Summary of significant accounti

Summary of significant accounting policies	1 Summary of significant accounting policies The accompanying consolidated financial statements of Credit Suisse Group AG (the Group) are prepared in accordance with accounting principles generally accepted in the US (US GAAP) and are stated in Swiss francs (CHF). The financial year for the Group ends on December 31. Certain reclassifications have been made to the prior year’s consolidated financial statements to conform to the current presentation which had no impact on net income/(loss) or total shareholders’ equity. In preparing the consolidated financial statements, management is required to make estimates and assumptions including, but not limited to, the fair value measurements of certain financial assets and liabilities, the allowance for loan losses, the evaluation of variable interest entities (VIEs), the impairment of assets other than loans, recognition of deferred tax assets, tax uncertainties, pension liabilities and various contingencies. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the dates of the consolidated balance sheets and the reported amounts of revenues and expenses during the reporting period. While management evaluates its estimates and assumptions on an ongoing basis, actual results could differ materially from management’s estimates. Market conditions may increase the risk and complexity of the judgments applied in these estimates. Principles of consolidation The consolidated financial statements include the financial statements of the Group and its subsidiaries. The Group’s subsidiaries are entities in which it holds, directly or indirectly, more than 50% of the voting rights or where it exercises control. The Group consolidates limited partnerships in cases where it is the general partner and the limited partners do not have either substantive kick out rights and/or substantive participating rights or is a limited partner with substantive rights to kick out the general partner or dissolve the partnership and participate in significant decisions made in the ordinary course of business. The Group also consolidates VIEs if the Group is the primary beneficiary in accordance with Accounting Standards Codification (ASC) Topic 810 – Consolidation. The effects of material intercompany transactions and balances have been eliminated. Where a Group subsidiary is determined to be an investment company as defined by ASC Topic 946 – Financial Services – Investment Companies, interests in other entities held by this Group subsidiary are not consolidated and are carried at fair value. Group entities that qualify as broker-dealer entities as defined by ASC Topic 940 – Financial Services – Brokers and Dealers do not consolidate investments in voting interest entities that would otherwise qualify for consolidation when the investment is held on a temporary basis for trading purposes. In addition, subsidiaries that are strategic components of a broker-dealer’s operations are consolidated regardless of holding intent. Foreign currency translation Transactions denominated in currencies other than the functional currency of the related entity are recorded by remeasuring them in the functional currency of the related entity using the foreign exchange rate on the date of the transaction. As of the dates of the consolidated balance sheets, monetary assets and liabilities are reported using the year-end spot foreign exchange rates. Foreign exchange rate differences are recorded in the consolidated statements of operations. Non-monetary assets and liabilities are recorded using the historic exchange rate. For the purpose of consolidation, the assets and liabilities of Group companies with functional currencies other than the Swiss franc are translated into Swiss franc equivalents using year-end spot foreign exchange rates, whereas revenues and expenses are translated at weighted average foreign exchange rates for the period. Translation adjustments arising from consolidation are included in accumulated other comprehensive income/(loss) (AOCI) within total shareholders’ equity. Cumulative translation adjustments are released from AOCI and recorded in the consolidated statements of operations when the Group disposes and loses control of a consolidated foreign subsidiary. Fair value measurement and option The fair value measurement guidance establishes a single authoritative definition of fair value and sets out a framework for measuring fair value. The fair value option creates an alternative measurement treatment for certain financial assets and financial liabilities. The fair value option can be elected at initial recognition of the eligible item or at the date when the Group enters into an agreement which gives rise to an eligible item (e.g., a firm commitment or a written loan commitment). If not elected at initial recognition, the fair value option can be applied to an item upon certain triggering events that give rise to a new basis of accounting for that item. The application of the fair value option to a financial asset or a financial liability does not change its classification on the balance sheet and the election is irrevocable. Changes in fair value resulting from the election are recorded in trading revenues. > Refer to “Fair value option” in Note 36 – Financial instruments for further information. Cash and due from banks Cash and due from banks consists of currency on hand, demand deposits with banks or other financial institutions and cash equivalents. Cash equivalents are defined as short-term, highly liquid instruments with original maturities of three months or less, which are held for cash management purposes. Restricted cash is any cash or cash equivalent recorded in cash and due from banks subject to restrictions imposed by a governmental or other regulatory agency that require the Group to set aside specified amounts of cash as reserves against transactions and time deposits. Reverse repurchase and repurchase agreements Purchases of securities under agreements to resell (reverse repurchase agreements) and securities sold under agreements to repurchase (repurchase agreements) do not constitute economic sales; therefore, they are treated as collateralized financing transactions, which are carried in the consolidated balance sheet at the amount of cash disbursed or received, respectively. Reverse repurchase agreements are recorded as collateralized assets while repurchase agreements are recorded as liabilities. The underlying securities sold continuing to be recognized in trading assets or investment securities. The fair value of securities to be repurchased and resold is monitored on a daily basis, and additional collateral is obtained as needed to protect against credit exposure. Assets and liabilities recorded under these agreements are accounted for on one of two bases, the accrual basis or the fair value basis. Under the accrual basis, interest earned on reverse repurchase agreements and interest incurred on repurchase agreements are reported in interest and dividend income and interest expense, respectively. The Group elects to apply the fair value option to selected agreements pursuant to ASC Topic 825 – Financial Instruments. Under such circumstances, the change in fair value is reported in trading revenues. Accrued interest income and expense are recorded in the same manner as under the accrual method. Reverse repurchase and repurchase agreements may be netted if they are with the same counterparty; have the same maturity date; settle through the same qualifying clearing institution and subject to a right of offset allowed by a legally enforceable master netting agreement or a central counterparty’s clearing rules. Securities lending and borrowing transactions Securities borrowed and securities loaned that are cash-collateralized are included in the consolidated balance sheets at amounts equal to the cash advanced or received. If securities received as collateral in a securities lending and borrowing transaction may be sold or repledged, they are recorded as securities received as collateral in the consolidated balance sheet and a corresponding liability to return the security is recorded. Securities lending transactions against non-cash collateral in which the Group has the right to resell or repledge the collateral received are recorded at the fair value of the collateral initially received. For securities lending transactions, the Group receives cash or securities collateral in an amount generally in excess of the market value of securities lent. The Group monitors the fair value of securities borrowed and loaned on a daily basis with additional collateral obtained as necessary. Fees and interest received or paid are recorded in interest and dividend income and interest expense, respectively, on an accrual basis. If the fair value basis of accounting is elected, any resulting change in fair value is reported in trading revenues. Accrued interest income and expense are recorded in the same manner as under the accrual method. Transfers of financial assets Transfers of financial assets may involve the sale of these assets to special purpose entities (SPEs), which in turn issue securities to investors. The Group values its beneficial interests in such SPEs at fair value using quoted market prices, if such positions are traded on an active exchange or financial models that incorporate observable and unobservable inputs. > Refer to “Note 35 – Transfers of financial assets and variable interest entities” for further information on the Group’s transfer activities. Trading assets and liabilities Trading assets and liabilities include debt securities, marketable equity instruments, derivative instruments, certain loans held in broker-dealer entities, commodities and precious metals. Items included in the trading portfolio are carried at fair value and classified as held for trading purposes based on management’s intent. Regular-way security transactions are recorded on a trade-date basis. Unrealized and realized gains and losses on trading positions are recorded in trading revenues. Derivatives Freestanding derivative contracts are carried at fair value in the consolidated balance sheets regardless of whether these instruments are held for trading or risk management purposes. Commitments to originate mortgage loans that will be held for sale are considered derivatives for accounting purposes. When derivative features embedded in certain contracts that meet the definition of a derivative are not considered clearly and closely related to the host contract, either the embedded feature is accounted for separately at fair value or the entire contract, including the embedded feature, is accounted for at fair value. In both cases, changes in fair value are recorded in the consolidated statements of operations. If separated for measurement purposes, the derivative is recorded in the same line item in the consolidated balance sheets as the host contract. Derivatives classified as trading assets and liabilities include those held for trading purposes and those used for risk management purposes that do not qualify for hedge accounting. Derivatives held for trading purposes arise from proprietary trading activity and from customer-based activity. Realized gains and losses, changes in unrealized gains and losses and interest flows are included in trading revenues. Derivative contracts designated and qualifying as fair value hedges, cash flow hedges or net investment hedges are reported as other assets or other liabilities. The fair value of exchange-traded derivatives is typically derived from observable market prices and/or observable market parameters. Fair values for over-the-counter (OTC) derivatives are determined on the basis of proprietary models using various input parameters. Derivative contracts are recorded on a net basis per counterparty where a right to offset exists under an enforceable master netting agreement or a central counterparty’s clearing rules. Where no such rights exist, fair values are recorded on a gross basis. Where hedge accounting is applied, the Group formally documents all relationships between hedging instruments and hedged items, including the risk management objectives and strategy for undertaking hedge transactions. At inception of a hedge and on an ongoing basis, the hedge relationship is formally assessed to determine whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flows of hedged items attributable to the hedged risk. The Group discontinues hedge accounting prospectively in the following circumstances: (i) the derivative is no longer effective in offsetting changes in the fair value or cash flows of a hedged item (including forecasted transactions); (ii) the derivative expires or is sold, terminated or exercised; (iii) the derivative is no longer designated as a hedging instrument because it is unlikely that the forecasted transaction will occur; or (iv) the designation of the derivative as a hedging instrument is otherwise no longer appropriate. For derivatives that are designated and qualify as fair value hedges, the carrying values of the underlying hedged items are adjusted to fair value for the risk being hedged. Changes in the fair value of these derivatives are recorded in the same line item of the consolidated statements of operations used to present the changes in the fair value of the hedged item. When the Group discontinues fair value hedge accounting because it determines that the derivative no longer qualifies as an effective hedge, the derivative will continue to be carried in the consolidated balance sheets at its fair value, and the hedged asset or liability will no longer be adjusted for changes in fair value attributable to the hedged risk. Interest-related fair value adjustments made to the underlying hedged items will be amortized to the consolidated statements of operations over the remaining life of the hedged item. Any unamortized interest-related fair value adjustment is recorded in the consolidated statements of operations upon sale or extinguishment of the hedged asset or liability, respectively. Any other fair value hedge adjustments remain part of the carrying amount of the hedged asset or liability and are recognized in the consolidated statements of operations upon disposition of the hedged item as part of the gain or loss on disposition. For hedges of the variability of cash flows from forecasted transactions and floating rate assets or liabilities, the change in the fair value of a designated derivative is recorded in AOCI. These amounts are reclassified into the line item in the consolidated statements of operations in which the hedged item is recorded when the variable cash flow from the hedged item impacts earnings (for example, when periodic settlements on a variable rate asset or liability are recorded in the consolidated statements of operations or when the hedged item is disposed of). When hedge accounting is discontinued on a cash flow hedge, the net gain or loss will remain in AOCI and be reclassified into the consolidated statements of operations in the same period or periods during which the formerly hedged transaction is reported in the consolidated statements of operations. When the Group discontinues hedge accounting because it is probable that a forecasted transaction will not occur within the specified date or period plus two months, the derivative will continue to be carried in the consolidated balance sheets at its fair value, and gains and losses that were previously recorded in AOCI will be recognized immediately in the consolidated statements of operations. For hedges of a net investment in a foreign operation, the change in the fair value of the hedging derivative is recorded in AOCI. The Group uses the forward method of determining effectiveness for net investment hedges, which results in the time value portion of a foreign currency forward being reported in AOCI. Investment securities Investment securities include debt securities classified as held-to-maturity and debt securities classified as available-for-sale. Regular-way security transactions are recorded on a trade-date basis. Debt securities where the Group has the positive intent and ability to hold such securities to maturity are classified as such and are carried at amortized cost, net of any unamortized premium or discount. Debt securities classified as held-to-maturity require an assessment of the current expected credit loss (CECL) at the reporting date. Debt securities classified as available-for-sale are carried at fair value. Unrealized gains and losses, which represent the difference between fair value and amortized cost, are recorded in AOCI. Amounts reported in AOCI are net of income taxes. Debt securities classified as available-for-sale are impaired if there is a decline in fair value below amortized cost basis. If the Group intends to sell an impaired security or more likely than not will be required to sell such a security before recovering its amortized cost basis, the entire difference between the amortized cost basis and fair value is recognized as a credit loss. However, if the Group does not intend to sell and is not likely to be required to sell, an assessment is made if a decline in fair value of the security is due to credit-related factors or non-credit related factors. Credit-related impairment is recognized in earnings by recording an allowance for credit losses. Any portion of the unrealized loss that relates to non-credit related factors is recognized in AOCI, net of income taxes. Amortization of premiums or discounts for debt securities is recorded in interest and dividend income using the effective yield method through the maturity date of the security. Other investments Other investments include equity method investments, equity securities without a readily determinable fair value, such as hedge funds, private equity securities and certain investments in non-marketable mutual funds for which the Group has neither significant influence nor control over the investee, and real estate held-for-investment. Equity method investments are investments for which the Group has the ability to significantly influence the operating and financial policies. Significant influence is typically characterized by ownership of 20% to 50% of the voting stock or in-substance common stock of a corporation or 3% 5% Equity securities without a readily determinable fair value are carried at fair value, net asset value practical expedient to estimate fair value or at cost less impairment, adjusted for observable price changes (measurement alternative). Memberships in exchanges are reported at cost, less impairment. Equity securities without a readily determinable fair value held by the Group’s subsidiaries that are determined to be investment companies as defined by ASC Topic 946 – Financial Services – Investment Companies are carried at fair value, with changes in fair value recorded in other revenues. Equity method investments and equity securities without a readily determinable fair value held by subsidiaries that are within the scope of ASC Topic 940 – Financial Services – Brokers and Dealers are measured at fair value and reported in trading assets when the intent of the broker-dealer entity is to hold the asset temporarily for trading purposes. Changes in fair value are reported in trading revenues. Equity securities without a readily determinable fair value include investments in entities that regularly calculate net asset value per share or its equivalent, with changes in fair value recorded in other revenue. Real estate held-for-investment purposes is carried at cost less accumulated depreciation and is depreciated over its estimated useful life, generally 40 to 67 years. Land that is classified as real estate held-for-investment purposes is carried at historical cost and is not depreciated. Real estate held-for-investment purposes is tested for impairment annually, or more frequently, if events or changes in circumstances indicate that the carrying amount may not be recoverable. For real estate held-for-investment purposes, the fair values were measured based on either discounted cash flow analyses or external market appraisals. Recognition of an impairment on such assets establishes a new cost base, which is not adjusted for subsequent recoveries in value. Loans Loans held-to-maturity Loans which the Group intends to hold until maturity are carried at outstanding principal balances plus accrued interest, net of the following items: unamortized premiums, discounts on purchased loans, deferred loan origination fees and direct loan origination costs on originated loans. Interest income is accrued on the unpaid principal balance and net deferred premiums/discounts and fees/costs are amortized as an adjustment to the loan yield over the term of the related loans. A loan is classified as non-performing and thus considered credit impaired no later than when the contractual payments of principal and/or interest are more than 90 days past due except for subprime residential loans which are classified as non-performing no later than when the contractual payments of principal and/or interest are more than 120 days past due. The additional 30 days ensure that these loans are not incorrectly assessed as non-performing during the time when servicing of them typically is being transferred. However, management may determine that a loan should be classified as non-performing notwithstanding that contractual payments of principal and/or interest are less than 90 days past due or, in the case of subprime residential loans, 120 days past due. In addition, the Group continues to add accrued interest receivable to the loan’s balance for collection purposes; however, a credit provision is recorded, resulting in no interest income recognition. A loan can be further downgraded to non-interest-earning when the collection of interest is considered so doubtful that further accrual of interest is deemed inappropriate. Generally, non-performing loans and non-interest-earning loans may be restored to performing status only when delinquent principal and interest are brought up to date in accordance with the terms of the loan agreement and when certain performance criteria are met. Interest collected on non-performing loans and non-interest-earning loans is accounted for using the cash basis or the cost recovery method or a combination of both. Amortization of deferred fees and premiums and discounts ceases while a loan is deemed to be non-performing or non-interest-earning. Loans that are modified in a troubled debt restructuring are reported as restructured loans. Generally, a restructured loan would have been considered credit-impaired prior to the restructuring. Loans modified in a troubled debt restructuring are no longer considered credit-impaired in the years following the restructuring if the restructured loan carries an interest rate that is equal to or greater than the rate the Group was willing to accept at the time of the restructuring for a loan with comparable risk and the loan is not credit-impaired based on the terms specified by the restructuring agreement. Loans that have been restructured in a troubled debt restructuring and are performing according to the new terms continue to accrue interest. Loan restructurings may include the receipt of assets in satisfaction of the loan, the modification of loan terms (e.g., reduction of interest rates, extension of maturity dates at a stated interest rate lower than the current market rate for new loans with similar risk, or reduction in principal amounts and/or accrued interest balances) or a combination of both. Potential problem loans are credit-impaired loans where contractual payments have been received according to schedule, but where doubt exists as to the collection of future contractual payments. Potential problem loans continue to accrue interest. > Refer to “Note 19 – Loans” for further information. Credit losses on financial instruments measured at amortized cost The credit loss requirements apply to financial assets measured at amortized cost including loans held-to-maturity, net investments in leases as a lessor as well as off-balance sheet credit exposures, such as irrevocable loan commitments, and credit guarantees. The credit loss requirements are based on a forward-looking, lifetime CECL model by incorporating reasonable and supportable forecasts of future economic conditions available at the reporting date. The CECL amounts are estimated over the contractual term of the financial assets taking into account the effect of prepayments. This requires considerable judgment over how changes in macroeconomic factors as well as changes in forward-looking borrower-specific characteristics will affect the CECL amounts. The Group measures expected credit losses of financial assets on a collective (pool) basis when similar risk characteristics exist. For financial assets that do not share similar risk characteristics, expected credit losses are evaluated on an individual basis. CECL amounts are probability-weighted estimates of potential credit losses based on historical frequency, current trends and conditions as well as forecasted macroeconomic factors, such as gross domestic product, unemployment rates and interest rates. For financial assets that are performing at the reporting date, the allowance for credit losses is generally measured using a probability of default/loss given default approach under which both probability of default (PD), loss given default (LGD) and exposure at default (EAD) are estimated. For financial assets that are credit-impaired at the reporting date, the Group generally applies a discounted cash flow approach to determine the difference between the gross carrying amount and the present value of estimated future cash flows. An allowance for credit losses is deducted from the amortized cost basis of the financial asset. Changes in the allowance for credit losses are recorded in the consolidated statement of operations in provision for credit losses or, if related to provisions on past due interest, in net interest income. For undrawn irrevocable loan commitments, the present value is calculated based on the difference between the contractual cash flows that are due to the Group if the commitment is drawn and the cash flows that the Group expects to receive, in order to estimate the provision for expected credit losses. For credit guarantees, expected credit losses are recognized for the contingency of the credit guarantee. Provisions for off-balance sheet credit exposures are recognized as a provision in other liabilities in the consolidated balance sheets. Write-off of a financial asset occurs when it is considered certain that there is no possibility of recovering the outstanding principal. If the amount of loss on write-off is greater than the accumulated allowance for credit losses, the difference results in an additional credit loss. The additional credit loss is first recognized as an addition to the allowance; the allowance is then applied against the gross carrying amount. Any repossessed collateral is initially measured at fair value. The subsequent measurement depends on the nature of the collateral. Any uncollectible accrued interest receivable is written off by reversing the related interest income. Expected recoveries on financial assets previously written off or assessed/planned to be written off have to be reflected in the allowance for credit losses; for this purpose, the amount of expected recoveries cannot exceed the aggregate amounts previously written off or assessed/planned to be written off. Accordingly, expected recoveries from financial assets previously written off may result in an overall negative allowance for credit loss balance. Prior to January 2020, the allowance for credit losses reflected probable incurred credit losses. > Refer to “Note 20 – Financial instruments measured at amortized cost and credit losses” for further information. Loans held-for-sale Loans, which the Group intends to sell in the foreseeable future, are considered held-for-sale and are carried at the lower of amortized cost or market value determined on either an individual method basis, or in the aggregate for pools of similar loans if sold or securitized as a pool. Loans held-for-sale are included in other assets. Adjustments to the lower of amortized cost basis or fair value are presented as a valuation allowance and recorded in other revenue. Purchased impaired loans Purchased loans for which it is probable at acquisition that all contractually required payments will not be received are recorded at their net purchase price and no allowances are carried over. The excess of the estimated cash flows to be collected over the amount paid is accreted into interest income over the estimated recovery period when reasonable estimates can be made about the timing and amount of recovery. The Group does not consider such loans to be impaired at the time of acquisition. Such loans are deemed impaired only if the Group’s estimate of cash to be received decreases below the estimate at the time of acquisition. Increases in the estimated expected recovery are recorded as a reversal of allowances, if any, and then recognized as an adjustment of the effective yield of the loan. Loans held at fair value under the fair value option Loans and loan commitments for which the fair value option is elected are reported at fair value with changes in fair value reported in trading revenues. The application of the fair value option does not change the loan’s classification. Loan commitments carried at fair value are recorded in other assets or other liabilities, respectively. Goodwill and other intangible assets Goodwill arises on the acquisition of subsidiaries and equity method investments. It is measured as the excess of the fair value of the consideration transferred, the fair value of any noncontrolling interest in the acquiree and the fair value of any previously held equity interest in the acquired subsidiary, over the net of the acquisition-date fair values of the identifiable assets acquired and the liabilities assumed. Goodwill is not amortized; instead it is tested for impairment annually, or more frequently if events or changes in circumstances indicate that goodwill may be impaired. Goodwill is allocated to the Group’s reporting units for the purposes of the impairment test. Other intangible assets may be acquired individually or as part of a group of assets assumed in a business combination. Other intangible assets include but are not limited to: patents, licenses, copyrights, trademarks, branch networks, mortgage servicing rights, customer base and deposit relationships. Acquired intangible assets are initially measured at the amount of cash disbursed or the fair value of other assets distributed. Other intangible assets that have a finite useful life are amortized over that period. Other intangible assets acquired after January 1, 2002 that are determined to have an indefinite useful life are not amortized; instead they are tested for impairment annually, or more frequently if events or changes in circumstances indicate that the indefinite intangible asset may be impaired. Mortgage servicing rights are included in non-amortizing other intangible assets and are carried at fair value, with changes in fair value recognized through earnings in the period in which they occur. Mortgage servicing rights represent the right to perform specified mortgage servicing activities on behalf of third parties. Mortgage servicing rights are either purchased from third parties or retained upon sale of acquired or originated loans. Income taxes Deferred tax assets and liabilities are recorded for the expected future tax consequences of temporary differences between the carrying amounts of assets and liabilities at the dates of the consolidated balance sheets and their respective tax bases. Deferred tax assets and liabilities are computed using currently enacted tax rates and are recorded in other assets and other liabilities, respectively. Income tax expense or benefit is recorded in income tax expense/(benefit), except to the extent the tax effect relates to transactions recorded directly in total shareholders’ equity. Deferred tax assets are reduced by a valuation allowance, if necessary, to the amount that management believes will more likely th

Summary of significant accounting policies	1 Summary of significant accounting policies The accompanying consolidated financial statements of Credit Suisse AG (the Bank), the direct bank subsidiary of Credit Suisse Group AG (the Group), are prepared in accordance with accounting principles generally accepted in the US (US GAAP) and are stated in Swiss francs (CHF). The financial year for the Bank ends on December 31. Certain reclassifications have been made to the prior year’s consolidated financial statements to conform to the current presentation which had no impact on net income/(loss) or total shareholders’ equity. In preparing the consolidated financial statements, management is required to make estimates and assumptions including, but not limited to, the fair value measurements of certain financial assets and liabilities, the allowance for loan losses, the evaluation of variable interest entities (VIEs), the impairment of assets other than loans, recognition of deferred tax assets, tax uncertainties, pension liabilities and various contingencies. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the dates of the consolidated balance sheets and the reported amounts of revenues and expenses during the reporting period. While management evaluates its estimates and assumptions on an ongoing basis, actual results could differ materially from management’s estimates. Market conditions may increase the risk and complexity of the judgments applied in these estimates. > Refer to “Note 1 – Summary of significant accounting policies” in VI – Consolidated financial statements – Credit Suisse Group for a summary of significant accounting policies, with the exception of the following accounting policies. Pension and other post-retirement benefits Credit Suisse sponsors a Group defined benefit pension plan in Switzerland that covers eligible employees of the Bank domiciled in Switzerland. The Bank also has single-employer defined benefit pension plans and defined contribution pension plans in Switzerland and other countries around the world. For the Bank’s participation in the Group defined benefit pension plan, no retirement benefit obligation is recognized in the consolidated balance sheets of the Bank and defined contribution accounting is applied, as the Bank is not the sponsoring entity of the Group plan. For single-employer defined benefit plans, the Bank uses the projected unit credit actuarial method to determine the present value of its projected benefit obligations (PBO) and the current and past service costs or credits related to its defined benefit and other post-retirement benefit plans. The measurement date used to perform the actuarial valuation is December 31 and is performed by independent qualified actuaries. > Refer to “Pension and other post-retirement benefits” in VI – Consolidated financial statements – Credit Suisse Group – Note 1 – Summary of significant accounting policies for further information. Own shares, own bonds and financial instruments on Group shares The Bank’s shares are wholly owned by Credit Suisse Group AG and are not subject to trading. The Bank may buy and sell Credit Suisse Group AG shares (Group shares) and Group bonds, own bonds and financial instruments on Group shares within its normal trading and market-making activities. In addition, the Bank may hold Group shares to economically hedge commitments arising from employee share-based compensation awards. Group shares are reported as trading assets, unless those shares are held to economically hedge share award obligations. Hedging shares are reported as treasury shares, resulting in a reduction to total shareholder’s equity. Financial instruments on Group shares are recorded as assets or liabilities and carried at fair value. Dividends received on Group shares and unrealized and realized gains and losses on Group shares are recorded according to the classification of the shares as trading assets or treasury shares. Purchases of bonds originally issued by the Bank are recorded as an extinguishment of debt.

Recently issued accounting standards	2 Recently issued accounting standards Recently adopted accounting standards ASC Topic 326 – Financial Instruments – Credit Losses In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-13, “Measurement of Credit Losses on Financial Instruments” (ASU 2016-13), creating ASC Topic 326 – Financial Instruments – Credit Losses. ASU 2016-13 is intended to improve financial reporting by requiring timelier recording of credit losses on financial assets measured at amortized cost basis including, but not limited to loans, net investments in leases and off-balance sheet credit exposures. ASU 2016-13 eliminated the probable initial recognition threshold under the previous incurred loss methodology for recognizing credit losses. Instead, ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date over the remaining contractual life (considering the effect of prepayments) based on historical experience, current conditions and reasonable and supportable forecasts. The Group has incorporated forward-looking information and macroeconomic factors into its credit loss estimates. ASU 2016-13 requires enhanced disclosures to help investors and other financial statement users to better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. In May 2019, the FASB issued ASU 2019-05, “Financial Instruments – Credit Losses” (ASU 2019-05), to provide targeted transition relief upon the adoption of ASU 2016-13. The amendment provided the option to irrevocably elect the fair value option on certain financial assets on transition. As the Group is a US Securities and Exchange Commission (SEC) filer, ASU 2016-13 and its subsequent amendments were effective for annual reporting periods beginning after December 15, 2019, including interim periods within those annual reporting periods. The Group adopted ASU 2016-13 and its subsequent amendments on January 1, 2020, applying the modified retrospective approach, which resulted in a decrease in retained earnings of CHF 132 million, net of tax, with no significant impact on regulatory capital.

Reclassifications are made at amortized cost before allowance of credit loss. The related release of the allowance for credit loss as well as the fair value adjustment between the amortized cost basis and the fair value are reflected in the remeasurement column. 3 Includes the adoption impact on deferred tax assets of CHF 31 million, in addition to the CECL pre-tax remeasurements. ASC Topic 820 – Fair Value Measurement In August 2018, the FASB issued ASU 2018-13, “Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement” (ASU 2018-13), an update to ASC Topic 820 – Fair Value Measurement. The amendments in ASU 2018-13 removed, modified and added certain disclosure requirements in ASC Topic 820, Fair Value Measurement. ASU 2018-13 is effective for annual reporting periods beginning after December 15, 2019 and for the interim periods within those annual reporting periods. Early adoption was permitted, including in an interim period, for any eliminated or modified disclosure requirements. The Group early adopted the amendments for removing disclosures and the amendments for certain modifying disclosures upon the issuance of ASU 2018-13. The Group adopted the remaining amendments on January 1, 2020. As these amendments related only to disclosures, there was no impact from the adoption of ASU 2018-13 on the Group’s financial position, results of operations or cash flows. ASC Topic 848 – Reference Rate Reform In March 2020, the FASB issued ASU 2020-04, “Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (ASU 2020-04), creating ASC Topic 848 - Reference Rate Reform. The amendments in ASU 2020-04 provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments are elective and apply to contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate (LIBOR) or another reference rate expected to be discontinued because of reference rate reform. In January 2021, the FASB issued ASU 2021-01, “Reference Rate Reform, Scope” (ASU 2021-01), which expands the scope of ASC Topic 848 to apply certain optional expedients for contract modifications and hedge accounting provided in ASU 2020-04 to derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified for reference rate reform. The guidance also applies to derivatives that do not reference LIBOR or other reference rates that are expected to be discontinued. The amendments may be applied as of March 12, 2020 through December 31, 2022. The Group elected to apply ASU 2020-04 and retrospectively apply ASU 2021-01 during 2020. These elections did not have a material impact on the Group’s financial position, results of operations and cash flows. Standards to be adopted in future periods ASC Topic 740 – Income Taxes In December 2019, the FASB issued ASU 2019-12, “Simplifying the Accounting for Income Taxes” (ASU 2019-12), an update to ASC Topic 740 – Income Taxes. The amendments in ASU 2019-12 eliminate certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the accounting for basis differences when there are changes in foreign ownership. In addition, ASU 2019-12 includes clarification and simplification of other aspects of the accounting for income taxes. The amendments are effective for annual reporting periods beginning after December 15, 2020 and for the interim periods within those annual reporting periods. Early adoption is permitted, including in an interim period. The adoption of ASU 2019-12 on January 1, 2021 did not have a material impact on the Group’s financial position, results of operations or cash flows.

Business developments	3 Business developments, significant shareholders and subsequent events Business developments Organizational structure and restatement Effective August 1, 2020 the Group created a single, globally integrated Investment Bank division through the combination of its former Global Markets, Investment Banking & Capital Markets and Asia Pacific – Markets businesses to achieve critical scale. The Group also launched a new Sustainability, Research & Investment Solutions (SRI) function at the Executive Board level, underlining the sharpened focus on sustainability. The Group also combined its former Risk Management and Compliance functions into a single integrated Chief Risk and Compliance Officer function to unlock potential global synergies. The Group also revised its allocations for corporate functions and funding costs to align to the new organizational structure. In addition, Global Trading Solutions (GTS) was created within the Investment Bank through the combination of the businesses of International Trading Solutions (ITS) and Asia Pacific Solutions. GTS is a joint venture among the Investment Bank, International Wealth Management, Swiss Universal Bank and Asia Pacific divisions and provides centralized trading and sales services to institutional and private clients. The methodology applied to allocate GTS results across the four divisions reflects the economic contribution from the client base that each division provides to GTS, as well as the historical performance of the constituting businesses, and combines a fixed allocation and an additional split to each division of any GTS outperformance above the fixed allocation. The Group centrally manages its funding activities. As part of the process of implementing the Group’s new divisional structure announced on July 30, 2020, the Group recalibrated its methodology for allocating funding costs across the Group to incorporate net stable funding ratio requirements, certain increased HQLA requirements, as well as funding maturity profile developments. Reflecting these updates, the Group’s financial reporting is now presented as four reporting segments plus the Corporate Center. Prior periods have been restated to conform to the current presentation. These restatements had no impact on the net income/(loss) or the total shareholders’ equity of the Group. Neue Aargauer Bank integration In the fourth quarter of 2020, the Group merged the business of its wholly owned subsidiary, Neue Aargauer Bank AG, with Credit Suisse (Schweiz) AG, in order to establish a single brand in the Canton of Aargau. The merger was effected on November 27, 2020 under simplified requirements of the Swiss Merger Act with retroactive effect as of July 1, 2020. Credit Suisse InvestLab AG Following the completion of the first step of the combination of the Group’s open architecture investment fund platform Credit Suisse InvestLab AG (InvestLab) and Allfunds Group in September 2019, the Group successfully completed the second and final step of the combination in March 2020 with the transfer of related distribution agreements to Allfunds Group. Other revenues in 2020 included CHF 268 million from this second closing, reflected in net revenues of the Swiss Universal Bank, International Wealth Management and Asia Pacific divisions. Credit Suisse Founder Securities Limited In 2020, the Group received approval from the China Securities Regulatory Commission and increased its shareholding in the securities joint venture Credit Suisse Founder Securities Limited to 51% 33.3% York Capital Management In the fourth quarter of 2020, York Capital Management (York) informed its investors of a significant change in strategy. As a result, York will focus on longer duration assets such as private equity, private debt and collateralized loan obligations, while winding down its European hedge funds business and primarily managing internal capital in its multi-strategy fund. York’s Asia Pacific business is expected to be spun off as a new and separate hedge fund in 2021, in which the Group intends to have a continuing interest. As a result of this announcement, the Group recorded an impairment of CHF 414 million to the valuation of its noncontrolling interest that it has owned since 2010, recognized in other revenues. COVID-19 pandemic The COVID-19 pandemic and the consequences for markets and the global economy affected the Group’s financial performance in 2020, including significant impacts on provision for credit losses, as well as on trading revenues and net interest income as a result of foreign exchange movements and a sharp reduction in US dollar interest rates. The Group continues to closely monitor the COVID-19 pandemic and its effects on its operations and businesses. Should current economic conditions persist or continue to deteriorate, the macroeconomic environment may have an adverse effect on these and other aspects of the Group’s business, operations and financial performance, including decreased client activity or demand for its products. Significant shareholders Significant shareholders registered in the share register The following table includes significant shareholders (including nominees) with holdings in Group shares of at least 5% of the voting rights, which were registered in the share register as of December 31, 2020 and 2019, respectively.

