From July to December of 2025, the Casualty Actuarial Society and its members were busy generating and publishing works that move the needle in actuarial practice. Whether those works were published on the CAS website, Actuarial Review, Variance, or elsewhere, these papers demonstrate the expertise and knowledge that CAS community delivers to the field globally. If you missed anything we launched in this period, you’ll find it listed here! Get ready to delve deeply into works that explore catastrophe risk, machine learning, and, of course, artificial intelligence.
