Accounting Policies [Abstract]
Significant Accounting Policies	Note 3. Significant Accounting Policies The firm’s significant accounting policies include when and how to measure the fair value of assets and liabilities, accounting for goodwill and identifiable intangible assets, and when to consolidate an entity. See Notes 5 through 8 for policies on fair value measurements, Note 13 for policies on goodwill and identifiable intangible assets, and below and Note 12 for policies on consolidation accounting. All other significant accounting policies are either described below or included in the following footnotes: Financial Instruments Owned and Financial Instruments Note 4 Fair Value Measurements Note 5 Cash Instruments Note 6 Derivatives and Hedging Activities Note 7 Fair Value Option Note 8 Loans Receivable Note 9 Collateralized Agreements and Financings Note 10 Securitization Activities Note 11 Variable Interest Entities Note 12 Other Assets Note 13 Deposits Note 14 Short-Term Borrowings Note 15 Long-Term Borrowings Note 16 Other Liabilities Note 17 Commitments, Contingencies and Guarantees Note 18 Shareholders’ Equity Note 19 Regulation and Capital Adequacy Note 20 Earnings Per Common Share Note 21 Transactions with Affiliated Funds Note 22 Interest Income and Interest Expense Note 23 Income Taxes Note 24 Business Segments Note 25 Credit Concentrations Note 26 Legal Proceedings Note 27 Employee Benefit Plans Note 28 Employee Incentive Plans Note 29 Parent Company Note 30 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. Voting interest entities are entities in which (i) the total equity investment at risk is sufficient to enable the entity to finance its activities independently and (ii) the equity holders have the power to direct the activities of the entity that most significantly impact its economic performance, the obligation to absorb the losses of the entity and the right to receive the residual returns of the entity. The usual condition for a controlling financial interest in a voting interest entity is ownership of a majority voting interest. If the firm has a controlling majority voting interest in a voting interest entity, the entity is consolidated. Variable Interest Entities. A VIE is an entity that lacks one or more of the characteristics of a voting interest entity. The firm has a controlling financial interest in a VIE when the firm has a variable interest or interests that provide it with (i) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. See Note 12 for further information about VIEs. Equity-Method Investments. When the firm does not have a controlling financial interest in an entity but can exert significant influence over the entity’s operating and financial policies, the investment is accounted for either (i) under the equity method of accounting or (ii) at fair value by electing the fair value option available under U.S. GAAP. Significant influence generally exists when the firm owns 20% to 50% of the entity’s common stock or 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. The firm has formed numerous investment funds with third-party investors. These funds are typically organized as limited partnerships or limited liability companies for which the firm acts as general partner or manager. Generally, the firm does not hold a majority of the economic interests in these funds. These funds are usually voting interest entities and generally are not consolidated because third-party investors typically have rights to terminate the funds or to remove the firm as general partner or manager. Investments in these funds are generally measured at net asset value (NAV) and are included in financial instruments owned. See Notes 6, 18 and 22 for further information about investments in funds. 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, 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. Financial instruments owned and financial instruments sold, but not yet purchased are recorded at fair value either under the fair value option or in accordance with other U.S. GAAP. In addition, the firm has elected to account for certain of its other financial assets and financial liabilities at fair value by electing the fair value option. 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. Fair value gains or losses are generally included in market making for positions in Institutional Client Services and other principal transactions for positions in Investing & Lending. See Notes 5 through 8 for further information about fair value measurements. Revenue from Contracts with Clients. Beginning in January 2018, the firm accounts for revenue earned from contracts with clients for services such as investment banking, investment management, and execution and clearing (contracts with clients) under ASU No. 2014-09, The firm’s net revenues from contracts with clients subject to this ASU represent approximately 50% of the firm’s total net revenues for 2018. This includes approximately 80% of the firm’s investment banking revenues, substantially all of the investment management revenues, and commissions and fees for 2018. See Note 25 for information about the firm’s net revenues by business segment. Investment Banking Advisory. Fees from financial advisory assignments are recognized in revenues when the services related to the underlying transaction are completed under the terms of the assignment. Beginning in January 2018, non-refundable non-refundable Beginning in January 2018, certain expenses associated with financial advisory assignments are recognized when incurred. Client reimbursements for such expenses are included in financial advisory revenues. Prior to January 2018, such expenses were deferred until the related revenue was recognized or the assignment was otherwise concluded and were presented net of client reimbursements. Underwriting. Fees from underwriting assignments are recognized in revenues upon completion of the underlying transaction based on the terms of the assignment. Certain expenses associated with underwriting assignments are deferred until the related revenue is recognized or the assignment is otherwise concluded. Beginning in January 2018, such expenses are presented as operating expenses. Prior to January 2018, such expenses were presented net within underwriting revenues. 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. Management fees for mutual funds are calculated as a percentage of daily net asset value and are received monthly. Management fees for hedge funds and separately managed accounts are calculated as a percentage of 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. Beginning in January 2018, the firm presents such fees in brokerage, clearing, exchange and distribution fees. Prior to January 2018, where the firm was considered an agent to the arrangement, such fees were presented on a net basis in investment management revenues. Incentive Fees. Incentive fees are calculated as a percentage of a fund’s or separately managed account’s return, or excess return above a specified benchmark or other performance target. Incentive fees are generally based on investment performance over a twelve-month period or over the life of a fund. Fees that are based on performance over a twelve-month period are subject to adjustment prior to the end of the measurement period. For fees that are based on investment performance over the life of the fund, future investment underperformance may require fees previously distributed to the firm to be returned to the fund. Beginning in January 2018, 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. Prior to January 2018, incentive fees were recognized only when all material contingencies were resolved. 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 Beginning in January 2018, third-party research costs incurred by the firm in connection with soft-dollar arrangements are presented net within commissions and fees. Prior to January 2018, such costs were presented in brokerage, clearing, exchange and distribution fees. 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 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 December 2018, substantially all of the firm’s future net revenues associated with 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 $10.66 billion as of December 2018 and $10.79 billion as of December 2017. Cash and cash equivalents also included interest-bearing deposits with banks of $119.89 billion as of December 2018 and $99.26 billion as of December 2017. 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 December 2018 and $18.44 billion as of December 2017. 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 $53.81 billion as of December 2018 and $60.11 billion as of December 2017, and receivables from brokers, dealers and clearing organizations of $25.50 billion as of December 2018 and $24.68 billion as of December 2017. 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 $3.83 billion as of December 2018 and $4.63 billion as of December 2017 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 December 2018 and December 2017, 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 December 2018 and December 2017. 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, beginning in January 2018, also includes 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. As of December 2018, the firm’s receivables from contracts with clients were $1.94 billion and contract assets were not material. Customer and Other Payables Customer and other payables included payables to customers and counterparties of $173.99 billion as of December 2018 and $171.50 billion as of December 2017, and payables to brokers, dealers and clearing organizations of $6.24 billion as of December 2018 and $6.67 billion as of December 2017. 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 December 2018 and December 2017. 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. Foreign Currency Translation Assets and liabilities denominated in non-U.S. non-U.S. Recent Accounting Developments Revenue from Contracts with Customers (ASC 606). In May 2014, the FASB issued ASU No. 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). In addition, net revenues and operating expenses were both higher by approximately $300 million for 2018, due to the changes in the presentation of certain costs from a net presentation within revenues to a gross basis. Recognition and Measurement of Financial Assets and Financial Liabilities (ASC 825). In January 2016, the FASB issued ASU No. 2016-01, In January 2016, the firm early adopted this ASU for the requirements related to DVA and reclassified the cumulative DVA, a gain of $305 million (net of tax), from retained earnings to accumulated other comprehensive loss. The adoption of the remaining provisions of the ASU in January 2018 did not have a material impact on the firm’s financial condition, results of operations or cash flows. Leases (ASC 842). In February 2016, the FASB issued ASU No. 2016-02, right-of-use right-of-use The firm adopted this ASU in January 2019 under a modified retrospective approach. The impact of adopting this ASU was a gross up of $1.77 billion on the firm’s consolidated statements of financial condition and an increase to retained earnings of $12 million (net of tax) as of January 1, 2019. Improvements to Employee Share-Based Payment Accounting (ASC 718). In March 2016, the FASB issued ASU No. 2016-09, paid-in The firm adopted the ASU in January 2017 and subsequent to the adoption, the tax effect related to the settlement of share-based awards is recognized in the statements of earnings rather than directly to additional paid-in In addition, the ASU modifies the classification of certain share-based payment activities within the statements of cash flows. Upon adoption, the firm reclassified amounts related to such activities within the consolidated statements of cash flows, on a retrospective basis. Measurement of Credit Losses on Financial Instruments (ASC 326). In June 2016, the FASB issued ASU No. 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 the financial 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 beginning in January 2019. The firm plans to adopt this ASU on January 1, 2020. Expected credit losses, including losses on off-balance-sheet The firm has substantially completed development of credit loss models for its significant loan portfolios and is in the process of validating data inputs to these models, while continuing to develop the policies, systems and controls that will be required to implement CECL. The firm currently expects to begin testing of these models in the first half of 2019. The firm currently expects that its allowance for credit losses will likely increase when CECL is adopted as the allowance will cover expected credit losses over the full expected life of the loan portfolios and will also take into account expected changes in future economic conditions. 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. The extent of the impact of adoption of this ASU on the firm’s financial condition, results of operations and cash flows will depend on, among other things, the economic environment, and the size and type of loan portfolios held by the firm on the date of adoption. Classification of Certain Cash Receipts and Cash Payments (ASC 230). In August 2016, the FASB issued ASU No. 2016-15, The firm adopted this ASU in January 2018 under a retrospective approach. The impact for 2017 was an increase of $485 million to net cash used for operating activities, a decrease of $477 million to net cash used for investing activities and an increase of $8 million to net cash provided by financing activities. The impact for 2016 was a decrease of $406 million to net cash provided by operating activities, an increase of $405 million to net cash provided by investing activities and an increase of $1 million to net cash provided by financing activities. Clarifying the Definition of a Business (ASC 805). In January 2017, the FASB issued ASU No. 2017-01, The firm adopted this ASU in January 2018 under a prospective approach. Adoption of the ASU did not have a material impact on the firm’s financial condition, results of operations or cash flows. The firm expects that fewer transactions will be treated as acquisitions (or disposals) of businesses as a result of adopting this ASU. Simplifying the Test for Goodwill Impairment (ASC 350). In January 2017, the FASB issued ASU No. 2017-04, The firm early adopted this ASU in the fourth quarter of 2017. Adoption of the ASU did not have a material impact on the results of the firm’s goodwill impairment test. Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets (ASC 610-20). In February 2017, the FASB issued ASU No. 2017-05, (Subtopic 610-20) — The firm adopted this ASU in January 2018 under a modified retrospective approach. Adoption of the ASU did not have an impact on the firm’s financial condition, results of operations or cash flows. Targeted Improvements to Accounting for Hedging Activities (ASC 815). In August 2017, the FASB issued ASU No. 2017-12, The firm early adopted this ASU in January 2018 under a modified retrospective approach for hedge accounting treatment, and under a prospective approach for the amended disclosure requirements. Adoption of this ASU did not have a material impact on the firm’s financial condition, results of operations or cash flows. See Note 7 for further information. Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (ASC 220). In February 2018, the FASB issued ASU No. 2018-02, 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 financial condition, results of operations or cash flows. Changes to the Disclosure Requirements for Fair Value Measurement (ASC 820). In August 2018, the FASB issued ASU No. 2018-13,

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 8 for information about other financial assets and financial liabilities at fair value. The table below presents financial instruments owned and financial instruments sold, but not yet purchased. $ in millions Financial Instruments Owned Financial Instruments Sold, But Not Yet Purchased As of December 2018 Money market instruments $ 2,635 $ – Government and agency obligations: U.S. 110,616 5,080 Non-U.S. 43,607 25,347 Loans and securities backed by: Commercial real estate 3,369 – Residential real estate 12,949 1 Corporate debt instruments 31,207 10,411 State and municipal obligations 1,233 – Other debt obligations 1,864 1 Equity securities 76,170 25,463 Commodities 3,729 – Investments in funds at NAV 3,936 – Subtotal 291,315 66,303 Derivatives 44,846 42,594 Total $336,161 $108,897 As of December 2017 Money market instruments $ 1,608 $ Government and agency obligations: U.S. 76,418 17,911 Non-U.S. 33,956 23,311 Loans and securities backed by: Commercial real estate 3,436 1 Residential real estate 11,993 – Corporate debt instruments 33,683 7,153 State and municipal obligations 1,471 – Other debt obligations 2,164 1 Equity securities 96,132 23,882 Commodities 3,194 40 Investments in funds at NAV 4,596 – Subtotal 268,651 72,299 Derivatives 47,337 39,631 Total $315,988 $111,930 In the table above: • Money market instruments includes commercial paper, certificates of deposit and time deposits, substantially all of which have a maturity of less than one year. • Corporate debt instruments includes corporate loans and debt securities. • Equity securities includes public and private equities, exchange-traded funds and convertible debentures. Such amounts include investments accounted for at fair value under the fair value option where the firm would otherwise apply the equity method of accounting of $7.91 billion as of December 2018 and $8.49 billion as of December 2017. Gains and Losses from Market Making and Other Principal Transactions The table below presents market making revenues by major product type and other principal transactions revenues.

