Mortality tables

Definition

Mortality tables are statistical charts that provide the likelihood of death for individuals at different ages and can help insurers estimate life expectancy. These tables are essential tools that enable insurance companies to assess risk and determine appropriate premiums for life insurance policies, using historical data about death rates to predict future trends.

Review Questions

• How do mortality tables influence the underwriting process in insurance?
  • Mortality tables provide critical data that influences the underwriting process by helping underwriters assess the risk associated with insuring an individual. By analyzing historical mortality rates based on age and other factors, underwriters can determine appropriate premiums that reflect the level of risk. This ensures that premiums collected adequately cover potential claims while maintaining the insurer's profitability.
• Discuss how mortality tables can impact premium calculation methods for different types of life insurance products.
  • Mortality tables significantly impact premium calculation methods by providing essential data on expected mortality rates for various demographics. For term life insurance, premiums are often based on shorter time frames and specific age groups, while whole life policies require longer-term projections of mortality. Insurers use mortality tables to adjust premiums according to the anticipated life expectancy of policyholders, ensuring that they remain competitive while adequately covering their liabilities.
• Evaluate the potential implications of inaccurate mortality tables on an insurance company's financial health and policyholder trust.
  • Inaccurate mortality tables can have serious implications for an insurance company's financial health, as they may lead to incorrect premium pricing or inadequate reserves for future claims. If mortality rates are underestimated, the insurer could face unexpected financial strain due to higher-than-anticipated payouts. This situation could erode policyholder trust if companies struggle to meet their obligations, potentially resulting in regulatory scrutiny and damage to their reputation in the market.
