Summary of significant accounti

Summary of significant accounting policies	1 Summary of significant accounting policies Overview 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. Certain accounting changes As noted in our 2021 Annual Report, the Group identified an accounting issue that was not material to the prior period financial statements. The Group identified this accounting issue with respect to the net balance sheet treatment relating to the presentation of a limited population of certain securities lending and borrowing activities. As a result, balance sheet and cash flow positions for both assets and liabilities relating to these activities were presented on a gross basis and prior periods were revised in the consolidated financial statements and the related notes. Beginning with the quarter ended June 30, 2022, the Group has presented these securities lending and borrowing transactions as a single unit of account and as a result these transactions will no longer be presented on a gross basis. The Group did not adjust prior period financial information, which continue to reflect a presentation on a gross basis. 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% 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 (FX) 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 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 continue 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 are 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 sheet 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. Securities lending and borrowing 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, if such positions are not traded on an active exchange. > 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. 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. Loans Loans held at amortized cost Loans which the Group intends to hold until maturity are carried at outstanding principal balances, 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. For loans that have been restructured in a troubled debt restructuring, the applicable loan accounting depends on the loan classification. 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 at amortized cost, 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 amounts 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 loans with credit deterioration A purchased loan measured at amortized cost is considered a purchased loan with credit deterioration if it has experienced more-than-insignificant deterioration in credit quality since origination. At the date of acquisition, the allowance for credit is added to the purchase price of the loan to establish the initial amortized cost basis. Any difference between the amortized cost and the unpaid principal amount is recognized in interest income using the effective interest method. After the purchase date, the allowance for credit losses is adjusted for subsequent changes in estimates of current expected credit losses. 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 or additional ownership of 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 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 examinati

Summary of significant accounting policies	1 Summary of significant accounting policies Overview 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 credit 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. Certain accounting changes As noted in our 2021 Annual Report, the Bank identified an accounting issue that was not material to the prior period financial statements. The Bank identified this accounting issue with respect to the net balance sheet treatment relating to the presentation of a limited population of certain securities lending and borrowing activities. As a result, balance sheet and cash flow positions for both assets and liabilities relating to these activities were presented on a gross basis and prior periods were revised in the consolidated financial statements and the related notes. Beginning with the half-year ended June 30, 2022, the Bank has presented these securities lending and borrowing transactions as a single unit of account and as a result these transactions will no longer be presented on a gross basis. The Bank did not adjust prior period financial information, which continue to reflect a presentation on a gross basis. 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 SAB 121 – Accounting for Digital Asset Custodial Relationships In March 2022, the US Securities and Exchange Commission (SEC) published SEC Staff Accounting Bulletin (SAB) No. 121, “Accounting for Obligations to Safeguard Crypto-Assets an Entity Holds for Platform Users” (SAB 121). SAB 121 introduces interpretive guidance requiring the recognition of a liability and a corresponding asset to account for obligations to safeguard digital assets held for clients. SAB 121 requires additional disclosure of such custodial relationships in the interim and annual financial statements. The guidance within SAB 121 is effective for the interim and annual periods ending after June 15, 2022, with retrospective application to the beginning of the fiscal year. The adoption of SAB 121 did not have a material impact on the Group’s financial position, results of operations or cash flows. Standards to be adopted in future periods ASC Topic 326 – Financial Instruments – Credit Losses In March 2022, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2022-02, “Troubled Debt Restructurings and Vintage Disclosures” (ASU 2022-02), an update to ASC Topic 326 – Financial Instruments – Credit Losses. The amendments in ASU 2022-02 eliminate the accounting guidance for Troubled Debt Restructurings by creditors. The loan refinancing and restructuring guidance in ASC Topic 310 – Receivables will be applied to determine whether a modification results in a new loan or a continuation of an existing loan. The amendments enhance disclosure requirements for certain loan refinancings and restructurings when a borrower is experiencing financial difficulty and require disclosure of current period gross write-offs by year of origination for financing receivables and net investments in leases. The amendments are effective for annual reporting periods beginning after December 15, 2022 and for the interim periods within those annual reporting periods. Early adoption is permitted, including in an interim period. The adoption of ASU 2022-02 on January 1, 2023, applying the modified retrospective approach did not have a material impact on the Group’s financial position, results of operations or cash flows. ASC Topic 820 – Fair Value Measurement In June 2022, the FASB issued ASU 2022-03, “Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions” (ASU 2022-03), an update to ASC Topic 820 – Fair Value Measurement. The amendments in ASU 2022-03 clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. The amendments clarify that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction. The amendments require new disclosures related to equity securities subject to contractual sale restrictions, including the fair value of such equity securities, the nature and remaining duration of the corresponding restrictions and any circumstances that could cause a lapse in the restrictions. The amendments are effective for annual reporting periods beginning after December 15, 2023 and for the interim periods within those annual reporting periods. Early adoption is permitted, including in an interim period. The Group is currently evaluating the impact of the adoption of ASU 2022-03 on the Group’s financial position, results of operations and cash flows.

The transformation is intended to be funded through divestments, exits, capital actions and existing resources. As the Group implements these actions, restructuring costs, including from asset impairments and liability valuations, are expected to arise in connection with business activities the Group plans to exit or transfer and their related infrastructure. Effective January 1, 2023, reflecting the strategic announcement of October 27, 2022, the Group is organized into five divisions – Wealth Management, Swiss Bank, Asset Management and the Investment Bank, as well as a new Capital Release Unit (CRU). Beginning in the first quarter of 2023, the Group’s financial reporting will be presented accordingly. Core results include the results of the divisions and the Corporate Center and exclude the results of the CRU. Capital increase On November 23, 2022, Credit Suisse Group AG held an Extraordinary General Meeting, at which shareholders approved two capital increases. Credit Suisse Group AG completed the first capital increase on November 25, 2022 by way of a share placement of 462,041,884 newly issued shares to qualified investors resulting in gross proceeds of CHF 1.76 billion. Credit Suisse Group AG completed the second capital increase by way of a rights offering on December 9, 2022. By the end of the rights exercise period, 98.2% Liquidity issues in the fourth quarter of 2022 As previously disclosed, during early fourth quarter of 2022, Credit Suisse began experiencing significantly higher withdrawals of cash deposits as well as non-renewal of maturing time deposits. However, as the quarter progressed, these outflows stabilized to much lower levels but had not yet reversed by year end, and customer deposits declined by CHF 138 billion in the fourth quarter of 2022. As is normal practice, the Group also limited its access to the capital markets in the period immediately preceding the Group’s strategy announcements on October 27, 2022. Outflows in assets under management in the fourth quarter of 2022 As previously disclosed, Credit Suisse began experiencing deposit and net asset outflows in early fourth quarter of 2022 at levels that substantially exceeded the rates incurred in the third quarter of 2022. At the Group level, net asset outflows in the fourth quarter of 2022 were approximately 8% > Refer to “Note 39 – Assets under management” for further information. Sale of CS Trust business On September 6, 2022, the Group signed separate agreements with The Bank of N.T. Butterfield & Son Limited (Butterfield) and Gasser Partner Trust reg.

Segment information

Segment information	12 Months Ended
	Dec. 31, 2022
Segment information	4 Segment information The Group is a global financial services company domiciled in Switzerland and, effective January 1, 2022 until December 31, 2022, was organized into four divisions – Wealth Management, Investment Bank, Swiss Bank and Asset Management. Prior periods were restated to conform to the current presentation. > Refer to “Note 3 – Business developments, significant shareholders and subsequent events” for further information on the Group’s divisional organization effective January 1, 2023. 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: ■ Wealth Management ■ Investment Bank ■ Swiss Bank ■ Asset Management Corporate Center included parent company operations such as Group financing, expenses for projects sponsored by the Group and certain expenses and revenues that had not been allocated to the segments. In addition, the Corporate Center included 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, 2022
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 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.

There were no material net impairment losses on contract receivables in 2022, 2021 or 2020. The Group did not recognize any contract assets during 2022, 2021 or 2020. 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.