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. Inputs are unadjusted quoted prices in active markets to which the firm had access at the measurement date for identical, unrestricted assets or liabilities. Level 2. Inputs to valuation techniques are observable, either directly or indirectly. Level 3. One or more inputs to valuation techniques are significant and unobservable. 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 December $ in millions 2018 2017 Total level 1 financial assets $170,463 $155,086 Total level 2 financial assets 354,515 395,606 Total level 3 financial assets 22,181 19,201 Investments in funds at NAV 3,936 4,596 Counterparty and cash collateral netting (49,383 ) (56,366 ) Total financial assets at fair value $501,712 $518,123 Total assets $931,796 $916,776 Total level 3 financial assets divided by: Total assets 2.4% 2.1% Total financial assets at fair value 4.4% 3.7% Total level 1 financial liabilities $ 54,151 $ 63,589 Total level 2 financial liabilities 258,335 261,719 Total level 3 financial liabilities 23,804 19,620 Counterparty and cash collateral netting (39,786 ) (39,866 ) Total financial liabilities at fair value $296,504 $305,062 Total level 3 financial liabilities divided by 8.0% 6.4% 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.

Text Block [Abstract]
Cash Instruments	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. Loans and securities backed by commercial real estate are directly or indirectly collateralized by a single commercial real estate property or a portfolio of properties, and may include tranches of varying levels of subordination. Significant inputs are generally determined based on relative value analyses and include: • 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. Loans and securities backed by residential real estate are directly or indirectly collateralized by portfolios of residential real estate and may include tranches of varying levels of subordination. Significant inputs are generally determined based on relative value analyses, which incorporate comparisons to instruments with similar collateral and risk profiles. Significant inputs include: • 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. Corporate debt instruments includes corporate loans and debt securities. Significant inputs for corporate debt instruments are generally determined based on relative value analyses, which incorporate comparisons both to prices of credit default swaps that reference the same or similar underlying instrument or entity and to other debt instruments for the same issuer for which observable prices or broker quotations are available. Significant inputs include: • 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. Equity securities includes private equity securities and convertible debentures. Recent third-party completed or pending transactions (e.g., merger proposals, tender offers, debt restructurings) are considered to be the best evidence for any change in fair value. When these are not available, the following valuation methodologies are used, as appropriate: • 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 includes U.S. government and agency obligations, 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.

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 $ in millions 2018 2017 Loans and securities backed by commercial real estate Level 3 assets $1,019 $1,126 Yield 6.9% to 22.5% (12.4% ) 4.6% to 22.0% (13.4% ) Recovery rate 9.7% to 78.4% (42.9% ) 14.3% to 89.0% (43.8% ) Duration (years) 0.4 to 7.1 (3.7 ) 0.8 to 6.4 (2.1 ) Loans and securities backed by residential real estate Level 3 assets $663 $668 Yield 2.6% to 19.3% (9.2% ) 2.3% to 15.0% (8.3% ) Cumulative loss rate 8.3% to 37.7% (19.2% ) 12.5% to 43.0% (21.8% ) Duration (years) 1.4 to 14.0 (6.7 ) 0.7 to 14.0 (6.9 ) Corporate debt instruments Level 3 assets $4,224 $3,270 Yield 0.7% to 32.3% (11.9% ) 3.6% to 24.5% (12.3% ) Recovery rate 0.0% to 78.0% (57.8% ) 0.0% to 85.3% (62.8% ) Duration (years) 0.4 to 13.5 (3.4 ) 0.5 to 7.6 (3.2 ) Equity securities Level 3 assets $10,725 $9,904 Multiples 1.0x to 23.6x (8.1x ) 1.1x to 30.5x (8.9x ) Discount rate/yield 6.5% to 22.1% (14.3% ) 3.0% to 20.3% (14.0% ) Capitalization rate 3.5% to 12.3% (6.1% ) 4.3% to 12.0% (6.1% ) Other cash instruments Level 3 assets $596 $427 Yield 4.1% to 11.5% (9.2% ) 4.0% to 11.7% (8.4% ) Duration (years) 2.2 to 4.8 (2.8 ) 3.5 to 11.4 (5.1 ) 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 December 2018 and December 2017. 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. 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.

The net realized and unrealized gains on level 3 cash instrument assets of $1.32 billion (reflecting $501 million of net realized gains and $816 million of net unrealized gains) for 2018 included gains/(losses) of $(96) million reported in market making, $908 million reported in other principal transactions and $505 million reported in interest income. The net unrealized gains on level 3 cash instrument assets for 2018 primarily reflected gains on private equity securities, principally driven by strong corporate performance and company-specific events. Transfers into level 3 during 2018 primarily reflected transfers of certain private equity securities and corporate debt instruments from level 2, principally due to reduced price transparency as a result of a lack of market evidence, including fewer market transactions in these instruments. Transfers out of level 3 during 2018 primarily reflected transfers of certain private equity securities and corporate debt instruments to level 2, principally due to increased price transparency as a result of market evidence, including market transactions in these instruments, and transfers of certain other corporate debt instruments to level 2, principally due to certain unobservable yield and duration inputs no longer being significant to the valuation of these instruments. Year Ended December 2017. The net realized and unrealized gains on level 3 cash instrument assets of $1.56 billion (reflecting $419 million of net realized gains and $1.14 billion of net unrealized gains) for 2017 included gains/(losses) of $(99) million reported in market making, $1.13 billion reported in other principal transactions and $532 million reported in interest income. The net unrealized gains on level 3 cash instrument assets for 2017 primarily reflected gains on private equity securities, principally driven by strong corporate performance and company-specific events. Transfers into level 3 during 2017 primarily reflected transfers of certain corporate debt instruments and private equity securities from level 2, principally due to reduced price transparency as a result of a lack of market evidence, including fewer market transactions in these instruments. Transfers out of level 3 during 2017 primarily reflected transfers of certain corporate debt instruments and private equity securities to level 2, principally due to increased price transparency as a result of market evidence, including market transactions in these instruments, and transfers of certain corporate debt instruments to level 2, principally due to certain unobservable yield and duration inputs no longer being significant to the valuation of these instruments.

Such losses were not material as of December 2017. • 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. This extension is applicable to substantially all of the firm’s remaining investments in, and relationships with, such covered funds.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
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. As a market maker, the firm enters into derivative transactions to provide liquidity to clients and to facilitate the transfer and hedging of their risks. In this role, the firm typically acts as principal and is required to commit capital to provide execution, and maintains inventory in response to, or in anticipation of, client demand. Risk Management. The firm also enters into derivatives to actively manage risk exposures that arise from its market-making and investing and lending activities in derivative and cash instruments. The firm’s holdings and exposures are hedged, in many cases, on either a portfolio or risk-specific basis, as opposed to an 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.

As of December 2017, the impact of this change would have been a reduction in gross interest rate derivative assets of $3.6 billion and gross interest rate derivative liabilities of $1.9 billion, and a corresponding decrease in counterparty and cash collateral netting, with no impact to the consolidated statements of financial condition. • On November 19, 2018, a clearing organization revised its rules to calculate notional amounts for certain exchange-traded derivative contracts. The impact of this rule change, as of the effective date, was a decrease in the notional amounts of derivative contracts of approximately $7 trillion, substantially all of which related to interest rate derivatives, with no change to their fair value. 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 December 2018 Assets Interest rates $ 12 $ 235,680 $ 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 ) As of December 2017 Assets Interest rates $ $ $ $ Credit – 19,053 3,640 22,693 Currencies – 95,401 140 95,541 Commodities – 13,727 353 14,080 Equities 8 50,870 409 51,287 Gross fair value 26 461,984 4,853 466,863 Counterparty netting in levels – (362,109 ) (1,051 ) (363,160 ) Subtotal $ $ $ $ Cross-level counterparty netting (894 ) Cash collateral netting (55,472 ) Net fair value $ Liabilities Interest rates $ ) $ ) $ ) $ ) Credit – (19,135 ) (2,135 ) (21,270 ) Currencies – (96,160 ) (321 ) (96,481 ) Commodities – (15,842 ) (306 ) (16,148 ) Equities (28 ) (53,902 ) (1,658 ) (55,588 ) Gross fair value (56 ) (437,460 ) (5,141 ) (442,657 ) Counterparty netting in levels – 362,109 1,051 363,160 Subtotal $ ) $ ) $ ) $ ) Cross-level counterparty netting 894 Cash collateral netting 38,972 Net fair value $ ) 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 2018 2017 Interest rates, net $(109) $(410) Correlation (10)% to 86% (66%/64%) (10)% to 95% (71%/79%) Volatility (bps) 31 to 150 (74/65) 31 to 150 (84/78) Credit, net $1,672 $1,505 Correlation N/A 28% to 84% (61%/60%) Credit spreads (bps) 1 to 810 (109/63) 1 to 633 (69/42) Upfront credit points 2 to 99 (44/40) 0 to 97 (42/38) Recovery rates 25% to 70% (40%/40%) 22% to 73% (68%/73%) Currencies, net $461 $(181) Correlation 10% to 70% (40%/36%) 49% to 72% (61%/62%) Commodities, net $112 $47 Volatility 10% to 75% (28%/27%) 9% to 79% (24%/24%) Natural gas spread $(2.32) to $4.68 ($(0.26)/$(0.30)) $(2.38) to $3.34 Oil spread $(3.44) to $16.62 ($4.53/$3.94) $(2.86) to $23.61 Equities, net $(1,546) $(1,249) Correlation (68)% to 97% (48%/51%) (36)% to 94% (50%/52%) Volatility 3% to 102% (20%/18%) 4% to 72% (24%/22%) 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 was not significant to the valuation of level 3 credit derivatives as of December 2018. • 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 December 2018 and December 2017, 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. Year Ended December $ in millions 2018 2017 Total level 3 derivatives Beginning balance $ (288 ) $(1,217 ) Net realized gains/(losses) (113 ) (119 ) Net unrealized gains/(losses) 1,251 (436 ) Purchases 612 301 Sales (1,510 ) (611 ) Settlements 573 1,891 Transfers into level 3 34 (39 ) Transfers out of level 3 31 (58 ) Ending balance $ 590 $ (288 ) In the table above: • Changes in fair value are presented for all derivative assets and liabilities that are classified in level 3 as of the end of the period. • Net unrealized gains/(losses) relates to instruments that were still held at period-end. • Transfers between levels of the fair value hierarchy are reported at the beginning of the reporting period in which they occur. 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. The table below disaggregates, by major product type, the information for level 3 derivatives included in the summary table above.

