Recently issued accounting stan

Recently issued accounting standards	6 Months Ended
	Jun. 30, 2019
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 2018 for a description of accounting standards adopted in 2018. ASC Topic 220 – Income Statements – Reporting Comprehensive Income In January 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” (ASU 2018-02), an update to Accounting Standards Codification (ASC) Topic 220 – Income Statement – Reporting Comprehensive Income. The amendments in ASU 2018-02 allowed a reclassification from accumulated other comprehensive income (AOCI) to retained earnings for the stranded tax effects resulting from the US Tax Cuts and Jobs Act. ASU 2018-02 was effective for annual reporting periods and interim periods within those periods beginning after December 15, 2018. Early adoption was permitted. The adoption of ASU 2018-02 on January 1, 2019 resulted in a net increase in retained earnings of CHF 64 million as a result of the reclassification from AOCI to retained earnings, which was the result of the re-measurement of deferred tax assets and liabilities associated with the change in tax rates. ASC Topic 350 – Intangibles – Goodwill and Other In August 2018, the FASB issued ASU 2018-15, “Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract” (ASU 2018-15), an update to ASC Subtopic 350-40 – Intangibles – Goodwill and Other – Internal-Use Software. The amendments in ASU 2018-15 align the requirements for capitalizing costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. ASU 2018-15 is effective for annual reporting periods beginning after December 15, 2019, including interim periods within those annual reporting periods and can be applied either retrospectively or prospectively. Early adoption, including adoption in an interim period, was permitted. The Group elected to early adopt ASU 2018-15 prospectively on January 1, 2019. The adoption of ASU 2018-15 did not have a material impact on the Group’s financial position, results of operations or cash flows. ASC Topic 815 – Derivatives and Hedging In August 2017, the FASB issued ASU 2017-12, “Targeted Improvements to Accounting for Hedging Activities” (ASU 2017-12), an update to ASC Topic 815 – Derivatives and Hedging. ASU 2017-12 made changes to the hedge accounting model intended to facilitate financial reporting that more closely reflected an entity’s risk management activities and simplified application of hedge accounting. The amendments in ASU 2017-12 provided more hedging strategies that will be eligible for hedge accounting, eased the documentation and effectiveness assessment requirements and resulted in changes to the presentation and disclosure requirements of hedge accounting activities. ASU 2017-12 was effective for annual reporting periods beginning after December 15, 2018, and for the interim periods within those annual reporting periods. Early adoption, including adoption in an interim period, was permitted. The adoption of ASU 2017-12 on January 1, 2019 did not have a material impact on the Group’s financial position, results of operations and cash flows. In October 2018, the FASB issued ASU 2018-16, “Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes” (ASU 2018-16), an update to ASC Topic 815 – Derivatives and Hedging. ASU 2018-16 permitted the use of the OIS rate based on the SOFR as a US benchmark interest rate for hedge accounting purposes and was effective for the Group on January 1, 2019. The adoption of ASU 2018-16 on January 1, 2019 did not impact the Group’s existing hedges. ASC Topic 820 – Fair Value Measurement In August 2018, the FASB issued ASU 2018-13, “Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement” (ASU 2018-13), an update to ASC Topic 820 – Fair Value Measurement. The amendments in ASU 2018-13 remove, modify and add 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 is permitted, including in an interim period, for any eliminated or modified disclosure requirements. The Group early adopted the provisions for removing and modifying certain disclosures upon issuance of ASU 2018-13. As these amendments relate to disclosures, the adoption did not have an impact on the Group’s financial position, results of operations or cash flows. The Group is currently evaluating the impact of the adoption of the remaining amendments in ASU 2018-13. ASC Topic 842 – Leases In February 2016, the FASB issued ASU 2016-02, “Leases” (ASU 2016-02), creating