Information received from shareholders not registered in the share register In addition to the shareholdings registered in the share register of the Group, the Group has obtained and reported to the SIX Swiss Exchange information from its shareholders in accordance with the notification requirements of the Swiss Federal Act on Financial Market Infrastructures and Market Conduct in Securities and Derivatives Trading. These shareholders may hold their shareholdings in Group shares through a nominee. The following shareholder notifications relate to registered voting rights exceeding 5% of all voting rights, which are subject to disclosure in the notes to the financial statements in accordance with the Swiss Code of Obligations. In a disclosure notification that the Group published on November 9, 2013, the Group was notified that as of November 4, 2013, Harris Associates L.P. held 81.5 million shares, or 5.17% 4.97% In a disclosure notification that the Group published on September 6, 2018, the Group was notified that as of August 24, 2018, Qatar Holding LLC held 133.2 million shares, or 5.21% Subsequent event On March 1, 2021, the boards of the supply chain finance funds managed by certain Group subsidiaries decided to suspend redemptions and subscriptions of those funds to protect the interests of the funds’ investors. On March 4, 2021, the boards decided to terminate those funds and proceed to their liquidation. Those decisions were based on concerns that a substantial part of the funds’ assets was subject to considerable valuation uncertainty. Credit Suisse Asset Management (Schweiz) AG (CSAM) acts as the portfolio manager of these supply chain finance funds. Redemptions and subscriptions of certain other funds managed by CSAM or CSAM subsidiaries that invest in part in these supply chain finance funds have also been suspended. The assets held by the supply chain finance funds, largely consisting of notes backed by existing and future receivables, were originated and structured by Greensill Capital (UK) Limited or one of its affiliates (Greensill Capital). The last published net asset value of the supply chain finance funds in late February was approximately USD 10 billion in the aggregate. Initial redemption payments totaling USD 3.1 billion across the supply chain finance funds were made to their investors beginning on March 8, 2021. The portfolio manager continues to work to liquidate the remaining assets in the four funds as the receivables comprising the funds’ assets mature. Greensill Capital filed for insolvency in the UK on March 8, 2021, and the portfolio manager is working closely with the administrators of Greensill Capital, Grant Thornton, and with other parties to facilitate this process. However, there remains considerable uncertainty regarding the valuation of a significant part of the remaining assets, including the fact that the portfolio manager has been informed that certain of the notes underlying the funds will not be repaid when they fall due, and the amounts that ultimately will be distributed to investors in respect of the funds. Group subsidiaries also have collateralized bridge lending and other direct and indirect exposures to Greensill Capital, including exposures relating to certain fund-linked products. With regard to the outstanding collateralized bridge loan of USD 140 million, USD 50 million was recently repaid by the administrators of Greensill Capital, reducing the outstanding amount of the loan to USD 90 million. The Group continues to analyze these matters, including with the assistance of external counsel and other experts. The Board of Directors has also initiated an investigation of these matters. It has been decided that as of March 10, 2021, three senior CSAM employees will not be performing their roles for the time being. The payout and vesting of variable compensation of a number of senior employees involved in these matters, up to and including Executive Board members, has been suspended as a measure to ensure that the Group can reconsider the variable compensation for 2020 and are able to apply malus or clawback, if appropriate. A number of regulatory investigations and actions have been initiated or are being considered in respect of these matters, including by FINMA, one of which is the agreement to a Pillar 2 buffer with Credit Suisse. Furthermore, certain investors have already threatened litigation and, as this matter develops, Credit Suisse may become subject to litigation, disputes or other actions. The priority for Credit Suisse remains the recovery of funds for CSAM’s investors, and the portfolio manager is working closely with the administrators to facilitate this process. Credit Suisse notes that it is reasonably possible that Credit Suisse will incur a loss in respect of these matters, albeit that given the early stage of this process, it is not yet possible to estimate the size of such a reasonably possible loss. However, the ultimate cost to the Group of resolving these matters may be material to its operating results. Credit Suisse might also suffer reputational harm associated with these matters that might cause client departures or loss of assets under management.

Segment information

Segment information	12 Months Ended
	Dec. 31, 2020
Segment information	4 Segment information The Group is a global financial services company domiciled in Switzerland and serves its clients through three regionally focused divisions: Swiss Universal Bank, International Wealth Management and Asia Pacific. These regional businesses are supported by the Investment Bank division. Beginning in 2019, the Strategic Resolution Unit ceased to exist as a separate division of the Group. The residual portfolio remaining as of December 31, 2018 is now managed in an Asset Resolution Unit and is separately disclosed within our Corporate Center. Effective August 1, 2020 the Group created a single, globally-integrated Investment Bank division through the combination of its former Global Markets, Investment Banking & Capital Markets and Asia Pacific – Markets businesses to achieve critical scale. The Group also revised its allocations for corporate functions and funding costs to align to the new organizational structure. > Refer to “Organizational structure and restatement” in Note 3 – Business developments, significant shareholders and subsequent events – Business developments for further information. The segment information reflects the Group’s reportable segments and the Corporate Center, which are managed and reported on a pre-tax basis, as follows: ■ Swiss Universal Bank ■ International Wealth Management ■ Asia Pacific ■ Investment Bank Corporate Center includes parent company operations such as Group financing, expenses for projects sponsored by the Group and certain expenses and revenues that have not been allocated to the segments. In addition, the Corporate Center includes consolidation and elimination adjustments required to eliminate intercompany revenues and expenses. Revenue sharing and cost allocation Responsibility for each product is allocated to a specific segment, which records all related revenues and expenses. Revenue-sharing and service level agreements govern the compensation received by one segment for generating revenue or providing services on behalf of another. These agreements are negotiated periodically by the relevant segments on a product-by-product basis. The aim of revenue-sharing and service level agreements is to reflect the pricing structure of unrelated third-party transactions. Corporate services and business support in finance, operations, human resources, legal, compliance, risk management and IT are provided by corporate functions, and the related costs are allocated to the segments and Corporate Center based on their requirements and other relevant measures. Funding The Group centrally manages its funding activities. New instruments for funding and capital purposes are primarily issued by Credit Suisse Group AG and are passed on to Credit Suisse AG, the direct bank subsidiary of the Group (the Bank). The Bank lends funds to its operating subsidiaries and affiliates on both a senior and subordinated basis, as needed, the latter typically to meet capital requirements, or as desired by management to capitalize on opportunities. Capital is distributed to the segments considering factors such as regulatory capital requirements, utilized economic capital and the historic and future potential return on capital. Transfer pricing, using market rates, is used to record net revenues and expenses in each of the segments for this capital and funding. The Group’s funds transfer pricing system is designed to allocate funding costs to its businesses in a way that incentivizes their efficient use of funding. The Group’s funds transfer pricing system is an essential tool that allocates to the businesses the short-term and long-term costs of funding their balance sheet usages and off-balance sheet contingencies. The funds transfer pricing framework ensures the full funding costs allocation under normal business conditions, but it is of even greater importance in a stressed capital markets environment where raising funds is more challenging and expensive. Under this framework, the Group’s businesses are also credited to the extent they provide long-term stable funding.

The main components include certain instruments from the following categories: ■ ■ ■ ■ ■ Managing the risks As a result of the Group’s broad involvement in financial products and markets, its trading strategies are correspondingly diverse and exposures are generally spread across a diversified range of risk factors and locations. The Group uses an economic capital limit structure to limit overall risk taking. The level of risk incurred by its divisions is further managed by a variety of factors and specific risk constraints, including consolidated controls over trading exposures. Also, as part of its overall risk management, the Group holds a portfolio of economic hedges. Hedges are impacted by market movements, similar to trading securities, and may result in gains or losses on the hedges which offset losses or gains on the portfolios they were designed to economically hedge. The Group manages its trading risk with regard to both market and credit risk. The Group uses market risk measurement and management methods capable of calculating comparable exposures across its many activities and employs focused tools that can model unique characteristics of certain instruments or portfolios. The principal risk measurement methodology for trading book exposures is value-at-risk. Macroeconomic and specific hedging strategies are in place to manage and mitigate the market and credit risk in the trading book.

Revenue from contracts with cus

Revenue from contracts with customers	12 Months Ended
	Dec. 31, 2020
Revenue from Contract with Customer [Text Block]	14 Revenue from contracts with customers Revenue is measured based on the consideration specified in a contract with a customer, and excludes any amounts collected on behalf of third parties. Taxes assessed by a governmental authority that are collected by the Group from a customer and both imposed on and concurrent with a specific revenue-producing transaction are excluded from revenue. The Group recognizes revenue when it satisfies a contractual performance obligation. Variable consideration is only included in the transaction price once it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the amount of variable consideration is subsequently resolved. Generally no significant judgement is required with respect to recording variable consideration. If a fee is a fixed percentage of a variable account value at contract inception, recognition of the fee revenue is constrained as the contractual consideration is highly susceptible to change due to factors outside of the Group’s influence. However, at each performance measurement period end (e.g., end-of-day, end-of-month, end-of-quarter), recognition of the cumulative amount of the consideration to which the Group is entitled is no longer constrained because it is calculated based on a known account value and the fee revenue is no longer variable. Nature of services The following is a description of the principal activities from which the Group generates its revenues from contracts with customers. The performance obligations are typically satisfied as the services in the contract are rendered. The contract terms are generally such that they do not result in any contract assets. The contracts generally do not include a significant financing component or obligations for refunds or other similar obligations. Any variable consideration included in the transaction price is only recognized when the uncertainty of the amount is resolved and it is probable that a significant reversal of cumulative revenue recognized will not occur. Credit Suisse’s wealth management businesses provide investment services and solutions for clients, including asset management, investment advisory and investment management, wealth planning, and origination and structuring of sophisticated financing transactions. The Group receives for these services investment advisory and investment management fees which are generally reflected in the line item “Investment and portfolio management” in the table “Contracts with customers and disaggregation of revenues” below. Generally, the fee for the service provided is recognized over the period of time the service is provided. The wealth management businesses also provide comprehensive advisory services and tailored investment and financing solutions to private, corporate and institutional clients. The nature of the services range from investment and wealth management activities, which are services rendered over a period of time according to the contract with the customer, to more transaction-specific services such as brokerage and sales and trading services and the offer of client-tailored financing products. The services are provided as requested by Credit Suisse’s clients, and the fee for the service requested is recognized once the service is provided. The Group’s asset management businesses offer investment solutions and services globally to a broad range of clients, including pension funds, governments, foundations and endowments, corporations and individuals. Fund managers typically enter into a variety of contracts to provide investment management and other services. A fund manager may satisfy its performance obligation independently or may engage a third party to satisfy some or all of a performance obligation on the fund manager’s behalf. Although the fund manager may have engaged a third party to provide inputs to the overall investment management services, the contractual obligation to provide investment management services to a customer remains the primary responsibility of the fund manager. As such, the fund manager is acting as a principal in the transaction. As a fund manager, the Group typically receives base management fees and may additionally receive performance-based management fees which are both recognized as “Investment and portfolio management” revenues in the table “Contracts with customers and disaggregation of revenues” below. Base management fees are generally calculated based on the net asset value (NAV) of the customer’s investment, which can change during the performance period. Performance-based management fees are variable consideration received by the Group depending on the financial performance of the underlying fund. As both the base management fees and performance-based management fees are variable, the Group recognizes the fees once it is probable that a significant reversal of the revenue recognized will not occur and when the uncertainty of the amount is resolved. The estimate of these variable fees is constrained until the end of the performance measurement period. Generally, the uncertainty is resolved at the end of the performance measurement period and therefore no significant judgement is necessary when recording variable consideration. Under a clawback obligation provision, a fund manager may be required to return certain distributions received from a fund if a specific performance threshold, i.e., benchmark, is not achieved at the end of the lifetime of the fund. The contractual clawback obligation is an additional factor of uncertainty which is considered in the constraint assessment. If the performance-based management fee is earned but the clawback provision has not lapsed, the clawback obligation is accounted for as a refund liability. The Group’s capital markets businesses underwrite and sell securities on behalf of customers. Typically, the fees in these businesses are recognized at a single point in time once the transaction is complete, i.e., when the securities have been placed with investors, and recognized as underwriting revenue. All expenses incurred in satisfying the performance obligation are deferred and recognized once the transaction is complete. Generally Credit Suisse and other banks form a syndicate group to underwrite and place the securities for a customer. The Group may act as the lead or a participating member in the syndicate group. Each member of the syndicate group, including the lead and participating underwriters, is acting as principal for their proportionate share of the syndication. As a result, the individual underwriters reflect their proportionate share of underwriting revenue and underwriting costs on a gross basis. The Group also offers brokerage services in its investment banking businesses, including global securities sales, trading and execution, prime brokerage and investment research. For the services provided, such as the execution of client trades in securities or derivatives, the Group typically earns a brokerage commission when the trade is executed. The Group generally acts as an agent when buying or selling exchange-traded cash securities, exchange-traded derivatives or centrally cleared OTC derivatives on behalf of clients. Credit Suisse’s investment banking businesses provide services that include advisory services to clients in connection with corporate finance activities. The term “advisory” includes any type of service the Group provides in an advisory capacity. For these types of services, the Group typically receives a non-refundable retainer fee and/or a success fee which usually represents a percentage of the transaction proceeds if and when the corporate finance activity is completed. Additionally, the contract may contain a milestone fee such as an “announcement fee” that is payable upon the public announcement of the corporate finance activity. Typically the fees in the investment banking business are recognized at a specific point in time once it is determined that the performance obligation related to the transaction has been completed. A contract liability will be recorded if the Group receives a payment such as a retainer fee or announcement fee for an advisory service prior to satisfying the performance obligation. Advisory fees are recognized ratably over time in scenarios where the contracted service of the Group is to act as an advisor over a specified period not related to or dependent on the successful completion of a transaction. Revenues recognized from these services are reflected in the line item “Other Services” in the table below.

Capitalized costs The Group has not incurred costs to obtain a contract nor costs to fulfill a contract that are eligible for capitalization. Remaining performance obligations ASC Topic 606’s practical expedient allows the Group to exclude from its remaining performance obligations disclosure any performance obligations which are part of a contract with an original expected duration of one year or less. Additionally any variable consideration, for which it is probable that a significant reversal in the amount of cumulative revenue recognized will occur when the uncertainty associated with the variable consideration is subsequently resolved, is not subject to the remaining performance obligations disclosure because such variable consideration is not included in the transaction price (e.g., investment management fees). Upon review, the Group determined that no material remaining performance obligations are in scope of the remaining performance obligations disclosure.

These accrued interest balances are reported in other assets. 3 Includes endangered interest of CHF 88 million on non-accrual loans which are reported as part of the loans' amortized cost balance. Allowance for credit losses Estimating expected credit losses – overview The following key elements and processes of estimating expected credit losses apply to the Group’s major classes of financial assets held at amortized cost. Expected credit losses on non-impaired credit exposures Expected credit loss models for non-impaired credit exposures have three main inputs: (i) probability of default (PD), (ii) loss given default (LGD) and (iii) exposure at default (EAD). These parameters are derived from internally developed statistical models which are based on historical data and leverage regulatory models under the advanced internal rating-based approach. Expected credit loss models use forward-looking information to derive point-in-time estimates of forward-looking term structures. PD estimates are based on statistical rating models and tailored to various categories of counterparties and exposures. These statistical rating models are based on internally and externally compiled data comprising both quantitative and qualitative factors. A migration of a counterparty or exposure between rating classes generally leads to a change in the estimate of the associated PD. Lifetime PDs are estimated considering the expected macroeconomic environment and the contractual maturities of exposures, adjusted for estimated prepayment rates where applicable. LGD estimates the size of the expected loss that may arise on a credit exposure in the event of a default. The Group estimates LGD based on the history of recovery rates of claims against defaulted counterparties, considering, as appropriate, factors such as differences in product structure, collateral type, seniority of the claim, counterparty industry and recovery costs of any collateral that is integral to the financial asset. Certain LGD values are also calibrated to reflect the expected macroeconomic environment. EAD represents the expected amount of credit exposure in the event of a default. It reflects the current drawn exposure with a counterparty and an expectation regarding the future evolution of the credit exposure under the contract or facility, including amortization and prepayments. The EAD of a financial asset is the gross carrying amount at default, which is modeled based on historical data by applying a term structure and considering portfolio-specific factors such as the drawn amount as of the reporting date, the facility limit, amortization schedules, financial collateral and product type. For certain financial assets, the Group determines EAD by modeling the range of possible exposure outcomes at various points in time using scenario and statistical techniques. Where a relationship to macroeconomic indicators is statistically sound and in line with economic expectations, the parameters are modeled accordingly, incorporating the Group’s forward looking forecasts and applying regional segmentations where appropriate. The Group’s macroeconomic and market variable forecasts for the CECL scenarios cover a five-year time horizon. For periods beyond that reasonable and supportable forecast period, the Group immediately reverts to average economic environment variables as model input factors. Alternative qualitative estimation approaches are used for certain products. For lombard loans (including share-backed loans), the PD/LGD approach used does not consider the Group’s forward looking forecasts as these are not meaningful for the estimate of expected credit losses in light of the short time-frame considered for closing out positions under daily margining arrangements. For international private residential mortgages and securitizations, the Group applies qualitative approaches where credit specialists follow a structured process and use their expertise and judgment to determine the CECL amounts. The Group measures expected credit losses considering the risk of default over the maximum contractual period (including any borrower’s extension options) during which it is exposed to credit risk, even if the Group considers a longer period for risk management purposes. The maximum contractual period extends to the date at which the Group has the right to require repayment of an advance or terminate an irrevocable loan commitment or a credit guarantee. Expected credit losses on impaired credit exposures Expected credit losses for individually impaired credit exposures are measured by performing an in-depth review and analysis of these exposures, considering factors such as recovery and exit options as well as collateral and the risk profile of the borrower. The individual measurement of expected credit losses for impaired financial assets also considers reasonable and supportable forward-looking information that is relevant to the individual counterparty (idiosyncratic information) and reflective of the macroeconomic environment that the borrower is exposed to, apart from any historical loss information and current conditions. If there are different scenarios relevant for the individual expected credit loss measurement, they are considered on a probability-weighted basis. The related allowance for credit losses is revalued by Credit Risk, at least annually or more frequently, depending on the risk profile of the borrower or credit-relevant events. For credit-impaired financial assets, the expected credit losses are measured using the present value of estimated future cash flows (unless a practical expedient for collateral-dependent financial assets is applied) and the impaired credit exposures and related allowance are revalued to reflect the passage of time. For all classes of financial assets, the trigger to detect an impaired credit exposure is non-payment of interest, principal amounts or other contractual payment obligations, or when, for example, the Group may become aware of specific adverse information relating to a counterparty’s ability to meet its contractual obligations, despite the current repayment status of its particular credit facility. For credit exposures where repayment is dependent on collateral, a decrease in collateral values can be an additional trigger to detect an impairment. Additional procedures may apply to specific classes of financial assets as described further below. Troubled debt restructurings, also referred to as restructured loans, are considered impaired credit exposures in line with the Group’s policies and subject to individual assessment and provisioning for expected credit losses by the Group’s recovery functions. Restructured loans that defaulted again within 12 months from the last restructuring remain impaired or are impaired if they were considered non-impaired at the time of the subsequent default. Macroeconomic scenarios The estimation and application of forward-looking information requires quantitative analysis and significant expert judgment. The Group’s estimation of expected credit losses is based on a discounted probability-weighted estimate that considers three future macroeconomic scenarios: a baseline scenario, an upside scenario and a downside scenario. The baseline scenario represents the most likely outcome. The two other scenarios represent more optimistic and more pessimistic outcomes with the downside scenario being more severe than the upside scenario. The scenarios are probability-weighted according to the Group’s best estimate of their relative likelihood based on historical frequency, an assessment of the current business and credit cycles as well as the macroeconomic factor (MEF) trends. The scenario design team within the Group’s Enterprise Risk Management (ERM) function determines the MEFs and market projections that are relevant for the Group’s three scenarios across the global credit portfolio. The scenario design team formulates the baseline scenario projections used for the CECL calculation from the Group’s global chief investment office in-house economic research forecasts and, where deemed appropriate, from external sources such as the Bloomberg consensus of economist forecasts (covering the views of other investment banks and external economic consultancies), forecasts from nonpartisan think tanks, major central banks and multilateral institutions, such as the International Monetary Fund (IMF), the Organisation for Economic Co-operation and Development (OECD) and the World Bank. For factors where no in-house or credible external forecasts are available, an internal model is used to calibrate the baseline scenario projections. The downside and upside scenarios are derived from these baseline scenario projections. These three scenario projections are subject to a review and challenge process and any feedback from this process is incorporated into the scenario projections by the ERM scenario design team. The CECL scenario design working group is the governance forum. The working group performs an additional review and challenge and subsequently recommends approval of the MEFs and related market projections as well as the occurrence probability weights that are allocated to the baseline, downside and upside scenarios. MEFs and related market projections as well as the scenario occurrence probability weights used for the calculation of CECL are approved by the Senior Management Approval Committee. Current-period estimate of expected credit losses The key MEFs used in each of the macroeconomic scenarios for the calculation of the expected credit losses include, but are not limited to, GDP and unemployment rates. These MEFs have been selected based on the portfolios that are most material to the estimation of CECL from a longer term perspective. As of December 31, 2020, the forecast macroeconomic scenarios were weighted 50% 40% 10% 0.1% 5.4% 0.8% 4.5% 0.3% 7.8% 2.8% 3.9% 0.5% 5.2% 2.0% 5.1% 2.4% 8.6% 2.9% 5.9% For extreme and statistically rare events which cannot be adequately reflected in CECL models, such as the effects of the COVID-19 pandemic on the global economy, the event becomes the baseline scenario. In the current environment, to address circumstances where in management’s judgment the CECL model outputs are overly sensitive to the effect of economic inputs that lie significantly outside of their historical range, model overlays are applied. These overlays are based on expert judgment and are applied in response to these exceptional circumstances to consider historical stressed losses and industry and counterparty credit level reviews. Overlays have also been used to capture judgment on the economic uncertainty from the lockdowns and other actions directed towards managing the pandemic. As a result of these overlays, provisions for credit losses are not primarily derived from MEF projections. Interest income attributable to passage of time For financial assets held at amortized cost for which the Group measures expected credit losses based on the discounted cash flow methodology the entire change in present value is reported in provision for credit losses. Methodology changes The probability of default model for commodity trade finance exposures was adjusted during the reporting period to reflect the latest model development analysis and expert feedback. This change has been supported by backtesting results. The impact from this model change has been reflected in the table “Allowance for credit losses – loans held at amortized cost”. Loans held at amortized cost The Group’s loan portfolio is classified into two portfolio segments, consumer loans and corporate & institutional loans. The main risk characteristics are described by individual class of financing receivable for each of these portfolio segments: Consumer loans: ■ ■ ■ Corporate & institutional loans: ■ ■ ■ ■ Expected credit losses on impaired loans In addition to the triggers described further above, loans managed on the Swiss platform are reviewed depending on event-driven developments. All corporate and institutional loans are reviewed at least annually based on the borrower’s financial statements and any indications of difficulties they may experience. Loans that are not impaired, but which are of special concern due to changes in covenants, downgrades, negative financial news and other adverse developments, are either transferred to recovery management or included on a watch list. All loans on the watch list are reviewed at least quarterly to determine whether they should be released, remain on the watch list or be moved to recovery management. For loans in recovery management from the Swiss platform, larger positions are reviewed on a quarterly basis for any event-driven changes. Otherwise, these loans are reviewed at least annually. All loans in recovery management on international platforms are reviewed on at least a monthly basis.

The Group determined in the first quarter of 2020 that a goodwill triggering event occurred for its former Investment Banking & Capital Markets reporting unit. Based on its goodwill impairment analysis performed, the Group concluded that the estimated fair value for all of the reporting units with goodwill exceeded their related carrying values and no impairments were necessary as of March 31, 2020. The Group also determined in the second quarter of 2020 that a goodwill triggering event occurred for its former Asia Pacific – Markets, Global Markets and Investment Banking & Capital Markets reporting units. Goodwill has to be tested for impairment before and immediately after a reorganization of reporting units. Based on this goodwill impairment analysis, the Group concluded that there would be no impairment necessary for its Global Markets, Investment Banking & Capital Markets and Asia Pacific – Markets reporting units under the prior reporting structure as the estimated fair value of these reporting units exceeded their related carrying values by 11% 13% 6% The approach for determining the carrying value and estimating the fair values of the reporting units was applied consistently for both the prior reporting structure and the new reporting structure. The carrying value of each reporting unit for the purpose of the goodwill impairment test is determined by considering the reporting units’ risk-weighted assets usage, leverage ratio exposure, deferred tax assets, goodwill, intangible assets and other common equity tier 1 (CET1) capital relevant adjustments. Any residual equity, after considering the total of these elements, is allocated to the reporting units on a pro-rata basis. In estimating the fair value of its reporting units, the Group applied a combination of the market approach and the income approach. Under the market approach, consideration was given to price to projected earnings multiples or price to book value multiples for similarly traded companies and prices paid in recent transactions that have occurred in its industry or in related industries. Under the income approach, a discount rate was applied that reflects the risk and uncertainty related to the reporting unit’s projected cash flows, which were determined from the Group’s financial plan. In determining the estimated fair value, the Group relied upon its latest five-year financial plan which included significant management assumptions and estimates based on its view of current and future economic conditions and regulatory changes. The Group engaged the services of an independent valuation specialist to assist in the valuation of the International Wealth Management – Asset Management, Asia Pacific and the Investment Bank reporting units as of December 31, 2020. The valuations were performed using a combination of the market approach and income approach. The results of the impairment evaluation of each reporting unit’s goodwill would be significantly impacted by adverse changes in the underlying parameters used in the valuation process. If actual outcomes or the future outlook adversely differ from management’s best estimates of the key economic assumptions and associated cash flows applied in the valuation of the reporting unit, the Group could potentially incur material impairment charges in the future. As a result of acquisitions, the Group has recorded goodwill as an asset in its consolidated balance sheets, the most significant component of which arose from the acquisition of Donaldson, Lufkin & Jenrette Inc. in 2000.

Lessee arrangements The Group primarily enters into operating leases. When a real estate lease has both lease and non-lease components, the Group allocates the consideration in the contract based on the relative standalone selling price. For all leases other than real estate leases, the Group does not separate lease and non-lease components. The Group’s finance leases are not material. The Group has entered into leases for real estate, equipment and vehicles. Certain equipment and real estate have subsequently been subleased. Sublease income is recognized in other revenues.

If specific criteria are met, the asset is derecognized from the balance sheet and an operating lease is recognized. During 2020, the Group entered into one sale-leaseback transaction, with a lease term of one year. During 2019, the Group entered into 4 sale-leaseback transactions, with lease terms ranging from 5 to 10 years.

The Group enters into leases with fixed or variable lease payments, or with lease payments that depend on an index or a referenced rate which are included in the net investment in the lease at lease commencement, as such payments are considered unavoidable. Other variable lease payments, as well as subsequent changes in an index or referenced rate, are excluded from the net investment in the lease. Lease payments are recorded when due and payable by the lessee.

The Group may enter into vehicle leases as a lessor with members of the Board of Directors or the Executive Board. The terms of such leases with members of the Board of Directors are similar to those with third parties and the terms of such leases with members of the Executive Board reflect standard employee conditions.

Long-term debt includes both Swiss franc and foreign exchange denominated fixed and variable rate bonds. The interest rate ranges presented in the table below are based on the contractual terms of the Group’s vanilla debt. Interest rate ranges for future coupon payments on structured products for which fair value has been elected are not included in the table below as these coupons are dependent upon the embedded derivative and prevailing market conditions at the time each coupon is paid. In addition, the effects of derivatives used for hedging are not included in the interest rate ranges on the associated debt. Group-internal funding related to loss-absorbing instruments has been aligned to international standards for internal total loss-absorbing capacity (TLAC) instruments and to the new article 126b of the Swiss Capital Adequacy Ordinance, effective January 1, 2020. Due to this alignment, the bail-in debt instruments issued by Credit Suisse AG to Credit Suisse Group Funding (Guernsey) Limited, a non-consolidated funding entity, have been permanently subordinated in 2019. Effective November 3, 2020, Credit Suisse Group AG and Credit Suisse Group Funding (Guernsey) Limited exercised the voluntary issuer substitution clause included in the terms of senior unsecured notes issued by Credit Suisse Group Funding (Guernsey) Limited with a maturity date post December 31, 2022. As a result of the substitution, Credit Suisse Group AG succeeded to, and was substituted for, and became bound by every obligation of, Credit Suisse Group Funding (Guernsey) Limited as principal obligor under these notes, which qualify as TLAC debt instruments. In addition, the related subordinated internal TLAC notes issued by Credit Suisse AG and held by Credit Suisse Group Funding (Guernsey) Limited have been transferred to Credit Suisse Group AG. This resulted in a decrease in subordinated long-term debt and a respective increase in senior long-term debt.

Offsetting of financial assets

Offsetting of financial assets and financial liabilities	12 Months Ended
	Dec. 31, 2020
Offsetting of financial assets and financial liabilities	28 Offsetting of financial assets and financial liabilities The disclosures set out in the tables below include derivatives, reverse repurchase and repurchase agreements, and securities lending and borrowing transactions that: ■ ■ Similar agreements include derivative clearing agreements, global master repurchase agreements and global master securities lending agreements. Derivatives The Group transacts bilateral OTC derivatives (OTC derivatives) mainly under International Swaps and Derivatives Association (ISDA) Master Agreements and Swiss Master Agreements for OTC derivative instruments. These agreements provide for the net settlement of all transactions under the agreement through a single payment in the event of default or termination under the agreement. They allow the Group to offset balances from derivative assets and liabilities as well as the receivables and payables to related cash collateral transacted with the same counterparty. Collateral for OTC derivatives is received and provided in the form of cash and marketable securities. Such collateral may be subject to the standard industry terms of an ISDA Credit Support Annex. The terms of an ISDA Credit Support Annex provide that securities received or provided as collateral may be pledged or sold during the term of the transactions and must be returned upon maturity of the transaction. These terms also give each counterparty the right to terminate the related transactions upon the other counterparty’s failure to post collateral. Financial collateral received or pledged for OTC derivatives may also be subject to collateral agreements which restrict the use of financial collateral. For derivatives transacted with exchanges (exchange-traded derivatives) and central clearing counterparties (OTC-cleared derivatives), positive and negative replacement values (PRV/NRV) and related cash collateral may be offset if the terms of the rules and regulations governing these exchanges and central clearing counterparties permit such netting and offset. Where no such agreements or terms exist, fair values are recorded on a gross basis. Exchange-traded derivatives or OTC-cleared derivatives, which are fully margined and for which the daily margin payments constitute settlement of the outstanding exposure, are not included in the offsetting disclosures because they are not subject to offsetting due to the daily settlement. The daily margin payments, which are not settled until the next settlement cycle is conducted, are presented in brokerage receivables or brokerage payables. The notional amount for these daily settled derivatives is included in the fair value of derivative instruments table in “Note 33 – Derivatives and hedging activities”. Under US GAAP, the Group elected to account for substantially all financial instruments with an embedded derivative that is not considered clearly and closely related to the host contract at fair value. There is an exception for certain bifurcatable hybrid debt instruments which the Group did not elect to account for at fair value. However, these bifurcated embedded derivatives are generally not subject to enforceable master netting agreements and are not recorded as derivative instruments under trading assets and liabilities or other assets and other liabilities. Information on bifurcated embedded derivatives has therefore not been included in the offsetting disclosures. The following table presents the gross amount of derivatives subject to enforceable master netting agreements by contract and transaction type, the amount of offsetting, the amount of derivatives not subject to enforceable master netting agreements and the net amount presented in the consolidated balance sheets.

