Which policy provision would automatically broaden coverage without requiring additional premium?

The Liberalization provision is designed to automatically expand coverage under an insurance policy without requiring the insured to pay an additional premium. This provision is beneficial to policyholders as it ensures that when an insurer introduces new coverages or benefits that enhance the overall protection offered by the policy, these improvements are automatically applied to existing policies.

This approach not only enhances customer satisfaction by providing broader coverage but also encourages policyholders to stay with their insurance provider as they receive upgraded protections without any extra cost. It exemplifies a commitment from the insurer to keep their policies updated and relevant to current risks and standards.

In contrast, endorsements typically require a policyholder to pay extra premiums for added coverage, exclusions denote specific perils that are not covered by the policy, and restrictions limit the coverage provided. None of these options reflect the automatic enhancement of coverage without additional cost that is offered by the Liberalization provision.
