1. Introduction

The purpose of this Pillar 3 report is to provide updated information as of June 30, 2009 on our implementation of the Basel II 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 2008 and the 2Q09 Financial Report, which include important information on regulatory capital and risk management (specific references have been made herein to those documents). Since January 1, 2008, Credit Suisse has operated under the international capital adequacy standards set forth by the Basel Committee on Banking Supervision, known as Basel II, as implemented by FINMA (Swiss Financial Market Supervisory Authority).

In certain cases, the Pillar 3 disclosures differ from the way we manage our risks for internal management purposes and disclose them in the Annual Report. For further information regarding the way that we manage risk, refer to III – Treasury, Risk, Balance sheet and Off-balance sheet – Risk management (pages 112 to 133) in the Credit Suisse Annual Report 2008.

As foreseen under the Basel II framework, this report excludes analysis of changes in disclosure balances since December 31, 2008, however analysis of such year-on-year movements will be included in our Pillar 3 report as of December 31, 2009.

Certain reclassifications have been made to prior periods to conform to the current period’s presentation.

Scope of application

The highest consolidated entity in the Group to which Basel II applies is Credit Suisse Group. For further information on regulation, refer to I – Information on the company – Regulation and supervision (pages 35 to 38) and to III – Treasury, Risk, Balance sheet and Off-balance sheet (pages 96 to 133) in the Credit Suisse Annual Report 2008.

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). These investments, 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. FINMA has advised the Group that it may continue to include equity from special purpose entities that are deconsolidated under FIN 46(R) as tier 1 capital. We have also received an exemption from FINMA not to consolidate private equity fund type vehicles.

For a list of significant subsidiaries and associated entities of Credit Suisse, refer to Note 38 – Significant subsidiaries and equity method investments in V – Consolidated financial statements – Credit Suisse Group (pages 275 to 277) in the Credit Suisse Annual Report 2008.

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.

For information on our liquidity, funding and capital management and dividends and dividend policy, refer to III – Treasury, Risk, Balance sheet and Off-Balance sheet – Treasury management (pages 96 to 115) in the Credit Suisse Annual Report 2008.

2. Capital

For information on our capital structure, eligible capital and shareholders’ equity and capital adequacy refer to III – Treasury, Risk, Balance sheet and Off-Balance sheet – Treasury management (pages 100 to 106) in the Credit Suisse Annual Report 2008 and IV – Treasury and Risk management – Treasury management (pages 54 to 59) in the Credit Suisse 2Q09 Financial Report.

Regulatory capital is calculated and managed according to Basel II and used to determine BIS ratios and, according to the Swiss Capital Adequacy Ordinance, the FINMA capital requirement covering ratio. The main differences between the BIS and FINMA calculations are the multipliers used for certain risk classes and additional FINMA requirements for market risk. The main impact of the multipliers is related to non-counterparty-related risks, for which FINMA uses a multiplier of 3.0 versus 1.0 for BIS. The additional FINMA requirements for market risk are for Value-at-Risk (VaR) backtesting exceptions, where FINMA imposes higher multipliers than BIS for more than ten exceptions, and stress-test-based risk-weighted assets for hedge funds.

BIS ratios compare eligible capital by tier 1 and total capital with BIS risk-weighted assets whereas the FINMA capital requirement covering ratio compares total capital with FINMA required capital.

During the transition period from Basel I to Basel II, the capital requirements include a floor adjustment that limits the benefit received from conversion. For Credit Suisse Group, the floor adjustment only had an impact on the FINMA capital requirements.

Description of regulatory approaches

Basel II 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 that risk is internally managed and provide the greatest risk sensitivity. Basel II focuses on credit risk, market risk, operational risk, securitization risk and equity 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

Basel II permits banks a choice between two broad methodologies in calculating their capital requirements for credit risk, 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 is with institutional counterparties (sovereigns, other institutions, banks and corporates) and arises from lending and trading activity in the Investment Banking and Private Banking divisions. The remaining credit risk is with retail counterparties and mostly arises in the Private Banking division from residential mortgage loans and other secured lending, including loans collateralized by securities.

Under the IRB approach, risk weights are determined by using internal risk parameters. 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). We use the A-IRB approach to determine our institutional credit risk and most of our retail credit risk.

PD parameters capture the risk of a counterparty defaulting over a one-year time horizon. PD estimates are based on time-weighted averages of historical default rates by rating grade, with low-default-portfolio estimation techniques applied for higher quality rating grades. Each PD reflects the internal rating for the relevant obligor.