Reverse repurchase and repurchase agreements and securities lending and borrowing transactions Reverse repurchase and repurchase agreements are generally covered by master repurchase agreements. In certain situations, for example, in the event of default, all contracts under the agreements are terminated and are settled net in one single payment. Master repurchase agreements also include payment or settlement netting provisions in the normal course of business that state that all amounts in the same currency payable by each party to the other under any transaction or otherwise under the master repurchase agreement on the same date shall be set off. As permitted by US GAAP the Group has elected to net transactions under such agreements in the consolidated balance sheet when specific conditions are met. Transactions are netted if, among other conditions, they are executed with the same counterparty, have the same explicit settlement date specified at the inception of the transactions, are settled through the same securities transfer system and are subject to the same enforceable master netting agreement. The amounts offset are measured on the same basis as the underlying transaction (i.e., on an accrual basis or fair value basis). Securities lending and borrowing transactions are generally executed under master securities lending agreements with netting terms similar to ISDA Master Agreements. In certain situations, for example in the event of default, all contracts under the agreement are terminated and are settled net in one single payment. Transactions under these agreements are netted in the consolidated balance sheets if they meet the same right of offset criteria as for reverse repurchase and repurchase agreements. In general, most securities lending and borrowing transactions do not meet the criterion of having the same settlement date specified at inception of the transaction, and therefore they are not eligible for netting in the consolidated balance sheets. However, securities lending and borrowing transactions with explicit maturity dates may be eligible for netting in the consolidated balance sheets. Reverse repurchase and repurchase agreements are collateralized principally by government securities, money market instruments and corporate bonds and have terms ranging from overnight to a longer or unspecified period of time. In the event of counterparty default, the reverse repurchase agreement or securities lending agreement provides the Group with the right to liquidate the collateral held. As is the case in the Group’s normal course of business, a significant portion of the collateral received that may be sold or repledged was sold or repledged as of December 31, 2020 and December 31, 2019. In certain circumstances, financial collateral received may be restricted during the term of the agreement (e.g., in tri-party arrangements).

Following the publication of the 2019 financial statements, Credit Suisse continued its analysis of the final regulations, resulting in a revision to the technical application of the prior BEAT estimate. This new information was not available or reasonably knowable at the time of the publication of the 2019 financial statements and resulted in a change of accounting estimate reflected in 2020. 2019 Foreign tax rate differential Other non-deductible expenses Lower taxed income Changes in deferred tax valuation allowances Other 2018 Foreign tax rate differential Other non-deductible expenses Lower taxed income Changes in deferred tax valuation allowances Other As of December 31, 2020, the Group had accumulated undistributed earnings from foreign subsidiaries of CHF 20.1 billion compared to CHF 17.8 billion as of December 31, 2019. The increase compared to the end of 2019 reflected a reserve transfer in one of the Group’s entities. No deferred tax liability was recorded in respect of those amounts as these earnings are considered indefinitely reinvested. It is not practicable to estimate the amount of unrecognized deferred tax liabilities for these undistributed foreign earnings.

These decreases were partially offset by the tax impacts directly recorded in equity and OCI of CHF 38 million, mainly related to own credit movements. In 2019, the US and Switzerland contributed the majority of the net deferred tax assets, CHF 3,855 million, net of a valuation allowance of CHF 606 million. In 2020, following the deferred tax asset re-assessment in Switzerland, the US contributed the majority of the net deferred tax assets, CHF 3,040 million. No valuation allowance was required on the US deferred tax assets as of the end of 2020. Due to uncertainty concerning its ability to generate the necessary amount and mix of taxable income in future periods, the Group recorded a valuation allowance against gross deferred tax assets in the amount of CHF 4.5 billion as of December 31, 2020 compared to CHF 4.1 billion as of December 31, 2019.

This evaluation was dependent on management estimates and assumptions in developing the expected future results, which were based on a strategic business planning process influenced by current economic conditions and assumptions of future economic conditions that are subject to change. This evaluation took into account both positive and negative evidence related to expected future taxable income and also considered stress scenarios. This evaluation has indicated the expected future results that are likely to be earned in jurisdictions where the Group has significant gross deferred tax assets, primarily in the US, Switzerland and the UK. The Group then compared those expected future results with the applicable law governing the utilization of deferred tax assets. US tax law allowed for a 20-year carry-forward period for existing NOLs as of the end of 2017, federal NOLs generated in tax years 2018, 2019 and 2020 can be carried back for five years and any new NOLs will have an unlimited carry-forward period. UK tax law allows for an unlimited carry-forward period for NOLs. Based on the expected future results in the Bank parent company and given that Swiss tax law allows for a seven-year carry-forward period for NOLs, a valuation allowance was recorded on the deferred tax assets of this entity. Tax benefits associated with share-based compensation in 2020 2019 2018 Tax benefits (CHF million) Tax benefits recorded in the consolidated statements of operations 1 264 263 242 1 Calculated at the statutory tax rate before valuation allowance considerations. > Refer to “Note 30 – Employee deferred compensation” for further information on share-based compensation. If, upon settlement of share-based compensation, the tax deduction exceeds the cumulative compensation cost that the Group has recognized in the consolidated financial statements, the utilized tax benefit associated with any excess deduction is considered a “windfall” and recognized in the consolidated statements of operations and reflected as an operating cash inflow in the consolidated statements of cash flows. If, upon settlement, the tax deduction is lower than the cumulative compensation cost that the Group has recognized in the consolidated financial statements, the tax charge associated with the lower deduction is considered a “shortfall”. Tax charges arising on shortfalls are recognized in the consolidated statements of operations. Uncertain tax positions US GAAP requires a two-step process in evaluating uncertain income tax positions. In the first step, an enterprise determines whether it is more likely than not that an income tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Income tax positions meeting the more-likely-than-not recognition threshold are then measured to determine the amount of benefit eligible for recognition in the consolidated financial statements. Each income tax position is measured at the largest amount of tax benefit that is more likely than not to be realized upon ultimate settlement.

The Group is currently subject to ongoing tax audits, inquiries and litigation with the tax authorities in a number of jurisdictions, including Brazil, the Netherlands, the US, the UK and Switzerland. Although the timing of completion is uncertain, it is reasonably possible that some of these will be resolved within 12 months of the reporting date. It is reasonably possible that there will be a decrease of between zero and CHF 40 million in unrecognized tax benefits within 12 months of the reporting date.

Following the publication of the 2019 financial statements, Credit Suisse continued its analysis of the final regulations, resulting in a revision to the technical application of the prior BEAT estimate. This new information was not available or reasonably knowable at the time of the publication of the 2019 financial statements and resulted in a change of accounting estimate reflected in 2020. 2019 Foreign tax rate differential Other non-deductible expenses Lower taxed income Changes in deferred tax valuation allowances Other 2018 Foreign tax rate differential Other non-deductible expenses Lower taxed income Changes in deferred tax valuation allowances Other As of December 31, 2020, the Bank had accumulated undistributed earnings from foreign subsidiaries of CHF 19.6 billion compared to CHF 17.2 billion as of December 31, 2019. The increase compared to the end of 2019 reflected a reserve transfer in one of the Bank’s entities. No deferred tax liability was recorded in respect of those amounts as these earnings are considered indefinitely reinvested. It is not practicable to estimate the amount of unrecognized deferred tax liabilities for these undistributed foreign earnings.

In 2019, the US and Switzerland contributed the majority of the net deferred tax assets, CHF 3,855 million, net of a valuation allowance of CHF 606 million. In 2020, following the deferred tax assets re-assessment in Switzerland, the US contributed the majority of the net deferred tax assets, CHF 3,040 million. No valuation allowance was required on the US deferred tax assets as of the end of 2020. Due to uncertainty concerning its ability to generate the necessary amount and mix of taxable income in future periods, the Bank recorded a valuation allowance against gross deferred tax assets in the amount of CHF 4.3 billion as of December 31, 2020, compared to CHF 4.1 billion as of December 31, 2019.

Employee deferred compensation

Employee deferred compensation	12 Months Ended
	Dec. 31, 2020
Employee deferred compensation	30 Employee deferred compensation Payment of deferred compensation to employees is determined by the nature of the business, role, location and performance of the employee. Unless there is a contractual obligation, granting deferred compensation is solely at the discretion of the Compensation Committee and senior management. Special deferred compensation granted as part of a contractual obligation is typically used to compensate new senior employees for forfeited awards from previous employers upon joining the Group. It is the Group’s policy not to make multi-year guarantees. Compensation expense recognized in the consolidated statement of operations for share-based and other awards that were granted as deferred compensation is recognized in accordance with the specific terms and conditions of each respective award and is primarily recognized over the future requisite service and vesting period, which is determined by the plan, retirement eligibility of employees and certain other terms. All deferred compensation plans are subject to restrictive covenants, which generally include non-compete and non-solicit provisions. Compensation expense for share-based and other awards that were granted as deferred compensation also includes the current estimated outcome of applicable performance criteria, estimated future forfeitures and mark-to-market adjustments for certain cash awards that are still outstanding. The following tables show the compensation expense for deferred compensation awards granted in 2020 and prior years that was recognized in the consolidated statements of operations during 2020, 2019 and 2018, the total shares delivered, the estimated unrecognized compensation expense for deferred compensation awards granted in 2020 and prior years outstanding as of December 31, 2020 and the remaining requisite service period over which the estimated unrecognized compensation expense will be recognized. The estimated unrecognized compensation expense was based on the fair value of each award on the grant date and included the current estimated outcome of relevant performance criteria and estimated future forfeitures but no estimate for future mark-to-market adjustments. The recognition of compensation expense for the deferred compensation awards granted in February 2021 began in 2021 and thus had no impact on the 2020 consolidated financial statements. Deferred compensation awards for 2020 In February 2021, the Group granted share awards, performance share awards and Contingent Capital Awards (CCA) as deferred compensation. Deferred compensation was awarded to employees with total compensation of CHF/USD 250,000 or the local currency equivalent or higher.

Share awards Share awards granted in February 2021 are similar to those granted in February 2020. Each share award granted entitles the holder of the award to receive one Group share, subject to service conditions. Share awards vest over three years with one third of the share awards vesting on each of the three anniversaries of the grant date (ratable vesting), with the exception of awards granted to individuals classified as risk managers or senior managers under the UK PRA Remuneration Code or similar regulations in other jurisdictions. Share awards granted to risk managers vest over five years with one fifth of the award vesting on each of the five anniversaries of the grant date, while share awards granted to senior managers vest over five years commencing on the third anniversary of the grant date, with one fifth of the award vesting on each of the third to seventh anniversaries of the grant date. Share awards are expensed over the service period of the awards. The value of the share awards is solely dependent on the Group share price at the time of delivery. The Group’s share awards include other awards, such as blocked shares and special awards, which may be granted to new employees. Other share awards entitle the holder to receive one Group share and are generally subject to continued employment with the Group, contain restrictive covenants and cancellation provisions and generally vest between zero and five years. On February 19, 2021, the Group granted 44.6 million share awards with a total value of CHF 592 million. The number of share awards granted to employees was generally determined by dividing the deferred component of variable compensation being granted as share awards by the average price of a Group share over the ten consecutive trading days which ended on March 4, 2021. The fair value of each share award was CHF 12.59, the Group share price on the grant date. The majority of share awards granted include the right to receive dividend equivalents on vested shares. The estimated unrecognized compensation expense of CHF 538 million was determined based on the fair value of the awards on the grant date, includes the current estimated future forfeitures and will be recognized over the vesting period, subject to early retirement rules. Share awards granted for previous years For compensation year 2020 2019 2018 Shares awarded (million) 44.6 57.9 55.6 Value of shares awarded (CHF million) 592 626 638 Fair value of each share awarded (CHF) 1 12.59 10.81 11.75 1 Based on the Group’s share price on the grant date. In order to comply with Capital Requirements Directive IV requirements, employees who hold key roles in respect of certain Group subsidiaries receive shares that are subject to transfer restrictions for 50% of the amount that would have been paid to them in cash. These shares are vested at the time of grant but remain blocked, that is, subject to transfer restrictions, for six months to one year from the date of grant, depending on the location. On February 19, 2021, the Group granted 2.6 million blocked shares with a total value of CHF 35 million that vested immediately upon grant, have no future service requirements and were attributed to services performed in 2020.

Performance share awards are similar to share awards, except that the full balance of outstanding performance share awards, including those awarded in prior years, are subject to performance-based malus provisions. Performance share awards are subject to a negative adjustment in the event of a divisional loss by the division in which the employees worked as of December 31, 2020, or a negative ROE of the Group, whichever results in a larger adjustment. For employees in corporate functions and the Asset Resolution Unit, the negative adjustment only applies in the event of a negative ROE of the Group and is not linked to the performance of the divisions. The basis for the ROE calculation may vary from year to year, depending on the Compensation Committee’s determination for the year in which the performance shares are granted. On February 19, 2021, the Group granted 37.8 million performance share awards with a total value of CHF 493 million. The number of performance share awards granted to employees was generally determined by dividing the deferred component of variable compensation being granted as performance share awards by the average price of a Group share over the ten consecutive trading days which ended on March 4, 2021. The fair value of each performance share award was CHF 12.59, the Group share price on the grant date. The majority of performance share awards granted include the right to receive dividend equivalents on vested shares. The estimated unrecognized compensation expense of CHF 453 million was determined based on the fair value of the awards on the grant date, includes the current estimated outcome of the relevant performance criteria and estimated future forfeitures and will be recognized over the vesting period, subject to early retirement rules.

CCA are scheduled to vest on the third anniversary of the grant date, other than those granted to individuals classified as risk managers or senior managers under the UK PRA Remuneration Code or similar regulations in other jurisdictions, where CCA vest on the fifth and seventh anniversaries of the grant date, respectively, and will be expensed over the vesting period. CCA generally provide a conditional right to receive semi-annual cash payments of interest equivalents until settled, with rates being dependent upon the vesting period and currency of denomination. CCA granted in 2021, 2020 and 2019 that vest five or seven years from the date of grant are not eligible for semi-annual cash payments of interest equivalents. CCA granted to certain regulated employees that vest over three years are not eligible for semi-annual cash payments of interest equivalents. ■ ■ ■ ■ ■ The rates were set in line with market conditions at the time of grant and existing high-trigger and low-trigger contingent capital instruments that the Group has issued. For CCA granted in February 2021, employees who received compensation in Swiss francs received CCA denominated in Swiss francs and all other employees received CCA denominated in US dollars. As CCA qualify as going concern loss-absorbing capital of the Group, the timing and form of distribution upon settlement is subject to approval by FINMA. At settlement, employees will receive either a contingent capital instrument or a cash payment based on the fair value of the CCA. The fair value will be determined by the Group. In the case of a cash settlement, the CCA award will be converted into the local currency of each respective employee. CCA have loss-absorbing features such that prior to settlement, the principal amount of the CCA would be written down to zero and forfeited if any of the following trigger events were to occur: ■ ■ On February 19, 2021, the Group awarded CHF 253 million of CCA that will be expensed over the vesting period. The estimated unrecognized compensation expense of CHF 241 million was determined based on the fair value of the awards on the grant date, including the current estimated outcome of the relevant performance criteria and estimated future forfeitures. This will be recognized over the vesting period, subject to early retirement rules. Contingent Capital Awards granted for previous years For compensation year 2020 2019 2018 CCA awarded (CHF million) 253 268 299 Deferred cash awards Deferred cash awards include certain special awards as well as voluntary deferred compensation plans and employee investment plans. For certain special awards, compensation expense was primarily driven by their vesting schedule; for other deferred cash awards, compensation expense was driven by mark to market and performance adjustments, as the majority of the awards are fully vested. Deferred fixed cash awards The Group granted deferred fixed cash compensation during 2020, 2019 and 2018 of CHF 120 million, CHF 108 million and CHF 98 million, respectively, to certain employees in the Americas. This compensation has been expensed in the Investment Bank and International Wealth Management divisions over a three-year vesting period from the grant date. Amortization of this compensation in 2020 totaled CHF 112 million, of which CHF 65 million was related to awards granted in 2020. Upfront cash awards In February 2021, certain managing directors and directors in International Wealth Management were granted CHF 59 million of upfront cash awards as part of the cash component of their 2020 variable compensation. During 2020 and 2019, the Group granted upfront cash awards of CHF 146 million and CHF 47 million, respectively. These awards are subject to repayment (clawback) by the employee in the event of voluntary resignation, termination for cause or in connection with other specified events or conditions within three years of the award grant. The amount subject to repayment is reduced in equal monthly installments during the three-year period following the grant date. The expense recognition will occur over the three-year vesting period, subject to service conditions. Amortization of this compensation in 2020 totaled CHF 79 million. Retention awards The Group granted deferred cash and stock retention awards during 2020, 2019 and 2018 of CHF 40 million, CHF 40 million and CHF 25 million, respectively. These awards are expensed over the applicable vesting period from the grant date. Amortization of these awards in 2020 totaled CHF 43 million, of which CHF 13 million was related to awards granted in 2020. Delivered shares The Group fully covered its share delivery obligations through market purchases in 2020, 2019 and 2018.

These awards are subject to repayment (clawback) by the employee in the event of voluntary resignation, termination for cause or in connection with other specified events or conditions within three years of the award grant. The amount subject to repayment is reduced in equal monthly installments during the three-year period following the grant date. The expense recognition will occur over the three-year vesting period, subject to service conditions. Amortization of this compensation in 2020 totaled CHF 79 million. Retention awards The Bank granted deferred cash and stock retention awards during 2020, 2019 and 2018 of CHF 40 million, CHF 40 million and CHF 25 million, respectively. These awards are expensed over the applicable vesting period from the grant date. Amortization of these awards in 2020 totaled CHF 43 million, of which CHF 13 million was related to awards granted in 2020.

Related party loans Executive Board and Board of Directors loans The majority of loans outstanding to members of the Executive Board and the Board of Directors are mortgages or loans against securities. All mortgage loans to members of the Executive Board are granted either with variable or fixed interest rates over a certain period. Typically, mortgages are granted for periods of up to ten years. Interest rates applied are based on refinancing costs plus a margin, and interest rates and other terms are consistent with those applicable to other employees. Loans against securities are granted at interest rates and on terms applicable to such loans granted to other employees. The same credit approval and risk assessment procedures apply to members of the Executive Board as for other employees. The highest loan outstanding to an Executive Board member was CHF 6 million to Thomas Gottstein as of December 31, 2020. Members of the Board of Directors with loans, including the Chairman of the Board of Directors, do not benefit from employee conditions, but are subject to conditions applied to clients with a comparable credit standing. Unless otherwise noted, all loans to members of the Executive Board and the Board of Directors were made in the ordinary course of business and substantially on the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other persons.

Pension and other post-retirement benefits	32 Pension and other post-retirement benefits The Group sponsors defined contribution pension plans, defined benefit pension plans and other post-retirement defined benefit plans. Defined contribution pension plans Defined contribution plans provide each participant with an individual account. The benefits to be provided to a participant are solely based on the contributions made to that employee’s account and are affected by income, expenses and gains and losses allocated to the account. As such, there are no stipulations of a defined annuity benefit at retirement and the participants bear the full actuarial as well as investment risk. The Group contributes to various defined contribution pension plans primarily in Switzerland, the US and the UK as well as other countries throughout the world. During 2020, 2019 and 2018, the Group contributed to these plans and recognized as expense CHF 299 million, CHF 167 million and CHF 153 million, respectively. This included expenses of CHF 143 million in 2020 related to the new Swiss defined contribution pension plan which took effect on January 1, 2020. Defined benefit pension and other post-retirement defined benefit plans Defined benefit pension plans Defined benefit pension plans are pension plans that define specific benefits for an employee upon that employee’s retirement. These benefits are usually determined by taking into account the employee’s salary, years of service and age of retirement. Retirees bear neither the actuarial risk (for example, the risk that the retirees of the plan live longer than expected), nor the investment risk (that is, that plan assets invested and associated returns will be insufficient to meet the expected benefits due to low or negative returns on contributions). The Group’s funding policy for these plans is in accordance with local laws and tax requirements. Swiss pension plan The Group’s most significant defined benefit pension plan, the Credit Suisse Swiss Pension Plan (Swiss pension plan), is located and covers its employees in Switzerland and is set up as a trust domiciled in Zurich. The Swiss pension plan provides benefits in the event of retirement, death and disability and meets or exceeds the minimum benefits required under the Swiss Federal Law on Occupational Retirement, Survivors’ and Disability Pension Plans (BVG). Benefits in the Swiss pension plan are determined on the basis of the accumulated employer and employee contributions and accumulated interest credited. Although the Swiss pension plan is largely defined contribution in nature, it is treated as a defined benefit plan under US GAAP, mainly due to a guaranteed minimum return on contributions and guaranteed payment of lifetime pensions. As of December 31, 2020 and 2019, the Swiss pension plan comprised 66% 71% 81% 81% 82% 82% Employee contributions in the savings section depend on their age and are determined as a percentage of the pensionable salary. The employees can select between three different levels of contributions which vary between 5% 14% 7.5% 25% The Swiss Federal council sets the minimum statutory interest rate on savings balances on an annual basis that applies to the BVG minimum pensionable salary ( 1.0% When employees retire, their savings balance is converted into an annuity and the conversion rate is the percentage used to convert the assets accrued in the Swiss pension plan to an annual lifetime retirement pension. The level of the conversion rate depends on the life expectancy of future retirees and on the long-term potential for returns in the capital markets. The Board of Trustees of the Swiss pension plan has the responsibility to set the conversion rates for the plan. Decisions on conversion rates are to be set for a planning horizon of at least seven years. International pension plans Various defined benefit pension plans cover the Group’s employees outside Switzerland. These plans provide benefits in the event of retirement, death, disability or termination of employment. Retirement benefits under the international pension plans depend on age, contributions and salary. The Group’s principal defined benefit pension plans outside Switzerland are located in the US and in the UK. Both of these plans are funded, closed to new participants and have ceased accruing new benefits. Smaller defined benefit pension plans, both funded and unfunded, are operated in other locations. Other post-retirement defined benefit plan In the US, the Group has a defined benefit plan that provides post-retirement benefits other than pension benefits that primarily focus on health and welfare benefits for certain retired employees. In exchange for the current services provided by the employee, the Group promises to provide health and welfare benefits after the employee retires. The Group’s obligation for that compensation is incurred as employees render the services necessary to earn their post-retirement benefits.

Other components of net periodic benefit costs are reflected in general and administrative expenses or, except for 2019, in restructuring expenses. Net periodic benefit costs of defined benefit plans The net periodic benefit costs for defined benefit pension and other post-retirement defined benefit plans are the costs of the respective plan for a period during which an employee renders services. The actual amount to be recognized is determined using the standard actuarial methodology which considers, among other factors, current service cost, interest cost, expected return on plan assets and the amortization of both prior service costs/(credits) and actuarial losses/(gains) recognized in AOCI. Service costs on benefit obligation reflected in compensation and benefits – other for 2020, 2019 and 2018 were CHF 218 million, CHF 270 million and CHF 258 million, respectively. As part of its strategic plan, the Group has launched a number of cost efficiency measures, including headcount reduction. This resulted in curtailment gains of CHF 10 million and CHF 12 million in 2020 and 2018, respectively, reflecting the immediate recognition of a credit relating to the years of service no longer expected to be rendered. Additional costs of CHF 8 million, CHF 41 million and CHF 35 million in 2020, 2019 and 2018, respectively, related to the settlement of the pension obligation for employees in Switzerland whose employment has effectively been terminated or who have left the Group due to a sale of their business. Special termination benefit costs of CHF 8 million, CHF 14 million and CHF 38 million have been recognized in 2020, 2019 and 2018, respectively, relating to early retirements in Switzerland in the context of the cost efficiency measures. Benefit obligation The benefit obligation is expressed as either accumulated benefit obligation (ABO) or PBO. While the ABO refers to the actuarial present value based on employee services rendered prior to that date and takes into account current and past compensation levels, the PBO also applies an assumption as to future compensation levels. The “Obligations and funded status of the plans” table shows the changes in the PBO, the ABO, the fair value of plan assets and the amounts recognized in the consolidated balance sheets for the defined benefit pension and other post-retirement defined benefit plans. US GAAP requires an employer to recognize the funded status of the defined benefit pension and other post-retirement defined benefit plans on the balance sheet. The funded status of these plans is determined as the difference between the fair value of plan assets and the PBO. The funded status may vary from year to year due to changes in the fair value of plan assets and variations of the PBO following changes in the underlying assumptions and membership data used to determine the PBO. In 2020 and 2019, the curtailments, settlements and special termination benefits in Switzerland, which impacted the PBO, related to the headcount reduction in the context of the cost efficiency measures.

The remeasurement loss on the international pension plans recorded as of December 31, 2020 consisted of losses on the PBO of CHF 456 million due to changes in financial and demographic assumptions, primarily a decrease in the discount rate and updates on the membership data, partially offset by gains on the asset portfolio of CHF 391 million. The remeasurement loss on the international pension plans recorded as of December 31, 2019 consisted of losses on the PBO of CHF 410 million due to changes in financial and demographic assumptions, primarily a decrease in the discount rate and updates on the membership data, partially offset by gains on the asset portfolio of CHF 379 million. In 2020, there was a special cash contribution made to the defined benefit pension plan in the US of CHF 43 million. In 2019, a special cash contribution was made to the defined benefit pension plan in Germany of CHF 111 million. In 2021, the Group expects to contribute CHF 296 million to the Swiss pension plan, CHF 16 million to the international defined benefit pension plans and CHF 11 million to other post-retirement defined benefit plans.

The discount rates are determined based on yield curves, constructed from high-quality corporate bonds currently available and observable in the market and are expected to be available during the period to maturity of the pension benefits. In countries where there is no deep market in high-quality corporate bonds with longer durations, the best available market information, including governmental bond yields and risk premiums, is used to construct the yield curve. Credit Suisse uses the spot rate approach for valuations, whereby individual spot rates on the yield curve are applied to each year’s cash flow in measuring the plan’s benefit obligation as well as future service costs and interest costs. The assumption pertaining to salary increases is used to calculate the PBO, which is measured using an assumption as to future compensation levels. Credit Suisse estimates the future interest rate on savings balances taking into consideration actions and rates approved by the Board of Trustees of the Swiss pension plan and expected future changes in the interest rate environment. In prior years, Credit Suisse used the cash flow weighted-average of the yield curve used for the discount rate as the best estimate for the interest rate on savings balances for these long-term projections. Due to the higher actual interest rate on savings balances payments over prior years, the interest rate on savings balances has been updated to 1.25% The expected long-term rate of return on plan assets assumption is applied to the market-related value of assets to calculate the expected return on plan assets as a component of the net periodic benefit costs. It reflects the average rate of returns expected on the funds invested or to be invested to provide for the benefits included in the PBO. In estimating that rate, appropriate consideration is given to the returns being earned by the plan assets and the rates of return expected to be available for reinvestment. The expected long-term rate of return on plan assets is based on total return forecasts, expected volatility and correlation estimates, reflecting interrelationships between and within asset classes held. Where possible, similar, if not related, approaches are followed to forecast returns for the various asset classes. The expected long-term rate of return on debt securities reflects both accruing interest and price returns. The probable long-term relationship between the total return and certain exogenous variables is used, which links the total return forecasts on debt securities to forecasts of the macroeconomic environment. The expected long-term rate of ROE securities is based on a two-stage dividend discount model which considers economic and market forecasts to compute a market-implied equity risk premium. Dividends are estimated using market consensus earnings and the historical payout ratio. A subsequent scenario analysis is used to stress test the level of the return. The expected long-term rate of return on real estate is based on economic models that reflect both the rental and the capital market side of the direct real estate market. This allows for a replicable and robust forecasting methodology for expected returns on real estate equity, fund and direct market indices. The expected long-term rate of return on private equity and hedge funds is estimated by determining the key factors in their historical performance using private equity and hedge fund benchmarks and indices. To capture these factors, multiple linear regression models with lagged returns are used. Mortality assumptions are based on standard mortality tables and standard models and methodologies for projecting future improvements to mortality as developed and published by external independent actuarial societies and actuarial organizations.

Under US GAAP, the assumptions used to value the PBO should always represent the best estimate as of the measurement date. Credit Suisse regularly reviews the actuarial assumptions used to value and measure the defined benefit obligation on a periodic basis as required by US GAAP. Health care cost assumptions The health care cost trend is used to determine the appropriate other post-retirement defined benefit costs. In determining those costs, an annual weighted-average rate is assumed in the cost of covered health care benefits. The following table provides an overview of the assumed health care cost trend rates. Health care cost trend rates in / end of 2020 2019 2018 Health care cost trend rate (%) Annual weighted-average health care cost trend rate 1 7.0 8.0 8.7 1 The annual health care cost trend rate is assumed to decrease gradually to achieve the long-term health care cost trend rate of 5% by 2025. The annual health care cost trend rate used to determine the net periodic defined benefit costs for 2021 is 7.0% Plan assets and investment strategy Plan assets, which are assets that have been segregated and restricted to provide for plan benefits, are measured at their fair value as of the measurement date. The Group’s defined benefit pension plans employ a total return investment approach, whereby a diversified mix of debt and equity securities and alternative investments, specifically hedge funds and private equity, are used to maximize the long-term return of plan assets while incurring a prudent level of risk. The intent of this strategy is to meet or outperform plan liabilities over the long term. Risk tolerance is established through careful consideration of plan liabilities, plan funded status and corporate financial condition. Furthermore, equity securities are diversified across different geographic regions as well as across growth, value and small and large capitalization stocks. Real estate and alternative investments, such as private equity and hedge funds, are used to enhance long-term returns while improving portfolio diversification. Derivatives may be used to hedge or increase market exposure, but are not used to leverage the portfolio beyond the market value of the underlying investments. Investment risk is measured and monitored on an ongoing basis through periodic asset/liability studies and quarterly investment portfolio reviews. To limit investment risk, the Group pension plans follow defined strategic asset allocation guidelines. At times of major market uncertainties and stress, these guidelines may be further restricted. As of December 31, 2020 and 2019, the total fair value of Group equity securities and options was CHF 77 million and CHF 89 million, respectively. Fair value hierarchy of plan assets > Refer to “Fair value measurement” in Note 36 – Financial instruments for discussion of the fair value hierarchy. Fair value of plan assets The following tables present the plan assets measured at fair value on a recurring basis as of December 31, 2020 and 2019 for the Group’s defined benefit pension plans.

Valuations of money market instruments and commingled funds are generally based on observable inputs. Debt securities Debt securities include government and corporate bonds which are generally quoted in active markets or as units in mutual funds. Debt securities for which market prices are not available, are valued based on yields reflecting the perceived risk of the issuer and the maturity of the security, recent disposals in the market or other modeling techniques, which may involve judgment. Units in mutual funds which are not directly quoted on a public stock exchange and/or for which a fair value is not readily determinable are measured at fair value using NAV. Equity securities Equity securities held include common equity shares, convertible bonds and shares in investment companies and units in mutual funds. The common equity shares are generally traded on public stock exchanges for which quoted prices are regularly available. Convertible bonds are generally valued using observable pricing sources. Shares in investment companies and units in mutual funds, which are not directly quoted on a public stock exchange and/or for which a fair value is not readily determinable, are measured at fair value using NAV. Real estate Real estate includes direct real estate as well as investments in real estate investment companies, trusts or mutual funds. Direct real estate is initially measured at its transaction price, which is the best estimate of fair value. Thereafter, direct real estate is individually measured at fair value based on a number of factors that include any recent rounds of financing involving third-party investors, comparable company transactions, multiple analyses of cash flows or book values, or discounted cash flow analyses. The availability of information used in these modeling techniques is often limited and involves significant judgment in evaluating these different factors over time. Real estate investment companies, trusts and mutual funds which are not directly quoted on a public stock exchange and/or for which a fair value is not readily determinable are measured at fair value using NAV. Alternative investments Private equity includes direct investments, investments in partnerships that make private equity and related investments in various portfolio companies and funds and fund of funds partnerships. Private equity consists of both publicly traded securities and private securities. Publicly traded investments that are restricted or that are not quoted in active markets are valued based on publicly available quotes with appropriate adjustments for liquidity or trading restrictions. Private equity is valued taking into account a number of factors, such as the most recent round of financing involving unrelated new investors, earnings multiple analyses using comparable companies or discounted cash flow analyses. Private equity for which a fair value is not readily determinable is measured at fair value using NAV provided by the general partner. Hedge funds that are not directly quoted on a public stock exchange and/or for which a fair value is not readily determinable are measured at fair value using NAV provided by the fund administrator. Derivatives Derivatives include both OTC and exchange-traded derivatives. The fair value of OTC derivatives is determined on the basis of inputs that include those characteristics of the derivative that have a bearing on the economics of the instrument. The determination of the fair value of many derivatives involves only a limited degree of subjectivity since the required inputs are generally observable in the marketplace. Other more complex derivatives may use unobservable inputs. Such inputs include long-dated volatility assumptions on OTC option transactions and recovery rate assumptions for credit derivative transactions. The fair value of exchange-traded derivatives is typically derived from the observable exchange prices and/or observable inputs. Plan asset allocation The following table shows the plan asset allocation as of the measurement date calculated based on the fair value at that date including the performance of each asset class.

