Amidst the recent flurry of activity around AI, actuaries will be in good company as they consider how to extract the benefits of AI advancements, while avoiding their downside risks. Actuaries that develop and deploy AI systems must consider how to deliver the potential gains in accuracy and speed, while avoiding risks like biased decision-making. At the same time, they must carefully consider how AI systems will integrate into employee workflows. Responsible AI and human-centric AI offer valuable guidance to address these issues and can assist actuaries in realising the benefits of AI.

The additive reserving model assumes the existence of volume measures such that the corresponding expected loss ratios are identical for all accident years. While classical literature assumes these volumes are known, in practice, accurate volume measures are often unavailable. The issue of uncertain volume measures in the additive model was addressed in a generalization of the loss ratio method published in 2018. The derivation is rather complex and the method computationally intensive, especially for large loss development triangles.
We present an alternative approach that leverages the well-established EM algorithm, significantly reducing computational requirements.

This webinar will explore new practice areas for actuaries in the context of climate change. It aims to provide a broad overview of areas where actuaries can apply their skills and expertise to assist with climate change risks and opportunities, and thereby support the transition to a low-carbon economy, whilst also helping to manage the risks associated with such a transition (including not transitioning). The session will draw on current literature, case studies, industry practice and stakeholder interviews. The session covers current and potential areas of practice relating to climate risk management, risk and emissions modelling, insurance, finance and investments, strategy setting, governance, reporting and regulation, government, and other areas of corporate support. The webinar also addresses, at a high level, areas in which actuaries will be required to enhance their technical climate knowledge to enable actuarial practice.

This talk presents a method for constructing insurable risk portfolios using a data-driven approach to devise risk retention programs that safeguard firms from a multitude of risks. Because firms face many risks, including fire damage to their buildings, liability from management misconduct, and external threats like cyber attacks, this talk treats these potential liabilities as a "portfolio." Drawing inspiration from Markowitz portfolio theory, it leverages techniques from probability, statistics, and optimization to build algorithms that construct optimal risk insurable portfolios under budget constraints. Through engaging case studies, viewers will learn how to build optimal insurable risk portfolios.
The talk illustrates a frontier that depicts the trade-off between the uncertainty of a portfolio and the cost of risk transfer. This visual representation, mirroring familiar Markowitz investment tools, enables informed decision-making and easy adoption by risk advisors. The talk outlines the mathematical groundwork for constructing optimal insurable risk portfolios in an effective and aesthetically pleasing manner.

In this session we explore how the localized nature of severe weather events leads to a concentration of correlated risks that can substantially amplify aggregate losses. We propose a copula-based regression model for replicated spatial data to characterize the dependence between property damage claims from a common storm. The factor copula captures spatial dependence between properties and aspatial dependence induced by the common shock. The framework allows insurers to incorporate heterogeneity in marginal models of skewed, heavy-tailed, and zero-inflated insurance losses, while retaining model interpretation. Using hail damage insurance claims data from a US insurer, we demonstrate the effect of dependence on claims management decisions.

Join us for a rousing, informative presentation on a controversial and timely topic that delves into whether actuaries should engage in the political discourse on Climate Change—and whether doing so strengthens or undermines the profession.

This webinar explores the following key questions:
💠Should the actuarial profession be making pronouncements about Climate Change when it manifestly lacks the necessary expertise on the topic?
💠Should actuaries stay out of the political debate on Climate Change?
💠Does it help the profession to comment on topics not covered in the syllabus?
