They differ from insurance agents, who sell policies under contractual agreements with insurance companies. Brokers act in the interest of insurance buyers. They have no authority to bind coverage or issue policies. To initiate coverage on behalf of an insurance buyer, a broker must ask an underwriter at the insurer to issue an insurance binder.
Broad Range of Services
Large brokers provide a broad range of services. While the specific services provided vary from broker to broker, many offer the following:
Risk management services
Loss control services
Claims management services
Private client services (personal coverages for wealthy individuals)
Analytics (such as loss forecasting)
Captives and other forms of alternative risk transfer
Affinity programs (insurance programs designed for groups, such as franchises)
Several of the largest brokers operate worldwide, maintaining offices in numerous foreign countries.
Examples are Marsh, AON, and Willis. Others, such as USI and BBT, operate mainly in the United States. Some, like Wells Fargo and BB&T, are insurance subsidiaries of financial conglomerates.
