Introduction
Insurance represents a monetary form of managing risk that can cover a variety of assets
or a given behavior. For instance, actors insure their looks and bodies in case they get injured
while working which could then cost them time and ability to get new acting jobs (i.e. loss of
income). Businesses insure financial investments in case they go south and turn into a total
loss of principal funds invested.
For insurance to work and be effective it requires:
1) an agreement between the parties spelling out exactly what is
covered and what is not,
2) an exchange of consideration which typically involves a fee in
exchange for financial coverage of risk during a limited time
period, and
3) and means for the insurer to spread the accepted risk and not go bankrupt (which then makes
the insurance policy worthless to the holder/consumer).
However, insurers don't simply hang out a shingle and blindly accept any and all risks that come
to the store. They pick and choose those consumer or business risks that are manageable as a
group and can still overall provide a profit to the insurer. Insurance providers do this by accepting
a large pool of clients and charging each of them varying fees based on the same set of risk
rules. In doing so, when a small percentage of the pool submits claims for coverage, the fee
revenue from everyone in total can not only offset the cost of the claims but still provides the
insurer net profit after the coverage periods have ended.
To ensure that the pool of coverage remains profitable, insurers use a number of statistical tools
and actuarial services to determine risk breakpoints in various types of coverage and behavior.
For instance, automobile coverage will look at factors such as the type of car, age of the driver,
number of past tickets and accidents, location, state rules and laws, the insurer's own past
performance covering auto drivers, what the competition charges for similar coverage, and
pending changes coming in the near future that would affect the provider.
All of these factors then get relabeled with a monetary value and when
combined build the rate tables charged to a client. While it sounds
simple, a large amount of data gets accumulated and compiled regularly
to build each distinct rate in an insurance rate table used.
Risk and the cost of insurance for the client are then modified by how
much coverage the party wants. If they are willing to take on a sizable
deductible (i.e. a portion of the risk is self-assumed) then an insurer can
lower a policy price charged. If the client's preference only uses the
insurance for catastrophic purposes and not annoyances, then the cost
can go down further.
The key point to remember about insurance is that it's negotiable. There is no set-in-stone cost or
rate for a specific insurance policy, and many times the same type of coverage can vary by
hundreds of dollars per period between two individuals with the same risk, same factors, and
same preferences for coverage. This principle applies to all types of insurance, with the more
common types discussed in more detail on the following pages.