The net realized and unrealized gains on level 3 derivatives of $1.14 billion (reflecting $113 million of net realized losses and $1.25 billion of net unrealized gains) for 2018 included gains of $1.11 billion reported in market making and $28 million reported in other principal transactions. The net unrealized gains on level 3 derivatives for 2018 were primarily attributable to gains on certain equity derivatives, reflecting the impact of a decrease in certain equity prices and gains on certain currency derivatives, primarily reflecting the impact of changes in foreign exchange rates. Both transfers into level 3 derivatives and transfers out of level 3 derivatives during 2018 were not material. Year Ended December 2017. The net realized and unrealized losses on level 3 derivatives of $555 million (reflecting $119 million of net realized losses and $436 million of net unrealized losses) for 2017 included losses of $90 million reported in market making and $465 million reported in other principal transactions. The net unrealized losses on level 3 derivatives for 2017 were primarily attributable to losses on certain equity derivatives, reflecting the impact of changes in equity prices, losses on certain currency derivatives, primarily reflecting the impact of changes in foreign exchanges rates, and losses on certain credit derivatives, reflecting the impact of tighter credit spreads, partially offset by gains on certain commodity derivatives, reflecting the impact of an increase in commodity prices. Transfers into level 3 derivatives during 2017 were not material. Transfers out of level 3 derivatives during 2017 primarily reflected transfers of certain credit derivatives assets to level 2, principally due to certain unobservable inputs no longer being significant to the valuation of these derivatives.

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 December 2018, written credit derivatives had a total gross notional amount of $554.17 billion and purchased credit derivatives had a total gross notional amount of $603.00 billion, for total net notional purchased protection of $48.83 billion. As of December 2017, written credit derivatives had a total gross notional amount of $611.04 billion and purchased credit derivatives had a total gross notional amount of $643.37 billion, for total net notional purchased protection of $32.33 billion. Substantially all of the firm’s written and purchased credit derivatives are credit default swaps. 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 On an ongoing basis, 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 $371 million for 2018, $66 million for 2017 and $85 million for 2016. 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 December $ in millions 2018 2017 Fair value of assets $ 980 $ 882 Fair value of liabilities 1,297 1,200 Net liability $ 317 $ 318 Notional amount $10,229 $9,578 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 borrowings and unsecured long-term borrowings with the related borrowings. See Note 8 for further information. 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.

Fair Value Disclosures [Abstract]
Fair Value Option	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 Client Execution (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 used to value other financial assets and financial liabilities at fair value, including the ranges of significant unobservable inputs used to value the level 3 instruments within these categories. These ranges represent the significant unobservable inputs that were used in the valuation of each type of other financial assets and financial liabilities at fair value. 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 instrument. For example, the highest yield presented below for other secured financings is appropriate for valuing a specific agreement in that category but may not be appropriate for valuing any other agreements in that category. Accordingly, the ranges of inputs presented below do not represent uncertainty in, or possible ranges of, fair value measurements of the firm’s level 3 other financial assets and financial liabilities. Resale and Repurchase Agreements and Securities Borrowed and Loaned. The significant inputs to the valuation of resale and repurchase agreements and securities borrowed and loaned are funding spreads, the amount and timing of expected future cash flows and interest rates. As of both December 2018 and December 2017, the firm had no level 3 resale agreements, securities borrowed or securities loaned. As of both December 2018 and December 2017, the firm’s level 3 repurchase agreements were not material. See Note 10 for further information about collateralized agreements and financings. Other Secured Financings. The significant inputs to the valuation of other secured financings at fair value are the amount and timing of expected future cash flows, interest rates, funding spreads, the fair value of the collateral delivered by the firm (which is determined using the amount and timing of expected future cash flows, market prices, market yields and recovery assumptions) and the frequency of additional collateral calls. As of December 2018, the firm’s level 3 other secured financings were not material. The ranges of significant unobservable inputs used to value level 3 other secured financings as of December 2017 are as follows: • Yield: 0.6% to 13.0% (weighted average: 3.3%) • Duration: 0.7 to 11.0 years (weighted average: 2.7 years) Generally, increases in yield or duration, in isolation, would have resulted in a lower fair value measurement as of December 2017. Due to the distinctive nature of each of the firm’s level 3 other secured financings, the interrelationship of inputs is not necessarily uniform across such financings. See Note 10 for further information about collateralized agreements and financings. Unsecured Short-term and Long-term Borrowings. The significant inputs to the valuation of unsecured short-term and long-term borrowings at fair value are the amount and timing of expected future cash flows, interest rates, the credit spreads of the firm, as well as commodity prices in the case of prepaid commodity transactions. The inputs used to value the embedded derivative component of hybrid financial instruments are consistent with the inputs used to value the firm’s other derivative instruments. See Note 7 for further information about derivatives, Note 15 for further information about unsecured short-term borrowings, and Note 16 for further information about 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. Customer and other receivables at fair value primarily consist of prepaid commodity transactions and transfers of assets accounted for as secured loans rather than purchases. The significant inputs to the valuation of such receivables are commodity prices, interest rates, the amount and timing of expected future cash flows and funding spreads. As of both December 2018 and December 2017, the firm’s level 3 customer and other receivables were not material. Deposits. The significant inputs to the valuation of time deposits are interest rates and the amount and timing of future cash flows. The inputs used to value the embedded derivative component of hybrid financial instruments are consistent with the inputs used to value the firm’s other derivative instruments. See Note 7 for further information about derivatives and Note 14 for further information about deposits. The firm’s deposits that are classified in level 3 are hybrid financial instruments. As the significant unobservable inputs used to value hybrid financial 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. Level 3 Rollforward The table below presents a summary of the changes in fair value for level 3 other financial assets and financial liabilities accounted for at fair value.

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. The table below disaggregates, by the consolidated statements of financial condition line items, the information for other financial liabilities included in the summary table above.

The net realized and unrealized gains on level 3 other financial liabilities of $1.52 billion (reflecting $491 million of net realized losses and $2.01 billion of net unrealized gains) for 2018 included gains/(losses) of $883 million reported in market making, $(1) million reported in other principal transactions and $(1) million reported in interest expense in the consolidated statements of earnings, and gains of $641 million reported in debt valuation adjustment in the consolidated statements of comprehensive income. The net unrealized gains on level 3 other financial liabilities for 2018 primarily reflected gains on certain hybrid financial instruments included in unsecured long-term borrowings, principally due to the impact of wider credit spreads and increases in interest rates, and gains on certain hybrid financial instruments included in unsecured short-term borrowings, principally due to a decrease in global equity prices. Transfers into level 3 other financial liabilities during 2018 primarily reflected transfers of certain hybrid financial instruments included in unsecured long-term borrowings from level 2, principally due to reduced transparency of certain inputs used to value these instruments as a result of a lack of market transactions in similar instruments. Transfers out of level 3 other financial liabilities during 2018 primarily reflected transfers of certain hybrid financial instruments included in unsecured long-term and short-term borrowings to level 2, principally due to increased transparency of certain volatility and correlation inputs used to value these instruments. Year Ended December 2017. The net realized and unrealized losses on level 3 other financial liabilities of $1.41 billion (reflecting $362 million of net realized losses and $1.05 billion of net unrealized losses) for 2017 included losses of $1.20 billion reported in market making, $45 million reported in other principal transactions and $10 million reported in interest expense in the consolidated statements of earnings, and losses of $149 million reported in debt valuation adjustment in the consolidated statements of comprehensive income. The net unrealized losses on level 3 other financial liabilities for 2017 primarily reflected losses on certain hybrid financial instruments included in unsecured long-term and short-term borrowings, principally due to an increase in global equity prices and the impact of tighter credit spreads, and losses on certain hybrid financial instruments included in deposits, principally due to the impact of an increase in the market value of the underlying assets. Transfers into level 3 other financial liabilities during 2017 primarily reflected transfers of certain hybrid financial instruments included in unsecured long-term borrowings from level 2, principally due to reduced transparency of volatility inputs used to value these instruments. Transfers out of level 3 other financial liabilities during 2017 primarily reflected transfers of certain hybrid financial instruments included in unsecured long-term and short-term borrowings to level 2, principally due to increased transparency of certain inputs used to value these instruments as a result of market transactions in similar instruments, and transfers of certain hybrid financial instruments included in deposits to level 2, principally due to increased transparency of correlation and volatility inputs used to value these instruments. 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. Year Ended December $ in millions 2018 2017 2016 Unsecured short-term borrowings $1,443 $(2,585 ) $(1,028 ) Unsecured long-term borrowings 926 (1,357 ) 584 Other liabilities (68 ) 222 (55 ) Other 349 (620 ) (630 ) Total $2,650 $(4,340 ) $(1,129 ) 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 2018, 2017 and 2016. 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 December $ in millions 2018 2017 Performing loans and long-term receivables Aggregate contractual principal in excess of fair value $1,837 $ 952 Loans on nonaccrual status and/or more than 90 days past due Aggregate contractual principal in excess of fair value $5,260 $5,266 Aggregate fair value of loans on nonaccrual status and/or more than 90 days past due $2,010 $2,104 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 $45 million as of December 2018 and $31 million as of December 2017, and the related total contractual amount of these lending commitments was $7.72 billion as of December 2018 and $9.94 billion as of December 2017. See Note 18 for further information about lending commitments. 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 December 2018 and December 2017. The aggregate contractual principal amount of unsecured long-term borrowings for which the fair value option was elected exceeded the related fair value by $2.38 billion as of December 2018 and $1.69 billion as of December 2017. The amounts above include both principal- 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 $211 million for 2018, $268 million for 2017 and $281 million for 2016. The firm generally calculates the fair value of loans and lending commitments for which the fair value option is elected by discounting future cash flows at a rate which incorporates the instrument-specific credit spreads. For floating-rate loans and lending commitments, substantially all changes in fair value are attributable to changes in instrument-specific credit spreads, whereas for fixed-rate loans and lending commitments, changes in fair value are also attributable to changes in interest rates. 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 DVA gains/(losses) on financial liabilities for which the fair value option was elected. Year Ended December $ in millions 2018 2017 2016 DVA (pre-tax) $3,389 $(1,232 ) $(844 ) DVA (net of tax) $2,553 $ (807 ) $(544 ) 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 loss upon extinguishment of such financial liabilities were not material for 2018, 2017 and 2016.

