Introduction
General
The purpose of this Pillar 3 report is to provide updated information as of June 30, 2015 on our implementation of the Basel capital framework and risk assessment processes in accordance with the Pillar 3 requirements. This document should be read in conjunction with the Credit Suisse Annual Report 2014 and the Credit Suisse 1Q15 and 2Q15 Financial Report, which includes important information on regulatory capital and risk management (specific references have been made herein to these documents).
In addition to Pillar 3 disclosures we disclose the way we manage our risks for internal management purposes in the Annual Report.
> Refer to “Risk management” (pages 126 to 160) in III – Treasury, Risk, Balance sheet and Off-balance sheet in the Credit Suisse Annual Report 2014 for further information regarding the way we manage risk including economic capital as a Group-wide risk management tool.
Certain reclassifications may be made to prior periods to conform to the current period’s presentation.
The Pillar 3 report is produced and published semi-annually, in accordance with Swiss Financial Market Supervisory Authority FINMA (FINMA) requirements.
This report was verified and approved internally in line with our Pillar 3 disclosure policy. The Pillar 3 report has not been audited by the Group’s external auditors. However, it also includes information that is contained within the audited consolidated financial statements as reported in the Credit Suisse Annual Report 2014.
Regulatory development
On January 28, 2015, the Basel Committee on Banking Supervision (BCBS) issued the final standard for the revised Pillar 3 disclosure requirements. The revised disclosure requirements will enable market participants to compare bank’s disclosure of risk-weighted assets. The revisions focus on improving the transparency of the internal model-based approaches that banks use to calculate minimum regulatory capital requirements. The revised requirements will be effective for the year-end 2016 financial reporting.
Location of disclosure
This report provides the Basel III Pillar 3 disclosures to the extent that these required Pillar 3 disclosures are not included in the Credit Suisse Annual Report 2014 and the Credit Suisse 2Q15 Financial Report.

Scope of application
The highest consolidated entity in the Group to which the Basel III framework applies is Credit Suisse Group.
> Refer to “Regulation and supervision” (pages 26 to 38) in I – Information on the company and to “Capital management” (pages 108 to 125) in III – Treasury, Risk, Balance sheet and Off-balance sheet in the Credit Suisse Annual Report 2014 for further information on regulation.
Principles of consolidation
For financial reporting purposes, our consolidation principles comply with accounting principles generally accepted in the US (US GAAP). For capital adequacy reporting purposes, however, entities that are not active in banking and finance are not subject to consolidation (i.e. insurance, real estate and commercial companies). Also, FINMA does not require to consolidate private equity and other fund type vehicles for capital adequacy reporting. Further differences in consolidation principles between US GAAP and capital adequacy reporting relate to special purpose entities (SPEs) that are consolidated under a control-based approach for US GAAP but are assessed under a risk-based approach for capital adequacy reporting. The investments into such entities, which are not material to the Group, are treated in accordance with the regulatory rules and are either subject to a risk-weighted capital requirement or a deduction from regulatory capital.
All significant equity method investments represent investments in the capital of banking, financial and insurance (BFI) entities and are subject to a threshold calculation in accordance with the Basel framework.
Restrictions on transfer of funds or regulatory capital
We do not believe that legal or regulatory restrictions constitute a material limitation on the ability of our subsidiaries to pay dividends or our ability to transfer funds or regulatory capital within the Group.
Capital deficiencies
The Group’s subsidiaries which are not included in the regulatory consolidation did not report any capital deficiencies in 6M15.
Risk management oversight
Fundamental to our business is the prudent taking of risk in line with our strategic priorities. The primary objectives of risk management are to protect our financial strength and reputation, while ensuring that capital is well deployed to support business activities and grow shareholder value. Our risk management framework is based on transparency, management accountability and independent oversight. Risk measurement models are reviewed by the Model Risk Management team, an independent validation function, and regularly presented to and approved by the relevant oversight committee.
> Refer to “Risk management oversight” (pages 127 to 130), “Risk appetite framework” (pages 130 to 132) and “Risk coverage and management” (pages 133 to 136) in III – Treasury, Risk, Balance sheet and Off-balance sheet – Risk management in the Credit Suisse Annual Report 2014 for information on risk management oversight including risk culture, risk governance, risk organization, risk types and risk appetite and risk limits.
The Group is exposed to several key banking risks such as:
Credit risk (refer to section “Credit risk” on pages 14 to 35);
Market risk (refer to section “Market risk” on pages 36 to 42);
Interest rate risk in the banking book (refer to section “Interest rate risk in the banking book” on pages 43 to 44); and
Operational risk (refer to section “Capital” on page 9).

Capital
Regulatory capital framework
Effective January 1, 2013, the Basel III framework was implemented in Switzerland along with the Swiss “Too Big to Fail” legislation and regulations thereunder (Swiss Requirements). Our related disclosures are in accordance with our current interpretation of such requirements, including relevant assumptions. Changes in the interpretation of these requirements in Switzerland or in any of our assumptions or estimates could result in different numbers from those shown in this report. Also, our capital metrics fluctuate during any reporting period in the ordinary course of business.
> Refer to “Capital management” (pages 108 to 125) in III – Treasury, Risk, Balance sheet and Off-balance sheet in the Credit Suisse Annual Report 2014 for further information.
Capital structure under Basel III
The BCBS, the standard setting committee within the Bank for International Settlements (BIS), issued the Basel III framework, with higher minimum capital requirements and conservation and countercyclical buffers, revised risk-based capital measures, a leverage ratio and liquidity standards. The framework was designed to strengthen the resilience of the banking sector and requires banks to hold more capital, mainly in the form of common equity. The new capital standards are being phased in from 2013 through 2018 and are fully effective January 1, 2019 for those countries that have adopted Basel III.
> Refer to the table “Basel III phase-in requirements for Credit Suisse” (page 53) in II – Treasury, risk, balance sheet and off-balance sheet – Capital management – Regulatory capital framework in the Credit Suisse 2Q15 Financial Report for capital requirements and applicable effective dates during the phase-in period.
Under Basel III, the minimum common equity tier 1 (CET1) requirement is 4.5% of risk-weighted assets. In addition, a 2.5% CET1 capital conservation buffer is required to absorb losses in periods of financial and economic stress.
A progressive buffer between 1% and 2.5% (with a possible additional 1% surcharge) of CET1, depending on a bank’s systemic importance, is an additional capital requirement for global systemically important banks (G-SIB). The Financial Stability Board has identified us as a G-SIB and requires us to maintain a 1.5% progressive buffer.
In addition to the CET1 requirements, there is also a requirement for 1.5% additional tier 1 capital and 2% tier 2 capital. These requirements may also be met with CET1 capital. To qualify as additional tier 1 under Basel III, capital instruments must provide for principal loss absorption through a conversion into common equity or a write-down of principal feature. The trigger for such conversion or write-down must include a CET1 ratio of at least 5.125%.
Basel III further provides for a countercyclical buffer that could require banks to hold up to 2.5% of CET1 or other capital that would be available to fully absorb losses. This requirement is expected to be imposed by national regulators where credit growth is deemed to be excessive and leading to the build-up of system-wide risk.
Capital instruments that do not meet the strict criteria for inclusion in CET1 are excluded. Capital instruments that would no longer qualify as tier 1 or tier 2 capital will be phased out.
Swiss Requirements
The legislation implementing the Basel III framework in Switzerland in respect of capital requirements for systemically relevant banks goes beyond Basel III’s minimum standards, including requiring us, as a systemically relevant bank, to have the following minimum, buffer and progressive components.
> Refer to the chart “Swiss capital and leverage ratio phase-in requirements for Credit Suisse” (page 54) in II – Treasury, risk, balance sheet and off-balance sheet – Capital management – Regulatory capital framework in the Credit Suisse 2Q15 Financial Report for Swiss capital requirements and applicable effective dates during the phase-in period.
The minimum requirement of CET1 capital is 4.5% of risk-weighted assets.
The buffer requirement is 8.5% and can be met with additional CET1 capital of 5.5% of risk-weighted assets and a maximum of 3% of high-trigger capital instruments. High-trigger capital instruments must convert into common equity or be written off if the CET1 ratio falls below 7%.
The progressive component requirement is dependent on our size (leverage ratio exposure) and the market share of our domestic systemically relevant business. Effective in 2015, FINMA set our progressive component requirement at 4.05% for 2019. On June 30, 2015, FINMA notified us that, effective in 2016, the progressive component requirement for 2019 will be increased from 4.05% to 5.07% due to the latest assessment of our relevant market share. The progressive component requirement may be met with CET1 capital or low-trigger capital instruments. In order to qualify, low-trigger capital instruments must convert into common equity or be written off if the CET1 ratio falls below a specified percentage, the lowest of which may be 5%. In addition, until the end of 2017, the progressive component requirement may also be met with high-trigger capital instruments. Both high and low-trigger capital instruments must comply with the Basel III minimum requirements for tier 2 capital (including subordination, point-of-non-viability loss absorption and minimum maturity).
Similar to Basel III, the Swiss Requirements include a supplemental countercyclical buffer of up to 2.5% of risk-weighted assets that can be activated during periods of excess credit growth. Effective September 2013, the countercyclical capital buffer was activated and initially required banks to hold CET1 capital in the amount of 1% of their risk-weighted assets pertaining to mortgages that finance residential property in Switzerland. In January 2014, upon the request of the Swiss National Bank, the
5

