When insured parties experience a loss for a specified peril, the coverage entitles the policyholder to make a claim against the insurer for the covered amount of loss as specified by the policy. The fee paid by the insured to the insurer for assuming the risk is called the premium. Insurance premiums from many insureds are used to fund accounts reserved for later payment of claims – in theory for a relatively few claimants – and for overhead costs. So long as an insurer maintains adequate funds set aside for anticipated losses (called reserves), the remaining margin is an insurer's profit.
Upon termination of a given policy, the amount of premium collected minus the amount paid out in claims is the insurer's underwriting profit on that policy. Underwriting performance is measured by something called the "combined ratio", which is the ratio of expenses/losses to premiums.[25] A combined ratio of less than 100% indicates an underwriting profit, while anything over 100 indicates an underwriting loss. A company with a combined ratio over 100% may nevertheless remain profitable due to investment earnings.
Neither insurance consultants nor insurance brokers are insurance companies and no risks are transferred to them in insurance transactions. Third party administrators are companies that perform underwriting and sometimes claims handling services for insurance companies. These companies often have special expertise that the insurance companies do not have.

Insurance terms, definitions and explanations are intended for informational purposes only and do not in any way replace or modify the definitions and information contained in individual insurance contracts, policies or declaration pages, which control coverage determinations. Such terms may vary by state, and exclusions may apply. Discounts may not be applied to all policy coverages.


Liability insurance is a very broad superset that covers legal claims against the insured. Many types of insurance include an aspect of liability coverage. For example, a homeowner's insurance policy will normally include liability coverage which protects the insured in the event of a claim brought by someone who slips and falls on the property; automobile insurance also includes an aspect of liability insurance that indemnifies against the harm that a crashing car can cause to others' lives, health, or property. The protection offered by a liability insurance policy is twofold: a legal defense in the event of a lawsuit commenced against the policyholder and indemnification (payment on behalf of the insured) with respect to a settlement or court verdict. Liability policies typically cover only the negligence of the insured, and will not apply to results of wilful or intentional acts by the insured.

Annuities provide a stream of payments and are generally classified as insurance because they are issued by insurance companies, are regulated as insurance, and require the same kinds of actuarial and investment management expertise that life insurance requires. Annuities and pensions that pay a benefit for life are sometimes regarded as insurance against the possibility that a retiree will outlive his or her financial resources. In that sense, they are the complement of life insurance and, from an underwriting perspective, are the mirror image of life insurance.
Advanced economies account for the bulk of global insurance. With premium income of $1.62 trillion, Europe was the most important region in 2010, followed by North America $1.409 trillion and Asia $1.161 trillion. Europe has however seen a decline in premium income during the year in contrast to the growth seen in North America and Asia. The top four countries generated more than a half of premiums. The United States and Japan alone accounted for 40% of world insurance, much higher than their 7% share of the global population. Emerging economies accounted for over 85% of the world's population but only around 15% of premiums. Their markets are however growing at a quicker pace.[44] The country expected to have the biggest impact on the insurance share distribution across the world is China. According to Sam Radwan of ENHANCE International LLC, low premium penetration (insurance premium as a % of GDP), an ageing population and the largest car market in terms of new sales, premium growth has averaged 15–20% in the past five years, and China is expected to be the largest insurance market in the next decade or two.[45]
Many insurance executives are opposed to patenting insurance products because it creates a new risk for them. The Hartford insurance company, for example, recently had to pay $80 million to an independent inventor, Bancorp Services, in order to settle a patent infringement and theft of trade secret lawsuit for a type of corporate owned life insurance product invented and patented by Bancorp.

Wilson Company, ISBN 0-8242-0958-3 p. 121 The first life insurance company known of record was founded in 1706 by the Bishop of Oxford and the financier Thomas Allen in London, England. The company, called the Amicable Society for a Perpetual Assurance Office, collected annual premiums from policyholders and paid the nominees of deceased members from a common fund.
Muslim scholars have varying opinions about life insurance. Life insurance policies that earn interest (or guaranteed bonus/NAV) are generally considered to be a form of riba[64] (usury) and some consider even policies that do not earn interest to be a form of gharar (speculation). Some argue that gharar is not present due to the actuarial science behind the underwriting.[65] Jewish rabbinical scholars also have expressed reservations regarding insurance as an avoidance of God's will but most find it acceptable in moderation.[66]
In the United Kingdom, The Crown (which, for practical purposes, meant the civil service) did not insure property such as government buildings. If a government building was damaged, the cost of repair would be met from public funds because, in the long run, this was cheaper than paying insurance premiums. Since many UK government buildings have been sold to property companies and rented back, this arrangement is now less common and may have disappeared altogether.
