Recently issued accounting standards	2 Recently issued accounting standards Recently adopted accounting standards The following provides the most relevant recently adopted accounting standards. > Refer to “Note 2 – Recently issued accounting standards” in VI – Consolidated financial statements – Credit Suisse Group in the Credit Suisse Annual Report 2019 for a description of accounting standards adopted in 2019. ASC Topic 820 – Fair Value Measurement In August 2018, the Financial Accounting Standards Board (FASB) issued ASU 2018-13, “Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement” (ASU 2018-13), an update to Accounting Standards Codification (ASC) Topic 820 – Fair Value Measurement. The amendments in ASU 2018-13 removed, modified and added certain disclosure requirements in ASC Topic 820, Fair Value Measurement. ASU 2018-13 is effective for annual reporting periods beginning after December 15, 2019 and for the interim periods within those annual reporting periods. Early adoption was permitted, including in an interim period, for any eliminated or modified disclosure requirements. The Group early adopted the amendments for removing disclosures and the amendments for certain modifying disclosures upon the issuance of ASU 2018-13. The Group adopted the remaining amendments on January 1, 2020. As these amendments related only to disclosures, there was no impact from the adoption of ASU 2018-13 on the Group’s financial position, results of operations or cash flows. ASC Topic 326 – Financial Instruments – Credit Losses In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments” (ASU 2016-13), creating ASC Topic 326 – Financial Instruments – Credit Losses. ASU 2016-13 is intended to improve financial reporting by requiring timelier recording of credit losses on financial assets measured at amortized cost basis including, but not limited to loans, net investments in leases and off-balance sheet credit exposures. ASU 2016-13 eliminated the probable initial recognition threshold under the previous incurred loss methodology for recognizing credit losses. Instead, ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date over the remaining contractual life (considering the effect of prepayments) based on historical experience, current conditions and reasonable and supportable forecasts. The Group has incorporated forward-looking information and macroeconomic factors into its credit loss estimates. ASU 2016-13 requires enhanced disclosures to help investors and other financial statement users to better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. In May 2019, the FASB issued ASU 2019-05, “Financial Instruments – Credit Losses” (ASU 2019-05), to provide targeted transition relief upon the adoption of ASU 2016-13. The amendment provided the option to irrevocably elect the fair value option on certain financial assets on transition. As the Group is an SEC filer, ASU 2016-13 and its subsequent amendments were effective for annual reporting periods beginning after December 15, 2019, including interim periods within those annual reporting periods. The Group adopted ASU 2016-13 and its subsequent amendments on January 1, 2020, applying the modified retrospective approach, which resulted in a decrease in retained earnings of CHF 132 million, net of tax, with no significant impact on regulatory capital. Standards to be adopted in future periods ASC Topic 740 – Income Taxes In December 2019, the FASB issued ASU 2019-12, “Simplifying the Accounting for Income Taxes” (ASU 2019-12), an update to ASC Topic 740 – Income Taxes. The amendments in ASU 2019-12 eliminate certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the accounting for basis differences when there are changes in foreign ownership. In addition, ASU 2019-12 includes clarification and simplification of other aspects of the accounting for income taxes. The amendments are effective for annual reporting periods beginning after December 15, 2020 and for the interim periods within those annual reporting periods. Early adoption is permitted, including in an interim period. The Group is currently evaluating the impact of the adoption of ASU 2019-12 on the Group’s financial position, results of operations and cash flows. ASC Topic 848 – Reference Rate Reform In March 2020, the FASB issued ASU 2020-04, “Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (ASU 2020-04), creating ASC Topic 848 - Reference Rate Reform. The amendments in ASU 2020-04 provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments are elective and apply to contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate (LIBOR) or another reference rate expected to be discontinued because of reference rate reform. The Group may elect to apply the amendments as of March 12, 2020 through December 31, 2022. The Group is currently evaluating the impact of the adoption of ASU 2020-04 on the Group’s financial position, results of operations and cash flows.

Financial instruments measured at amortized cost and credit losses	18 Financial instruments measured at amortized cost and credit losses This disclosure provides an overview of the Group’s balance sheet positions that include financial assets carried at amortized cost that are subject to the CECL accounting guidance, effective since January 1, 2020. It includes the following sections: ■ ■ ■ ■ ■ ■ ■ As of the end of 2Q20, the Group had no notable balances of purchased financial assets with credit deterioration since origination.

