Spot/Forward curve models are widely used; Single factor Multi factor Path dependant Jump diffusion One absolute truth about modelled forward curves is that they are always wrong. Simulated Values Time Portfolio Value Known Current Value Gas UK 01/06/2008 18/12/2008 06/07/2009 22/01/2010 10/08/2010 26/02/2011 0.8 0.7 0.6 0.5 0.4 0.3 0.2 0.1 0 £

5. 5 Trading products OTC/Bi-lateral contracts/forwards Can be physically or financially settled. (UK- physical) Buy/Sell Natural gas at an agreed price (fixed or formula) Agreement between two counterparties Delivered (if physical) over a time horizon in the future Payment after delivery (typically 30 days) Governed mainly by EFET, ISDA along with NBP which acts as a framework agreement. Futures Special type of forward contract Highly standardised contract terms (ie delivery, grade, volume, etc) Traded on exchanges Typically settles financially (EFP is physical).

8. 8 Risk Measurement Various tools and concepts are used to measure different types of risks; Price Risk – Value At Risk (VaR), CFaR, PaR i.e. One day 95% VaR of £5m means that we would not expect our loss on the portfolio, over a 1 day period, to exceed £ 5m more then 5% of the time, or 1 in 20 independent one day period Credit Risk – Potential future exposure (PFE), CVaR Liquidity Risk – Contingent Capital, Margin At Risk Model Risk - don’t fall in love with your models !