Pension and other post-retirement benefits	31 Pension and other post-retirement benefits The Bank participates in a defined benefit pension plan sponsored by the Group and has defined contribution pension plans, single-employer defined benefit pension plans and other post-retirement defined benefit plans. The Bank’s principal plans are located in Switzerland, the US and the UK. > Refer to “Note 32 – Pension and other post-retirement benefits” in VI – Consolidated financial statements – Credit Suisse Group for further information on pension and other post-retirement benefits. Defined contribution pension plans The Bank contributes to various defined contribution pension plans primarily in Switzerland, the US and the UK as well as other countries throughout the world. During 2020, 2019 and 2018, the Bank contributed to these plans and recognized as expense CHF 240 million, CHF 150 million and CHF 140 million, respectively. This included expenses of CHF 96 million in 2020 related to the new Swiss defined contribution pension plan which took effect on January 1, 2020. Defined benefit pension and other post-retirement benefit plans Defined benefit pension plans Group pension plan The Bank covers pension requirements for its employees in Switzerland by participating in a defined benefit pension plan sponsored by the Group (Group plan), the Group’s most significant defined benefit pension plan. The Group plan provides benefits in the event of retirement, death and disability. Various legal entities within the Group participate in the Group plan, which is set up as an independent trust domiciled in Zurich. Benefits in the Group plan are determined on the basis of the accumulated employer and employee contributions and accumulated interest credited. In accordance with US GAAP, the Group accounts for the Group plan as a single-employer defined benefit pension plan and uses the projected unit credit actuarial method to determine the net periodic benefit costs, the PBO and the accumulated benefit obligation (ABO). The Bank accounts for the defined benefit pension plan sponsored by the Group as a multi-employer pension plan because other legal entities within the Group also participate in the Group plan and the assets contributed by the Bank are not segregated into a separate account or restricted to provide benefits only to employees of the Bank. The assets contributed by the Bank are commingled with the assets contributed by the other legal entities of the Group and can be used to provide benefits to any employee of any participating legal entity. The Bank’s contributions to the Group plan comprise 84% The Bank accounts for the Group plan on a defined contribution basis whereby it only recognizes the amounts required to be contributed to the Group plan during the period as net periodic pension expense and only recognizes a liability for any contributions due and unpaid. No other expenses or balance sheet amounts related to the Group plan were recognized by the Bank. In the savings section of the Group plan, the Bank’s contribution varies between 7.5% 25.0% During 2020, 2019 and 2018, the Bank contributed and recognized as expense CHF 249 million, CHF 338 million and CHF 377 million to the Group plan, respectively. The Bank expects to contribute CHF 249 million to the Group plan during 2021. International pension plans Various defined benefit pension plans cover the Bank’s employees outside Switzerland. These plans provide benefits in the event of retirement, death, disability or termination of employment. Retirement benefits under the plans depend on age, contributions and salary. The Bank’s principal defined benefit pension plans outside Switzerland are located in the US and in the UK. Both plans are funded, closed to new participants and have ceased accruing new benefits. Smaller defined benefit pension plans, both funded and unfunded, are operated in other locations. Other post-retirement defined benefit plan In the US, the Bank has a defined benefit plan that provides post-retirement benefits other than pension benefits that primarily focus on health and welfare benefits for certain retired employees. In exchange for the current services provided by the employee, the Bank promises to provide health and welfare benefits after the employee retires. The Bank’s obligation for that compensation is incurred as employees render the services necessary to earn their post-retirement benefits. Net periodic benefit costs of defined benefit plans The net periodic benefit costs for defined benefit pension and other post-retirement defined benefit plans are the costs of the respective plan for a period during which an employee renders services. The actual amount to be recognized is determined using the standard actuarial methodology which considers, among other factors, current service cost, interest cost, expected return on plan assets and the amortization of both prior service costs/(credits) and actuarial losses/(gains) recognized in AOCI. Components of net periodic benefit costs International single-employer Other post-retirement in 2020 2019 2018 2020 2019 2018 Net periodic benefit costs (CHF million) Service costs on benefit obligation 14 14 16 0 0 0 Interest costs on benefit obligation 68 90 86 4 6 5 Expected return on plan assets (85) (108) (114) 0 0 0 Amortization of recognized prior service cost/(credit) 1 1 0 0 0 0 Amortization of recognized actuarial losses/(gains) 13 19 47 1 3 8 Settlement losses/(gains) (1) 0 0 0 0 0 Curtailment losses/(gains) 0 0 (1) 0 0 0 Net periodic benefit costs/(credits) 10 16 34 5 9 13 Service costs on benefit obligation are reflected in compensation and benefits.

In 2020, there was a special cash contribution made to the defined benefit pension plan in the US of CHF 43 million. In 2019, a special cash contribution was made to the defined benefit pension plan in Germany of CHF 111 million. In 2021, the Bank expects to contribute CHF 16 million to the international single-employer defined benefit pension plans and CHF 11 million to other post-retirement defined benefit plans.

Derivatives and hedging activities	33 Derivatives and hedging activities Derivatives are generally either privately negotiated OTC contracts or standard contracts transacted through regulated exchanges. The Group’s most frequently used freestanding derivative products, entered into for trading and risk management purposes, include interest rate, credit default and cross-currency swaps, interest rate and foreign exchange options, interest rate and foreign exchange forward contracts and foreign exchange and interest rate futures. The Group also enters into contracts that are not considered derivatives in their entirety but include embedded derivative features. Such transactions primarily include issued and purchased structured debt instruments where the return may be calculated by reference to an equity security, index or third-party credit risk, or that have non-standard interest or foreign exchange terms. On the date a derivative contract is entered into, the Group designates it as belonging to one of the following categories: ■ ■ ■ ■ ■ Trading activities The Group is active in most of the principal trading markets and transacts in many trading and hedging products. As noted above, this includes the use of swaps, futures, options and structured products, such as custom transactions using combinations of derivatives, in connection with its sales and trading activities. Trading activities include market making, positioning and arbitrage activities. The majority of the Group’s derivatives were used for trading activities. Economic hedges Economic hedges arise when the Group enters into derivative contracts for its own risk management purposes, but the contracts entered into do not qualify for hedge accounting under US GAAP. These economic hedges include the following types: ■ ■ ■ ■ ■ Derivatives used in economic hedges are included as trading assets or trading liabilities in the consolidated balance sheets. Hedge accounting Fair value hedges The Group designates fair value hedges as part of an overall interest rate risk management strategy that incorporates the use of derivative instruments to minimize fluctuations in earnings that are caused by interest rate volatility. The Group uses derivatives to hedge for changes in fair value as a result of the interest rate risk associated with loans, debt securities held as available-for-sale and long-term debt instruments. Cash flow hedges The Group hedges the variability in interest cash flows on mortgages and loans by using interest rate swaps to convert variable rate assets to fixed rates. Further, the Group uses foreign currency forwards to hedge the foreign currency risk associated with certain forecasted transactions. As of the end of 2020, the maximum length of time over which the Group hedged its exposure to the variability in future cash flows for forecasted transactions, excluding those forecasted transactions related to the payment of variable interest on existing financial instruments, was 12 months. Net investment hedges The Group designates net investment hedges as part of its strategy to hedge selected net investments in foreign operations against adverse movements in foreign exchange rates, typically using forward foreign exchange contracts. Hedge effectiveness assessment The Group assesses the effectiveness of hedging relationships both prospectively and retrospectively. The prospective assessment is made both at the inception of a hedging relationship and on an ongoing basis, and requires the Group to justify its expectation that the relationship will be highly effective over future periods. The retrospective assessment is also performed on an ongoing basis and requires the Group to determine whether or not the hedging relationship has actually been effective. Fair value of derivative instruments The tables below present gross derivative replacement values by type of contract and whether the derivative is used for trading purposes or in a qualifying hedging relationship. Notional amounts have also been provided as an indication of the volume of derivative activity within the Group. Information on bifurcated embedded derivatives has not been included in these tables. Under US GAAP, the Group elected to account for substantially all financial instruments with an embedded derivative that is not considered clearly and closely related to the host contract at fair value. > Refer to “Note 36 – Financial instruments” for further information.

Disclosures relating to contingent credit risk Certain of the Group’s derivative instruments contain provisions that require it to maintain a specified credit rating from each of the major credit rating agencies. If the ratings fall below the level specified in the contract, the counterparties to the agreements could request payment of additional collateral on those derivative instruments that are in a net liability position. Certain of the derivative contracts also provide for termination of the contract, generally upon a downgrade of either the Group or the counterparty. Such derivative contracts are reflected at close-out costs. The following table provides the Group’s current net exposure from contingent credit risk relating to derivative contracts with bilateral counterparties and SPEs that include credit support agreements, the related collateral posted and the additional collateral required in a one-notch, two-notch and a three-notch downgrade event, respectively. The table also includes derivative contracts with contingent credit risk features without credit support agreements that have accelerated termination event conditions. The current net exposure for derivative contracts with bilateral counterparties and contracts with accelerated termination event conditions is the aggregate fair value of derivative instruments that were in a net liability position. For SPEs, the current net exposure is the contractual amount that is used to determine the collateral payable in the event of a downgrade. The contractual amount could include both the NRV and a percentage of the notional value of the derivative.

Credit derivatives Credit derivatives are contractual agreements in which the buyer generally pays a fee in exchange for a contingent payment by the seller if there is a credit event on the underlying referenced entity or asset. They are generally privately negotiated OTC contracts, with numerous settlement and payment terms, and most are structured so that they specify the occurrence of an identifiable credit event, which can include bankruptcy, insolvency, receivership, material adverse restructuring of debt or failure to meet obligations when due. The Group enters into credit derivative contracts in the normal course of business, buying and selling protection to facilitate client transactions and as a market maker. This includes providing structured credit products for its clients to enable them to hedge their credit risk. The referenced instruments of these structured credit products are both investment grade and non-investment grade and could include corporate bonds, sovereign debt, asset-backed securities (ABS) and loans. These instruments can be formed as single items (single-named instruments) or combined on a portfolio basis (multi-named instruments). The Group purchases protection to economically hedge various forms of credit exposure, for example, the economic hedging of loan portfolios or other cash positions. Finally, the Group also takes proprietary positions which can take the form of either purchased or sold protection. The credit derivatives most commonly transacted by the Group are CDS and credit swaptions. CDSs are contractual agreements in which the buyer of the swap pays an upfront and/or a periodic fee in return for a contingent payment by the seller of the swap following a credit event of the referenced entity or asset. Credit swaptions are options with a specified maturity to buy or sell protection under a CDS on a specific referenced credit event. In addition, to reduce its credit risk, the Group enters into legally enforceable netting agreements with its derivative counterparties. Collateral on these derivative contracts is usually posted on a net counterparty basis and cannot be allocated to a particular derivative contract. > Refer to “Note 28 – Offsetting of financial assets and financial liabilities” for further information on netting. Credit protection sold Credit protection sold is the maximum potential payout, which is based on the notional value of derivatives and represents the amount of future payments that the Group would be required to make as a result of credit risk-related events. The Group believes that the maximum potential payout is not representative of the actual loss exposure based on historical experience. This amount has not been reduced by the Group’s rights to the underlying assets and the related cash flows. In accordance with most credit derivative contracts, should a credit event (or settlement trigger) occur, the Group is usually liable for the difference between the credit protection sold and the recourse it holds in the value of the underlying assets. The maximum potential amount of future payments has not been reduced for any cash collateral paid to a given counterparty as such payments would be calculated after netting all derivative exposures, including any credit derivatives with that counterparty in accordance with a related master netting agreement. Due to such netting processes, determining the amount of collateral that corresponds to credit derivative exposures only is not possible. To reflect the quality of the payment risk on credit protection sold, the Group assigns an internally generated rating to those instruments referenced in the contracts. Internal ratings are assigned by experienced credit analysts based on expert judgment that incorporates analysis and evaluation of both quantitative and qualitative factors. The specific factors analyzed, and their relative importance, are dependent on the type of counterparty. The analysis emphasizes a forward-looking approach, concentrating on economic trends and financial fundamentals, and making use of peer analysis, industry comparisons and other quantitative tools. External ratings and market information are also used in the analysis process where available. Credit protection purchased Credit protection purchased represents those instruments where the underlying reference instrument is identical to the reference instrument of the credit protection sold. The maximum potential payout amount of credit protection purchased for each individual identical underlying reference instrument may be greater or lower than the notional amount of protection sold. The Group also considers estimated recoveries that it would receive if the specified credit event occurred, including both the anticipated value of the underlying referenced asset that would, in most instances, be transferred to the Group and the impact of any purchased protection with an identical reference instrument and product type. Other protection purchased In the normal course of business, the Group purchases protection to offset the risk of credit protection sold that may have similar, but not identical, reference instruments, and may use similar, but not identical, products, which reduces the total credit derivative exposure. Other protection purchased is based on the notional value of the instruments. The Group purchases its protection from banks and broker dealers, other financial institutions and other counterparties. Fair value of credit protection sold The fair values of the credit protection sold give an indication of the amount of payment risk, as the negative fair values increase when the potential payment under the derivative contracts becomes more probable. Credit protection sold/purchased The following tables do not include all credit derivatives and differ from the credit derivatives in the “Fair value of derivative instruments” table. This is due to the exclusion of certain credit derivative instruments under US GAAP, which defines a credit derivative as a derivative instrument (a) in which one or more of its underlyings are related to the credit risk of a specified entity (or a group of entities) or an index based on the credit risk of a group of entities and (b) that exposes the seller to potential loss from credit risk-related events specified in the contract. Total return swaps (TRS) of CHF 14.4 billion and CHF 16.7 billion as of December 31, 2020 and 2019, respectively, were also excluded because a TRS does not expose the seller to potential loss from credit risk-related events specified in the contract. A TRS only provides protection against a loss in asset value and not against additional amounts as a result of specific credit events.

Disclosures relating to contingent credit risk The following table provides the Bank’s current net exposure from contingent credit risk relating to derivative contracts with bilateral counterparties and special purpose entities (SPEs) that include credit support agreements, the related collateral posted and the additional collateral required in a one-notch, two-notch and a three-notch downgrade event, respectively. The table also includes derivative contracts with contingent credit risk features without credit support agreements that have accelerated termination event conditions. The current net exposure for derivative contracts with bilateral counterparties and contracts with accelerated termination event conditions is the aggregate fair value of derivative instruments that were in a net liability position. For SPEs, the current net exposure is the contractual amount that is used to determine the collateral payable in the event of a downgrade. The contractual amount could include both the negative replacement value and a percentage of the notional value of the derivative.

Credit derivatives > Refer to “Note 33 – Derivatives and hedging activities” in VI – Consolidated financial statements – Credit Suisse Group for further information. Credit protection sold/purchased The following tables do not include all credit derivatives and differ from the credit derivatives in the “Fair value of derivative instruments” table. This is due to the exclusion of certain credit derivative instruments under US GAAP, which defines a credit derivative as a derivative instrument (a) in which one or more of its underlyings are related to the credit risk of a specified entity (or a group of entities) or an index based on the credit risk of a group of entities and (b) that exposes the seller to potential loss from credit risk-related events specified in the contract. Total return swaps (TRS) of CHF 14.4 billion and CHF 16.7 billion as of December 31, 2020 and 2019, respectively, were also excluded because a TRS does not expose the seller to potential loss from credit risk-related events specified in the contract. A TRS only provides protection against a loss in asset value and not against additional amounts as a result of specific credit events.

Guarantees and commitments

Guarantees and commitments	12 Months Ended
	Dec. 31, 2020
Guarantees and commitments	34 Guarantees and commitments Guarantees In the ordinary course of business, guarantees are provided that contingently obligate the Group to make payments to third parties if the counterparty fails to fulfill its obligation under a borrowing or other contractual arrangement. The total gross amount disclosed within the Guarantees table reflects the maximum potential payment under the guarantees. The carrying value represents the higher of the initial fair value (generally the related fee received or receivable) less cumulative amortization and the Group’s current best estimate of payments that will be required under existing guarantee arrangements. Guarantees provided by the Group are classified as follows: credit guarantees and similar instruments, performance guarantees and similar instruments, derivatives and other guarantees. Guarantees Maturity 1 Maturity Maturity Maturity 1 2 2020 (CHF million) Credit guarantees and similar instruments 1,645 649 203 582 3,079 3,016 27 1,637 Performance guarantees and similar instruments 3,607 1,885 526 514 6,532 5,601 30 2,535 Derivatives 3 10,531 3,921 698 1,423 16,573 16,573 380 – 4 Other guarantees 3,555 996 421 1,171 6,143 6,130 85 3,725 Total guarantees 19,338 7,451 1,848 3,690 32,327 31,320 522 7,897 2019 (CHF million) Credit guarantees and similar instruments 1,813 252 185 864 3,114 3,061 10 1,655 Performance guarantees and similar instruments 4,407 3,059 668 723 8,857 7,833 31 2,793 Derivatives 3 13,194 2,665 695 690 17,244 17,244 295 – 4 Other guarantees 3,507 1,386 367 1,243 6,503 6,457 64 4,003 Total guarantees 22,921 7,362 1,915 3,520 35,718 34,595 400 8,451 1 Prior period has been corrected. 2 Total net amount is computed as the gross amount less any participations. 3 Excludes derivative contracts with certain active commercial and investment banks and certain other counterparties, as such contracts can be cash settled and the Group had no basis to conclude it was probable that the counterparties held, at inception, the underlying instruments. 4 Collateral for derivatives accounted for as guarantees is not significant. Credit guarantees and similar instruments Credit guarantees and similar instruments are contracts that require the Group to make payments should a third party fail to do so under a specified existing credit obligation. The position includes standby letters of credit, commercial and residential mortgage guarantees, credit guarantees to clearing and settlement networks and exchanges and other guarantees associated with VIEs. Standby letters of credit are made in connection with the corporate lending business and other corporate activities, where the Group provides guarantees to counterparties in the form of standby letters of credit, which represent obligations to make payments to third parties if the counterparties fail to fulfill their obligations under a borrowing arrangement or other contractual obligation. Commercial and residential mortgage guarantees are made in connection with the Group’s commercial mortgage activities in the US, where the Group sells certain commercial and residential mortgages to Fannie Mae and agrees to bear a percentage of the losses triggered by the borrowers failing to perform on the mortgage. The Group also issues guarantees that require it to reimburse Fannie Mae for losses on certain whole loans underlying mortgage-backed securities issued by Fannie Mae, which are triggered by borrowers failing to perform on the underlying mortgages. The Group also provides guarantees to VIEs and other counterparties under which it may be required to buy assets from such entities upon the occurrence of certain triggering events such as rating downgrades and/or substantial decreases in the fair value of those assets. Performance guarantees and similar instruments Performance guarantees and similar instruments are arrangements that require contingent payments to be made when certain performance-related targets or covenants are not met. Such covenants may include a customer’s obligation to deliver certain products and services or to perform under a construction contract. Performance guarantees are frequently executed as part of project finance transactions. The position includes private equity fund guarantees and guarantees related to residential mortgage securitization activities. For private equity fund guarantees, the Group has provided investors in private equity funds sponsored by a Group entity guarantees on potential obligations of certain general partners to return amounts previously paid as carried interest to those general partners if the performance of the remaining investments declines. To manage its exposure, the Group generally withholds a portion of carried interest distributions to cover any repayment obligations. In addition, pursuant to certain contractual arrangements, the Group is obligated to make cash payments to certain investors in certain private equity funds if specified performance thresholds are not met. Further, as part of the Group’s residential mortgage securitization activities in the US, the Group may guarantee the collection by the servicer and remittance to the securitization trust of prepayment penalties. The Group will have to perform under these guarantees in the event the servicer fails to remit the prepayment penalties. Derivatives Derivatives which may also have the characteristics of a guarantee are issued in the ordinary course of business, generally in the form of written put options. Such derivative contracts do not meet the characteristics of a guarantee if they are cash settled and the Group has no basis to conclude it is probable that the counterparties held, at inception, the underlying instruments related to the derivative contracts. The Group has concluded that these conditions were met for certain active commercial and investment banks and certain other counterparties, and accordingly, the Group has reported such contracts as derivatives only. The Group manages its exposure to these derivatives by engaging in various hedging strategies to reduce its exposure. For some contracts, such as written interest rate caps or foreign exchange options, the maximum payout is not determinable as interest rates or exchange rates could theoretically rise without limit. For these contracts, notional amounts were disclosed in the table above in order to provide an indication of the underlying exposure. In addition, the Group carries all derivatives at fair value in the consolidated balance sheets and has considered the performance triggers and probabilities of payment when determining those fair values. It is more likely than not that written put options that are in-the-money to the counterparty will be exercised, for which the Group’s exposure was limited to the carrying value reflected in the table. Other guarantees Other guarantees include bankers’ acceptances, residual value guarantees, deposit insurance, contingent considerations in business combinations, the minimum value of an investment in mutual funds or private equity funds and all other guarantees that were not allocated to one of the categories above. Deposit-taking banks and securities dealers in Switzerland and certain other European countries are required to ensure the payout of privileged deposits in case of specified restrictions or compulsory liquidation of a deposit-taking bank. In Switzerland, deposit-taking banks and securities dealers jointly guarantee an amount of up to CHF 6 billion. Upon occurrence of a payout event triggered by a specified restriction of business imposed by FINMA or by the compulsory liquidation of another deposit-taking bank, the Group’s contribution will be calculated based on its share of privileged deposits in proportion to total privileged deposits. Based on FINMA’s estimate for the Group’s banking subsidiaries in Switzerland, the Group’s share in the deposit insurance guarantee program for the period July 1, 2020 to June 30, 2021 is CHF 0.5 billion. These deposit insurance guarantees were reflected in other guarantees. Representations and warranties on residential mortgage loans sold In connection with the Investment Bank division’s sale of US residential mortgage loans, the Group has provided certain representations and warranties relating to the loans sold. The Group has provided these representations and warranties relating to sales of loans to institutional investors, primarily banks, and non-agency, or private label, securitizations. The loans sold are primarily loans that the Group has purchased from other parties. The scope of representations and warranties, if any, depends on the transaction, but can include: ownership of the mortgage loans and legal capacity to sell the loans; loan-to-value ratios and other characteristics of the property, the borrower and the loan; validity of the liens securing the loans and absence of delinquent taxes or related liens; conformity to underwriting standards and completeness of documentation; and origination in compliance with law. If it is determined that representations and warranties were breached, the Group may be required to repurchase the related loans or indemnify the investors to make them whole for losses. Whether the Group will incur a loss in connection with repurchases and make whole payments depends on: the extent to which claims are made; the validity of such claims made within the statute of limitations (including the likelihood and ability to enforce claims); whether the Group can successfully claim against parties that sold loans to the Group and made representations and warranties to the Group; the residential real estate market, including the number of defaults; and whether the obligations of the securitization vehicles were guaranteed or insured by third parties. Repurchase claims on residential mortgage loans sold that are subject to arbitration or litigation proceedings, or become so during the reporting period, are not included in this Guarantees and commitments disclosure but are addressed in litigation and related loss contingencies and provisions. The Group is involved in litigation relating to representations and warranties on residential mortgages sold. > Refer to “Note 40 – Litigation” for further information. Disposal-related contingencies and other indemnifications The Group has certain guarantees for which its maximum contingent liability cannot be quantified. These guarantees are not reflected in the “Guarantees” table and are discussed below. Disposal-related contingencies In connection with the sale of assets or businesses, the Group sometimes provides the acquirer with certain indemnification provisions. These indemnification provisions vary by counterparty in scope and duration and depend upon the type of assets or businesses sold. They are designed to transfer the potential risk of certain unquantifiable and unknowable loss contingencies, such as litigation, tax and intellectual property matters, from the acquirer to the seller. The Group closely monitors all such contractual agreements in order to ensure that indemnification provisions are adequately provided for in the Group’s consolidated financial statements. Other indemnifications The Group provides indemnifications to certain counterparties in connection with its normal operating activities for which it is not possible to estimate the maximum amount that it could be obligated to pay. As a normal part of issuing its own securities, the Group typically agrees to reimburse holders for additional tax withholding charges or assessments resulting from changes in applicable tax laws or the interpretation of those laws. Securities that include these agreements to pay additional amounts generally also include a related redemption or call provision if the obligation to pay the additional amounts results from a change in law or its interpretation and the obligation cannot be avoided by the issuer taking reasonable steps to avoid the payment of additional amounts. Since such potential obligations are dependent on future changes in tax laws, the related liabilities the Group may incur as a result of such changes cannot be reasonably estimated. In light of the related call provisions typically included, the Group does not expect any potential liabilities in respect of tax gross-ups to be material. The Group is a member of numerous securities exchanges and clearing houses and may, as a result of its membership arrangements, be required to perform if another member defaults and available amounts as defined in the relevant exchange’s or clearing house’s default waterfalls are not sufficient to cover losses of another member’s default. The exchange’s or clearing house’s default management procedures may provide for cash calls to non-defaulting members which may be limited to the amount (or a multiple of the amount) of the Group’s contribution to the guarantee fund. However, if these cash calls are not sufficient to cover losses, the default waterfall and default management procedures may foresee further loss allocation. Furthermore, some clearing house arrangements require members to assume a proportionate share of non-default losses, if such losses exceed the specified resources allocated for such purpose by the clearing house. Non-default losses result from the clearing house’s investment of guarantee fund contributions and initial margin or are other losses unrelated to the default of a clearing member. The Group has determined that it is not possible to reasonably estimate the maximum potential amount of future payments due under the membership arrangements. In addition, the Group believes that any potential requirement to make payments under these membership arrangements is remote. Other commitments Irrevocable commitments under documentary credits Irrevocable commitments under documentary credits include exposures from trade finance related to commercial letters of credit under which the Group guarantees payments to exporters against presentation of shipping and other documents. Irrevocable loan commitments Irrevocable loan commitments are irrevocable credit facilities extended to clients and include fully or partially undrawn commitments that are legally binding and cannot be unconditionally cancelled by the Group. Commitments to originate mortgage loans that will be held for sale are considered derivatives for accounting purposes and are not included in this disclosure. Such commitments are reflected as derivatives in the consolidated balance sheets. Forward reverse repurchase agreements Forward reverse repurchase agreements represent transactions in which the initial cash exchange of the reverse repurchase transactions takes place on specified future dates. The Group enters into forward reverse repurchase agreements with counterparties that may have existing funded reverse repurchase agreements.

Transfers of financial assets and variable interest entities	35 Transfers of financial assets and variable interest entities In the normal course of business, the Group enters into transactions with, and makes use of, SPEs. An SPE is an entity in the form of a trust or other legal structure designed to fulfill a specific limited need of the company that organized it and is generally structured to isolate the SPE’s assets from creditors of other entities, including the Group. The principal uses of SPEs are to assist the Group and its clients in securitizing financial assets and creating investment products. The Group also uses SPEs for other client-driven activity, such as to facilitate financings, and for Group tax or regulatory purposes. Transfers of financial assets Securitizations The majority of the Group’s securitization activities involve mortgages and mortgage-related securities and are predominantly transacted using SPEs. In a typical securitization, the SPE purchases assets financed by proceeds received from the SPE’s issuance of debt and equity instruments, certificates, CP and other notes of indebtedness. These assets and liabilities are recorded on the balance sheet of the SPE and not reflected on the Group’s consolidated balance sheet, unless either the Group sold the assets to the entity and the accounting requirements for sale were not met or the Group consolidates the SPE. The Group purchases commercial and residential mortgages for the purpose of securitization and sells these mortgage loans to SPEs. These SPEs issue commercial mortgage-backed securities (CMBS), residential mortgage-backed securities (RMBS) and ABS that are collateralized by the assets transferred to the SPE and that pay a return based on the returns on those assets. Investors in these mortgage-backed securities or ABS typically have recourse to the assets in the SPEs. Third-party guarantees may further enhance the creditworthiness of the assets. The investors and the SPEs have no recourse to the Group’s assets. The Group is typically an underwriter of, and makes a market in, these securities. The Group also transacts in re-securitizations of previously issued RMBS securities. Typically, certificates issued out of an existing securitization vehicle are sold into a newly created and separate securitization vehicle. Often, these re-securitizations are initiated in order to re-securitize an existing security to give the investor an investment with different risk ratings or characteristics. The Group also uses SPEs for other asset-backed financings relating to client-driven activity and for Group tax or regulatory purposes. Types of structures included in this category include managed collateralized loan obligations (CLOs), CLOs, leveraged finance, repack and other types of transactions, including life insurance structures, emerging market structures set up for financing, loan participation or loan origination purposes, and other alternative structures created for the purpose of investing in venture capital-like investments. CLOs are collateralized by loans transferred to the CLO vehicle and pay a return based on the returns on the loans. Leveraged finance structures are used to assist in the syndication of certain loans held by the Group, while repack structures are designed to give a client collateralized exposure to specific cash flows or credit risk backed by collateral purchased from the Group. In these asset-backed financing structures, investors typically only have recourse to the collateral of the SPE and do not have recourse to the Group’s assets. When the Group transfers assets into an SPE, it must assess whether that transfer is accounted for as a sale of the assets. Transfers of assets may not meet sale requirements if the assets have not been legally isolated from the Group and/or if the Group’s continuing involvement is deemed to give it effective control over the assets. If the transfer is not deemed a sale, it is instead accounted for as a secured borrowing, with the transferred assets as collateral. Gains and losses on securitization transactions depend, in part, on the carrying values of mortgages and loans involved in the transfer and are allocated between the assets sold and any beneficial interests retained according to the relative fair values at the date of sale. The Group does not retain material servicing responsibilities from securitization activities. The following table provides the gains or losses and proceeds from the transfer of assets relating to 2020, 2019 and 2018 securitizations of financial assets that qualify for sale accounting and subsequent derecognition, along with the cash flows between the Group and the SPEs used in any securitizations in which the Group still has continuing involvement, regardless of when the securitization occurred.

The gains or losses on the sale of the collateral is the difference between the fair value on the day prior to the securitization pricing date and the sale price of the loans. 2 Represents management fees and performance fees earned for investment management services provided to managed CLOs. Continuing involvement in transferred financial assets The Group may have continuing involvement in the financial assets that are transferred to an SPE, which may take several forms, including, but not limited to, servicing, recourse and guarantee arrangements, agreements to purchase or redeem transferred assets, derivative instruments, pledges of collateral and beneficial interests in the transferred assets. Beneficial interests, which are valued at fair value, include rights to receive all or portions of specified cash inflows received by an SPE, including, but not limited to, senior and subordinated shares of interest, principal, or other cash inflows to be “passed through” or “paid through”, premiums due to guarantors, CP obligations, and residual interests, whether in the form of debt or equity. The Group’s exposure resulting from continuing involvement in transferred financial assets is generally limited to beneficial interests typically held by the Group in the form of instruments issued by SPEs that are senior, subordinated or residual tranches. These instruments are held by the Group typically in connection with underwriting or market-making activities and are included in trading assets in the consolidated balance sheets. Any changes in the fair value of these beneficial interests are recognized in the consolidated statements of operations. Investors usually have recourse to the assets in the SPE and often benefit from other credit enhancements, such as collateral accounts, or from liquidity facilities, such as lines of credit or liquidity put option of asset purchase agreements. The SPE may also enter into a derivative contract in order to convert the yield or currency of the underlying assets to match the needs of the SPE investors, or to limit or change the credit risk of the SPE. The Group may be the provider of certain credit enhancements as well as the counterparty to any related derivative contract. The following table provides the outstanding principal balance of assets to which the Group continued to be exposed after the transfer of the financial assets to any SPE and the total assets of the SPE as of December 31, 2020 and 2019, regardless of when the transfer of assets occurred.

Fair value of beneficial interests The fair value measurement of the beneficial interests held at the time of transfer and as of the reporting date that result from any continuing involvement is determined using fair value estimation techniques, such as the present value of estimated future cash flows that incorporate assumptions that market participants customarily use in these valuation techniques. The fair value of the assets or liabilities that result from any continuing involvement does not include any benefits from financial instruments that the Group may utilize to hedge the inherent risks. Key economic assumptions at the time of transfer > Refer to “Fair value measurement” in Note 36 – Financial instruments for further information on the fair value hierarchy.

PSA utilizes the constant prepayment rate (CPR) assumptions. A 100% prepayment assumption assumes a prepayment rate of 0.2% per annum of the outstanding principal balance of mortgage loans in the first month. This increases by 0.2 percentage points thereafter during the term of the mortgage loan, leveling off to a CPR of 6% per annum beginning in the 30th month and each month thereafter during the term of the mortgage loan. 100 PSA equals 6 CPR. 2 To deter prepayment, commercial mortgage loans typically have prepayment protection in the form of prepayment lockouts and yield maintenances. 3 The rate is based on the weighted-average yield on the beneficial interests. 4 The range of expected credit losses only reflects instruments with an expected credit loss greater than zero unless all of the instruments have an expected credit loss of zero.