Of the accrued interest balance, CHF 2 million relates to interest-bearing deposits with banks, CHF 453 million to loans and CHF 35 million to brokerage receivables. These accrued interest balances are reported in other assets. 3 Includes endangered interest of CHF 92 million on non-accrual loans which are reported as part of the loans' amortized cost balance. Allowance for credit losses Accounting policies The credit loss requirements apply to financial assets measured at amortized cost including for example loans held-to-maturity and net investments in leases as a lessor 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 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 (MEFs) 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 which 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 MEFs, such as gross domestic product (GDP), 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 (PD)/loss given default (LGD) approach under which PD, 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. 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. 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 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 leads to a change in the estimate of the associated PD. Lifetime PDs are estimated considering the expected macroeconomic environment, the contractual maturities of exposures and estimated prepayment rates where applicable. LGD estimates the size of the expected loss that may arise on a credit exposure in the event of a default. The Group estimates LGD based on the history of recovery rates of claims against defaulted counterparties, considering, as appropriate, factors such as differences in product structure, collateral type, seniority of the claim, counterparty industry and recovery costs of any collateral that is integral to the financial asset. Certain LGD values are also calibrated to reflect the expected macroeconomic environment. EAD represents the expected amount of credit exposure in the event of a default. It reflects the current drawn exposure with a counterparty and an expectation regarding the future evolution of the credit exposure under the contract or facility, including amortization and prepayments. The EAD of a financial asset is the gross carrying amount at default, which is modeled based on historical data considering portfolio-specific factors such as the drawn amount as of the reporting date, the facility limit, amortization schedules, financial collateral and product type. EAD models have a term structure and EADs are estimated based on historical observations. 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. For periods beyond the reasonable and supportable forecast period, the Group reverts immediately to average economic environment variables as model input factors. Alternative qualitative estimation approaches are used for certain products. For lombard loans (including share-backed loans), the PD/LGD approach used does not consider the Group’s forward looking forecasts as these are not meaningful for the estimate of expected credit losses in light of the short time-frame considered for closing out positions under daily margining arrangements. For international private residential mortgages and securitizations, the Group applies qualitative approaches where credit specialists follow a structured process and use their expertise and judgment to determine the CECL amounts. The Group measures expected credit losses considering the risk of default over the maximum contractual period (including any borrower’s extension options) during which it is exposed to credit risk, even if the Group considers a longer period for risk management purposes. The maximum contractual period extends to the date at which the Group has the right to require repayment of an advance or terminate an irrevocable loan commitment or a credit guarantee. Expected credit losses on impaired credit exposures Expected credit losses for individually impaired credit exposures are measured by performing an in-depth review and analysis of impaired credit exposures, considering factors such as recovery and exit options as well as collateral and the risk profile of the borrower. If an individual credit exposure specifically identified for evaluation is considered impaired, the allowance is determined as a reasonable estimate of expected credit losses as of the end of the reporting period. Thereafter, the allowance is revalued by Credit Risk Management, at least annually or more frequently, depending on the risk profile of the borrower or credit relevant events. For impaired loans and certain other financial assets, the expected credit loss is measured using the present value of estimated future cash flows and the impaired credit exposure 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 their contractual obligations, despite the current repayment status of their particular credit facility. 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. Current-period estimate of expected credit losses The estimation and application of forward-looking information requires quantitative analysis and significant judgement. The Group’s estimation of expected credit losses is based on a discounted probability-weighted estimate that considers three future macroeconomic scenarios to capture the point of non-linearity of losses: a baseline scenario, an upside scenario and a downside scenario. The baseline scenario represents the most likely outcome in line with the Group’s global chief investment office view. The two other scenarios represent more optimistic and more pessimistic outcomes with the downside scenario being more severe than the upside scenario. Under a more usual economic environment with projected continued economic expansion, 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 MEFs, such as GDP, unemployment rates and property prices. For extreme and statistically rare events which cannot be adequately reflected in CECL models, such as the current effects of the COVID-19 pandemic on the global economy, the extreme event becomes the baseline scenario and overlays based on expert judgment are applied in response to such exceptional circumstances. The scenario design team within the Group’s Enterprise Strategic Risk (ESR) function determines the MEFs and market projections that are relevant for the Group’s three scenarios across the global credit portfolio. The scenario design team formulates the baseline scenario projections used for the CECL calculation from the Group’s global chief investment office in-house economic research forecasts and, where deemed appropriate, from external sources such as the Bloomberg consensus of economist forecasts, forecasts from major central banks, nonpartisan think tanks 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 projections. The downside and upside scenarios are derived from these baseline projections. All three scenario projections are subject to a review and challenge process. Any feedback from the review and challenge process is incorporated into the scenario projections by the ESR scenario design team. The CECL scenario design working group is the governance forum. It performs an additional review and challenge and subsequently approves 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 The key MEFs used in each of the economic scenarios for the calculation of the expected credit losses include, but are not limited to, regional GDP, unemployment rates, interest rates, housing prices and commodity prices. These MEFs have been selected based on the portfolios that are most material to the estimation of CECL or in terms of CECL contribution from a longer term perspective. The following changes to the MEF calibrations were driven by the impact of the COVID-19 crisis on the global economy and led to increased CECL provisions. 1Q20 GDP data from the US, the eurozone and Switzerland confirmed the severe impact of COVID-19 induced lockdowns on economic activity. As a result, the Group’s global chief investment office economic research department also revised its projections for GDP in the US, the eurozone and Switzerland to reflect a collapse in economic activity in 2Q20, which was unprecedented since the Great Depression in the 1930s. The Group’s projections for the US unemployment rate in 2Q20 increased significantly compared to 1Q20, while the projections for developed economies and world industrial production decreased sharply. In addition, low oil prices in April and May led to significantly higher levels of oil market volatility for 2Q20 and the rest of 2020. 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 as credit loss expense or reversal of credit loss expense. 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 quarterly basis.

Assessment 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: ■ ■ ■ ■ The Group evaluates and assesses counterparties and clients to whom it has credit exposures, primarily using internal rating models. The Group 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 Management 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 rigorous 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 Management maintains regularly updated watch lists and holds review meetings to re-assess counterparties that could be subject to adverse changes in creditworthiness.

For mortgages, the value of collateral is determined at the time of granting the loan and thereafter regularly reviewed according to the Group's risk management policies and directives, with maximum review periods determined by property type, market liquidity and market transparency. Value of collateral In the Group’s private banking, corporate and institutional businesses, all collateral values for loans are regularly reviewed according to the Group’s risk management policies and directives, with maximum review periods determined by collateral type, market liquidity and market transparency. For example, traded securities are revalued on a daily basis and property values are appraised over a period of more than one year considering the characteristics of the property, current developments in the relevant real estate market and the current level of credit exposure to the borrower. If the credit exposure to a borrower has changed significantly, in volatile markets or in times of increasing general market risk, collateral values may be appraised more frequently. Management judgment is applied in assessing whether markets are volatile or general market risk has increased to a degree that warrants a more frequent update of collateral values. Movements in monitored risk metrics that are statistically different compared to historical experience are considered in addition to analysis of externally-provided forecasts, scenario techniques and macro-economic research. For impaired loans, the fair value of collateral is determined within 90 days of the date the impairment was identified and thereafter regularly revalued by Group credit risk management within the impairment review process. In the Group’s investment banking businesses, collateral-dependent loans are appraised on at least an annual basis, or wh