Receivables [Abstract]
Loans Receivable	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 December $ in millions 2018 2017 Corporate loans $37,283 $30,749 PWM loans 17,219 16,591 Commercial real estate loans 11,441 7,987 Residential real estate loans 7,284 6,234 Consumer loans 4,536 1,912 Other loans 3,893 3,263 Total loans receivable, gross 81,656 66,736 Allowance for loan losses (1,066 ) (803 ) Total loans receivable $80,590 $65,933 The fair value of loans receivable was $80.74 billion as of December 2018 and $66.29 billion as of December 2017. Had these loans been carried at fair value and included in the fair value hierarchy, $40.64 billion as of December 2018 and $38.75 billion as of December 2017 would have been classified in level 2, and $40.10 billion as of December 2018 and $27.54 billion as of December 2017 would have been classified in level 3. 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 December $ in millions 2018 2017 Corporate $113,484 $118,553 Other 7,513 5,951 Total $120,997 $124,504 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 $443 million (including allowance for losses of $286 million) as of December 2018 and $423 million (including allowance for losses of $274 million) as of December 2017. • The estimated fair value of such lending commitments were liabilities of $3.78 billion as of December 2018 and $2.27 billion as of December 2017. Had these lending commitments been carried at fair value and included in the fair value hierarchy, $1.12 billion as of December 2018 and $772 million as of December 2017 would have been classified in level 2, and $2.66 billion as of December 2018 and $1.50 billion as of December 2017 would have been classified in level 3. 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 December $ in millions 2018 2017 Commercial real estate loans $ 581 $1,116 Residential real estate loans 2,457 3,327 Other loans 4 10 Total gross carrying value $3,042 $4,453 Total outstanding principal balance $5,576 $9,512 Total accretable yield $ 459 $ 662 Year Ended December $ in millions 2018 2017 2016 Acquired during the period Fair value $ 839 $1,769 $2,514 Expected cash flows $ 937 $1,961 $2,818 Contractually required cash flows $1,881 $4,092 $6,389 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’s risk assessment process includes evaluating the credit quality of its loans receivable. For loans receivable (excluding PCI and consumer loans) and lending commitments, the firm performs credit reviews which include initial and ongoing analyses of its borrowers. A credit review is an independent analysis of the capacity and willingness of a borrower to meet its financial obligations, resulting in an internal credit rating. The determination of internal credit ratings also incorporates assumptions with respect to the nature of and outlook for the borrower’s industry and the economic environment. The firm also assigns a regulatory risk rating to such loans based on the definitions provided by the U.S. federal bank regulatory agencies. 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 the firm’s 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 $7.58 billion as of December 2018 and $6.37 billion as of December 2017) and lending commitments by an internally determined public rating agency equivalent and by regulatory risk rating. $ in millions Loans Lending Total Credit Rating Equivalent 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 As of December 2017 Investment-grade $24,192 $ 89,409 $113,601 Non-investment-grade 36,179 35,095 71,274 Total $60,371 $124,504 $184,875 Regulatory Risk Rating 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 As of December 2017 Non-criticized/pass $56,720 $119,427 $176,147 Criticized 3,651 5,077 8,728 Total $60,371 $124,504 $184,875 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 December $ in millions 2018 2017 Consumer loans, gross $4,536 $1,912 Refreshed FICO credit score Greater than or equal to 660 88% 89% Less than 660 12% 11% 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. Loans receivable (excluding PCI loans) are determined to be impaired when it is probable that the firm will not collect all principal and interest due under the contractual terms. At that time, loans are generally placed on nonaccrual status and all accrued but uncollected interest is reversed against interest income and interest subsequently collected is recognized on a cash basis to the extent the loan balance is deemed collectible. Otherwise, all cash received is used to reduce the outstanding loan balance. A loan is considered past due when a principal or interest payment has not been made according to its contractual terms. 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 $838 million as of December 2018 and $845 million as of December 2017. Such loans included $27 million as of December 2018 and $61 million as of December 2017 of corporate loans that were modified in a troubled debt restructuring. The firm did not have any lending commitments related to these loans as of both December 2018 and December 2017. The amount of loans 30 days or more past due was $208 million as of December 2018 and $567 million as of December 2017. 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.

Text Block [Abstract]
Collateralized Agreements and Financings	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 December $ in millions 2018 2017 Resale agreements $139,258 $120,822 Securities borrowed $135,285 $190,848 Repurchase agreements $ 78,723 $ 84,718 Securities loaned $ 11,808 $ 14,793 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 $23.14 billion as of December 2018 and $78.19 billion as of December 2017, and securities loaned of $3.24 billion as of December 2018 and $5.36 billion as of December 2017 were at fair value. 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 5 through 8. Had these agreements been included in the firm’s fair value hierarchy, they would have been classified in level 2 as of both December 2018 and December 2017. Offsetting Arrangements The table below presents the gross and net resale and repurchase agreements and securities borrowed and loaned transactions, and the related amount of counterparty netting included in the consolidated statements of financial condition, as well as the amounts of counterparty netting and cash and securities collateral 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 $8.47 billion as of December 2018 and $5.31 billion as of December 2017. 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 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 December 2018 and December 2017. The table below presents information about other secured financings. $ in millions U.S. Non-U.S. Total 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 As of December 2017 Other secured financings (short-term): At fair value $ 7,704 $ 6,856 $14,560 At amortized cost – 336 336 Other secured financings (long-term): At fair value 6,779 3,006 9,785 At amortized cost 107 – 107 Total other secured financings $14,590 $10,198 $24,788 Other secured financings collateralized by: Financial instruments $12,454 $ 9,870 $22,324 Other assets $ 2,136 $ 328 $ 2,464 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 long-term other secured financings at amortized cost had a weighted average interest rate of 4.02% as of December 2018 and 3.89% as of December 2017.

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.

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 primarily are accounted for at fair value and classified in level 2 of the fair value hierarchy. Beneficial interests and other 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.

In addition to the interests in the table above, the firm had other continuing involvement in the form of derivative transactions and commitments with certain nonconsolidated VIEs. The carrying value of these derivatives and commitments was a net asset of $75 million as of December 2018 and $86 million as of December 2017, and the notional amount of these derivatives and commitments was $1.09 billion as of December 2018 and $1.26 billion as of December 2017. The notional amounts of these derivatives and commitments are included in maximum exposure to loss in the nonconsolidated VIE table in Note 12. The table below presents information about the weighted average key economic assumptions used in measuring the fair value of mortgage-backed retained interests. As of December $ in millions 2018 2017 Fair value of retained interests $ 3,151 $2,071 Weighted average life (years) 7.2 6.0 Constant prepayment rate 11.9% 9.4% Impact of 10% adverse change $ (27 ) $ (19 ) Impact of 20% adverse change $ (53 ) $ (35 ) Discount rate 4.7% 4.2% Impact of 10% adverse change $ (75 ) $ (35 ) Impact of 20% adverse change $ (147 ) $ (70 ) In the table above: • Amounts do not reflect the benefit of other financial instruments that are held to mitigate risks inherent in these retained interests. • Changes in fair value based on an adverse variation in assumptions generally cannot be extrapolated because the relationship of the change in assumptions to the change in fair value is not usually linear. • The impact of a change in a particular assumption is calculated independently of changes in any other assumption. 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 $133 million and a weighted average life of 4.2 years as of December 2018, and a fair value of $56 million and a weighted average life of 4.5 years as of December 2017. 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 December 2018 and December 2017. The firm’s maximum exposure to adverse changes in the value of these interests is the carrying value of $133 million as of December 2018 and $56 million as of December 2017.

Variable Interest Entities

Variable Interest Entities	12 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	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. The firm sells residential and commercial mortgage loans and securities to mortgage-backed VIEs and may retain beneficial interests in the assets sold to these VIEs. The firm purchases and sells beneficial interests issued by mortgage-backed VIEs in connection with market-making activities. In addition, the firm may enter into derivatives with certain of these VIEs, primarily interest rate swaps, which are typically not variable interests. The firm generally enters into derivatives with other counterparties to mitigate its risk. Real Estate, Credit- and Power-Related and Other Investing VIEs. The firm purchases equity and debt securities issued by and makes loans to VIEs that hold real estate, performing and nonperforming debt, distressed loans, power-related assets and equity securities. The firm generally does not sell assets to, or enter into derivatives with, these VIEs. Corporate Debt and Other Asset-Backed VIEs. The firm structures VIEs that issue notes to clients, purchases and sells beneficial interests issued by corporate debt and other asset-backed VIEs in connection with market-making activities, and makes loans to VIEs that warehouse corporate debt. Certain of these VIEs synthetically create the exposure for the beneficial interests they issue by entering into credit derivatives with the firm, rather than purchasing the underlying assets. In addition, the firm may enter into derivatives, such as total return swaps, with certain corporate debt and other asset-backed VIEs, under which the firm pays the VIE a return due to the beneficial interest holders and receives the return on the collateral owned by the VIE. The collateral owned by these VIEs is primarily other asset-backed loans and securities. The firm generally can be removed as the total return swap counterparty and enters into derivatives with other counterparties to mitigate its risk related to these swaps. The firm may sell assets to the corporate debt and other asset-backed VIEs it structures. Principal-Protected Note VIEs. The firm structures VIEs that issue principal-protected notes to clients. These VIEs own portfolios of assets, principally with exposure to hedge funds. Substantially all of the principal protection on the notes issued by these VIEs is provided by the asset portfolio rebalancing that is required under the terms of the notes. The firm enters into total return swaps with these VIEs under which the firm pays the VIE the return due to the principal-protected note holders and receives the return on the assets owned by the VIE. The firm may enter into derivatives with other counterparties to mitigate its risk. The firm also obtains funding through these VIEs. Investments in Funds. The firm makes equity investments in certain investment fund VIEs it manages and is entitled to receive fees from these VIEs.

During the third quarter of 2018, the firm entered into a sale and leaseback agreement, which closed in January 2019, to sell this property for $1.53 billion. The assets were classified as held for sale during the fourth quarter of 2018 when the construction of the property was substantially completed. Substantially all of the sale proceeds in excess of the carrying value of the property will be recognized over the life of the lease as a reduction to occupancy expense. In accordance with ASU No. 2016-02, right-of-use No. 2016-02. • Miscellaneous receivables and other included other assets classified as held for sale of $365 million as of December 2018 and $634 million as of December 2017 related to the firm’s consolidated investments within its Investing & Lending segment, substantially all of which consisted of property and equipment. • Miscellaneous receivables and other included equity-method investments of $357 million as of December 2018 and $275 million as of December 2017. Goodwill and Identifiable Intangible Assets Goodwill. The table below presents the carrying value of goodwill. As of December $ in millions 2018 2017 Investment Banking: Financial Advisory $ 98 $ 98 Underwriting 183 183 Institutional Client Services: FICC Client Execution 269 269 Equities client execution 2,403 2,403 Securities services 105 105 Investing & Lending 91 2 Investment Management 609 605 Total $3,758 $3,665 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. The firm considered the following factors in the qualitative assessment performed in the fourth quarter when evaluating whether it was more likely than not that the fair value of a reporting unit was less than its carrying value: • Performance Indicators. pre-tax • Firm and Industry Events. • Macroeconomic Indicators. • Fair Value Indicators. price-to-book price-to-earnings 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. Subsequent to the qualitative assessment, the firm’s stock price declined towards the end of the year. Due to the short period of time of this decline and continued favorable outlook for the firm’s performance, the firm determined that this was not a triggering event for further assessment. Identifiable Intangible Assets. The table below presents identifiable intangible assets by segment and type.

The firm acquired $113 million of intangible assets during 2017, primarily related to acquired leases, with a weighted average amortization period of five years. Substantially all of the firm’s identifiable intangible assets are considered to have finite useful lives and are amortized over their estimated useful lives generally using the straight-line method.

To the extent the carrying value of an asset 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 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 if the carrying value of the asset exceeds its estimated fair value. During 2018, 2017 and 2016, impairments were not material to the firm’s results of operations or financial condition.

As of December 2017, the outstanding par amount of junior subordinated debt held by the Trust was $1.17 billion and the outstanding par amount of Trust Preferred Securities and common beneficial interests issued by the Trust was $1.13 billion and $35.1 million, respectively. The Trust is a wholly-owned finance subsidiary of the firm for regulatory and legal purposes but is not consolidated for accounting purposes. The firm pays interest semi-annually on the junior subordinated debt at an annual rate of 6.345% and the debt matures on February 15, 2034. The coupon rate and the payment dates applicable to the beneficial interests are the same as the interest rate and payment dates for the junior subordinated debt. The firm has the right, from time to time, to defer payment of interest on the junior subordinated debt, and therefore cause payment on the Trust’s preferred beneficial interests to be deferred, in each case up to ten consecutive semi-annual periods. During any such deferral period, the firm will not be permitted to, among other things, pay dividends on or make certain repurchases of its common stock. The Trust is not permitted to pay any distributions on the common beneficial interests held by Group Inc. unless all dividends payable on the preferred beneficial interests have been paid in full. The firm has covenanted in favor of the holders of Group Inc.’s 6.345% junior subordinated debt due February 15, 2034, that, subject to certain exceptions, the firm will not redeem or purchase the capital securities issued by Goldman Sachs Capital II and Goldman Sachs Capital III (APEX Trusts) or shares of Group Inc.’s Perpetual Non-Cumulative Non-Cumulative Non-Cumulative The APEX Trusts hold Group Inc.’s Series E Preferred Stock and Series F Preferred Stock. These trusts are Delaware statutory trusts sponsored by the firm and wholly-owned finance subsidiaries of the firm for regulatory and legal purposes but are not consolidated for accounting purposes.

