Purpose

Policies placed at Lloyd’s and in the London company market are usually carried by several underwriters, each taking a specific share of the risk. The several liability clause (LMA3333, successor to the older LSW1001) makes unambiguously clear that each underwriter’s liability is limited to its own underwritten proportion and is not joint with the other underwriters.

Effect and limits

If one underwriter defaults, for example through insolvency, the shares of the remaining underwriters do not automatically increase; the policyholder therefore bears an independent default risk for each underwriter. For Lloyd’s syndicates, the clause additionally clarifies that, legally, it is not the syndicate as a whole but its individual members (Names) who are liable, each for its own proportion. Signed lines can subsequently adjust the originally written lines and prevail over them in the event of a dispute.

Negotiation and practice

For layered or subscription policies, programme leaders should assess the credit quality and diversification of the participating underwriters, since a default by one is not compensated. Combined with an act-as-one clause for arbitration, the several nature of liability can be prevented from also producing separate, uncoordinated proceedings where several underwriters are involved.