Swiss Federal Council increased the countercyclical buffer from 1% to 2%, effective June 30, 2014. As of the end of 2Q15, our countercyclical buffer, which applies pursuant to both BIS and FINMA requirements, was CHF 337 million, which is equivalent to an additional requirement of 0.1% of CET1 capital.
In 2013, FINMA introduced increased capital charges for mortgages that finance owner occupied residential property in Switzerland (mortgage multiplier) to be phased in through January 1, 2019. The mortgage multiplier applies for purposes of both BIS and FINMA requirements.
In December 2013, FINMA issued a decree (FINMA Decree) specifying capital adequacy requirements for the Bank, on a stand-alone basis (Bank parent company), and the Bank and the Group, each on a consolidated basis, as systemically relevant institutions.
> Refer to “Capital management” (pages 108 to 125) in III – Treasury, Risk, Balance sheet and Off-balance sheet in the Credit Suisse Annual Report 2014 and “Capital management” (pages 52 to 67) in II – Treasury, risk, balance sheet and off-balance sheet in the Credit Suisse 2Q15 Financial Report for information on our capital structure, eligible capital and shareholders’ equity, capital adequacy and leverage ratio requirements under Basel III and Swiss Requirements.
Description of regulatory approaches
The Basel framework provides a range of options for determining the capital requirements in order to allow banks and supervisors the ability to select approaches that are most appropriate. In general, Credit Suisse has adopted the most advanced approaches, which align with the way risk is internally managed. The Basel framework focuses on credit risk, market risk, operational risk and interest rate risk in the banking book. The regulatory approaches for each of these risk exposures and the related disclosures under Pillar 3 are set forth below.
Credit risk
Credit risk by asset class
The Basel framework permits banks a choice between two broad methodologies in calculating their capital requirements for credit risk by asset class, the internal ratings-based (IRB) approach or the standardized approach. Off-balance-sheet items are converted into credit exposure equivalents through the use of credit conversion factors (CCF).
The majority of our credit risk by asset class is with institutional counterparties (sovereigns, other institutions, banks and corporates) and arises from lending and trading activity in the Investment Banking and Private Banking & Wealth Management divisions. The remaining credit risk by asset class is with retail counterparties and mostly arises in the Private Banking & Wealth Management division from residential mortgage loans and other secured lending, including loans collateralized by securities.
> Refer to “Credit risk by asset class” in section “Credit risk” on pages 14 to 29 for further information.
Advanced-internal ratings-based approach
Under the IRB approach, risk weights are determined by using internal risk parameters and applying an asset value correlation multiplier uplift where exposures are to financial institutions meeting regulatory defined criteria. We have received approval from FINMA to use, and have fully implemented, the advanced-internal ratings-based (A-IRB) approach whereby we provide our own estimates for probability of default (PD), loss given default (LGD) and exposure at default (EAD).
PD parameters capture the risk of a counterparty defaulting over a one-year time horizon. PD estimates are mainly derived from models tailored to the specific business of the respective obligor. The models are calibrated to the long run average of annual internal or external default rates where applicable. For portfolios with a small number of empirical defaults (less than 20), low default portfolio techniques are used.
LGD parameters consider seniority, collateral, counterparty industry and in certain cases fair value markdowns. LGD estimates are based on an empirical analysis of historical loss rates and are calibrated to reflect time and cost of recovery as well as economic downturn conditions. For much of the Private Banking & Wealth Management loan portfolio, the LGD is primarily dependent upon the type and amount of collateral pledged. The credit approval and collateral monitoring process are based on loan-to-value limits. For mortgages (residential or commercial), recovery rates are differentiated by type of property.
EAD is either derived from balance sheet values or by using models. EAD for a non-defaulted facility is an estimate of the expected exposure upon default of the obligor. Estimates are derived based on a CCF approach using default-weighted averages of historical realized conversion factors on defaulted loans by facility type. Estimates are calibrated to capture negative operating environment effects.
We have received approval from FINMA to use the internal model method for measuring counterparty risk for the majority of our derivative and secured financing exposures.
Risk weights are calculated using either the PD/LGD approach or the supervisory risk weights (SRW) approach for certain types of specialized lending.
Standardized approach
Under the standardized approach, risk weights are determined either according to credit ratings provided by recognized external credit assessment institutions or, for unrated exposures, by using the applicable regulatory risk weights. Less than 10% of our credit risk by asset class is determined using this approach.
6

Securitization risk in the banking book
For securitizations, the regulatory capital requirements are calculated using IRB approaches (the RBA and the SFA) and the standardized approach in accordance with the prescribed hierarchy of approaches in the Basel regulations. External ratings used in regulatory capital calculations for securitization risk exposures in the banking book are obtained from Fitch, Moody’s, Standard & Poor’s or Dominion Bond Rating Service.
> Refer to “Securitization risk in the banking book” in section “Credit risk” on pages 30 to 34 for further information on the IRB approaches and the standardized approach.
7

Equity type securities in the banking book
For equity type securities in the banking book except for significant investments in BFI entities, risk weights are determined using the IRB Simple approach based on the equity sub-asset type (listed equity and all other equity positions). Significant investments in BFI entities (i.e. investments in the capital of BFI entities that are outside the scope of regulatory consolidation, where the Group owns more than 10% of the issued common share capital of the entity) are subject to a threshold treatment as outlined below in the section “Exposures below 15% threshold”. Where equity type securities represent non-significant investments in BFI entities (i.e., investments in the capital of BFI entities that are outside the scope of regulatory consolidation, where the Group does not own more than 10% of the issued common share capital of the entity), a threshold approach is applied that compares the total amount of non-significant investments in BFI entities (considering both trading and banking book positions) to a 10% regulatory defined eligible capital amount. The amount above the threshold is phased-in as a capital deduction and the amount below the threshold continues to be risk-weighted according to the relevant trading book and banking book approaches.
> Refer to “Equity type securities in the banking book” in section “Credit risk” on pages 34 to 35 for further information.
Credit valuation adjustment risk
Basel III introduced a new regulatory capital charge, Credit Valuation Adjustment (CVA), designed to capture the risk associated with potential mark-to-market losses associated with the deterioration in the creditworthiness of a counterparty. 
Under Basel III, banks are required to calculate capital charges for CVA under either the Standardized CVA approach or the Advanced CVA approach (ACVA). The CVA rules stipulate that where banks have permission to use market risk Value-at-Risk (VaR) and counterparty risk Internal Models Method (IMM), they are to use the ACVA unless their regulator decides otherwise. FINMA has confirmed that the ACVA should be used for both IMM and non-IMM exposures.
The regulatory CVA capital charge applies to all counterparty exposures arising from over-the-counter (OTC) derivatives, excluding those with central counterparties (CCP). Exposures arising from Securities Financing Transactions (SFT) are not required to be included in the CVA charge unless they could give rise to a material loss. FINMA has confirmed that Credit Suisse can exclude these exposures from the regulatory capital charge.
Central counterparties risk
The Basel III framework provides specific requirements for exposures the Group has to CCP arising from OTC derivatives, exchange-traded derivative transactions and SFT. Exposures to CCPs which are considered to be qualifying CCPs by the regulator will receive a preferential capital treatment compared to exposures to non-qualifying CCPs.
The Group can incur exposures to CCPs as either a clearing member (house or client trades), or as a client of another clearing member. Where the Group acts as a clearing member of a CCP on behalf of its client (client trades), it incurs an exposure to its client as well as an exposure to the CCP. Since the exposure to the client is to be treated as a bilateral trade, the risk-weighted assets from these exposures are represented under “credit risk by asset class”. Where the Group acts as a client of another clearing member the risk-weighted assets from these exposures are also represented under “credit risk by asset class”.
The exposures to CCP (represented as “Central counterparties (CCP) risks”) consist of trade exposure, default fund exposure and contingent exposure based on trade replacement due to a clearing member default. While the trades exposure includes the current and potential future exposure of the clearing member (or a client) to a CCP arising from the underlying transaction and the initial margin posted to the CCP, the default fund exposure is arising from default fund contributions to the CCP.
Settlement risk
Regulatory fixed risk weights are applied to settlement exposures. Settlement exposures arise from unsettled or failed transactions where cash or securities are delivered without a corresponding receipt.
Exposures below 15% threshold
Significant investments in BFI entities, mortgage servicing rights and deferred tax assets that arise from temporary differences are subject to a threshold approach, whereby individual amounts are compared to a 10% threshold of regulatory defined eligible capital. In addition amounts below the individual 10% thresholds are aggregated and compared to a 15% threshold of regulatory defined eligible capital. The amount that is above the 10% threshold is phased-in as a CET1 deduction. The amount above the 15% threshold is phased-in as a CET1 deduction and the amount below is risk weighted at 250%.
Other items
Other items include risk-weighted assets related to immaterial portfolios for which we have received approval from FINMA to apply a simplified Institute Specific Direct Risk Weight as well as risk-weighted assets related to items that were risk-weighted under Basel II.5 and are phased in as capital deductions under Basel III.
Market risk
We use the advanced approach for calculating the capital requirements for market risk for the majority of our exposures. The following advanced approaches are used: the internal models approach (IMA) and the standardized measurement method (SMM).
We use the standardized approach to determine our market risk for a small population of positions which represent an immaterial proportion of our overall market risk exposure.
> Refer to section “Market risk” on pages 36 to 42 for further information on market risk.
8