In accordance with US GAAP, the Group continually assesses whether or not there has been a triggering event requiring a review of goodwill. On July 30, 2020, the Group announced an updated strategy and related organizational changes, which included the introduction of a new segment structure with an effective date of August 1, 2020. Under the prior structure, the reporting units were Swiss Universal Bank – Private Clients, Swiss Universal Bank – Corporate & Institutional Banking, International Wealth Management – Private Banking, International Wealth Management – Asset Management, Asia Pacific – Wealth Management & Connected, Asia Pacific – Markets, Global Markets and Investment Banking & Capital Markets. As a result of the organizational changes, the Asia Pacific – Markets, Global Markets and Investment Banking & Capital Markets reporting units will be combined into one new reporting unit named Investment Bank. The anticipated announcement of the strategy and organizational changes represented a triggering event for goodwill impairment testing purposes and under US GAAP goodwill has to be tested for impairment before and immediately after a reorganization of reporting units. The goodwill impairment test performed was to evaluate whether or not a subsequent event for 2Q20 disclosure purposes had occurred rather than a test to determine if an impairment was required for June 2020. Based on this goodwill impairment analysis, the Group concluded that there would be no impairment necessary for its Global Markets, Investment Banking & Capital Markets and Asia Pacific - Markets reporting units under the current reporting structure as the estimated fair value of these reporting units exceeded their related carrying values by 11% 13% 6% The Group additionally considered the potential of impairment of the new reporting unit named Investment Bank. The estimated fair value of the reporting unit, based on pro-forma financial plans, substantially exceeds its related carrying value. The five-year strategic business plan used to derive the fair value included management’s assumptions as to when normalized market conditions would return as well as subsequent continued revenue growth. The approach for determining the carrying value and estimating the fair values of the reporting units was applied consistently for both the current reporting structure and the new reporting structure. The carrying value of each reporting unit for the purpose of the goodwill impairment test is determined by considering the reporting units’ risk-weighted assets usage, leverage ratio exposure, deferred tax assets, goodwill and intangible assets. Any residual equity, after considering the total of these elements, is allocated to the reporting units on a pro-rata basis. In estimating the fair value of its reporting units, the Group applied a combination of the market approach and income approach. Under the market approach, consideration was given to price to projected earnings multiples or price to book value multiples for similarly traded companies and prices paid in recent transactions that have occurred in its industry or in related industries. Under the income approach, a discount rate was applied that reflects the risk and uncertainty related to the reporting unit’s projected cash flows, which were determined from the Group’s financial plan. In determining the estimated fair value, the Group relied upon its latest five-year strategic business plan which included significant management assumptions and estimates based on its view of current and future economic conditions and regulatory changes. The Group engaged the services of an independent valuation specialist to assist in the valuation of the Asia Pacific – Markets, Global Markets and Investment Banking & Capital Markets reporting units under the current structure and the Investment Bank reporting unit under the new reporting structure as of June 30, 2020. The valuations were performed using a combination of the market approach and income approach. The results of the impairment evaluation of each reporting unit’s goodwill under the new reporting structure, in particular for the Investment Bank reporting unit, 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.

Offsetting of financial assets and financial liabilities	23 Offsetting of financial assets and financial liabilities The disclosures set out in the tables below include derivatives, reverse repurchase and repurchase agreements, and securities lending and borrowing transactions that: ■ ■ Similar agreements include derivative clearing agreements, global master repurchase agreements and global master securities lending agreements. Derivatives The Group transacts bilateral over-the-counter (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 26 – 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 global 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. Global 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 global master repurchase agreement on the same date shall be set off. Transactions under such agreements are netted in the consolidated balance sheets if they are with the same counterparty, have the same maturity date, settle through the same clearing institution 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 global master securities lending agreements with netting terms similar to ISDA Master Agreements. In certain situations, for example in the event of default, all contracts under the agreement are terminated and are settled net in one single payment. Transactions under these agreements are netted in the consolidated balance sheets if they meet the same right of offset criteria as for reverse repurchase and repurchase agreements. In general, most securities lending and borrowing transactions do not meet the criterion of having the same settlement date specified at inception of the transaction, and therefore they are not eligible for netting in the consolidated balance sheets. However, securities lending and borrowing transactions with explicit maturity dates may be eligible for netting in the consolidated balance sheets. Reverse repurchase and repurchase agreements are collateralized principally by government securities, money market instruments and corporate bonds and have terms ranging from overnight to a longer or unspecified period of time. In the event of counterparty default, the reverse repurchase agreement or securities lending agreement provides the Group with the right to liquidate the collateral held. As is the case in the Group’s normal course of business, a significant portion of the collateral received that may be sold or repledged was sold or repledged as of the end of 2Q20 and 4Q19. In certain circumstances, financial collateral received may be restricted during the term of the agreement (e.g., in tri-party arrangements). The following table presents the gross amount of securities purchased under resale agreements and securities borrowing transactions subject to enforceable master netting agreements, the amount of offsetting, the amount of securities purchased under resale agreements and securities borrowing transactions not subject to enforceable master netting agreements and the net amount presented in the consolidated balance sheets.