LGD parameters consider seniority, collateral and counterparty industry. 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 loan portfolio, the LGD is primarily dependent upon the type and amount of collateral pledged. For other retail credit risk, predominantly loans secured by financial collateral, pool LGDs differentiate between standard and higher risks, as well as domestic and foreign transactions. 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 gross 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.

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.

Market risk

For calculating the capital requirements for market risk, the internal models approach (IMA) or the standardized approach is used. 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 vast 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 and auditors.

We use the standardized approach to determine our market risk for a small number of positions, which represent an immaterial proportion of our overall market risk exposure.

Operational risk

We have received approval from FINMA to use the advanced measurement approach (AMA) for measuring operational risk. Under this approach we have identified key scenarios that describe major operational risks relevant to us, and the capital requirement is calculated using an event model.

Securitization risk

For securitizations, the regulatory capital requirements are calculated using IRB approaches: the ratings-based approach (RBA) and the supervisory formula approach (SFA).

Other risks

For equity type securities in the banking book, risk weights are determined using the IRB Simple approach based on the equity sub-asset type (qualifying private equity, listed equity and all other equity positions).

Fixed risk weights are applied to settlement and non-counterparty-related exposures.

For other items, we received approval from FINMA to apply a simplified Institute Specific Direct Risk Weight approach to immaterial portfolios.

3. Risk exposure and assessment

For information on risk governance, risk organization, risk types and risk limits, refer to III – Treasury, Risk, Balance sheet and Off-balance sheet – Risk management (pages 112 to 133) in the Credit Suisse Annual Report 2008.

4. Credit risk

General

For information on our credit risk management approach, ratings and risk mitigation and impaired exposures and allowances, refer to III – Treasury, Risk, Balance sheet and Off-balance sheet – Risk management (pages 120 to 133) in the Credit Suisse Annual Report 2008.

For regulatory purposes, we categorize our exposures into broad classes of assets with different underlying risk characteristics including type of counterparty, size of exposure and type of collateral. The asset class categorization is driven by Basel II regulatory rules. The credit asset classes under Basel II are set forth below and are grouped as either institutional or retail.

Institutional credit risk

– Sovereigns: exposures to central governments, central banks, BIS, the International Monetary Fund, the European Central Bank and eligible Multilateral Development Banks (MDB).

– Other institutions: exposures to public bodies with the right to raise taxes or whose liabilities are guaranteed by a public sector entity.

– Banks: exposures to banks, securities firms, stock exchanges and those MDB that do not qualify for sovereign treatment.

– 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).

Retail credit risk

– Residential mortgages: includes exposures secured by residential real estate collateral occupied or let by the borrower.

– Qualifying revolving retail: includes credit card receivables and overdrafts.

– Other retail: includes loans collateralized by securities and small business exposures.

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

Rating models are based on statistical data and are subject to a thorough review before implementation. Each credit rating model has been developed by Credit Risk Management (CRM) and has been independently validated by Risk Measurement and Management prior to use within the Basel II regulatory capital calculation, and thereafter on a regular basis. To ensure that ratings are consistent and comparable across all businesses, we have used an internal rating scale which is benchmarked to an external rating agency using the historical PD associated with external ratings.

New or materially changed rating models are submitted for approval to the Risk Processes and Standards Committee (RPSC) prior to implementation. RPSC reviews the continued use of existing models on an annual basis.

CRM is an independent function with responsibility for approving credit ratings and limits, monitoring and managing individual exposures and assessing and managing the quality of the segment and business area’s credit portfolios. CRM reports to the Chief Risk Officer.

Descriptions of the rating processes

For the purposes of internal ratings, we have developed a set of credit rating models tailored for different internal client segments in both Investment Banking and Private Banking (e.g., international corporates, financial institutions, asset finance, small and medium-sized entities, commodity traders, residential mortgages, etc.) and transaction types.

Counterparty and transaction rating process – international corporates, banks and sovereigns (primarily in the Investment Banking division)

Internal ratings are based on the analysis and evaluation of both quantitative and qualitative factors. The specific factors analyzed are dependent on the type of counterparty. The analysis emphasizes a forward looking approach, concentrating on economic trends and financial fundamentals. Analysts make use of peer analysis, industry comparisons, other quantitative tools and the judgment of credit experts.