Internal models approach
The market risk IMA framework includes regulatory Value-at-Risk (VaR), stressed VaR, risks not in VaR (RNIV) and Incremental Risk Charge (IRC). In 2014 Comprehensive Risk Measure was discontinued due to the small size of the correlation trading portfolio. We now use the standard rules for this portfolio.
Regulatory VaR, stressed VaR and risks not in VaR
We have received approval from FINMA, as well as from certain other regulators of our subsidiaries, to use our VaR model to calculate trading book market risk capital requirements under the IMA. We apply the IMA to the majority of the positions in our trading book. We continue to receive regulatory approval for ongoing enhancements to the VaR methodology, and the VaR model is subject to regular reviews by regulators. Stressed VaR replicates a VaR calculation on the Group’s current portfolio taking into account a one-year observation period relating to significant financial stress and helps to reduce the pro-cyclicality of the minimum capital requirements for market risk. The VaR model does not cover all identified market risk types and as such we have also adopted a RNIV category which was approved by FINMA in 2012.
Incremental Risk Charge
The IRC capitalizes issuer default and migration risk in the trading book, such as bonds or credit default swaps, but excludes securitizations and correlation trading. We have received approval from FINMA, as well as from certain other regulators of our subsidiaries, to use our IRC model. We continue to receive regulatory approval for ongoing enhancements to the IRC methodology, and the IRC model is subject to regular reviews by regulators.
The IRC model assesses risk at 99.9% confidence level over a one year time horizon assuming that positions are sold and replaced one or more times, depending on their liquidity which is modeled by the liquidity horizon. The portfolio loss distribution is estimated using an internally developed credit portfolio model designed to the regulatory requirements.
The liquidity horizon represents time required to sell the positions or hedge all material risk covered by the IRC model in a stressed market. Liquidity horizons are modelled according to the requirements imposed by Basel III guidelines.
The IRC model and liquidity horizon methodology have been validated by the Model Risk Management team in accordance with the firms validation umbrella policy and Risk Model Validation Sub-Policy for IRC.
Standardized measurement method
We use the SMM which is based on the ratings-based approach (RBA) and the supervisory formula approach (SFA) for securitization purposes (see also Securitization risk in the banking book) and other supervisory approaches for trading book securitization positions covering the approach for nth-to-default products and portfolios covered by the weighted average risk weight approach.
> Refer to “Securitization risk in the trading book” in section “Market risk” on pages 37 to 42 for further information on the standardized measurement method and other supervisory approaches.
Operational risk
We have used an internal model to calculate the regulatory capital requirement for operational risk under the Advanced Measurement Approach (AMA) since 2008. In 2014, we introduced an enhanced internal model that incorporated recent developments regarding operational risk measurement methodology and associated regulatory guidance. FINMA approved the revised model for calculating the regulatory capital requirement for operational risk with effect from January 1, 2014. We view the revised model as a significant enhancement to our capability to measure and understand the operational risk profile of the Group that is also more conservative compared with the previous approach.
The model is based on a loss distribution approach that uses historical data on internal and relevant external losses of peers to generate frequency and severity distributions for a range of potential operational risk loss scenarios, such as an unauthorized trading incident or a material business disruption. Business experts and senior management review, and may adjust, the parameters of these scenarios to take account of business environment and internal control factors, such as risk and control self-assessment results and risk and control indicators, to provide a forward-looking assessment of each scenario. The AMA capital calculation approved by FINMA includes all litigation-related provisions and also an add-on component relating to the aggregate range of reasonably possible litigation losses that are disclosed in our financial statements but are not covered by existing provisions. Insurance mitigation is included in the regulatory capital requirement for operational risk where appropriate, by considering the level of insurance coverage for each scenario and incorporating haircuts as appropriate. The internal model then uses the adjusted parameters to generate an overall loss distribution for the Group over a one-year time horizon. The AMA capital requirement represents the 99.9th percentile of this overall loss distribution. The AMA capital requirement is allocated to businesses using a risk-sensitive approach that is designed to be forward looking and incentivize appropriate risk management behaviors.

Non-counterparty-related risk
Regulatory fixed risk weights are applied to non-counterparty-related exposures. Non-counterparty-related exposures arise from holdings of premises and equipment, real estate and investments in real estate entities.

BIS capital metrics
Regulatory capital and ratios
Regulatory capital is calculated and managed according to Basel regulations and used to determine BIS ratios. BIS ratios compare eligible CET1 capital, tier 1 capital and total capital with BIS risk-weighted assets.
> Refer to “Risk-weighted assets” (pages 54 to 55) in II – Treasury, risk, balance sheet and off-balance sheet – Capital management – BIS capital metrics in the Credit Suisse 1Q15 Financial Report and “Risk-weighted assets” (pages 58 to 59) in II – Treasury, risk, balance sheet and off-balance sheet – Capital management in the Credit Suisse 2Q15 Financial Report for information on risk-weighted assets movements in 6M15.

Credit risk
General
Credit risk consists of the following categories:
Credit risk by asset class
Securitization risk in the banking book
Equity type securities in the banking book
CVA risk
Exposures below 15% threshold
CCP risk
Settlement risk
Other items
> Refer to “Credit risk” (pages 139 to 141 and pages 152 to 160) in III – Treasury, Risk, Balance sheet and Off-balance sheet – Risk management in the Credit Suisse Annual Report 2014 for information on our credit risk management approach, ratings and risk mitigation and impaired exposures and allowances.
Credit risk by asset class
General
For regulatory purposes, we categorize our exposures into asset classes with different underlying risk characteristics including type of counterparty, size of exposure and type of collateral. The asset class categorization is driven by regulatory rules from the Basel framework.
The following table presents the description of credit risk by asset class under the Basel framework (grouped as either institutional or retail) and the related regulatory approaches used.
Credit risk by asset class - Overview
Asset class Description Approaches
Institutional credit risk (mostly in the Investment Banking division)   
Sovereigns Exposures to central governments, central banks, BIS, the International
Monetary Fund, the European Central Bank and eligible Multilateral
Development Banks (MDB).
PD/LGD for most portfolios
Standardized for banking book treasury liquidity positions
and other assets
Other institutions Exposures to public bodies with the right to raise taxes or whose
liabilities are guaranteed by a public sector entity.
PD/LGD for most portfolios
Standardized for banking book treasury liquidity positions
and other assets
Banks Exposures to banks, securities firms, stock exchanges and those MDB
that do not qualify for sovereign treatment.