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) PD, (ii) LGD and (iii) 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 (A-IRB) 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. Internal credit ratings form a significant input to the model derived CECL PDs. For the majority of counterparties, internal credit ratings are determined via statistical rating models, which are developed under the A-IRB approach of the Basel framework. The models are tailored to the specific business of the respective obligor and are intended to reflect the risk of default over a one-year period of each counterparty. The Group has received approval from its primary regulator to use, and has fully implemented, the A-IRB approach. 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 ability to forecast credit losses over the reasonable and supportable period is based on the ability to forecast economic activity over a reasonable and supportable time window. 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. In the downside and upside scenarios, mean reversion to the base case projected paths will commence in year three, with full convergence occurring in years four and five for certain macroeconomic 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 amounts of expected credit losses. 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 the recovery management function, 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 loss is measured using (i) the present value of estimated future cash flows discounted at the contractual interest rate of the loan and (ii) the fair market value of collateral where the loan is collateral-dependent. 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 trends. The scenario design team within the Group’s Enterprise Risk Management (ERM) function determines the macroeconomic factors (MEFs) and market projections that are relevant for the Group’s three scenarios across the overall credit portfolio subject to the CECL accounting guidance. The scenario design team formulates the baseline scenario projections used for the calculation of expected credit losses 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 expected credit losses are approved by the Senior Management Approval Committee. Current-period estimate of expected credit losses on non-impaired credit exposures One of the most significant judgments involved in estimating the Group’s allowance for credit losses relates to the macroeconomic forecasts used to estimate credit losses over the forecast period, with modeled credit losses being driven primarily by a set of 37 MEFs. 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 industrial production growth rates. These MEFs are used in the portfolio- and region-specific CECL models and have been selected based on statistical criteria and expert judgment to explain expected credit losses. The table “Selected macroeconomic factors” includes the Group’s forecast of selected MEFs for 2023 and 2024, as estimated as of December 31, 2022. The comparative information includes the forecast of MEFs selected and estimated as of December 31, 2021. As of December 31, 2022, the forecast macroeconomic scenarios were weighted 50% 40% 10% Selected macroeconomic factors Forecast Forecast US real GDP growth rate (%) Downside (1.7) 0.5 Baseline 0.9 1.5 Upside 1.2 2.0 World industrial production (%) Downside (6.8) 0.4 Baseline 1.2 1.9 Upside 3.9 3.9 China real GDP growth rate (%) Downside (0.9) 2.1 Baseline 4.5 4.9 Upside 6.2 5.8 EU nominal GDP growth rate (%) Downside 3.4 2.3 Baseline 5.2 4.1 Upside 5.5 3.8 Swiss nominal GDP growth rate (%) Downside 0.0 1.0 Baseline 2.7 2.0 Upside 3.2 2.1 Forecasts represent the four-quarter average estimate of the respective macroeconomic factor as determined at the end of each reporting period.

Expected credit losses are not solely derived from MEF projections. Model overlays based on expert judgment are also applied, considering historical loss experience and industry and counterparty reviews, and primarily impacting certain corporate and institutional loans portfolios. Such overlays are designed to address circumstances where in management’s judgment the CECL model outputs are overly sensitive to the effect of economic inputs that exhibit significant deviation from their long-term historical averages. Overlays may also be used to capture judgment on the economic uncertainty from global or regional developments with severe impacts on economies. The Group’s non-specific allowance for expected credit losses on balance sheet and off-balance sheet credit exposures as of December 31, 2022 decreased compared to December 31, 2021. Model overlays were recalibrated during the year to take into account updated input elements based on expert judgment which led to a release. This release of overlays was outweighing the impact of additional stress from macroeconomic factors observable during the year. Overlays continued to be closely aligned with the macroeconomic forecasts and associated scenario weightings. 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. 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.

Gross write-offs of CHF 181 million in 2022 compared to gross write-offs of CHF 297 million in 2021 and were primarily related to corporate & institutional loans in both years. In 2022, gross write-offs in corporate & institutional loans reflected the sale of a facility relating to a coal mining company and write-offs of a loan to a consulting services company, an exposure to a financial institution impacted by sanctions imposed in connection with Russia’s invasion of Ukraine and individual positions in small and medium-sized enterprises, Swiss large corporates and ship finance. Write-offs in consumer loans were mainly related to Swiss consumer finance loans and a European mortgage. In 2021, gross write-offs in corporate & institutional loans were mainly related to positions in commodity trade finance, ship finance, corporate lending, the sale of a real estate-related loan and a position in the US health care sector. Write-offs in consumer loans were mainly related to consumer finance.

Debt securities held-to-maturity In 2022, the Group purchased foreign government debt securities held-to-maturity amounting to CHF 971 million, all related to a portfolio of US Treasury securities. The Group’s debt securities held-to-maturity with a carrying value of CHF 921 million as of December 31, 2022 represent a portfolio of US Treasury securities, all rated “AAA” based on the Group’s internal counterparty rating. US Treasury securities have a history of no credit losses and market price movements mainly reflect changes in market interest rates. Based on this history of no credit losses and the Group’s view of the current and forecasted economic environment, the Group expects the risk of non-payment for US Treasuries to be zero and does not have an allowance for credit losses for these securities. The credit quality of these securities is monitored on an ongoing basis and the Group’s zero-loss expectation is validated on at least a quarterly basis through the Group’s governance structure involving the Credit Risk and Treasury functions. > Refer to “Note 17 – Investment securities” for further information. Other financial assets The Group’s other financial assets include certain balance sheet positions held at amortized cost, each representing its own portfolio segment. They have the following risk characteristics: ■ ■ ■ ■ Allowance for credit losses – other financial assets held at amortized cost 2022 2021 2020 Allowance for credit losses (CHF million) Balance at beginning of period 4,216 55 45 Current-period provision for expected credit losses (132) 4,291 24 Gross write-offs (8) (9) (12) Recoveries 0 0 2 Net write-offs (8) (9) (10) Foreign currency translation impact and other adjustments, net 45 (121) (4) Balance at end of period 4,121 4,216 55 of which individually evaluated 4,099 4,202 17 of which collectively evaluated 22 14 38 The current-period provision for expected credit losses on other financial assets held at amortized cost included a release of CHF 155 million in 2022 and a provision of CHF 4,307 million in 2021 related to Archegos Capital Management (Archegos). As of December 31, 2022 and 2021, the allowance for credit losses on brokerage receivables of CHF 4,081 million and CHF 4,186 million, respectively, were primarily related to Archegos. In 2022 and 2021, the Group purchased other financial assets held at amortized cost amounting to CHF 931 million and CHF 196 million, respectively, primarily related to mortgage servicing advances. Credit quality information Monitoring of credit quality and internal ratings – Overview The Group monitors the credit quality of financial assets held at amortized cost through its credit risk management framework, which provides for the consistent evaluation, measurement and management of credit risk across the Group. Assessments of credit risk exposures for internal risk estimates and risk-weighted assets are calculated based on PD, LGD and EAD models. > Refer to “Expected credit losses on non-impaired credit exposures” for further information on PD, LGD and EAD. The credit risk management framework incorporates the following core elements: ■ ■ ■ ■ In addition to traditional credit exposure measurement, monitoring and management using current and potential future exposure metrics, Credit Risk performs counterparty and portfolio credit risk assessments of the impact of various internal stress test scenarios. Credit Risk assesses the impact to credit risk exposures arising from market movements in accordance with the scenario narrative, which can further support the identification of concentration or tail risks. The scenario suite includes historical scenarios as well as forward-looking scenarios which are used across the Risk function. Credit Risk evaluates and assesses counterparties and clients to whom the Group has credit exposures, primarily using internal rating models. Credit Risk uses these models to determine internal credit ratings which are intended to reflect the PD of each counterparty. For a majority of counterparties and clients, internal ratings are based on internally developed statistical models that have been backtested against internal experience and validated by a function independent of model development. Findings from backtesting serve as a key input for any future rating model developments. The Group’s internally developed statistical rating models are based on a combination of quantitative factors (e.g., financial fundamentals, such as balance sheet information for corporates and loan-to-value (LTV) ratio and the borrower’s income level for mortgage lending, and market data) and qualitative factors (e.g., credit histories from credit reporting bureaus and economic trends). For the remaining counterparties where statistical rating models are not used, internal credit ratings are assigned on the basis of a structured expert approach using a variety of inputs, such as peer analyses, industry comparisons, external ratings and research as well as the judgment of senior credit officers. In addition to counterparty ratings, Credit Risk also assesses the risk profile of individual transactions and assigns transaction ratings which reflect specific contractual terms such as seniority, security and collateral. Internal credit ratings may differ from external credit ratings, where available, and are subject to periodic review depending on exposure type, client segment, collateral or event-driven developments. The Group’s internal ratings are mapped to a PD band associated with each rating which is calibrated to historical default experience using internal data and external data sources. The Group’s internal rating bands are reviewed on an annual basis with reference to extended historical default data and are therefore based on stable long-run averages. Adjustments to PD bands are only made where significant deviations to existing values are detected. The last update was made in 2012 and since then no significant changes to the robust long-run averages have been detected. For the purpose of the credit quality disclosures included in these financial statements, an equivalent rating based on the Standard & Poor’s rating scale is assigned to the Group’s internal ratings based on the PD band associated with each rating. These internal ratings are used consistently across all classes of financial assets and are aggregated to the credit quality indicators “investment grade” and “non-investment grade”. The Group uses internal rating methodologies consistently for the purposes of approval, establishment and monitoring of credit limits and credit portfolio management, credit policy, management reporting, risk-adjusted performance measurement, economic risk capital measurement and allocation and financial accounting. A credit quality monitoring process is performed to provide for early identification of possible changes in the creditworthiness of clients and includes regular asset and collateral quality reviews, business and financial statement analysis and relevant economic and industry studies. Credit Risk maintains regularly updated watch lists and holds review meetings to re-assess counterparties that could be subject to adverse changes in creditworthiness. The review of the credit quality of clients and counterparties does not depend on the accounting treatment of the asset or commitment. > Refer to “Expected credit losses on impaired credit exposures” for further information on credit monitoring.

