Insurance involves pooling funds from many insured entities (known as exposures) to pay for the losses that some may incur. The insured entities are therefore protected from risk for a fee, with the fee being dependent upon the frequency and severity of the event occurring. In order to be an insurable risk, the risk insured against must meet certain characteristics. Insurance as a financial intermediary is a commercial enterprise and a major part of the financial services industry, but individual entities can also self-insure through saving money for possible future losses.[15]
Defense Base Act (DBA) insurance provides coverage for civilian workers hired by the government to perform contracts outside the United States and Canada. DBA is required for all U.S. citizens, U.S. residents, U.S. Green Card holders, and all employees or subcontractors hired on overseas government contracts. Depending on the country, foreign nationals must also be covered under DBA. This coverage typically includes expenses related to medical treatment and loss of wages, as well as disability and death benefits.
You should also look into how the company handles the claims process, as the single biggest indicator of home insurance customer satisfaction is the company’s damage estimates. If they have a reputation for not covering the agreed-upon replacement costs of property or dropping customers from their policy for filing a single claim, you should probably avoid that company.
Comprehensive car insurance covers damage to your car if it collides with something other than another car, like an animal or a tree, or if it’s damaged by vandalism, theft, or natural disaster. Again, if you lease your car or have an outstanding loan on it, this type of coverage will be required, but if you pay your car off, or it becomes worth less money than it would cost to repair, you can decline this coverage.
In the United States, economists and consumer advocates generally consider insurance to be worthwhile for low-probability, catastrophic losses, but not for high-probability, small losses. Because of this, consumers are advised to select high deductibles and to not insure losses which would not cause a disruption in their life. However, consumers have shown a tendency to prefer low deductibles and to prefer to insure relatively high-probability, small losses over low-probability, perhaps due to not understanding or ignoring the low-probability risk. This is associated with reduced purchasing of insurance against low-probability losses, and may result in increased inefficiencies from moral hazard.[56]
In July 2007, The Federal Trade Commission (FTC) released a report presenting the results of a study concerning credit-based insurance scores in automobile insurance. The study found that these scores are effective predictors of risk. It also showed that African-Americans and Hispanics are substantially overrepresented in the lowest credit scores, and substantially underrepresented in the highest, while Caucasians and Asians are more evenly spread across the scores. The credit scores were also found to predict risk within each of the ethnic groups, leading the FTC to conclude that the scoring models are not solely proxies for redlining. The FTC indicated little data was available to evaluate benefit of insurance scores to consumers.[58] The report was disputed by representatives of the Consumer Federation of America, the National Fair Housing Alliance, the National Consumer Law Center, and the Center for Economic Justice, for relying on data provided by the insurance industry.[59]
Claims and loss handling is the materialized utility of insurance; it is the actual "product" paid for. Claims may be filed by insureds directly with the insurer or through brokers or agents. The insurer may require that the claim be filed on its own proprietary forms, or may accept claims on a standard industry form, such as those produced by ACORD.
In many cases, the legal minimum insurance won’t be enough to cover costs if you cause an accident. If you total someone’s luxury car, for example, their repair costs could easily exceed a $25,000 ceiling. Any damage that surpasses your limits has to come out of your own pocket. That’s why for most drivers it’s wise to select higher limits, such as 100/300/50.
One of the big perks of insuring your home through Metlife is that they offer guaranteed replacement cost coverage – meaning if your home or stuff is damaged or destroyed by a covered peril, your home’s rebuild costs and property will receive the full replacement cost, depreciation notwithstanding. That means if your home is only worth $250,000 but it costs $500,000 to replace, Metlife will pay the full $500,000 to replace your home.
Next, take a good hard look at your driving record and credit report, and clean both up if they’re not in good shape. Moving violations, citations for driving under the influence, accidents, and a low credit score all tell car insurance companies you’re at higher risk of being in an accident, making a claim, and costing them money. Some car insurance companies will give you a discount if you can prove you’re a safe driver by installing a tracking device in your car, which can lead to lower rates over time (however, if the tracker shows you routinely drive in an unsafe manner, your rates might go up). A few years without a citation or an accident, as well as a steadily improving credit score, can help you save on car insurance.

Naturally, the float method is difficult to carry out in an economically depressed period. Bear markets do cause insurers to shift away from investments and to toughen up their underwriting standards, so a poor economy generally means high insurance premiums. This tendency to swing between profitable and unprofitable periods over time is commonly known as the underwriting, or insurance, cycle.[29]
Large number of similar exposure units: Since insurance operates through pooling resources, the majority of insurance policies are provided for individual members of large classes, allowing insurers to benefit from the law of large numbers in which predicted losses are similar to the actual losses. Exceptions include Lloyd's of London, which is famous for ensuring the life or health of actors, sports figures, and other famous individuals. However, all exposures will have particular differences, which may lead to different premium rates.