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. As of December $ in millions 2018 2017 Held for investment $120,997 $124,504 Held for sale 8,602 9,838 At fair value 7,983 9,404 Total $137,582 $143,746 In the table above: • 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 relates to the firm’s Investing & Lending segment. Commercial Lending. The firm’s commercial lending commitments were primarily extended to investment-grade corporate borrowers. Such commitments included $93.99 billion as of December 2018 and $85.98 billion as of December 2017, related to relationship lending activities (principally used for operating and general corporate purposes) and $27.92 billion as of December 2018 and $42.41 billion as of December 2017, related to other investment banking activities (generally extended for contingent acquisition financing and are often intended to be short-term in nature, as borrowers often seek to replace them with other funding sources). The firm also extends lending commitments in connection with other types of corporate lending, as well as commercial real estate financing. See Note 9 for further information about funded loans. 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 $15.52 billion as of December 2018 and $25.70 billion as of December 2017. 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 $1.0 billion, of which $550 million of protection had been provided as of both December 2018 and December 2017. 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. The firm provides financing to clients who warehouse financial assets. These arrangements are secured by the warehoused assets, primarily consisting of consumer and corporate loans. Contingent and Forward Starting Collateralized Agreements / Forward Starting Collateralized Financings Forward starting collateralized agreements includes resale and securities borrowing agreements, and forward starting collateralized financings includes repurchase and secured lending agreements that settle at a future date, generally within three business days. The firm also enters into commitments to provide contingent financing to its clients and counterparties through resale agreements. The firm’s funding of these commitments depends on the satisfaction of all contractual conditions to the resale agreement and these commitments can expire unused. Letters of Credit The firm has commitments under letters of credit issued by various banks which the firm provides to counterparties in lieu of securities or cash to satisfy various collateral and margin deposit requirements. Investment Commitments Investment commitments includes commitments to invest in private equity, real estate and other assets directly and through funds that the firm raises and manages. Investment commitments included $2.42 billion as of December 2018 and $2.09 billion as of December 2017, related to commitments to invest in funds managed by the firm. If these commitments are called, they would be funded at market value on the date of investment. Leases The firm has contractual obligations under long-term noncancelable lease agreements for office space expiring on various dates through 2069. Certain agreements are subject to periodic escalation provisions for increases in real estate taxes and other charges. The table below presents future minimum rental payments, net of minimum sublease rentals. $ in millions As of 2019 $ 281 2020 271 2021 218 2022 177 2023 142 2024 - thereafter 1,310 Total $2,399 Rent charged to operating expense was $292 million for 2018, $273 million for 2017 and $244 million for 2016. The amounts in the table above do not include lease payments arising from the sale and leaseback of the firm’s new European headquarters as this agreement closed in January 2019. See Note 13 for further information about the sale and leaseback agreement. Operating leases include office space held in excess of current requirements. Rent expense relating to space held for growth is included in occupancy expenses. The firm records a liability, based on the fair value of the remaining lease rentals reduced by any potential or existing sublease rentals, for leases where the firm has ceased using the space and management has concluded that the firm will not derive any future economic benefits. Costs to terminate a lease before the end of its term are recognized and measured at fair value on termination. Total occupancy expenses for space held in excess of the firm’s current requirements and exit costs related to its office space were not material for both 2018 and 2017, and were approximately $68 million for 2016. Contingencies Legal Proceedings. See Note 27 for information about legal proceedings, including certain mortgage-related matters, and agreements the firm has entered into to toll the statute of limitations. Certain Mortgage-Related Contingencies. During the period 2005 through 2008 in connection with both sales and securitizations of loans, the firm provided loan-level representations and/or assigned the loan-level representations from the party from whom the firm purchased the loans. 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. Based upon 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. Other Contingencies. In connection with the sale of Metro International Trade Services (Metro), the firm agreed to provide indemnities to the buyer, which primarily relate to fundamental representations and warranties, and potential liabilities for legal or regulatory proceedings arising out of the conduct of Metro’s business while the firm owned it. 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 December 2018, approximately $1.20 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. Guarantees The table below presents derivatives that meet the definition of a guarantee, securities lending indemnifications and certain other financial guarantees. $ in millions Derivatives Securities lending Other As of December 2018 Carrying Value of Net Liability $ 4,105 $ – $ 38 Maximum Payout/Notional Amount by Period of Expiration 2019 $101,169 $27,869 $1,379 2020 - 2021 77,955 – 2,252 2022 - 2023 17,813 – 2,021 2024 - thereafter 67,613 – 241 Total $264,550 $27,869 $5,893 As of December 2017 Carrying Value of Net Liability $ 3,843 $ $ 37 Maximum Payout/Notional Amount by Period of Expiration 2018 $113,766 $37,959 $ 723 2019 - 2020 59,314 – 1,515 2021 - 2022 24,712 – 1,209 2023 - thereafter 45,343 – 137 Total $243,135 $37,959 $3,584 In the table above: • The maximum payout is based on the notional amount of the contract and does not represent anticipated losses. • Amounts exclude certain commitments to issue standby letters of credit that are included in lending commitments. See the tables in “Commitments” above for a summary of the firm’s commitments. • The carrying value for derivatives included derivative assets of $1.48 billion as of December 2018 and $1.33 billion as of December 2017, and derivative liabilities of $5.59 billion as of December 2018 and $5.17 billion as of December 2017. 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. These derivatives are risk managed together with derivatives that do not meet the definition of a guarantee, and therefore the amounts in the table above do not reflect the firm’s overall risk related to derivative activities. 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 and certain other counterparties. Accordingly, the firm has not included such contracts in the table above. In addition, during 2018, the firm concluded that these conditions have also been met for hedge fund counterparties and, therefore, has not included contracts with these counterparties in the table above. Prior periods have been conformed to the current presentation. See Note 7 for information about credit derivatives that meet the definition of a guarantee, which are not included in the table above. 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. The firm, in its capacity as an agency lender, indemnifies most of its securities lending customers against losses incurred in the event that borrowers do not return securities and the collateral held is insufficient to cover the market value of the securities borrowed. Collateral held by the lenders in connection with securities lending indemnifications was $28.75 billion as of December 2018 and $39.03 billion as of December 2017. Because the contractual nature of these arrangements requires the firm to obtain collateral with a market value that exceeds the value of the securities lent to the borrower, there is minimal performance risk associated with these guarantees. Other Financial Guarantees. In the ordinary course of business, the firm provides other financial guarantees of the obligations of third parties (e.g., standby letters of credit and other guarantees to enable clients to complete transactions and fund-related guarantees). These guarantees represent obligations to make payments to beneficiaries if the guaranteed party fails to fulfill its obligation under a contractual arrangement with that beneficiary. Guarantees of Securities Issued by Trusts. The firm has established trusts, including Goldman Sachs Capital I, the APEX Trusts and other entities for the limited purpose of issuing securities to third parties, lending the proceeds to the firm and entering into contractual arrangements with the firm and third parties related to this purpose. The firm does not consolidate these entities. See Note 16 for further information about the transactions involving Goldman Sachs Capital I and the APEX 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. In the ordinary course of business, the firm indemnifies and guarantees certain service providers, such as clearing and custody agents, trustees and administrators, against specified potential losses in connection with their acting as an agent of, or providing services to, the firm or its affiliates. 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 December 2018 and December 2017. Other Representations, Warranties and Indemnifications. The firm provides representations and warranties to counterparties in connection with a variety of commercial transactions and occasionally indemnifies them against potential losses caused by the breach of those representations and warranties. The firm may also provide indemnifications protecting against changes in or adverse application of certain U.S. tax laws in connection with ordinary-course transactions such as securities issuances, borrowings or derivatives. 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 December 2018 and December 2017. Guarantees of Subsidiaries. Group Inc. fully and unconditionally guarantees the securities issued by GS Finance Corp., a wholly-owned finance subsidiary of the firm. Group Inc. has guaranteed the payment obligations of Goldman Sachs & Co. LLC (GS&Co.) and GS Bank USA, subject to certain exceptions. 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 Framework includes risk-based capital buffers which began to phase in ratably on January 1, 2016, and became fully effective on January 1, 2019. The risk-based capital buffers include the capital conservation buffer, G-SIB G-SIB The firm calculates its CET1, 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 minimum risk-based ratio requirements is assessed. Under the Capital Framework, the firm is also subject to Tier 1 leverage requirements established by the FRB. The Capital Framework also introduced a supplementary leverage ratio (SLR) which became effective on January 1, 2018. Consolidated Regulatory Risk-Based Capital and Leverage Ratios The table below presents the minimum risk-based capital and leverage ratios. As of December 2018 2017 Risk-based capital ratios CET1 ratio 8.3% 7.0% Tier 1 capital ratio 9.8% 8.5% Total capital ratio 11.8% 10.5% Leverage ratios Tier 1 leverage ratio 4.0% 4.0% SLR 5.0% N/A The table below presents information about the risk-based capital ratios. $ in millions Standardized Basel III As of December 2018 CET1 $ 73,116 $ 73,116 Tier 1 capital $ 83,702 $ 83,702 Tier 2 capital $ 14,926 $ 13,743 Total capital $ 98,628 $ 97,445 RWAs $547,910 $558,111 CET1 ratio 13.3% 13.1% Tier 1 capital ratio 15.3% 15.0% Total capital ratio 18.0% 17.5% As of December 2017 CET1 $ 67,110 $ 67,110 Tier 1 capital $ 78,331 $ 78,331 Tier 2 capital $ 14,977 $ 13,899 Total capital $ 93,308 $ 92,230 RWAs $555,611 $617,646 CET1 ratio 12.1% 10.9% Tier 1 capital ratio 14.1% 12.7% Total capital ratio 16.8% 14.9% The table below presents information about the leverage ratios.

The deduction for identifiable intangible assets was fully phased into CET1 in January 2018. As of December 2017, CET1 reflects 80% of the identifiable intangible assets deduction and the remaining 20% was risk weighted. • Deduction for investments in covered funds represents the firm’s aggregate investments in applicable covered funds, excluding investments that are subject to an extended conformance period. See Note 6 for further information about the Volcker Rule. • Other adjustments within CET1 and Tier 1 capital primarily include credit valuation adjustments on derivative liabilities, pension and postretirement liabilities, the overfunded portion of the firm’s defined benefit pension plan obligation net of associated deferred tax liabilities, disallowed deferred tax assets, debt valuation adjustments and other required credit risk-based deductions. The deduction for such items was fully phased into CET1 in January 2018. As of December 2017, CET1 reflects 80% of such deduction. Substantially all of the balance that was not deducted from CET1 as of December 2017 was deducted from Tier 1 capital within other adjustments. Other adjustments within Basel III Advanced Tier 2 capital include eligible credit reserves. • Qualifying subordinated debt is subordinated debt issued by Group Inc. with an original maturity of five years or greater. The outstanding amount of subordinated debt qualifying for Tier 2 capital is reduced upon reaching a remaining maturity of five years. See Note 16 for further information about the firm’s subordinated debt. • Junior subordinated debt represents debt issued to Trust. As of December 2018, 40% of this debt was included in Tier 2 capital and 60% was fully phased out of regulatory capital. As of December 2017, 50% of this debt was included in Tier 2 capital and 50% was fully phased out of regulatory capital. Junior subordinated debt is reduced by the amount of trust preferred securities purchased by the firm and will be fully phased out of Tier 2 capital by 2022 at a rate of 10% per year. See Note 16 for further information about the firm’s junior subordinated debt and trust preferred securities purchased by the firm.