Debt securities held-to-maturity In 2022, the Bank purchased foreign government debt securities held-to-maturity amounting to CHF 971 million, all related to a portfolio of US Treasury securities. The Bank’s debt securities held-to-maturity with a carrying value of CHF 921 million as of December 31, 2022 represent a portfolio of US Treasury securities, all rated “AAA” based on the Bank’s internal counterparty rating. US Treasury securities have a history of no credit losses and market price movements mainly reflect changes in market interest rates. Based on this history of no credit losses and the Bank’s view of the current and forecasted economic environment, the Bank expects the risk of non-payment for US Treasuries to be zero and does not have an allowance for credit losses for these securities. The credit quality of these securities is monitored on an ongoing basis and the Bank’s zero-loss expectation is validated on at least a quarterly basis through the Bank’s governance structure involving the Credit Risk and Treasury functions. > Refer to “Note 16 – Investment securities” for further information.

In accordance with US GAAP, the Group continually assesses whether or not there has been a triggering event requiring a review of goodwill. Subsequent to the creation of the new segment structure, effective January 1, 2022, a portion of the Wealth Management business was transferred to the Investment Bank in the second quarter of 2022. Goodwill is reallocated between reporting units on a relative fair value basis. The Group concluded that the goodwill transferred to the Investment Bank reporting unit of CHF 23 million was fully impaired. The announcement on October 27, 2022 of the strategy and organizational changes as well as adverse market and economic conditions represent triggering events for the third quarter of 2022 for goodwill impairment testing purposes, and under US GAAP, goodwill has to be tested for impairment both before and immediately after a reorganization of reporting units. The review of the Group’s five-year financial plan to reflect the announced strategy was finalized in the fourth quarter of 2022. The Group concluded that the estimated fair value for all of the reporting units with goodwill exceeded their related carrying values and no further impairment was necessary as of December 31, 2022. The fair values of the Asset Management and Wealth Management reporting units both exceeded their related carrying values by less than 10% As a result of the announced strategy and organizational changes, the Private Fund Group business in the Asset Management reporting unit was transferred to the Investment Bank reporting unit effective January 1, 2023, resulting in an initial transfer of approximately CHF 30 million of goodwill between the reporting units. The Group expects a full impairment in the first quarter of 2023 of the goodwill transferred to the Investment Bank. As a result of the previously announced acquisition of The Klein Group LLC that is expected to close in the first half of 2023, the Investment Bank will initially recognize a goodwill balance of approximately CHF 60 million, which it expects to fully impair upon the closing of the acquisition. 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. The residual value between the total of these elements and the Group’s shareholders’ equity is allocated to the carrying value of 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 is given to price to projected earnings multiples and 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 is 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. Estimates of the Group’s future earnings potential, and that of the reporting units, involve considerable judgment, including management’s view on future changes in market cycles, the regulatory environment and the anticipated result of the implementation of business strategies, competitive factors and assumptions concerning the retention of key employees. 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.

Leases	24 Leases The Group enters into both lessee and lessor arrangements. > Refer to “Note 1 – Summary of significant accounting policies” and “Note 23 – Other assets and other liabilities” for further information. 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 2022, the Group entered into 12 sale-leaseback transactions with lease terms ranging from 5 to 10 years. During 2021, the Group entered into 13 sale-leaseback transactions with lease terms ranging from 3 to 10 years. During 2020, the Group entered into one sale-leaseback transaction with a lease term of one year.

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. As of December 31, 2022 and 2021, the Group had approximately CHF 1.3 billion and CHF 1.1 billion, respectively, of residual value guarantees associated with lessor arrangements. The Group’s risk of loss relating to the residual value of leased assets is mitigated through contractual arrangements with manufactures or suppliers. Leased assets are also monitored through projections of the residual values at lease origination and periodic reviews of residual values.

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.

Offsetting of financial assets

Offsetting of financial assets and financial liabilities	12 Months Ended
	Dec. 31, 2022
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. The Group uses master netting agreements to mitigate counterparty credit risk in certain transactions, including derivative contracts and securities borrowed, lent and subject to repurchase 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 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, 2022 and December 31, 2021. In certain circumstances, financial collateral received may be restricted during the term of the agreement (e.g., in tri-party arrangements).

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.

The movement also reflected tax impacts directly recorded in other comprehensive income, mainly related to own credit movements, partially offset by the impact of foreign exchange translation gains, which were included within the currency translation adjustments, and a pension plan re-measurement. The Group’s valuation allowance against gross deferred tax assets was CHF 10.2 billion as of December 31, 2022 compared to CHF 6.1 billion as of December 31, 2021. This was due to the uncertainty concerning the Group’s ability to generate the necessary amount and mix of taxable income in future periods. The valuation allowance also reflected an increase due to participation impairments in one of the Group’s operating entities in Switzerland and a decrease due to valuation allowance adjustments recorded in other comprehensive income, mainly related to own credit movements. Unrecognized deferred tax liabilities As of December 31, 2022, the Group had accumulated undistributed earnings from foreign subsidiaries of CHF 18.2 billion. No deferred tax liability was recorded in respect of those amounts, as these earnings are considered indefinitely reinvested. The Group would need to accrue and pay taxes on these undistributed earnings if such earnings were repatriated. It is not practicable to estimate the amount of unrecognized deferred tax liabilities for these undistributed foreign earnings.

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. Based on the expected future results in two of the Group’s operating entities in Switzerland and given that the Swiss tax law allows for a seven-year carry-forward period for NOLs, a valuation allowance is still required on the deferred tax assets of these entities. UK tax law allows for an unlimited carry-forward for NOLs, while US tax law allows for a 20-year carry-forward period for NOLs arising prior to 2017, federal NOLs generated in tax years from 2018, 2019 and 2020 to be carried back for five years and no expiry limitations for NOLs that arose in 2018 and subsequent years. However, unlimited and long expiry limitations for NOLs are not expected to have a material impact on the recoverability of the net deferred tax assets as management concluded that there was limited recoverability of the net deferred tax assets in the US and the UK as a result of the comprehensive strategic review announced on October 27, 2022, primarily due to limited future taxable income against which deferred tax assets could be utilized. Tax benefits associated with share-based compensation in 2022 2021 2020 Tax benefits (CHF million) Tax benefits recorded in the consolidated statements of operations 1 221 234 264 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, Germany, Switzerland, the UK and the US. 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 14 million in unrecognized tax benefits within 12 months of the reporting date. The Group remains open to examination from federal, state, provincial or similar local jurisdictions from the following years onward in these major countries: Switzerland – 2020 (federal and Zurich cantonal level); Brazil – 2017; the UK – 2012; and the US – 2010.

Employee deferred compensation

Employee deferred compensation	12 Months Ended
	Dec. 31, 2022
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. Replacement awards granted as part of a contractual obligation are 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. The Group fully covered its share delivery obligations through market purchases in 2022, 2021 and 2020. 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. Deferred compensation expense The following tables show the compensation expense for deferred compensation awards granted in 2022 and prior years that was recognized in the consolidated statements of operations during 2022, 2021 and 2020, the total shares delivered, the estimated unrecognized compensation expense for deferred compensation awards granted in 2022 and prior years outstanding as of December 31, 2022 and the remaining requisite service period over which the estimated unrecognized compensation expense will be recognized. The recognition of compensation expense for the deferred compensation awards granted in February 2023 began in 2023 and thus had no impact on the 2022 consolidated financial statements.

Share awards Deferred compensation awards are awarded to employees with total compensation of CHF/USD 250,000 or the local currency equivalent or higher. 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 material risk takers (MRTs), risk manager MRTs or senior managers or equivalents under the requirements of EU Capital Requirements Directive V and UK Investment Firms Prudential Regime. Share awards granted to MRTs vest over four years with one quarter of the award vesting on each of the four anniversaries of the grant date. Share awards granted to risk manager MRTs vest over five years with one fifth of the award vesting on each of the five anniversaries of the grant date. Share awards granted to senior managers vest over seven years, 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 In order to comply with the requirements of EU Capital Requirements Directive V and UK Investment Firms Prudential Regime and other applicable remuneration regulations, 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 either six months or one year from the date of grant, depending on the location.

The number of deferred share-based awards held by each individual was increased by 5.64%. The terms and conditions of the adjusted shares were the same as the existing share-based awards, thereby ensuring that holders of the awards were neither advantaged nor disadvantaged by the additional shares granted. Performance share awards Performance share awards will no longer be used as a form of deferred compensation award for the 2022 performance year and onwards. In prior years, 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, are subject to performance-based malus provisions. Outstanding performance share awards granted for prior years are subject to a downward adjustment in the event of a divisional loss by the division in which the employees worked as of December 31, 2022, or a negative ROE of the Group, whichever results in a larger adjustment. For employees in corporate functions and the Asset Resolution Unit, the downward 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. A downward adjustment has been applied to outstanding performance share awards, reflecting the negative Group ROE and full year divisional loss in the Investment Bank for 2022.

