• the a number of flavors of price in danger in addition to extra portfolio metrics.
• tips to hyperlink objective debts and threat coverage and view the effect of either on designing hazard platforms.
• Monte Carlo simulation in Excel for simulating commodity costs, projecting company P&L and reading hedge effectiveness.
