Final answer:
A captive insurance agent is an employee who sells insurance exclusively for one insurer, differing from independent agents and brokers.
Step-by-step explanation:
An agent who is a salaried employee and sells insurance products exclusively for one insurer is known as a captive insurance agent. Unlike independent insurance agents, who represent multiple insurance companies, or brokers who work on behalf of clients rather than insurance companies, a captive insurance agent represents only one insurance company and is often bound by a contract to sell only that company's policies. This type of agent may receive a salary in addition to commissions or bonuses based on performance.