The number of deferred share-based awards held by each individual was increased by 5.64%. The terms and conditions of the adjusted shares were the same as the existing share-based awards, thereby ensuring that holders of the awards were neither advantaged nor disadvantaged by the additional performance shares granted. 2 Included downward adjustment applied to outstanding performance share awards. Strategic Delivery Plan The Strategic Delivery Plan (SDP) was a one-time share-based award granted in February 2022 to most managing directors and directors to incentivize the longer-term delivery of the Group’s strategic plan. SDP awards are subject to service conditions and performance-based metrics over the course of 2022-2024. SDP awards are scheduled to vest on the third anniversary of the grant date, with the exception of awards granted to individuals classified as MRTs, risk manager MRTs or senior managers or equivalents under the requirements of EU Capital Requirements Directive V and UK Investment Firms Prudential Regime. SDP awards granted to MRTs vest in equal annual installments over two years, commencing on the third anniversary from the grant date. SDP awards granted to risk manager MRTs vest in equal annual installments over three years, while SDP awards granted to senior managers vest in equal annual installments over five years, both commencing on the third anniversary from the grant date. Prior to settlement, the principal amount of the SDP awards will be written down to zero and forfeited if any of the following triggering events exist at the end of 2022, 2023 or 2024: ■ ■ In addition, the Compensation Committee will review and assess the overall success of the delivery of the strategic plan at a Group level over the three-year period (2022-2024) and may increase the SDP awards up to a maximum of 50% of the initial award amount. Half of the potential uplift would be granted if a pre-determined average Group return on tangible equity threshold is achieved, measured over 2023 and 2024. The other half of the uplift may be awarded based on the Compensation Committee’s assessment of risk management and other strategic non-financial achievements.

The terms and conditions of the adjusted shares were the same as the existing share-based awards, thereby ensuring that holders of the awards were neither advantaged nor disadvantaged by the additional Strategic Delivery Plan shares granted. Contingent Capital Awards Contingent Capital Awards (CCA) will no longer be used as a form of deferred compensation award for the 2022 performance year and onwards. The Group granted CCA of CHF 75 million and CHF 253 million in 2022 and 2021, respectively, to managing directors and directors as part of the 2021 and 2020 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 MRTs, risk manager MRTs or senior managers or equivalents under the requirements of EU Capital Requirements Directive V and UK Investment Firms Prudential Regime. CCA granted to MRTs, risk manager MRTs and senior managers vest on the fourth, fifth and seventh anniversaries of the grant date, respectively. CCA awards 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 2022 and 2021 that vest four five ■ ■ 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. 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: ■ ■ Cash awards 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 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 2022, 2021 and 2020 of CHF 294 million, CHF 259 million and CHF 120 million, respectively, in the Investment Bank, Wealth Management and Asset Management divisions. This compensation has been expensed over a three-year vesting period from the grant date. Amortization of this compensation in 2022 totaled CHF 214 million, of which CHF 125 million was related to awards granted in 2022. Upfront cash awards The Group granted upfront cash awards (UCA) of CHF 799 million and CHF 59 million in 2022 and 2021, 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 2022 totaled CHF 387 million, of which CHF 355 million was related to awards granted in 2022. Retention awards The Group granted deferred cash and share retention awards during 2022 of CHF 367 million, mainly in the Investment Bank division. During 2021 and 2020, the Group granted deferred cash and share retention awards of CHF 395 million and CHF 40 million, respectively. These awards are expensed over the applicable vesting period from the grant date.

Awards granted for the compensation year 2022 Share awards On February 10, 2023, the Group granted 102.8 million share awards with a total value of CHF 288 million. The estimated unrecognized compensation expense of CHF 262 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. The majority of share awards granted include the right to receive dividend equivalents on vested shares. 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 February 23, 2023. The fair value of each share award was CHF 2.87, the Group share price on the grant date.

Awards granted in 2023 Transformation Awards In February 2023, the Group granted Transformation Awards, with a total award value of CHF 350 million, to employees identified as being critical to the delivery of the transformation strategy. Of the total award value, CHF 70 million relates to the Executive Board and is subject to approval at the AGM 2023. For employees other than the Executive Board, the Transformation Award was granted in the form of both a deferred cash award and a deferred share award subject to performance conditions. For Executive Board members, the Transformation Award, subject to shareholder approval, was granted as 100% in the form of a deferred shares. Transformation Awards are expensed over the service period of the award. Transformation cash awards vest over two years with one half of the cash awards vesting on each of first and second anniversaries of the grant date (ratable vesting), with the exception of awards granted to individuals classified as MRTs, risk manager MRTs or senior managers or equivalents under the requirements of EU Capital Requirements Directive V and UK Investment Firms Prudential Regime. Transformation Awards granted to MRTs vest over four years with one quarter of the award vesting on each of the four anniversaries of the grant date. Transformation Awards granted to risk manager MRTs vest over five years with one fifth of the award vesting on each of the five anniversaries of the grant date. Transformation Awards granted to senior managers vest over seven years, with one fifth of the award vesting on each of the third to seventh anniversaries of the grant date. Transformation share-based awards are scheduled to vest if the share price is at CHF 3.82 or higher on December 31, 2025, subject to a cap of three times the initial award grant value. This is applied after taking into account the performance targets, the reported return on tangible equity and cost base for the Group. Other awards In the first quarter of 2023, the Group granted additional compensation awards to certain employees. Share-based awards of CHF 38 million and deferred fixed cash compensation of CHF 30 million were granted to key employees. These awards will be expensed over a three-year vesting period from the grant date.

The Group’s related parties include key management personnel, close family members of key management personnel and entities that are controlled, significantly influenced, or for which significant voting power is held, by key management personnel or their close family members. Key management personnel are those individuals having authority and responsibility for planning, directing and controlling the activities of the Group, that is, members of the Executive Board and the Board of Directors. Banking relationships The Group is a global financial services provider. Many of the members of the Executive Board and the Board of Directors, their close family members or companies associated with them maintain banking relationships with the Group. The Group or any of its banking subsidiaries may from time to time enter into financing and other banking agreements with companies in which current members of the Executive Board or the Board of Directors have a significant influence as defined by the SEC, such as holding executive and/or board level roles in these companies. With the exception of the transactions described below, relationships with members of the Executive Board or the Board of Directors and such companies were in the ordinary course of business and are entered into at prevailing market conditions. Also, unless otherwise noted, all loans to members of the Executive Board, members of the Board of Directors, their close family members or companies associated with them were made in the ordinary course of business, were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other persons and did not involve more than the normal risk of collectability or present other unfavorable features. As of December 31, 2022, 2021 and 2020, there were no loan exposures to such related parties that were not made in the ordinary course of business and at prevailing market conditions. CS First Boston On February 9, 2023, the Group announced that it had taken further important steps to progress the carve-out of CS First Boston as a leading capital markets and advisory business through the acquisition of The Klein Group LLC, the investment banking business as well as the registered broker-dealer of M. Klein & Company LLC (the seller). The Group also announced the appointment of former Board of Directors member Michael Klein as CEO of Banking and regional CEO of Americas, as well as designated CEO of CS First Boston and a member of the Executive Board. Both Michael Klein’s appointment to the Executive Board and the acquisition of The Klein Group LLC are subject to regulatory approval. The purchase price is USD 175 million. To align interests with the Group, the seller will receive a convertible note and a warrant. The note will provide annual payments and convert into, and the warrant entitles the seller to subscribe to, CS First Boston shares at a qualified IPO or other liquidity event, at the then-valuation of CS First Boston, less a customary discount. The principal amount of the convertible note is expected to be USD 100 million, with the balance being paid in cash, dependent on the amount of taxes to be paid by the seller at closing. The net present value of the transaction to the Group is expected to be approximately USD 210 million, which also includes interest cost, annual payments on the note and other payments that may in the future become payable in respect of this transaction. Deutsche Bank AG provided a fairness opinion to the Board of Directors in connection with the acquisition. The transaction is expected to close in the first half of 2023. Following the acquisition’s closing, The Klein Group LLC is expected to be fully integrated into CS First Boston. The Group will retain control over the ultimate scope and structure of CS First Boston, including options to attract third-party capital in the future, as announced at the strategy update on October 27, 2022. In addition, on October 27, 2022, the Group and The Klein Group LLC entered into an engagement letter, under which The Klein Group LLC has been engaged to provide strategic advice and assistance to the Group in connection with the proposed carve-out of CS First Boston, whereby it was agreed that Michael Klein would devote significant time and attention to the services to be provided by The Klein Group LLC to the Group. The purpose of this engagement was to secure Michael Klein’s services in relation to the establishment of CS First Boston in the time gap between October 27, 2022 and the effective date of his employment contract as a member of the Executive Board (which is contingent on regulatory approval) and to obtain the support of The Klein Group LLC until closing of the acquisition. The advisory fee under such engagement was USD 10 million. 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.

