Lloyd's of London

Industry

Definition

The world's specialist insurance and reinsurance marketplace, established in London in the 17th century. Lloyd's is not itself an insurance company but rather a marketplace where members join together in syndicates to underwrite insurance risks. The market separates capital provision (members) from underwriting expertise (managing agents). Lloyd's operates through a unique three-tier capital structure called the Chain of Security, which backs all policies written through the market. The Corporation of Lloyd's provides infrastructure and regulatory oversight, while syndicates conduct the actual underwriting. Lloyd's is known for insuring unique, complex, and high-value risks that may be difficult to place in standard markets.

Related Terms

Syndicate
A Lloyd's syndicate is formed by one or more members joining together to accept insurance risks at Lloyd's of London. Each syndicate sets its own appetite for risk, develops a business plan, arranges reinsurance protection, and manages exposures and claims. A syndicate is not a legal entity and is formed for a single calendar year called a year of account. At the end of the year, it may reform with identical or similar membership. Syndicates are managed by Managing Agents who employ underwriters and oversee day-to-day operations. Each syndicate is identified by a unique number and operates independently within the Lloyd's marketplace.
Managing Agent
A company authorized and regulated by the UK's Prudential Regulation Authority (PRA) and Financial Conduct Authority (FCA), as well as Lloyd's, that manages one or more syndicates on behalf of members at Lloyd's of London. Managing agents employ underwriters, oversee underwriting operations, manage infrastructure, handle day-to-day syndicate operations, and ensure compliance with regulatory requirements. They act as the operational arm of Lloyd's syndicates, executing the business plan and managing the syndicate's exposures and claims on behalf of the capital-providing members.
Coverholder
A company or partnership authorized by a Lloyd's Managing Agent to enter into contracts of insurance to be underwritten by syndicate members. Coverholders act as agents of the managing agent (not the policyholder) under a binding authority agreement. This delegation allows the coverholder to issue policies and handle claims within specified parameters without referring each risk back to the syndicate. Coverholders are typically located in markets outside London and provide local market access and expertise. They must comply with Lloyd's standards and are subject to oversight by the managing agent.
Excess and Surplus Lines
The non-admitted insurance market for risks that cannot be placed in the standard admitted market due to unique characteristics, high risk, or lack of available coverage. Excess and surplus lines insurers are not licensed (admitted) in the state where the risk is located, which provides them flexibility in rates and policy forms not subject to state prior approval requirements. However, they must meet financial requirements and are listed on state-approved eligible surplus lines insurer lists. The E&S market serves as a critical safety valve for the insurance system, providing coverage for unique, high-risk, or emerging exposures. Common E&S placements include high-value properties, unusual liability risks, and specialized commercial coverages. The U.S. surplus lines market exceeded $131 billion in direct premiums written in 2024, representing approximately 12% of the total property and casualty market.
Actuary
A business professional who analyzes probabilities of risk and risk management, including calculation of premiums, dividends, and other applicable insurance industry standards.
Underwriting
The process by which an insurer evaluates the risk of insuring a person or property and determines coverage terms and premium rates.
Loss Ratio
The ratio of losses paid plus loss reserves to premiums earned, used by insurers to measure underwriting profitability and pricing adequacy.
Combined Ratio
The sum of the loss ratio and expense ratio, measuring an insurer's overall underwriting profitability. A ratio below 100% indicates underwriting profit.
