All of the following are supplemental payments found in liability policies EXCEPT?

In liability insurance policies, supplemental payments are those that extend coverage beyond the standard policy limits and typically relate to the costs incurred during the process of defending against a claim. The correct answer, which indicates that medical payments to injured parties are not considered a supplemental payment, aligns with the typical definitions found in liability coverage.

Supplemental payments generally include things like defense costs, which encompass expenses that the insurer incurs while defending the insured. This often includes attorney fees and court costs. Interest on judgments is also a supplemental payment since it is incurred after a judgment is made against the insured and is often covered to ensure the insured is not financially burdened beyond their policy limits in such situations.

Medical payments, on the other hand, are designed to cover costs associated with injuries sustained by third parties and are typically included as a separate coverage within the liability policy, often referred to as medical payments coverage. They are fixed and do not fall under the category of supplemental payments that directly correspond to defense costs or additional obligations that arise from a liability claim.

Thus, in the context of liability policies, medical payments for injured parties are distinctly categorized apart from supplemental payments related to defense and judgment costs.
