What is defined as premium discrimination against policyholders?

Premium discrimination against policyholders refers to the practice of providing different premiums to different policyholders based on factors unrelated to risk assessment or underwriting standards. Rebating specifically describes a situation where an insurer provides part of the premium back to the policyholder as an inducement to purchase or retain a policy. This creates an unfair advantage and discriminatory pricing because it encourages a situation where insured individuals or groups receive varying benefits not based on their actual risk profile.

In contrast, the other options involve misconduct or unethical practices related to policy arrangements but do not directly pertain to the concept of premium discrimination. Dating the policy a month in advance may impact when coverage starts but doesn't inherently discriminate on premium basis; providing false information is also misleading and dishonest but does not constitute premium discrimination. Twisting involves persuading a policyholder to replace one insurance policy with another under false pretenses, which is not directly related to the premium structure itself. Thus, rebating is the correct definition of premium discrimination against policyholders.