Tax	24 Tax The 2Q20 income tax charge of CHF 391 million includes the impact of the continuous reassessment of the estimated annual effective tax rate as well as the impact of items that need to be recorded in the specific interim period in which they occur. Further details are outlined in the tax expense reconciliation below. Net deferred tax assets related to NOLs, net deferred tax assets on temporary differences and net deferred tax liabilities are presented in the following manner. Nettable gross deferred tax liabilities are allocated on a pro-rata basis to gross deferred tax assets on NOLs and gross deferred tax assets on temporary differences. This approach is aligned with the underlying treatment of netting gross deferred tax assets and liabilities under the Basel III framework. Valuation allowances have been allocated against such deferred tax assets on net operating losses first with any remainder allocated to such deferred tax assets on temporary differences. This presentation is considered the most appropriate disclosure given the underlying nature of the gross deferred tax balances. As of June 30, 2020, the Group had accumulated undistributed earnings from foreign subsidiaries of CHF 16.5 billion which are considered indefinitely reinvested. The Group would need to accrue and pay taxes on these undistributed earnings if such earnings were repatriated. No deferred tax liability was recorded in respect of those amounts, as these earnings are considered indefinitely reinvested. It is not practicable to estimate the amount of unrecognized deferred tax liabilities for these undistributed foreign earnings. The Group is currently subject to ongoing tax audits, inquiries and litigation with the tax authorities in a number of jurisdictions, including Brazil, the Netherlands, Germany, the US, the UK and Switzerland. Although the timing of completion is uncertain, it is reasonably possible that some of these will be resolved within 12 months of the reporting date. It is reasonably possible that there will be a decrease between zero and CHF 39 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: Brazil – 2014; the UK – 2012; Switzerland – 2013; the US – 2010; and the Netherlands – 2010.

Other non-deductible expenses 2Q20 included the impact of CHF 45 million relating to non-deductible interest expenses and non-deductible bank levy costs. Changes in deferred tax valuation allowance 2Q20 included the impact of the estimated current year earnings, resulting in a decrease in valuation allowances of CHF 22 million, mainly in respect of three of the Group’s operating entities in the UK. Lower taxed income 2Q20 primarily included a tax benefit of CHF 14 million related to the Pfandbriefbank equity investment revaluation gain in Switzerland, an impact of CHF 13 million of non-taxable dividend income and an impact of CHF 12 million related to non-taxable life insurance income. The remaining balance included various smaller items. Other 2Q20 included an income tax expense of CHF 31 million, which mainly reflected the tax impact of CHF 24 million relating to withholding taxes, CHF 21 million from non-deductible fines and penalties and CHF 18 million relating to transitional adjustments arising on the first adoption of IFRS 9 for own credit movements. This was partially offset by a tax benefit of CHF 25 million relating to the beneficial earnings mix of one of the Group’s operating entities in Switzerland and prior years adjustments of CHF 5 million.

Other non-deductible expenses 6M20 primarily included CHF 33 million relating to non-deductible expenses, a net benefit of CHF 11 million due to non-deductible interest expenses (including the impact of previously unrecognized tax benefits of CHF 157 million relating to the resolution of interest cost deductibility with and between international tax authorities) and non-deductible bank levy costs. The remaining balance included various smaller items. Changes in deferred tax valuation allowance 6M20 included the impact of the estimated current year earnings, resulting in a decrease of valuation allowances of CHF 17 million mainly in respect of one of the Bank’s operating entities in the UK and Japan and an increase of valuation allowances of CHF 5 million mainly in respect of one of the Bank’s operating entities in Germany. Lower taxed income 6M20 primarily included the impacts of CHF 31 million related to non-taxable life insurance income, CHF 26 million related to the Pfandbriefbank equity investment revaluation gain in Switzerland and the completed transfer of the InvestLab fund platform to Allfunds Group, CHF 22 million related to non-taxable dividend income and non-taxable offshore results of CHF 5 million. Other 6M20 included a tax benefit of CHF 273 million, which mainly reflected the impact of the re-assessment of the US base erosion and anti-abuse tax (BEAT) provision for 2019 of CHF 180 million and the impact from a change in US tax rules relating to federal net operating losses (NOLs) where federal NOLs generated in tax years 2018, 2019 or 2020 can be carried back for five-years instead of no carry back before and also the deductible interest expense limitations for the years 2019 and 2020 have been increased from 30% to 50% of adjusted taxable income for the year, which in aggregate resulted in a benefit of CHF 141 million. It also included a tax benefit of CHF 68 million relating to the beneficial earnings mix of one of the Bank’s operating entities in Switzerland. This was partially offset by a tax charge of CHF 44 million relating to the tax impact of transitional adjustments arising on the first adoption of IFRS 9 for own credit movements, CHF 38 million relating to withholding taxes, CHF 21 million relating to uncertain tax positions, CHF 21 million relating to the impact of a prior year adjustment and CHF 9 million relating to the current year BEAT provision. The remaining balance included various smaller items. The US tax reform enacted in December 2017 introduced the BEAT tax regime, effective as of January 1, 2018, for which final regulations were issued by the US Department of Treasury on December 2, 2019. Following the publication of the 2019 financial results, Credit Suisse continued its analysis of the final regulations, resulting in a revision to the technical application of the prior BEAT estimate. This new information was not available or reasonably knowable at the time of the publication of the 2019 financial statements and resulted in a change of accounting estimate reflected in 6M20.

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

Credit derivatives > Refer to “Note 32 – Derivatives and hedging activities” in VI – Consolidated financial statements – Credit Suisse Group in the Credit Suisse Annual Report 2019 for further information on credit derivatives. 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” tables. 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 15.8 billion and CHF 16.7 billion as of the end of 2Q20 and 4Q19 were also excluded because a TRS does not expose the seller to potential loss from credit risk-related events specified in the contract.

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. 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. 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. 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.

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

Credit derivatives > Refer to “Note 31 – Derivatives and hedging activities” in VIII – Consolidated financial statements – Credit Suisse (Bank) in the Credit Suisse Annual Report 2019 for further information on credit derivatives. 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” tables. 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 15.8 billion and CHF 16.7 billion as of the end of 6M20 and 2019, respectively, were also excluded because a TRS does not expose the seller to potential loss from credit risk-related events specified in the contract. A TRS only provides protection against a loss in asset value and not against additional amounts as a result of specific credit events.