PSA utilizes the CPR assumptions. A 100% prepayment assumption assumes a prepayment rate of 0.2% per annum of the outstanding principal balance of mortgage loans in the first month. This increases by 0.2 percentage points thereafter during the term of the mortgage loan, leveling off to a CPR of 6% per annum beginning in the 30th month and each month thereafter during the term of the mortgage loan. 100 PSA equals 6 CPR. 4 The rate is based on the weighted-average yield on the beneficial interests. 5 The range of expected credit losses only reflects instruments with an expected credit loss greater than zero unless all of the instruments have an expected credit loss of zero. These sensitivities are hypothetical and do not reflect economic hedging activities. Changes in fair value based on a 10% or 20% variation in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, the effect of a variation in a particular assumption on the fair value of the beneficial interests is calculated without changing any other assumption. In practice, changes in one assumption may result in changes in other assumptions (for example, increases in market interest rates may result in lower prepayments and increased credit losses), which might magnify or counteract the sensitivities.

This provides an understanding of the nature and risks of short-term collateralized financing obtained through these types of transactions. Securities sold under repurchase agreements and securities lending transactions represent collateralized financing transactions used to earn net interest income, increase liquidity or facilitate trading activities. These transactions are collateralized principally by government debt securities, corporate debt securities, asset-backed securities, equity securities and other collateral and have terms ranging from on demand to a longer period of time. In the event of the Group’s default or a decline in fair value of collateral pledged, the repurchase agreement provides the counterparty with the right to liquidate the collateral held or request additional collateral. Similarly, in the event of the Group’s default, the securities lending transaction provides the counterparty the right to liquidate the securities borrowed. The following tables provide the gross obligation relating to securities sold under repurchase agreements, securities lending transactions and obligation to return securities received as collateral by the class of collateral pledged and by remaining contractual maturity as of December 31, 2020 and 2019.

Variable interest entities As a normal part of its business, the Group engages in various transactions that include entities that are considered VIEs and are grouped into three primary categories: collateralized debt obligations (CDOs)/CLOs, CP conduits and financial intermediation. VIEs are SPEs that typically either lack sufficient equity to finance their activities without additional subordinated financial support or are structured such that the holders of the voting rights do not substantively participate in the gains and losses of the entity. VIEs may be sponsored by the Group or third parties. Such entities are required to be assessed for consolidation, compelling the primary beneficiary to consolidate the VIE. The consolidation assessment requires an entity to determine whether it has the power to direct the activities that most significantly affect the economics of the VIE as well as whether the reporting entity has potentially significant benefits or losses in the VIE. The primary beneficiary assessment must be re-evaluated on an ongoing basis. Application of the requirements for consolidation of VIEs may require the exercise of significant judgment. In the event consolidation of a VIE is required, the exposure to the Group is limited to that portion of the VIE’s assets attributable to any variable interest held by the Group prior to any risk management activities to hedge the Group’s net exposure. Any interests held in the VIE by third parties, even though consolidated by the Group, will not typically impact its results of operations. Transactions with VIEs are generally executed to facilitate securitization activities or to meet specific client needs, such as providing liquidity or investing opportunities, and, as part of these activities, the Group may hold interests in the VIEs. Securitization-related transactions with VIEs involve selling or purchasing assets as well as possibly entering into related derivatives with those VIEs, providing liquidity, credit or other support. Other transactions with VIEs include derivative transactions in the Group’s capacity as the prime broker. The Group also enters into lending arrangements with VIEs for the purpose of financing projects or the acquisition of assets. Typically, the VIE’s assets are restricted in nature in that they are held primarily to satisfy the obligations of the entity. Further, the Group is involved with VIEs which were formed for the purpose of offering alternative investment solutions to clients. Such VIEs relate primarily to private equity investments, fund-linked vehicles or funds of funds, where the Group acts as structurer, manager, distributor, broker, market maker or liquidity provider. As a consequence of these activities, the Group holds variable interests in VIEs. Such variable interests consist of financial instruments issued by VIEs and which are held by the Group, certain derivatives with VIEs or loans to VIEs. Guarantees issued by the Group to or on behalf of VIEs may also qualify as variable interests. For such guarantees, including derivatives that act as guarantees, the notional amount of the respective guarantees is presented to represent the exposure. In general, investors in consolidated VIEs do not have recourse to the Group in the event of a default, except where a guarantee was provided to the investors or where the Group is the counterparty to a derivative transaction involving VIEs. Total assets of consolidated and non-consolidated VIEs for which the Group has involvement represent the total assets of the VIEs even though the Group’s involvement may be significantly less due to interests held by third-party investors. The asset balances for non-consolidated VIEs where the Group has significant involvement represent the most current information available to the Group regarding the remaining principal balance of assets owned. In most cases, the asset balances represent an amortized cost basis without regards to impairments in fair value, unless fair value information is readily available. The Group’s maximum exposure to loss is different from the carrying value of the assets of the VIE. This maximum exposure to loss consists of the carrying value of the Group variable interests held as trading assets, derivatives and loans, the notional amount of guarantees and off-balance sheet commitments to VIEs, rather than the amount of total assets of the VIEs. The maximum exposure to loss does not reflect the Group’s risk management activities, including effects from financial instruments that the Group may utilize to economically hedge the risks inherent in these VIEs. The economic risks associated with VIE exposures held by the Group, together with all relevant risk mitigation initiatives, are included in the Group’s risk management framework. The Group has not provided financial or other support to consolidated or non-consolidated VIEs that it was not contractually required to provide. Collateralized debt and loan obligations The Group engages in CDO/CLO transactions to meet client and investor needs, earn fees and sell financial assets and, for CLOs, loans. The Group may act as underwriter, placement agent or asset manager and may warehouse assets prior to the closing of a transaction. As part of its structured finance business, the Group purchases loans and other debt obligations from and on behalf of clients for the purpose of securitization. The loans and other debt obligations are sold to VIEs, which in turn issue CDO/CLOs to fund the purchase of assets such as investment grade and high yield corporate debt instruments. Typically, the collateral manager in a managed CDO/CLO is deemed to be the entity that has the power to direct the activities that most affect the economics of the entity. In a static CDO/CLO this “power” role is more difficult to analyze and may be the sponsor of the entity or the CDS counterparty. CDO/CLOs provide credit risk exposure to a portfolio of ABS or loans (cash CDO/CLOs) or a reference portfolio of securities or loans (synthetic CDO/CLOs). Cash CDO/CLO transactions hold actual securities or loans whereas synthetic CDO/CLO transactions use CDS to exchange the underlying credit risk instead of using cash assets. The Group may also act as a derivative counterparty to the VIEs, which are typically not variable interests, and may invest in portions of the notes or equity issued by the VIEs. The CDO/CLO entities may have actively managed portfolios or static portfolios. The securities issued by these VIEs are payable solely from the cash flows of the related collateral, and third-party creditors of these VIEs do not have recourse to the Group in the event of default. The Group’s exposure in CDO/CLO transactions is typically limited to interests retained in connection with its underwriting or market-making activities. Unless the Group has been deemed to have “power” over the entity and these interests are potentially significant, the Group is not the primary beneficiary of the vehicle and does not consolidate the entity. The Group’s maximum exposure to loss does not include any effects from financial instruments used to economically hedge the risks of the VIEs. Commercial paper conduit The Group acts as the administrator and provider of liquidity and credit enhancement facilities for Alpine Securitization Ltd (Alpine), a multi-seller asset-backed CP conduit used for client and Group financing purposes. Alpine discloses to CP investors certain portfolio and asset data and submits its portfolio to rating agencies for public ratings on its CP. This CP conduit purchases assets such as loans and receivables or enters into reverse repurchase agreements and finances such activities through the issuance of CP backed by these assets. In addition to CP, Alpine may also issue term notes with maturities up to 30 months. The Group (including Alpine) can enter into liquidity facilities with third-party entities pursuant to which it may be required to purchase assets from these entities to provide them with liquidity and credit support. The financing transactions are structured to provide credit support in the form of over-collateralization and other asset-specific enhancements. Alpine is a separate legal entity that is wholly owned by the Group. However, its assets are available to satisfy only the claims of its creditors. In addition, the Group, as administrator and liquidity facility provider, has significant exposure to and power over the activities of Alpine. Alpine is considered a VIE for accounting purposes and the Group is deemed the primary beneficiary and consolidates this entity. The overall average maturity of Alpine’s outstanding CP was approximately 209 days as of December 31, 2020. Alpine’s CP was rated A-1(sf) by Standard & Poor’s and P-1(sf) by Moody’s and had exposures mainly in reverse repurchase agreements with a Group entity, solar loans and leases, consumer loans, aircraft loans and leases and car loans and leases. The Group’s financial commitment to this CP conduit consists of obligations under liquidity agreements. The liquidity agreements are asset-specific arrangements, which require the Group to provide short-term financing to the CP conduit or to purchase assets from the CP conduit in certain circumstances, including, but not limited to, a lack of liquidity in the CP market such that the CP conduit cannot refinance its obligations or a default of an underlying asset. The asset-specific credit enhancements provided by the client seller of the assets remain unchanged as a result of such a purchase. In entering into such agreements, the Group reviews the credit risk associated with these transactions on the same basis that would apply to other extensions of credit. The Group enters into liquidity facilities with CP conduits administrated and sponsored by third parties. These third-party CP conduits are considered to be VIEs for accounting purposes. The Group is not the primary beneficiary and does not consolidate these third-party CP conduits. The Group’s financial commitment to these third-party CP conduits consists of obligations under liquidity agreements. The liquidity agreements are asset-specific arrangements, which require the Group to provide short-term financing to the third-party CP conduits or to purchase assets from these CP conduits in certain circumstances, including, but not limited to, a lack of liquidity in the CP market such that the CP conduits cannot refinance their obligations or a default of an underlying asset. The asset-specific credit enhancements, if any, provided by the client seller of the assets remain unchanged as a result of such a purchase. In entering into such agreements, the Group reviews the credit risk associated with these transactions on the same basis that would apply to other extensions of credit. In some situations, the Group can enter into liquidity facilities with these third-party CP conduits through Alpine. The Group’s economic risks associated with the Alpine CP conduit and the third-party CP conduits are included in the Group’s risk management framework including counterparty, economic risk capital and scenario analysis. Financial intermediation The Group has significant involvement with VIEs in its role as a financial intermediary on behalf of clients. The Group considers the likelihood of incurring a loss equal to the maximum exposure to be remote because of the Group’s risk mitigation efforts, including, but not limited to, economic hedging strategies and collateral arrangements. The Group’s economic risks associated with consolidated and non-consolidated VIE exposures arising from financial intermediation, together with all relevant risk mitigation initiatives, are included in the Group’s risk management framework. Financial intermediation consists of securitizations, funds, loans, and other vehicles. Securitizations Securitizations are primarily CMBS, RMBS and ABS vehicles. The Group acts as an underwriter, market maker, liquidity provider, derivative counterparty and/or provider of credit enhancements to VIEs related to certain securitization transactions. The maximum exposure to loss is the carrying value of the loan securities and derivative positions that are variable interests, if any, plus the exposure arising from any credit enhancements the Group provided. The Group’s maximum exposure to loss does not include any effects from financial instruments used to economically hedge the risks of the VIEs. The activities that have the most significant impact on the securitization vehicle are the decisions relating to defaulted loans, which are controlled by the servicer. The party that controls the servicing has the ability to make decisions that significantly affect the result of the activities of the securitization vehicle. If a securitization vehicle has multiple parties that control servicing over specific assets, the Group determines it has power when it has control over the servicing of greater than 50% of the assets in the securitization vehicle. When a servicer or its related party also has an economic interest that has the potential to absorb a significant portion of the gains and/or losses, it will be deemed the primary beneficiary and consolidate the vehicle. If the Group determines that it controls the relevant servicing, it then determines if it has the obligation to absorb losses from, or the right to receive benefits of, the securitization vehicle that could potentially be significant to the vehicle, primarily by evaluating the amount and nature of securities issued by the vehicle that it holds. Factors considered in this analysis include the level of subordination of the securities held as well as the size of the position, based on the percentage of the class of securities and

Fair value of beneficial interests The fair value measurement of beneficial interests held at the time of transfer and as of the reporting date that result from any continuing involvement is determined using fair value estimation techniques, such as the present value of estimated future cash flows that incorporate assumptions that market participants customarily use in these valuation techniques. The fair value of the assets or liabilities that result from any continuing involvement does not include any benefits from financial instruments that the Bank may utilize to hedge the inherent risks.

PSA utilizes the constant prepayment rate (CPR) assumptions. A 100% prepayment assumption assumes a prepayment rate of 0.2% per annum of the outstanding principal balance of mortgage loans in the first month. This increases by 0.2 percentage points thereafter during the term of the mortgage loan, leveling off to a CPR of 6% per annum beginning in the 30th month and each month thereafter during the term of the mortgage loan. 100 PSA equals 6 CPR. 2 To deter prepayment, commercial mortgage loans typically have prepayment protection in the form of prepayment lockouts and yield maintenances. 3 The rate was based on the weighted-average yield on the beneficial interests. 4 The range of expected credit losses only reflects instruments with an expected credit loss greater than zero unless all of the instruments have an expected credit loss of zero.

Commercial paper conduit The Bank acts as the administrator and provider of liquidity and credit enhancement facilities for Alpine Securitization Ltd (Alpine), a multi-seller asset-backed commercial paper (CP) conduit used for client and Bank financing purposes. Alpine discloses to CP investors certain portfolio and asset data and submits its portfolio to rating agencies for public ratings on its CP. This CP conduit purchases assets such as loans and receivables or enters into reverse repurchase agreements and finances such activities through the issuance of CP backed by these assets. In addition to CP, Alpine may also issue term notes with maturities up to 30 months. The Bank (including Alpine) can enter into liquidity facilities with third-party entities pursuant to which it may be required to purchase assets from these entities to provide them with liquidity and credit support. The financing transactions are structured to provide credit support in the form of over-collateralization and other asset-specific enhancements.

In addition, the Bank, as administrator and liquidity facility provider, has significant exposure to and power over the activities of Alpine. Alpine is considered a VIE for accounting purposes and the Bank is deemed the primary beneficiary and consolidates this entity. The overall average maturity of Alpine’s outstanding CP was approximately 209 days as of December 31, 2020. Alpine’s CP was rated A-1(sf) by Standard & Poor’s and P-1(sf) by Moody’s and had exposures mainly in reverse repurchase agreements with a Bank entity, solar loans and leases, consumer loans, aircraft loans and leases and car loans and leases. The Bank’s financial commitment to this CP conduit consists of obligations under liquidity agreements. The liquidity agreements are asset-specific arrangements, which require the Bank to provide short-term financing to the CP conduit or to purchase assets from the CP conduit in certain circumstances, including, but not limited to, a lack of liquidity in the CP market such that the CP conduit cannot refinance its obligations or a default of an underlying asset.

Financial instruments

Financial instruments	12 Months Ended
	Dec. 31, 2020
Financial instruments	36 Financial instruments The disclosure of the Group’s financial instruments below includes the following sections: ■ ■ ■ ■ Concentrations of credit risk Credit risk concentrations arise when a number of counterparties are engaged in similar business activities, are located in the same geographic region or when there are similar economic features that would cause their ability to meet contractual obligations to be similarly impacted by changes in economic conditions. The Group has in place a credit risk appetite framework which provides for the oversight and control of concentrations of credit exposures by single name, product, industry, and country. The Group Credit Portfolio Management function under the Global Chief Credit Officer is responsible for monitoring the portfolio and assessing compliance with the framework and the portfolio limits and controls in place. Credit risk concentrations are identified and measured using a range of quantitative tools and metrics and are reported to the Credit Risk Appetite Committee on a monthly basis. The Group Credit Portfolio Management function performs portfolio reviews and detailed analyses of selected segments of the portfolio which are presented to the Credit Risk Appetite Committee and to other governance forums including the Position & Client Risk cycle of Capital Allocation and Risk Management Committee and the Risk Committee where appropriate. From an industry point of view, the combined credit exposure of the Group is diversified. A substantial portion of the credit exposure is with individual clients, particularly through residential mortgages in Switzerland, corporate credit exposures and lombard lending arrangements, or relates to derivative and other financial transactions with financial institutions. In both cases, the customer base is extensive and the number and variety of transactions are broad. For transactions with financial institutions and corporations, the business is also geographically diverse, with operations focused in the Americas, Europe and, to a lesser extent, Asia Pacific. Fair value measurement A significant portion of the Group’s financial instruments is carried at fair value. Deterioration of financial markets could significantly impact the fair value of these financial instruments and the results of operations. The fair value of the majority of the Group’s financial instruments is based on quoted prices in active markets or observable inputs. These instruments include government and agency securities, certain short-term borrowings, most investment grade corporate debt, certain high yield debt securities, exchange-traded and certain OTC derivatives and most listed equity securities. In addition, the Group holds financial instruments for which no prices are available and which have few or no observable inputs. For these instruments, the determination of fair value requires subjective assessment and judgment, depending on liquidity, pricing assumptions, the current economic and competitive environment and the risks affecting the specific instrument. In such circumstances, valuation is determined based on management’s own judgments about the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk. These instruments include certain OTC derivatives, including interest rate, foreign exchange, equity and credit derivatives, certain corporate equity-linked securities, mortgage-related securities, private equity investments and certain loans and credit products, including leveraged finance, certain syndicated loans and certain high yield bonds, and life finance instruments. The fair value measurement disclosures exclude derivative transactions that are daily settled. The fair value of financial instruments is impacted by factors such as benchmark interest rates, prices of financial instruments issued by third parties, commodity prices, foreign exchange rates and index prices or rates. In addition, valuation adjustments are an integral part of the valuation process when market prices are not indicative of the credit quality of a counterparty, and are applied to both OTC derivatives and debt instruments. The impact of changes in a counterparty’s credit spreads (known as credit valuation adjustments) is considered when measuring the fair value of assets, and the impact of changes in the Group’s own credit spreads (known as debit valuation adjustments) is considered when measuring the fair value of its liabilities. For OTC derivatives, the impact of changes in both the Group’s and the counterparty’s credit standing is considered when measuring their fair value, based on current CDS prices. The adjustments also take into account contractual factors designed to reduce the Group’s credit exposure to a counterparty, such as collateral held and master netting agreements. For hybrid debt instruments with embedded derivative features, the impact of changes in the Group’s credit standing is considered when measuring their fair value, based on current funded debt spreads. US GAAP permits a reporting entity to measure the fair value of a group of financial assets and financial liabilities on the basis of the price that would be received to sell a net long position or paid to transfer a net short position for a particular risk exposure in an orderly transaction between market participants at the measurement date. As such, the Group continues to apply bid and offer adjustments to net portfolios of cash securities and/or derivative instruments to adjust the value of the net position from a mid-market price to the appropriate bid or offer level that would be realized under normal market conditions for the net long or net short position for a specific market risk. In addition, the Group reflects the net exposure to credit risk for its derivative instruments where the Group has legally enforceable agreements with its counterparties that mitigate credit risk exposure in the event of default. Valuation adjustments are recorded in a reasonable and consistent manner that results in an allocation to the relevant disclosures in the notes to the financial statements as if the valuation adjustment had been allocated to the individual unit of account. Fair value hierarchy The levels of the fair value hierarchy are defined as follows: ■ ■ : ■ The Group records net open positions at bid prices if long, or at ask prices if short, unless the Group is a market maker in such positions, in which case mid-pricing is utilized. Fair value measurements are not adjusted for transaction costs. Qualitative disclosures of valuation techniques Overview The Group has implemented and maintains a valuation control framework, which is supported by policies and procedures that define the principles for controlling the valuation of the Group’s financial instruments. Control functions such as Product Control and Risk Management review and approve significant valuation policies and procedures. The framework includes three main internal processes: (i) valuation governance; (ii) independent price verification and significant unobservable inputs review; and (iii) a cross-functional pricing model review. Through this framework, the Group determines the reasonableness of the fair value of its financial instruments. On a monthly basis, meetings are held for each business line with senior representatives of the Front Office and Product Control to discuss independent price verification results, valuation adjustments, and other significant valuation issues. On a quarterly basis, a review of significant changes in the fair value of financial instruments is undertaken by Product Control and conclusions are reached regarding the reasonableness of those changes. Additionally, on a quarterly basis, meetings are held for each business line with senior representatives of the Front Office and control functions such as Product Control and Risk Management to discuss independent price verification results, valuation issues, business and market updates, as well as a review of significant changes in fair value from the prior quarter, significant unobservable inputs and prices used in valuation techniques, and valuation adjustments. The valuation results are aggregated for reporting to the Valuation Risk Management Committee (VARMC) and the Audit Committee. The VARMC, which is comprised of Executive Board members and the heads of the business and control functions, meets to review and ratify valuation review conclusions, and to resolve significant valuation issues for the Group. Oversight of the valuation control framework is through specific and regular reporting on valuation directly to the Group’s Executive Board through the VARMC. One of the key components of the governance process is the segregation of duties between the Front Office and Product Control. The Front Office is responsible for measuring inventory at fair value on a daily basis, while Product Control is responsible for independently reviewing and validating those valuations on a periodic basis. The Front Office values the inventory using, wherever possible, observable market data which may include executed transactions, dealer quotes or broker quotes for the same or similar instruments. Product Control validates this inventory using independently sourced data that also includes executed transactions, dealer quotes, and broker quotes. In general, Product Control utilizes independent pricing service data as part of its review process. Independent pricing service data is analyzed to ensure that it is representative of fair value, including confirming that the data corresponds to executed transactions or executable broker quotes, review and assessment of contributors to ensure they are active market participants, review of statistical data and utilization of pricing challenges. The analysis also includes understanding the sources of the pricing service data and any models or assumptions used in determining the results. The purpose of the review is to judge the quality and reliability of the data for fair value measurement purposes and its appropriate level of usage within the Product Control independent valuation review. For certain financial instruments the fair value is estimated in full or in part using valuation techniques based on assumptions that are not supported by market observable prices, rates or other inputs. In addition, there may be uncertainty about a valuation resulting from the choice of valuation technique or model used, the assumptions embedded in those models, the extent to which inputs are not market observable, or as a consequence of other elements affecting the valuation technique or model. Model calibration is performed when significant new market information becomes available or at a minimum on a quarterly basis as part of the business review of significant unobservable inputs for level 3 instruments. For models that have been deemed to be significant to the overall fair value of the financial instrument, model validation is performed as part of the periodic review of the related model. The following information on the valuation techniques and significant unobservable inputs of the various financial instruments and the section “Uncertainty of fair value measurements at the reporting date from the use of significant unobservable inputs” should be read in conjunction with the tables “Assets and liabilities measured at fair value on a recurring basis”, “Quantitative information about level 3 assets measured at fair value on a recurring basis” and “Quantitative information about level 3 liabilities measured at fair value on a recurring basis”. Central bank funds sold, securities purchased under resale agreements and securities borrowing transactions Securities purchased under resale agreements and securities sold under repurchase agreements are measured at fair value using discounted cash flow analysis. Future cash flows are discounted using observable market interest rate repurchase/resale curves for the applicable maturity and underlying collateral of the instruments. As such, the significant majority of both securities purchased under resale agreements and securities sold under repurchase agreements are included in level 2 of the fair value hierarchy. Structured resale and repurchase agreements include embedded derivatives, which are measured using the same techniques as described below for stand-alone derivative contracts held for trading purposes or used in hedge accounting relationships. If the value of the embedded derivative is determined using significant unobservable inputs, those structured resale and repurchase agreements included are classified as level 3 in the fair value hierarchy. The significant unobservable input is funding spread. Securities purchased under resale agreements are usually fully collateralized or over-collateralized by government securities, money market instruments, corporate bonds, or other debt instruments. In the event of counterparty default, the collateral service agreement provides the Group with the right to liquidate the collateral held. Debt securities Foreign governments Foreign government debt securities typically have quoted prices in active markets and are mainly categorized as level 1 instruments. Valuations of foreign government debt securities for which market prices are not available are based on yields reflecting credit rating, historical performance, delinquencies, loss severity, the maturity of the security, recent transactions in the market or other modeling techniques, which may involve judgment. Those securities where the price or model inputs are observable in the market are categorized as level 2 instruments, while those securities where prices are not observable and significant model inputs are unobservable are categorized as level 3 of the fair value hierarchy. Corporates Corporate bonds are priced to reflect current market levels either through recent market transactions or broker or dealer quotes. Where a market price for the particular security is not directly available, valuations are obtained based on yields reflected by other instruments in the specific or similar entity’s capital structure and adjusting for differences in seniority and maturity, benchmarking to a comparable security where market data is available (taking into consideration differences in credit, liquidity and maturity), or through the application of cash flow modeling techniques utilizing observable inputs, such as current interest rate curves and observable CDS spreads. Significant unobservable inputs may include correlation and price. For securities using market comparable price, the differentiation between level 2 and level 3 is based upon the relative significance of any yield adjustments as well as the accuracy of the comparison characteristics (i.e., the observable comparable security may be in the same country but a different industry and may have a different seniority level – the lower the comparability the more likely the security will be level 3). RMBS, CMBS and CDO securities Fair values of RMBS, CMBS and CDO may be available through quoted prices, which are often based on the prices at which similarly structured and collateralized securities trade between dealers and to and from customers. Fair values of RMBS, CMBS and CDO for which there are significant unobservable inputs are valued using capitalization rate and discount rate. Price may not be observable for fair value measurement purposes for many reasons, such as the length of time since the last executed transaction for the related security, use of a price from a similar instrument, or use of a price from an indicative quote. Fair values determined by market comparable price may include discounted cash flow models using the inputs credit spread, default rate, discount rate, prepayment rate and loss severity. Prices from similar observable instruments are used to calculate implied inputs which are then used to value unobservable instruments using discounted cash flow. The discounted cash flow price is then compared to the unobservable prices and assessed for reasonableness. For most structured debt securities, determination of fair value requires subjective assessment depending on liquidity, ownership concentration, and the current economic and competitive environment. Valuation is determined based on the Front Office’s own assumptions about how market participants would price the asset. Collateralized bond and loan obligations are split into various structured tranches and each tranche is valued based upon its individual rating and the underlying collateral supporting the structure. Valuation models are used to value both cash and synthetic CDOs. Equity securities The majority of the Group’s positions in equity securities are traded on public stock exchanges for which quoted prices are readily and regularly available and are therefore categorized as level 1 instruments. Level 2 and level 3 equities include fund-linked products, convertible bonds or equity securities with restrictions that are not traded in active markets. Significant unobservable inputs may include earnings before interest, taxes, depreciation and amortization (EBITDA) multiple and market comparable price. Derivatives Derivatives held for trading purposes or used in hedge accounting relationships include both OTC and exchange-traded derivatives. The fair values of exchange-traded derivatives measured using observable exchange prices are included in level 1 of the fair value hierarchy. For exchange-traded derivatives where the volume of trading is low, the observable exchange prices may not be considered executable at the reporting date. These derivatives are valued in the same manner as similar observable OTC derivatives and are included in level 2 of the fair value hierarchy. If the similar OTC derivative used for valuing the exchange-traded derivative is not observable, the exchange-traded derivative is included in level 3 of the fair value hierarchy. The fair values of OTC derivatives are determined on the basis of either industry standard models or internally developed proprietary models. Both model types use various observable and unobservable inputs in order to determine fair value. The inputs include those characteristics of the derivative that have a bearing on the economics of the instrument. The determination of the fair value of many derivatives involves only a limited degree of subjectivity because the required inputs are observable in the marketplace, while more complex derivatives may use unobservable inputs that rely on specific proprietary modeling assumptions. Where observable inputs (prices from exchanges, dealers, brokers or market consensus data providers) are not available, attempts are made to infer values from observable prices through model calibration (spot and forward rates, mean reversion, benchmark interest rate curves and volatility inputs for commonly traded option products). For inputs that cannot be derived from other sources, estimates from historical data may be made. OTC derivatives where the majority of the value is derived from market observable inputs are categorized as level 2 instruments, while those where the majority of the value is derived from unobservable inputs are categorized as level 3 of the fair value hierarchy. The valuation of derivatives includes an adjustment for the cost of funding uncollateralized OTC derivatives. Interest rate derivatives OTC vanilla interest rate products, such as interest rate swaps, swaptions and caps and floors are valued by discounting the anticipated future cash flows. The future cash flows and discounting are derived from market standard yield curves and industry standard volatility inputs. Where applicable, exchange-traded prices are also used to value exchange-traded futures and options and can be used in yield curve construction. For more complex products, inputs include, but are not limited to basis spread, correlation, credit spread, prepayment rate and volatility skew. Foreign exchange derivatives Foreign exchange derivatives include vanilla products such as spot, forward and option contracts where the anticipated discounted future cash flows are determined from foreign exchange forward curves and industry standard optionality modeling techniques. Where applicable, exchange-traded prices are also used for futures and option prices. For more complex products inputs include, but are not limited to, contingent probability, correlation and prepayment rate. Equity and index-related derivatives Equity derivatives include a variety of products ranging from vanilla options and swaps to exotic structures with bespoke payoff profiles. The main inputs in the valuation of equity derivatives may include buyback probability, correlation, gap risk, price and volatility. Generally, the interrelationship between the correlation and volatility is positively correlated. Credit derivatives Credit derivatives include index, single-name and multi-name CDS in addition to more complex structured credit products. Vanilla products are valued using industry standard models and inputs that are generally market observable including credit spread and recovery rate. Complex structured credit derivatives are valued using proprietary models requiring inputs such as correlation, credit spread, funding spread, loss severity, prepayment rate and recovery rate. These inputs are generally implied from available market observable data. Other trading assets Other trading assets primarily include life settlement and premium finance instruments and RMBS loans. Life settlement and premium finance instruments are valued using proprietary models with several inputs. The significant unobservable inputs of the fair value for life settlement and premium finance instruments is the estimate of market implied life expectancy, while for RMBS loans it is market comparable price. For life settlement and premium finance instruments, individual life expectancy rates are typically obtained by multiplying a base mortality curve for the general insured population provided by a professional actuarial organization together with an individual-specific multiplier. Individual-specific multipliers are determined based on data from third-party life expectancy data providers, which examine the insured individual’s medical conditions, family history and other factors to arrive at a life expectancy estimate. For RMBS loans, the use of market comparable price varies depending upon each specific loan. For some loans, similar to unobservable RMBS securities, prices from similar observable instruments are used to calculate implied inputs which are then used to value unobservable instruments using discounted cash flow. The discounted cash flow price is then compared to the unobservable prices and assessed for reasonableness. For other RMBS loans, the loans are categorized by specific characteristics, such as loan-to-value ratio, average account balance, loan type (single or multi-family), lien, seasoning, coupon, FICO score, locality, delinquency status, cash flow velocity, roll rates, loan purpose, occupancy, servicers advance agreement type, modification status, Federal Housing Administration insurance, property value and documentation quality. Loans with unobservable prices are put into consistent buckets which are then compared to market observable comparable prices in order to assess the reasonableness of those unobservable prices. Other investments Private equity funds, hedge funds and equity method investment funds Equity method investment funds principally include equity investments in the form of a) direct investments in third-party hedge funds, private equity funds and funds of funds, b) equity method investments where the Group has the ability to significantly influence the operating and financial policies of the investee, and c) direct investments in non-marketable equity securities. Direct investments in third-party hedge funds, private equity funds and funds of funds are measured at fair value based on their published NAVs as permitted by ASC Topic 820 – Fair Value Measurement. In some cases, NAVs may be adjusted where there is sufficient evidence that the NAV published by the investment manager is not in line with the fund’s observable market data, it is probable that the investment will be sold for an amount other than NAV or other circumstances exist that would require an adjustment to the published NAV. Although rarely adjusted, significant judgment is involved in making any adjustments to the published NAVs. The investments for which the fair value is measured using the NAV practical expedient are not categorized within the fair value hierarchy. Direct investments in non-marketable equity securities consist of both real estate investments and non-real estate investments. Equity-method investments and direct investments in non-marketable equity securities are initially measured at their transaction price, as this is the best estimate of fair value. Thereafter, these investments are individually measured at fair value based upon a number of factors that include any recent rounds of financing involving third-party investors, comparable company transactions, multiple analyses of cash flows or book values, or discounted cash flow analyses. The availability of information used in these modeling techniques is often limited and involves significant judgment in evaluating these different factors over time. As a result, these investments are included in level 3 of the fair value hierarchy. Life finance instruments Life finance instruments include single premium immediate annuities (SPIA) and other premium finance instruments. Life finance instruments are valued in a similar manner as described for life settlement and premium finance instruments under the other trading assets section above. Loans The Group’s loan portfolio which is measured at fair value primarily consists of commercial and industrial loans and loans to financial institutions. Within these categories, loans measured at fair value include commercial loans, real estate loans, corporate loans, leverage finance loans and emerging market loans. Fair value is based on recent transactions and quoted prices, where available. Where recent transactions and quoted prices are not available, fair value may be determined by relative value benchmarking (which includes pricing based upon another position in the same capital structure, other comparable loan issues, generic industry credit spreads, implied credit spreads derived from CDS for the specific borrower, and enterprise valuations) or calculated based on the exit price of the collateral, based on current market conditions. Both the funded and unfunded portion of revolving credit lines on the corporate lending portfolio are valued using a loan pricing model, which requires estimates of significant inputs including credit conversion factors, credit spreads, recovery rates and weighted average life of the loan. Significant unobservable inputs may include credit spread and price. The Group’s other assets and liabilities include mortgage loans held in conjunction with securitization activities and assets and liabilities of VIEs and mortgage securitizations that do not meet the criteria for sale treatment under US GAAP. The fair value of mortgage loans held in conjunction with securitization activities is determined on a whole-loan basis and is consistent with the valuation of RMBS loans discussed in “Other trading assets” above. Whole-loan valuations are calculated based on the exit price reflecting the current market conditions. The fair value of assets and liabilities of VIEs and mortgage securitizations that do not meet the criteria for sale treatment under US GAAP are determined based on the quoted prices for securitized bonds, where available, or on cash flow analyses for securitized bonds, when quoted prices are not available. The fair value of the consolidated financial assets of RMBS and CMBS securitization vehicles, which qualify as collateralized financing entities, are measured on the basis of the more observable fair value of the VIEs’ financial liabilities. Short-term borrowings and long-term debt The Group’s short-term borrowings and long-term debt include structured notes (hybrid financial instruments that are both bifurcatable and non-bifurcatable) and vanilla debt. The fair value of structured notes is based on quoted prices, where available. When quoted prices are not available, fair value is determined by using a discounted cash flow model incorporating the Group’s credit spreads, the value of derivatives embedded in the debt and the residual term of the issuance based on call options. Derivatives structured into the issued debt are valued consistently with the Group’s stand-alone derivative contracts held for trading purposes or used in hedge accounting relationships as discussed above. The fair value of structured debt is heavily influenced by the combined call options and performance of the underlying derivative returns. Significant unobservable inputs for short-term borrowings and long-term debt include buyback probability, correlation, credit spread, gap risk, mean reversion, price, recovery rate and volatility. Generally, the interrelationships between correlation, credit spread, gap risk and volatility inputs are positively correlated. Other liabilities Failed sales These liabilities represent the financing of assets that did not achieve sale accounting treatment under US GAAP. Failed sales are valued in a manner consistent with the related underlying financial instruments.