PD/LGD for most portfolios
SRW for unsettled trades
Standardized for banking book treasury liquidity positions
and other assets
Corporates Exposures to corporations (except small businesses) and public sector
entities with no right to raise taxes and whose liabilities are not
guaranteed by a public entity. The Corporate asset class also includes
specialized lending, in which the lender looks primarily to a single source
of revenues to cover the repayment obligations and where only the
financed asset serves as security for the exposure (e.g., income producing
real estate or commodities finance).
PD/LGD for most portfolios
SRW for Investment Banking specialized lending exposures
Standardized for banking book treasury liquidity positions
and other assets


Retail credit risk (mostly in the Private Banking & Wealth Management division)   
Residential mortgages Includes exposures secured by residential real estate collateral occupied
or let by the borrower.
PD/LGD
Qualifying revolving retail Includes credit card receivables and overdrafts. PD/LGD
Other retail Includes loans collateralized by securities, consumer loans,
leasing and small business exposures.
PD/LGD
Standardized for other assets
Other credit risk   
Other exposures Includes exposures with insufficient information to treat under the
A-IRB approach or to allocate under the Standardized approach into
any other asset class.

Rating models
The majority of the credit rating models used in Credit Suisse are developed internally by Credit Analytics, a specialized unit in Credit Risk Management (CRM). These models are independently validated by Model Risk Management team prior to use in the Basel III regulatory capital calculation, and thereafter on a regular basis. Credit Suisse also use models purchased from recognized data and model providers (e.g. credit rating agencies). These models are owned by Credit Analytics and are validated internally and follow the same governance process as models developed internally.
All new or material changes to rating models are subject to a robust governance process. Post development and validation of a rating model or model change, the model is taken through a number of committees where model developers, validators and users of the models discuss the technical and regulatory aspects of the model. The relevant committees opine on the information provided and decide to either approve or reject the model or model change. The ultimate decision making committee is the Risk Processes and Standards Committee (RPSC). The responsible Executive Board Member for the RPSC is the Chief Risk Officer. The RPSC sub-group responsible for credit risk models is the Credit Methodology Steering Committee (CMSC). RPSC or CMSC also review and monitor the continued use of existing models on an annual basis.

The following table provides an overview of the main PD and LGD models used by Credit Suisse. It reflects the portfolio segmentation from a credit risk model point of view, showing the risk-weighted assets, type and number of the most significant models, and the loss period available for model development by portfolio. As the table follows an internal risk segmentation and captures the most significant models only, these figures do not match regulatory asset class or other A-IRB based segmentation.

Model development
The techniques to develop models are carefully selected by Credit Analytics to meet industry standards in the banking industry as well as regulatory requirements. The models are developed to exhibit “through-the-cycle” characteristics, reflecting a probability of default in a 12 month period across the credit cycle.
All models have clearly defined model owners who have primary responsibility for development, enhancement, review, maintenance and documentation. The models have to pass statistical performance tests, where feasible, followed by usability tests by designated CRM experts to proceed to formal approval and implementation. The development process of a new model is thoroughly documented and foresees a separate schedule for model updates.
The level of calibration of the models is based on a range of inputs, including internal and external benchmarks where available. Additionally, the calibration process ensures that the estimated calibration level accounts for variations of default rates through the economic cycle and that the underlying data contains a representative mix of economic states. Conservatism is incorporated in the model development process to compensate for any known or suspected limitations and uncertainties.
Model validation
Model validation for risk capital models is performed by the Model Risk Management function. Model governance is subject to clear and objective internal standards as outlined in the Model Risk Management policy and the Risk Model Validation Policy. The governance framework ensures a consistent and meaningful approach for the validation of models in scope across the bank. All models whose outputs fall into the scope of the Basel internal model framework are subject to full independent validation. Externally developed models are subject to the same governance and validation standards as internal models.
The governance process requires each in scope model to be validated and approved before go-live; the same process is followed for material changes to an existing model. Existing models
18

are subject to an ongoing governance process which requires each model to be periodically validated and the performance to be monitored annually. The validation process is a comprehensive quantitative and qualitative assessment with goals that include:
to confirm that the model remains conceptually sound and the model design is suitable for its intended purpose;
to verify that the assumptions are still valid and weaknesses and limitations are known and mitigated;
to determine that the model outputs are accurate compared to realized outcome;
to establish whether the model is accepted by the users and used as intended with appropriate data governance;
to check whether a model is implemented correctly;
to ensure that the model is fully transparent and sufficiently documented.
To meet these goals, models are validated against a series of quantitative and qualitative criteria. Quantitative analyses may include a review of model performance (comparison of model output against realized outcome), calibration accuracy against the longest time series available, assessment of a model’s ability to rank order risk and performance against available benchmarks. Qualitative assessment typically includes a review of the appropriateness of the key model assumptions, the identification of the model limitations and their mitigation, and ensuring appropriate model use. The modeling approach is re-assessed in light of developments in the academic literature and industry practice.
Results and conclusions are presented to senior risk management including the RPSC; shortcomings and required improvements identified during validation must be remediated within an agreed deadline. The Model Risk Management function is independent of model developers and users and has the final say on the content of each validation report.
Stress testing of parameters
The potential biases in PD estimates in unusual market conditions are accounted for by the use of long run average estimates. Credit Suisse additionally uses stress-testing when back-testing PD models. When predefined thresholds are breached during back-testing, a review of the calibration level is undertaken. For LGD/CCF calibration stress testing is applied in defining Downturn LGD/CCF values, reflecting potentially increased losses during stressed periods.
Descriptions of the rating processes
All counterparties that Credit Suisse is exposed to are assigned an internal credit rating. The rating is assigned at the time of initial credit approval and subsequently reviewed and updated on an ongoing basis. Rating determination is based on relevant quantitative data (such as financial statements and financial projections) and qualitative factors relating to the counterparty which is used by CRM by employing a quantitative model which incorporates expert judgement through a well governed model override process in the assignment of a credit rating or PD, which measures the counterparty’s risk of default over a one-year period.
Counterparty and transaction rating process – Corporates (excluding corporates managed on the Swiss platform), banks and sovereigns (primarily in the Investment Banking division)
Where rating models are used, the models are an integral part of the rating process, and the outputs from the models are complemented with other relevant information by credit officers via a robust model-override framework where information not captured by the models is taken into account by experienced credit officers. In addition to the information captured by the rating models, credit officers make use of peer analysis, industry comparisons, external ratings and research and the judgment of credit experts to complement the model ratings. This analysis emphasizes a forward looking approach, concentrating on economic trends and financial fundamentals. Where rating models are not used the assignment of credit ratings is based on a well-established expert judgment based process which captures key factors specific to the type of counterparty.
For structured and asset finance deals, the approach is more quantitative. The focus is on the performance of the underlying assets, which represent the collateral of the deal. The ultimate rating is dependent upon the expected performance of the underlying assets and the level of credit enhancement of the specific transaction. Additionally, a review of the originator and/or servicer is performed. External ratings and research (rating agency and/or fixed income and equity), where available, are incorporated into the rating justification, as is any available market information (e.g., bond spreads, equity performance).
Transaction ratings are based on the analysis and evaluation of both quantitative and qualitative factors. The specific factors analyzed include seniority, industry and collateral. The analysis emphasizes a forward looking approach.
Counterparty and transaction rating process – Corporates managed on the Swiss platform, mortgages and other retail (primarily in the Private Banking & Wealth Management division)
For corporates managed on the Swiss platform and mortgage lending, the PD is calculated directly by proprietary statistical rating models, which are based on internally compiled data comprising both quantitative factors (primarily loan-to-value ratio and the borrower’s income level for mortgage lending and balance sheet information for corporates) and qualitative factors (e.g., credit histories from credit reporting bureaus). In this case, an equivalent rating is assigned for reporting purposes, based on the PD band associated with each rating. Collateral loans (margin lending), which form the largest part of “Other retail”, is also following an individual PD and LGD approach for loans managed on the Swiss platform, while a pool PD and pool LGD approach is followed elsewhere. Both approaches are calibrated to historical loss experience. Most of the collateral loans are loans collateralized by securities.