Guarantees and commitments

Guarantees and commitments	6 Months Ended

Guarantees and commitments	28 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. > Refer to “Guarantees” in VI – Consolidated financial statements – Credit Suisse Group – Note 33 – Guarantees and commitments in the Credit Suisse Annual Report 2019 for a detailed description of guarantees.

Deposit-taking banks and securities dealers in Switzerland and certain other European countries are required to ensure the payout of privileged deposits in case of specified restrictions or compulsory liquidation of a deposit-taking bank. In Switzerland, deposit-taking banks and securities dealers jointly guarantee an amount of up to CHF 6 billion. Upon occurrence of a payout event triggered by a specified restriction of business imposed by FINMA or by the compulsory liquidation of another deposit-taking bank, the Group’s contribution will be calculated based on its share of privileged deposits in proportion to total privileged deposits. Based on FINMA’s estimate for the Group’s banking subsidiaries in Switzerland, the Group’s share in the deposit insurance guarantee program for the period July 1, 2019 to June 30, 2020 was CHF 0.5 billion. These deposit insurance guarantees were reflected in other guarantees. For the period July 1, 2020 to June 30, 2021, the Group’s share in the deposit insurance guarantee program based on FINMA’s estimate will be CHF 0.5 billion. Representations and warranties on residential mortgage loans sold In connection with the Global Markets 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; LTV 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 32 – 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 include disposal-related contingencies in connection with the sale of assets or businesses, and other indemnifications. These guarantees are not reflected in the “Guarantees” table. > Refer to “Disposal-related contingencies and other indemnifications” in VI – Consolidated financial statements – Credit Suisse Group – Note 33 – Guarantees and commitments in the Credit Suisse Annual Report 2019 for a description of these guarantees. Other commitments Other commitments of the Group are classified as follows: irrevocable commitments under documentary credits, irrevocable loan commitments, forward reverse repurchase agreements and other commitments. > Refer to “Other commitments” in VI – Consolidated financial statements – Credit Suisse Group – Note 33 – Guarantees and commitments in the Credit Suisse Annual Report 2019 for a description of these commitments.

Deposit-taking banks and securities dealers in Switzerland and certain other European countries are required to ensure the payout of privileged deposits in case of specified restrictions or compulsory liquidation of a deposit-taking bank. In Switzerland, deposit-taking banks and securities dealers jointly guarantee an amount of up to CHF 6 billion. Upon occurrence of a payout event triggered by a specified restriction of business imposed by 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’s banking subsidiaries in Switzerland, the Bank’s share in the deposit insurance guarantee program for the period July 1, 2019 to June 30, 2020 was CHF 0.5 billion. These deposit insurance guarantees were reflected in other guarantees. For the period July 1, 2020 to June 30, 2021, the Bank’s share in this deposit insurance guarantee program based on FINMA’s estimate will be CHF 0.5 billion.

Transfers of financial assets and variable interest entities	29 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, commercial papers (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), RMBS and asset-backed securities (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. Typically, certificates issued out of an existing securitization vehicle are sold into a newly created and separate securitization vehicle. Often, these re-securitizations are initiated in order to re-securitize an existing security to give the investor an investment with different risk ratings or characteristics. The Group also uses SPEs for other asset-backed financings relating to client-driven activity and for Group tax or regulatory purposes. Types of structures included in this category include managed collateralized loan obligations (CLOs), CLOs, leveraged finance, repack and other types of transactions, including life insurance structures, emerging market structures set up for financing, loan participation or loan origination purposes, and other alternative structures created for the purpose of investing in venture capital-like investments. CLOs are collateralized by loans transferred to the CLO vehicle and pay a return based on the returns on the loans. Leveraged finance structures are used to assist in the syndication of certain loans held by the Group, while repack structures are designed to give a client collateralized exposure to specific cash flows or credit risk backed by collateral purchased from the Group. In these asset-backed financing structures, investors typically only have recourse to the collateral of the SPE and do not have recourse to the Group’s assets. When the Group transfers assets into an SPE, it must assess whether that transfer is accounted for as a sale of the assets. Transfers of assets may not meet sale requirements if the assets have not been legally isolated from the Group and/or if the Group’s continuing involvement is deemed to give it effective control over the assets. If the transfer is not deemed a sale, it is instead accounted for as a secured borrowing, with the transferred assets as collateral. Gains and losses on securitization transactions depend, in part, on the carrying values of mortgages and loans involved in the transfer and are allocated between the assets sold and any beneficial interests retained according to the relative fair values at the date of sale. The Group does not retain material servicing responsibilities from securitization activities. The following table provides the gains or losses and proceeds from the transfer of assets relating to 6M20 and 6M19 securitizations of financial assets that qualify for sale accounting and subsequent derecognition, along with the cash flows between the Group and the SPEs used in any securitizations in which the Group still has continuing involvement, regardless of when the securitization occurred.

