Finance delegates to CIB Finance the supervision of the entire P&L and valuation control process
CIB Finance responsibility is carried out through “CIB Financial Control” and the coordination of the governance structure
CIB Financial control is a “global” finance control function which is responsible for supervision of the entire Valuation and P&L Control framework (which includes 1st and 2nd level controls) across capital market activities, global coordination (prepares and drives the monthly Committees that examine all issues relating to valuation, P&L and system booking)
The responsibility is shared by many players, each of them is responsible for their respective perimeter

Based on the charter of responsibilities, which defines the breakdown of responsibilities on the valuation and P&L controls, the organization is placed under the supervision of the Finance function
Finance guarantees the production and the quality of the Group financial statements and Group Management accounts
Finance uses to delegate the production and control of the financial instruments’ fair value, to the various participants
Finance delegates to Risk the authority to control the fair value of the financial instruments booked in the Group accounts (models, parameters)

Environment analysis:
Vacuum of the snapshot
Heterogenity& asynchronicity
To validate a model is not strictly limited to a quantitative review. The environment and the internal organisation’s «fit» is also tested
Reviewing a model should encompass:
The model operating environment includes:

13. 13
Is the model answering all the bank expectations?
What is the trading strategy?
What are the criteria for validating a model?
Risk of mispricing? (new model, strong assumptions, strong hypothesis …)
Very sensitive model? (Greeks and parameter sensitivities are high …)
Risk of P&L swings? Easy to Hedge or not? Very expensive to hedge?
Complex to follow or not? (change in portfolio composition / change in the underlying maturities …)
Risk of arbitrage?
No benchmark? Mark to Model? (no market price, partial quotes …)
Illiquid market? (higher bid-ask spreads…)
Instability of the model under stress conditions?
Regulatory risk? (Arbitrage in ISDA or CSA contracts …)
Capital requirement is too high? (Basel III, cash collateral requirements …)
Avoid gamma holes
When volatility is high, gamma is high, hedging is expensive
Large gamma may show imperfect hedge and possible jumps in PnL(barrier options)
When gamma changes sign (spread options), delta hedge is not possible
Monetize variance risk premia
Sell implied, buy realized volatility by creating a flat dollar gamma portfolio, go long gamma
Volatility term structure arbitrage
After the crisis we expect short volatility to decrease and long volatility to increase
Sell short volatility, buy long volatility by delta hedged straddles
Smile arbitrage
Volatilities are extremely volatile, but volatility smile is always flat
Sell straddle, buy butterfly
Monetize liquidity risk premium
Borrow on short-term, lend on long-term

Our approach to model review | An integrated, iterative and proven Model reviewobjectives servedby CH&Cie powerfultools
The objectives of the review are to:
To ensure your model meets each requirement of the regulation (including technical standards);
To ensure the quality and soundness of the modelling principles on which your framework is based;
To gain comfort on the model calibration, back-testing and stress-testing of the margins;
To identify the model limits and if needed assess the materiality of lump add-ons required to cover the risk; and
To the extent feasible, propose a benchmark analysis and suggest state-of-the-art enhancements.

Our approach to model review | An integrated, iterative and proven Model reviewphased approach
By or across product lines, CH&Cie is reviewing model documentation and testing methodology performed by internal teams with the following phased approach:
Liaise with institution market risk manager to obtain detailed model methodology/policy and validation documentation. This should contain:
•Rationale for the selected model
•Key model assumptions and provisions
•Data sources, parameter definition and model calibration procedures
•Calculation framework and frequency
Identify institution existing VaRtesting procedures to review scope, relevance and results under calibrated parameters (market regime, confidence level, look back period…)
•Assess risk factor relevance, return calculation, depth and source
•Define standard parameters and calibrate model accordingly
•Compare VaRand expected shortfall
Prepare test scenarios that can be run independently to verify VaRimpact and model performance (back testing, input parameter sensitivity, stress testing) and compare with institution results. For instance, we will “fine-tune” parameters such as:
•Risk measure/number of breaches, confidence level, look-back period, scale vol, correlations, decay factor…
•Description of the tests performed
Sample a representative portfolio and simulate scenarios for additional comparison between institution and CH&Cie model, using back testing at risk factor level.

Our approach to model review | An integrated, iterative and proven Model reviewdeliverables
This model review shall include:
An evaluation of the conceptual soundness of the model and framework;
A review of the on-going monitoring procedures such as daily margin coverage and back-testing;
A review of the parameters and assumptions made in the development of its models, their methodologies and the framework including an assessment of the theoretical and empirical properties of the margin model;
A review of the adequacy and appropriateness of the models, their methodologies and framework adopted in respect of the type of contracts they apply to;
A review of add-ons to the base model;
An analysis of the outcomes of testing results against institution performance criteria;
A review of the diversification benefits of the model;
A review of the margin period of risk;
An assessment of pro-cyclical effects and how such affects are mitigated;
An assessment of margin model sensitivity to the material risk factors and correlations to which the institution is exposed;
A review of pricing models; and
A review of model documentation

Adaptingouroffer& expertise to the evolvingneedsof ourclients
Fuelled by the need to limit conflict of interest, to reduce risks and meet regulatory requirements, banks are building longer term relationships focusing on client satisfaction.
Since 2007, the erosion of the profitability of the banking sector surged financial institutions towards a better management of their risk environment. We believe managing risks is about understanding all banking activities, as well as the dynamics of their interactions. Risk modelling is therefore cross- disciplinary and transversal across
