Life insurance - Costs, insurability and underwriting

The insurer (the life insurance company) calculates the policy prices with intent to fund claims to be paid and administrative costs, and to make a profit. The cost of insurance is determined using mortality tables calculated by actuaries. Actuaries are professionals who employ actuarial science, which is based on mathematics (primarily probability and statistics). Mortality tables are statistically based tables showing expected annual mortality rates. It is possible to derive life expectancy estimates from these mortality assumptions. Such estimates can be important in taxation regulation.
The three main variables in a mortality table are commonly age, gender, and use of tobacco, but more recently in the US, preferred class-specific tables have been introduced. The mortality tables provide a baseline for the cost of insurance, but in practice these mortality tables are used in conjunction with the health and family history of the individual applying for a policy to determine premiums and insurability. Mortality tables currently in use by life insurance companies in the United States are individually modified by each company using pooled industry experience studies as a starting point. In the 1980s and 90s, the SOA 1975–80 Basic Select & Ultimate tables were the typical reference points, while the 2001 VBT and 2001 CSO tables were published more recently. The newer tables include separate mortality tables for smokers and non-smokers, and the CSO tables include separate tables for preferred classes.
Recent US mortality tables predict that roughly 0.35 in 1,000 non-smoking males aged 25 will die during the first year of coverage after underwriting. Mortality approximately doubles for every extra ten years of age, so the mortality rate in the first year for underwritten non-smoking men is about 2.5 in 1,000 people at age 65. Compare this with the US population male mortality rates of 1.3 per 1,000 at age 25 and 19.3 at age 65 (without regard to health or smoking status).
The mortality of underwritten persons rises much more quickly than the general population. At the end of 10 years the mortality of that 25 year-old, non-smoking male is 0.66/1000/year. Consequently, in a group of one thousand 25-year-old males with a $100,000 policy, all of average health, a life insurance company would have to collect approximately $50 a year from each participant to cover the relatively few expected claims. (0.35 to 0.66 expected deaths in each year x $100,000 payout per death = $35 per policy). Other costs, such as administrative and sales expenses, also need to be considered when setting the premiums. A 10 year policy for a 25-year-old non-smoking male with preferred medical history may get offers as low as $90 per year for a $100,000 policy in the competitive US life insurance market.
Most of the revenue received by insurance companies consists of premiums paid by policy holders, with some additional money being made through the investment of some of the cash raised from premiums. Rates charged for life insurance increase with the insurer's age because, statistically, people are more likely to die as they get older. The insurance company will investigate the health of and applicant for a policy to assess the likelihood of incurring a claim, in the same way that a bank would investigate an applicant for a loan to assess the likelihood of a default. Group Insurance policies are an exception to this. This investigation and resulting evaluation of the risk is termed underwriting. Health and lifestyle questions are asked, with certain responses or revelations possibly meriting further investigation. Life insurance companies in the United States support the Medical Information Bureau (MIB), which is a clearing house of information on persons who have applied for life insurance with participating companies in the last seven years. As part of the application, the insurer often requires the applicant's permission to obtain information from their physicians.
Underwriters will determine the purpose of insurance; the most common being to protect the owner's family or financial interests in the event of the insured's death. Other purposes include estate planning or, in the case of cash-value contracts, investment for retirement planning. Bank loans or buy-sell provisions of business agreements are another acceptable purpose.
Life insurance companies are never legally required underwrite or to provide coverage to anyone, with the exception of Civil Rights Act compliance requirements. Insurance companies alone determine insurability, and some people, for their own health or lifestyle reasons, are deemed uninsurable. The policy can be declined or rated (increasing the premium amount to compensate for a greater probability of a claim).[citation needed]
Many companies separate applicants into four general categories. These categories are preferred best, preferred, standard, and tobacco.[citation needed] Preferred best is reserved only for the healthiest individuals in the general population. This may mean, that the proposed insured has no adverse medical history, is not under medication for any condition, and his family (immediate and extended) have no history of early-onset cancer, diabetes, or other conditions. Preferred means that the proposed insured is currently under medication for a medical condition and has a family history of particular illnesses.[citation needed] Most people are in the standard category.[citation needed] Profession, travel history, and lifestyle factor into whether the proposed insured will be granted a policy, and which category the insured falls. For example, a person who would otherwise be classified as preferred best may be denied a policy if he or she travels to a high risk country.[citation needed] Underwriting practices can vary from insurer to insurer, encouraging competition.
