Cat Nat
France’s statutory natural-catastrophe insurance scheme
fraisrevu il y a 0 j
Short definition
A French legal regime that extends eligible property-damage policies to specified effects of a natural disaster recognised by decree. A national surcharge funds the scheme. Insurers may transfer part of the risk to CCR, whose unlimited cover benefits from a French state guarantee.

Why it matters now
