Finalize the methodology proposed (Research/Market Risk) - determine the time period used to calculated forward-forward vols vs. correlations (20 days vs. 60 days) - stabilize the calculation for curves and time periods where the curve does not change based on historical prices, implying volatility of 0% 2. Get approval for the methodology change from Rick Buy (see draft of the memo attached) - John Lavorato and John Sherriff 3. Develop and implement the new methodology in a stage environment (Research/IT) 4. Test the new methodology (Market Risk, Traders) 5. Migrate into production (Research/IT) Please let me know if this is reasonable and meets everyone's expectations. Vlady.