ASC Topic 842 – Leases and superseding ASC Topic 840 – Leases. ASU 2016-02 set out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. ASU 2016-02 also included disclosure requirements to provide more information about the amount, timing and uncertainty of cash flows arising from leases. Lessor accounting was substantially unchanged compared to the previous accounting guidance. Under the previous lessee accounting model the Group is required to distinguish between finance leases, which are recognized on the balance sheet, and operating leases, which are not. ASU 2016-02 required lessees to present a right-of-use asset and a corresponding lease liability on the balance sheet irrespective of the lease classification. The Group adopted ASU 2016-02 and its subsequent amendments on January 1, 2019 using the modified retrospective approach, with a transition adjustment recognized in retained earnings without restating comparatives. The Group elected the use of the package of practical expedients and the practical expedient to use hindsight. As a result of adoption, the Group recognized lease liabilities and related right-of-use assets of approximately CHF 3.5 billion and CHF 3.3 billion, respectively. In addition, the Group recognized an increase in retained earnings of approximately CHF 0.2 billion, net of tax, which included the release of previously deferred gains on sale lease-back transactions and previously unrecognized impairment losses. Standards to be adopted in future periods 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 recognized as lessor and off-balance sheet credit exposures. ASU 2016-13 eliminates the probable initial recognition threshold under the current 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 based on historical experience, current conditions and reasonable and supportable forecasts. The Group will incorporate 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. As the Group is a US Securities and Exchange Commission filer, ASU 2016-13 and its subsequent amendments are effective for annual reporting periods beginning after December 15, 2019, including interim periods within those annual reporting periods. Early adoption is permitted for annual reporting periods, including interim periods within those annual reporting periods, beginning after December 15, 2018. The Group plans to adopt ASU 2016-13 and its subsequent amendments on January 1, 2020. The Group has established a cross-functional implementation team and governance structure for the project. The Group has decided on a current expected credit loss (CECL) methodology and continues to adjust for key interpretive issues while monitoring the FASB’s ongoing accounting standards development. The Group intends to utilize multiple macroeconomic scenarios in estimating expected credit losses. Furthermore, the Group will continue to monitor the scope assessment to determine the requirements and data sourcing of the CECL models as well as continue to build and test the models until the effective date. The Group expects to complete model validation and control testing through the remainder of 2019. The Group expects that the new CECL methodology would generally result in increased and more volatile allowance for loan losses. The main impact drivers include: ■ ■ ■ Upon adoption of the standard, the Group expects a cumulative adjustment to retained earnings for any changes in credit loss allowances. As the implementation progresses, the Group will continue to evaluate the extent of the impact of the adoption of ASU 2016-13 and its subsequent amendments on the Group’s financial position, results of operations, cash flows and related disclosures. ASC Topic 715 – Compensation – Retirement Benefits In August 2018, the FASB issued ASU 2018-14, “Changes to the Disclosure Requirements for Defined Benefit Plans” (ASU 2018-14), an update to ASC Topic 715 – Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework. ASU 2018-14 modifies the disclosure framework to improve disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. ASU 2018-14 is effective for annual reporting periods ending after December 15, 2020, with early adoption permitted. ASU 2018-14 should be applied on a retrospective approach for all periods presented. As these amendments relate only to disclosures, there will be no impact from the adoption of ASU 2018-14 on the Group’s financial position, results of operations or cash flows.

