Final answer:
Current-assumption whole life insurance policies guarantee a competitive interest rate for at least the duration of the policy.
Step-by-step explanation:
In general, current-assumption whole life insurance policies guarantee a competitive interest rate for at least the duration of the policy. The interest rate is determined by the insurance company and is typically based on market conditions and the company's investment performance. This means that the policyholder can expect to earn a certain rate of return on the cash value of their policy, which is an accumulation of premiums paid over time.