Transactions rated C are potential problem loans; those rated D1 are non-performing assets and those rated D2 are non-interest earning.
Use of internal ratings
Internal ratings play an essential role in the decision-making and the credit approval processes. The portfolio credit quality is set in terms of the proportion of investment and non-investment grade exposures. Investment/non-investment grade is determined by the internal rating assigned to a counterparty.
Internal counterparty ratings (and associated PDs), transaction ratings (and associated LGDs) and CCF for loan commitments are inputs to risk-weighted assets and Economic Risk Capital (ERC) calculations. Model outputs are the basis for risk-adjusted-pricing or assignment of credit competency levels.
The internal ratings are also integrated into the risk management reporting infrastructure and are reviewed in senior risk management committees. These committees include the Chief Executive Officer, Chief Credit Officer (CCO), Regional CCO, RPSC and Capital Allocation Risk Management Committee (CARMC).
Credit Risk Review
In 2015, Credit Suisse established an independent function Credit Risk Review (CRR) which performs cycled and continuous credit portfolio monitoring to ensure additional oversight of credit risk management, including ratings, credit analysis and credit administration. The CRR team received its mandate from the Group Board of Directors’ Risk Committee and its responsibilities include reviewing:
accuracy and consistency of assigned counterparty/transaction ratings;
transparency of rating justifications (both the counterparty rating and transaction rating);
quality of the underlying credit analysis and credit process;
adherence to Credit Suisse policies, guidelines, procedures, and documentation checklists;
compliance with regulatory requirements with respect to credit analysis and rating integrity.

Portfolios subject to the standardized and supervisory risk weights approaches
Standardized approach
Under the standardized approach, risk weights are determined either according to credit ratings provided by recognized external credit assessment institutions or, for unrated exposures, by using the applicable regulatory risk weights. Less than 10% of our credit risk is determined using this approach. Balances include banking book treasury liquidity positions.
Supervisory risk weights approach
For specialized lending exposures, internal rating grades are mapped to one of five supervisory categories, associated with a specific risk weight under the SRW approach.
Equity IRB Simple approach
For equity type securities in the banking book, risk weights are determined using the IRB Simple approach, which differentiates by equity sub-asset types (listed equity and all other equity positions). From January 1, 2014, the risk weighting for private equity positions was increased to 400%, in line with the treatment applied to other equity positions.

Credit risk mitigation used for A-IRB and standardized approaches
Credit risk mitigation processes used under the A-IRB and standardized approaches include on- and off-balance sheet netting and utilizing eligible collateral as defined under the IRB approach.
Netting
> Refer to “Derivative instruments” (pages 156 to 158) in III – Treasury, Risk, Balance sheet and Off-balance sheet – Risk management – Credit risk and to “Note 1 – Summary of significant accounting policies” (pages 241 to 242) in V – Consolidated financial statements – Credit Suisse Group in the Credit Suisse Annual Report 2014 for information on policies and procedures for on- and off-balance sheet netting.
> Refer to “Note 20 – Offsetting of financial assets and financial liabilities” (pages 115 to 118) in III – Condensed consolidated financial statements – unaudited in the Credit Suisse 2Q15 Financial Report for further information on the offsetting of derivatives, reverse repurchase and repurchase agreements, and securities lending and borrowing transactions.
Collateral valuation and management
The policies and processes for collateral valuation and management are driven by:
a legal document framework that is bilaterally agreed with our clients; and
a collateral management risk framework enforcing transparency through self-assessment and management reporting.
For collateralized portfolio by marketable securities, the valuation is performed daily. Exceptions are governed by the calculation frequency described in the legal documentation. The mark-to-market prices used for valuing collateral are a combination of firm and market prices sourced from trading platforms and service providers, where appropriate. The management of collateral is standardized and centralized to ensure complete coverage of traded products.
For the Private Banking & Wealth Management mortgage lending portfolio, real estate property is valued at the time of credit approval and periodically afterwards, according to our internal policies and controls, depending on the type of loan (e.g., residential, commercial) and loan-to-value ratio.
Primary types of collateral
The primary types of collateral are described below.
Collateral securing foreign exchange transactions and OTC trading activities primarily includes:
Cash and US Treasury instruments; and
G-10 government securities.
Collateral securing loan transactions primarily includes:
Financial collateral pledged against loans collateralized by securities of Private Banking & Wealth Management clients (primarily cash and marketable securities);
Real estate property for mortgages, mainly residential, but also multi-family buildings, offices and commercial properties; and
Other types of lending collateral, such as accounts receivable, inventory, plant and equipment.

Concentrations within risk mitigation
Our Investment Banking division is an active participant in the credit derivatives market and trades with a variety of market participants, principally commercial banks and broker dealers. Credit derivatives are primarily used to mitigate investment grade counterparty exposures.
Concentrations in our Private Banking & Wealth Management lending portfolio arise due to a significant volume of mortgages in Switzerland. The financial collateral used to secure loans collateralized by securities worldwide is generally diversified and the portfolio is regularly analyzed to identify any underlying concentrations, which may result in lower loan-to-value ratios.

Counterparty credit risk
Counterparty exposure
Counterparty credit risk arises from OTC and exchange-traded derivatives, repurchase agreements, securities lending and borrowing and other similar products and activities. The subsequent credit risk exposures depend on the value of underlying market factors (e.g., interest rates and foreign exchange rates), which can be volatile and uncertain in nature.
We have received approval from FINMA to use the internal model method for measuring counterparty risk for the majority of our derivative and secured financing exposures.
Credit limits
All credit exposure is approved, either by approval of an individual transaction/facility (e.g., lending facilities), or under a system of credit limits (e.g., OTC derivatives). Credit exposure is monitored daily to ensure it does not exceed the approved credit limit. These credit limits are set either on a potential exposure basis or on a notional exposure basis. Potential exposure means the possible future value that would be lost upon default of the counterparty on a particular future date, and is taken as a high percentile of a distribution of possible exposures computed by our internal exposure models. Secondary debt inventory positions are subject to separate limits that are set at the issuer level.
> Refer to “Credit risk” (pages 152 to 160) in III – Treasury, Risk, Balance sheet and Off-balance sheet – Risk management in the Credit Suisse Annual Report 2014 for further information on counterparty credit risk, including transaction rating, credit approval process and provisioning.
Wrong-way exposures
Correlation risk arises when we enter into a financial transaction where market rates are correlated to the financial health of the counterparty. In a wrong-way trading situation, our exposure to the counterparty increases while the counterparty’s financial health and its ability to pay on the transaction diminishes.
Capturing wrong-way risk requires the establishment of basic assumptions regarding correlations for a given trading product. We have multiple processes that allow us to capture and estimate wrong-way risk.
26