The Group determined in 2Q19 that a goodwill triggering event occurred for the Asia Pacific – Markets, Global Markets and Investment Banking & Capital Markets reporting units. Based on its goodwill impairment analysis performed as of June 30, 2019, the Group concluded that the estimated fair value for all of the reporting units with goodwill substantially exceeded their related carrying values and no impairment was necessary as of June 30, 2019. 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 the income approach. Under the market approach, consideration was given to price to projected earnings multiples or price to book value multiples for similarly traded companies and prices paid in recent transactions that have occurred in its industry or in related industries. Under the income approach, a discount rate was applied that reflects the risk and uncertainty related to the reporting unit’s projected cash flows, which were determined from the Group’s financial plan. In determining the estimated fair value, the Group relied upon its latest five-year strategic business plan which included significant management assumptions and estimates based on its view of current and future economic conditions and regulatory changes, and as approved by the Board of Directors. The results of the impairment evaluation of each reporting unit’s goodwill would be significantly impacted by adverse changes in the underlying parameters used in the valuation process. If actual outcomes adversely differ by a significant margin from its best estimates of the key economic assumptions and associated cash flows applied in the valuation of the reporting unit, the Group could potentially incur material impairment charges in the future.

Leases

Leases of Lessee Disclosure [Text Block]	21 Leases The Group enters into both lessee and lessor arrangements. A lease is identified when a contract (or a part of a contract) exists that conveys the right to control the use of an identified asset for a period of time in exchange for consideration. In determining whether a contract contains a lease, the Group has assessed whether there is an identifiable asset and whether it has the right to control the use of the identified asset. > Refer to “Note 2 – Recently issued accounting standards” for further information. Lessee arrangements The Group recognizes lease liabilities, which are reported as other liabilities or long-term debt, and right-of-use (ROU) assets, which are reported as other assets. Lease liabilities represent an obligation to make lease payments under the lease contract while ROU assets represent the right to use an underlying asset for the lease term. Lease liabilities and ROU assets are recognized at the lease commencement date based on the present value of future lease payments over the lease term. > Refer to “Note 20 – Other assets and other liabilities” and “Note 22 – Long-term debt”. The Group enters into leases with fixed or variable lease payments, or with lease payments that depend on an index or a referenced rate. Lease payments at lease commencement which depend on an index or a referenced rate are considered to be unavoidable and are therefore included in the lease liabilities. Other variable lease payments, as well as subsequent changes in an index or referenced rate, are excluded from the lease liabilities. The Group’s incremental borrowing rate, which is used in determining the present value of lease payments, is derived from information available at the lease commencement date. The incremental borrowing rate used for leases is a comparable rate that the Group would expect to pay if it were borrowing from a third party. The Group primarily enters into operating leases. Operating leases result in a single lease cost, calculated such that the cost of the lease is allocated over the remaining lease term on a straight-line basis. For all leases other than real estate leases, the Group does not separate lease and non-lease components. Operating lease expenses are recognized in general and administrative expenses. The Group’s finance leases are not material. For certain leases, there are options that permit the Group to extend or terminate these leases. Such options are only included in the measurement of ROU assets and lease liabilities when it is reasonably certain that the Group would exercise the extension option or would not exercise the termination option. The Group has entered into real estate and equipment leases as well as leases relating to a portfolio of residential solar panels, which are subsequently subleased. Certain real estate leases include restrictions, for example, conditions relating to naming rights or signage.

If specific criteria are met, the asset is derecognized from the balance sheet and an operating lease is recognized. During 2Q19, the Group entered into two sale-leaseback transactions in respect of own property, with terms of 10 and 13 years, respectively.

Previously, the operating lease commitments were based on the minimum contractual term of the lease. Lessor arrangements The Group de-recognizes the underlying assets and recognizes net investments in the leases of sales-type and direct financing leases, which are classified as loans. Subsequently, unearned income is amortized to interest income over the lease term using the effective interest method. For operating leases, the Group continues to recognize the underlying asset and depreciates the asset over its estimated useful life. Lease income is recognized in other income on a straight-line basis over the lease term. Consideration in a contract is allocated to each separate lease component and each non-lease component on a relative basis in proportion to the stand-alone selling price. The stand-alone selling price is the price at which a customer would purchase the component separately. The Group enters into sales-type, direct financing and operating leases for real estate and equipment as well as solar equipment. The net investment in the lease is calculated as the lease receivable plus the unguaranteed portion of the estimated residual value. The lease receivable is initially measured at the present value of the sum of the future lease payments receivable over the lease term and any portion of the estimated residual value at the end of the lease term that is guaranteed by either the lessee or an unrelated third party. The Group initially measures the unguaranteed residual value of the asset as the present value of the amount the lessor expects to derive from the underlying asset following the end of the lease term that is not guaranteed by the lessee or any other third party unrelated to the lessor. The discount rate used is the rate implicit in the lease. > Refer to “Note 18 – Loans, allowance for loan losses and credit quality” for further information on impaired loans. As of 2Q19, the Group had approximately CHF 0.8 billion in residual value guarantees associated with leases. Lease payments are recorded when due and payable by the lessee.

The Group enters into leases with fixed or variable lease payments, or with lease payments that depend on an index or a referenced rate which are included in the net investment in the lease at lease commencement, as such payments are considered unavoidable. Other variable lease payments, as well as subsequent changes in an index or referenced rate, are excluded from the net investment in the lease. For certain leases, there are options that permit the lessee to extend or renew these leases. Such options are only included in the measurement of lease receivables for sales-type and direct financing leases when it is reasonably certain that the lessee would exercise these options. Certain leases include i) termination options that allow lessees to terminate the leases within three months of the commencement date, with a notice period of 30 days; ii) termination options that allow the Group to terminate the lease but do not provide the lessee with the same option; and iii) termination penalties, options to prepay the payments for the remaining lease term or options that permit the lessee to purchase the leased asset at market value or at the greater of market value and the net present value of the remaining payments. The Group may enter into vehicle leases as a lessor with members of the Board of Directors or the Executive Board. The terms of any such leases are similar to those with third parties.

