Term that denotes that a reinsurance contract will follow the underlying risk. It does not mean following the insurance terms and conditions in their entirety. As original’ serves to define the risk (e.g. period of cover, geographical limits, the nature) so that reinsurers and insurers face exactly the same risk (Pine Top v. Unione Italiana Anglo Saxon). There is a presumption against incorporation into the reinsurance contract of collateral clauses (e.g. jurisdiction clause) from the underlying contract. However, the term is presumed to make warranties as significant to the reinsurance policy as to the insurance contract (Groupama Navigation et Transport & Others v. Caiaiumbo CA Seguros).