Pension and other post-retireme

Pension and other post-retirement benefits	12 Months Ended

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 2022, 2021 and 2020, the Group contributed to these plans and recognized as expense CHF 241 million, CHF 263 million and CHF 299 million, respectively. This includes expenses of CHF 81 million, CHF 100 million and CHF 143 million in 2022, 2021 and 2020, respectively, related to the Swiss defined contribution pension plan which took effect on January 1, 2020. Contributions to the Swiss defined contribution plan are made by employees and the Group. Assets from this plan are paid out as a lump sum on retirement. 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. The Swiss pension plan 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, 2022 and 2021, the Swiss pension plan comprised 62% 64% 88% 84% 87% 84% 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 eight 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 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 2022, 2021 and 2020 were CHF 259 million, CHF 240 million and CHF 218 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 11 million in 2022, curtailment losses of CHF 2 million in 2021 and curtailment gains of CHF 10 million in 2020. Additional costs of CHF 6 million, CHF 10 million and CHF 8 million in 2022, 2021 and 2020, 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 7 million, CHF 16 million and CHF 8 million have been recognized in 2022, 2021 and 2020, 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 2022 and 2021, 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 net amount recognized in the consolidated balance sheets as of December 31, 2022 and 2021 for the defined benefit pension plans was an overfunding of CHF 3,965 million and CHF 4,011 million, respectively. The remeasurement loss on the Swiss pension plan recorded as of December 31, 2022 consisted of losses on the asset portfolio of CHF 2,004 million, partially offset by gains on the PBO of CHF 1,975 million due to changes in financial and demographic assumptions, primarily an increase in the discount rate. The remeasurement gain on the Swiss pension plan recorded as of December 31, 2021 consisted of gains on the asset portfolio of CHF 1,189 million, partially offset by losses on the PBO of CHF 321 million due to changes in financial and demographic assumptions, primarily an increase in the interest rate on savings balances. The remeasurement loss on the international pension plans recorded as of December 31, 2022 consisted of losses on the asset portfolio of CHF 1,199 million, partially offset by gains on the PBO of CHF 907 million due to changes in financial and demographic assumptions, primarily an increase in the discount rate and updates on the membership data. The remeasurement loss on the international pension plans recorded as of December 31, 2021 consisted of losses on the asset portfolio of CHF 110 million, partially offset by gains on the PBO of CHF 100 million due to changes in financial and demographic assumptions, primarily an increase in the discount rate and updates on the membership data. The settlements of CHF 448 million on the international plans recorded as of December 31, 2021 mainly related to settlements in the UK, reflecting an enhanced transfer value exercise, and settlements in the US, reflecting a partial sale of pension obligations sold to a third party insurer. In 2023, the Group expects to contribute CHF 271 million to the Swiss pension plan, CHF 15 million to the international defined benefit pension plans and CHF 10 million to other post-retirement defined benefit plans.

Net periodic benefit cost and benefit obligation assumptions The assumptions used to determine the benefit obligation as of the measurement date are also used to calculate the net periodic benefit costs for the 12-month period following this date. 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. 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 is based on long-term expected returns, inflation, interest rates, risk premiums and the pension plan’s asset allocation. The estimates take into consideration historical asset category returns.

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 2022 2021 2020 Health care cost trend rate (%) Annual weighted-average health care cost trend rate 1 6.3 6.5 7.0 1 The annual health care cost trend rate is assumed to decrease gradually to achieve the long-term health care cost trend rate of 4.5% by 2030. The annual health care cost trend rate used to determine the net periodic defined benefit costs for 2023 is 6.3% 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 Swiss defined benefit pension plan employs a total return investment approach, whereby a diversified mix of debt and equity securities, real estate and alternative investments is used to maximize the long-term return of plan assets while incurring a prudent level of risk. The international plans employ asset liability matching strategies, where the portfolios are mostly invested in debt securities with maturity profiles similar to that of the pension plans’ expected future cash flows, with the aim of minimizing interest rate and inflation risk. Risk tolerance is established through careful consideration of plan liabilities, plan funded status and corporate financial conditions. Investment risk is measured and monitored on an ongoing basis through periodic asset/liability studies and investment portfolio reviews. As of December 31, 2022 and 2021, the total fair value of Group debt securities included in plan assets of the Group’s defined benefit pension plans was CHF 6 million and CHF 5 million, respectively, and the total fair value of Group equity securities and options was CHF 2 million and CHF 3 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, 2022 and 2021 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.

Bank
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 2022, 2021 and 2020, the Bank contributed to these plans and recognized as expense CHF 211 million, CHF 235 million and CHF 240 million, respectively. This included expenses of CHF 69 million, CHF 89 million and CHF 96 million in 2022, 2021 and 2020, respectively, related to the Swiss defined contribution pension plan which took effect on January 1, 2020. Contributions to the Swiss defined contribution plan are made by employees and the Group. Assets from this plan are paid out as a lump sum on retirement. 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 83% 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 2022, 2021 and 2020, the Bank contributed and recognized as expense CHF 215 million, CHF 248 million and CHF 249 million to the Group plan, respectively. The Bank expects to contribute CHF 225 million to the Group plan during 2023. 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.

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 2022 2021 2020 Health care cost trend rate (%) Annual weighted-average health care cost trend rate 1 6.3 6.5 7.0 1 The annual health care cost trend rate is assumed to decrease gradually to achieve the long-term health care cost trend rate of 4.5% by 2030.

Derivatives and hedging activit

Derivatives and hedging activities	12 Months Ended
	Dec. 31, 2022
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 mainly on mortgages, loans and reverse repurchase agreements 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 2022, 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 the maintenance of contractually specified credit ratings from each of the major credit rating agencies. If the ratings fall below the level specified in the contract, the counterparties to the agreement 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 the contractually specified credit ratings. 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 that could be called by counterparties in the event of a one, two or three-notch downgrade in the contractually specified credit ratings. 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.

Excludes contracts with specified conditions and clauses which, when triggered, would result in a receivable position for the Group. 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 5.9 billion and CHF 12.0 billion as of December 31, 2022 and 2021, 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 that could be called by counterparties in a one, two or three-notch downgrade in the contractually specified credit ratings. 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 5.9 billion and CHF 12.0 billion as of December 31, 2022 and 2021, 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, 2022
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 Maturity Maturity Maturity 1 2022 (CHF million) Credit guarantees and similar instruments 2,257 451 127 471 3,306 3,193 22 2,068 Performance guarantees and similar instruments 4,280 1,750 729 513 7,272 6,527 61 3,778 Derivatives 2 2,646 1,702 520 374 5,242 5,242 101 – Other guarantees 4,455 859 182 1,144 6,640 6,640 56 3,292 Total guarantees 13,638 4,762 1,558 2,502 22,460 21,602 240 9,138 2021 (CHF million) Credit guarantees and similar instruments 2,124 1,049 197 561 3,931 3,874 25 2,014 Performance guarantees and similar instruments 3,982 2,253 555 528 7,318 6,299 40 3,605 Derivatives 2 5,374 2,567 561 419 8,921 8,921 289 – Other guarantees 4,012 1,040 307 1,151 6,510 6,469 71 3,789 Total guarantees 15,492 6,909 1,620 2,659 26,680 25,563 425 9,408 1 Total net amount is computed as the gross amount less any participations. 2 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. 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 protected deposits in case of specified restrictions or compulsory liquidation of a deposit-taking bank. In Switzerland, deposit-taking banks and securities dealers jointly guaranteed an amount of up to CHF 6 billion under the regulation applicable until December 31, 2022. 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, 2022 to December 31, 2022 was CHF 0.5 billion. These deposit insurance guarantees were reflected in other guarantees. On January 1, 2023, a partial revision of the Swiss Federal Law on Banks and Savings Banks (Bank Law) became effective, which included changes to the Swiss deposit insurance guarantee program. Under the revised program, among other changes, the jointly guaranteed amount is now determined as the higher of CHF 6 billion or 1.6% 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. Depending on the details of the counterparty contract with Credit Suisse, both a counterparty’s existing funded reverse repurchase agreement and any forward reverse repurchase agreements under contract with the same counterparty are considered. Other commitments Other commitments include contracts that require the Group to make payments should a third party fail to do so under a specified future credit obligation, such as commitments arising from deferred payment letters of credit, e.g., with re-insurance clients. Other commitments also include private equity commitments, firm commitments in underwriting securities as well as commitments from acceptances in circulation and liabilities for call and put options on shares and other equity instruments.

Deposit-taking banks and securities dealers in Switzerland and certain other European countries are required to ensure the payout of protected deposits in case of specified restrictions or compulsory liquidation of a deposit-taking bank. In Switzerland, deposit-taking banks and securities dealers jointly guaranteed an amount of up to CHF 6 billion under the regulation applicable until December 31, 2022. Upon occurrence of a payout event triggered by a specified restriction of business imposed by the Swiss Financial Market Supervisory Authority FINMA (FINMA) or by the compulsory liquidation of another deposit-taking bank, the Bank’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 Bank, the Bank’s share in the deposit insurance guarantee program for the period July 1, 2022 to December 31, 2022 was CHF 0.5 billion.

