The following is a list of common Insurance Terms:

Actuary - A specialist in the mathematics of insurance who calculates rates, reserves, dividends and other statistics. While sometimes the term is used loosely, the title Actuary really belongs to those who meet the requirements of one of the Actuarial Societies, the Casualty Actuarial Society (CAS), for Property and Casualty Insurance, or the Society of Actuaries (SOA), for Life and Health Insurance. To qualify for membership in these associations, the individual must pass a number of extremely difficult technical mathematical examinations. Because of the rigorous requirements for membership, Actuaries, are very much in demand in the insurance industry and command very high salaries.

Adjuster - Usually a representative of the insurer who seeks to determine the extent of the insurer's liability for loss when a claim is submitted. There are also independent adjusters who will work on the behalf of the insured party to negotiate a settlement with the insurer.

Agent - An individual who represents or acts as the agent of an insurance company in selling and servicing insurance policies.
There are two kinds of agents:

1. Independent agent represents at least two insurance companies and (at least in theory) services clients by searching the market for the most advantageous price for the most coverage. The agent's commission is a percentage of each premium paid and includes a fee for servicing the insured's policy.
2. Direct or career agent represents only one company and sells only its policies. This agent is paid on a commission basis in much the same manner as the independent agent.

Broker - An insurance professional who works on behalf of a client (the insured) to find insurance for that client. A broker differs from an agent in that the agent works on behalf of the insurance company and is compensated by the company. Brokers are compensated primarily based on fees they charge the client, although some brokers may also collect some compensation from insurers.
In theory, a broker is supposed to work with the client to identify and understand their insurance needs, then to survey the marketplace to find the best combination of coverage and price for their client.

Captive Agent - Representative of a single insurer or group of insurers who is obliged to submit business only to that company, or at the very minimum, give that company first refusal rights on a sale. In exchange, that insurer usually provides its captive agents with an allowance for office expenses as well as employee benefits such as pensions, life insurance, health insurance, training and credit unions.

Casualty - Liability or loss resulting from an accident.

Casualty Insurance - That type of insurance that is concerned with losses caused by injuries to persons and the legal liability imposed upon the insured for such injury.

Chartered Property and Casualty Underwriter (CPCU) - A professional designation earned after the successful completion of 10 national examinations given by the American Institute for CPCU .

Three years of work experience also are required in the insurance business or a related area.

Claim - A demand made by the insured, or the insured's beneficiary, for payment of the benefits as provided by the policy.

Combined Ratio - The sum of the losses paid out or reserved, expenses other than claims, and policyholder dividend ratios not reflecting investment income or income taxes, divided by the premiums earned.
This ratio measures the company's overall underwriting profitability. A combined ratio of less than 100 indicates an underwriting profit. For example, a combined ratio of 98 would mean that the insurance company made a 2% profit on its underwriting operations (not counting any money made from investment income).

For example, an insurer would earn $100 every month on a policy that has a premium amount of $1,200.00 and is written for a 12-month period. If a policy cancels before the end of its term, the insurance company will only earn the proportional amount of the total premium.