The gains or losses on the sale of the collateral is the difference between the fair value on the day prior to the securitization pricing date and the sale price of the loans. 2 Represents management fees and performance fees earned for investment management services provided to managed CLOs. Continuing involvement in transferred financial assets The Group may have continuing involvement in the financial assets that are transferred to an SPE which may take several forms, including, but not limited to, servicing, recourse and guarantee arrangements, agreements to purchase or redeem transferred assets, derivative instruments, pledges of collateral and beneficial interests in the transferred assets. > Refer to “Transfer of financial assets” in VI – Consolidated financial statements – Credit Suisse Group – Note 34 – Transfer of financial assets and variable interest entities in the Credit Suisse Annual Report 2019 for a detailed description of continuing involvement in transferred financial assets. The following table provides the outstanding principal balance of assets to which the Group continued to be exposed after the transfer of the financial assets to any SPE and the total assets of the SPE as of the end of 2Q20 and 4Q19, regardless of when the transfer of assets occurred. Principal amounts outstanding and total assets of SPEs resulting from continuing involvement end of 2Q20 4Q19 CHF million CMBS Principal amount outstanding 20,184 21,079 Total assets of SPE 26,731 28,748 RMBS Principal amount outstanding 55,801 54,001 Total assets of SPE 57,228 55,595 Other asset-backed financings Principal amount outstanding 25,905 27,982 Total assets of SPE 50,594 54,974 Principal amount outstanding relates to assets transferred from the Group and does not include principal amounts for assets transferred from third parties. Fair value of beneficial interests The fair value measurement of the beneficial interests held at the time of transfer and as of the reporting date that result from any continuing involvement is determined using fair value estimation techniques, such as the present value of estimated future cash flows that incorporate assumptions that market participants customarily use in these valuation techniques. The fair value of the assets or liabilities that result from any continuing involvement does not include any benefits from financial instruments that the Group may utilize to hedge the inherent risks. Key economic assumptions at the time of transfer > Refer to “Note 30 – Financial instruments” for further information on the fair value hierarchy.

PSA utilizes the constant prepayment rate (CPR) assumptions. A 100% prepayment assumption assumes a prepayment rate of 0.2% per annum of the outstanding principal balance of mortgage loans in the first month. This increases by 0.2 percentage points thereafter during the term of the mortgage loan, leveling off to a CPR of 6% per annum beginning in the 30th month and each month thereafter during the term of the mortgage loan. 100 PSA equals 6 CPR. 2 To deter prepayment, commercial mortgage loans typically have prepayment protection in the form of prepayment lockouts and yield maintenances. 3 The rate is based on the weighted-average yield on the beneficial interests. 4 The range of expected credit losses only reflects instruments with an expected credit loss greater than zero unless all of the instruments have an expected credit loss of zero. Key economic assumptions as of the reporting date The following table provides the sensitivity analysis of key economic assumptions used in measuring the fair value of beneficial interests held in SPEs as of the end of 2Q20 and 4Q19.

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 the end of 2Q20 and 4Q19. > Refer to “Note 31 – 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 the end of 2Q20 and 4Q19.

Variable interest entities As a normal part of its business, the Group engages in various transactions that include entities that are considered variable interest entities (VIEs) and are grouped into three primary categories: collateralized debt obligations (CDOs)/CLOs, CP conduits and financial intermediation. > Refer to “Variable interest entities” in VI – Consolidated financial statements – Credit Suisse Group – Note 34 – Transfer of financial assets and variable interest entities in the Credit Suisse Annual Report 2019 for a detailed description of VIEs, CDO/CLOs, CP conduit or financial intermediation. 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, in the case of CLOs, loans. The Group may act as underwriter, placement agent or asset manager and may warehouse assets prior to the closing of a transaction. 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 161 days as of the end of 2Q20. Alpine’s CP was rated A-1(sf) by Standard & Poor’s and P-1(sf) by Moody’s and had exposures mainly in reverse repurchase agreements with a Group entity, consumer loans, solar loans and leases, aircraft loans and leases and car loans and leases. The Group’s financial commitment to this CP conduit consists of obligations under liquidity agreements. The liquidity agreements are asset-specific arrangements, which require the Group to provide short-term financing to the CP conduit or to purchase assets from the CP conduit in certain circumstances, including but not limited to, a lack of liquidity in the CP market such that the CP conduit cannot refinance its obligations or a default of an underlying asset. The asset-specific credit enhancements provided by the client seller of the assets remain unchanged as a result of such a purchase. In entering into such agreements, the Group reviews the credit risk associated with these transactions on the same basis that would apply to other extensions of credit. The Group enters into liquidity facilities with CP conduits administrated and sponsored by third parties. These third-party CP conduits are considered to be VIEs for accounting purposes. The Group is not the primary beneficiary and does not consolidate these third-party CP conduits. The Group’s financial commitment to these third-party CP conduits consists of obligations under liquidity agreements. The liquidity agreements are asset-specific arrangements, which require the Group to provide short-term financing to the third-party CP conduits or to purchase assets from these CP conduits in certain circumstances, including but not limited to, a lack of liquidity in the CP market such that the CP conduits cannot refinance their obligations or a default of an underlying asset. The asset-specific credit enhancements, if any, provided by the client seller of the assets remain unchanged as a result of such a purchase. In entering into such agreements, the Group reviews the credit risk associated with these transactions on the same basis that would apply to other extensions of credit. In some situations, the Group can enter into liquidity facilities with these third-party CP conduits through Alpine. As of the end of 2Q20 and 4Q19, the Group’s outstanding facilities provided to these third-party conduits through Alpine are not included in the tabular disclosure of non-consolidated VIEs and represent a maximum exposure to loss of CHF 6,157 million and CHF 6,159 million, respectively, and total assets of these non-consolidated VIEs of CHF 13,103 million and CHF 13,488 million, respectively. 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. Financial intermediation consists of securitizations, funds, loans and other vehicles. Consolidated VIEs The Group has significant involvement with VIEs in its role as a financial intermediary on behalf of clients. The Group consolidates all VIEs related to financial intermediation for which it was the primary beneficiary. The consolidated VIEs table provides the carrying amounts and classifications of the assets and liabilities of consolidated VIEs as of the end of 2Q20 and 4Q19.

