At the most basic level, initial ratemaking involves looking at the frequency and severity of insured perils and the expected average payout resulting from these perils. Thereafter an insurance company will collect historical loss data, bring the loss data to present value, and compare these prior losses to the premium collected in order to assess rate adequacy. Loss ratios and expense loads are also used. Rating for different risk characteristics involves at the most basic level comparing the losses with "loss relativities"—a policy with twice as many losses would therefore be charged twice as much. More complex multivariate analyses are sometimes used when multiple characteristics are involved and a univariate analysis could produce confounded results. Other statistical methods may be used in assessing the probability of future losses.

Collision coverage is probably the most important coverage you need to have in order to protect your vehicle against physical damage. It is not difficult to accidentally hit something when driving. Somebody is always at fault, and that someone could be you. Some of the most significant damage to your vehicle can come from a collision with another vehicle, tree, pole or guardrail. In order to purchase collision coverage, you’ll need to purchase basic coverage as well. The higher your deductible (the amount you pay if you do get into a collision), the lower your monthly payments will often be — and this can be the best way to get the coverage you need and the savings you deserve at the same time.
NerdWallet averaged rates for 40-year-old men and women for 20 ZIP codes in each state and Washington, D.C., from the largest insurers, up to 12 in each state. “Good drivers” had no moving violations on record and credit in the “good” tier as reported to each insurer. For the other two driver profiles, we changed the credit tier to “poor” or added one at-fault accident, keeping everything else the same. Sample drivers had the following coverage limits:
Collision coverage is very important for protecting your vehicle against the financial loss that comes with physical damage to your vehicle. It's not hard to get into an accident. When an accident happens, someone is always at fault, and that could be you. Collision insurance will cover damage from a collision with another vehicle, tree, pole, guardrail and most other possible roadway hazards.
Pollution insurance usually takes the form of first-party coverage for contamination of insured property either by external or on-site sources. Coverage is also afforded for liability to third parties arising from contamination of air, water, or land due to the sudden and accidental release of hazardous materials from the insured site. The policy usually covers the costs of cleanup and may include coverage for releases from underground storage tanks. Intentional acts are specifically excluded.
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.
While there are a couple of benefits of collision insurance, the main one is that you can file a claim and receive reimbursement regardless of who was at fault. Collision claims usually get processed faster than property damage claims because the insurance company does not have to spend time investigating who was at-fault. Another benefit is that you only deal with your own insurance company, rather than another insurer with less incentive to pay for your claim. Collision insurance can also be used toward your rental car in most cases, which can spare you from having to buy rental car insurance.
Certain insurance products and practices have been described as rent-seeking by critics. 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. 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.
In the European Union, the Third Non-Life Directive and the Third Life Directive, both passed in 1992 and effective 1994, created a single insurance market in Europe and allowed insurance companies to offer insurance anywhere in the EU (subject to permission from authority in the head office) and allowed insurance consumers to purchase insurance from any insurer in the EU. As far as insurance in the United Kingdom, the Financial Services Authority took over insurance regulation from the General Insurance Standards Council in 2005; laws passed include the Insurance Companies Act 1973 and another in 1982, and reforms to warranty and other aspects under discussion as of 2012.
Comprehensive car insurance covers damages from an "act of God," or events that are not caused by a car driving into something else. An "act of God" can include things like damage from a heavy tree branch falling on your car. Since you have no control over when or why a tree branch would fall on your car, this kind of accident would be covered under your comprehensive policy.