RWAs are calculated in accordance with both the Standardized Capital Rules and the Basel III Advanced Rules. Credit Risk Credit RWAs are calculated based upon 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 Value-at-Risk • VaR is the potential loss in value of inventory positions, as well as certain other financial assets and financial liabilities, due to adverse market movements over a defined time horizon with a specified confidence level. 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-day one-day As a result, there may be differences in the number of VaR exceptions and the amount of daily net revenues calculated for regulatory VaR compared to the amounts calculated for risk management VaR. The firm’s positional losses observed on a single day exceeded 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. Operational Risk Operational RWAs are only required to be included under the Basel III Advanced Rules. The firm utilizes an internal risk-based model to quantify Operational RWAs.

Standardized Credit RWAs as of December 2018 increased by $5.11 billion compared with December 2017, primarily reflecting an increase in commitments, guarantees and loans, principally due to an increase in lending activity. This increase was partially offset by a decrease in securities financing transactions, principally due to reduced exposures. Standardized Market RWAs as of December 2018 decreased by $12.81 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. 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. Year Ended December 2017. Standardized Credit RWAs as of December 2017 increased by $56.82 billion compared with December 2016, primarily reflecting an increase in commitments, guarantees and loans, principally due to increased lending activity. Standardized Market RWAs as of December 2017 increased by $2.12 billion compared with December 2016, primarily reflecting an increase in stressed VaR as a result of increased risk exposures partially offset by decreases in specific risk, as a result of changes in risk exposures, and comprehensive risk, as a result of changes in risk measurements. Basel III Advanced Credit RWAs as of December 2017 increased by $63.23 billion compared with December 2016, primarily reflecting an increase in commitments, guarantees and loans, principally due to increased lending activity. Basel III Advanced Market RWAs as of December 2017 increased by $2.38 billion compared with December 2016, primarily reflecting an increase in stressed VaR as a result of increased risk exposures partially offset by decreases in specific risk, as a result of changes in risk exposures, and comprehensive risk, as a result of changes in risk measurements. Bank Subsidiaries Regulatory Capital Ratios. GS Bank USA, an FDIC-insured, New York State-chartered bank and a member of the Federal Reserve System, is supervised and regulated by the FRB, the FDIC, the New York State Department of Financial Services and the Bureau of Consumer Financial Protection, and is subject to regulatory capital requirements that are calculated in substantially the same manner as those applicable to BHCs. For purposes of assessing the adequacy of its capital, GS Bank USA calculates its capital ratios in accordance with the regulatory capital requirements applicable to state member banks. Those requirements are based on the Capital Framework described above. GS Bank USA is an Advanced approach banking organization under the Capital Framework. 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 meet higher minimum requirements than the minimum ratios in the table below. In order to be considered a “well-capitalized” depository institution, GS Bank USA must meet the SLR requirement of 6.0% or greater, which became effective on January 1, 2018. 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, 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 minimum ratio requirements is assessed. The table below presents GS Bank USA’s minimum risk-based capital and leverage ratios and “well-capitalized” minimum ratios.

The impact of this change was an increase in GS Bank USA’s Basel III Advanced CET1 ratio of approximately 1.6 percentage points. • The Standardized CET1 ratio and Tier 1 capital ratio both remained essentially unchanged from December 2017 to December 2018. • The Standardized Total capital ratio increased from December 2017 to December 2018 primarily due to an increase in Total capital, principally due to the issuance of subordinated debt. • The Basel III Advanced CET1 ratio, Tier 1 capital ratio and Total capital ratio increased from December 2017 to December 2018. 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. • Tier 1 capital and deductions from Tier 1 capital are calculated on a transitional basis as of December 2017. • Tier 1 leverage ratio is calculated as Tier 1 capital divided by average adjusted total assets. • SLR is calculated as Tier 1 capital divided by total leverage exposure. The firm’s principal non-U.S. Other. The deposits of GS Bank USA are insured by the FDIC to the extent provided by law. The FRB requires that GS Bank USA maintain cash reserves with the Federal Reserve Bank of New York. The amount deposited by GS Bank USA at the Federal Reserve Bank of New York was $29.20 billion as of December 2018 and $50.86 billion as of December 2017, which exceeded required reserve amounts by $29.03 billion as of December 2018 and $50.74 billion as of December 2017. 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 $90.22 billion as of December 2018 and $93.88 billion as of December 2017, of which Group Inc. was required to maintain $52.92 billion as of December 2018 and $53.02 billion as of December 2017, of minimum equity capital in its regulated subsidiaries in order to satisfy the regulatory requirements of such subsidiaries.

Earnings Per Share [Abstract]
Earnings Per Common Share	Note 21. Earnings Per Common Share Basic earnings per common share (EPS) is calculated by dividing net earnings applicable to common shareholders by the weighted average number of common shares outstanding and restricted stock units (RSUs) for which no future service is required as a condition to the delivery of the underlying common stock (collectively, basic shares).

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 fees earned from affiliated funds, fees receivable from affiliated funds and the aggregate carrying value of the firm’s interests in affiliated funds. Year Ended December $ in millions 2018 2017 2016 Fees earned from funds $3,571 $2,932 $2,777 As of December $ in millions 2018 2017 Fees receivable from funds $ 610 $ 637 Aggregate carrying value of interests in funds $4,994 $4,993 The firm may periodically determine to waive certain management fees on selected money market funds. Management fees waived were $51 million for 2018 and $98 million for 2017. 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 an outstanding guarantee, as permitted under the Volcker Rule, on behalf of its funds of $154 million as of both December 2018 and December 2017. The firm has voluntarily provided this guarantee 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 December 2018 and December 2017, 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	Income Taxes Tax Legislation The provision for taxes for 2017 reflected an estimated impact of Tax Legislation of $4.40 billion. The $4.40 billion income tax expense included the repatriation tax on undistributed earnings of foreign subsidiaries, the effects of the implementation of a territorial tax system, and the remeasurement of U.S. deferred tax assets at lower enacted tax rates. During 2018, the firm finalized this estimate to reflect the impact of updated information, including subsequent guidance issued by the U.S. Internal Revenue Service (IRS), resulting in a $487 million income tax benefit. 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. The table below presents information about the provision for taxes. Year Ended December $ in millions 2018 2017 2016 Current taxes U.S. federal $ 2,986 $ 320 $1,032 State and local 379 64 139 Non-U.S. 1,302 1,004 1,184 Total current tax expense 4,667 1,388 2,355 Deferred taxes U.S. federal (2,711 ) 5,083 399 State and local 58 157 51 Non-U.S. 8 218 101 Total deferred tax (benefit)/expense (2,645 ) 5,458 551 Provision for taxes $ 2,022 $6,846 $2,906 In the table above: • State and local current taxes in 2017 and 2016 includes the impact of settlements of state and local examinations. • U.S. federal current tax expense and U.S. federal deferred tax expense in 2018 and 2017 includes the impact of Tax Legislation.

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. The table below presents information about deferred tax assets and liabilities, excluding the impact of netting within tax jurisdictions.

The firm also recorded a valuation allowance of $81 million as of December 2018 and $128 million as of December 2017, related to these net operating loss carryforwards. As of December 2018, the U.S. federal net operating loss carryforward was $259 million, the state and local net operating loss carryforward was $1.35 billion, and the foreign net operating loss carryforward was $2.39 billion. If not utilized, the U.S. federal, state and local, and foreign net operating loss carryforwards will begin to expire in 2019. If these carryforwards expire, they will not have a material impact on the firm’s results of operations. As of December 2018, the firm has recorded deferred tax assets of $24 million in connection with foreign tax credit carryforwards and a valuation allowance of $24 million related to these foreign tax credit carryforwards. As of December 2018, the firm has recorded deferred tax assets of $38 million in connection with state and local tax credit carryforwards. If not utilized, the foreign tax credit carryforward will expire in 2028 and the state and local tax credit carryforward will begin to expire in 2020. As of December 2018, the firm did not have any general business credit carryforwards. As of both December 2018 and December 2017, the firm had no U.S. capital loss carryforwards and no related net deferred income tax assets. As of December 2018, the firm had deferred tax assets of $77 million in connection with foreign capital loss carryforwards and a valuation allowance of $77 million related to these capital loss carryforwards. As of December 2017, there were no foreign capital loss carryforwards. The valuation allowance increased by $89 million during 2018 and increased by $41 million during 2017. The increases in both 2018 and 2017 were primarily due to an increase in deferred tax assets from which the firm does not expect to realize any benefit. The firm permanently reinvested eligible earnings of certain foreign subsidiaries. As of December 2018, all U.S. taxes were accrued on these subsidiaries’ distributable earnings, substantially all of which resulted from the Tax Legislation repatriation tax and GILTI. As of December 2017, substantially all U.S. taxes were accrued on these subsidiaries’ earnings and profits as a result of the Tax Legislation repatriation tax. 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. The accrued liability for interest expense related to income tax matters and income tax penalties was $107 million as of December 2018 and $81 million as of December 2017. The firm recognized interest expense and income tax penalties of $18 million for 2018, $63 million for 2017 and $27 million for 2016. It is reasonably possible that unrecognized tax benefits could change significantly during the twelve months subsequent to December 2018 due to potential audit settlements. However, at this time it is not possible to estimate any potential change. The table below presents the changes in the liability for unrecognized tax benefits, which is included in other liabilities. Year Ended or as of December $ in millions 2018 2017 2016 Beginning balance $ 665 $ 852 $ 825 Increases based on tax positions related to the current year 197 94 113 Increases based on tax positions related to prior years 232 101 188 Decreases based on tax positions related to prior years (39 ) (128 ) (88 ) Decreases related to settlements (3 ) (255 ) (186 ) Exchange rate fluctuations (1 ) 1 – Ending balance $1,051 $ 665 $ 852 Related deferred income tax asset 152 75 231 Net unrecognized tax benefit $ 899 $ 590 $ 621 Regulatory Tax Examinations The firm is subject to examination by the 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 U.S. Federal 2011 New York State and City 2011 United Kingdom 2014 Japan 2014 Hong Kong 2011 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 Year Ended December $ in millions 2018 2017 2016 Investment Banking Financial Advisory $ 3,507 $ 3,188 $ 2,932 Equity underwriting 1,646 1,243 891 Debt underwriting 2,709 2,940 2,450 Total Underwriting 4,355 4,183 3,341 Total net revenues 7,862 7,371 6,273 Operating expenses 4,346 3,526 3,437 Pre-tax $ 3,516 $ 3,845 $ 2,836 Institutional Client Services FICC Client Execution $ 5,882 $ 5,299 $ 7,556 Equities client execution 2,835 2,046 2,194 Commissions and fees 3,055 2,920 3,078 Securities services 1,710 1,637 1,639 Total Equities 7,600 6,603 6,911 Total net revenues 13,482 11,902 14,467 Operating expenses 10,351 9,692 9,713 Pre-tax $ 3,131 $ 2,210 $ 4,754 Investing & Lending Equity securities $ 4,455 $ 4,578 $ 2,573 Debt securities and loans 3,795 2,660 1,689 Total net revenues 8,250 7,238 4,262 Provision for credit losses 674 657 182 Operating expenses 3,365 2,796 2,386 Pre-tax $ 4,211 $ 3,785 $ 1,694 Investment Management Management and other fees $ 5,438 $ 5,144 $ 4,798 Incentive fees 830 417 421 Transaction revenues 754 658 569 Total net revenues 7,022 6,219 5,788 Operating expenses 5,267 4,800 4,654 Pre-tax $ 1,755 $ 1,419 $ 1,134 Total net revenues $36,616 $32,730 $30,790 Provision for credit losses 674 657 182 Total operating expenses 23,461 20,941 20,304 Total pre-tax $12,481 $11,132 $10,304 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

Credit Concentrations	12 Months Ended
	Dec. 31, 2018
Risks and Uncertainties [Abstract]
Credit Concentrations	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. Netting and collateral agreements permit the firm to offset receivables and payables with such counterparties and/or enable the firm to obtain collateral on an upfront or contingent basis. The table below presents the credit concentrations in cash instruments included in financial instruments owned. As of December $ in millions 2018 2017 U.S. government and agency obligations $110,616 $76,418 % of total assets 11.9% 8.3% Non-U.S. $ 43,607 $33,956 % of total assets 4.7% 3.7% In addition, the firm had $90.47 billion as of December 2018 and $76.13 billion as of December 2017 of cash deposits held at central banks (included in cash and cash equivalents), of which $29.20 billion as of December 2018 and $50.86 billion as of December 2017 was held at the Federal Reserve Bank of New York. As of both December 2018 and December 2017, the firm did not have credit exposure to any other counterparty that exceeded 2% of total assets. Collateral obtained by the firm related to derivative assets is principally cash and is held by the firm or a third-party custodian. Collateral obtained by the firm related to resale agreements and securities borrowed transactions is primarily U.S. government and agency obligations and non-U.S. The table below presents U.S. government and agency obligations and non-U.S. As of December $ in millions 2018 2017 U.S. government and agency obligations $ 78,828 $96,905 Non-U.S. $ 76,745 $92,850 In the table above: • Non-U.S. • Given that the firm’s primary credit exposure on such transactions is to the counterparty to the transaction, the firm would be exposed to the collateral issuer only in the event of counterparty default.

