NEWLY REVISED Each year, the Reinsurance Association of America (RAA) receives countless inquiries regarding the mechanisms and technicalities of the reinsurance business. This publication should answer many of those questions. First published in 1972 and newly revised in 2016, this booklet reflects the efforts and input of several of the most experienced reinsurance terminology experts in the industry. It is only through their efforts that we are able to produce such a complete and accurate publication, and we thank them for their time, patience and willingness to contribute. As in the case of previous editions, the RAA is publishing this booklet in the belief that it will be both an informative educational tool and a convenient reference for practitioners. While we have attempted to ensure that definitions reflect current industry practices, we do not suggest that it be considered authoritative for the resolution of legal disputes.
