What insurers sell is protection against
economic loss. These losses are outlined in
contracts or documents known as insurance
policies. Insurers that cover life and health usually
do not cover property or liability, which is the
domain of property/casualty insurers.
Life and health insurers cover three general
areas:
Protection against premature death.
Protection against poor health or unexpected
medical costs.
Protection against outliving one’s financial
resources.
Nonlife insurers, known as the property/casualty
sector in the United States and Canada, in general
offer two basic forms of coverage:
Property insurance provides protection against
most risks to tangible property occurring as the
result of collision, fire, flood, earthquake, theft
or other perils.
Casualty, or liability, insurance is broader than
property and is often coverage of an individual
or organization for negligent acts or omissions.
A well-known form of casualty insurance, auto
liability coverage, protects drivers in the event they
are found to be at fault in an accident.
A driver found to be at fault may be responsible
for medical expenses, repairs and restitution to
other people involved in the incident.
How Insurers Make Money
Insurance companies primarily make money in
two ways: from investments and by generating an
underwriting profit—that is, collecting premium
that exceeds insured losses and related expenses.
It all begins with underwriting. Insurers,
whether life or nonlife, must assess the risk and
gauge the likelihood of claims and the value of
those claims.
Insurance companies invest assets that are set
aside to pay claims brought by policyholders. The
interval between the time the insurer receives the
premium and the time a claim against that policy is
made is known as the “float.”
If an insurer has predominantly short-term
obligations, asset portfolios should be relatively
liquid in nature (i.e., publicly traded bonds,
commercial paper and cash).
If the needs are long term, a portfolio
containing fixed-income securities, such as bonds

and mortgage loans, may also include preferred
and common stocks, real estate and a variety of
alternative asset classes.
Life insurers also establish separate accounts
for nonguaranteed insurance products, such as
variable life insurance or annuities, which provide
for investment decisions by policyholders.
Property/casualty insurers traditionally have
been more conservative with the asset side of their
balance sheets, primarily due to the high levels of
risk on the liability side. For example, catastrophe
losses can wipe out years of accumulated
premiums in some lines.
In the end, the insurer builds up a diversified
portfolio of financial assets that will eventually
be used to pay off any future claims brought by
policyholders.
The global recession of the previous decade
hurt nearly all aspects of the insurance industry, as
many companies experienced declining revenues
and investment losses. Companies that were
trading riskier instruments such as credit default
swaps suffered most severely.
Few winners emerged. However, the mutual
insurance sector managed to remain somewhat
unscathed by the downturn. Meanwhile, a chronic
low interest rate environment limited the ability
of life and other insurers to benefit from fixed
investments such as bonds. That may be changing,
depending on economic conditions that could spur
higher inflation.
The Economics of Insurance
More than 2,603 single property/casualty
companies and 752 single life/health insurance
companies are included in AM Best’s files for
the United States and Canada. AM Best’s global
database includes information on more than
10,812 insurance companies worldwide. Insurers
pay claims in property, liability, life, health, annuity,
reinsurance and other forms of coverage. In the
United States alone, the broader insurance industry
provides employment to 2.8 million people.
Insurance organizations play a vital role in
the U.S. and other economies. They protect
individuals and businesses from financial loss.
Money they receive as premiums is invested in the
economy. Protection from financial loss provides
a sense of security to individuals and businesses,
which are freer to pursue business and personal