Credit approval and reviews
A primary responsibility of CRM is to monitor counterparty exposure and the creditworthiness of a counterparty, both at the initiation of the relationship and on an ongoing basis. Part of the review and approval process is an analysis and discussion to understand the motivation of the client and to identify the directional nature of the trading in which the client is engaged. Credit limits are agreed in line with the Group’s risk appetite framework taking into account the strategy of the counterparty, the level of disclosure of financial information and the amount of risk mitigation that is present in the trading relationship (e.g., level of collateral).
Exposure adjusted risk calculation
Material trades that feature specific wrong-way risk are applied a conservative treatment for the purpose of calculating exposure profiles. The wrong-way risk framework applies to OTC, securities financing transactions and centrally cleared trades.
Wrong-way risk arises if the exposure the Group has against a counterparty is expected to be high when the probability of default of that counterparty is also high. Wrong-way risk can affect the exposure against a counterparty in two ways:
The mark-to-market of a trade can be large if the counterparty’s PD is high.
The value of collateral pledged by that counterparty can be low if the counterparty’s PD is high.
Two main types of wrong-way risk are distinguished:
“General wrong-way risk” arises when the likelihood of default by counterparties is positively correlated with general market risk factors.
“Specific wrong-way risk” arises when potential exposure to a specific counterparty is positively correlated with the counterparty’ probability of default due to the nature of the transactions with the counterparty.
There are two variants of specific wrong-way risk:
If there is a legal connection between the counterparty and the exposure, e.g. the Group buying a put from a counterparty on shares of that counterparty or a parent/subsidiary of that counterparty or a counterparty pledging its own shares or bonds as collateral.
More general correlation driven specific wrong-way risk.
The presence of wrong-way risk is detected via automated checks for legal connection and via means of stress scenarios and historical time series analyses for correlation.
For those instances where a material wrong-way risk presence is detected, limit utilization and default capital are accordingly adjusted.
Regular reporting of wrong-way risk at both the individual trade and portfolio level allows wrong-way risk to be identified and corrective action taken in the case of heightened concern by CRM. Reporting occurs at various levels:
Country exposure reporting – Exposure is reported against country limits established for emerging market countries. Exposures that exhibit wrong-way characteristics are given higher risk weighting versus non-correlated transactions, resulting in a greater amount of country limit usage for these trades.
Counterparty exposure reporting – Transactions that contain wrong-way risk are risk-weighted as part of the daily exposure calculation process, as defined in the credit analytics exposure methodology document. This ensures that correlated transactions utilize more credit limit.
Correlated repurchase and foreign exchange reports – Monthly reports produced by CRM capturing correlated repurchase and foreign exchange transactions. This information is reviewed by relevant CRM credit officers.
Scenario risk reporting – In order to identify areas of potential wrong-way risk within the portfolio, a set of defined scenarios are run monthly by Risk Analytics and Reporting. The scenarios are determined by CRM and involve combining existing scenario drivers with specific industries to determine where portfolios are sensitive to these stressed parameters, e.g. construction companies / rising interest rates.
Scenario analysis is also produced for hedge funds which are exposed to particular risk sensitivities and also may have collateral concentrations due to a specific direction and strategy.
In addition, and where required, CRM may prepare periodic trade level scenario analysis, in order to review the risk drivers and directionality of the exposure to a counterparty.
The Front Office is responsible for identifying and escalating trades that could potentially give rise to wrong-way risk.
Any material wrong-way risk at portfolio or trade level should be escalated to senior CRM executives and risk committees.
Effect of a credit rating downgrade
On a daily basis, we monitor the level of incremental collateral that would be required by derivative counterparties in the event of a Credit Suisse ratings downgrade. Collateral triggers are maintained by our collateral management department and vary by counterparty.
> Refer to “Credit ratings” (page 51) in II – Treasury, risk, balance sheet and off-balance sheet – Liquidity and funding management in the Credit Suisse 2Q15 Financial Report for further information on the effect of a one, two or three notch downgrade as of June 30, 2015.
The impact of downgrades in the Bank’s long-term debt ratings are considered in the stress assumptions used to determine the conservative funding profile of our balance sheet and would not be material to our liquidity and funding needs.

Credit exposures on derivative instruments
We enter into derivative contracts in the normal course of business for market making, positioning and arbitrage purposes, as well as for our own risk management needs, including mitigation of interest rate, foreign currency and credit risk. Derivative exposure also includes economic hedges, where the Group enters into derivative contracts for its own risk management purposes but where the contracts do not qualify for hedge accounting under US GAAP. Derivative exposures are calculated according to regulatory methods, using either the current exposures method or approved internal models method. These regulatory methods take into account potential future movements and as a result generate risk exposures that are greater than the net replacement values disclosed for US GAAP.
As of the end of 6M15, no credit derivatives were utilized that qualify for hedge accounting under US GAAP.

Securitization risk in the banking book
The following disclosures, which also considers the “Industry good practice guidelines on Pillar 3 disclosure requirements for securitization”, refer to traditional and synthetic securitizations held in the banking book and regulatory capital on these exposures calculated according to the Basel III IRB and standardized approaches to securitization exposures.
> Refer to “Note 33 – Transfers of financial assets and variable interest entities” (pages 314 to 322) in V – Consolidated financial statements – Credit Suisse Group in the Credit Suisse Annual Report 2014 and “Note 26 – Transfers of financial assets and variable interest entities” (pages 132 to 138) in III – Condensed consolidated financial statements – unaudited in the Credit Suisse 2Q15 Financial Report for further information on securitization, the various roles, the use of SPEs, the involvement of the Group in consolidated and non-consolidated SPEs, the accounting policies for securitization activities and methods and key assumptions applied in valuing positions retained/purchased.
A traditional securitization is a structure where an underlying pool of assets is sold to an SPE which pays for the assets by issuing tranched securities collateralized by the underlying asset pool. A synthetic securitization is a tranched structure where the credit risk of an underlying pool of assets is transferred, in whole or in part, through the use of credit derivatives or guarantees that may serve to hedge the credit risk of the portfolio. Many synthetic securitizations are not accounted for as securitizations under US GAAP. In both traditional and synthetic securitizations, risk is dependent on the seniority of the retained interest and the performance of the underlying asset pool.
The Group has both securitization and re-securitization transactions in the banking book referencing different types of underlying assets including real estate loans (commercial and residential), commercial loans and credit card loans. The key risks retained are related to the performance of the underlying assets. These risks are summarized in the securitization pool level attributes: PDs of underlying loans (default rate), severity of loss (LGD) and prepayment speeds. The transactions may also be exposed to general market risk, credit spread and counterparty credit risk.
The Group classifies securities within the transactions by the nature of the collateral (prime, sub-prime, Alt-A, commercial, etc.) and the seniority each security has in the capital structure (i.e. senior, mezzanine, subordinate etc.), which in turn will be reflected in the transaction rating. The Group’s internal risk methodology is designed such that risk charges are based on the place the particular security holds in the capital structure, the less senior the bond the higher the risk charges.
For re-securitization risk, the Group’s risk management models take a ‘look through’ approach where the behavior of the underlying securities or constituent counterparties are modeled based on their own particular collateral positions. These are then transmitted to the re-securitized position. No additional risk factors are considered within the re-securitization portfolios in addition to those identified and measured within securitization risk.
The Group is active in various roles in connection with securitization, including originator, investor and sponsor. As originator, the Group creates or purchases financial assets (e.g., residential mortgages or corporate loans) and then securitizes them in a traditional or synthetic transaction that achieves significant risk transfer to third party investors. The Group acts as liquidity provider to Alpine Securitization Corp. (Alpine), a multi-seller commercial paper conduit administered by Credit Suisse.
In addition, the Group invests in securitization-related products created by third parties and provides interest rate and currency swaps to SPEs involved in securitization activity.
Retained banking book exposures for mortgage, asset-backed securities (ABS) and collateralized debt obligation (CDO) transactions are risk managed on the same basis as similar trading book transactions. Other transactions will be managed in line with their individual structural or parameter requirements. The Group has also put in place a set of key risk limits for the purpose of managing the Group’s risk appetite framework in relation to securitizations and re-securitizations. The internal risk capital measurement is both consistent with securitization transactions and with similar structures in the trading book.
There are no instances where the Group has applied credit risk mitigation approaches to banking book securitization or re-securitization exposures.
In the normal course of business it is possible for the Group’s managed separate account portfolios and the Group’s controlled investment entities, such as mutual funds, fund of funds, private equity funds and other fund linked products to invest in the securities issued by other vehicles sponsored by the Group engaged in securitization and re-securitization activities. To address potential conflicts, standards governing investments in affiliated products and funds have been adopted.

Equity type securities in the banking book
Overview
The classification of our equity type securities into trading book and banking book is made for regulatory reporting purposes. The banking book includes all items that are not classified in the trading book.
Most of our equity type securities in the banking book are classified as investment securities whereas the remaining part is classified as trading assets.
For equity type securities in the banking book except for significant investments in BFI entities that are subject to a threshold treatment as outlined in “Exposures below 15% threshold” in section “Capital” on page 8, risk weights are determined using the IRB Simple approach based on the equity sub-asset type. Where equity type securities represent non-significant investments in BFI entities, a threshold approach is applied, that compares the total amount of non-significant investments in BFI entities (considering both trading and banking book positions) to a 10% regulatory defined eligible capital amount. The amount above the threshold is phased-in as a capital deduction and the amount below the threshold continues to be risk-weighted according to the relevant trading book and banking book approaches.
The numbers in the following table “Equity type securities in the banking book” present the balance sheet value of banking book equity investments and the regulatory exposures to which capital is applied according to the IRB Simple approach. The main differences are the scope of consolidation (primarily deconsolidation of private equity and other fund type vehicles for capital adequacy purposes), significant investments in BFI entities and regulatory approaches such as the net-long calculation and the look-through approach on certain equity securities.
Risk measurement and management
Our banking book equity portfolio includes positions in hedge funds, private equity and other instruments that may not be strongly correlated with general equity markets. Equity risk on banking book positions is measured using sensitivity analysis that estimates the potential change in value resulting from a 10% decline in the equity markets of developed nations and a 20% decline in the equity markets of emerging market nations.

