An entity which provides insurance is known as an insurer, insurance company, insurance carrier or underwriter. A person or entity who buys insurance is known as an insured or as a policyholder. The insurance transaction involves the insured assuming a guaranteed and known relatively small loss in the form of payment to the insurer in exchange for the insurer's promise to compensate the insured in the event of a covered loss. The loss may or may not be financial, but it must be reducible to financial terms, and usually involves something in which the insured has an insurable interest established by ownership, possession, or pre-existing relationship.
Life insurance provides a monetary benefit to a decedent's family or other designated beneficiary, and may specifically provide for income to an insured person's family, burial, funeral and other final expenses. Life insurance policies often allow the option of having the proceeds paid to the beneficiary either in a lump sum cash payment or an annuity. In most states, a person cannot purchase a policy on another person without their knowledge.
By the late 19th century governments began to initiate national insurance programs against sickness and old age. Germany built on a tradition of welfare programs in Prussia and Saxony that began as early as in the 1840s. In the 1880s Chancellor Otto von Bismarck introduced old age pensions, accident insurance and medical care that formed the basis for Germany's welfare state.[11][12] In Britain more extensive legislation was introduced by the Liberal government in the 1911 National Insurance Act. This gave the British working classes the first contributory system of insurance against illness and unemployment.[13] This system was greatly expanded after the Second World War under the influence of the Beveridge Report, to form the first modern welfare state.[11][14]

When your vehicle is damaged in an accident, collision insurance is an optional coverage that pays the cost of repairing or replacing it, minus the amount of your deductible. Collisions can involve another vehicle or an object, like a guardrail or a tree. If you lease or finance your vehicle, you may be required by your lender to purchase collision insurance coverage.

Some communities prefer to create virtual insurance amongst themselves by other means than contractual risk transfer, which assigns explicit numerical values to risk. A number of religious groups, including the Amish and some Muslim groups, depend on support provided by their communities when disasters strike. The risk presented by any given person is assumed collectively by the community who all bear the cost of rebuilding lost property and supporting people whose needs are suddenly greater after a loss of some kind. In supportive communities where others can be trusted to follow community leaders, this tacit form of insurance can work. In this manner the community can even out the extreme differences in insurability that exist among its members. Some further justification is also provided by invoking the moral hazard of explicit insurance contracts.

In the United States, the tax on interest income on life insurance policies and annuities is generally deferred. However, in some cases the benefit derived from tax deferral may be offset by a low return. This depends upon the insuring company, the type of policy and other variables (mortality, market return, etc.). Moreover, other income tax saving vehicles (e.g., IRAs, 401(k) plans, Roth IRAs) may be better alternatives for value accumulation.

An insurance underwriter's job is to evaluate a given risk as to the likelihood that a loss will occur. Any factor that causes a greater likelihood of loss should theoretically be charged a higher rate. This basic principle of insurance must be followed if insurance companies are to remain solvent.[citation needed] Thus, "discrimination" against (i.e., negative differential treatment of) potential insureds in the risk evaluation and premium-setting process is a necessary by-product of the fundamentals of insurance underwriting. For instance, insurers charge older people significantly higher premiums than they charge younger people for term life insurance. Older people are thus treated differently from younger people (i.e., a distinction is made, discrimination occurs). The rationale for the differential treatment goes to the heart of the risk a life insurer takes: Old people are likely to die sooner than young people, so the risk of loss (the insured's death) is greater in any given period of time and therefore the risk premium must be higher to cover the greater risk. However, treating insureds differently when there is no actuarially sound reason for doing so is unlawful discrimination.
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.

Global insurance premiums grew by 2.7% in inflation-adjusted terms in 2010 to $4.3 trillion, climbing above pre-crisis levels. The return to growth and record premiums generated during the year followed two years of decline in real terms. Life insurance premiums increased by 3.2% in 2010 and non-life premiums by 2.1%. While industrialised countries saw an increase in premiums of around 1.4%, insurance markets in emerging economies saw rapid expansion with 11% growth in premium income. The global insurance industry was sufficiently capitalised to withstand the financial crisis of 2008 and 2009 and most insurance companies restored their capital to pre-crisis levels by the end of 2010. With the continuation of the gradual recovery of the global economy, it is likely the insurance industry will continue to see growth in premium income both in industrialised countries and emerging markets in 2011.
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 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.