Capital adequacy

Capital adequacy	12 Months Ended
	Dec. 31, 2020
Capital adequacy	38 Capital adequacy The Group is subject to the Basel III framework, as implemented in Switzerland, as well as Swiss legislation and regulations for systemically important banks (Swiss Requirements), which include capital, liquidity, leverage and large exposure requirements and rules for emergency plans designed to maintain systemically relevant functions in the event of threatened insolvency. The legislation implementing the Basel III framework in Switzerland in respect of capital requirements for systemically relevant banks, including the Group, goes beyond the Basel III minimum standards for systemically relevant banks. The Swiss TLAC standards were phased in from 2016 through 2019 and became fully effective on January 1, 2020. The Group, which is subject to regulation by FINMA, has based its capital adequacy calculations on US GAAP financial statements, as permitted by FINMA Circular 2013/1. Under the Capital Adequacy Ordinance, Swiss banks classified as systemically important banks operating internationally, such as the Group, are subject to two different minimum requirements for loss-absorbing capacity: such banks must hold sufficient capital that absorbs losses to ensure continuity of service (going concern requirement), and they must issue sufficient debt instruments to fund an orderly resolution without recourse to public resources (gone concern requirement). Going concern capital and gone concern capital together form the Group’s total loss-absorbing capacity. The going concern and gone concern requirements are generally aligned with the Financial Stability Board’s total loss-absorbing capacity standard. Both the going concern and the gone concern requirements were subject to phase-in, with gradually increasing requirements as well as grandfathering provisions for certain outstanding instruments, and became fully effective on January 1, 2020. Under the Capital Adequacy Ordinance’s grandfathering provisions, additional tier 1 capital instruments with a low trigger qualify as going concern capital until their first call date; additional tier 1 capital instruments and tier 2 capital instruments that no longer qualify as going concern capital, qualify as gone concern capital until termination or one year before their final maturity, respectively. Additionally, there are FINMA decrees that apply to the Group as a systemically important bank operating internationally, including capital adequacy requirements as well as liquidity and risk diversification requirements. Banks that do not maintain the minimum requirements may be limited in their ability to pay dividends and make discretionary bonus payments and other earnings distributions. The Group’s balance sheet positions and off-balance sheet exposures translate into risk-weighted assets, which are categorized as credit, market and operational risk-weighted assets. When assessing risk-weighted assets, it is not the nominal size, but rather the nature (including risk mitigation such as collateral or hedges) of the balance sheet positions or off-balance sheet exposures that determines the risk-weighted assets. Leverage exposure consists of period-end total assets and prescribed regulatory adjustments, such as derivative financial instruments, securities financing transactions and off-balance sheet exposures. Capital ratios measure the Group’s capital components against risk-weighted assets and leverage ratios measure them against the end-of-period leverage exposure. As of December 31, 2020 and 2019, the Group’s capital position exceeded its capital requirements under the regulatory provisions outlined under Swiss Requirements. Broker-dealer operations Certain of the Group’s broker-dealer subsidiaries are also subject to capital adequacy requirements. As of December 31, 2020 and 2019, the Group and its subsidiaries complied with all applicable regulatory capital adequacy requirements. Dividend restrictions Certain of the Group’s subsidiaries are subject to legal restrictions governing the amount of dividends they can pay (for example, pursuant to corporate law as defined by the Swiss Code of Obligations). Under the Swiss Code of Obligations, dividends may be paid out only if and to the extent the corporation has distributable profits from previous business years, or if the free reserves of the corporation are sufficient to allow distribution of a dividend. In addition, at least 5% of the annual net profits must be retained and booked as general legal reserves for so long as these reserves amount to less than 20% of the paid-in share capital. The reserves currently exceed this 20% threshold. Furthermore, dividends may be paid out only after shareholder approval at the Annual General Meeting. As of December 31, 2020 and 2019, Credit Suisse Group AG was not subject to restrictions on its ability to pay the proposed dividends.

Assets under management

Assets under management	39 Assets under management The following disclosure provides information regarding client assets, assets under management and net new assets as regulated by FINMA. Assets under management Assets under management include assets for which the Group provides investment advisory or discretionary asset management services, investment fund assets and assets invested in other investment fund-like pooled investment vehicles managed by the Group. The classification of assets under management is conditional upon the nature of the services provided by the Group and the clients’ intentions. Assets are individually assessed on the basis of each client’s intentions and objectives and the nature of the banking services provided to that client. In order to be classified as assets under management, the Group must currently or in the foreseeable future expect to provide a service where the involvement of the Group’s banking or investment expertise (e.g. as asset manager or investment advisor) is not purely executional or custodial in nature. Assets under custody are client assets held mainly for execution-related or safekeeping/custody purposes only and therefore are not considered assets under management since the Group does not generally provide asset allocation or financial advice. Assets of corporate clients and public institutions that are used primarily for cash management or transaction executional purposes for which no investment advice is provided are classified as commercial assets or assets under custody and therefore do not qualify as assets under management. For the purpose of classifying assets under management, clients with multiple accounts are assessed from an overall relationship perspective. Accounts that are clearly separate from the remainder of the client relationship and represent assets held for custody purposes only are not included as assets under management. The initial classification of the assets may not be permanent as the nature of the client relationship is reassessed on an on-going basis. If changes in client intent or activity warrant reclassification between client asset categories, the required reclassification adjustments are made immediately when the change in intent or activity occurs. Reclassifications between assets under management and assets held for transaction-related or custodial purposes result in corresponding net asset inflows or outflows. A portion of the Group’s assets under management results from double counting. Double counting arises when assets under management are subject to more than one level of asset management services. Each separate advisory or discretionary service provides additional benefits to the client and represents additional income for the Group. Specifically, double counting primarily results from the investment of assets under management in collective investment instruments managed by the Group. The extent of double counting is disclosed in the following table. Assets under management end of 2020 2019 CHF billion Assets in collective investment instruments managed by Credit Suisse 215.6 212.2 Assets with discretionary mandates 267.4 277.5 Other assets under management 1,028.9 1,017.5 Assets under management (including double counting) 1,511.9 1,507.2 of which double counting 49.1 51.0 Changes in assets under management 2020 2019 Assets under management (CHF billion) Balance at beginning of period 1 1,507.2 1,344.9 Net new assets/(net asset outflows) 42.0 79.3 Market movements, interest, dividends and foreign exchange (14.7) 106.8 of which market movements, interest and dividends 2 53.4 126.6 of which foreign exchange (68.1) (19.8) Other effects (22.6) (23.8) Balance at end of period 1,511.9 1,507.2 1 Including double counting. 2 Net of commissions and other expenses and net of interest expenses charged. Net new assets Net new assets measure the degree of success in acquiring assets under management or changes in assets under management through warranted reclassifications. The calculation is based on the direct method, taking into account individual cash payments, security deliveries and cash flows resulting from loan increases or repayments. Interest and dividend income credited to clients and commissions, interest and fees charged for banking services as well as changes in assets under management due to currency and market volatility are not taken into account when calculating net new assets, as such charges or market movements are not directly related to the Group’s success in acquiring assets under management. Similarly other effects mainly relate to asset inflows and outflows due to acquisition or divestiture, exit from businesses or markets or exits due to new regulatory requirements and are not taken into account when calculating net new assets. The Group reviews relevant policies regarding client assets on a regular basis. Divisional allocation Assets under management and net new assets for the Private Clients business in Swiss Universal Bank, the Private Banking business in International Wealth Management, Asia Pacific and the Corporate & Institutional Banking business in Swiss Universal Bank are allocated based on the management areas (business areas) that effectively manage the assets. The distribution of net new assets resulting from internal referral arrangements is governed under the net new asset referral framework, which includes preset percentages for the allocation of net new assets to the businesses. The allocation of assets under management and net new assets for Asset Management in the Internal Wealth Management division reflects the location where the investment vehicles are managed and where the costs of managing the funds are incurred.

Litigation

Litigation	12 Months Ended
	Dec. 31, 2020
Litigation	40 Litigation The Group is involved in a number of judicial, regulatory and arbitration proceedings concerning matters arising in connection with the conduct of its businesses, including those disclosed below. Some of these proceedings have been brought on behalf of various classes of claimants and seek damages of material and/or indeterminate amounts. The Group accrues loss contingency litigation provisions and takes a charge to income in connection with certain proceedings when losses, additional losses or ranges of loss are probable and reasonably estimable. The Group also accrues litigation provisions for the estimated fees and expenses of external lawyers and other service providers in relation to such proceedings, including in cases for which it has not accrued a loss contingency provision. The Group accrues these fee and expense litigation provisions and takes a charge to income in connection therewith when such fees and expenses are probable and reasonably estimable. The Group reviews its legal proceedings each quarter to determine the adequacy of its litigation provisions and may increase or release provisions based on management’s judgment and the advice of counsel. The establishment of additional provisions or releases of litigation provisions may be necessary in the future as developments in such proceedings warrant. The specific matters described below include (a) proceedings where the Group has accrued a loss contingency provision, given that it is probable that a loss may be incurred and such loss is reasonably estimable; and (b) proceedings where the Group has not accrued such a loss contingency provision for various reasons, including, but not limited to, the fact that any related losses are not reasonably estimable. The description of certain of the matters below includes a statement that the Group has established a loss contingency provision and discloses the amount of such provision; for the other matters no such statement is made. With respect to the matters for which no such statement is made, either (a) the Group has not established a loss contingency provision, in which case the matter is treated as a contingent liability under the applicable accounting standard, or (b) the Group has established such a provision but believes that disclosure of that fact would violate confidentiality obligations to which the Group is subject or otherwise compromise attorney-client privilege, work product protection or other protections against disclosure or compromise the Group’s management of the matter. The future outflow of funds in respect of any matter for which the Group has accrued loss contingency provisions cannot be determined with certainty based on currently available information, and accordingly may ultimately prove to be substantially greater (or may be less) than the provision that is reflected on the Group’s balance sheet. It is inherently difficult to determine whether a loss is probable or even reasonably possible or to estimate the amount of any loss or loss range for many of the Group’s legal proceedings. Estimates, by their nature, are based on judgment and currently available information and involve a variety of factors, including, but not limited to, the type and nature of the proceeding, the progress of the matter, the advice of counsel, the Group’s defenses and its experience in similar matters, as well as its assessment of matters, including settlements, involving other defendants in similar or related cases or proceedings. Factual and legal determinations, many of which are complex, must be made before a loss, additional losses or ranges of loss can be reasonably estimated for any proceeding. Most matters pending against the Group seek damages of an indeterminate amount. While certain matters specify the damages claimed, such claimed amount may not represent the Group’s reasonably possible losses. For certain of the proceedings discussed below the Group has disclosed the amount of damages claimed and certain other quantifiable information that is publicly available. The following table presents a roll forward of the Group’s aggregate litigation provisions. Litigation provisions 2020 CHF million Balance at beginning of period 898 Increase in litigation accruals 1,358 Decrease in litigation accruals (131) Decrease for settlements and other cash payments (391) Foreign exchange translation (74) Balance at end of period 1,660 The Group’s aggregate litigation provisions include estimates of losses, additional losses or ranges of loss for proceedings for which such losses are probable and can be reasonably estimated. The Group does not believe that it can estimate an aggregate range of reasonably possible losses for certain of its proceedings because of their complexity, the novelty of some of the claims, the early stage of the proceedings, the limited amount of discovery that has occurred and/or other factors. The Group’s estimate of the aggregate range of reasonably possible losses that are not covered by existing provisions for the proceedings discussed below for which the Group believes an estimate is possible is zero to CHF 0.9 billion. After taking into account its litigation provisions, the Group believes, based on currently available information and advice of counsel, that the results of its legal proceedings, in the aggregate, will not have a material adverse effect on the Group’s financial condition. However, in light of the inherent uncertainties of such proceedings, including those brought by regulators or other governmental authorities, the ultimate cost to the Group of resolving such proceedings may exceed current litigation provisions and any excess may be material to its operating results for any particular period, depending, in part, upon the operating results for such period. Mortgage-related matters Government and regulatory related matters Various financial institutions, including Credit Suisse Securities (USA) LLC (CSS LLC) and certain of its affiliates, have received requests for information from, and/or have been defending civil actions by, certain regulators and/or government entities, including the US Department of Justice (DOJ) and other members of the Residential Mortgage-Backed Securities (RMBS) Working Group of the US Financial Fraud Enforcement Task Force, regarding the origination, purchase, securitization, servicing and trading of subprime and non-subprime residential and commercial mortgages and related issues. CSS LLC and its affiliates are cooperating with such requests for information. DOJ RMBS settlement As previously disclosed, on January 18, 2017, CSS LLC and its current and former US subsidiaries and US affiliates reached a settlement with the DOJ related to its legacy RMBS business, a business conducted through 2007. The settlement resolved potential civil claims by the DOJ related to certain of those Credit Suisse entities’ packaging, marketing, structuring, arrangement, underwriting, issuance and sale of RMBS. Pursuant to the terms of the settlement a civil monetary penalty was paid to the DOJ in January 2017. The settlement also required the above-mentioned entities to provide a specified amount of consumer relief measures, including affordable housing payments and loan forgiveness, within five years of the settlement, and the DOJ and Credit Suisse agreed to the appointment of an independent monitor to oversee the completion of the consumer relief requirements of the settlement. The monitor has published reports periodically noting Credit Suisse’s cooperation and progress toward satisfaction of the consumer relief requirements. NJAG litigation On December 18, 2013, the New Jersey Attorney General (NJAG), on behalf of the State of New Jersey, filed a civil action in the Superior Court of New Jersey, Chancery Division, Mercer County (SCNJ), against CSS LLC and affiliated entities in their roles as issuer, sponsor, depositor and/or underwriter of RMBS transactions prior to 2008. The original complaint, which referenced 13 RMBS issued, sponsored, deposited and underwritten by CSS LLC and its affiliates in 2006 and 2007, alleges that CSS LLC and its affiliates misled investors and engaged in fraud or deceit in connection with the offer and sale of RMBS, and seeks an unspecified amount of damages. On August 21, 2014, the SCNJ dismissed without prejudice the action brought against CSS LLC and its affiliates by the NJAG. On September 4, 2014, the NJAG filed an amended complaint against CSS LLC and its affiliates, asserting additional allegations but not expanding the number of claims or RMBS referenced in the original complaint. On August 21, 2019, the NJAG filed a motion for partial summary judgment. On November 18, 2019, CSS LLC and its affiliates filed a cross-motion for partial summary judgment. Civil litigation CSS LLC and/or certain of its affiliates have also been named as defendants in various civil litigation matters related to their roles as issuer, sponsor, depositor, underwriter and/or servicer of RMBS transactions. These cases include or have included class action lawsuits, actions by individual investors in RMBS, actions by monoline insurance companies that guaranteed payments of principal and interest for certain RMBS, and repurchase actions by RMBS trusts, trustees and/or investors. Although the allegations vary by lawsuit, plaintiffs in the class actions and individual investor actions generally allege that the offering documents of securities issued by various RMBS securitization trusts contained material misrepresentations and omissions, including statements regarding the underwriting standards pursuant to which the underlying mortgage loans were issued; monoline insurers generally allege that loans that collateralize RMBS they insured breached representations and warranties made with respect to the loans at the time of securitization and that they were fraudulently induced to enter into the transactions; and repurchase action plaintiffs generally allege breached representations and warranties in respect of mortgage loans and failure to repurchase such mortgage loans as required under the applicable agreements. The amounts disclosed below do not reflect actual realized plaintiff losses to date or anticipated future litigation exposure. Rather, unless otherwise stated, these amounts reflect the original unpaid principal balance amounts as alleged in these actions and do not include any reduction in principal amounts since issuance. Further, unless otherwise stated, amounts attributable to an “operative pleading” for the individual investor actions are not altered for settlements, dismissals or other occurrences, if any, that may have caused the amounts to change subsequent to the operative pleading. In addition to the mortgage-related actions discussed below, a number of other entities have threatened to assert claims against CSS LLC and/or its affiliates in connection with various RMBS issuances. Individual investor actions CSS LLC and, in one instance, its affiliates, as an RMBS issuer, underwriter and/or other participant, along with other defendants, have been named as defendants in: (i) one action brought by the Federal Deposit Insurance Corporation (FDIC), as receiver for Citizens National Bank and Strategic Capital Bank, in the US District Court for the Southern District of New York (SDNY), in which claims against CSS LLC and its affiliates relate to approximately USD 28 million of the RMBS at issue (approximately 20% 23% CSS LLC and certain of its affiliates are the only defendants named in an action brought by IKB Deutsche Industriebank AG and affiliated entities in the Supreme Court for the State of New York, New York County (SCNY), in which claims against CSS LLC and its affiliates relate to approximately USD 97 million of RMBS at issue; this action is at an intermediate procedural stage. As disclosed in Credit Suisse’s second quarter Financial Report of 2020, on July 16, 2020, following a settlement, the Washington state court presiding in an investor action brought by the Federal Home Loan Bank of Seattle dismissed with prejudice all claims against CSS LLC and its affiliates relating to approximately USD 145 million of RMBS at issue. On December 8, 2020, following a settlement, the Massachusetts state court presiding in an investor action brought by the Federal Home Loan Bank of Boston dismissed with prejudice all claims against CSS LLC and its affiliates relating to approximately USD 333 million of RMBS at issue. Monoline insurer disputes CSS LLC and certain of its affiliates are defendants in one monoline insurer action pending in the SCNY, commenced by MBIA Insurance Corp. (MBIA) as guarantor for payments of principal and interest related to approximately USD 770 million of RMBS issued in an offering sponsored by the Credit Suisse defendants. One theory of liability advanced by MBIA is that an affiliate of CSS LLC must repurchase certain mortgage loans from the trusts at issue. MBIA claims that the vast majority of the underlying mortgage loans breach certain representations and warranties, and that the affiliate has failed to repurchase the allegedly defective loans. In addition, MBIA brought claims for fraudulent inducement, material misrepresentations, breaches of warranties, repurchase obligations, and reimbursement. MBIA submitted repurchase demands for loans with an original principal balance of approximately USD 549 million. On March 31, 2017, the SCNY granted in part and denied in part both parties’ respective summary judgment motions, which resulted, among other things, in the dismissal of MBIA’s fraudulent inducement claim with prejudice. On September 13, 2018, the First Department issued a decision that, among other things, affirmed the dismissal of MBIA’s fraudulent inducement claim with prejudice. Following its decision, the First Department remanded the action to the trial court for further proceedings. On August 2, 2019, the SCNY concluded a two-week bench trial. On November 30, 2020, the SCNY issued a post-trial order determining liability, and on January 25, 2021 entered an order setting damages in the amount of USD 604 million. On February 11, 2021, following a settlement in the amount of USD 600 million, for which Credit Suisse was fully reserved, the SCNY dismissed with prejudice all claims against CSS LLC and its affiliates. Repurchase litigations DLJ Mortgage Capital, Inc. (DLJ) is a defendant in: (i) one action brought by Asset Backed Securities Corporation Home Equity Loan Trust, Series 2006-HE7, in which plaintiff alleges damages of not less than USD 374 million, increased from not less than USD 341 million, in an amended complaint filed on August 19, 2019, which action is proceeding in the SCNY following the resolution of a previously pending appeal; on January 13, 2020, DLJ filed a motion to dismiss; (ii) one action brought by Home Equity Asset Trust, Series 2006-8, in which plaintiff alleges damages of not less than USD 436 million; (iii) one action brought by Home Equity Asset Trust 2007-1, in which plaintiff alleges damages of not less than USD 420 million; on December 27, 2018, the SCNY denied DLJ’s motion for partial summary judgment in this action, and the First Department affirmed the SCNY’s summary judgment order on October 10, 2019; on January 30, 2020, DLJ obtained leave to further appeal to the New York State Court of Appeals; subject to final resolution of DLJ’s summary judgment appeal, the SCNY has scheduled trial in this action to begin on October 11, 2021; (iv) one action brought by Home Equity Asset Trust Series 2007-3, in which plaintiff alleges damages of not less than USD 206 million; (v) one action brought by Home Equity Asset Trust 2007-2, in which plaintiff alleges damages of not less than USD 495 million; and (vi) one action brought by CSMC Asset-Backed Trust 2007-NC1, in which no damages amount is alleged. These actions are brought in the SCNY and are at various procedural stages. DLJ and its affiliate, Select Portfolio Servicing, Inc. (SPS), are defendants in two actions that have been consolidated for certain procedural purposes, including trial, in the SCNY: one action brought by Home Equity Mortgage Trust Series 2006-1, Home Equity Mortgage Trust Series 2006-3 and Home Equity Mortgage Trust Series 2006-4, in which plaintiffs allege damages of not less than USD 730 million, and allege that SPS obstructed the investigation into the full extent of the defects in the mortgage pools by refusing to afford the trustee reasonable access to certain origination files; and one action brought by Home Equity Mortgage Trust Series 2006-5, in which plaintiff alleges damages of not less than USD 500 million, and alleges that SPS likely discovered DLJ’s alleged breaches of representations and warranties but did not notify the trustee of such breaches, in alleged violation of its contractual obligations. On January 10, 2019, the SCNY denied DLJ’s motion for partial summary judgment in these actions, and the First Department affirmed the SCNY’s summary judgment order on September 17, 2019. On December 12, 2019, DLJ obtained leave to further appeal to the New York State Court of Appeals. Subject to final resolution of DLJ’s summary judgment appeal, the SCNY has scheduled trial in these actions to begin on January 10, 2022. As disclosed in Credit Suisse’s fourth quarter Financial Report of 2013, the following repurchase actions were dismissed with prejudice in 2013: the three consolidated actions brought by Home Equity Asset Trust 2006-5, Home Equity Asset Trust 2006-6 and Home Equity Asset Trust 2006-7 against DLJ. Those dismissals were upheld by the New York State Court of Appeals on February 19, 2019. On July 8, 2019, the notice of appeal plaintiffs filed before the First Department from the SCNY’s April 2017 denial of plaintiffs’ request that its 2013 dismissal decision be modified to allow plaintiffs to assert new claims not previously included in plaintiffs’ consolidated complaint was deemed dismissed when plaintiffs declined to further pursue their appeal by a court-ordered deadline. On August 15, 2019, the trustees for Home Equity Asset Trust 2006-5, Home Equity Asset Trust 2006-6 and Home Equity Asset Trust 2006-7 commenced a new repurchase action against DLJ in the SCNY, in which plaintiffs alleged damages of not less than USD 936 million, asserting substantially similar claims against DLJ as those alleged in the three consolidated repurchase actions that were dismissed with prejudice in 2013. On September 20, 2019, DLJ filed a motion to dismiss and on November 25, 2019, the SCNY entered an order dismissing this new action with prejudice. On December 20, 2019, the plaintiffs filed a notice of appeal to the First Department. Bank loan litigation CSS LLC and certain of its affiliates are the subject of certain litigation relating to certain real estate developments including Yellowstone Club and Lake Las Vegas as well as other similar real estate developments. Credit Suisse defendants in these matters arranged, and acted as the agent bank for, syndicated loans provided to borrowers affiliated with such real estate developments, and who have since gone through bankruptcy or foreclosure. Such litigation includes two cases brought in Texas and New York state courts by entities related to Highland Capital Management LP (Highland). In the case in Texas state court, a jury trial was held in December 2014 on Highland’s claim for fraudulent inducement by affirmative misrepresentation and omission. A verdict was issued for the plaintiff on its claim for fraudulent inducement by affirmative misrepresentation, but the jury rejected its claim that CSS LLC and an affiliate had committed fraudulent inducement by omission. The Texas judge held a bench trial on Highland’s remaining claims in May and June 2015, and entered judgment in the amount of USD 287 million (including prejudgment interest) for the plaintiff on September 4, 2015. Both parties appealed and on February 21, 2018 the appeals court affirmed the lower court’s decision. On March 7, 2018, the defendants filed a motion for rehearing with the appeals court. On April 2, 2018, the motion for rehearing with the appeals court was denied. On July 18, 2018, the defendants filed a request for review by the Texas Supreme Court. On December 14, 2018, the court issued an order requiring briefs on the merits in the request for review. On October 4, 2019, the Texas Supreme Court granted the request for review. On January 8, 2020, the Texas Supreme Court heard oral argument. On April 24, 2020, the Texas Supreme Court issued a ruling reversing the portion of the trial court’s judgment related to the bench trial held in May and June 2015, thereby dismissing plaintiff’s breach of contract, breach of the implied duty of good faith and fair dealing, aiding and abetting fraud, and civil conspiracy claims, including damages of approximately USD 212 million, exclusive of interest, but left standing the separate December 2014 jury verdict for plaintiff on its claim for fraudulent inducement by affirmative misrepresentation. The Texas Supreme Court has remanded the case back to the trial court for further proceedings related to the calculation of damages. On June 10, 2020, Highland filed a motion for rehearing in the Texas Supreme Court, which the court denied on October 2, 2020. In the case in New York state court, the court granted in part and denied in part CSS LLC and certain of its affiliates’ summary judgment motion. Both parties appealed that decision, but the appellate court affirmed the decision in full. The case is currently in discovery. CSS LLC and certain of its affiliates separately sued Highland-managed funds on related trades and received a favorable judgment awarding both principal owed and prejudgment interest. Highland appealed the portion of the judgment awarding prejudgment interest, however the original decision was affirmed in its entirety. The parties subsequently agreed to settle the amount owed by the Highland-managed funds under the judgment. Tax and securities law matters On May 19, 2014, Credit Suisse AG entered into settlement agreements with several US regulators regarding its US cross-border matters. As part of the agreements, Credit Suisse AG, among other things, engaged an independent corporate monitor that reports to the New York State Department of Financial Services. As of July 31, 2018, the monitor concluded both his review and his assignment. Credit Suisse AG continues to report to and cooperate with US authorities in accordance with Credit Suisse AG’s obligations under the agreements. Rates-related matters Regulatory matters Regulatory authorities in a number of jurisdictions, including the US, UK, EU and Switzerland, have for an extended period of time been conducting investigations into the setting of LIBOR and other reference rates with respect to a number of currencies, as well as the pricing of certain related derivatives. These ongoing investigations have included information requests from regulators regarding LIBOR-setting practices and reviews of the activities of various financial institutions, including Credit Suisse Group AG, which is a member of three LIBOR rate-setting panels (US Dollar LIBOR, Swiss Franc LIBOR and Euro LIBOR). Credit Suisse is cooperating fully with these investigations. In particular, it has been reported that regulators are investigating whether financial institutions engaged in an effort to manipulate LIBOR, either individually or in concert with other institutions, in order to improve market perception of these institutions’ financial health and/or to increase the value of their proprietary trading positions. In response to regulatory inquiries, Credit Suisse commissioned a review of these issues. To date, Credit Suisse has seen no evidence to suggest that it is likely to have any material exposure in connection with these issues. Regulatory authorities in a number of jurisdictions, including the Swiss Competition Commission (COMCO), the European Commission (Commission), the South African Competition Commission, and the Brazilian Competition Authority have been conducting investigations into the trading activities, information sharing and the setting of benchmark rates in the foreign exchange (including electronic trading) markets. On March 31, 2014, COMCO announced its formal investigation of numerous Swiss and international financial institutions, including Credit Suisse Group AG, in relation to the setting of exchange rates in foreign exchange trading. Credit Suisse continues to cooperate with this ongoing investigation. On July 26, 2018, Credit Suisse Group AG and certain affiliates received a Statement of Objections from the Commission, alleging that Credit Suisse entities engaged in anticompetitive practices in connection with their foreign exchange trading business. The Statement of Objections sets out the Commission’s preliminary views and does not prejudge the final outcome of its investigation. The reference rates investigations have also included information requests from regulators concerning supranational, sub-sovereign and agency (SSA) bonds and commodities (including precious metals) markets. Credit Suisse is cooperating fully with these investigations. On December 20, 2018, Credit Suisse Group AG and Credit Suisse Securities (Europe) Limited received a Statement of Objections from the Commission, alleging that Credit Suisse entities engaged in anticompetitive practices in connection with its SSA bonds trading business. The Statement of Objections sets out the Commission’s preliminary views and does not prejudge the final outcome of its investigation. The investigations are ongoing and it is too soon to predict the final outcome of the investigations. Civil litigation USD LIBOR litigation Beginning in 2011, certain Credit Suisse entities were named in various civil lawsuits filed in the US, alleging banks on the US dollar LIBOR panel manipulated US dollar LIBOR to benefit their reputation and increase profits. All remaining matters have been consolidated for pre-trial purposes into a multi-district litigation in the SDNY. The majority of the actions have been stayed since their outset, while a handful of individual actions and putative class actions have been proceeding. The Credit Suisse entities have been dismissed from all non-stayed putative class actions. In a series of rulings between 2013 and 2019 on motions to dismiss, the SDNY (i) narrowed the claims against the Credit Suisse entities and the other defendants (dismissing antitrust, Racketeer Influenced and Corrupt Organizations Act (RICO), Commodity Exchange Act, and state law claims), (ii) narrowed the set of plaintiffs who may bring claims, and (iii) narrowed the set of defendants in the LIBOR actions (including the dismissal of several Credit Suisse entities from various cases on personal jurisdiction and statute of limitation grounds). The plaintiffs have appealed several of the SDNY’s rulings to the United States Court of Appeals for the Second Circuit (Second Circuit), and two appeals remain pending. The first pending appeal was filed 2017 and is a consolidated appeal brought by a number of putative class and individual plaintiffs challenging the district courts’ dismissal of plaintiffs’ antitrust claims. The second pending appeal was filed on June 23, 2020 by the plaintiffs in one of the non-stayed putative class actions challenging the district court’s personal jurisdiction and statute of limitations rulings. Separately, on May 4, 2017, the plaintiffs in the three non-stayed putative class actions moved for class certification. On February 28, 2018, the SDNY denied certification in two of the actions and granted certification over a single antitrust claim in an action brought by over-the-counter purchasers of LIBOR-linked derivatives. In the same decision, the court dismissed Credit Suisse AG, the only remaining Credit Suisse entity in the action, from the over-the-counter action. All parties moved for immediate appellate review of the class-certification decisions, and the Second Circuit denied their petitions for review. USD ICE LIBOR litigation In January 2019, members of the US dollar Intercontinental Exchange (ICE) LIBOR panel, including Credit Suisse Group AG and certain of its affiliates, were named in three civil putative class action lawsuits alleging that panel banks suppressed US dollar ICE LIBOR to benefit defendants’ trading positions. These actions have been consolidated in the SDNY. On July 1, 2019, plaintiffs filed a consolidated complaint. On August 30, 2019, defendants filed a motion to dismiss. On March 26, 2020, the SDNY granted defendants’ motion to dismiss. On April 24, 2020, plaintiffs filed a notice of appeal. On December 28, 2020, a proposed intervener filed a motion to intervene because of the current plaintiffs’ intent to withdraw. On January 7, 2021, defendants filed a motion to dismiss the appeal based on the current plaintiffs’ intent to withdraw. On August 18, 2020, members of the ICE LIBOR panel, including Credit Suisse Group AG and certain of its affiliates, were named in a civil action in the US District Court for the Northern District of California, alleging that panel banks manipulated ICE LIBOR to profit from variable interest loans and credit cards. On November 10, 2020, plaintiffs filed a motion for preliminary and permanent injunction that seeks to enjoin the panel banks from continuing to set LIBOR or that would automatically set the benchmark to zero every day. On November 11, 2020, defendants filed a motion to transfer the case to the SDNY. CHF LIBOR litigation In February 2015, various banks that served on the Swiss franc LIBOR panel, including Credit Suisse Group AG, were named in a civil putative class action lawsuit filed in the SDNY, alleging manipulation of Swiss franc LIBOR to benefit defendants’ trading positions. On September 25, 2017, the SDNY granted defendants’ motion to dismiss all claims, but permitted the plaintiffs to file an amended complaint. Defendants filed motions to dismiss the amended complaint on February 7, 2018. On September 16, 2019, the SDNY granted defendants’ motions to dismiss, finding that the court lacked subject matter jurisdiction over the case. On October 16, 2019, plaintiffs filed a notice of appeal. SIBOR/SOR litigation In July 2016, various banks that served on the Singapore Interbank Offered Rate (SIBOR) and Singapore Swap Offer Rate (SOR) panels, including Credit Suisse Group AG and affiliates, were named in a civil putative class action lawsuit filed in the SDNY, alleging manipulation of SIBOR and SOR to benefit defendants’ trading positions. On August 18, 2017, the SDNY dismissed all claims against Credit Suisse Group AG and affiliates (and various other defendants) but granted the plaintiffs leave to amend their complaint. On October 4, 2018, the SDNY granted in part and denied in part defendants’ motion to dismiss plaintiffs’ second amended complaint, upholding antitrust claims against Credit Suisse AG and other panel bank defendants, but narrowing the claims to those related to Singapore Dollar SIBOR and dismissing all but one plaintiff from the action. The court also dismissed the RICO claims without leave to amend. On October 25, 2018, the remaining plaintiff filed a third amended complaint. The remaining defendants moved to dismiss on November 15, 2018. On July 26, 2019, the SDNY granted defendants’ motion to dismiss and denied plaintiff’s motion for leave to amend, holding that the court lacked subject matter jurisdiction over the action. On August 26, 2019, plaintiff filed a notice of appeal. Foreign exchange litigation Credit Suisse Group AG and affiliates as well as other financial institutions are named in five pending civil lawsuits in the SDNY relating to the alleged manipulation of foreign exchange rates. The first pending matter is a putative consolidated class action. On January 28, 2015, the court denied defendants’ motion to dismiss the original consolidated complaint brought by US-based investors and foreign plaintiffs who transacted in the US, but granted their motion to dismiss the claims of foreign-based investors for transactions outside of the US. In July 2015, plaintiffs filed a second consolidated amended complaint, adding additional defendants and asserting additional claims on behalf of a second putative class of exchange investors. On September 20, 2016, the SDNY granted in part and denied in part a motion to dismiss filed by the Group and affiliates, along with other financial institutions, which reduc