Offsetting of financial assets

Offsetting of financial assets and financial liabilities	24 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 28 – 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 2Q19 and 4Q18. 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	25 Tax The 2Q19 income tax expense of CHF 365 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 net operating losses, 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 net operating losses 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, 2019, the Group had accumulated undistributed earnings from foreign subsidiaries of CHF 11.9 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, 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 187 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 – 2011; the US – 2010; and the Netherlands – 2006.

Other non-deductible expenses 2Q19 included the net impact of CHF 54 million relating to non-deductible interest expenses (including a benefit of CHF 60 million from a previously unrecognized tax benefit) and non-deductible bank levy costs. The remaining balance included various smaller items relating to other non-deductible expenses. Changes in deferred tax valuation allowance 2Q19 included the impact of the estimated current year earnings, resulting in a decrease of valuation allowances of CHF 30 million mainly in respect of one of the Group’s operating entities in the UK and an increase of valuation allowances of CHF 38 million mainly in respect of three of the Group’s operating entities in the US, the UK and Switzerland. Lower taxed income 2Q19 primarily included the impacts related to non-taxable dividend income of CHF 17 million and non-taxable life insurance income of CHF 12 million. Other 2Q19 included a tax charge of CHF 36 million relating to the tax impact of transitional adjustments arising on the first adoption of IFRS 9 for own credit movements, CHF 30 million relating to the US base erosion and anti-abuse tax (BEAT), CHF 26 million relating to withholding taxes and CHF 7 million relating to a prior year adjustment and various smaller balances. This was partially offset by CHF 41 million relating to a beneficial earnings mix in one of the Group’s operating entities in Switzerland, CHF 15 million relating to own-credit valuation movements and CHF 12 million relating to the release of previously unrecognized tax benefits.

Pension and other post-retirement benefits	27 Pension and other post-retirement benefits The Group sponsors defined contribution pension plans, defined benefit pension plans and other post-retirement defined benefit plans. The Group contributed and recognized expenses of CHF 44 million, CHF 41 million, CHF 43 million, CHF 85 million and CHF 85 million related to its defined contribution pension plans in 2Q19, 1Q19, 2Q18, 6M19 and 6M18, respectively. > Refer to “Note 31 – Pension and other post-retirement benefits” in VI – Consolidated financial statements – Credit Suisse Group in the Credit Suisse Annual Report 2018 for further information. The Group expects to contribute CHF 429 million to the Swiss and international defined benefit plans and other post-retirement defined benefit plans in 2019. As of the end of 2Q19, CHF 242 million of contributions have been made. On April 3, 2019, Credit Suisse announced an amendment to its existing Swiss defined benefit pension plan and the introduction of a new Swiss defined contribution plan. Effective January 1, 2020, savings contributions on gross salary components exceeding a certain threshold will be credited to a new Swiss defined contribution plan and no longer paid into the lump-sum component of the existing Swiss defined benefit pension plan. In the new Swiss defined contribution plan, insured employees can select the investment strategy and will bear the investment risk. These changes resulted in a reduction of the Swiss pension plan liabilities and an increase in the overall funding surplus of the existing Swiss defined benefit pension plan of CHF 428 million (CHF 338 million, net of tax) which was recognized as a prior service credit in 2Q19. The plan amendment triggered a revaluation of plan assets and liabilities based on 1Q19 market data, resulting in an actuarial gain and an additional increase in the overall funding surplus of the Swiss defined benefit pension plan of CHF 406 million (CHF 323 million, net of tax). The total increase in the overall funding surplus of the Swiss defined benefit pension plan is reflected in Other assets – defined benefit pension and post-retirement plan assets.

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 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 9.5 billion and CHF 9.7 billion as of the end of 2Q19 and 4Q18, 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.

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.

Credit derivatives > Refer to “Note 31 – Derivatives and hedging activities” in VIII – Consolidated financial statements – Credit Suisse (Bank) in the Credit Suisse Annual Report 2018 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 9.5 billion and CHF 9.7 billion as of the end of 6M19 and 2018, 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	29 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 2018 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, 2018 to June 30, 2019 was CHF 0.5 billion. These deposit insurance guarantees were reflected in other guarantees. For the period July 1, 2019 to June 30, 2020, the Group’s share in this 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; loan-to-value ratios and other characteristics of the property, the borrower and the loan; validity of the liens securing the loans and absence of delinquent taxes or related liens; conformity to underwriting standards and completeness of documentation; and origination in compliance with law. If it is determined that representations and warranties were breached, the Group may be required to repurchase the related loans or indemnify the investors to make them whole for losses. Whether the Group will incur a loss in connection with repurchases and make whole payments depends on: the extent to which claims are made; the validity of such claims made within the statute of limitations (including the likelihood and ability to enforce claims); whether the Group can successfully claim against parties that sold loans to the Group and made representations and warranties to the Group; the residential real estate market, including the number of defaults; and whether the obligations of the securitization vehicles were guaranteed or insured by third parties. Repurchase claims on residential mortgage loans sold that are subject to arbitration or litigation proceedings, or become so during the reporting period, are not included in this Guarantees and commitments disclosure but are addressed in litigation and related loss contingencies and provisions. The Group is involved in litigation relating to representations and warranties on residential mortgages sold. > Refer to “Note 33 – 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 2018 for a description of these guarantees.

