Costs, Insurability, and underwritingThe 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 in  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 have been age, gender,  and use of tobacco. More recently in the US, preferred class specific  tables were introduced. The mortality tables provide a baseline for the  cost of insurance. In practice, these mortality tables are used in  conjunction with the health and family history of the individual  applying for a policy in order to determine premium 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  90's 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 select 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 that 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 of a large group 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). Administrative and sales commissions  need to be accounted for in order for this to make business sense. A 10  year policy for a 25 year old non-smoking male person 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.
   
  The insurance company receives the premiums from the policy owner  and invests them to create a pool of money from which it can pay claims  and finance the insurance company's operations. The majority of the  money that insurance companies make comes directly from premiums paid,  as money gained through investment of premiums can never, in even the  most ideal market conditions, vest enough money per year to pay out  claims. Rates charged for life insurance increase with  the insurer's age because, statistically, people are more likely to die  as they get older.
   
  Given that adverse selection can have a negative impact on the  insurer's financial situation, the insurer investigates each proposed  insured individual unless the policy is below a company-established  minimum amount, beginning with the application process. Group Insurance  policies are an exception.
   
  This investigation and resulting evaluation of the risk is termed  underwriting. Health and lifestyle questions are asked. Certain  responses or information received may merit further investigation. Life  insurance companies in the United States support the Medical Information  Bureau (MIB), which is a clearinghouse 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 receives  permission to obtain information from the proposed insured's physicians.
   
  Underwriters will determine the purpose of insurance. The most common  is to protect the owner's family or financial interests in the event of  the insured's demise. 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 required by law to 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 (turned  down) or rated.[citation needed] Rating increases the premiums to  provide for additional risks relative to the particular  insured.
   
  Many companies use four general health categories for those evaluated  for a life insurance policy. These categories are Preferred Best,  Preferred, Standard, and Tobacco. Preferred Best is  reserved only for the healthiest individuals in the general population.  This means, for instance, 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 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. Most people are  in the Standard category. Profession, travel, 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 which provide  for more competitive offers in certain circumstances.
    Death Proceeds   Upon the insured's death, the insurer requires acceptable proof of  death before it pays the claim. The normal minimum proof required is a  death certificate and the insurer's claim form completed, signed (and  typically notarized). If the insured's death is suspicious and the  policy amount is large, the insurer may investigate the circumstances  surrounding the death before deciding whether it has an obligation to  pay the claim.
  Proceeds from the policy may be paid as a lump sum or as an annuity,  which is paid over time in regular recurring payments for either a  specified period or for a beneficiary's lifetime.
   
  The specific uses of the terms "insurance" and "assurance" are  sometimes confused. In general, in these jurisdictions "insurance"  refers to providing cover for an event that might happen (fire, theft,  flood, etc.), while "assurance" is the provision of cover for an event  that is certain to happen. "Insurance" is the generally accepted term,  but people using this description are liable to be corrected. In the  United States both forms of coverage are called "insurance", principally  due to many companies offering both types of policy, and rather than  refer to themselves using both insurance and assurance titles, they  instead use just one.
    Types of Life Insurance    Life insurance may be divided into two basic classes – temporary and  permanent or following subclasses – term, universal, whole life and  endowment life insurance.
 Term Insurance   Term assurance provides life insurance coverage for a specified term  of years in exchange for a specified premium. The policy does not  accumulate cash value. Term is generally considered "pure" insurance,  where the premium buys protection in the event of death and nothing  else.
   
  There are three key factors to be considered in term insurance:
   
  1. Face amount (protection or death benefit),
  2. Premium to be paid (cost to the insured), and
  3. Length of coverage (term).
   
  Various insurance companies sell term insurance with many different  combinations of these three parameters. The face amount can remain  constant or decline. The term can be for one or more years. The premium  can remain level or increase. Common types of term insurance include  Level, Annual Renewable and Mortgage insurance."
   
   
  Level Term policy has the premium fixed for a period of time longer  than a year. These terms are commonly 5, 10, 15, 20, 25, 30 and even 35  years. Level term is often used for long term planning and asset  management because premiums remain consistent year to year and can be  budgeted long term. At the end of the term, some policies contain a  renewal or conversion option. Guaranteed Renewal, the insurance company  guarantees it will issue a policy of equal or lesser amount without  regard to the insurability of the insured and with a premium set for the  insured's age at that time. Some companies however do not guarantee  renewal, and require proof of insurability to mitigate their risk and  decline renewing higher risk clients (for instance those that may be  terminal). Renewal that requires proof of insurability often includes a  conversion options that allows the insured to convert the term program  to a permanent one that the insurance company makes available. This can  force clients into a more expensive permanent program because of anti  selection if they need to continue coverage. Renewal and conversion  options can be very important when selecting a program.
   
  Annual renewable term is a one year policy but the insurance company  guarantees it will issue a policy of equal or lesser amount without  regard to the insurability of the insured and with a premium set for the  insured's age at that time.
   
  Another common type of term insurance is mortgage insurance, which is  usually a level premium, declining face value policy. The face amount  is intended to equal the amount of the mortgage on the policy owner’s  residence so the mortgage will be paid if the insured dies.
   
  A policy holder insures his life for a specified term. If he dies before that specified  term is up (with the exception of suicide see below), his estate or  named beneficiary receives a payout. If he does not die before the term  is up, he receives nothing. However, in some European countries (notably  Serbia), insurance policy is such that the policy holder receives the  amount he has insured himself to, or the amount he has paid to the  insurance company in the past years. Suicide used to be excluded from  ALL insurance policies[when?], however, after a number of court  judgments against the industry, payouts do occur on death by suicide  (presumably except for in the unlikely case that it can be shown that  the suicide was just to benefit from the policy). Generally, if an  insured person commits suicide within the first two policy years, the  insurer will return the premiums paid. However, a death benefit will  usually be paid if the suicide occurs after the two year period.