Significant valuation and income recognition differences between US GAAP and Swiss GAAP banking law (true and fair view)	44 Significant valuation and income recognition differences between US GAAP and Swiss GAAP banking law (true and fair view) The Group’s consolidated financial statements have been prepared in accordance with US GAAP. FINMA requires Swiss-domiciled banks which present their financial statements under either US GAAP or International Financial Reporting Standards (IFRS) to provide a narrative explanation of the major differences between Swiss GAAP banking law (true and fair view) and its primary accounting standard. The principal provisions of the Swiss Ordinance on Banks and Savings Banks (Banking Ordinance), the Swiss Financial Market Supervisory Authority’s Ordinance on Accounting (FINMA Accounting Ordinance) and the FINMA circular 2020/1, “Accounting – banks”, governing financial reporting for banks (Swiss GAAP) differ in certain aspects from US GAAP. The following are the major differences: > Refer to “Note 1 – Summary of significant accounting policies” for a detailed description of the Group’s accounting policies. Scope of consolidation Under Swiss GAAP, majority-owned subsidiaries that are not considered long-term investments or do not operate in the core business of the Group are either accounted for as financial investments or as equity method investments. US GAAP has no such exception relating to the consolidation of majority-owned subsidiaries. Foreign currency translations Under US GAAP, foreign currency translation adjustments resulting from the consolidation of branches with functional currencies other than the Swiss franc are included in AOCI in shareholders’ equity. Under Swiss GAAP, foreign currency translation adjustments from the consolidation of foreign branches are recognized in net income/(loss) from trading activities and fair value option. Under US GAAP, foreign currency measurement adjustments for available-for-sale securities are reported in AOCI, which is part of total shareholder’s equity, whereas for Swiss GAAP statutory purposes they are included in the statements of income. Investments in securities Under Swiss GAAP, classification and measurement of investments in securities depends on the nature of the investment. Non-consolidated participations Under US GAAP, investments in equity securities where a company has the ability to significantly influence the operating and financial policies of an investee are accounted for under the equity method of accounting or the fair value option. Under the equity method of accounting, a company’s share of the profit or loss as well as any impairment on the participation are reported in other revenues. Under Swiss GAAP, investments in equity securities which are held with the intention of a permanent investment or which are investments in financial industry infrastructure are included in participations irrespective of the percentage ownership of voting shares held. Other participations are initially recognized at historical cost and tested for impairment at least annually. The fair value option is not allowed for participations. Under Swiss GAAP, participations held by a company are tested for impairment on the level of each individual participation. An impairment is recorded if the carrying value of a participation exceeds its fair value. Should the fair value of an impaired participation recover in subsequent periods and such recovery is considered sustainable, the impairment from prior periods can be reversed up to the fair value but not exceeding the historical cost basis. A reversal of an impairment is recorded as extraordinary income in the statements of income. Available-for-sale debt securities Under US GAAP, available-for-sale debt securities are valued at fair value. Unrealized gains and losses due to fluctuations in fair value (including foreign exchange) are not recorded in the consolidated statements of operations but included net of tax in AOCI, which is part of total shareholders’ equity. Credit-related impairments may have to be recognized in the consolidated statements of operations if the fair value of an individual debt security decreases below its amortized cost basis due to credit-related factors. Under Swiss GAAP, available-for-sale securities are accounted for at the lower of amortized cost or market with valuation reductions and recoveries due to market fluctuations recorded in other ordinary expenses and income, respectively. Foreign exchange gains and losses are recognized in net income/(loss) from trading activities and fair value option. Non-marketable equity securities Under US GAAP, equity securities which do not have a readily determinable fair value are measured in accordance with the NAV practical expedient by using the measurement alternative or at fair value. Under Swiss GAAP, non-marketable equity securities are carried at the lower of cost or market. Allowances and provisions for credit losses Under US GAAP, allowances and provisions for credit losses on financial instruments are estimated based on a CECL model. The credit loss requirements apply to financial assets measured at amortized cost as well as off-balance sheet credit exposures, such as irrevocable loan commitments, credit guarantees and similar instruments. The credit loss requirements are based on a forward-looking, lifetime CECL model by incorporating historical experience, current conditions and reasonable and supportable forecasts of future economic conditions available as of the reporting date. Under Swiss GAAP, an incurred loss model is applied for the measurement of credit losses. Valuation allowances and provisions are recognized for credit exposures that are considered impaired. In addition, an inherent (or general) loss allowance is estimated and recognized for all loans not specifically identified as impaired which, on a portfolio basis, are considered to contain inherent losses. Fair value option Unlike US GAAP, Swiss GAAP generally does not allow the fair value option concept that creates an optional alternative measurement treatment for certain non-trading financial assets and liabilities, guarantees and commitments. The fair value option permits the use of fair value for initial and subsequent measurement with changes in fair value recorded in the consolidated statements of operations. For issued structured products that meet certain conditions, fair value measurement can be applied. The related changes in fair value of both the embedded derivative and the host contract are recorded in trading revenues, except for fair value adjustments relating to own credit that cannot be recognized in the consolidated statements of income. Impacts of changes in own credit spreads are recognized in the compensation accounts which are either recorded in other assets or other liabilities. Derivative financial instruments used for fair value hedging Under US GAAP, for fair value hedges, the carrying value of the underlying hedged items is adjusted to the change in the fair value of the hedged risk. Changes in the fair value of the related designated derivatives are recorded in the same line item of the consolidated statements of operations as the change in fair value of the hedged risk for the respective assets or liabilities. Under Swiss GAAP, the carrying value of hedged items is not adjusted. The amount representing the change in fair value of the hedged item with regard to the hedged risk is recorded in the compensation account included in other assets or other liabilities. Derivative financial instruments used for cash flow hedging Under US GAAP, the change in the fair value of a designated derivative of a cash flow hedge is reported in AOCI. Under Swiss GAAP, the change in the fair value of a designated derivative of a cash flow hedge is recorded in the compensation account included in other assets or other liabilities. Derecognition of financial instruments Under US GAAP, financial instruments are only derecognized if the transaction meets the following criteria: (i) the financial asset has been legally isolated from the transferor, (ii) the transferee has the right to repledge or resell the transferred asset, and (iii) the transferor does not maintain effective control over the transferred asset. Under Swiss GAAP, a financial instrument is derecognized when the economic control has been transferred from the seller to the buyer. A party which has the controlling ability to receive the future returns from the financial instrument and the obligation to absorb the risk of the financial instrument is deemed to have economic control over a financial instrument. Debt issuance costs Under US GAAP, debt issuance costs are presented as a direct deduction from the carrying amount of the related debt. Under Swiss GAAP, debt issuance costs are reported as a balance sheet asset in accrued income and prepaid expenses. Operating leases – lessee arrangements Under US GAAP, at commencement of an operating lease, the lessee recognizes a lease liability for future lease payments and a right-of-use asset which reflects the future benefits from the lease contract. The initial lease liability equals the present value of the future lease payments; amounts paid upfront are not included. The right-of-use asset equals the sum of the initial lease liability, initial direct costs and prepaid lease payments, with lease incentives received deducted. Operating lease costs, which include amortization and an interest component, are recognized over the remaining lease term on a straight-line basis. If the reporting entity permanently vacates premises and sub-leases a leased asset to another party at a loss, an impairment is recognized on the right-of-use asset. The impairment is determined as the difference between the carrying value of the right-of-use asset and the present value of the expected sub-lease income over the sub-lease term. Under Swiss GAAP, at commencement of an operating lease, no right-of-use assets and lease liabilities are recognized on the balance sheet of the lessee. For the calculation of the periodic lease expenses, initial direct costs, lease incentives and prepaid lease payments are considered and the total cost of a lease contract is expensed on a straight-line basis over the lease term. If the reporting entity permanently vacates premises, a provision for future payments under the lease contract is recorded, net of expected sub-lease income. Goodwill amortization Under US GAAP, goodwill is not amortized but must be tested for impairment annually or more frequently if an event or change in circumstances indicates that the goodwill may be impaired. Under Swiss GAAP, goodwill is amortized over its useful life, generally not exceeding five years, except for justified cases where a maximum useful life of up to ten years is acceptable. In addition, goodwill is tested at least annually for impairment. Amortization of intangible assets Under US GAAP, intangible assets with indefinite lives are not amortized but are tested for impairment annually or more frequently if an event or change in circumstances indicates that the asset may be impaired. Under Swiss GAAP, intangible assets are amortized over a useful life, up to a maximum of five years, in justified cases up to a maximum of ten years. In addition, these assets are tested at least annually for impairment. Guarantees US GAAP requires all guarantees to be initially recognized at fair value. Upon issuance of a guarantee, the guarantor is required to recognize a liability that reflects the initial fair value; simultaneously, a receivable is recorded to reflect the future guarantee fee income over the entire life of the guarantee. Under Swiss GAAP, only accrued or prepaid guarantee fees are recorded on the balance sheet. No guarantee liability and receivable for future guarantee fees are recorded upon issuance of a guarantee. Loan origination fees and costs US GAAP requires the deferral of fees received upfront and direct costs incurred in connection with the origination of loans not held under the fair value option. Under Swiss GAAP, only upfront payments or fees that are considered interest-related components are deferred (e.g., premiums and discounts). Fees received from the borrower which are considered service-related fees such as commitment fees, structuring fees and arrangement fees are immediately recognized in commission income. Extraordinary income and expenses Unlike US GAAP, Swiss GAAP does report certain expenses or revenues as extraordinary if the recorded income or expense is non-operating and non-recurring. Pensions and post-retirement benefits Under US GAAP, the liability and related pension expense is determined based on the projected unit credit actuarial calculation of the benefit obligation. Under Swiss GAAP, the liability and related pension expense is primarily determined based on the pension plan valuation in accordance with Swiss GAAP FER 26. A pension asset is recorded if a statutory overfunding of a pension plan leads to a future economic benefit, and a pension liability is recorded if a statutory underfunding of a pension plan leads to a future economic obligation. Employer contribution reserves must be capitalized if they represent a future economic benefit. A future economic benefit exists if the employer can reduce its future statutory annual contribution to the pension plan by releasing employer contribution reserves. Pension expenses include the required contributions defined by Swiss law, any additional contribution mandated by the pension fund trustees and any change in value of the pension asset or liability between two measurement dates as determined on the basis of the annual year-end pension plan valuation. Discontinued operations Under US GAAP, the assets and liabilities of a discontinued operation are separated from the ordinary captions of the consolidated balance sheets and are reported as discontinued operations measured at the lower of the carrying value or fair value less cost to sell. Accordingly, income and expense from discontinued operations are reported in a separate line item of the consolidated statements of operations. Under Swiss GAAP, these positions remain in their initial balance sheet captions until disposed of and continue to be valued according to the respective captions. Security collateral received in securities lending transactions Under US GAAP, security collateral received in securities lending transactions with the right to sell or repledge are recorded as assets and a corresponding liability to return the collateral is recognized. Under Swiss GAAP, security collateral received and the obligation to return collateral of securities lending transactions are not recognized on the balance sheet. Loan commitments Under US GAAP, loan commitments include all commitments to extend loans, unfunded commitments under commercial lines of credit, revolving credit lines, credit guarantees in the future and overdraft protection agreements, except for commitments that can be revoked by the Group at any time at the Group’s sole discretion without prior notice. Under Swiss GAAP, loan commitments include all commitments to extend loans, unfunded commitments under commercial lines of credit, revolving credit lines, credit guarantees in the future and overdraft protection agreements, except for commitments that can be revoked by the Group at any time at the Group’s sole discretion with a notice period not exceeding six weeks.