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 – Swiss corporates, mortgages and other retail (primarily in the Private Banking division)

For Swiss corporates and mortgage lending, the statistically derived rating models, which are based on internal data history of quantitative and qualitative factors, are supplemented by the judgment of credit experts. For mortgages, information about the real estate property, including loan-to-value ratio, is also considered. Collateral loans, which form the largest part of “other retail”, are treated according to Basel II rules with pool PD and pool LGD based on historical loss experience. Most of the collateral loans are loans collateralized by securities.

As a rule, the allocation of exposures to institutional or retail as outlined in the following tables is based on the different rating models, but also takes into account further explicit regulatory rules.

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.

Supervisory risk weights approach

For specialized lending exposures, internal rating grades are mapped to one of five supervisory categories, each of which is 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 (qualifying private equity, listed equity and all 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

For information on policies and procedures for on- and off-balance sheet netting, refer to III – Treasury, Risk, Balance sheet and Off-balance sheet – Risk management (page 129) and to Note 1 – Summary of significant accounting policies in V – Consolidated financial statements – Credit Suisse Group (page 193) in the Credit Suisse Annual Report 2008.

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.

In substantially all cases, the valuation of the collateralized portfolio 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 mortgage lending portfolio, real estate property is valued at the time of credit approval and periodically afterwards, according to our internal directives 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;

– G-10 government securities; and

– Gold or other precious metals.

Collateral securing loan transactions primarily includes:

– Financial collateral pledged against loans collateralized by securities of Private Banking clients (mostly 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 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. For further information on risk mitigation, refer to III – Treasury, Risk, Balance sheet and Off-balance sheet – Risk management (pages 123 to 125) in the Credit Suisse Annual Report 2008.

Counterparty credit risk

Counterparty exposure

Counterparty exposure arises from OTC derivatives, repurchase agreements, securities lending and borrowing and other similar products and activities. These 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 derivative loan equivalent (DLE) exposure basis or on a notional exposure basis. DLE is a form of potential future exposure calculation allowing a fair comparison between loan and unsecured derivative exposures. Secondary debt inventory positions are subject to separate limits that are set at the issuer level.

For further information on counterparty credit risk, including counterparty and transaction rating, credit approval process and provisioning, refer to III – Treasury, Risk, Balance sheet and Off-balance sheet – Risk management (pages 120 to 132) in the Credit Suisse Annual Report 2008.

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 rules regarding correlations within a given trading product. We have multiple processes that allow us to capture and calculate wrong-way risk.

Credit approval and reviews

A primary responsibility of CRM is the approval of new counterparty trading relationships and the subsequent ongoing review of the creditworthiness of the client. 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 sized to the level of comfort the CRM officer has with 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

Trades that feature correlation risk have higher risk weighting built into the exposure calculation process compared to “right-way” trades.

– Purchased credit default swaps – Correlation exists where the counterparty and the underlying reference asset belong to the same group or where the seller of protection has a similar or lower credit rating than the reference asset and the same country of risk. In these cases, exposure is calculated assuming default and applying the recovery value of the underlying reference asset.

– Equity finance – Correlation exists if there is a high correlation between the counterparty and the underlying equity; in this case, exposure is calculated as full notional (i.e., zero equity recovery).

– Reverse repurchase agreements – Correlation exists where the underlying issuer and the counterparty are affiliated. In these cases, collateral used as an offset in the exposure calculation process is lowered to its recovery value.

Wrong-way risk monitoring

Regular reporting of wrong-way risk at both the individual trade and portfolio level allows wrong-way risk to be monitored and corrective action taken by CRM in the case of heightened concern.

– Country exposure reporting – Exposure is reported against country limits established for emerging market countries. As part of the exposure reporting process, exposures that exhibit wrong-way characteristics are given a higher risk weighting versus non-correlated transactions. This weighting results in a greater amount of country limit usage for wrong-way transactions.

– Counterparty exposure reporting – Transactions that contain wrong-way risk (e.g., repurchase agreements, equity finance) are risk weighted as part of the daily exposure calculation process. Correlated transactions utilize more of the credit limit.

– Correlated repurchase and foreign exchange reports – Monthly reports produced by CRM capture correlated finance and foreign exchange positions for information and review by CRM credit officers.

– Scenario risk reporting – In order to capture wrong-way risk at the industry level, a set of defined scenarios are run on the credit portfolio each month. The scenarios are determined by CRM and involve stressing the underlying risk drivers to determine where portfolios are sensitive to these stressed parameters.

