8. Definitions Market Risk The risk that adverse price movements in the level or volatility of a price may create an anticipated loss. For example, a dramatic change in the interest rate during one day may create the risk of loss. Credit Risk The risk that a counterparty will not settle an obligation for full value, either when due or at a time thereafter.

9. But what about settlement risk? The guaranteeing of settlement of loan stock by SAFCOM brings in a new element of risk to SAFCOM, settlement risk Defined as: - The risk that a party will default on one or more settlement obligations due to no funds or securities

11. Risk and Margin Methodology MARKET RISK: - The Calm methodology was developed specifically for Yield- X. It is a conventional VaR (Value at Risk) calculation. The parameters which Yield-X uses in this calculation are one trading day (the loss is estimated over the period to the end of the next trading day) and 99.95% confidence level, which equates to Initial Margin. SETTLEMENT RISK: - Using the Calm methodology with the resultant figure computing to points per instrument, and applying rands per point, which equates to Settlement Margin.

12. Market Risk versus Settlement Risk MARKET RISK Where offset is allowed between Forward Bonds Where offset is allowed between Derivatives and Forward Bonds All Derivative products Forward Bonds SETTLEMENT RISK Where there is SFIDvP Only on S-3 of the transaction

13. Initial Margin versus Settlement Margin Offset between a Derivative and a Forward Bond where correlation exists Long Derivative Short Forward Bond = Offset = Initial Margin (Market Risk) S-3 Obligations are separated Long Derivative = Initial Margin (Market Risk) Short Spot Bond = Settlement Margin (Settlement Risk) Offset between Bonds Long Forward Bond R152 Short Forward Bond R186 = Offset = Initial Margin (Market Risk) S-3 Obligations are separated Long Spot Bond R152 = Settlement Margin Short Spot Bond R186 = Settlement Margin

14. Initial Margin versus Settlement Margin The calculation for both Initial Margin and Settlement Margin will be computed and the higher of the 2 will be taken on S-3 The unsettled position will be Marked-to-Market on EOD T+1, any short-fall will be requested as a Top-up Margin The Settlement Margin will be used as the Sweetener for Fails Management, i.e. Give-ups. Where Initial Margin is held (higher of the 2), surplus will be returned to the Clearing Member
