International ERM Glossary

The International ERM Glossary is intended to provide users with a set of definitions that are in common usage around the world by actuaries, regulators and members of the insurance industry. The purpose in developing the glossary is to help provide a common understanding of the terms currently in use, as definitions and meanings have varied over time, and among practitioners. It can also be used as a training and educational tool for regulators.

The glossary can be consulted per letter, organization or grouping.
