The type of policy where 80% to 90% of the premium is invested in traditional fixed income securities and the remainder of the premium is invested in contracts tied to a stipulated stock index is:

Universal life insurance policies feature flexible premium payments and adjustable death benefits, offering policyholders the ability to vary their coverage and savings components over time. However, universal life policies do not specifically allocate funds towards stock index contracts as seen in equity index whole life policies.

Variable life insurance policies allow policyholders to invest their premiums into separate accounts with varying investment options such as stocks, bonds, or money market funds. These policies offer the potential for higher returns but also carry increased investment risks compared to equity index whole life policies due to the direct exposure to market fluctuations.

Whole life insurance provides coverage for the policyholder's entire life and includes a cash value accumulation component. Premiums paid for whole life policies are typically invested by the insurance company, but these investments do not specifically involve a split between traditional fixed income securities and stock index contracts as outlined in equity index whole life policies.