Central counterparties risk
The Group can incur exposure to CCPs as either a clearing member (house or client trades), or clearing through another member. Qualifying CCPs are expected to be subject to best-practice risk management, and sound regulation and oversight to ensure that they reduce risk, both for their participants and for the financial system. Most CCPs are benchmarked against standards issued by the Committee on Payment and Settlement Systems and the Technical Committee of the International Organization of Securities Commissions, herein collectively referred to as “CPSS-IOSCO”.
The existing credit review process includes annual review of qualitative and quantitative factors for all counterparty types, including CCPs. As part of the credit review of each CCP counterparty, CRM conducts due diligence and based on assessment by the Legal and Compliance Department determines whether (i) the CCP is a qualifying CCP and (ii) the collateral posted is considered bankruptcy remote.
The CRM CCP Guidelines provide detailed guidance on how these flags should be assigned against the standards issued by “CPSS-IOSCO”. These include a review of collateral bankruptcy remoteness and that the CCPs holds securities in custody with entities that employ safekeeping procedures and internal controls that fully protect these securities. The review will include analysis of the CCPs policies with respect to account segregation and use of custodians. The determination is made in the context of “Authorization of CCP” (European Market Infrastructure Regulation (EMIR), Article 10) and “Third Countries” (EMIR, Article 23). This information will be appropriately reflected in the risk weightings within the capital calculations.
The Group monitors its daily exposure to the CCP as part of its ongoing limit and exposure monitoring process.

Market risk
General
Market risk is managed under the IMA approach and under the approved securitization methodologies. Validation of the IMA models is performed by the Model Risk Management team, an independent function, and is subject to clear and objective internal standards as outlined in the Validation Policy.
The following table shows risk-weighted assets for all market risk measures including the standardized approach.

Roles in connection with trading book securitization
Within its mortgage business there are four key roles that the Group undertakes within securitization markets: issuer, underwriter, market maker and financing counterparty. The Group holds one of the top trading franchises in market making in all major securitized product types and is a top issuer and underwriter in the re-securitization market in the US as well as being one of the top underwriters in ABS securitization in the US. In addition the Group also has a relatively small correlation trading portfolio.
Securitization and re-securitization activities
The Group’s key objective in relation to trading book securitization is to meet clients’ investment and divestment needs by making markets in securitized products across all major collateral types, including residential mortgages, commercial mortgages, asset finance (i.e. auto loans, credit card receivables, etc.) and corporate loans. The Group focuses on opportunities to intermediate transfers of risk between sellers and buyers.
The Group is also active in new issue securitization and re-securitization. The Group’s Asset Finance team provides short-term secured warehouse financing to clients who originate credit card, auto loan, and other receivables, and the Group sells asset-backed securities collateralized by these receivables to provide its clients long-term financing that matches the lives of their assets.
The Group purchases loans and bonds for the purpose of securitization and sells these assets to sponsored SPEs which in turn issue new securities. Re-securitizations of previously issued residential mortgage-backed securities (RMBS) securities occur when 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 repackage an existing security to give the investor a higher rated tranche.
Risks assumed and retained
Key risks retained while securities or loans remain in inventory are related to the performance of the underlying assets (real estate loans, commercial loans, credit card loans, etc.). These risks are summarized in the securitization pool level attributes: PD of underlying loans (default rate), the severity of loss and prepayment speeds. The Group maintains models for both government-guaranteed and private label mortgage products. These models project the above risk drivers based on market interest rates and volatility as well as macro-economic variables such as housing price index, projected GDP and inflation, unemployment etc.
In its role as a market maker, the Group actively trades in and out of positions. Both Front Office and Risk Management continuously monitor liquidity risk as reflected in trading spreads and trading volumes. To address liquidity concerns a specific set of limits on the size of aged positions are in place for the securitized positions we hold.
The Group classifies securities by the nature of the collateral (prime, sub-prime, Alt-A, commercial, etc.) and the seniority each security has in the capital structure (i.e. seniors, mezzanine, subordinate etc.), which in turn will be reflected in the transaction risk assessment. Risk Management monitors portfolio composition by capital structure and collateral type on a daily basis with subordinate exposure and each collateral type subject to separate risk limits. In addition, the internal risk methodology is designed such that risk charges are based on the place the particular security holds in the capital structure, the less senior the bond the higher the risk charges.
For re-securitization risk, the Group’s risk management models take a ‘look through’ approach where they model the behavior of the underlying securities based on their own collateral and then transmit that to the re-securitized position. No additional risk factors are considered within the re-securitization portfolios in addition to those identified and measured within securitization risk.
With respect to both the wind-down corporate correlation trading portfolio and the on-going transactions the key risks that need to be managed includes default risk, counterparty credit risk, correlation risk and cross effects between spread and correlation.
Both correlation and first-to-default are valued using a correlation model which uses the market implied correlation and detailed market data such as constituent spread term structure and constituent recovery. The risks embedded in securitization and re-securitizations are similar and include spread risk, recovery risk, default risk and correlation risk. The risks for different seniority of tranches will be reflected in the tranche price sensitivities to each constituent in the pools.
Monitoring of changes in credit and market risk of securitization exposures
The Group has in place a comprehensive risk management process whereby the front office and Risk Management work together to monitor positions and position changes, portfolio structure and trading activity and calculate a set of risk measures on a daily basis using risk sensitivities and loss modeling methodologies.
For the mortgage business the Group also uses monthly remittance reports (available from public sources) to get up to date information on collateral performance (delinquencies, defaults, pre-payment etc.).
The Group has also put in place a set of limits for the purpose of managing the Group’s risk appetite framework in relation to securitizations and re-securitizations. These limits will cover exposure measures, risk sensitivities, VaR and capital measures with the majority monitored on a daily basis. In addition within the
37

Group’s risk management framework an extensive scenario analysis framework is in place whereby all underlying risk factors are stressed to determine portfolio sensitivity.
Re-securitized products in the mortgage business go through the same risk management process but looking through the structures with the focus on the risk of the underlying securities or constituent names.
Risk mitigation
In addition to the strict exposure limits noted above, the Group uses a number of different risk mitigation approaches to manage risk appetite for its securitization and re-securitization exposures. Where true counterparty credit risk exposure is identified for a particular transaction, there is a requirement for it to be approved through normal credit risk management processes with collateral taken as required. The Group also may use various proxies including corporate single name and index hedges to mitigate the price and spread risks to which it is exposed. Hedging decisions are made by the trading desk based on current market conditions and will be made in consultation with Risk Management. Every trade has a trading mandate where unusual and material trades require approval under the Group’s pre-trade approval governance process. International investment banks are the main counterparties to the hedges that are used across these business areas.
In the normal course of business, we may hold tranches which have a monoline guarantee. No benefit from these guarantees is currently included in the calculation of regulatory capital.
Affiliated entities
Funds affiliated with the Group may invest in securities issued by other vehicles sponsored by the Group that are engaged in securitization and re-securitization activities. These funds include mutual funds, fund of funds and private equity funds. Standards governing investments in affiliated funds and products have been adopted to address potential conflicts.

Other information
As of June 30, 2015, the Group holds the following positions with the intent to securitize: government-guaranteed commercial loans of USD 2.5 billion, government-guaranteed residential pass-through securities of USD 3.4 billion, residential whole loans of USD 1.1 billion and commercial whole loans of USD 3.7 billion. The actual securitizations are subject to future market conditions. There is no difference in the valuation of positions intended to be securitized.
Valuation process
The Basel capital adequacy framework and FINMA circular 2008/20 provide guidance for systems and controls, valuation methodologies and valuation adjustments and reserves to provide prudent and reliable valuation estimates.
Financial instruments in the trading book are carried at fair value. The fair value of the majority of these financial instruments is marked to market based on quoted prices in active markets or observable inputs. Additionally, the Group holds financial instruments which are marked to models where the determination of fair values requires subjective assessment and varying degrees of judgment depending on liquidity, concentration, pricing assumptions and the risks affecting the specific instrument.
Control processes are applied to ensure that the reported fair values of the financial instruments, including those derived from pricing models, are appropriate and determined on a reasonable basis. These control processes include approval of new instruments, timely review of profit and loss, risk monitoring, price verification procedures and validation of models used to estimate the fair value. These functions are managed by senior management and personnel with relevant expertise, independent of the trading and investment functions.
In particular, the price verification function is performed by Product Control, independent from the trading and investment functions, reporting directly to the Chief Financial Officer, a member of the Executive Board.
The valuation process is governed by separate policies and procedures. To arrive at fair values, the following type of valuation adjustments are typically considered and regularly assessed for appropriateness: model, parameter, credit and exit-risk-related adjustments.
Management believes it complies with the relevant valuation guidance and that the estimates and assumptions used in valuation of financial instruments are prudent, reasonable and consistently applied.

