The simplest form of term life insurance is for a term of one year. The death benefit would be paid by the insurance company if the insured died during the one-year term, while no benefit is paid if the insured dies one day after the last day of the one-year term. The premium paid is then based on the expected
probability of the insured dying in that one year. Because the likelihood of dying in the next year is low for anyone that the insurer would accept for the coverage, purchase of only one year of coverage is rare. One of the main challenges to renewal experienced with some of these policies is requiring proof of
insurability. For instance the insured could acquire a
terminal illness within the term, but not actually die until after the term expires. Because of the terminal illness, the purchaser would likely be
uninsurable after the expiration of the initial term, and would be unable to renew the policy or purchase a new one. Some policies offer a feature called guaranteed reinsurability that allows the insured to renew without proof of insurability. A version of term insurance which
is commonly purchased is
annual renewable term (ART). In this form, the premium is paid for one year of coverage, but the policy is guaranteed to be able to be continued each year for a given period of years. This period varies from 10 to 30 years, or occasionally until age 95. As the insured ages, the premiums increase with each renewal period, eventually becoming financially inviable as the rates for a policy would eventually exceed the cost of a permanent policy. In this form the premium is slightly higher than for a single year's coverage, but the chances of the benefit being paid are much higher.
Basic pricing assumptions for annual renewable term life insurance Actuarially, there are three basic pricing assumptions that go into every type of life insurance: • Mortality—How many individuals will die in a given year using a large sample size—EG, The 1980 CSO Mortality Table or the newer 2001 CSO Mortality Table which are compiled by the FDC. Most life insurance companies use their own proprietary mortality experience based on their own internal set of statistics. The CSO Mortality Tables reflect total population figures within the US and do not reflect how a life insurance company screens its applicants for good health during the policy underwriting phase of the policy issue process. Corporate mortality will most likely always be more favorable than CSO tables as a result. In rare cases some companies have recently increased policy mortality costs on existing business segments due to much lower than anticipated investment returns, • Assumed Net Investment Return—EG Current industry average return of 5.5% Annual Yield by the life insurance company. In the early 1980s interest/return assumptions were well over 10% to be sustained over the life of the policy. • Internal Administrative Expenses—Generally these are proprietary figures which include, mainly, policy acquisition costs (sales commissions to selling agents and brokers), and general home office expenses. These pricing assumptions are universal among the various types of individual life insurance policies. It's important to understand these components when considering term life insurance because there is no cash accumulation component inherent to this type of policy. Buyers of this type of insurance typically seek the maximum death benefit component with the lowest possible premium. In the competitive term life insurance market the premium range, for similar policies of the same duration, is quite small. All of the above referenced variations of term life policies are derived from these basic components. ==Level term life insurance==
