreements and Financings, Policy	Collateralized agreements and financings are presented on a net-by-counterparty Even though repurchase and resale agreements (including “repos- and reverses-to-maturity”) The firm has elected to apply the fair value option to substantially all other secured financings because the use of fair value eliminates non-economic volatility in earnings that would arise from using different measurement attributes. See Note 8 for further information about other secured financings that are accounted for at fair value. • Short-term other secured financings includes financings maturing within one year of the financial statement date and financings that are redeemable within one year of the financial statement date at the option of the holder. • Long-term other secured financings that are repayable prior to maturity at the option of the firm are reflected at their contractual maturity dates. • Long-term other secured financings that are redeemable prior to maturity at the option of the holder are reflected at the earliest dates such options become exercisable.
Securitization Activities, Policy	The firm accounts for a securitization as a sale when it has relinquished control over the transferred financial assets. Prior to securitization, the firm generally accounts for assets pending transfer at fair value and therefore does not typically recognize significant gains or losses upon the transfer of assets. Net revenues from underwriting activities are recognized in connection with the sales of the underlying beneficial interests to investors. For transfers of financial assets that are not accounted for as sales, the assets remain in financial instruments owned and the transfer is accounted for as a collateralized financing, with the related interest expense recognized over the life of the transaction. See Note 10 for further information about collateralized financings and Note 23 for further information about interest expense.
Consolidation, Variable Interest Entity, Policy	VIE Consolidation Analysis The enterprise with a controlling financial interest in a VIE is known as the primary beneficiary and consolidates the VIE. The firm determines whether it is the primary beneficiary of a VIE by performing an analysis that principally considers: • Which variable interest holder has the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance; • Which variable interest holder has the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE; • The VIE’s purpose and design, including the risks the VIE was designed to create and pass through to its variable interest holders; • The VIE’s capital structure; • The terms between the VIE and its variable interest holders and other parties involved with the VIE; and • Related-party relationships. The firm reassesses its evaluation of whether an entity is a VIE when certain reconsideration events occur. The firm reassesses its determination of whether it is the primary beneficiary of a VIE on an ongoing basis based on current facts and circumstances.
Property, Plant and Equipment, Policy	Substantially all property and equipment is depreciated on a straight-line basis over the useful life of the asset. Leasehold improvements are amortized on a straight-line basis over the shorter of the useful life of the improvement or the term of the lease. Capitalized costs of software developed or obtained for internal use are amortized on a straight-line basis over three years. • Held-to-maturity securities in an unrealized loss position are periodically reviewed for other-than-temporary impairment. The firm considers various factors, including market conditions, changes in issuer credit ratings, severity and duration of the unrealized losses, and the intent and ability to hold the security until recovery to determine if the securities are other-than-temporarily impaired. There were no such impairments during each of the three and six months ended June 2019 and June 2018.
Goodwill and Intangible Assets, Policy	Goodwill is the cost of acquired companies in excess of the fair value of net assets, including identifiable intangible assets, at the acquisition date. Goodwill is assessed for impairment annually in the fourth quarter or more frequently if events occur or circumstances change that indicate an impairment may exist. When assessing goodwill for impairment, first, qualitative factors are assessed to determine whether it is more likely than not that the estimated fair value of a reporting unit is less than its estimated carrying value. If the results of the qualitative assessment are not conclusive, a quantitative goodwill test is performed. Substantially all of the firm’s identifiable intangible assets have finite useful lives and are amortized over their estimated useful lives generally using the straight-line method.
Impairments, Policy	The firm tests property, leasehold improvements and equipment for impairment whenever events or changes in circumstances suggest that an asset’s or asset group’s carrying value may not be fully recoverable. To the extent the carrying value of an asset or asset group exceeds the projected undiscounted cash flows expected to result from the use and eventual disposal of the asset or asset group, the firm determines the asset or asset group is impaired and records an impairment equal to the difference between the estimated fair value and the carrying value of the asset or asset group. In addition, the firm will recognize an impairment prior to the sale of an asset or asset group if the carrying value of the asset or asset group exceeds its estimated fair value.
Property, Plant and Equipment, Operating Lease Policy	For leases where the firm has ceased using the space and management has concluded that the firm will not derive any future economic benefits, the firm records an impairment of right-of-use
Deposits, Policy	The firm’s savings and demand deposits are recorded based on the amount of cash received plus accrued interest
Debt, Policy	Unsecured short-term borrowings includes the portion of unsecured long-term borrowings maturing within one year of the financial statement date and unsecured long-term borrowings that are redeemable within one year of the financial statement date at the option of the holder. • Unsecured long-term borrowings maturing within one year of the financial statement date and unsecured long-term borrowings that are redeemable within one year of the financial statement date at the option of the holder are excluded as they are included in unsecured short-term borrowings. • Unsecured long-term borrowings that are repayable prior to maturity at the option of the firm are reflected at their contractual maturity dates. • Unsecured long-term borrowings that are redeemable prior to maturity at the option of the holder are reflected at the earliest dates such options become exercisable.
Commitments to Extend Credit, Policy	Lending Commitments • Held for investment lending commitments are accounted for on an accrual basis. See Note 9 for further information about such commitments. • Held for sale lending commitments are accounted for at the lower of cost or fair value. • Gains or losses related to lending commitments at fair value, if any, are generally recorded net of any fees in other principal transactions. • Substantially all lending commitments relate to the firm’s Investing & Lending segment.
Derivative Guarantees, Policy	The firm enters into various derivatives that meet the definition of a guarantee under U.S. GAAP, including​​​​​​​ written equity and commodity put options, written currency contracts and interest rate caps, floors and swaptions. Disclosures about derivatives are not required if they may be cash settled and the firm has no basis to conclude it is probable that the counterparties held the underlying instruments at inception of the contract. The firm has concluded that these conditions have been met for certain large, internationally active commercial and investment bank counterparties, central clearing counterparties, hedge funds and certain other counterparties.
Earnings Per Share Policy	Basic
Interest Income and Interest Expense, Policy	Interest is recorded over the life of the instrument on an accrual basis based on contractual interest rates.
Income Tax, Policy	Provision for Income Taxes Income taxes are provided for using the asset and liability method under which deferred tax assets and liabilities are recognized for temporary differences between the financial reporting and tax bases of assets and liabilities. The firm reports interest expense related to income tax matters in provision for taxes and income tax penalties in other expenses. Deferred Income Taxes Deferred income taxes reflect the net tax effects of temporary differences between the financial reporting and tax bases of assets and liabilities. These temporary differences result in taxable or deductible amounts in future years and are measured using the tax rates and laws that will be in effect when such differences are expected to reverse. Valuation allowances are established to reduce deferred tax assets to the amount that more likely than not will be realized and primarily relate to the ability to utilize losses in various tax jurisdictions. Tax assets are included in other assets and tax liabilities are included in other liabilities. Unrecognized Tax Benefits The firm recognizes tax positions in the consolidated financial statements only when it is more likely than not that the position will be sustained on examination by the relevant taxing authority based on the technical merits of the position. A position that meets this standard is measured at the largest amount of benefit that will more likely than not be realized on settlement. A liability is established for differences between positions taken in a tax return and amounts recognized in the consolidated financial statements.
Business Segments, Policy	The firm allocates assets (including allocations of global core liquid assets and cash, secured client financing and other assets), revenues and expenses among the four business segments. Due to the integrated nature of these segments, estimates and judgments are made in allocating certain assets, revenues and expenses. The allocation process is based on the manner in which management currently views the performance of the segments. Management believes that this allocation provides a reasonable representation of each segment’s contribution to consolidated pre-tax