Transfers of financial assets and variable interest entities	30 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), residential mortgage-backed securities (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 securities. Typically, certificates issued out of an existing securitization vehicle are sold into a newly created and separate securitization vehicle. Often, these re-securitizations are initiated in order to re-securitize an existing security to give the investor an investment with different risk ratings or characteristics. The Group also uses SPEs for other asset-backed financings relating to client-driven activity and for Group tax or regulatory purposes. Types of structures included in this category include managed collateralized loan obligations (CLOs), CLOs, leveraged finance, repack and other types of transactions, including life insurance structures, emerging market structures set up for financing, loan participation or loan origination purposes, and other alternative structures created for the purpose of investing in venture capital-like investments. CLOs are collateralized by loans transferred to the CLO vehicle and pay a return based on the returns on the loans. Leveraged finance structures are used to assist in the syndication of certain loans held by the Group, while repack structures are designed to give a client collateralized exposure to specific cash flows or credit risk backed by collateral purchased from the Group. In these asset-backed financing structures, investors typically only have recourse to the collateral of the SPE and do not have recourse to the Group’s assets. When the Group transfers assets into an SPE, it must assess whether that transfer is accounted for as a sale of the assets. Transfers of assets may not meet sale requirements if the assets have not been legally isolated from the Group and/or if the Group’s continuing involvement is deemed to give it effective control over the assets. If the transfer is not deemed a sale, it is instead accounted for as a secured borrowing, with the transferred assets as collateral. Gains and losses on securitization transactions depend, in part, on the carrying values of mortgages and loans involved in the transfer and are allocated between the assets sold and any beneficial interests retained according to the relative fair values at the date of sale. The Group does not retain material servicing responsibilities from securitization activities. The following table provides the gains or losses and proceeds from the transfer of assets relating to 6M19 and 6M18 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 2018 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 2Q19 and 4Q18, regardless of when the transfer of assets occurred. Principal amounts outstanding and total assets of SPEs resulting from continuing involvement end of 2Q19 4Q18 CHF million CMBS Principal amount outstanding 21,607 25,330 Total assets of SPE 31,491 35,760 RMBS Principal amount outstanding 48,923 40,253 Total assets of SPE 49,857 41,242 Other asset-backed financings Principal amount outstanding 22,782 23,036 Total assets of SPE 47,272 47,542 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 31 – 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 2Q19 and 4Q18.

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 2Q19 and 4Q18. > Refer to “Note 32 – Assets pledged and collateral” for further information. Carrying amounts of transferred financial assets and liabilities where sale treatment was not achieved end of 2Q19 4Q18 CHF million Other asset-backed financings Trading assets 276 255 Liability to SPE, included in other liabilities (276) (255) Securities sold under repurchase agreements and securities lending transactions accounted for as secured borrowings For securities sold under repurchase agreements and securities lending transactions accounted for as secured borrowings, US GAAP requires the disclosure of the collateral pledged and the associated risks to which a transferor continues to be exposed after the transfer. 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 2Q19 and 4Q18.

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 2018 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. 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. The CP conduit 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 to the CP conduit 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 114 days as of the end of 2Q19. Alpine 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, car loans and leases, small business loans and commercial leases. The Group’s 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 a lack of liquidity in the CP market such that the CP conduit cannot refinance its obligations or, in some cases, 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’s economic risks associated with the CP conduit 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 2Q19 and 4Q18.

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 30 – Financial instruments” for information on fair value hierarchy levels.

