Description: This article will further discuss decentralized and centralized model development frameworks and provide tips and rationale for transitioning toward centralized model development.

Description: The SOA is interested in understanding how companies are performing scenario analysis, thinking through how various stakeholders (regulators, general public, competitors) could be reacting to a large-scale large-impact event over a multi-year period.

Description: The Actuaries Climate Index has been updated with new quarterly data, revisions to initial data for previous periods, and annually updated values for the index’s drought and sea level components.

Description: This is a synopsis of a report that actuaries have been participating in regarding insurer risk assessment for solvency purposes.

Description: This article delves into general insurance questions raised by the recent CrowdStrike disruption on computer systems worldwide.

Description: This article offers a comprehensive approach for “lean” model risk management (MRM), i.e., the management of an MRM program with few or possibly one employee devoted to the role. It explores key objectives of an MRM program, essential process elements, tips for efficiency, and examine the use of artificial intelligence (AI) in the models themselves and as a tool to increase efficiency of the program.

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.

Description: The 2024 Dangerous Risks survey shows respondents react to recent increases in "old favorite" risks as technology evolves and the environment moves away from the pandemic.

Description: This article will highlight the issue that the sum of key-rate metrics does not add to metrics derived by parallel shift to the entire curve, even at very low shift size. Additionally, in the article I will outline how to define a single rate change to be applied to a key rate (or the entire curve) since the rate changes are generally not level or parallel.

Description: An introductory article describing how Bayesian statistics has evolved over the past 20 years and why it offers the actuarial discipline powerful tools to better understand and manage risk. Compared with traditional (frequentist) and black-box (machine learning) approaches, Bayesian analysis provides explainable models focused on distributions of estimates instad of simply point estimates.
