Which of the following statements is correct regarding endorsements and premiums?

The statement that endorsements typically require an additional premium is correct because, in insurance policies, endorsements serve as modifications or additions to the original terms of the policy. They can provide additional coverage, enhance existing coverage, or clarify the policy terms.

When an endorsement adds coverage or increases the risk for the insurer, it usually results in an increased premium. Insurance companies assess the additional risk associated with the endorsement and adjust the premium accordingly, meaning the policyholder may need to pay more when an endorsement is added.

In contrast, while some endorsements could potentially adjust premiums downwards or remain neutral in cost, most commonly, they suggest an additional financial responsibility for the insured. Hence, it's essential for policyholders to understand that endorsements typically imply a change that might involve a premium increase.
