While using Monte Carlo simulations to calculate value at risk (VAR) for asset-based portfolios is well-established, it use in modeling VaR for risk events remains something of a mystery. This recorded webinar explores the principles behind Monte Carlo simulations, with a specific focus on risk events, and calculating VaR. Concepts covered: risk probability, risk impacts using distributions, percentiles and degrees of certainty, risk contribution by business unit or risk categories. Several practical examples are provided—you do not need to be a statistician to understand this presentation.
