September 2005 Page - 9  Minimum capital requirement comprise two aggregates:  In compliance with Regulation no. 91-05 of February 1991 – and all further amendments of calculation methods delivered thereafter – any IF must report to the regulatory authorities an amount of capital necessary to face an adverse situations leading to liquidity requirements. This calculation is based on : 1.An equivalent risk amount to cover losses due to adverse market movements: this amount is derived from the sensibility of open positions to market movements, measured either by VaR or Greeks. 2. An “equivalent credit risk” to cover counterparty default : all open trading positions with a given counterparty bear a risk of loss if the counterparty defaults. This amount is calculated on a trade basis and is derived form the nominal (% of the nominal as potential future loss) and the current MTM (% of the current MTM as replacement risk) of the transaction. It is aggregated at counterparty level, taking into account whatever netting agreement or risk mitigation there might be between the company and its counterparty. Investment Firm statutory requirements

10. September 2005 Page - 10 This equivalent Credit Risk is computed – on an individual trade basis - by the following formula : ECR = Weighting contrepartie x (Potential Future Loss + Replacement Risk) whereby : The weighting contrepartie depends on the nature of the counterparty : 0% for an institutional or a state, 20% for banks and other IF firms, and 50% for any other counterparty (art. 4.3.2. & art 4.2 of Regulation 91-05) ; The replacement risk equals “netting factor” * Max (0, MTM), in case there is a netting agreement between us and the counterparty ; The potential future loss depends on the Nominal amount, the residual maturity and the underlying (commodities, stocks, bonds …). On top of this, receivables are also taken into account as amount at risk and added to this figure. Investment Firm statutory requirements