Legal Proceedings

Legal Proceedings	12 Months Ended

Commitments and Contingencies Disclosure [Abstract]
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 December 2018 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 $1.9 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.

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.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Employee Incentive Plans	Note 29. Employee Incentive Plans 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. Effective January 2017, forfeitures are recorded when they occur. Prior to January 2017, expected forfeitures were estimated and recorded over the vesting period. See Note 3 for information about the adoption of ASU No. 2016-09. Cash dividend equivalents paid on 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 Stock Incentive Plan The firm sponsors a stock incentive plan, The Goldman Sachs Amended and Restated Stock Incentive Plan (2018) (2018 SIP), which provides for grants of RSUs, restricted stock, dividend equivalent rights, incentive stock options, nonqualified stock options, stock appreciation rights, and other share-based awards, each of which may be subject to performance conditions. On May 2, 2018, shareholders approved the 2018 SIP. The 2018 SIP replaced The Goldman Sachs Amended and Restated Stock Incentive Plan (2015) (2015 SIP) previously in effect, and applies to awards granted on or after the date of approval. The 2015 SIP had previously replaced The Goldman Sachs Amended and Restated Stock Incentive Plan (2013) (2013 SIP). As of December 2018, 68.2 million shares were available for grant under the 2018 SIP. If any shares of common stock underlying awards granted under the 2018 SIP, 2015 SIP or 2013 SIP are not delivered due to forfeiture, termination or cancellation or are surrendered or withheld, those shares will become available to be delivered under the 2018 SIP. Shares available for grant are also subject to adjustment for certain changes in corporate structure as permitted under the 2018 SIP. The 2018 SIP is scheduled to terminate on the date of the annual meeting of shareholders that occurs in 2022. Restricted Stock Units The firm grants RSUs (including RSUs subject to performance conditions) to employees, which are generally valued based on the closing price of the underlying shares on the date of grant after taking into account a liquidity discount for any applicable post-vesting and delivery transfer restrictions. RSUs generally vest and underlying shares of common stock deliver (net of required withholding tax) as outlined in the applicable award agreements. Award agreements generally provide that vesting is accelerated in certain circumstances, such as on retirement, death, disability and conflicted employment. Delivery of the underlying shares of common stock, which generally occurs over a three-year period, is conditioned on the grantees satisfying certain vesting and other requirements outlined in the award agreements. The table below presents the 2018 activity related to RSUs.

Accounting Policies [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. Voting interest entities are entities in which (i) the total equity investment at risk is sufficient to enable the entity to finance its activities independently and (ii) the equity holders have the power to direct the activities of the entity that most significantly impact its economic performance, the obligation to absorb the losses of the entity and the right to receive the residual returns of the entity. The usual condition for a controlling financial interest in a voting interest entity is ownership of a majority voting interest. If the firm has a controlling majority voting interest in a voting interest entity, the entity is consolidated. Variable Interest Entities. A VIE is an entity that lacks one or more of the characteristics of a voting interest entity. The firm has a controlling financial interest in a VIE when the firm has a variable interest or interests that provide it with (i) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. See Note 12 for further information about VIEs. Equity-Method Investments. When the firm does not have a controlling financial interest in an entity but can exert significant influence over the entity’s operating and financial policies, the investment is accounted for either (i) under the equity method of accounting or (ii) at fair value by electing the fair value option available under U.S. GAAP. Significant influence generally exists when the firm owns 20% to 50% of the entity’s common stock or 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. The firm has formed numerous investment funds with third-party investors. These funds are typically organized as limited partnerships or limited liability companies for which the firm acts as general partner or manager. Generally, the firm does not hold a majority of the economic interests in these funds. These funds are usually voting interest entities and generally are not consolidated because third-party investors typically have rights to terminate the funds or to remove the firm as general partner or manager. Investments in these funds are generally measured at net asset value (NAV) and are included in financial instruments owned. See Notes 6, 18 and 22 for further information about investments in funds.
Equity-Method Investments	Equity-Method Investments. When the firm does not have a controlling financial interest in an entity but can exert significant influence over the entity’s operating and financial policies, the investment is accounted for either (i) under the equity method of accounting or (ii) at fair value by electing the fair value option available under U.S. GAAP. Significant influence generally exists when the firm owns 20% to 50% of the entity’s common stock or 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.
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, 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. Financial instruments owned and financial instruments sold, but not yet purchased are recorded at fair value either under the fair value option or in accordance with other U.S. GAAP. In addition, the firm has elected to account for certain of its other financial assets and financial liabilities at fair value by electing the fair value option. 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. Fair value gains or losses are generally included in market making for positions in Institutional Client Services and other principal transactions for positions in Investing & Lending. See Notes 5 through 8 for further information about fair value measurements. Revenue from Contracts with Clients. Beginning in January 2018, the firm accounts for revenue earned from contracts with clients for services such as investment banking, investment management, and execution and clearing (contracts with clients) under ASU No. 2014-09, The firm’s net revenues from contracts with clients subject to this ASU represent approximately 50% of the firm’s total net revenues for 2018. This includes approximately 80% of the firm’s investment banking revenues, substantially all of the investment management revenues, and commissions and fees for 2018. See Note 25 for information about the firm’s net revenues by business segment. Investment Banking Advisory. Fees from financial advisory assignments are recognized in revenues when the services related to the underlying transaction are completed under the terms of the assignment. Beginning in January 2018, non-refundable non-refundable Beginning in January 2018, certain expenses associated with financial advisory assignments are recognized when incurred. Client reimbursements for such expenses are included in financial advisory revenues. Prior to January 2018, such expenses were deferred until the related revenue was recognized or the assignment was otherwise concluded and were presented net of client reimbursements. Underwriting. Fees from underwriting assignments are recognized in revenues upon completion of the underlying transaction based on the terms of the assignment. Certain expenses associated with underwriting assignments are deferred until the related revenue is recognized or the assignment is otherwise concluded. Beginning in January 2018, such expenses are presented as operating expenses. Prior to January 2018, such expenses were presented net within underwriting revenues. 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. Management fees for mutual funds are calculated as a percentage of daily net asset value and are received monthly. Management fees for hedge funds and separately managed accounts are calculated as a percentage of 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. Beginning in January 2018, the firm presents such fees in brokerage, clearing, exchange and distribution fees. Prior to January 2018, where the firm was considered an agent to the arrangement, such fees were presented on a net basis in investment management revenues. Incentive Fees. Incentive fees are calculated as a percentage of a fund’s or separately managed account’s return, or excess return above a specified benchmark or other performance target. Incentive fees are generally based on investment performance over a twelve-month period or over the life of a fund. Fees that are based on performance over a twelve-month period are subject to adjustment prior to the end of the measurement period. For fees that are based on investment performance over the life of the fund, future investment underperformance may require fees previously distributed to the firm to be returned to the fund. Beginning in January 2018, 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. Prior to January 2018, incentive fees were recognized only when all material contingencies were resolved. 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 Beginning in January 2018, third-party research costs incurred by the firm in connection with soft-dollar arrangements are presented net within commissions and fees. Prior to January 2018, such costs were presented in brokerage, clearing, exchange and distribution fees. 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 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 December 2018, substantially all of the firm’s future net revenues associated with 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 $10.66 billion as of December 2018 and $10.79 billion as of December 2017. Cash and cash equivalents also included interest-bearing deposits with banks of $119.89 billion as of December 2018 and $99.26 billion as of December 2017. 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 December 2018 and $18.44 billion as of December 2017. 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 $53.81 billion as of December 2018 and $60.11 billion as of December 2017, and receivables from brokers, dealers and clearing organizations of $25.50 billion as of December 2018 and $24.68 billion as of December 2017. 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 $3.83 billion as of December 2018 and $4.63 billion as of December 2017 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 December 2018 and December 2017, 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 December 2018 and December 2017. 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, beginning in January 2018, also includes 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. As of December 2018, the firm’s receivables from contracts with clients were $1.94 billion and contract assets were not material.
Customer and Other Payables, Policy	Customer and Other Payables Customer and other payables included payables to customers and counterparties of $173.99 billion as of December 2018 and $171.50 billion as of December 2017, and payables to brokers, dealers and clearing organizations of $6.24 billion as of December 2018 and $6.67 billion as of December 2017. 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 December 2018 and December 2017. 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.
Foreign Currency Translation, Policy	Foreign Currency Translation Assets and liabilities denominated in non-U.S. non-U.S.
Recent Accounting Developments	Recent Accounting Developments Revenue from Contracts with Customers (ASC 606). In May 2014, the FASB issued ASU No. 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). In addition, net revenues and operating expenses were both higher by approximately $300 million for 2018, due to the changes in the presentation of certain costs from a net presentation within revenues to a gross basis. Recognition and Measurement of Financial Assets and Financial Liabilities (ASC 825). In January 2016, the FASB issued ASU No. 2016-01, In January 2016, the firm early adopted this ASU for the requirements related to DVA and reclassified the cumulative DVA, a gain of $305 million (net of tax), from retained earnings to accumulated other comprehensive loss. The adoption of the remaining provisions of the ASU in January 2018 did not have a material impact on the firm’s financial condition, results of operations or cash flows. Leases (ASC 842). In February 2016, the FASB issued ASU No. 2016-02, right-of-use right-of-use The firm adopted this ASU in January 2019 under a modified retrospective approach. The impact of adopting this ASU was a gross up of $1.77 billion on the firm’s consolidated statements of financial condition and an increase to retained earnings of $12 million (net of tax) as of January 1, 2019. Improvements to Employee Share-Based Payment Accounting (ASC 718). In March 2016, the FASB issued ASU No. 2016-09, paid-in The firm adopted the ASU in January 2017 and subsequent to the adoption, the tax effect related to the settlement of share-based awards is recognized in the statements of earnings rather than directly to additional paid-in In addition, the ASU modifies the classification of certain share-based payment activities within the statements of cash flows. Upon adoption, the firm reclassified amounts related to such activities within the consolidated statements of cash flows, on a retrospective basis. Measurement of Credit Losses on Financial Instruments (ASC 326). In June 2016, the FASB issued ASU No. 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 the financial 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 beginning in January 2019. The firm plans to adopt this ASU on January 1, 2020. Expected credit losses, including losses on off-balance-sheet The firm has substantially completed development of credit loss models for its significant loan portfolios and is in the process of validating data inputs to these models, while continuing to develop the policies, systems and controls that will be required to implement CECL. The firm currently expects to begin testing of these models in the first half of 2019. The firm currently expects that its allowance for credit losses will likely increase when CECL is adopted as the allowance will cover expected credit losses over the full expected life of the loan portfolios and will also take into account expected changes in future economic conditions. 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. The extent of the impact of adoption of this ASU on the firm’s financial condition, results of operations and cash flows will depend on, among other things, the economic environment, and the size and type of loan portfolios held by the firm on the date of adoption. Classification of Certain Cash Receipts and Cash Payments (ASC 230). In August 2016, the FASB issued ASU No. 2016-15, The firm adopted this ASU in January 2018 under a retrospective approach. The impact for 2017 was an increase of $485 million to net cash used for operating activities, a decrease of $477 million to net cash used for investing activities and an increase of $8 million to net cash provided by financing activities. The impact for 2016 was a decrease of $406 million to net cash provided by operating activities, an increase of $405 million to net cash provided by investing activities and an increase of $1 million to net cash provided by financing activities. Clarifying the Definition of a Business (ASC 805). In January 2017, the FASB issued ASU No. 2017-01, The firm adopted this ASU in January 2018 under a prospective approach. Adoption of the ASU did not have a material impact on the firm’s financial condition, results of operations or cash flows. The firm expects that fewer transactions will be treated as acquisitions (or disposals) of businesses as a result of adopting this ASU. Simplifying the Test for Goodwill Impairment (ASC 350). In January 2017, the FASB issued ASU No. 2017-04, The firm early adopted this ASU in the fourth quarter of 2017. Adoption of the ASU did not have a material impact on the results of the firm’s goodwill impairment test. Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets (ASC 610-20). In February 2017, the FASB issued ASU No. 2017-05, (Subtopic 610-20) — The firm adopted this ASU in January 2018 under a modified retrospective approach. Adoption of the ASU did not have an impact on the firm’s financial condition, results of operations or cash flows. Targeted Improvements to Accounting for Hedging Activities (ASC 815). In August 2017, the FASB issued ASU No. 2017-12, The firm early adopted this ASU in January 2018 under a modified retrospective approach for hedge accounting treatment, and under a prospective approach for the amended disclosure requirements. Adoption of this ASU did not have a material impact on the firm’s financial condition, results of operations or cash flows. See Note 7 for further information. Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (ASC 220). In February 2018, the FASB issued ASU No. 2018-02, 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 financial condition, results of operations or cash flows. Changes to the Disclosure Requirements for Fair Value Measurement (ASC 820). In August 2018, the FASB issued ASU No. 2018-13,
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. Inputs are unadjusted quoted prices in active markets to which the firm had access at the measurement date for identical, unrestricted assets or liabilities. Level 2. Inputs to valuation techniques are observable, either directly or indirectly. Level 3. One or more inputs to valuation techniques are significant and unobservable. 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. Loans and securities backed by commercial real estate are directly or indirectly collateralized by a single commercial real estate property or a portfolio of properties, and may include tranches of varying levels of subordination. Significant inputs are generally determined based on relative value analyses and include: • 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. Loans and securities backed by residential real estate are directly or indirectly collateralized by portfolios of residential real estate and may include tranches of varying levels of subordination. Significant inputs are generally determined based on relative value analyses, which incorporate comparisons to instruments with similar collateral and risk profiles. Significant inputs include: • 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. Corporate debt instruments includes corporate loans and debt securities. Significant inputs for corporate debt instruments are generally determined based on relative value analyses, which incorporate comparisons both to prices of credit default swaps that reference the same or similar underlying instrument or entity and to other debt instruments for the same issuer for which observable prices or broker quotations are available. Significant inputs include: • 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. Equity securities includes private equity securities and convertible debentures. Recent third-party completed or pending transactions (e.g., merger proposals, tender offers, debt restructurings) are considered to be the best evidence for any change in fair value. When these are not available, the following valuation methodologies are used, as appropriate: • 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. Other cash instruments includes U.S. government and agency obligations, 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 derivative was transferred into 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 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% or greater and a slope between 80% and 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. Beginning in January 2018, in accordance with ASU No. 2017-12
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. Loans receivable (excluding PCI loans) are determined to be impaired when it is probable that the firm will not collect all principal and interest due under the contractual terms. At that time, loans are generally placed on nonaccrual status and all accrued but uncollected interest is reversed against interest income and interest subsequently collected is recognized on a cash basis to the extent the loan balance is deemed collectible. Otherwise, all cash received is used to reduce the outstanding loan balance. A loan is considered past due when a principal or interest payment has not been made according to its contractual terms. 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 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 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. • 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. Substantially all of the firm’s identifiable intangible assets are considered to have finite useful lives and are amortized over their estimated useful lives generally using the straight-line method. Impairments The firm tests property, leasehold improvements and equipment, identifiable intangible assets and other assets 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 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 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 if the carrying value of the asset exceeds its estimated fair value.
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.
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	• Held for investment lending commitments are accounted for on an accrual basis. • 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 relates to the firm’s Investing & Lending segment.
Property, Plant and Equipment, Operating Lease Policy	Operating leases include office space held in excess of current requirements. Rent expense relating to space held for growth is included in occupancy expenses. The firm records a liability, based on the fair value of the remaining lease rentals reduced by any potential or existing sublease rentals, for leases where the firm has ceased using the space and management has concluded that the firm will not derive any future economic benefits. Costs to terminate a lease before the end of its term are recognized and measured at fair value on termination.
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 and certain other counterparties.
Earnings Per Share Policy	Basic earnings per common share (EPS) is calculated by dividing net earnings applicable to common shareholders by the weighted average number of common shares outstanding and restricted stock units (RSUs) for which no future service is required as a condition to the delivery of the underlying common stock (collectively, basic shares). Diluted EPS includes the determinants of basic EPS and, in addition, reflects the dilutive effect of the common stock deliverable for stock options and for RSUs for which future service is required as a condition to the delivery of the underlying common stock.
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
Share-based Compensation, Policies	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. Effective January 2017, forfeitures are recorded when they occur. Prior to January 2017, expected forfeitures were estimated and recorded over the vesting period. See Note 3 for information about the adoption of ASU No. 2016-09. Cash dividend equivalents paid on 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 The firm grants RSUs (including RSUs subject to performance conditions) to employees, which are generally valued based on the closing price of the underlying shares on the date of grant after taking into account a liquidity discount for any applicable post-vesting and delivery transfer restrictions.