The gains or losses on the sale of the collateral is the difference between the fair value on the day prior to the securitization pricing date and the sale price of the loans. 2 Represents management fees and performance fees earned for investment management services provided to managed CLOs. Continuing involvement in transferred financial assets The following table provides the outstanding principal balance of assets to which the Bank continued to be exposed after the transfer of the financial assets to any SPE and the total assets of the SPE as of the end of 6M20 and 2019, regardless of when the transfer of assets occurred.

Fair value of beneficial interests The fair value measurement of the beneficial interests held at the time of transfer and as of the reporting date that result from any continuing involvement is determined using fair value estimation techniques, such as the present value of estimated future cash flows that incorporate assumptions that market participants customarily use in these valuation techniques. The fair value of the assets or liabilities that result from any continuing involvement does not include any benefits from financial instruments that the Bank may utilize to hedge the inherent risks. Key economic assumptions at the time of transfer > Refer to “Note 29 – Financial instruments” for information on fair value hierarchy levels.

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.

Variable interest entities 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 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 161 days as of the end of 6M20. Alpine’s CP was rated A-1(sf) by Standard & Poor’s and P-1(sf) by Moody’s. Alpine had exposures mainly in reverse repurchase agreements with a Group entity, consumer loans, solar loans and leases, aircraft loans and leases and car loans and leases. The Bank’s financial commitment to this CP conduit consists of obligations under liquidity agreements. The liquidity agreements are asset-specific arrangements, which require the Bank to provide short-term financing to the CP conduit or to purchase assets from the CP conduit in certain circumstances, including but not limited to, a lack of liquidity in the CP market such that the CP conduit cannot refinance its obligations or a default of an underlying asset. 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 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. 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. As of the end of 6M20 and 2019, the Bank’s outstanding facilities provided to these third-party conduits through Alpine are not included in the tabular disclosure of non-consolidated VIEs and represent a maximum exposure to loss of CHF 6,157 million and CHF 6,159 million, respectively, and total assets of these non-consolidated VIEs of CHF 13,103 million and CHF 13,488 million, respectively. 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.

As of 6M19, changes in net unrealized gains/(losses) of CHF (925) 2 Prior period has been corrected. Both observable and unobservable inputs may be used to determine the fair value of positions that have been classified within level 3. As a result, the unrealized gains and losses for assets and liabilities within level 3 presented in the table above may include changes in fair value that were attributable to both observable and unobservable inputs. The Group employs various economic hedging techniques in order to manage risks, including risks in level 3 positions. Such techniques may include the purchase or sale of financial instruments that are classified in levels 1 and/or 2. The realized and unrealized gains and losses for assets and liabilities in level 3 presented in the table above do not reflect the related realized or unrealized gains and losses arising on economic hedging instruments classified in levels 1 and/or 2. The Group typically uses nonfinancial assets measured at fair value on a recurring or nonrecurring basis in a manner that reflects their highest and best use. Transfers in and out of level 3 Transfers into level 3 assets during 6M20 were CHF 4,564 million, primarily from trading assets, loans held-for-sale and loans. These transfers were primarily in the securitized products, credit and financing businesses due to limited observability of pricing data. Transfers out of level 3 assets during 6M20 were CHF 2,260 million, primarily in trading assets, loans and loans held-for-sale. These transfers were primarily in the credit, financing and equity derivatives businesses due to increased observability of pricing data and increased availability of pricing information from external providers. Transfers into level 3 assets during 2Q20 were CHF 1,611 million, primarily from trading assets, loans held-for-sale and loans. These transfers were primarily in the securitized products, credit and equity derivatives businesses due to limited observability of pricing data. Transfers out of level 3 assets during 2Q20 were CHF 1,466 million, primarily in trading assets, loans and loans held-for-sale. These transfers were primarily in the credit, financing and equity derivatives businesses due to increased observability of pricing data and increased availability of pricing information from external providers. Transfers out of level 3 liabilities of CHF 6,730 million in 6M20 and CHF 5,698 million in 2Q20 primarily reflected transfers of structured notes over two years arising from an enhancement to the assessment of the valuation significance of unobservable input parameters on equity linked issuances. Uncertainty of fair value measurements at the reporting date from the use of significant unobservable inputs For level 3 assets with significant unobservable inputs of buyback probability, correlation, credit curve volatility, funding spread, mortality rate, price, recovery rate, volatility or volatility skew, in general, an increase in the significant unobservable input would increase the fair value. For level 3 assets with significant unobservable inputs of credit spread, default rate, discount rate, gap risk, market implied life expectancy (for life settlement and premium finance instruments) or prepayment rate, in general, an increase in the significant unobservable input would decrease the fair value. For level 3 liabilities, in general, an increase in the related significant unobservable inputs would have an inverse impact on fair value. An increase in the significant unobservable inputs correlation, contingent probability, credit curve volatility, credit spread, gap risk, market implied life expectancy, price, recovery rate or volatility would increase the fair value. An increase in the significant unobservable inputs buyback probability, correlation, discount rate, fund gap risk, funding spread, mean reversion, mortality rate or prepayment rate would decrease the fair value. Interrelationships between significant unobservable inputs Except as noted above, there are no material interrelationships between the significant unobservable inputs for the financial instruments. As the significant unobservable inputs move independently, generally an increase or decrease in one significant unobservable input will have no impact on the other significant unobservable inputs. Quantitative disclosures of valuation techniques The following tables provide the representative range of minimum and maximum values and the associated weighted averages of each significant unobservable input for level 3 assets and liabilities by the related valuation technique most significant to the related financial instrument.

