Definition:Claims agreement traders (CAT)
🤝 Claims agreement traders (CAT) are specialized professionals within the Lloyd's of London market who facilitate the agreement and settlement of claims between syndicates and Lloyd's brokers on behalf of policyholders. The CAT system exists because a single Lloyd's policy is typically subscribed to by multiple syndicates, each bearing a percentage share of the risk. Without a structured agreement mechanism, settling a claim would require the broker to negotiate individually with every syndicate on the slip — an impractical process for a market that handles vast volumes of complex commercial and specialty claims.
⚙️ Under the claims agreement process, designated claims agreement parties — often experienced claims professionals employed by major managing agents or specialist claims service providers — are authorized to agree claims on behalf of subscribing syndicates. When a broker presents a claim, the lead underwriter typically reviews and agrees the claim first, after which claims agreement traders acting for following syndicates review the documentation and either agree or query the settlement. The process operates within the framework of Lloyd's claims procedures and market protocols, and it has been progressively modernized through electronic processing platforms aimed at reducing cycle times and improving data quality. The system hinges on trust and delegated authority: following markets place significant reliance on the lead underwriter's judgment and the competence of the CAT professionals reviewing claims on their behalf.
📋 The claims agreement trader role, while specific to the Lloyd's ecosystem, reflects a broader challenge inherent in subscription markets — namely, how to coordinate efficient claims handling when risk is shared among many parties. The profession requires a deep understanding of policy wordings, coverage interpretation, and market practice across lines ranging from marine and aviation to professional indemnity and property. As Lloyd's has pursued its modernization agenda — including initiatives to digitize the claims process and reduce the reliance on face-to-face market interactions — the role of CATs has evolved, but the fundamental need for specialist claims agreement expertise in a multi-party subscription environment remains a defining feature of how Lloyd's operates.
