Certain insurance products and practices have been described as rent-seeking by critics.[citation needed] That is, some insurance products or practices are useful primarily because of legal benefits, such as reducing taxes, as opposed to providing protection against risks of adverse events. Under United States tax law, for example, most owners of variable annuities and variable life insurance can invest their premium payments in the stock market and defer or eliminate paying any taxes on their investments until withdrawals are made. Sometimes this tax deferral is the only reason people use these products.[citation needed] Another example is the legal infrastructure which allows life insurance to be held in an irrevocable trust which is used to pay an estate tax while the proceeds themselves are immune from the estate tax.
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.
In the United States, the most prevalent form of self-insurance is governmental risk management pools. They are self-funded cooperatives, operating as carriers of coverage for the majority of governmental entities today, such as county governments, municipalities, and school districts. Rather than these entities independently self-insure and risk bankruptcy from a large judgment or catastrophic loss, such governmental entities form a risk pool. Such pools begin their operations by capitalization through member deposits or bond issuance. Coverage (such as general liability, auto liability, professional liability, workers compensation, and property) is offered by the pool to its members, similar to coverage offered by insurance companies. However, self-insured pools offer members lower rates (due to not needing insurance brokers), increased benefits (such as loss prevention services) and subject matter expertise. Of approximately 91,000 distinct governmental entities operating in the United States, 75,000 are members of self-insured pools in various lines of coverage, forming approximately 500 pools. Although a relatively small corner of the insurance market, the annual contributions (self-insured premiums) to such pools have been estimated up to 17 billion dollars annually.[40]
Cheap, sub-standard auto carriers write insurance for insureds with bad driving records. They are able to do this by setting their own limited conditions under which they will provide coverage. These sub-standard carriers do not cover claims that would be covered under a more standard policy. These policies can contain “named-driver exclusions” which limit coverage to persons specifically named in the policy. “Step-down” policies often lower liability coverage to a state’s minimum limits for permissive users, even if the insured pays for higher limits. Deductibles can be higher and/or a policy won’t extend coverage to a rental vehicle. Therefore, policy terms vary and directly affect whether a particular coverage follows the car or the driver.
The insured receives a contract, called the insurance policy, which details the conditions and circumstances under which the insurer will compensate the insured. The amount of money charged by the insurer to the Policyholder for the coverage set forth in the insurance policy is called the premium. If the insured experiences a loss which is potentially covered by the insurance policy, the insured submits a claim to the insurer for processing by a claims adjuster. The insurer may hedge its own risk by taking out reinsurance, whereby another insurance company agrees to carry some of the risk, especially if the primary insurer deems the risk too large for it to carry.
In the United States, insurance is regulated by the states under the McCarran-Ferguson Act, with "periodic proposals for federal intervention", and a nonprofit coalition of state insurance agencies called the National Association of Insurance Commissioners works to harmonize the country's different laws and regulations.[46] The National Conference of Insurance Legislators (NCOIL) also works to harmonize the different state laws.[47]
Insurance company claims departments employ a large number of claims adjusters supported by a staff of records management and data entry clerks. Incoming claims are classified based on severity and are assigned to adjusters whose settlement authority varies with their knowledge and experience. The adjuster undertakes an investigation of each claim, usually in close cooperation with the insured, determines if coverage is available under the terms of the insurance contract, and if so, the reasonable monetary value of the claim, and authorizes payment.
Protected self-insurance is an alternative risk financing mechanism in which an organization retains the mathematically calculated cost of risk within the organization and transfers the catastrophic risk with specific and aggregate limits to an insurer so the maximum total cost of the program is known. A properly designed and underwritten Protected Self-Insurance Program reduces and stabilizes the cost of insurance and provides valuable risk management information.
These are on the high side, but there are still instances in which they won’t be enough to fully cover you. For example, if you accidentally hit a luxury car, replacing it could easily cost more than the $25,000 legal minimum for property damage coverage. If the other driver is injured, their medical bills could also exceed the $30,000 bodily injury minimum fairly easily. In each case, you’d be responsible for making up the difference yourself.
Calculable loss: There are two elements that must be at least estimable, if not formally calculable: the probability of loss, and the attendant cost. Probability of loss is generally an empirical exercise, while cost has more to do with the ability of a reasonable person in possession of a copy of the insurance policy and a proof of loss associated with a claim presented under that policy to make a reasonably definite and objective evaluation of the amount of the loss recoverable as a result of the claim.

When you apply for auto insurance in Texas, providers are legally required to offer $2,500 in Personal Injury Protection coverage (PIP). This type of coverage is mandated in so-called “no-fault” states, but it’s optional in Texas (although you do have to refuse it in writing). If you select it, 100% of the coverage amount will be available for your medical bills following an accident, regardless of who was at fault. While you may be covered under your own health insurance for those costs, PIP has the added benefit of covering up to 80% of your lost income if you’re unable to work following an accident. It’s a nice protection, but keep in mind that $2,500 won’t go that far in such a case. While most companies will let you raise the limit, it’s one of the costlier options to add, so if you’re on a budget, you’ll have to weigh its value against things like comprehensive and UM/UIM coverage.