– Scenario risk reporting also covers client groups, particularly hedge funds, which are exposed to particular risk sensitivities and also may have collateral concentrations due to the direction and strategy of the fund.

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. As of June 30, 2009, a downgrade would have resulted in the following aggregate additional collateral requirements:

– One notch downgrade – CHF 3.6 billion

– Two notch downgrade – CHF 5.1 billion

– Three notch downgrade – CHF 5.2 billion

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 planning. For further information on risk mitigation, refer to III – Treasury, Risk, Balance sheet and Off-balance sheet – Treasury management (pages 96 to 100) in the Credit Suisse Annual Report 2008.

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. The replacement values of derivative financial instruments correspond to their fair values as of the dates of the consolidated balance sheets and arise from transactions for both the accounts of customers and for our own account.

As of the end of 6M09, no credit derivatives were utilized that qualify for hedge accounting under US GAAP.

5. Securitization risk

The disclosures in this section refer to traditional and synthetic securitizations held in the banking book and regulatory capital on these exposures calculated according to the Basel II A-IRB approach to securitization exposures. A traditional securitization is a structure where an underlying pool of assets is sold to a special purpose entity which in turn issues securities that are collateralized by, and which pay a return based on the return on, the underlying asset pool. A synthetic securitization is a structure where the credit risk of an underlying pool of exposures is transferred, in whole or in part, through the use of credit derivatives or guarantees that 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 is active in various roles in connection with securitization, including originator, investor and liquidity provider. 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 also acts as liquidity provider to Alpine Securitization Corp. (Alpine), a multi-seller CP conduit administered by Credit Suisse. In addition, the Group invests in securitization-related products created by third parties.

For further information on traditional securitizations, including objectives, activities and accounting policies, refer to Note 32 – Transfers of financial assets and variable interest entities in V – Consolidated financial statements – Credit Suisse Group (pages 251 to 261) in the Credit Suisse Annual Report 2008 and Note 23 – Transfers of financial assets and variable interest entities in V – Condensed consolidated financial statements – unaudited (pages 110 to 119) in the Credit Suisse 2Q09 Financial Report.

Regulatory approaches

Regulatory capital requirements for securitization exposures are calculated in accordance with the Basel II A-IRB framework using either the RBA or the SFA, depending on the nature of the exposure.

Sources of external ratings for securitizations

External ratings used in regulatory capital calculations for securitization risk exposures are obtained from Fitch, Moody’s, Standard & Poor’s or Dominion Bond Rating Service.

6. Market risk

The majority of market risk is managed under the IMA approach. For further information on market risk, including information on risk measurement and VaR refer to III – Treasury, Risk, Balance sheet and Off-balance sheet – Risk management (pages 116 to 120) in the Credit Suisse Annual Report 2008. In addition, details on risk-weighted assets for market risk under the standardized approach, a description of the valuation process and details on the hedge funds capital add-on are included below.

Valuation process

The Basel II 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.

For further information on fair value, refer to II – Operating and financial review – Core Results – Fair valuations (pages 51 to 54) and – Critical Accounting estimates – Fair value (page 89) and Note 33 – Financial Instruments in V – Consolidated financial statements – Credit Suisse Group (pages 262 to 272) in the Credit Suisse Annual Report 2008.

Hedge funds

In 2008, FINMA introduced a stress-test-based capital add-on for hedge fund positions for Swiss banks using the IMA for trading book market risk. The capital add-on is based on the outcome of a series of stress tests taking into account the degree of diversification in the portfolio. These positions are also included in our VaR model, and the overall FINMA capital charge is the sum of the stress test add-on and the VaR.

8. Equity securities in the banking book

Overview

The classification of our equity 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 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, risk weights are determined using the IRB Simple approach based on the equity sub-asset type.

The numbers below are derived from the financial statements and differ from the numbers used for capital adequacy purposes. The main differences are the scope of consolidation (deconsolidation of private equity investments for capital adequacy purposes as we do not have a significant economic interest) 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.

For further information on risk measurement and management of our banking portfolios, refer to III – Treasury, Risk, Balance sheet and Off-balance sheet – Risk management (page 120) in the Credit Suisse Annual Report 2008.

Valuation and accounting policies of equity holdings in the banking book

For information on valuation and accounting policies of investment securities and trading assets, refer to Note 1 – Summary of significant accounting policies in V – Consolidated financial statements – Credit Suisse Group (pages 193 to 195) in the Credit Suisse Annual Report 2008.