Litigation

Litigation	6 Months Ended
	Jun. 30, 2020
Litigation	32 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. The Group’s material proceedings, related provisions and estimate of the aggregate range of reasonably possible losses that are not covered by existing provisions are described in Note 39 – Litigation in VI – Consolidated fi nancial statements – Credit Suisse Group in the Credit Suisse Annual Report 2019 The Group accrues loss contingency litigation provisions and takes a charge to income in connection with certain proceedings when losses, additional losses or ranges of loss are probable and reasonably estimable. The Group also accrues litigation provisions for the estimated fees and expenses of external lawyers and other service providers in relation to such proceedings, including in cases for which it has not accrued a loss contingency provision. The Group accrues these fee and expense litigation provisions and takes a charge to income in connection therewith when such fees and expenses are probable and reasonably estimable. The Group reviews its legal proceedings each quarter to determine the adequacy of its litigation provisions and may increase or release provisions based on management’s judgment and the advice of counsel. The establishment of additional provisions or releases of litigation provisions may be necessary in the future as developments in such proceedings warrant. The specific matters described 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 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 the Group has disclosed the amount of damages claimed and certain other quantifiable information that is publicly available. 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 in Note 39 referenced above and updated in quarterly reports (including below) for which the Group believes an estimate is possible is zero to CHF 1.3 billion. In 2Q20, the Group recorded net litigation provisions of CHF 120 million. 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 Civil litigation Individual investor actions On July 16, 2020, following a settlement, the Washington state court presiding in the investor action brought by the Federal Home Loan Bank of Seattle dismissed with prejudice all claims against Credit Suisse Securities (USA) LLC (CSS LLC) and its affiliates relating to approximately USD 145 million of RMBS at issue.

SSA bonds litigation On June 1, 2020, in the consolidated class action litigation brought in the SDNY relating to supranational, sub-sovereign and agency (SSA) bonds, plaintiffs filed a notice of appeal. On June 25, 2020, in the putative class action brought in the SDNY on behalf of indirect purchasers of US dollar SSA bonds, plaintiff voluntarily dismissed the lawsuit. Government-sponsored entity bonds litigation On June 16, 2020, in the consolidated putative class action brought in the SDNY alleging a conspiracy among financial institutions to fix prices for unsecured bonds issued by certain government-sponsored entities, the court issued an order granting final approval to all settlements, including the global settlement to which CSS LLC is a party. On July 13, 2020, in the civil action filed on September 23, 2019 in the US District Court for the Middle District of Louisiana alleging a conspiracy among financial institutions to fix prices for unsecured bonds issued by certain government-sponsored entities, plaintiff filed an amended complaint. On July 24, 2020, Credit Suisse AG and CSS LLC filed an answer. On June 26, 2020, in the civil action in the US District Court for the Eastern District of Louisiana alleging a conspiracy among financial institutions to fix prices for unsecured bonds issued by certain government-sponsored entities, CSS LLC and certain other defendants filed a partial motion to dismiss state law claims brought under the Louisiana Unfair Trade Practices Act. On July 17, 2020, the plaintiff filed a first amended complaint in response to the partial motion to dismiss. OTC trading cases On July 14, 2020, in the putative class action filed in the SDNY alleging a conspiracy among CSS LLC and other financial institutions to boycott electronic trading platforms and fix prices in the secondary market for odd-lot corporate bonds, plaintiff filed an amended complaint. ATA litigation On May 28, 2020, in the action filed on November 9, 2017 in the SDNY alleging claims under the United States Anti-Terrorism Act (ATA), plaintiffs filed a motion to appeal the court’s February 25, 2020 decision dismissing the case with prejudice as to Credit Suisse AG and the other moving bank defendants, which the moving defendants opposed on June 11, 2020. On June 5, 2020, the US District Court for the Eastern District of New York (EDNY) granted defendants’ motion to dismiss two of the ATA cases that were filed in December 2018 and April 2019 in the EDNY as to Credit Suisse AG and most of the other bank defendants. Customer account matters On July 3, 2020, in the civil lawsuit brought against a Credit Suisse affiliate, the Singapore Court of Appeals granted the plaintiffs’ appeal and lifted the stay of the civil proceedings, allowing the plaintiffs’ civil claim against the Credit Suisse affiliate to proceed in the Singapore High Court. On July 10, 2020, plaintiffs filed an amended statement of claim in the Singapore High Court. Mozambique matter Credit Suisse is continuing to respond to requests from regulatory and enforcement authorities regarding certain Credit Suisse entities’ participation in transactions involving Mozambique state enterprises, and is in ongoing dialogue with certain of these authorities regarding the nature of Credit Suisse’s role. Write-downs litigation On July 8, 2020, in the putative class action brought in the SDNY relating to write-downs in the fourth quarter of 2015 and the first quarter of 2016 and a decline in the market value of Credit Suisse Group AG American Depositary Receipts, the parties entered into an agreement to settle all claims for USD 15.5 million. A motion for preliminary approval of the proposed settlement was filed on July 10, 2020, and the court has scheduled a preliminary approval hearing for August 6, 2020. The settlement remains subject to final approval by the court. ETN-related litigation On April 14, 2020, in the individual action filed on March 29, 2019 in the SDNY by a purchaser of VelocityShares Daily Inverse VIX Short Term Exchange Traded Notes linked to the S&P 500 VIX Short-Term Futures Index due December 4, 2030 (XIV ETNs), plaintiff filed a motion for voluntary dismissal with prejudice of its appeal, which was granted by the Second Circuit on April 15, 2020. In the class action in the SDNY brought on behalf of a putative class of purchasers of VelocityShares Daily Inverse VIX Medium Term Exchange Traded Notes linked to the S&P 500 VIX Mid-Term Futures Index due December 4, 2030 (ZIV ETNs), plaintiffs did not appeal the decision by the SDNY to dismiss all claims against the defendants and the judgment is now final.

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

This increases by 0.2 percentage points thereafter during the term of the mortgage loan, leveling off to a CPR of 6% per annum beginning in the 30th month and each month thereafter during the term of the mortgage loan. 100 PSA equals 6 CPR. 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.

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.
