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.
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]

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.
A history of chronic disease or other potential health issues with an individual or family, such as heart disease or cancer, may result in paying higher premiums. Obesity, alcohol consumption, or smoking can affect rates as well. An applicant typically goes through a medical exam to determine whether he has high blood pressure or other signs of potential health issues that may result in premature death for the applicant and increased risk for the insurance company. People in good health typically pay lower life insurance premiums.
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]
Your collision deductible is the amount of money you will pay out-of-pocket in the event that a collision damages your car. When deciding on the amount of your deductible, evaluate the age of your vehicle, how much you think repairs might cost you, and your willingness to pay for repairs under the amount of the deductible. For instance, if you hit a concrete barrier and you have a $500 deductible, you would pay $500 and Liberty Mutual would cover the rest of the repair costs above that amount. A higher collision deductible means that you will cover more of the cost of repairs when they arise, which in turn lowers your monthly premium.
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.
The main difference between collision and comprehensive coverage comes down to the question of what the driver controls. Collision insurance will 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," or things that are typically out of your control when driving. These can include events such as a spooked deer, a heavy hailstorm, or a carjacking.