Transfers of financial assets and variable interest entities	12 Months Ended

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. Since the Group generally accounts for assets pending transfer, i.e., prior to securitization, at fair value, the Group does not typically recognize significant gains or losses upon the transfer of assets. 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 2022, 2021 and 2020 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.

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 its underwriting and market-making activities, primarily reflecting risk retention requirements applicable to certain securitization 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 SPEs and the total assets of the SPEs as of December 31, 2022 and 2021, 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.

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. Transfers of financial assets where sale treatment was not achieved The following table provides the carrying amounts of transferred financial assets and the related liabilities where sale treatment was not achieved as of December 31, 2022 and 2021. > Refer to “Note 37 – Assets pledged and collateral” for further information.

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, 2022 and 2021.

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 249 days as of December 31, 2022, Alpine’s CP had exposures mainly in reverse repurchase agreements with a Group entity, solar loans and leases, consumer loans 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. In such circumstances, the Group may be viewed as the primary beneficiary of specified assets referenced under liquidity agreements, resulting in consolidation of specified assets, which are included as part of the consolidated VIEs table. 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 generally 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. As of December 31, 2022, certain liquidity facilities with third-party CP conduits referenced groups of specified assets and liabilities within a VIE for which the Group is the primary beneficiary which required consolidation. 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

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. Key economic assumptions at the time of transfer > Refer to “Note 35 – 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 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. Alpine is a separate legal entity that is wholly owned by the Bank. However, its assets are available to satisfy only the claims of its creditors. 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 249 days as of December 31, 2022. Alpine’s CP had exposures mainly in reverse repurchase agreements with a Bank entity, solar loans and leases, consumer loans 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. In such circumstances, the Bank may be viewed as the primary beneficiary of specified assets referenced under liquidity agreements, resulting in consolidation of specified assets, which are included as part of the consolidated VIEs table. 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 Bank reviews the credit risk associated with these transactions on the same basis that would apply to other extensions of credit. The Bank 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 Bank is not the primary beneficiary and generally does not consolidate these third-party CP conduits. The Bank’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 Bank 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. As of December 31, 2022, certain liquidity facilities with third-party CP conduits referenced groups of specified assets and liabilities within a VIE for which the Group is the primary beneficiary which required consolidation. 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 Bank reviews the credit risk associated with these transactions on the same basis that would apply to other extensions of credit. In some situations, the Bank can enter into liquidity facilities with these third-party CP conduits through Alpine. The Bank’s economic risks associated with the Alpine CP conduit and the third-party CP conduits are included in the Bank’s risk management framework including counterparty, economic risk capital and scenario analysis. Consolidated VIEs The Bank has significant involvement with VIEs in its role as a financial intermediary on behalf of clients. The Bank consolidates all VIEs related to financial intermediation for which it is the primary beneficiary.