Interest rate risk in the banking book
Overview
Credit Suisse monitors and manages interest rate risk in the banking book by established systems, processes and controls. Risk sensitivity figures are provided to estimate the impact of changes in interest rates, which is one of the primary ways in which these risks are assessed for risk management purposes. In addition, Risk Division confirms that the economic impacts of adverse parallel shifts in interest rates of 200 basis points and adverse interest rate shifts calibrated to a 1-year holding period with a 99% confidence level are significantly below the threshold of 20% of eligible regulatory capital used by the regulator to identify banks that potentially run excessive levels of non-trading interest rate risk. Given the low level of interest rate risk in the banking book, Credit Suisse does not have any regulatory requirement to hold capital against this risk.
Major sources of interest rate risk in the banking book
The interest rate risk exposures in the non-trading positions (synonymously used to the term “banking book”) mainly arise from the retail banking activities of the Private Banking & Wealth Management division, the positioning strategy with respect to our replicated non-interest bearing assets and liabilities (including the equity balance) and the outstanding capital instruments. The vast majority of interest rate risk in the banking book is managed by Treasury and Private Banking & Wealth Management on a portfolio basis.
The interest rate risk from retail banking activities results from the transactions with repricing maturities that either are or are not contractually determined. In the former case since 2014 positions are managed within Private Banking & Wealth Management. For most parts of the latter, such as variable rate mortgages and some types of deposits, which do not have a direct link to market rates in their repricing behavior, it is more suitable to manage them on a portfolio basis rather than on individual trade level. The interest rate risk associated with these products, referred to as non-maturing products, is estimated using the methodology of replicating portfolios: Based on the historical behavior of interest rates and volume of these products it assigns the position balance associated with a non-maturing banking product to time bands that are presumed to reflect their empirical repricing maturities. The methodology is based, where reasonably possible, on the principle of finding a stable relationship between the changes of client rates of the non-maturing products and an underlying investment or funding portfolio. Where this is not possible, the maturity of the product is assessed based on volume stability only. These allocations to time bands can then be used to evaluate the products’ interest rate sensitivity. The structure and parameters of the replicating portfolios are reviewed periodically to ensure continued relevance of the portfolios in light of changing market conditions and client behavior.
For managing parts of the interest rate risk of the corporate balance sheet with respect to our non-interest bearing assets and liabilities (including the equity balance) Credit Suisse assigns tenors to balance sheet positions that reflect a fair investment or funding profile for the underlying balance sheet items. This strategy is implemented by Treasury and the resulting interest rate risk is measured against a pre-defined benchmark.
Changing market rates give rise to changes in the fair values of the outstanding capital instruments that have been issued for funding of the bank. To some extent, on an individual basis, this risk is being mitigated by using swaps to replace fixed payment obligations into floating ones. In addition to these transactions on individual basis, the residual interest rate risk is also managed holistically by Treasury.
Governance of models and limits
The major part of interest rate risk in the banking book is managed centrally by Treasury and Private Banking & Wealth Management within approved limits using hedging instruments such as interest rate swaps. The Board of Directors defines the risk appetite, i.e. a set of risk limits, for the Group on an annual basis. Limits to the divisions are governed by the CARMC; the divisional Risk Management Committees may assign limits on more granular levels for entities, businesses, books, collections of books. The models used for measuring risk are reviewed and validated by the RPSC, where the frequency depends on the criticality of the model. Operational decisions on the use of the models (e.g. in terms of maximum tenor and allocation of tranches to the time bands in the replicating portfolios) is governed by the CARMC. For interest rate risk in the banking book, Risk Division is responsible for monitoring the limit usage and escalating potential limit breaches.
Risk measurement
The risks associated with the non-trading interest rate-sensitive portfolios are measured using a range of tools, including the following key metrics:
Interest rate sensitivity (DV01): Expresses the linear approximation of the impact on a portfolio’s fair value resulting from a one basis point (0.01%) parallel shift in yield curves, where the approximation tends to be closer to the true change in the portfolio’s fair value for smaller parallel shifts in the yield curve. The DV01 is a transparent and intuitive indicator of linear directional interest rate risk exposure, which does not rely on statistical inference.
VaR: Statistical indicator of the potential fair value loss, taking into account the observed interest rate moves across yield curve tenors and currencies. In addition, VaR takes into account yield curve risk, spread and basis risks, as well as foreign exchange and equity risk. For risk management purposes, Credit Suisse uses a VaR measure based on a one-day holding period with a 98% confidence level where the considered
43

historical values are time-weighted using a weighting scheme that assigns lower weights to observations further in the past.
ERC: ERC is a statistical risk indicator representing the capital the bank should hold to support the risks incurred. ERC is calibrated to a 1-year holding period with a 99% confidence level for risk management purposes.
Economic value scenario analysis: Expresses the impact of a pre-defined scenario (e.g. instantaneous changes in interest rates) on a portfolio’s fair value. This metric does not rely on statistical inference.
The measures listed above focus on the impact on a fair value basis, taking into account the present value of all future cash flows associated with the current positions. More specifically, the metrics estimate the impact on the economic value of the current portfolio, ignoring dynamic aspects such as the time schedule of how changes in economic value materialize in P&L (since most non-trading books are not marked-to-market) and the development of the portfolio over time. These measures are complemented by considering an Earnings-at-Risk approach to interest rate risk: For the major part of the banking books, this is accomplished by simulating the development of the net interest income over several years using scenarios of potential changes of the yield curves. This scenario analysis also takes into account the earnings impact originating from fluctuations in short term interest rates, which are regarded as riskless when analyzing the impact on economic value. In addition to the dynamic aspects, this analysis allows to distinguish between the economic and the accounting view.
Monitoring and review
The limits and flags defined by books, collections of books, businesses or legal entities relating to interest rate risk in the banking book are monitored by Risk Division at least on a monthly basis (if deemed necessary or suitable, the monitoring may be as frequent as daily), by using the metrics and methodologies outlined above. In case of breaches, this is escalated to the limit-setting body. Credit Suisse assesses compliance with regulatory requirements regarding appropriate levels of non-trading interest rate risk by estimating the economic impact of adverse 200 basis point parallel shifts in yield curves and adverse interest rate shifts calibrated to a 1-year holding period with a 99% confidence level and then relating those impacts to the total eligible regulatory capital. Consistent with regulatory requirements, Risk Division ensures that the fair value impact of this analysis is below the threshold of 20% of eligible regulatory capital in which case there are no requirements to hold additional capital. This analysis is performed for the Group and major legal entities, including the Bank, on a monthly basis.
Risk profile
The following table shows the impact of a one basis point parallel increase of the yield curves on the fair value of interest rate-sensitive banking book positions as of the end of 6M15 and 2014.
One-basis-point parallel increase in yield curves by currency - banking book positions
end of CHF USD EUR GBP Other Total
6M15 (CHF million)   
Fair value impact of a one-basis-point parallel increase in yield curves (1.6) 3.5 0.9 0.0 0.6 3.4
2014 (CHF million)   
Fair value impact of a one-basis-point parallel increase in yield curves (2.4) 4.6 1.9 (0.1) 0.6 4.6
This risk is monitored on a daily basis. The monthly analysis of the potential impact resulting from a significant change in yield curves indicates that as of the end of 6M15 and 2014, the fair value impact of an adverse 200 basis point move in yield curves and adverse interest rate moves calibrated to a 1-year holding period with a 99% confidence level, both in relation to the total eligible regulatory capital, were significantly below the 20% threshold. This is used by regulators to identify banks that potentially run excessive levels of non-trading interest rate risk. This was true for the Group and all legal entities covered in the assessment process, including the Bank.