Summary of significant accoun_2

Summary of significant accounting policies (Policies)	12 Months Ended
	Dec. 31, 2020
Basis of presentation	The accompanying consolidated financial statements of Credit Suisse Group AG (the Group) are prepared in accordance with accounting principles generally accepted in the US (US GAAP) and are stated in Swiss francs (CHF). The financial year for the Group ends on December 31. Certain reclassifications have been made to the prior year’s consolidated financial statements to conform to the current presentation which had no impact on net income/(loss) or total shareholders’ equity. In preparing the consolidated financial statements, management is required to make estimates and assumptions including, but not limited to, the fair value measurements of certain financial assets and liabilities, the allowance for loan losses, the evaluation of variable interest entities (VIEs), the impairment of assets other than loans, recognition of deferred tax assets, tax uncertainties, pension liabilities and various contingencies. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the dates of the consolidated balance sheets and the reported amounts of revenues and expenses during the reporting period. While management evaluates its estimates and assumptions on an ongoing basis, actual results could differ materially from management’s estimates. Market conditions may increase the risk and complexity of the judgments applied in these estimates.
Principles of consolidation	Principles of consolidation The consolidated financial statements include the financial statements of the Group and its subsidiaries. The Group’s subsidiaries are entities in which it holds, directly or indirectly, more than 50% of the voting rights or where it exercises control. The Group consolidates limited partnerships in cases where it is the general partner and the limited partners do not have either substantive kick out rights and/or substantive participating rights or is a limited partner with substantive rights to kick out the general partner or dissolve the partnership and participate in significant decisions made in the ordinary course of business. The Group also consolidates VIEs if the Group is the primary beneficiary in accordance with Accounting Standards Codification (ASC) Topic 810 – Consolidation. The effects of material intercompany transactions and balances have been eliminated. Where a Group subsidiary is determined to be an investment company as defined by ASC Topic 946 – Financial Services – Investment Companies, interests in other entities held by this Group subsidiary are not consolidated and are carried at fair value. Group entities that qualify as broker-dealer entities as defined by ASC Topic 940 – Financial Services – Brokers and Dealers do not consolidate investments in voting interest entities that would otherwise qualify for consolidation when the investment is held on a temporary basis for trading purposes. In addition, subsidiaries that are strategic components of a broker-dealer’s operations are consolidated regardless of holding intent.
Foreign currency translation	Foreign currency translation Transactions denominated in currencies other than the functional currency of the related entity are recorded by remeasuring them in the functional currency of the related entity using the foreign exchange rate on the date of the transaction. As of the dates of the consolidated balance sheets, monetary assets and liabilities are reported using the year-end spot foreign exchange rates. Foreign exchange rate differences are recorded in the consolidated statements of operations. Non-monetary assets and liabilities are recorded using the historic exchange rate. For the purpose of consolidation, the assets and liabilities of Group companies with functional currencies other than the Swiss franc are translated into Swiss franc equivalents using year-end spot foreign exchange rates, whereas revenues and expenses are translated at weighted average foreign exchange rates for the period. Translation adjustments arising from consolidation are included in accumulated other comprehensive income/(loss) (AOCI) within total shareholders’ equity. Cumulative translation adjustments are released from AOCI and recorded in the consolidated statements of operations when the Group disposes and loses control of a consolidated foreign subsidiary.
Fair value measurement and option	Fair value measurement and option The fair value measurement guidance establishes a single authoritative definition of fair value and sets out a framework for measuring fair value. The fair value option creates an alternative measurement treatment for certain financial assets and financial liabilities. The fair value option can be elected at initial recognition of the eligible item or at the date when the Group enters into an agreement which gives rise to an eligible item (e.g., a firm commitment or a written loan commitment). If not elected at initial recognition, the fair value option can be applied to an item upon certain triggering events that give rise to a new basis of accounting for that item. The application of the fair value option to a financial asset or a financial liability does not change its classification on the balance sheet and the election is irrevocable. Changes in fair value resulting from the election are recorded in trading revenues. > Refer to “Fair value option” in Note 36 – Financial instruments for further information.
Cash and due from banks	Cash and due from banks Cash and due from banks consists of currency on hand, demand deposits with banks or other financial institutions and cash equivalents. Cash equivalents are defined as short-term, highly liquid instruments with original maturities of three months or less, which are held for cash management purposes. Restricted cash is any cash or cash equivalent recorded in cash and due from banks subject to restrictions imposed by a governmental or other regulatory agency that require the Group to set aside specified amounts of cash as reserves against transactions and time deposits.
Reverse repurchase and repurchase agreements	Reverse repurchase and repurchase agreements Purchases of securities under agreements to resell (reverse repurchase agreements) and securities sold under agreements to repurchase (repurchase agreements) do not constitute economic sales; therefore, they are treated as collateralized financing transactions, which are carried in the consolidated balance sheet at the amount of cash disbursed or received, respectively. Reverse repurchase agreements are recorded as collateralized assets while repurchase agreements are recorded as liabilities. The underlying securities sold continuing to be recognized in trading assets or investment securities. The fair value of securities to be repurchased and resold is monitored on a daily basis, and additional collateral is obtained as needed to protect against credit exposure. Assets and liabilities recorded under these agreements are accounted for on one of two bases, the accrual basis or the fair value basis. Under the accrual basis, interest earned on reverse repurchase agreements and interest incurred on repurchase agreements are reported in interest and dividend income and interest expense, respectively. The Group elects to apply the fair value option to selected agreements pursuant to ASC Topic 825 – Financial Instruments. Under such circumstances, the change in fair value is reported in trading revenues. Accrued interest income and expense are recorded in the same manner as under the accrual method. Reverse repurchase and repurchase agreements may be netted if they are with the same counterparty; have the same maturity date; settle through the same qualifying clearing institution and subject to a right of offset allowed by a legally enforceable master netting agreement or a central counterparty’s clearing rules.
Securities lending and borrowing transactions	Securities lending and borrowing transactions Securities borrowed and securities loaned that are cash-collateralized are included in the consolidated balance sheets at amounts equal to the cash advanced or received. If securities received as collateral in a securities lending and borrowing transaction may be sold or repledged, they are recorded as securities received as collateral in the consolidated balance sheet and a corresponding liability to return the security is recorded. Securities lending transactions against non-cash collateral in which the Group has the right to resell or repledge the collateral received are recorded at the fair value of the collateral initially received. For securities lending transactions, the Group receives cash or securities collateral in an amount generally in excess of the market value of securities lent. The Group monitors the fair value of securities borrowed and loaned on a daily basis with additional collateral obtained as necessary. Fees and interest received or paid are recorded in interest and dividend income and interest expense, respectively, on an accrual basis. If the fair value basis of accounting is elected, any resulting change in fair value is reported in trading revenues. Accrued interest income and expense are recorded in the same manner as under the accrual method.
Transfers of financial assets	Transfers of financial assets Transfers of financial assets may involve the sale of these assets to special purpose entities (SPEs), which in turn issue securities to investors. The Group values its beneficial interests in such SPEs at fair value using quoted market prices, if such positions are traded on an active exchange or financial models that incorporate observable and unobservable inputs. > Refer to “Note 35 – Transfers of financial assets and variable interest entities” for further information on the Group’s transfer activities.
Trading assets and liabilities	Trading assets and liabilities Trading assets and liabilities include debt securities, marketable equity instruments, derivative instruments, certain loans held in broker-dealer entities, commodities and precious metals. Items included in the trading portfolio are carried at fair value and classified as held for trading purposes based on management’s intent. Regular-way security transactions are recorded on a trade-date basis. Unrealized and realized gains and losses on trading positions are recorded in trading revenues.
Investment securities	Investment securities Investment securities include debt securities classified as held-to-maturity and debt securities classified as available-for-sale. Regular-way security transactions are recorded on a trade-date basis. Debt securities where the Group has the positive intent and ability to hold such securities to maturity are classified as such and are carried at amortized cost, net of any unamortized premium or discount. Debt securities classified as held-to-maturity require an assessment of the current expected credit loss (CECL) at the reporting date. Debt securities classified as available-for-sale are carried at fair value. Unrealized gains and losses, which represent the difference between fair value and amortized cost, are recorded in AOCI. Amounts reported in AOCI are net of income taxes. Debt securities classified as available-for-sale are impaired if there is a decline in fair value below amortized cost basis. If the Group intends to sell an impaired security or more likely than not will be required to sell such a security before recovering its amortized cost basis, the entire difference between the amortized cost basis and fair value is recognized as a credit loss. However, if the Group does not intend to sell and is not likely to be required to sell, an assessment is made if a decline in fair value of the security is due to credit-related factors or non-credit related factors. Credit-related impairment is recognized in earnings by recording an allowance for credit losses. Any portion of the unrealized loss that relates to non-credit related factors is recognized in AOCI, net of income taxes. Amortization of premiums or discounts for debt securities is recorded in interest and dividend income using the effective yield method through the maturity date of the security.
Other investments	Other investments Other investments include equity method investments, equity securities without a readily determinable fair value, such as hedge funds, private equity securities and certain investments in non-marketable mutual funds for which the Group has neither significant influence nor control over the investee, and real estate held-for-investment. Equity method investments are investments for which the Group has the ability to significantly influence the operating and financial policies. Significant influence is typically characterized by ownership of 20% to 50% of the voting stock or in-substance common stock of a corporation or 3% 5% Equity securities without a readily determinable fair value are carried at fair value, net asset value practical expedient to estimate fair value or at cost less impairment, adjusted for observable price changes (measurement alternative). Memberships in exchanges are reported at cost, less impairment. Equity securities without a readily determinable fair value held by the Group’s subsidiaries that are determined to be investment companies as defined by ASC Topic 946 – Financial Services – Investment Companies are carried at fair value, with changes in fair value recorded in other revenues. Equity method investments and equity securities without a readily determinable fair value held by subsidiaries that are within the scope of ASC Topic 940 – Financial Services – Brokers and Dealers are measured at fair value and reported in trading assets when the intent of the broker-dealer entity is to hold the asset temporarily for trading purposes. Changes in fair value are reported in trading revenues. Equity securities without a readily determinable fair value include investments in entities that regularly calculate net asset value per share or its equivalent, with changes in fair value recorded in other revenue. Real estate held-for-investment purposes is carried at cost less accumulated depreciation and is depreciated over its estimated useful life, generally 40 to 67 years. Land that is classified as real estate held-for-investment purposes is carried at historical cost and is not depreciated. Real estate held-for-investment purposes is tested for impairment annually, or more frequently, if events or changes in circumstances indicate that the carrying amount may not be recoverable. For real estate held-for-investment purposes, the fair values were measured based on either discounted cash flow analyses or external market appraisals. Recognition of an impairment on such assets establishes a new cost base, which is not adjusted for subsequent recoveries in value.
Loans	Loans Loans held-to-maturity Loans which the Group intends to hold until maturity are carried at outstanding principal balances plus accrued interest, net of the following items: unamortized premiums, discounts on purchased loans, deferred loan origination fees and direct loan origination costs on originated loans. Interest income is accrued on the unpaid principal balance and net deferred premiums/discounts and fees/costs are amortized as an adjustment to the loan yield over the term of the related loans. A loan is classified as non-performing and thus considered credit impaired no later than when the contractual payments of principal and/or interest are more than 90 days past due except for subprime residential loans which are classified as non-performing no later than when the contractual payments of principal and/or interest are more than 120 days past due. The additional 30 days ensure that these loans are not incorrectly assessed as non-performing during the time when servicing of them typically is being transferred. However, management may determine that a loan should be classified as non-performing notwithstanding that contractual payments of principal and/or interest are less than 90 days past due or, in the case of subprime residential loans, 120 days past due. In addition, the Group continues to add accrued interest receivable to the loan’s balance for collection purposes; however, a credit provision is recorded, resulting in no interest income recognition. A loan can be further downgraded to non-interest-earning when the collection of interest is considered so doubtful that further accrual of interest is deemed inappropriate. Generally, non-performing loans and non-interest-earning loans may be restored to performing status only when delinquent principal and interest are brought up to date in accordance with the terms of the loan agreement and when certain performance criteria are met. Interest collected on non-performing loans and non-interest-earning loans is accounted for using the cash basis or the cost recovery method or a combination of both. Amortization of deferred fees and premiums and discounts ceases while a loan is deemed to be non-performing or non-interest-earning. Loans that are modified in a troubled debt restructuring are reported as restructured loans. Generally, a restructured loan would have been considered credit-impaired prior to the restructuring. Loans modified in a troubled debt restructuring are no longer considered credit-impaired in the years following the restructuring if the restructured loan carries an interest rate that is equal to or greater than the rate the Group was willing to accept at the time of the restructuring for a loan with comparable risk and the loan is not credit-impaired based on the terms specified by the restructuring agreement. Loans that have been restructured in a troubled debt restructuring and are performing according to the new terms continue to accrue interest. Loan restructurings may include the receipt of assets in satisfaction of the loan, the modification of loan terms (e.g., reduction of interest rates, extension of maturity dates at a stated interest rate lower than the current market rate for new loans with similar risk, or reduction in principal amounts and/or accrued interest balances) or a combination of both. Potential problem loans are credit-impaired loans where contractual payments have been received according to schedule, but where doubt exists as to the collection of future contractual payments. Potential problem loans continue to accrue interest. > Refer to “Note 19 – Loans” for further information. Credit losses on financial instruments measured at amortized cost The credit loss requirements apply to financial assets measured at amortized cost including loans held-to-maturity, net investments in leases as a lessor as well as off-balance sheet credit exposures, such as irrevocable loan commitments, and credit guarantees. The credit loss requirements are based on a forward-looking, lifetime CECL model by incorporating reasonable and supportable forecasts of future economic conditions available at the reporting date. The CECL amounts are estimated over the contractual term of the financial assets taking into account the effect of prepayments. This requires considerable judgment over how changes in macroeconomic factors as well as changes in forward-looking borrower-specific characteristics will affect the CECL amounts. The Group measures expected credit losses of financial assets on a collective (pool) basis when similar risk characteristics exist. For financial assets that do not share similar risk characteristics, expected credit losses are evaluated on an individual basis. CECL amounts are probability-weighted estimates of potential credit losses based on historical frequency, current trends and conditions as well as forecasted macroeconomic factors, such as gross domestic product, unemployment rates and interest rates. For financial assets that are performing at the reporting date, the allowance for credit losses is generally measured using a probability of default/loss given default approach under which both probability of default (PD), loss given default (LGD) and exposure at default (EAD) are estimated. For financial assets that are credit-impaired at the reporting date, the Group generally applies a discounted cash flow approach to determine the difference between the gross carrying amount and the present value of estimated future cash flows. An allowance for credit losses is deducted from the amortized cost basis of the financial asset. Changes in the allowance for credit losses are recorded in the consolidated statement of operations in provision for credit losses or, if related to provisions on past due interest, in net interest income. For undrawn irrevocable loan commitments, the present value is calculated based on the difference between the contractual cash flows that are due to the Group if the commitment is drawn and the cash flows that the Group expects to receive, in order to estimate the provision for expected credit losses. For credit guarantees, expected credit losses are recognized for the contingency of the credit guarantee. Provisions for off-balance sheet credit exposures are recognized as a provision in other liabilities in the consolidated balance sheets. Write-off of a financial asset occurs when it is considered certain that there is no possibility of recovering the outstanding principal. If the amount of loss on write-off is greater than the accumulated allowance for credit losses, the difference results in an additional credit loss. The additional credit loss is first recognized as an addition to the allowance; the allowance is then applied against the gross carrying amount. Any repossessed collateral is initially measured at fair value. The subsequent measurement depends on the nature of the collateral. Any uncollectible accrued interest receivable is written off by reversing the related interest income. Expected recoveries on financial assets previously written off or assessed/planned to be written off have to be reflected in the allowance for credit losses; for this purpose, the amount of expected recoveries cannot exceed the aggregate amounts previously written off or assessed/planned to be written off. Accordingly, expected recoveries from financial assets previously written off may result in an overall negative allowance for credit loss balance. Prior to January 2020, the allowance for credit losses reflected probable incurred credit losses. > Refer to “Note 20 – Financial instruments measured at amortized cost and credit losses” for further information. Loans held-for-sale Loans, which the Group intends to sell in the foreseeable future, are considered held-for-sale and are carried at the lower of amortized cost or market value determined on either an individual method basis, or in the aggregate for pools of similar loans if sold or securitized as a pool. Loans held-for-sale are included in other assets. Adjustments to the lower of amortized cost basis or fair value are presented as a valuation allowance and recorded in other revenue. Purchased impaired loans Purchased loans for which it is probable at acquisition that all contractually required payments will not be received are recorded at their net purchase price and no allowances are carried over. The excess of the estimated cash flows to be collected over the amount paid is accreted into interest income over the estimated recovery period when reasonable estimates can be made about the timing and amount of recovery. The Group does not consider such loans to be impaired at the time of acquisition. Such loans are deemed impaired only if the Group’s estimate of cash to be received decreases below the estimate at the time of acquisition. Increases in the estimated expected recovery are recorded as a reversal of allowances, if any, and then recognized as an adjustment of the effective yield of the loan. Loans held at fair value under the fair value option Loans and loan commitments for which the fair value option is elected are reported at fair value with changes in fair value reported in trading revenues. The application of the fair value option does not change the loan’s classification. Loan commitments carried at fair value are recorded in other assets or other liabilities, respectively.
Premises and equipment	Premises and equipment Premises and equipment (including equipment under operating leases where the Group is the lessor), with the exception of land, are carried at cost less accumulated depreciation. Buildings are depreciated on a straight-line basis over their estimated useful lives, generally 40 to 67 years, and building improvements are depreciated on a straight-line basis over their estimated useful lives, generally not exceeding five to ten years. Land is carried at historical cost and is not depreciated. Leasehold improvements, such as alterations and improvements to rented premises, are depreciated on a straight-line basis over the shorter of the lease term or estimated useful life, which generally does not exceed ten years. Equipment, such as computers, machinery, furnishings, vehicles and other tangible non-financial assets, is depreciated using the straight-line method over its estimated useful lives, generally three to ten years. Certain leasehold improvements and equipment, such as data center power generators, may have estimated useful lives greater than ten years. The Group capitalizes costs relating to the acquisition, installation and development of software with a measurable economic benefit, but only if such costs are identifiable and can be reliably measured. The Group depreciates capitalized software costs on a straight-line basis over the estimated useful life of the software, generally not exceeding seven years, taking into consideration the effects of obsolescence, technology, competition and other economic factors.
Lessor, Leases	For sales-type and direct financing leases under lessor arrangements, which are classified as loans, the Group de-recognizes the underlying assets and recognizes a net investment in the lease. The net investment in the lease is calculated as the lease receivable plus the unguaranteed portion of the estimated residual value. The lease receivable is initially measured at the present value of the sum of the future lease payments receivable over the lease term and any portion of the estimated residual value at the end of the lease term that is guaranteed by either the lessee or an unrelated third party. Lease terms may include options that permit the lessee to extend or renew these leases. Such options are only included in the measurement of lease receivables for sales-type and direct financing leases when it is reasonably certain that the lessee would exercise these options. Subsequently, unearned income is amortized to interest income over the lease term using the effective interest method. > Refer to “Note 19 – Loans”, “Note 20 – Financial instruments measured at amortized cost and credit losses” and “Note 24 – Leases” for further information. For operating leases under lessor arrangements, the Group continues to recognize the underlying asset and depreciates the asset over its estimated useful life. Lease income is recognized in other income on a straight-line basis over the lease term.
Lessee, Leases	Leases For lessee arrangements, the Group recognizes lease liabilities, which are reported as other liabilities or long-term debt, and right-of-use assets, which are reported as other assets. Lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Right-of-use assets are initially measured based on the lease liability, adjusted for any initial direct costs, any lease payments made prior to lease commencement and for any lease incentives. > Refer to “Note 23 – Other assets and other liabilities”, “Note 24 – Leases” and “Note 26 – Long-term debt” for further information. Options that permit the Group to extend or terminate a lease are only included in the measurement of right-of-use assets and lease liabilities when it is reasonably certain that the Group would exercise the extension option or would not exercise the termination option. Lease payments, which depend on an index or a referenced rate, are considered unavoidable and are included in the lease liabilities using the index or rate as of the lease commencement date. Other variable lease payments, as well as subsequent changes in an index or referenced rate, are excluded from the lease liabilities. The Group’s incremental borrowing rate, which is used in determining the present value of lease payments, is derived from information available at the lease commencement date. Operating lease costs, which include amortization and an interest component, are recognized over the remaining lease term on a straight-line basis. Operating and variable lease costs are recognized in general and administrative expenses.
Goodwill and other intangible assets	Goodwill and other intangible assets Goodwill arises on the acquisition of subsidiaries and equity method investments. It is measured as the excess of the fair value of the consideration transferred, the fair value of any noncontrolling interest in the acquiree and the fair value of any previously held equity interest in the acquired subsidiary, over the net of the acquisition-date fair values of the identifiable assets acquired and the liabilities assumed. Goodwill is not amortized; instead it is tested for impairment annually, or more frequently if events or changes in circumstances indicate that goodwill may be impaired. Goodwill is allocated to the Group’s reporting units for the purposes of the impairment test. Other intangible assets may be acquired individually or as part of a group of assets assumed in a business combination. Other intangible assets include but are not limited to: patents, licenses, copyrights, trademarks, branch networks, mortgage servicing rights, customer base and deposit relationships. Acquired intangible assets are initially measured at the amount of cash disbursed or the fair value of other assets distributed. Other intangible assets that have a finite useful life are amortized over that period. Other intangible assets acquired after January 1, 2002 that are determined to have an indefinite useful life are not amortized; instead they are tested for impairment annually, or more frequently if events or changes in circumstances indicate that the indefinite intangible asset may be impaired. Mortgage servicing rights are included in non-amortizing other intangible assets and are carried at fair value, with changes in fair value recognized through earnings in the period in which they occur. Mortgage servicing rights represent the right to perform specified mortgage servicing activities on behalf of third parties. Mortgage servicing rights are either purchased from third parties or retained upon sale of acquired or originated loans.
Recognition of an impairment on tangible fixed assets and other intangible assets	Recognition of an impairment on non-financial assets The Group evaluates premises, equipment, right-of-use assets and finite intangible assets for impairment at least annually and whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. The impairment assessment is performed for a group of assets for which largely separate cash flows can be identified. Where the carrying amount for the group of assets exceeds the recoverable amount, the group of assets is considered impaired and an impairment is recorded in general and administrative expenses. Recognition of an impairment on such assets establishes a new cost base, which is not adjusted for subsequent recoveries in value.
Income taxes	Income taxes Deferred tax assets and liabilities are recorded for the expected future tax consequences of temporary differences between the carrying amounts of assets and liabilities at the dates of the consolidated balance sheets and their respective tax bases. Deferred tax assets and liabilities are computed using currently enacted tax rates and are recorded in other assets and other liabilities, respectively. Income tax expense or benefit is recorded in income tax expense/(benefit), except to the extent the tax effect relates to transactions recorded directly in total shareholders’ equity. Deferred tax assets are reduced by a valuation allowance, if necessary, to the amount that management believes will more likely than not be realized. Deferred tax assets and liabilities are adjusted for the effect of changes in tax laws and rates in the period in which changes are approved by the relevant authority. Deferred tax assets and liabilities are presented on a net basis for the same tax-paying component within the same tax jurisdiction. The Group follows the guidance in ASC Topic 740 – Income Taxes, which sets out a consistent framework to determine the appropriate level of tax reserves to maintain for uncertain tax positions. The Group determines whether it is more likely than not that an income tax position will be sustained upon examination based on the technical merits of the position. Sustainable income tax positions are then measured to determine the amount of benefit eligible for recognition in the consolidated financial statements. Each such sustainable income tax position is measured at the largest amount of benefit that is more likely than not to be realized upon ultimate settlement.
Brokerage receivables and brokerage payables	Brokerage receivables and brokerage payables The Group recognizes receivables and payables from transactions in financial instruments purchased from and sold to customers, banks and broker-dealers. The Group is exposed to risk of loss resulting from the inability of counterparties to pay for or deliver financial instruments purchased or sold, in which case the Group would have to sell or purchase, respectively, these financial instruments at prevailing market prices. To the extent an exchange or clearing organization acts as counterparty to a transaction, credit risk is generally considered to be limited. The Group establishes credit limits for each customer and requires them to maintain margin collateral in compliance with applicable regulatory and internal guidelines. In order to conduct trades with an exchange or a third-party bank, the Group is required to maintain a margin. This is usually in the form of cash and deposited in a separate margin account with the exchange or broker. If available information indicates that it is probable that a brokerage receivable is impaired, an allowance is established. Write-offs of brokerage receivables occur if the outstanding amounts are considered uncollectible.
Other assets - Derivatives used for hedging	Derivatives Freestanding derivative contracts are carried at fair value in the consolidated balance sheets regardless of whether these instruments are held for trading or risk management purposes. Commitments to originate mortgage loans that will be held for sale are considered derivatives for accounting purposes. When derivative features embedded in certain contracts that meet the definition of a derivative are not considered clearly and closely related to the host contract, either the embedded feature is accounted for separately at fair value or the entire contract, including the embedded feature, is accounted for at fair value. In both cases, changes in fair value are recorded in the consolidated statements of operations. If separated for measurement purposes, the derivative is recorded in the same line item in the consolidated balance sheets as the host contract. Derivatives classified as trading assets and liabilities include those held for trading purposes and those used for risk management purposes that do not qualify for hedge accounting. Derivatives held for trading purposes arise from proprietary trading activity and from customer-based activity. Realized gains and losses, changes in unrealized gains and losses and interest flows are included in trading revenues. Derivative contracts designated and qualifying as fair value hedges, cash flow hedges or net investment hedges are reported as other assets or other liabilities. The fair value of exchange-traded derivatives is typically derived from observable market prices and/or observable market parameters. Fair values for over-the-counter (OTC) derivatives are determined on the basis of proprietary models using various input parameters. Derivative contracts are recorded on a net basis per counterparty where a right to offset exists under an enforceable master netting agreement or a central counterparty’s clearing rules. Where no such rights exist, fair values are recorded on a gross basis. Where hedge accounting is applied, the Group formally documents all relationships between hedging instruments and hedged items, including the risk management objectives and strategy for undertaking hedge transactions. At inception of a hedge and on an ongoing basis, the hedge relationship is formally assessed to determine whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flows of hedged items attributable to the hedged risk. The Group discontinues hedge accounting prospectively in the following circumstances: (i) the derivative is no longer effective in offsetting changes in the fair value or cash flows of a hedged item (including forecasted transactions); (ii) the derivative expires or is sold, terminated or exercised; (iii) the derivative is no longer designated as a hedging instrument because it is unlikely that the forecasted transaction will occur; or (iv) the designation of the derivative as a hedging instrument is otherwise no longer appropriate. For derivatives that are designated and qualify as fair value hedges, the carrying values of the underlying hedged items are adjusted to fair value for the risk being hedged. Changes in the fair value of these derivatives are recorded in the same line item of the consolidated statements of operations used to present the changes in the fair value of the hedged item. When the Group discontinues fair value hedge accounting because it determines that the derivative no longer qualifies as an effective hedge, the derivative will continue to be carried in the consolidated balance sheets at its fair value, and the hedged asset or liability will no longer be adjusted for changes in fair value attributable to the hedged risk. Interest-related fair value adjustments made to the underlying hedged items will be amortized to the consolidated statements of operations over the remaining life of the hedged item. Any unamortized interest-related fair value adjustment is recorded in the consolidated statements of operations upon sale or extinguishment of the hedged asset or liability, respectively. Any other fair value hedge adjustments remain part of the carrying amount of the hedged asset or liability and are recognized in the consolidated statements of operations upon disposition of the hedged item as part of the gain or loss on disposition. For hedges of the variability of cash flows from forecasted transactions and floating rate assets or liabilities, the change in the fair value of a designated derivative is recorded in AOCI. These amounts are reclassified into the line item in the consolidated statements of operations in which the hedged item is recorded when the variable cash flow from the hedged item impacts earnings (for example, when periodic settlements on a variable rate asset or liability are recorded in the consolidated statements of operations or when the hedged item is disposed of). When hedge accounting is discontinued on a cash flow hedge, the net gain or loss will remain in AOCI and be reclassified into the consolidated statements of operations in the same period or periods during which the formerly hedged transaction is reported in the consolidated statements of operations. When the Group discontinues hedge accounting because it is probable that a forecasted transaction will not occur within the specified date or period plus two months, the derivative will continue to be carried in the consolidated balance sheets at its fair value, and gains and losses that were previously recorded in AOCI will be recognized immediately in the consolidated statements of operations. For hedges of a net investment in a foreign operation, the change in the fair value of the hedging derivative is recorded in AOCI. The Group uses the forward method of determining effectiveness for net investment hedges, which results in the time value portion of a foreign currency forward being reported in AOCI.
Customer deposits	Customer deposits Customer deposits represent funds held from customers (both retail and commercial) and banks and consist of interest-bearing demand deposits, savings deposits and time deposits. Interest is accrued based on the contractual provisions of the deposit contract.
Long-term debt	Long-term debt Total long-term debt is composed of debt issuances that do not contain derivative features as well as hybrid debt. Hybrid debt includes capital instruments as well as those issued as part of the Group’s structured product activities. Long-term debt includes both Swiss franc and foreign currency denominated fixed and variable rate bonds. The Group actively manages interest rate risk and foreign currency risk on vanilla debt through the use of derivative contracts, primarily interest rate and currency swaps. In particular, fixed rate debt is hedged with receive-fixed, pay-floating interest rate swaps, and the Group applies hedge accounting per the guidance of ASC Topic 815 – Derivatives and Hedging. For capital management purposes, the Group has outstanding hybrid capital instruments in the form of low- and high-trigger tier 1 and tier 2 capital notes, with a write-off or contingent share conversion feature. Typically, these instruments have an embedded derivative that is bifurcated for accounting purposes. The embedded derivative is measured separately and changes in fair value are recorded in trading revenue. The host contract is generally accounted for under the amortized cost method unless the fair value option has been elected and the entire instrument is carried at fair value. The Group’s long-term debt also includes various equity-linked and other indexed instruments with embedded derivative features, for which payments and redemption values are linked to commodities, stocks, indices, currencies or other assets. The Group elected to account for substantially all of these instruments at fair value. Changes in the fair value of fair-value option elected instruments are recognized as a component of trading revenues, except for changes in fair value attributed to own credit risk, which is recorded in other comprehensive income (OCI), net of tax, and recycled to trading revenue when the debt is de-recognized.
Other liabilities	Guarantees In cases where the Group acts as a guarantor, the Group recognizes in other liabilities, at the inception of a guarantee, a liability for the fair value of the obligations undertaken in issuing such a guarantee, including its ongoing obligation to perform over the term of the guarantee in the event that certain events or conditions occur. Contingent obligations under issued guarantees not related to a financial obligation such as performance guarantees and non-financial standby letters of credit are assessed for the probability of loss on an ongoing basis. Contingent obligations under issued guarantees related to a financial obligation such as credit guarantees and financial standby letters of credit are assessed for CECL at reporting date.
Share-based compensation	Share-based compensation For all share-based awards granted to employees, compensation expense is measured at grant date or modification date based on the fair value of the number of awards for which the requisite service is expected to be rendered and is recognized in the consolidated statements of operations over the required service period. The incremental tax effects of the difference between the compensation expense recorded in the US GAAP accounts and the tax deduction received, are recorded in the income statement at the point in time the deduction for tax purposes is recorded. Compensation expense for share-based awards that vest in their entirety at the end of the vesting period (cliff vesting) and awards that vest in annual installments (graded vesting), which only contain a service condition that affects vesting, is recognized on a straight-line basis over the service period for the entire award. However, if awards with graded vesting contain a performance condition, then each installment is expensed as if it were a separate award (“front-loaded” expense recognition). Furthermore, recognition of compensation expense is accelerated to the date an employee becomes eligible for retirement. Performance share awards contain a performance condition. In the event of either a negative return on equity (ROE) of the Group or a divisional loss, any outstanding performance share awards will be subject to a reduction. The amount of compensation expense recorded includes an estimate of any expected reductions. For each reporting period after the grant date, the expected number of shares to be ultimately delivered upon vesting is reassessed and reflected as an adjustment to the cumulative compensation expense recorded in the income statement. The basis for the ROE calculation may vary from year to year, depending on the Compensation Committee’s determination for the year in which the performance shares are granted. Certain employees own equity interests in the form of carried interests in certain funds managed by the Group. Expenses recognized under these ownership interests are reflected in the consolidated statements of operations in compensation and benefits.
Pensions and other post-retirement benefits	Pension and other post-retirement benefits Credit Suisse sponsors a number of post-employment benefit plans for its employees worldwide, which include defined benefit pension plans and other post-employment benefits. The major plans are located in Switzerland, the UK and the US. The Group uses the projected unit credit actuarial method to determine the present value of its projected benefit obligations (PBO) and the current and past service costs or credits related to its defined benefit and other post-retirement benefit plans. The measurement date used to perform the actuarial valuation is December 31 and is performed by independent qualified actuaries. Certain key assumptions are used in performing the actuarial valuations. These assumptions must be made concerning the future events that will determine the amount and timing of the benefit payments and thus require significant judgment and estimates by Group management. This includes making assumptions with regard to discount rates, salary increases, interest rate on savings balances, expected long-term rate of return on plan assets and mortality (future life expectancy). The assumed discount rates reflect the rates at which the pension benefits could be effectively settled. These rates are determined based on yield curves, constructed from high-quality corporate bonds currently available and observable in the market and are expected to be available during the period to maturity of the pension benefits. In countries where there is no deep market in high-quality corporate bonds with longer durations, the best available market information, including governmental bond yields and risk premiums, is used to construct the yield curve. Salary increases are determined by reviewing historical practice and external market data as well as considering internal projections. The interest rate on savings balances is applicable only to the Credit Suisse Swiss pension plan (Swiss pension plan). The Board of Trustees of the Swiss pension plan sets the interest rate to be applied on the accumulated savings balance on an annual basis. Credit Suisse estimates the future interest rate on savings balances, taking into consideration actions and rates approved by the Board of Trustees of the Swiss pension plan and expected future changes in the interest rate environment based on the yield curve used for the discount rate. The expected long-term rate of return on plan assets is determined on a plan-by-plan basis, taking into account asset allocation, historical rate of return, benchmark indices for similar-type pension plan assets, long-term expectations of future returns and investment strategy. Mortality assumptions are based on standard mortality tables and standard models and methodologies for projecting future improvements to mortality as developed and published by external independent actuarial societies and actuarial organizations. Health care cost trend rates are determined by reviewing external data and the Group’s own historical trends for health care costs. The funded status of the Group’s defined benefit post-retirement and pension plans is recognized in the consolidated balance sheets. Actuarial gains and losses in excess of 10% of the greater of the PBO or the market value of plan assets are amortized to net periodic pension and other post-retirement benefit costs on a straight-line basis over the average remaining service life of active employees expected to receive benefits. If all or almost all of the participants are inactive, the amortization period is based on the average remaining life expectancy of the inactive participants. Unrecognized prior service costs or credits are amortized over the remaining service period of employees affected by a plan amendment. The Group records pension expense for defined contribution plans when the employee renders service to the company, essentially coinciding with the cash contributions to the plans.
Own shares, own bonds and financial instruments on own shares	Own shares, own bonds and financial instruments on own shares The Group may buy and sell own shares, own bonds and financial instruments on own shares within its normal trading and market-making activities. In addition, the Group may hold its own shares to satisfy commitments arising from employee share-based compensation awards. Own shares are recorded at cost and reported as treasury shares, resulting in a reduction to total shareholders’ equity. Financial instruments on own shares are recorded as assets or liabilities or as equity when the criteria for equity classification are met. Dividends received by subsidiaries on own shares and unrealized and realized gains and losses on own shares classified in total shareholders’ equity are excluded from the consolidated statements of operations. Any holdings of bonds issued by any Group entity are eliminated in the consolidated financial statements.
Net interest income	Net interest income Interest income and interest expense arising from interest-bearing assets and liabilities other than those carried at fair value or the lower of cost or market are accrued, and any related net deferred premiums, discounts, origination fees or costs are amortized as an adjustment to the yield over the life of the related asset and liability. Interest from debt securities and dividends on equity securities carried as trading assets and trading liabilities are recorded in interest and dividend income. > Refer to “Loans” for further information on interest on loans.
Commissions and fees	Commissions and fees Commissions and fees include revenue from contracts with customers. The Group recognizes revenue when it satisfies a contractual performance obligation. The Group satisfies a performance obligation when control of the underlying good or services related to the performance obligation is transferred to the customer. Control is the ability to direct the use of, and obtain substantially all of the remaining benefits from, the good or service. The Group must determine whether control of a good or service is transferred over time. If so, the related revenue is recognized over time as the good or service is transferred to the customer. If not, control of the good or service is transferred at a point in time. The performance obligations are typically satisfied as the services in the contract are rendered. Revenue is measured based on the consideration specified in a contract with a customer, and excludes any amounts collected on behalf of third parties. The transaction price can be a fixed amount or can vary because of performance bonuses or other similar items. Variable consideration is only included in the transaction price once it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the amount of variable consideration is subsequently resolved. Generally, no significant judgement is required with respect to recording variable consideration. When another party is involved in providing goods or services to a customer, the Group must determine whether the nature of its promise is a performance obligation to provide the specified goods or services itself (that is, the Group is a principal) or to arrange for those goods or services to be provided by the other party (that is, the Group is an agent). The Group determines whether it is a principal or an agent for each specified good or service promised to the customer. Gross presentation (revenue on the revenue line and expense on the expense line) is appropriate when the Group acts as principal in a transaction. Conversely, net presentation (revenue and expenses reported net) is appropriate when the Group acts as an agent in the transaction. Transaction-related expenses are expensed as incurred. Underwriting expenses are deferred and recognized along with the underwriting revenue. > Refer to “Note 14 – Revenue from contracts with customers” for further information.
Bank
Basis of presentation	The accompanying consolidated financial statements of Credit Suisse AG (the Bank), the direct bank subsidiary of Credit Suisse Group AG (the Group), are prepared in accordance with accounting principles generally accepted in the US (US GAAP) and are stated in Swiss francs (CHF). The financial year for the Bank ends on December 31. Certain reclassifications have been made to the prior year’s consolidated financial statements to conform to the current presentation which had no impact on net income/(loss) or total shareholders’ equity. In preparing the consolidated financial statements, management is required to make estimates and assumptions including, but not limited to, the fair value measurements of certain financial assets and liabilities, the allowance for loan losses, the evaluation of variable interest entities (VIEs), the impairment of assets other than loans, recognition of deferred tax assets, tax uncertainties, pension liabilities and various contingencies. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the dates of the consolidated balance sheets and the reported amounts of revenues and expenses during the reporting period. While management evaluates its estimates and assumptions on an ongoing basis, actual results could differ materially from management’s estimates. Market conditions may increase the risk and complexity of the judgments applied in these estimates. > Refer to “Note 1 – Summary of significant accounting policies” in VI – Consolidated financial statements – Credit Suisse Group for a summary of significant accounting policies, with the exception of the following accounting policies.
Pensions and other post-retirement benefits	Pension and other post-retirement benefits Credit Suisse sponsors a Group defined benefit pension plan in Switzerland that covers eligible employees of the Bank domiciled in Switzerland. The Bank also has single-employer defined benefit pension plans and defined contribution pension plans in Switzerland and other countries around the world. For the Bank’s participation in the Group defined benefit pension plan, no retirement benefit obligation is recognized in the consolidated balance sheets of the Bank and defined contribution accounting is applied, as the Bank is not the sponsoring entity of the Group plan. For single-employer defined benefit plans, the Bank uses the projected unit credit actuarial method to determine the present value of its projected benefit obligations (PBO) and the current and past service costs or credits related to its defined benefit and other post-retirement benefit plans. The measurement date used to perform the actuarial valuation is December 31 and is performed by independent qualified actuaries. > Refer to “Pension and other post-retirement benefits” in VI – Consolidated financial statements – Credit Suisse Group – Note 1 – Summary of significant accounting policies for further information.
Own shares, own bonds and financial instruments on own shares	Own shares, own bonds and financial instruments on Group shares The Bank’s shares are wholly owned by Credit Suisse Group AG and are not subject to trading. The Bank may buy and sell Credit Suisse Group AG shares (Group shares) and Group bonds, own bonds and financial instruments on Group shares within its normal trading and market-making activities. In addition, the Bank may hold Group shares to economically hedge commitments arising from employee share-based compensation awards. Group shares are reported as trading assets, unless those shares are held to economically hedge share award obligations. Hedging shares are reported as treasury shares, resulting in a reduction to total shareholder’s equity. Financial instruments on Group shares are recorded as assets or liabilities and carried at fair value. Dividends received on Group shares and unrealized and realized gains and losses on Group shares are recorded according to the classification of the shares as trading assets or treasury shares. Purchases of bonds originally issued by the Bank are recorded as an extinguishment of debt.

PSA utilizes the constant prepayment rate (CPR) assumptions. A 100% prepayment assumption assumes a prepayment rate of 0.2% per annum of the outstanding principal balance of mortgage loans in the first month. This increases by 0.2 percentage points thereafter during the term of the mortgage loan, leveling off to a CPR of 6% per annum beginning in the 30th month and each month thereafter during the term of the mortgage loan. 100 PSA equals 6 CPR. 2 To deter prepayment, commercial mortgage loans typically have prepayment protection in the form of prepayment lockouts and yield maintenances. 3 The rate is based on the weighted-average yield on the beneficial interests. 4 The range of expected credit losses only reflects instruments with an expected credit loss greater than zero unless all of the instruments have an expected credit loss of zero.

This increases by 0.2 percentage points thereafter during the term of the mortgage loan, leveling off to a CPR of 6% per annum beginning in the 30th month and each month thereafter during the term of the mortgage loan. 100 PSA equals 6 CPR. 4 The rate is based on the weighted-average yield on the beneficial interests. 5 The range of expected credit losses only reflects instruments with an expected credit loss greater than zero unless all of the instruments have an expected credit loss of zero.

Subsequent Event [Line Items]
Subsequent Event, Date	Mar. 1, 2021
Subsequent Event, Description	On March 1, 2021, the boards of the supply chain finance funds managed by certain Group subsidiaries decided to suspend redemptions and subscriptions of those funds to protect the interests of the funds’ investors. On March 4, 2021, the boards decided to terminate those funds and proceed to their liquidation. Those decisions were based on concerns that a substantial part of the funds’ assets was subject to considerable valuation uncertainty. Credit Suisse Asset Management (Schweiz) AG (CSAM) acts as the portfolio manager of these supply chain finance funds. Redemptions and subscriptions of certain other funds managed by CSAM or CSAM subsidiaries that invest in part in these supply chain finance funds have also been suspended. The assets held by the supply chain finance funds, largely consisting of notes backed by existing and future receivables, were originated and structured by Greensill Capital (UK) Limited or one of its affiliates (Greensill Capital). The last published net asset value of the supply chain finance funds in late February was approximately USD 10 billion in the aggregate. Initial redemption payments totaling USD 3.1 billion across the supply chain finance funds were made to their investors beginning on March 8, 2021. The portfolio manager continues to work to liquidate the remaining assets in the four funds as the receivables comprising the funds’ assets mature. Greensill Capital filed for insolvency in the UK on March 8, 2021, and the portfolio manager is working closely with the administrators of Greensill Capital, Grant Thornton, and with other parties to facilitate this process. However, there remains considerable uncertainty regarding the valuation of a significant part of the remaining assets, including the fact that the portfolio manager has been informed that certain of the notes underlying the funds will not be repaid when they fall due, and the amounts that ultimately will be distributed to investors in respect of the funds. Group subsidiaries also have collateralized bridge lending and other direct and indirect exposures to Greensill Capital, including exposures relating to certain fund-linked products. With regard to the outstanding collateralized bridge loan of USD 140 million, USD 50 million was recently repaid by the administrators of Greensill Capital, reducing the outstanding amount of the loan to USD 90 million. The Group continues to analyze these matters, including with the assistance of external counsel and other experts. The Board of Directors has also initiated an investigation of these matters. It has been decided that as of March 10, 2021, three senior CSAM employees will not be performing their roles for the time being. The payout and vesting of variable compensation of a number of senior employees involved in these matters, up to and including Executive Board members, has been suspended as a measure to ensure that the Group can reconsider the variable compensation for 2020 and are able to apply malus or clawback, if appropriate. A number of regulatory investigations and actions have been initiated or are being considered in respect of these matters, including by FINMA, one of which is the agreement to a Pillar 2 buffer with Credit Suisse. Furthermore, certain investors have already threatened litigation and, as this matter develops, Credit Suisse may become subject to litigation, disputes or other actions. The priority for Credit Suisse remains the recovery of funds for CSAM’s investors, and the portfolio manager is working closely with the administrators to facilitate this process.
Subsequent Event, Amount Inestimable	Credit Suisse notes that it is reasonably possible that Credit Suisse will incur a loss in respect of these matters, albeit that given the early stage of this process, it is not yet possible to estimate the size of such a reasonably possible loss. However, the ultimate cost to the Group of resolving these matters may be material to its operating results. Credit Suisse might also suffer reputational harm associated with these matters that might cause client departures or loss of assets under management.

Income Statement, Balance Sheet and Additional Disclosures by Disposal Groups, Including Discontinued Operations [Line Items]
Disposal Group, Including Discontinued Operation, Description and Timing of Disposal	In the fourth quarter of 2020, York Capital Management (York) informed its investors of a significant change in strategy. As a result, York will focus on longer duration assets such as private equity, private debt and collateralized loan obligations, while winding down its European hedge funds business and primarily managing internal capital in its multi-strategy fund. York’s Asia Pacific business is expected to be spun off as a new and separate hedge fund in 2021, in which the Group intends to have a continuing interest. As a result of this announcement, the Group recorded an impairment of CHF 414 million to the valuation of its noncontrolling interest that it has owned since 2010, recognized in other revenues.

Share-based Compensation Arrangement by Share-based Payment Award [Line Items]
Share-based Compensation Arrangement by Share-based Payment Award, Terms of Award		Managing directors and all material risk takers and controllers (employees whose activities are considered to have a potentially material impact on the Group's risk profile) received a portion of their deferred variable compensation in the form of performance share awards. Performance share awards are similar to share awards, except that the full balance of outstanding performance share awards, including those awarded in prior years, are subject to performance-based malus provisions. Performance share awards are subject to a negative adjustment in the event of a divisional loss by the division in which the employees worked as of December 31, 2020, or a negative ROE of the Group, whichever results in a larger adjustment. For employees in corporate functions and the Asset Resolution Unit, the negative adjustment only applies in the event of a negative ROE of the Group and is not linked to the performance of the divisions. The basis for the ROE calculation may vary from year to year, depending on the Compensation Committee’s determination for the year in which the performance shares are granted.

Method of Measuring Cost of Award		The number of performance share awards granted to employees was generally determined by dividing the deferred component of variable compensation being granted as performance share awards by the average price of a Group share over the ten consecutive trading days which ended on March 4, 2021. The fair value of each performance share award was CHF 12.59, the Group share price on the grant date. The majority of performance share awards granted include the right to receive dividend equivalents on vested shares.

Deferred Compensation Arrangement with Individual, Excluding Share-based Payments and Postretirement Benefits [Line Items]
Deferred Compensation Arrangement with Individual, Description	CCA were granted in February 2021, 2020 and 2019 to managing directors and directors as part of the 2020, 2019 and 2018 deferred variable compensation and have rights and risks similar to those of certain contingent capital instruments issued by the Group in the market. CCA are scheduled to vest on the third anniversary of the grant date, other than those granted to individuals classified as risk managers or senior managers under the UK PRA Remuneration Code or similar regulations in other jurisdictions, where CCA vest on the fifth and seventh anniversaries of the grant date, respectively, and will be expensed over the vesting period. CCA generally provide a conditional right to receive semi-annual cash payments of interest equivalents until settled, with rates being dependent upon the vesting period and currency of denomination. CCA granted in 2021, 2020 and 2019 that vest five or seven years from the date of grant are not eligible for semi-annual cash payments of interest equivalents. CCA granted to certain regulated employees that vest over three years are not eligible for semi-annual cash payments of interest equivalents. p CCA granted in 2021 that are denominated in US dollars and vest three years from the date of grant receive interest equivalents at a rate of 3.60%, per annum plus the daily compounded (spread exclusive) US dollar Secured Overnight Financing Rate (SOFR); p CCA granted in 2020 and 2019 that are denominated in US dollars and vest three years from the date of grant receive interest equivalents at a rate of 3.77% and 4.46% respectively, per annum over the six-month US dollar LIBOR; p CCA granted in 2021 that are denominated in Swiss francs and vest three years from the date of grant receive interest equivalents at a rate of 3.06%, per annum plus the daily compounded (spread exclusive) Swiss franc Swiss Average Rate Overnight (SARON); p CCA granted in 2020 and 2019 that are denominated in Swiss francs and vest three years from the date of grant receive interest equivalents at a rate of 3.29% and 3.73%, respectively, per annum over the six-month Swiss franc LIBOR; and p The semi-annual interest equivalent cash payments calculation cycle with effect from February 2021 will be based on the SOFR for CCA denominated in US dollars and the SARON for CCA denominated in Swiss francs. The rates were set in line with market conditions at the time of grant and existing high-trigger and low-trigger contingent capital instruments that the Group has issued. For CCA granted in February 2021, employees who received compensation in Swiss francs received CCA denominated in Swiss francs and all other employees received CCA denominated in US dollars. As CCA qualify as going concern loss-absorbing capital of the Group, the timing and form of distribution upon settlement is subject to approval by FINMA. At settlement, employees will receive either a contingent capital instrument or a cash payment based on the fair value of the CCA. The fair value will be determined by the Group. In the case of a cash settlement, the CCA award will be converted into the local currency of each respective employee. CCA have loss-absorbing features such that prior to settlement, the principal amount of the CCA would be written down to zero and forfeited if any of the following trigger events were to occur: p the Group's reported common equity tier 1 (CET1) ratio falls below 7%; or p FINMA determines that cancellation of the CCA and other similar contingent capital instruments is necessary, or that the Group requires public sector capital support, in either case to prevent it from becoming insolvent or otherwise failing.

Description of Other Regulatory Limitations	Certain of the Group’s subsidiaries are subject to legal restrictions governing the amount of dividends they can pay (for example, pursuant to corporate law as defined by the Swiss Code of Obligations). Under the Swiss Code of Obligations, dividends may be paid out only if and to the extent the corporation has distributable profits from previous business years, or if the free reserves of the corporation are sufficient to allow distribution of a dividend. In addition, at least 5% of the annual net profits must be retained and booked as general legal reserves for so long as these reserves amount to less than 20% of the paid-in share capital. The reserves currently exceed this 20% threshold. Furthermore, dividends may be paid out only after shareholder approval at the Annual General Meeting.