Financial instruments

Financial instruments	12 Months Ended
	Dec. 31, 2022
Financial instruments	36 Financial instruments The disclosure of the Group’s financial instruments includes the following sections: ■ ■ ■ ■ Concentration 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 Executive Board Risk Management Committee and the Board’s 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 significant unobservable 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 OTC derivatives with observable inputs to valuation and are included in level 2 of the fair value hierarchy. If the significant inputs used to determine the fair value of the similar OTC derivative are 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, 2022
Capital adequacy	38 Capital adequacy The Group is subject to the Basel framework, as implemented in Switzerland, as well as Swiss legislation and regulations for systemically important banks, 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 framework in Switzerland in respect of capital requirements for systemically important banks, including Credit Suisse, goes beyond the Basel minimum standards for systemically important banks. 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 Credit Suisse, 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 (TLAC). The going concern and gone concern requirements are generally aligned with the Financial Stability Board’s total loss-absorbing capacity standard. 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. Additionally, there are FINMA decrees that apply to Credit Suisse 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 balance sheet 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, 2022 and 2021, 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, 2022 and 2021, 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 or distributable reserves. For holding companies, legal reserves may be distributed if they exceed, after deduction of any accumulated losses, treasury shares and reserves for own shares held by subsidiaries, 20% of the share capital registered in the commercial register. Furthermore, dividends may be paid out only after shareholder approval. As of December 31, 2022 and 2021, 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 2022 2021 CHF billion Assets in collective investment instruments managed by Credit Suisse 196.7 231.8 Assets with discretionary mandates 244.1 294.8 Other assets under management 852.8 1,087.4 Assets under management (including double counting) 1,293.6 1,614.0 of which double counting 32.1 46.2 Changes in assets under management 2022 2021 Assets under management (CHF billion) Balance at beginning of period 1 1,614.0 1,511.9 Net new assets/(net asset outflows) (123.2) 2 30.9 Market movements, interest, dividends and foreign exchange (170.0) 92.6 of which market movements, interest and dividends 3 (165.9) 80.8 of which foreign exchange (4.1) 11.8 Other effects (27.2) (21.4) Balance at end of period 1,293.6 1,614.0 1 Including double counting. 2 Refer to "Outflows in assets under management in the fourth quarter of 2022" in Note 3 - Business developments, significant shareholders and subsequent events for further information on net asset outflows. 3 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 Wealth Management and Swiss 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 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, 2022
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. This review includes consideration of management’s strategy for resolution of matters through settlement or trial, as well as changes in such strategy. 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 2022 CHF million Balance at beginning of period 1,539 Increase in litigation accruals 1,907 Decrease in litigation accruals (347) Decrease for settlements and other cash payments (1,999) Foreign exchange translation 72 Balance at end of period 1,172 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 1.2 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 certain levels of consumer relief measures, including affordable housing payments and loan forgiveness, 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. Credit Suisse continues to evaluate its approach toward satisfying its remaining consumer relief obligations in light of its business reassessment and anticipated related transactions, and Credit Suisse currently anticipates that it will take much longer than the five-year period provided in the settlement to satisfy in full its obligations in respect of these consumer relief measures and that it may only complete them by 2026 or later, subject to market conditions and the Group’s risk appetite. Credit Suisse expects to incur costs in relation to satisfying those obligations. The amount of consumer relief Credit Suisse must provide also increases after 2021 pursuant to the original settlement by 5% 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 complaint, which referenced approximately USD 10 billion of original unpaid principal balance across 13 RMBS issued, sponsored, deposited and underwritten by CSS LLC and its affiliates in 2006 and 2007, alleged that CSS LLC and its affiliates misled investors and engaged in fraud or deceit in connection with the offer and sale of RMBS, and sought an unspecified amount of damages. On October 25, 2022, following a settlement in the amount of USD 495 million, for which Credit Suisse was fully reserved, the SCNJ dismissed with prejudice all claims against CSS LLC and affiliated entities. 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 as an RMBS issuer, underwriter and/or other participant, along with other defendants, was named as a defendant in an action brought by the Federal Deposit Insurance Corporation (FDIC), as receiver for Colonial Bank, in the US District Court for the Southern District of New York (SDNY), in which claims against CSS LLC related to approximately USD 92 million of the RMBS at issue (approximately 23% In early March 2022, in an action brought by the FDIC, as receiver for Citizens National Bank and Strategic Capital Bank, in the SDNY, in which claims related to approximately USD 28 million of RMBS at issue, CSS LLC and its affiliates executed an agreement with the plaintiffs to settle and dismiss all claims against CSS LLC and its affiliates. CSS LLC and certain of its affiliates were 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 related to approximately USD 97 million of RMBS at issue. On April 12, 2022, the parties executed an agreement to settle and dismiss 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 in an amended complaint filed on August 19, 2019; 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 Appellate Division First Department of the SCNY (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; on March 17, 2022, the New York State Court of Appeals reversed the decision of the First Department and ordered that DLJ’s motion for partial summary judgment be granted; a non-jury trial in the action was held between January 23 and February 3, 2023, and a decision is pending; (iv) one action brought by Home Equity Asset Trust 2007-2, in which plaintiff alleges damages of not less than USD 495 million; and (v) 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 is also a defendant in one action brought by Home Equity Asset Trust Series 2007-3, in which plaintiff alleges damages of not less than USD 206 million. On March 5, 2022, DLJ and the plaintiffs executed an agreement to settle this action. The settlement remains subject to approval through a trust instruction proceeding brought in Minnesota state court by the trustee of the plaintiff trust. 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 April 19, 2021, DLJ, SPS and the plaintiffs executed an agreement to settle both actions for the aggregate amount of USD 500 million, for which Credit Suisse was fully reserved. The settlement remains subject to approval through a trust instruction proceeding brought in Minnesota state court by the trustee of the plaintiff trusts. Following the earlier dismissal of three consolidated repurchase actions in the SCNY in 2013 and the New York State Court of Appeals’ upholding of this dismissal in February 2019, 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 previously dismissed with prejudice in 2013. 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. On November 22, 2022, the plaintiffs withdrew their appeal to the First Department, such that the action is now fully dismissed. 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 and 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 April 24, 2020, the Texas Supreme Court issued a ruling reversing a portion of the trial court’s September 4, 2015 judgment related to the bench trial, 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 claims for fraudulent inducement by affirmative misrepresentation. The Texas Supreme Court subsequently remanded the case back to the trial court for further proceedings related to the calculation of damages and interest. On June 25, 2021, the trial court entered a new judgment, which awarded plaintiff a total of approximately USD 121 million. CSS LLC and its affiliates appealed the judgment. On February 14, 2023, the appeals court issued a ruling, reversing in favor of CSS LLC a portion of the trial court’s June 25, 2021 judgment related to secondary market purchases, concluding in favor of CSS LLC that the trial court erred by failing to apply certain settlement credits to the December 2014 jury award amount and remanding the case to the trial court to consider the amount of prejudgment interest owed to Highland. 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. 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. Credit Suisse Group AG, Credit Suisse AG and Credit Suisse Securities (Europe) Limited (CSSEL) received a Statement of Objections and a Supplemental Statement of Objections from the Commission on July 26, 2018 and March 19, 2021, respectively, alleging that Credit Suisse entities engaged in anticompetitive practices in connection with their foreign exchange trading business. On December 6, 2021, the Commission issued a formal decision imposing a fine of EUR 83.3 million. On February 15, 2022, Credit Suisse appealed this decision to the EU General Court. The reference rates investigations have also included information requests from regulators concerning supranational, sub-sovereign and agency (SSA) bonds and commodities markets. Credit Suisse Group AG and CSSEL received a Statement of Objections from the Commission on December 20, 2018, alleging that Credit Suisse entities engaged in anticompetitive practices in connection with their SSA bonds trading business. On April 28, 2021, the Commission issued a formal decision imposing a fine of EUR 11.9 million. On July 8, 2021, Credit Suisse appealed this decision to the EU General Court. Civil litigation USD LIBOR litigation Beginning in 2011, certain Credit Suisse entities were named in various putative class and individual 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. 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). After a number of putative class and individual plaintiffs appealed the dismissal of their antitrust claims to the United States Court of Appeals for the Second Circuit (Second Circuit), on December 30, 2021, the Second Circuit affirmed in part and reversed in part the district court’s decision and remanded the case to the SDNY. On September 21, 2021, in the putative class action brought in the multi-district litigation in the SDNY by holders of bonds tied to LIBOR, Credit Suisse entered into an agreement to settle all claims. On November 7, 2022, the court entered an order granting preliminary approval to the agreement to settle all claims. The settlement remains subject to final court approval. Separately, on February 4, 2022, three actions brought by individual plaintiffs, and on November 18, 2022, one additional individual action, were dismissed against Credit Suisse. On November 17, 2021, in the putative class action brought on behalf of those who lent at rates tied to LIBOR, Credit Suisse entered into an agreement to settle all claims. On March 11, 2022 and July 26, 2022, respectively, the SDNY entered orders granting preliminary and final approval to the agreement to settle all claims. Separately, on May 4, 2017, the plaintiffs in three 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. 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 March 26, 2020, the SDNY granted defendants’ motion to dismiss, and on February 14, 2022, the Second Circuit dismissed plaintiffs’ appeal of the SDNY’s decision granting defendants’ motion to dismiss. 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 December 23, 2021, the court denied plaintiffs’ motion for preliminary and permanent injunctions to enjoin panel banks from continuing to set LIBOR or automatically setting the benchmark to zero each day, and on September 13, 2022, the court granted defendants’ motions to dismiss. On October 4, 2022, plaintiffs filed an amended complaint. On November 4, 2022, defendants filed a motion to dismiss the amended complaint. 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. After defendants’ motion to dismiss for lack of subject matter jurisdiction was granted and plaintiffs successfully appealed, on July 13, 2022, Credit Suisse entered into an agreement to settle all claims. On February 15, 2023, the court entered an order granting preliminary approval to the agreement to settle all claims. The settlement remains subject to final court approval. 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. After defendants’ motion to dismiss for lack of subject matter jurisdiction was granted and plaintiffs successfully appealed, on April 22, 2022, Credit Suisse entered into an agreement to settle all claims. On June 9, 2022 and November 29, 2022, respectively, the court entered orders granting preliminary and final approval to the agreement to settle all claims. Foreign exchange litigation Credit Suisse Group AG and affiliates as well as other financial institutions have been named in civil lawsuits relating to the alleged manipulation of foreign exchange rates. The first pending matter is a consolidated class action. In that matter, on September 3, 2019, the SDNY denied plaintiffs’ motion for certification of a Rule 23(b)(3) damages class, ruling that proof of both injury and damages must proceed on an individual basis, but granted certification as to two threshold issues concerning the alleged conspiracy. The SDNY also denied plaintiffs’ motion for certification of a second proposed class in its entirety. On February 1, 2022, the SDNY denied the parties’ cross-motions for summary judgment. On April 22, 2022, Credit Suisse filed a motion to de-certify the issue class, which was denied on August 31, 2022. A jury trial was held in October 2022 on the issues of whether a conspiracy existed to manipulate bid-ask spreads in the FX market and whether Credit Suisse knowingly participated in any such conspiracy. On October 20, 2022, a verdict was issued in favor of Credit Suisse, finding that Credit Suisse did not knowingly participate in any such conspiracy. On November 10, 2022, plaintiffs moved for a new trial, which was denied on February 16, 2023. A second pending matter originally named Credit Suisse Group AG and affiliates, as well as other financial institutions, in a civil action filed in the SDNY on November 13, 2018. This action was based on the same alleged conduct as the consolidated class action. After the court granted in part and denied in part defendants’ motion to dismiss the second amended complaint, and plaintiffs filed a third amended complaint, on July 27, 2022, Credit Suisse entered into an agreement to settle all claims. On August 31, 2022, pursuant to the settlement agreement, the court dismissed with prejudice plaintiffs’ claims against Credit Suisse. Credit Suisse AG, together with other financial institutions, was also named in a consolidated putative class action in Israel, which made allegations similar to the consolidated class action. On April 4, 2022, Credit Suisse entered into an agreement to settle all claims. The settlement remains subject to court approval. Treasury markets litigation CSS LLC, along with over 20 other primary dealers of US treasury securities, was named in a number of putative civil class action complaints in the US relating to the US treasury markets. These complaints generally alleged that the defendants colluded to manipulate US treasury auctions, as well as the pricing of US treasury securities in the when-issued market, with impacts upon related futures and options. These actions were consolidated into a multi-district litigation in the SDNY. On November 15, 2017, plaintiffs filed a consolidated amended class action complaint containing the previously asserted allegations as well as new allegations concerning a group boycott to prevent the emergence of anonymous, all-to-all trading in the secondary market for treasury securities. On May 22, 2018, defendants filed motions to dismiss, which the SDNY granted on March 31, 2021. On May 14, 2021, plaintiffs filed an amended complaint. On August 4, 2021, defendants filed a motion to dismiss. On March 31, 2022, the SDNY granted defendants’ motion to dismiss and dismissed with prejudice all claims against the defendants. On April 28, 2022, plaintiffs filed a notice of appeal. SSA bonds litigation Credit Suisse Group AG and affiliates, along with other financial institutions and individuals, have been named in several putative class action complaints filed in the SDNY relating to SSA bonds. The complaints generally allege that defendants conspired to fix the prices of SSA bonds sold to and purchased from investors in the secondary market. These actions have been consolidated in the SDNY. On July 19, 2021, the Second Circuit affirmed the SDNY’s September 30, 2019 and March 18, 2020 decisions granting defendants’ motions to dismiss. On August 2, 2021, the plaintiffs filed a petition for rehearing en banc and panel rehearing, which the Second Circuit denied on September 2, 2021. On March 3, 2022, plaintiffs moved to vacate the dismissal of their case after the SDNY judge disc