See Note 25 for net revenues, including net interest income, by product type for Investing & Lending, as well as the amount of net interest income included in Investing & Lending. • Gains/(losses) are not representative of the manner in which the firm manages its business activities because many of the firm’s market-making and client facilitation strategies utilize financial instruments across various product types. Accordingly, gains or losses in one product type frequently offset gains or losses in other product types. For example, most of the firm’s longer-term derivatives across product types are sensitive to changes in interest rates and may be economically hedged with interest rate swaps. Similarly, a significant portion of the firm’s cash instruments and derivatives across product types has exposure to foreign currencies and may be economically hedged with foreign currency contracts.

For example, the highest multiple for private equity securities is appropriate for valuing a specific private equity security but may not be appropriate for valuing any other private equity security. Accordingly, the ranges of inputs do not represent uncertainty in, or possible ranges of, fair value measurements of level 3 cash instruments. • Increases in yield, discount rate, capitalization rate, duration or cumulative loss rate used in the valuation of level 3 cash instruments would have resulted in a lower fair value measurement, while increases in recovery rate or multiples would have resulted in a higher fair value measurement as of both June 2019 and December 2018. Due to the distinctive nature of each level 3 cash instrument, the interrelationship of inputs is not necessarily uniform within each product type. • Loans and securities backed by commercial and residential real estate, corporate debt instruments and other cash instruments are valued using discounted cash flows, and equity securities are valued using market comparables and discounted cash flows. • The fair value of any one instrument may be determined using multiple valuation techniques. For example, market comparables and discounted cash flows may be used together to determine fair value. Therefore, the level 3 balance encompasses both of these techniques.

If a cash instrument asset or liability was transferred to level 3 during a reporting period, its entire gain or loss for the period is classified in level 3. • For level 3 cash instrument assets, increases are shown as positive amounts, while decreases are shown as negative amounts. For level 3 cash instrument liabilities, increases are shown as negative amounts, while decreases are shown as positive amounts. • Level 3 cash instruments are frequently economically hedged with level 1 and level 2 cash instruments and/or level 1, level 2 or level 3 derivatives. Accordingly, gains or losses that are classified in level 3 can be partially offset by gains or losses attributable to level 1 or level 2 cash instruments and/or level 1, level 2 or level 3 derivatives. As a result, gains or losses included in the level 3 rollforward below do not necessarily represent the overall impact on the firm’s results of operations, liquidity or capital resources.

In practice, simultaneous changes in assumptions might magnify or counteract the sensitivities disclosed above. • The constant prepayment rate is included only for positions for which it is a key assumption in the determination of fair value. • The discount rate for retained interests that relate to U.S. government agency-issued collateralized mortgage obligations does not include any credit loss. Expected credit loss assumptions are reflected in the discount rate for the remainder of retained interests.
