Description: The CAS is pleased to present its Research Paper, “Users’ Guide to Economic Scenario Generation in Property-Casualty Insurance”. Although there are cases in the literature about the use of economic scenario generators (ESGs) in the property casualty industry, they are far more commonly used for life insurance companies. Our hope is that this paper will serve as a comprehensive guide to the implementation of ESGs in the non-life space and spark interest in research into new applications of ESGs.

Description: There will be inflection points in the value of an instrument when interest rates change. These inflection points could materially impact the approximation of value change using ALM metrics. In this part of the seven-part series, I will highlight: • How to identify the inflection points; • the range of rate changes where ALM metrics may be relied upon i.e., the “validity” range, outside of which recalculation of the ALM metrics is required and the potential that one needs to rebalance the portfolio; • a technique to improve on the approximation of value change beyond the validity range; and • a technique to convert non-linear change on the yield curve to be used with duration and convexity.
