Actuarial work is changing, and the impact increasingly extends beyond the actuarial department. This session will look at several current developments, including principles-based reserving, lessons from LDTI, and the growing connection between investment decisions and actuarial results. Using real-world examples, we’ll explore why getting the calculation right is only part of the challenge, why modern reserving and reporting requirements require coordination across finance, IT, and operations, and how decisions made on the asset side can increasingly affect results on the liability side. Most importantly, we’ll discuss why these changes matter to the rest of the organization.