Significant valuation and income recognition differences between US GAAP and Swiss GAAP banking law (true and fair view)	43 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 Accounting Ordinance (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. 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, equity securities where the company has no significant influence and which do not have a readily determinable fair value are measured in accordance with the NAV practical expedient, or by using the measurement alternative or at fair value. Under Swiss GAAP, investments in equity securities where the company has no significant influence and 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. 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, or by using the measurement alternative or at fair value. Under Swiss GAAP, non-marketable equity securities where the company has no intent to hold the securities permanently 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, the same impairment model and methodology is applied as under US GAAP. Differences between the two GAAPs result for items which are not measured at amortized cost under US GAAP and therefore not in scope of CECL under US GAAP, but that have to be measured at amortized cost under Swiss GAAP and are therefore in scope of CECL under Swiss GAAP. Such differences in CECL measurement mainly result from loans, irrevocable loan commitments and financial guarantees which are FVO elected under US GAAP and measured at amortized cost under Swiss GAAP. 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. Digital assets held in custody Under US GAAP, an entity records a liability on its balance sheet for its obligation to safeguard digital assets held as a custodian for its clients, and a corresponding safeguarding asset. Under Swiss GAAP, the recording of a safeguarding liability and a safeguarding asset for digital assets held as a custodian for its clients is not required. 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, 2022
Basis of presentation	Overview 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% 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.
Revisions of prior period financial statements, Policy [Text Block]	Certain accounting changes As noted in our 2021 Annual Report, the Group identified an accounting issue that was not material to the prior period financial statements. The Group identified this accounting issue with respect to the net balance sheet treatment relating to the presentation of a limited population of certain securities lending and borrowing activities. As a result, balance sheet and cash flow positions for both assets and liabilities relating to these activities were presented on a gross basis and prior periods were revised in the consolidated financial statements and the related notes. Beginning with the quarter ended June 30, 2022, the Group has presented these securities lending and borrowing transactions as a single unit of account and as a result these transactions will no longer be presented on a gross basis. The Group did not adjust prior period financial information, which continue to reflect a presentation on a gross basis.
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 (FX) 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 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 continue 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 are 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 sheet 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. Securities lending and borrowing 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, if such positions are not traded on an active exchange. > 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. 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.
Loans	Loans Loans held at amortized cost Loans which the Group intends to hold until maturity are carried at outstanding principal balances, 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. For loans that have been restructured in a troubled debt restructuring, the applicable loan accounting depends on the loan classification. 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 at amortized cost, 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 amounts 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 loans with credit deterioration A purchased loan measured at amortized cost is considered a purchased loan with credit deterioration if it has experienced more-than-insignificant deterioration in credit quality since origination. At the date of acquisition, the allowance for credit is added to the purchase price of the loan to establish the initial amortized cost basis. Any difference between the amortized cost and the unpaid principal amount is recognized in interest income using the effective interest method. After the purchase date, the allowance for credit losses is adjusted for subsequent changes in estimates of current expected credit losses. 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 three 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 future 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. Periods covered by 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 or additional ownership of 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 fair value, 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. Brokerage receivables are assessed for impairment applying the CECL model. 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 expected average remaining service period of the active participants expected to receive benefits from the plan. 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. Prior service costs are amortized on a straight-line basis over the expected average remaining service period of the active participants expected to receive benefits from the plan immediately after the date the plan amendment is adopted. 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. If the cost of settlements is above the threshold, the settlement gain or loss recognized in earnings is the actuarial net gain/loss transferred out of accumulated other comprehensive income. Where only a part of the PBO is settled, the amount recognized in earnings includes a proportionate share of the net actuarial gain/loss recognized in accumulated other comprehensive income equal to the percentage reduction of the PBO. The threshold is defined as the sum of the service cost and interest cost of that year. 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	Overview 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 credit 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.
Revisions of prior period financial statements, Policy [Text Block]	Certain accounting changes As noted in our 2021 Annual Report, the Bank identified an accounting issue that was not material to the prior period financial statements. The Bank identified this accounting issue with respect to the net balance sheet treatment relating to the presentation of a limited population of certain securities lending and borrowing activities. As a result, balance sheet and cash flow positions for both assets and liabilities relating to these activities were presented on a gross basis and prior periods were revised in the consolidated financial statements and the related notes. Beginning with the half-year ended June 30, 2022, the Bank has presented these securities lending and borrowing transactions as a single unit of account and as a result these transactions will no longer be presented on a gross basis. The Bank did not adjust prior period financial information, which continue to reflect a presentation on a gross basis.
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.

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 was 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.

Share-based Compensation Arrangement by Share-based Payment Award, Terms of Award			Deferred compensation awards are awarded to employees with total compensation of CHF/USD 250,000 or the local currency equivalent or higher. 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 material risk takers (MRTs), risk manager MRTs or senior managers or equivalents under the requirements of EU Capital Requirements Directive V and UK Investment Firms Prudential Regime. Share awards granted to MRTs vest over four years with one quarter of the award vesting on each of the four anniversaries of the grant date. Share awards granted to risk manager MRTs vest over five years with one fifth of the award vesting on each of the five anniversaries of the grant date. Share awards granted to senior managers vest over seven years, 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.

Share-based Compensation Arrangement by Share-based Payment Award [Line Items]
Share-based Compensation Arrangement by Share-based Payment Award, Terms of Award			Performance share awards will no longer be used as a form of deferred compensation award for the 2022 performance year and onwards. In prior years, 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, are subject to performance-based malus provisions.Outstanding performance share awards granted for prior years are subject to a downward adjustment in the event of a divisional loss by the division in which the employees worked as of December 31, 2022, or a negative ROE of the Group, whichever results in a larger adjustment. For employees in corporate functions and the Asset Resolution Unit, the downward 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. A downward adjustment has been applied to outstanding performance share awards, reflecting the negative Group ROE and full year divisional loss in the Investment Bank for 2022.

Share-based Compensation Arrangement by Share-based Payment Award, Terms of Award			Strategic Delivery PlanThe Strategic Delivery Plan (SDP) was a one-time share-based award granted in February 2022 to most managing directors and directors to incentivize the longer-term delivery of the Group’s strategic plan. SDP awards are subject to service conditions and performance-based metrics over the course of 2022-2024. SDP awards are scheduled to vest on the third anniversary of the grant date, with the exception of awards granted to individuals classified as MRTs, risk manager MRTs or senior managers or equivalents under the requirements of EU Capital Requirements Directive V and UK Investment Firms Prudential Regime. SDP awards granted to MRTs vest in equal annual installments over two years, commencing on the third anniversary from the grant date. SDP awards granted to risk manager MRTs vest in equal annual installments over three years, while SDP awards granted to senior managers vest in equal annual installments over five years, both commencing on the third anniversary from the grant date. Prior to settlement, the principal amount of the SDP awards will be written down to zero and forfeited if any of the following triggering events exist at the end of 2022, 2023 or 2024:■ The Group’s reported common equity tier 1 (CET1) capital ratio below the FINMA-prescribed minimum + 50 basis points; or■ The Group’s reported CET1 leverage ratio falls below 3.7%.In addition, the Compensation Committee will review and assess the overall success of the delivery of the strategic plan at a Group level over the three-year period (2022-2024) and may increase the SDP awards up to a maximum of 50% of the initial award amount. Half of the potential uplift would be granted if a pre-determined average Group return on tangible equity threshold is achieved, measured over 2023 and 2024. The other half of the uplift may be awarded based on the Compensation Committee’s assessment of risk management and other strategic non-financial achievements.

Deferred Compensation Arrangement with Individual, Excluding Share-based Payments and Postretirement Benefits [Line Items]
Deferred Compensation Arrangement with Individual, Description	Contingent Capital Awards (CCA) will no longer be used as a form of deferred compensation award for the 2022 performance year and onwards. The Group granted CCA of CHF 75 million and CHF 253 million in 2022 and 2021, respectively, to managing directors and directors as part of the 2021 and 2020 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 MRTs, risk manager MRTs or senior managers or equivalents under the requirements of EU Capital Requirements Directive V and UK Investment Firms Prudential Regime. CCA granted to MRTs, risk manager MRTs and senior managers vest on the fourth, fifth and seventh anniversaries of the grant date, respectively. CCA awards 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 2022 and 2021 that vest four, 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.■ CCA granted in 2022 and 2021 that are denominated in US dollars and vest three years from the date of grant receive interest equivalents at a rate of 4.18% and 3.60% respectively, per annum plus the daily compounded (spread exclusive) US dollar Secured Overnight Financing Rate (SOFR); and■ CCA granted in 2022 and 2021 that are denominated in Swiss francs and vest three years from the date of grant receive interest equivalents at a rate of 3.44% and 3.06% respectively, per annum plus the daily compounded (spread exclusive) Swiss franc Swiss Average Rate Overnight (SARON). 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. 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:■ the Group’s reported common equity tier 1 (CET1) ratio falls below 7%; or■ 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 or distributable reserves. For holding companies, legal reserves may be distributed if they exceed, after deduction of any accumulated losses, treasury shares and reserves for own shares held by subsidiaries, 20% of the share capital registered in the commercial register. Furthermore, dividends may be paid out only after shareholder approval.

Litigation disclosures
Litigation Settlement Terms	On February 28, 2023, FINMA announced the conclusion of its enforcement proceedings against Credit Suisse in connection with the SCFF matter. In its order, FINMA reported that Credit Suisse had seriously breached applicable Swiss supervisory laws in this context with regard to risk management and appropriate operational structures. While FINMA recognized that Credit Suisse has already taken extensive organizational measures based on its own investigation into the SCFF matter, particularly to strengthen its governance and control processes, and FINMA is supportive of these measures, the regulator has ordered certain additional remedial measures. These include a requirement that the most important (approximately 500) business relationships must be reviewed periodically and holistically at the Executive Board level, in particular for counterparty risks, and that Credit Suisse must set up a document defining the responsibilities of approximately 600 of its highest-ranking managers. FINMA will appoint an audit officer to assess compliance with these supervisory measures. Separate from the enforcement proceeding regarding Credit Suisse, FINMA has opened four enforcement proceedings against former managers of Credit Suisse.
