Zurich Actuarial Society

The Zurich Actuarial Society ('the Society' or 'ZAS') is a regional community working with the Institute and Faculty of Actuaries (IFoA)

Zurich Actuarial Society (ZAS) has the following objectives:

  • to engage with all actuaries (not just members of the IFoA) in the wider Zurich area
  • to provide opportunities for networking and CPD
  • to liaise with academia
  • to create a bridge with local actuarial groups.


Any member in good standing of the IFoA or any equivalent actuarial professional body is eligible to become a member of the Society

The Committee at its sole discretion may admit as a member anyone else provided that person's membership is consistent with achieving the objectives of the Society.

Membership of the Society is free of charge.