9. Interest rate risk in the banking book

Overview

We have systems and controls in place to manage interest rate risk in the banking book. Risk sensitivity figures are provided for the impact of a one basis point change in interest rates, which is one of the primary ways in which these risks are assessed for internal risk management purposes. In addition, we confirm that the economic impacts of an adverse parallel shift in interest rates of 200 basis points and a statistical 1 year, 99% confidence adverse change in yield curves are significantly below the threshold of 20% of eligible regulatory capital used by regulators to identify banks that potentially run excessive levels of non-trading interest rate risk. Given our low levels of interest rate risk in the banking book, we do not have any regulatory requirement to hold capital against this risk, nor do we expect that the regulators will apply such a requirement in the future.

Management strategy and process

The interest rate risk exposures in our non-trading portfolios arise from a number of sources, including funding maturity mismatches, money market activities, long-term debt issuance, liquidity holdings, equity investment strategy and exposures to credit spreads.

Most material non-trading interest rate risk arises from the financial intermediation activities of the Private Banking division, resulting in non-trading directional interest rate risk embedded in the balance sheet. Those risks are transferred from the originating businesses to Treasury. Treasury then manages the risk position centrally within approved limits using hedging instruments such as interest rate swaps.

While the risks associated with fixed maturity transactions are transferred to Treasury by individual back-to-back transactions, certain products such as variable rate mortgages or savings deposits cannot be transferred in this way as those products do not have direct market-linked interest rates or contractual maturities. The interest rate risk associated with these products, referred to as non-maturing products, is estimated using the methodology of replicating portfolios and transferred to Treasury on a pooled basis. Based on the past behavior of interest rates and volume changes, this methodology assigns the position balance associated with a non-maturing banking product to several time bands. The methodology is based, where possible, on the principle of finding a stable relationship between the changes of client rates of the non-maturing product and an underlying investment portfolio. Where this is not possible, the maturity of the product is assessed based on volume stability only. These schedules can then be used to evaluate the product's 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. The methodology, maximum tenor and allocation of tranches in the replicating portfolios are ratified by the RPSC.

Interest rate risk also arises from the foreign exchange and interest rate positioning strategy with respect to our equity balance. The respective allocation strategy is defined by the CARMC and implemented by Treasury.

While the majority of our non-trading interest rate risk resides with Treasury or arises in conjunction with the interest rate positioning of our equity balance, some branches, subsidiaries and businesses also take on non-trading interest rate risk, which is managed within approved limits.

Risk measurement

The risks associated with the non-trading interest rate-sensitive portfolios are measured, monitored and limited using a range of tools, including the following key measures:

– Interest rate sensitivity (DV01): Expresses the impact of a one basis point (0.01%) parallel increase in interest rates on a portfolio's fair value. DV01 represents a transparent and intuitive (non-statistical) indicator of outright directional interest rate risk.

– Value-at-risk (VaR): Statistical indicator of the potential fair value loss, taking into account the probability of interest rate movements and observed correlations 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. VaR is calibrated to a 10-day holding period with a 99% confidence level and calculated using the historical simulation approach.

– Economic capital: Similar to VaR, economic capital represents a statistical risk indicator, taking into account market risks and other sources of risk, including counterparty exposure. Economic capital is calibrated to a 1-year holding period with a 99% confidence level.

– Economic value scenario analysis: Expresses the impact of a severe instantaneous change in interest rates on a portfolio's fair value. In particular, we assess compliance with regulatory requirements regarding appropriate levels of non-trading interest rate risk by estimating the economic impact of adverse 200 basis point parallel moves in yield curves and adverse interest rate moves calibrated to a 1-year holding period with a 99% confidence level and then relating those impacts to the total eligible regulatory capital. This analysis is performed for the Group and our major legal entities, including the Bank, on a monthly basis.

The measures listed above focus on the loss potential on a fair value basis taking into account the present value of all future cash flows associated with the current positions. Since non-trading books are not marked-to-market through earnings, the related accrual accounting impacts generally differ from the fair value impacts. In order to assess the risk profile in a manner consistent with the accounting basis, we periodically perform risk calculations of net interest income.

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 6M09 and 2008.

Impact of one basis point parallel increase of the yield curves
end of		6M09		2008

GBP		0.2		0.0
USD		6.9		5.5
Other		0.0		0.1
Total impact on the fair value of interest rate-sensitive banking book positions		8.1		5.3

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 6M09 and 2008, 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 in relation to the total eligible regulatory capital, was significantly below the 20% threshold 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.
