Updated Model Cyber Clauses for Contingency Business

The LMA’s Contingency Business Panel has published two updated model cyber clauses for use with event cancellation and non-appearance policies – LMA5591A and LMA5592A.

Changes include an amendment to paragraph 3 and the addition of a reverse onus of proof provision.

Please note, these clauses replace LMA5591 and LMA5592, respectively, which have been archived.

All LMA model documents are purely illustrative and are published and distributed for the guidance of Lloyd’s managing agents, brokers and other market participants. All contracting parties are free to agree to different conditions/amend the model documents as they see fit; the LMA does not protect its intellectual property rights over model documents. It is for underwriters to decide whether or not any contractual language is acceptable on any given risk. Model documents are available on the Lloyd’s Wordings Repository (LWR).
