Lloyd’s Market Association Bulletin

The LMA’s Financial Institutions Committee has published two model cyber endorsements for use on Financial Institutions business – LMA5477A and LMA5479A – updates to LMA5477 and LMA5479, respectively.

The updated model endorsements each include the same ‘other insurance’ provision as LMA5478A, which was published in May 2025. 

Please note that capitalised terms that are defined in bold (e.g. Cyber Act) are defined in the endorsement. 

Capitalised terms that are not marked in bold (e.g. Loss) indicate terms that are defined in the underlying contract. Users may wish to amend the model endorsements as necessary to ensure these terms match those used in the underlying contract. Further guidance will be published by the LMA shortly.

LMA5477 and LMA5479 have been archived.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).
