Article 5.2
(Event-based aggregation)
(1) Where the parties agree on an event-based aggregation in a contract reinsuring first-party insurance policies, all losses that occur as a direct consequence of the same materialization of a peril reinsured against shall be considered as arising out of one event.
(2) Where the parties agree on an event-based aggregation in a contract reinsuring third-party liability insurance policies, all losses that occur as a direct consequence of the same act, omission or fact giving rise or allegedly giving rise to the primary insured’s liability shall be considered as arising out of one event.
