In the United States, the underwriting loss of property and casualty insurance companies was $142.3 billion in the five years ending 2003. But overall profit for the same period was $68.4 billion, as the result of float. Some insurance industry insiders, most notably Hank Greenberg, do not believe that it is forever possible to sustain a profit from float without an underwriting profit as well, but this opinion is not universally held. Reliance on float for profit has led some industry experts to call insurance companies "investment companies that raise the money for their investments by selling insurance."[28]

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.[24] 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.
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]

Separate insurance contracts (i.e., insurance policies not bundled with loans or other kinds of contracts) were invented in Genoa in the 14th century, as were insurance pools backed by pledges of landed estates. The first known insurance contract dates from Genoa in 1347, and in the next century maritime insurance developed widely and premiums were intuitively varied with risks.[3] These new insurance contracts allowed insurance to be separated from investment, a separation of roles that first proved useful in marine insurance.
If you’ve recently purchased a new vehicle, you know that in order to drive in most states, you need to purchase a basic type of car insurance, but you may be overwhelmed by your coverage options. Comprehensive and collision are the two types of physical damage coverage available on car insurance policies. Both play an important role in keeping your vehicle in tip-top shape. Minor dents and dings all the way up to full-blown car crunching can be repaired, or the insurance company can at least pay out enough money to make you whole again.
The key difference in collision vs. comprehensive coverage is that, to a certain extent, the element of the car driver's control. As we have stated before, collision insurance will typically cover events within a motorist's control, or when another vehicle collides with your car. Comprehensive coverage generally falls under "acts of God or nature," that are typically out of your control when driving. These can include such events as a spooked deer, a heavy hailstorm, or a carjacking.
Definite loss: The loss takes place at a known time, in a known place, and from a known cause. The classic example is death of an insured person on a life insurance policy. Fire, automobile accidents, and worker injuries may all easily meet this criterion. Other types of losses may only be definite in theory. Occupational disease, for instance, may involve prolonged exposure to injurious conditions where no specific time, place, or cause is identifiable. Ideally, the time, place, and cause of a loss should be clear enough that a reasonable person, with sufficient information, could objectively verify all three elements.
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.

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.

My previous homeowners insurance increased rates every year regardless of claim history, credit, and market appraisal. I wanted to find something better, and I heard about Standard Insurance on the radio. I called and saved $770 per year on homeowners insurance! I thought my auto policy couldn’t get any lower than what it was, but I asked about bundling anyway. I was able to save $360 per year on auto insurance with no change in coverage! Plus, if I ever have to call Standard a real life local agent answers and is able to help me right away.