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. 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. The CP conduit 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 to the CP conduit 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 the conduit’s outstanding CP was approximately 114 days as of the end of 6M19. Alpine was rated A-1(sf) by Standard & Poor’s and P-1(sf) by Moody’s and had exposures mainly in had exposures mainly in reverse repurchase agreements with a Group entity, consumer loans, car loans and leases, small business loans and commercial leases. The Bank’s 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 a lack of liquidity in the CP market such that the CP conduit cannot refinance its obligations or, in some cases, 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.

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. Transfers in and out of level 3 Transfers into level 3 assets during 6M19 were CHF 1,151 million, primarily from trading assets and loans. These transfers were primarily in the financing, equity derivatives and credit businesses due to limited observability of pricing data. Transfers out of level 3 assets during 6M19 were CHF 2,200 million, primarily in trading assets and loans. These transfers were primarily in the fixed income, equity derivatives and financing businesses due to increased observability of pricing data and increased availability of pricing information from external providers. Transfers into level 3 assets during 2Q19 were CHF 450 million, primarily from trading assets. These transfers were primarily in the financing, equity derivatives and credit businesses due to limited observability of pricing data. Transfers out of level 3 assets during 2Q19 were CHF 1,111 million, primarily in trading assets and loans. These transfers were primarily in the fixed income, financing and equity derivatives businesses due to increased observability of pricing data and increased availability of pricing information from external providers. 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, contingent probability, correlation, 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 contingent probability, credit spread, gap risk or market implied life expectancy would increase the fair value. An increase in the significant unobservable inputs buyback probability, correlation, discount rate, fund gap risk, fund NAV, funding spread, mean reversion, mortality rate, prepayment rate, price or volatility 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, 2019
Litigation	33 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 financial statements – Credit Suisse Group in the Credit Suisse Annual Report 2018 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 1.4 billion. In 2Q19, the Group recorded net litigation provisions of CHF 73 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 The amounts disclosed below do not reflect actual realized plaintiff losses to date or anticipated future litigation exposure. Rather, unless otherwise stated, these amounts reflect the original unpaid principal balance amounts as alleged in these actions and do not include any reduction in principal amounts since issuance. Individual investor actions On May 16, 2019, following a settlement, the Circuit Court of Montgomery County, Alabama presiding in the action brought by the Federal Deposit Insurance Corporation, as receiver for Colonial Bank, dismissed with prejudice all claims against Credit Suisse Securities (USA) LLC and its affiliates relating to approximately USD 139 million of RMBS at issue.

OTC trading cases On June 18, 2019, in the consolidated multi-district litigation relating to interest rate swaps, defendants filed an opposition to plaintiffs’ motion for class certification. MPS On June 11, 2019, following a settlement, the Civil Court of Milan, Italy dismissed all claims against Credit Suisse Securities (Europe) Limited (CSSEL) brought by the Monte dei Paschi di Siena Foundation (Foundation) relating to the fairness opinions CSSEL and Banca Leonardo & Co S.p.A. delivered to the Foundation in connection with the EUR 9 billion acquisition of Banca Antonveneta S.p.A. by Banca Monte dei Paschi di Siena S.p.A. in 2008. Customer account matters On June 26, 2019, the Criminal Court of Appeals of Geneva ruled in the appeal of the judgment against the former relationship manager, upholding the main findings of the Geneva criminal court. On April 29, 2019, the plaintiffs appealed the decision of the Singapore High Court only with respect to their action against the Credit Suisse affiliate. On June 21, 2019, the plaintiffs discontinued their action against Credit Suisse AG in the Singapore courts. On May 3, 2019, the plaintiffs filed a notice of abandonment of appeal in the Court of Appeal of New Zealand. Mozambique matter On May 20, 2019 and July 19, 2019, two former Credit Suisse employees indicted by the United States Attorney for the Eastern District of New York pleaded guilty to accepting improper personal benefit in connection with financing transactions carried out with two Mozambique state enterprises. On June 25, 2019, certain Credit Suisse entities were served with civil proceedings in the English High Court by the Republic of Mozambique. Write-downs litigation On May 16, 2019, 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’s American Depositary Receipts, the SDNY denied defendants’ motion for reconsideration of the court’s February 19, 2019 denial of defendants’ motion to dismiss. ETN-related litigation On May 16, 2019, in the individual action brought 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), defendants filed a motion to dismiss. On June 3, 2019, Credit Suisse Group AG and certain affiliates and executives were named in a separate individual action brought in the SDNY by a purchaser of XIV ETNs, which asserts claims similar to those brought in the consolidated class action complaint as well as additional claims under New York and Pennsylvania state law.

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

PSA utilizes the 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.