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, Cash Instruments, Measurement Inputs, Disclosure	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 $ in millions 2018 2017 Loans and securities backed by commercial real estate Level 3 assets $1,019 $1,126 Yield 6.9% to 22.5% (12.4% ) 4.6% to 22.0% (13.4% ) Recovery rate 9.7% to 78.4% (42.9% ) 14.3% to 89.0% (43.8% ) Duration (years) 0.4 to 7.1 (3.7 ) 0.8 to 6.4 (2.1 ) Loans and securities backed by residential real estate Level 3 assets $663 $668 Yield 2.6% to 19.3% (9.2% ) 2.3% to 15.0% (8.3% ) Cumulative loss rate 8.3% to 37.7% (19.2% ) 12.5% to 43.0% (21.8% ) Duration (years) 1.4 to 14.0 (6.7 ) 0.7 to 14.0 (6.9 ) Corporate debt instruments Level 3 assets $4,224 $3,270 Yield 0.7% to 32.3% (11.9% ) 3.6% to 24.5% (12.3% ) Recovery rate 0.0% to 78.0% (57.8% ) 0.0% to 85.3% (62.8% ) Duration (years) 0.4 to 13.5 (3.4 ) 0.5 to 7.6 (3.2 ) Equity securities Level 3 assets $10,725 $9,904 Multiples 1.0x to 23.6x (8.1x ) 1.1x to 30.5x (8.9x ) Discount rate/yield 6.5% to 22.1% (14.3% ) 3.0% to 20.3% (14.0% ) Capitalization rate 3.5% to 12.3% (6.1% ) 4.3% to 12.0% (6.1% ) Other cash instruments Level 3 assets $596 $427 Yield 4.1% to 11.5% (9.2% ) 4.0% to 11.7% (8.4% ) Duration (years) 2.2 to 4.8 (2.8 ) 3.5 to 11.4 (5.1 ) 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 December 2018 and December 2017. 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.
Cash Instruments, Level 3 Rollforward	The table below presents a summary of the changes in fair value for level 3 cash instrument assets and liabilities. Year Ended December $ in millions 2018 2017 Total cash instrument assets Beginning balance $15,395 $18,035 Net realized gains/(losses) 501 419 Net unrealized gains/(losses) 816 1,144 Purchases 2,286 1,635 Sales (2,184 ) (3,315 ) Settlements (2,595 ) (2,265 ) Transfers into level 3 5,149 2,405 Transfers out of level 3 (2,141 ) (2,663 ) Ending balance $17,227 $15,395 Total cash instrument liabilities Beginning balance $ (68 ) $ (62 ) Net realized gains/(losses) 6 (8 ) Net unrealized gains/(losses) (7 ) (28 ) Purchases 41 97 Sales (26 ) (20 ) Settlements 8 (32 ) Transfers into level 3 (7 ) (18 ) Transfers out of level 3 4 3 Ending balance $ (49 ) $ (68 ) In the table above: • Changes in fair value are presented for all cash instrument assets and liabilities that are classified in level 3 as of the end of the period. • Net unrealized gains/(losses) relates to instruments that were still held at period-end. • Purchases includes originations and secondary purchases. • 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. • 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.

As of December 2017, the impact of this change would have been a reduction in gross interest rate derivative assets of $3.6 billion and gross interest rate derivative liabilities of $1.9 billion, and a corresponding decrease in counterparty and cash collateral netting, with no impact to the consolidated statements of financial condition. • On November 19, 2018, a clearing organization revised its rules to calculate notional amounts for certain exchange-traded derivative contracts. The impact of this rule change, as of the effective date, was a decrease in the notional amounts of derivative contracts of approximately $7 trillion, substantially all of which related to interest rate derivatives, with no change to their fair value.

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.

For the Three Months $ in millions 2018 2017 Tier 1 capital $ 27,467 $ 25,343 Average adjusted total assets $188,606 $168,842 Total leverage exposure $368,062 $345,734 Tier 1 leverage ratio 14.6% 15.0% SLR 7.5% 7.3% In the tables above: • Each of the risk-based capital ratios calculated in accordance with the Standardized Capital Rules was lower than that calculated in accordance with the Basel III Advanced Rules and therefore the Standardized Capital ratios were the ratios that applied to GS Bank USA as of both December 2018 and December 2017. • The minimum risk-based capital ratios as of December 2018 reflect (i) the 75% phase-in • The minimum risk-based capital ratios as of December 2017 reflect (i) the 50% phase-in • Beginning in the fourth quarter of 2018, the firm’s default experience was incorporated into the determination of probability of default for the calculation of Basel III Advanced RWAs. The impact of this change was an increase in GS Bank USA’s Basel III Advanced CET1 ratio of approximately 1.6 percentage points. • The Standardized CET1 ratio and Tier 1 capital ratio both remained essentially unchanged from December 2017 to December 2018. • The Standardized Total capital ratio increased from December 2017 to December 2018 primarily due to an increase in Total capital, principally due to the issuance of subordinated debt. • The Basel III Advanced CET1 ratio, Tier 1 capital ratio and Total capital ratio increased from December 2017 to December 2018. 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. • Tier 1 capital and deductions from Tier 1 capital are calculated on a transitional basis as of December 2017. • Tier 1 leverage ratio is calculated as Tier 1 capital divided by average adjusted total assets. • SLR is calculated as Tier 1 capital divided by total leverage exposure.
